The construction glues we often talk about include 107 glue and 108 glue. Many people only know that 107 glue and 108 glue are two different construction glues, but they do not know that there is a difference between 107 glue and 108 glue. What are the differences? Next, let me tell you about the differences between 107 glue and 108 glue. 1. Introduction to 107 glue
1. Introduction to 107 glue
107 glue, also known as "cultured water", is a colorless or slightly yellow viscous liquid. It can be used alone as a binding glue and glue for books and periodicals. It can be used to paste wallpapers and plastic floors in building decoration. It is most commonly used to mix it with cement mortar to paste tiles. Especially if the wall is uneven, it can be used to smooth it. It can also be used complementary with 903. If the wall is uneven, 107 glue will have better results and the price will be lower.
The scientific name of 107 glue is polyvinyl formal adhesive, which is an adhesive formed from a solution or emulsion using water as the medium. Because 107 adhesive has the characteristics of non-flammable, low price, and easy to use, it is widely used in construction projects and can be used as building adhesives and the base material of various interior and exterior wall coatings and floor coatings.
2. The main function of 107 glue
107 glue is an industrial glue used to adhere plastic floors or wallpapers during building construction. 107 glue can also be used as book binding glue.
As an adhesive with water as the medium, 107 glue is non-flammable, easy to use and low in price. It is the basic material for various interior wall coatings, exterior wall coatings and floor coatings in building construction. 107 glue has high value in construction and decoration projects. It can not only be used in adhesives, polymer cement slurries, etc., but also can improve some traditional finishing practices.
As a kind of construction glue, 107 glue plays a role in the preparation of paint putty and concrete mixing process. It can effectively improve the viscosity of concrete and play a bonding and transitional role between the base layer and the paint; 107 glue can replace Animal and plant glues are used, and when the wallpaper is pasted, the bonding strength is high.
107 glue can maintain lasting elasticity within the temperature difference range of -60~220℃, and has excellent electrical properties, chemical stability, water resistance, weather resistance, etc. These unique properties make 107 glue widely used in joint filling construction, electronic product insulation, rubber and plastic product molding, etc. 107 glue is also the base material of room temperature vulcanized silicone rubber.
3. The main hazards of 107 glue
107 glue is a water-soluble adhesive prepared by neutralizing after the condensation reaction of polyvinyl alcohol aqueous solution and formaldehyde solution under the catalysis of hydrochloric acid, which contains Free formaldehyde basically exceeds the standard, seriously pollutes the environment, and is very harmful to health.
Solvent-based pressure-sensitive adhesives
Rubber-based or acrylic solvent-based pressure-sensitive adhesives use a large amount of toluene and other volatile organic solvents. The solvents evaporate and the smell is overflowing, which is both polluting and It damages the surrounding environment and harms human health.
4.Uses of 107 glue
1. Making interior walls: Base: 107 glue is directly mixed with 40% white cement and 60% talcum powder, and the appropriate amount of glue is used.
Surface: 107 glue is mixed directly with talcum powder. (It is best to add a mixture of cooked glue powder and water)
2. For exterior walls: 107 glue is directly mixed with 70% white cement and 30% talcum powder, and the appropriate amount of glue is used. 2. Introduction to 108 glue
1. Introduction to 108 glue
108 glue, also known as "polyvinyl formal glue", is made of polyvinyl alcohol and formaldehyde in an acidic medium. A polymer bonding solution obtained by condensation reaction, which is a translucent or transparent aqueous solution. It is odorless, tasteless, non-toxic, has good bonding properties, and the bonding strength can reach 0.9MPa. It can be stored for a long time at room temperature, but it is prone to gelation at low temperatures, and may become moldy and dirty if left under high temperature conditions for a long time. In addition to being used for wallpaper and wall coverings, polyvinyl formal glue can also be used as a configuration material for indoor and outdoor wall and floor coatings. Combined with gypsum powder or talcum powder to form a paste, it can be used for base treatment of indoor and outdoor walls. Adding 108 glue to ordinary cement mortar can increase the bonding force between the mortar and the base layer.
2.108 glue construction temperature
The construction environment temperature is above 5℃. The construction and maintenance temperature is above 0℃. 108 glue is stored and transported in a ventilated, light-proof and dry place with a room temperature not lower than 5°C. The shelf life is 12 months. The product is non-toxic and non-flammable, and storage and transportation can be handled in accordance with the "Non-Dangerous Goods Regulations".
3. Precautions for 108 glue
The quality of products produced by different manufacturers on the market is also different. If there is a particularly strong smell, it may be due to the addition of lower-cost harmful substances. It may turn black and smelly if left at room temperature for a period of time. This is a serious low-cost product that deceives consumers. It may contain substances such as starch or cellulose, so when purchasing Be sure to make detailed reference from the manufacturer, consumer reputation, etc.
4. The purpose of 108 glue
The base layer should be dense and free of floating dust. If the wall surface is loose or smooth, 108 glue needs to be used for interface treatment or cement roughening.
For ceramic tile treatment, soak the tiles in water for a few minutes and take them out to dry in the shade.
