In 1928 in St. Paul, Minnesota, USA, Richard Drew invented Scotch tape. Tapes can be divided according to their functions: high-temperature tape, double-sided tape, insulating tape, special tape, pressure-sensitive tape, and die-cut tape. Different functions are suitable for different industry needs. A layer of adhesive is coated on the surface of the tape so that the tape can stick to items. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of adhesives. In modern times, various polymers are widely used. . Basic introduction Chinese name: tape Foreign name: adhesive tape Composition: base material, adhesive type: cloth tape, kraft paper tape invention process, usage principle, classification, specifications, single side, heat sealing, butyl, transparent, insulation, anti-corrosion, Prohibition, Marla, iron sheet composite, polyimide, foam, flooring, high temperature, choice, choice distinction, related knowledge, related enterprises, development situation, invention process of Scotch Tape in 1928 by Richard Drew, Minnesota, USA St. Paul applied in the United Kingdom and the United States on May 30, 1928. Drew developed a very light, one-pressure adhesive. The first attempt was not sticky enough, so Drew was told: "Put this thing on." Take it back to your Scotch bosses and ask them to put more glue in it!" ("Scotch" means "stingy"). But during the Great Depression, people found hundreds of uses for this tape, ranging from supplements to It has many uses, from clothing to protecting broken eggs. Principle of use: Tape is composed of two parts: a base material and an adhesive, which are used to connect two or more disconnected objects together on their surfaces. There is a layer of adhesive. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main ingredient of adhesives; in modern times, various polymers are widely used because they can stick to things. Bonds are formed between the molecules of the adhesive itself and the molecules of the objects to be connected. This bond can firmly bind the molecules together. The composition of the adhesive varies according to different brands and types. . Classification according to the base material: can be divided into BOPP tape, cloth tape, kraft paper tape, masking tape, fiber tape, PVC tape, PE foam tape, etc. According to the application scope: can be divided into warning tape, carpet tape. , electrical tape, protective film paper tape, stretch film tape, sealing tape, module tape, etc. According to market penetration: it can be divided into ordinary tape and special tape. According to the application environment temperature: it can be divided into low temperature tape and normal temperature tape. Tape, high-temperature tape. Divided according to adhesion: single-sided tape and double-sided tape. Specifications 1) Jumbo Roll is the prototype tape coming off the machine, with a width of 1 meter to 1.5 meters and a length of several hundred meters to several meters. Kilometers, depending on different substrates. 2) Log Roll is the product after rewinding the parent roll. The width remains unchanged and the length varies according to the requirements (generally 100 meters, 50 meters, 25 meters, 10 meters, 5 meters). 3) Slit Roll small roll (finished roll) is a product on the general market. The single-sided tape can be used for packaging or temporary fixing of objects. It can be easily torn off without any tools. There is no colloid residue on the adhered surface after tearing off. It is made of embossed PVC as the base material and is easy to tear without leaving any glue residue. The new surface tape product S8855B has been developed as a finished product. Functionally, it can partially replace the existing waterproof cloth-based single-sided tape S9522R or 4701, and the price is more competitive. The tape has been trial-sold at the Beijing East Road store. The color available in advance is earthy brown and can be cut and produced according to customer specifications. S8855B heat-sealing tape is heated by special equipment (hot air seam sealing machine or high-frequency heat sealing machine) and sewn at the pinholes of the knitted bones of raincoats, tents, air balloons and other waterproof and gas-proof products to achieve sealing (Anti-leakage, anti-air leakage) tape. As we all know, needle holes will definitely appear during the processing and production of clothing, and of course waterproof series are no exception. How to ensure that these needle holes do not leak? Such a seemingly simple problem has puzzled us for thousands of years, because ordinary tape has no adhesion when exposed to water.
In the 20th century, only a few countries in the world used it, and the material was very expensive. It only appeared in countries with relatively developed military industries such as the United States and the Soviet Union, and it was only used in aerospace technology. The technology is kept secret from other countries. Types of heat sealing tapes: PVC, composite PU, pure PU (TPU), hot melt film, rubber tape, non-woven tape, three-layer cloth tape. Technical standards for heat sealing tape: European toxic elements EN71.PART3: 1994 safety testing standard EU toxic elements EN1122: 2001 safety testing standard EU 2002/61/EC restricted ammonia dye standard does not contain Vinyl Chloride Monomer Purpose of heat sealing tape: Heat Sealing tape is widely used in waterproof-related products such as cold-proof clothing, ski clothing, down jackets, navigation suits, diving suits, tents, car and boat covers, raincoats, motorcycle raincoats, waterproof shoes, and gas-proof products such as space suits, lift-off balloons, chemical protective clothing, etc. products.

Drew developed a very light, one-pressure adhesive that was later improved and invented. Scotch tape. The tape is based on the BOPP original film and is subjected to high-voltage corona to roughen one side of the surface. Then it is coated with glue and divided into small rolls. It is the tape we use daily. Tape glue is acrylic glue, also called pressure-sensitive glue, and its main ingredient is tincture. Tincture fat is a kind of high molecular activity substance, and the temperature has a certain influence on the molecular activity. The tincture content of the glue directly affects the use of the tape. The initial adhesive force of normal sealing tape is between ≥13 (steel ball number). The thickness of this tape glue is generally 22 microns, which is a standard thickness. Colored tapes are used for marking and masking purposes. Generally, beige and khaki are more common. The color of the colored tape is the color of the glue. Pinch the transparent tape together tightly and then pull it apart quickly. You can pull off one side of the tape and you can see the purity and transparency of the original film. Insulation Insulating tape specifically refers to the tape used by electricians to prevent leakage and act as an insulator. Insulating tape production process: It is made of polyvinyl chloride film as the base material and coated with rubber-type pressure-sensitive adhesive. Insulated rubber tape refers specifically to the tape used by electricians to prevent leakage and provide insulation. Also known as insulating tape, tape consists of a base tape and a pressure-sensitive adhesive layer. The base tape is generally made of cotton cloth, synthetic fiber fabric and plastic film, etc. The adhesive layer is made of rubber plus tackifying resin and other compounding agents, which has good viscosity and excellent insulation performance. Insulating tape has good insulation voltage resistance, flame retardancy, weather resistance and other characteristics, and is suitable for wire connection, electrical insulation protection and other characteristics.
Insulating tape is widely used in electrical work such as wrapping, jointing, insulation sealing of wires used under 380V voltage. There are two production processes: gluing method and gluing method. Production process: Made of polyvinyl chloride film as the base material and coated with rubber-type pressure-sensitive adhesive. In the process of using electricity, although people have noticed that the cross-sectional area of ??the power cord material has an impact on the safe use of electricity, they often do not pay enough attention to the use of insulating tape on the joints. Nowadays, the laying of power lines is becoming more and more complicated, and it can be found under wooden floors, in walls, in partitions, and in humid underground or water. If the insulating tape is used improperly, electric leakage will occur, endangering personal safety. Therefore, we must use insulating tape correctly. The power cord connectors are divided into " " word connection, "-" word connection, "T" word connection, etc. The joint should be tightly wrapped, smooth and without burrs. Otherwise, before disconnecting the thread, you should lightly press it with wire cutters, then wrap it to the pressure port, and then swing it left and right. The thread will be disconnected at the joint easily. If the joint is in a dry place, first wrap it with 2 layers of insulating black tape, then wrap it with 2 layers of plastic tape, then stretch it about 200 degrees with insulating self-adhesive tape, wrap it with 2 to 3 layers, and finally wrap it with 2 layers of plastic tape. Because the direct use of plastic tape has many disadvantages: the plastic tape is easy to dislocate and open over time; when the electrical load is heavy, the joints become hot, and the plastic tape is easy to melt and shrink; the power connectors are squeezed against each other in the junction box, and when the connectors have burrs, it is easy to Puncture plastic tape, etc. These hidden dangers will directly endanger personal safety, cause circuit short circuits, and cause fires. The above situation will not occur when using insulating black tape. It has a certain strength and flexibility, can be tightly wrapped at the joint for a long time, is densely shaped due to the influence of time and temperature, will not fall off, and is flame retardant. Furthermore, wrapping it with insulating black tape and then wrapping it with plastic tape can prevent moisture and rust. Of course, the insulating self-adhesive tape also has flaws. Although it has good waterproof performance, it is easy to break. Therefore, it is necessary to wrap two layers of plastic tape as a protective layer. The insulating self-adhesive tapes of the joints do not stick to each other and have better performance. Anti-corrosion and anti-corrosion tapes refer to adhesive tapes used for anti-corrosion wrapping, and are divided into cold-wrap tapes and hot-wrap tapes. Cold-wrap tapes generally include polyethylene (composite) anti-corrosion tapes, polypropylene reinforced fiber anti-corrosion tapes, and aluminum foil anti-UV anti-corrosion tapes. , Polyethylene 660 (modified asphalt) tape, double-sided tape anti-corrosion inner tape (this tape is rarely used in China, but it is very practical and widely used abroad, and is generally used for export) and epoxy coal pitch anti-corrosion tape. The implementation standards are SY/T0414-98 and SY/T0447-96. Thermal tape is also called radiation cross-linked polyethylene heat shrinkable tape. During use, it needs to be heated to melt the glue before it can be used. It also needs to be supplemented with solvent-free epoxy coating to form a three-layer anti-corrosion structure. The implementation standard is SY /T0413-2002. Anti-corrosion tape is a kind of metal foil or conductive cloth with a highly conductive adhesive. Its conductive adhesive and conductive base material form a complete conductor. It can be bonded with any metal surface to complete electrical overlaps and gaps. of electrical closure. Barring conductive tape is an economical, easy-to-use barring material. Used to seal EMI suppression chambers, seams between housings and electronic equipment, wrap cables for suppression, provide a reliable grounding surface, and provide electrical contact to surfaces that cannot be welded. Mara Name: Mara Tape, also known as Silicone Mara Tape, Fire Ox Tape, Mara Tape. Marathon tape is suitable for: insulation in the electronics industry.

Features: Waterproof, high bonding strength, high tensile strength, strong adaptability to interface deformation and cracking. It has excellent chemical resistance, weather resistance and corrosion resistance. It does not flow at high temperatures of 80°C and does not crack at low temperatures of 40°C. Polyimide Polyimide tape, also known as Kapton tape, is based on polyimide film and uses imported organic silicon pressure-sensitive adhesive. It has high and low temperature resistance, acid and alkali resistance, solvent resistance, and electrical insulation (H level), radiation protection and other properties.
It is suitable for shielding electronic circuit board wave soldering, protecting golden fingers, high-end electrical insulation, motor insulation, and lithium battery positive and negative and ear fixation. Polyimide tape foam foam tape is made of PE or EVA as the base material, using acrylic oil pressure-sensitive adhesive, and is coated with release paper or release film as the isolation surface. Its performance is: it can fully absorb the voids of the adherend and overcome the uneven defects of the adherend. It has good buffering properties, excellent creep resistance, and can withstand loads for a long time. It is widely used in the construction industry and the automotive industry. Floor 1. The tape should be stored in the warehouse to avoid sunlight and rain; it is forbidden to contact with acid, alkali, oil and organic solvents, keep it clean and dry, 1m away from the discovery device, and the room temperature is between -15℃~40℃. Tape 2. The tape should be placed in a roll without folding. If stored for a long time, it should be turned once a quarter. 3. When loading and unloading the conveyor belt, it is best to use a crane and use rigging with beams to lift it smoothly to avoid damaging the belt edges. Do not load and unload the conveyor belt arbitrarily, which may cause loose coiling and throwing. 4. The type and specifications of the tape should be selected reasonably according to the use needs and specific conditions. 5. Tapes of different varieties, specifications, models, strengths, and layers of cloth must not be connected (grouped) and used together. 6. It is best to use hot vulcanization adhesive joints for conveyor belt joints to improve reliability and maintain high effective strength. 7. The diameter of the conveyor's transmission roller and the minimum pulley diameter of the conveyor belt should comply with relevant regulations. 8. Do not let the tape snake or creep. Keep the drag roller and vertical roller flexible, and the tension should be moderate. 9. When the conveyor is equipped with baffles and cleaning devices, wear and tear on the tape should be avoided. 10. Cleanliness is the basic condition for the good operation of the tape. Foreign substances will affect the tape's eccentricity, tension difference, and even breakage. 11. When early damage to the tape is found during use, the cause should be found and repaired in time to avoid adverse consequences. High temperature High temperature tape is an adhesive tape used in high temperature working environments. Mainly used in the electronics industry, the temperature resistance is usually between 120 degrees and 260 degrees. It is often used for spray painting, baking leather processing, coating masking and fixing in the electronic parts manufacturing process, printed circuit boards and high temperature processing masking. High temperature tapes include KAPTON high temperature tape; Teflon high temperature tape; high temperature masking tape; PET green high temperature tape; high temperature double-sided tape, etc. High-temperature tape has the following characteristics: 1.

Color printing packaging machines, plastic braiding and drawing machines, microwave drying, various conveyor belts and various bag making machines in the clothing hot-adhesive sealing and pressure packaging industry, and the hot-pressed sealing end of the sealing machine etc. There are many types of tapes to choose from, and there are also many types of adhesives on their surfaces. Therefore, the performance and strength of various brands of tapes are different. Therefore, you need to consider the following factors when purchasing tapes: What the tape needs to be adhered to Microporosity of the object: The sticking effect of the tape occurs when the moisture of the adhesive on the surface of the tape penetrates into the adhered object and dries quickly, making the tape become a part of the adhered object. Therefore, the adhesive tape becomes a part of the adhered object. The microporosity of the surface of the object to be adhered is very important for the selection of tape. If the object is more microporous or has greater hygroscopicity, you must use a tape with a rapid adhesive condensation. Otherwise, use a tape with a slower condensation speed or a tape with a slower condensation speed. Tapes that contain more adhesive. Adhesive on the surface of the tape: The tape is coated with adhesive on the bottom tape at the manufacturer. It usually needs to be fully dried before being sorted into rolls. If the adhesive tape is too wet, the tape itself will stick together very tightly, making it very difficult to use. They are difficult to open and some cannot be used at all.
Choose to distinguish the ordinary sealing and packaging tape (BOPP biaxially oriented polypropylene) in daily life. It is an indispensable daily necessities in any enterprise, company, and personal life. However, compared with the current domestic situation, although there are many manufacturers, the technology is uneven. Not even. Moreover, the technical content of the domestic tape industry is still at a very low stage, and the country does not have a clear choice for this. People often have a very ignorant understanding of tape, thinking that it is cheap and has good viscosity. In fact, these are wrong understandings and judgments. So how to choose the quality of tape? In fact, there are two standards for the quality of adhesive tape in use. One is the initial adhesive force and the other is the holding force. The two are inversely proportional. Generally speaking, tapes with adhesive strength lower than No. 10 have less glue coating, generally only about 20 microns, such as stationery tapes and tapes used for ordinary promotional bundling. The initial tack of normal sealing tape is between No. 15-20, and the thickness of this tape glue generally is 22-28 microns. It is the thickness that meets the standard. However, most of the tapes on the market are mixed with impurities, so the thickness increases. In order to cover the impurities, the glue is also mixed with toner, so the transparent tape appears egg yellow and light green. This kind of tape is generally inferior. How to distinguish between good and bad colored tape? For colored tapes, yellow and khaki are generally the most common. Pinch the stick tightly and then pull it apart quickly. You can pull off the glue on one side and you can see the purity and transparency of the original film. You can also look at the thickness of the glue. If there is no glue that is pulled apart or pulled apart in spots, there are a lot of impurities in the glue and the glue has no cohesion. The second is that there is too much water and it has evaporated. At this time, the initial adhesive force of this tape has dropped significantly, which can be distinguished by the feel. In fact, there are many ways to distinguish the quality of tape from bad. As long as you pay more attention in life, you can distinguish the quality of tape. Knowledge related to tape When removing the tape, due to the stickiness of the tape itself, it is easy to stick off the wall and other surface items. At this time, you only need to iron it with a steam iron, and the stickiness of the tape will be reduced. Just apply it gently. It can be removed by tearing it off without damaging walls and other items. Related enterprises The supply chain classification and distribution of each department of major global enterprises are summarized as follows: First-tier brands: 3M of the United States, TESA of Germany, and NITTO of Japan, all have factories in China, but high-tech products are generally produced locally; second-tier brands : Third-tier brands such as British Scapa, Japanese Sekisui, Japanese Teraoka, and Japanese SONY: Development Situation of Tape Companies in Taiwan and Mainland China With the development of the economy and the advancement of science and technology, China has become a major processing and production plant and consumer in the world's adhesive industry. Combined with many years of supporting experience. growing at a rate of 16 per year. In particular, adhesive tapes, protective films and self-adhesive tapes are widely used in electronics, communications, packaging, construction, papermaking, woodworking, aerospace, automobiles, textiles, metallurgy, machinery manufacturing, medical industries, etc. The adhesive industry has become my country's chemical industry. The most dynamic and important industry in the industry. The development of the tape industry mainly depends on the development of coal, steel, cement, ports, mining, petroleum, automobiles, textiles, light industry, machinery and other industries. Since the "Eleventh Five-Year Plan", my country's national economy has developed continuously and rapidly, driving the sustained and rapid growth of coal, steel, cement, automobiles, agricultural machinery, etc. Our country's coal, steel, and cement output ranks first in the world. At the same time, the country has taken measures to expand domestic demand, which are expected to continue for a long time. It will undoubtedly drive the development of building materials, automobiles, agricultural machinery, light industry and other industries. In addition, attaching importance to the work of "agriculture, rural areas and farmers" will also be carried out over a long period of time, which has opened up a broad long-term potential market for my country's adhesive tape work. Automotive tape is the fastest growing variety, which is closely related to the rapid development of China's automobile industry. The automobile industry is a pillar industry of China's national economy. In 2009, my country's automobile production and sales reached more than 13 million units, ranking first in the world. In the first eight months of 2010 alone, my country's automobile production and sales exceeded 11 million units, setting another record high and becoming the world's largest automobile consumer.
According to predictions from the China Machinery Industry Federation and the China Association of Automobile Manufacturers, my country's automobile production and sales will exceed the 16 million mark in 2010. The growth rate of automobile production and sales will slow down in the next few years, but will remain above 10. After more than 50 years of development, China's automobile industry has basically established a relatively complete automobile industry production system. Driven by the reform and opening up policy and stimulated by a strong domestic market, it has achieved rapid development. my country's automobile and parts exports It has also shown a trend of rapid development, with an average annual growth rate of nearly 50% from 2001 to 2009. In 2009, automobile product exports reached more than 30 billion US dollars. The international comparative advantage of my country's automobile products still exists, and the demand potential in the international market is huge. The output value of flame-retardant conveyor belts and V-belts used in the coal industry is predicted to grow at double digits every year. The petroleum industry is one of the important industries of the national economy and is developing steadily. The annual growth rate of petroleum is around 7. Especially with the start of the exploitation of offshore oil wells, the demand for adhesive tape will be increasing. With the acceleration of China's infrastructure construction, the number of construction machinery continues to increase. Every year, the output of China's construction machinery, including loaders, road rollers, graders, excavators, etc., increases by about 10%, and the demand for various major construction machinery exceeds hundreds of thousands. It is expected that a large number of construction machinery will be needed in recent years, which will bring significant opportunities for supporting tapes for construction machinery. With the improvement of China's agricultural mechanization, the output of agricultural machinery has increased year by year, and the tape for agricultural machinery has become a big market.
