1, hardness
difficult
Degree is one of the parameters that can best reflect the production process and technology of cast acrylic plate, and it is an important link of quality control. Hardness can reflect the purity of raw material PMMA, weather resistance and high temperature resistance of plate. Hardness directly affects
Whether the plate will shrink, bend and deform during processing, and whether the surface will be chapped. Hardness is one of the hard indexes to judge the quality of acrylic board, and the average Dallow hardness is about 8 or 9 degrees.
2. Thickness (acrylic tolerance)
Acrylic tolerance exists in the thickness of acrylic plate, so the control of acrylic tolerance is an important embodiment of quality management and production technology. The production of acrylic has the international ISO7823 standard.
Tolerance requirements of pouring plate: tolerance = (0.4+0. 1 x thickness)
Tolerance requirements of extruded board: tolerance = 3 mm thickness: 5%
3. Transparency/whiteness
Strict raw material selection, advanced formula follow-up and modern production technology ensure the excellent transparency and pure whiteness of the plate. After flame polishing, it is crystal clear.
Question 2: What is acrylic material? Is it different from plastic? Acrylic is commonly called "resin".
Question 3: Why does alcohol corrode plastic acrylic materials? Acrylic was corroded by alcohol mainly because of plasticizer (DOP? DBP), this plasticizer does not participate in the chemical reaction during the polymerization of acrylic acid.
Acrylic, also called PMMA or acrylic, comes from English acrylic. The chemical name is polymethyl methacrylate, which is an important plastic polymer material developed earlier. It has good transparency, chemical stability and weather resistance, easy dyeing, easy processing and beautiful appearance, and is widely used in the construction industry. Plexiglass products can usually be divided into pouring plate, extrusion plate and molding compound.
Question 4: Is acrylic transparent? The polymerization of acrylic acid was discovered by scientists in 1872, and methacrylate was successfully manufactured and developed in 1937. Humans are just officially mass-produced. Because of its high transparency, like crystal, it has the reputation of "Queen of Pigments". Because of its excellent toughness and good light transmittance, it was mainly used to manufacture aircraft doors, tank observation ports and bathtub production in the early days. The most typical ones used in the advertising industry are McDonald's, KFC and other door light boxes and signs. The surface of modern acrylic material is coated with high-intensity ultraviolet absorber, which is colorful, dazzling and penetrating at night. Acrylic blister light box, characterized by strong three-dimensional sense.

Classification, composition and characteristics of plastics Plastic is a widely used synthetic polymer material, and plastic products can be found everywhere in our daily life. From the toiletries used after getting up, the tableware used for breakfast, the stationery used for work and study, the cushions and mattresses used for rest, the casings of televisions, washing machines and computers, and lamps of various shapes that bring us light at night ... Plastic has gradually replaced many materials and utensils that have been used for decades and hundreds of years with its excellent performance, and has become an indispensable assistant in people's lives. Plastic combines the hardness of metal, the lightness of wood, the transparency of glass, the corrosion resistance of ceramics and the elasticity and toughness of rubber. Therefore, in addition to daily necessities, plastics are more widely used in aerospace, medical equipment, petrochemical, machinery manufacturing, national defense, construction and other industries. I. Classification of plastics
There are many kinds of plastics, so far there are about 300 kinds of plastics put into production in the world. There are many ways to classify plastics, and there are two commonly used methods:
1, according to the different properties of plastics after heating, it can be divided into thermoplastic and thermosetting plastics.
The molecular structure of thermoplastics is linear, which softens or melts when heated, can be shaped into a certain shape, and then hardens after cooling. It becomes soft when heated to a certain extent, and becomes hard after cooling. This process can be repeated many times. Such as polyvinyl chloride, polyethylene, polystyrene, etc. Thermoplastic molding process is relatively simple, can be produced continuously, and has quite high mechanical strength, so it develops rapidly.
The molecular structure of thermosetting plastics is a kind of bulk structure, which can be softened by heating and shaped into a certain shape. However, after heating to a certain extent or adding a small amount of curing agent, it will harden and set, and will not soften and deform after reheating. Thermosetting plastics, such as phenolic plastics, amino plastics, epoxy resins, etc. Can't be recycled after processing and molding. Thermosetting plastics are complicated in molding process and difficult to produce continuously, but they are good in heat resistance, difficult to deform and relatively low in price.
2. According to the different uses of plastics, they can be divided into general plastics and engineering plastics.
General plastics refer to plastics with large output, low price and wide application range, mainly including polyolefin, polyvinyl chloride, polystyrene, phenolic plastics and aminoplastics. Many products used in people's daily life are made of these general plastics.
Engineering plastics can be used as engineering structural materials instead of metals to manufacture machine parts. Such as polyamide, polycarbonate, polyoxymethylene, ABS resin, polytetrafluoroethylene, polyester, polysulfone, polyimide and the like. Engineering plastics have the characteristics of low density, high chemical stability, good mechanical properties, excellent electrical insulation and easy processing and molding. , widely used in automobiles, electrical appliances, chemicals, machinery, instrumentation and other industries, as well as aerospace, rockets, missiles and so on.
Second, the composition of plastic
The plastic we usually use is not a pure substance, it is made of many materials. Polymer (or synthetic resin) is the main component of plastic. In addition, in order to improve the properties of plastics, various auxiliary materials, such as fillers, plasticizers, lubricants, stabilizers, colorants, etc. , must be added to the polymer to become a plastic with good performance.
1, synthetic resin
Synthetic resin is the most important component in plastics, and its content in plastics is generally 40% ~ 100%. Because its high content and the nature of resin often determine the properties of plastics, people ...
Question 7: Is acrylic poisonous? Acrylic is poisonous when heated.
Smell it for a long time and have a headache
Long term contact
It is easy to cause infertility.
Polymethyl methacrylate (PMMA), commonly known as plexiglass or acrylic, has the advantages of high transparency, low price and easy mechanical addition, and is a commonly used glass substitute material.

tangible property
Density: 1. 19kg/dm 3 Light transmittance: 99% Impact strength ≥ 16kg/cm 3 Tensile strength ≥6 1Kg/m 3 Thermal deformation temperature ≥78℃ Thermal softening temperature ≥ 105℃ Acrylic should be The bonding method of acrylic should be tailored according to different needs. 502 can be lower, but chloroform with high requirements is not necessarily the best, and acetone is also needed, but it is best to have several mixed formulas.
Acrylic itself is nontoxic.
But the commonality of dust is the erosion of mucosal tissue.
It will cause pneumonia, emphysema and even lung cancer for a long time.
Dizziness is a by-product of lung discomfort and insufficient oxygen supply.
Moreover, machine noise and sulfur-containing toxic gases produced by production can also cause inflammation of other organs.
Volatile benzene odor is harmful to human kidney function.
This is mainly related to the raw materials used by processing units. Originally, acrylic is not toxic, but the processing unit bought acrylic in order to save costs, which is also recycled material, so there are other components in it, such as resin, which will volatilize during processing and become harmful gases.
Question 8: Will the acidic glass glue corrode the acrylic plate? Glass glue belongs to silica gel. Silicone glue can bond plastics. It has no corrosive effect on acrylic. Please refer to the product technical specifications for details.
Question 9: Will acrylic paint corrode the surface? There is a special acrylic paint, and it is best not to apply recycled and fire-thrown materials. I have cracked it in batches.
Question 10: What's the difference between organic board and acrylic? There are many sizes and colors of organic plates, but the colors of acrylic are relatively single.
