- With the improvement of consumers' requirements for appearance aesthetics and the continuous development of technology, the home appliance industry has adopted more elegant and easy-to-clean glass panels as external assemblies, such as refrigerators, washing machines, microwave ovens and other home appliances. The assembly and bonding of glass panels has become an important part of its production.
In the traditional assembly method of components in the home appliance industry, pressure-sensitive adhesive tapes such as 3M tape are generally used to complete the assembly, but problems such as loss of adhesion, virtual adhesion, poor sealing, and inability to achieve large-scale automatic assembly are often caused. Bonding and assembly methods and the realization of automated assembly processes are the requirements for assembly in the home appliance industry. The use of PUR hot melt adhesive effectively overcomes the defects of 3M tape itself, and solves the problems of loss of adhesion, virtual adhesion, poor sealing and automatic production.
The advantages of reactive hot melt adhesive used in home appliance assembly industry:
1. After the hot melt adhesive is heated, it is liquid and has fluidity, so it can effectively solve the tolerance of parts and avoid the phenomenon of virtual sticking;
2. High initial adhesion, high bonding strength, high and low temperature resistance, high humidity resistance, and long service life;
3. Excellent weather resistance, the reactive hot melt adhesive and the substrate can react with covalent bonds, so that the two substrates form a riveted whole, and the chain will not break within a certain temperature range. Therefore, the overall The bonding strength will not change with the temperature difference of four seasons.
4. Hot-melt adhesive inherits the inherent characteristics of hot-melt adhesive, meets the rapid assembly requirements of glass bonding, and better realizes different assembly processes and automated assembly.
