Sanming henkel PUR adhesive agent in sanming henkel PUR adhesive agent used by the tool before drying of glue can be used warm water to clean. Due to the particularity of pur polyurethane hot melt adhesive machine, also known as wet pur polyurethane hot melt adhesive curing reactive polyurethane hot melt adhesive, also known as wet cause sclerosis of reactive polyurethane hot melt adhesive, hereinafter referred to as pur hot melt adhesive, when used in hot melt such as contact with the water vapor in the air from curing reaction, therefore with pur hot melt adhesive machine need to air in the process of melting and the use of total isolation, pur hot melt adhesive machine is specially designed for polyurethane hot melt adhesive glue. You may need to know about pur polyurethane hot melt adhesive machine. After understanding the characteristics of the pur polyurethane hot melt adhesive, to understand the following maintenance is easy. Colorless or pale yellow oily liquid, dissolved in water is transparent. 4, ensure the pur hot melt adhesive machine operation under the specified voltage, if used by power supply voltage is different from the specified standards, may be the cause of hot melt adhesive machine was burned down. Sanming henkel PUR adhesive agent regenerated rubber, especially made from renewable natural rubber pressure-sensitive adhesive has good performance, the price is cheap, and therefore be taken seriously. 6, if the temperature is too low will cause the glue is not completely dry and prone to bad 'cohesion' wait for a phenomenon, or could be well at the time, but for a long time will still be 'drawing' and 'bad viscous force'; Repair glue is also called the repair glue, mainly applied in the metal, ceramic materials such as mending adhesive effect, common application for casting repair, can satisfy the requirements on the mechanical properties of the normal after repair. C, before using cleaning solvents, must check whether indoor air liquidity is good, avoid to use open flame, not under the environment of air does not flow cleaning pur hot melt adhesive machine. Sanming henkel PUR adhesive agent due to different flame retardants and the compatibility of acrylic pressure sensitive adhesive, the flame retardant effect can make a big different. 1. Four characteristics of the hot melt adhesive curing speed, curing several seconds, cooling heating molten, sticky characteristics, facilitate continuous, automatic high-speed operation, improved the production efficiency and reduces the cost; Solids and contains no solvents, non-toxic environmental protection, energy saving, won't produce secondary pollution to the environment; Non reactive hot melt adhesive can be repeatedly melt adhesive, especially suitable for some special technical requirements of component adhesive, as some of the cultural relics repair; Three, pur hot melt glue machine for rubber considerations: 1, the installation and use of pur hot melt adhesive machine, other debris must not be placed on the body or used as padding instruments. In recent years, domestic demand for acrylic pressure sensitive adhesive is bigger and bigger, and strict in the flame retardant performance in particular areas. This is to develop early, since production is still a lot of kind of rubber pressure-sensitive adhesive. They are natural rubber elastomer as the main body, cooperate with viscosity-enhancing resin, softening agent, stabilizer, fillers and crosslinking ( Sulfide) Agent such as the complex mixture of additives, due to the natural rubber has both high cohesion strength and elasticity, and can very good miscibility with many viscosity resin, get high viscosity and good wettability of glued materials, so the natural rubber is ideal type of pressure sensitive adhesive main body material. Its main drawback is that there are unsaturated double bonds in molecules, poor light and oxygen aging resistance. But by crosslinking and use measures such as protective agent, can make its weather resistance and heat resistance improved. Made from natural rubber pressure-sensitive adhesive can almost all kinds of pressure sensitive adhesive products. Sanming henkel PUR adhesive agent for the commercial clean, wet cloth on the parts. Sanming henkel PUR adhesive agent in rubber components, from a single polyisobutylene gradually become styrene thermoplastic elastomer, improves the cohesive strength of the film; On the structure by 1 layer structure into a 2 layer structure, layer 2 components are different, different, increasing the service efficiency of pressure sensitive adhesive. So using pur polyurethane hot melt adhesive machine should be safe at all times.
The use and installation of chemical company is compared with most other systems for managing the chemical factory effectively and no doubt chemical company have won the race so many times.
As manufacturers we are determined to be the very best in chemical company, regardless of the size, pedigree or inclinations of our competitors.
