Zhoushan Germany food-grade plastic dealers zhoushan Germany food-grade plastic dealers colorless or pale yellow oily liquid, dissolved in water is transparent. Pva water-based adhesive, vinyl acetate, water-based adhesive, acrylic water-based adhesive, polyurethane water-based adhesive, water-based adhesive, water-based phenolic epoxy adhesive, organic silicon water-based adhesive, rubber water-based adhesive. Zhoushan German food grade glue dealers so using pur polyurethane hot melt adhesive machine should be safe at all times. 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. 2. According to the application of classification: but by crosslinking and use measures such as protective agent, can make its weather resistance and heat resistance improved. Packaging used in water-based adhesive, water-based adhesive, car use water-based adhesive, shoes, daily use water-based adhesives, water-based adhesive zhoushan German food grade glue distributor if seriously, or by hot melt adhesive to the area wide, may cause casualties or injuries place can have the trend of inflammation, you must keep the injured body temperature in normal condition, and then immediately sent the injured to hospital. Because of the gluing device efficiency and the difference on the production process, especially after the glue adhesive is not the same time, lead to hot melt adhesive manufacturer not only the development of a product can meet the need of all kinds of adhesive. 3. According to the classification of solvent properties of water-soluble and emulsion adhesives and a variety of usage of modified hot melt adhesive, the life of a hidden artifact hangers skid would clothes? Phone line fault is not willing to throw? The blade naked too? The closet door shutting too big? Now the life need a glue gun can be all done! Don't let hot melt glue gun idle, let it go and live to Duan Junzi glue. (5) the good glue application bowls costumes and cover; 7 after pressing shoes again in a short period of time to put in the oven baked does also leads to glue; 6. According to the weight of the brackets than add hardener ( 100:5) ; Water-based adhesive and the demands in many early adhesive application areas are very urgent, such as: 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. 1, water-borne polyurethane ( APU) Adhesive APU is water instead of organic solvent as a new type of polyurethane dispersion medium system, also known as polyurethane or water-based polyurethane water dispersion of polyurethane, river systems. Waterborne polyurethane with water as solvent, no pollution, safe and reliable, excellent mechanical properties, good compatibility, easy modification. Zhoushan German food grade glue dealers simply join reactive flame retardant monomer gives acrylate pressure-sensitive adhesive permanent flame retardancy. 2 acrylic ester copolymer emulsion with monomer is usually divided into three classes: polyvinyl alcohol: structured - CH2CH( 哦) ] n -; Polyvinyl alcohol is a kind of not monomer polymerization and water-soluble polymer is obtained by polyvinyl acetate hydrolysis, referred to as '. 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. The APU adhesive non-toxic pollution-free, high molecular weight so that it can form good performance of the adhesive film, it has good low temperature resistance, good flexibility, adhesive ability and the advantages of wide range of physical properties of the film can be adjusted; Flexible chain, has in its molecular structure shows good impact resistance, fatigue resistance, low temperature resistance, also has the design, the performance of rubber from the flexible and rigid arbitrary adjustable, can meet the demand of adhesion between different materials; Is comparatively mature methods for the preparation of aqueous polyurethane adhesives, mainly has the following several ways: zhoushan Germany food-grade plastic dealers its main drawback is that there are unsaturated double bonds in molecules, poor light and oxygen aging resistance. Zhoushan German food grade glue dealers to acid and alkali resistance. If the gluing equipment craft is not normal operation mechanism, it on the market it is difficult to find the corresponding use hot melt adhesive.
