RF polymer welder.How much is the hot melt adhesive laminating machine?

　　The development of hot melt adhesive laminating machines in recent years is evident to all, and their performance in many fields is also quite objective. The market prospects are definitely optimistic. During the coating process of the hot melt adhesive laminating machine, in order to make the coating uniform, the viscosity that is easy to apply is adjusted and controlled by adding organic solvents.

　　The coating system of the solvent-free laminating machine introduced by China's hot melt adhesive laminating machine now has a significant difference in molecular weight between solvent-free and solvent-containing systems. The molecular weight of solvent polyurethane adhesives is generally between tens of thousands and hundreds of thousands. When there is no solvent, the viscosity is also very high, reaching millions of millipascals per second (mpas) at room temperature, and even in the form of a gel, which cannot be directly coated. So with the help of solvent dissolution and dilution, the viscosity can be coated. Technology is constantly being updated, and its scope of use in various fields is also becoming wider. The processing technology is becoming more and more obvious, and it is gradually being recognized and accepted domestically.

　　The hot melt adhesive laminating machine is easy to operate, reliable and fast in bonding, with high processing efficiency, uniform coating and low adhesive consumption, which does not pollute the environment and meets current environmental protection requirements. Therefore, it is increasingly selected as a supporting production equipment in industries such as shoes, packaging, leather goods, paper boxes, accessories, building materials, sports equipment, sanitary products, toys, electronics, appliances, leather, furniture, etc.
