Introduction of wood glue:
Wood glue, also known as white latex, is one of the water-soluble adhesives that are widely used, used in large quantities, and have a long history. It is a thermoplastic adhesive polymerized by vinyl acetate monomer under the action of an initiator. It can be cured at room temperature, with fast curing speed, high bonding strength, good toughness and durability of the bonding layer, and is not easy to age. It is widely used in wood, furniture, decoration, printing, textile, Leather, paper and other industries have become familiar adhesives.

Performance characteristics of wood glue:
1. Woodworking glue has a series of advantages such as room temperature curing, fast curing speed, high bonding strength, good toughness and durability of the adhesive layer, and not easy to age. It can be widely used for bonding paper products (wallpaper), and can also be used as a waterproof coating and adhesive for wood.
2. It uses water as a dispersant, safe to use, non-toxic, non-flammable, easy to clean, cured at room temperature, good adhesion to wood, paper, and fabrics, and high bonding strength.
3. The glue layer after curing of wood glue is colorless and transparent, has good toughness, does not pollute the adherend, and is easy to process.
4. The emulsion has good stability, and the storage period can reach more than half a year. Therefore, it can be widely used in printing and binding, furniture manufacturing, bonding of paper, wood, cloth, leather, ceramics, etc.
The use of wood glue:
1. The moisture content of wood should be controlled at 8-15%. Too high or too low will affect the bonding quality.
2. Use wood glue to treat the surface of the base material so that it is free from oil, dust and other impurities. Adhesive surfaces must be in full contact.
3. Apply glue evenly and properly.
4. Wood glue can be cured at room temperature or heated. The temperature should not exceed 120. The curing time varies with the temperature and can be determined according to the actual situation.
5. When pressurizing, the pressure should be sufficient and uniform. It should be pressurized for more than 1.5 hours, and it should be kept for a period of time after the pressure is released. In order to achieve a better bonding effect, the pressure should be released, placed for 24 hours before processing, and tested for 72 hours.
6. Wood glue can be mixed with certain resins, such as urea-formaldehyde resin, phenolic resin, melamine resin, etc. To improve its water resistance and creep resistance.
