Chinese hot melt glue stick extruder industry is developing rapidly

Hot-melt adhesive is an environmentally-friendly and organic adhesive. It has a strong adhesiveness and a short cooling time. It has gradually replaced the cold glue such as white plastic yellow rubber. It is a rubber that has increased in demand in China and the world in recent years, and hot melt glue sticks are squeezed. Out of the machine is one of the main equipment for the manufacture of hot melt adhesives.

From the late 1970s, hot melt adhesives began to enter the wood industry for edge sealing, plywood core, panel splicing, furniture splicing, etc. Early hot melt adhesive equipment relied mainly on the United States, West Germany, Italy and other countries. Equipment, with the maturity and stability of China's hot melt adhesive equipment, the selection and use of hot melt adhesive equipment suitable for the specific conditions of each furniture factory can not only improve the quality and grade of furniture, but also improve production efficiency and reduce plate repair. The difficulty of reducing the labor intensity of workers.

Hot melt adhesive for furniture is a kind of adhesive specially used for the bonding of artificial boards. It is an environmentally friendly, solvent-free thermoplastic adhesive. When the hot melt adhesive is heated to a certain temperature, that is, from a solid state to a molten state, when applied to the surface of the artificial board substrate or the edge sealing material, it is cooled to a solid state, and the material is bonded to the substrate.

Its characteristics are:

   1. The solid content is 100%, and there is void filling property, which avoids the defects such as deformation, dislocation and shrinkage of the adherend due to edge rolling, air bubbles and cracking. Because there is no solvent, the moisture content of the wood does not change and there is no danger of fire and poisoning.

   2. Fast bonding, glue and bonding interval is only a few seconds, saw head and trimming can be completed in 24 seconds, no drying time is required, can be used for continuous and automated wood bonding line, greatly improving production Efficiency, saving plant costs.

   3. Wide application, suitable for bonding various materials.

   4. It is possible to perform several bonding, that is, hot-melt adhesive coated on wood. If it is not cooled by curing, it can be reheated for secondary bonding.
