Lijiang lijiang sealing glue factory authorized sealing glue factory 3, checking and adjusting pur don't remove the moisture reactive polyurethane hot melt adhesive any parts of the machine unless you have enough knowledge of equipment performance. Join the right amount of antioxidants to prevent premature aging of EVA hot melt adhesive. Because colloid when molten high temperature oxidation decomposition, adding antioxidants can guarantee under the condition of high temperature, bonding performance does not change. Functional monomer is acrylic acid, acrylamide, maleic anhydride monomer, such as they join the introduction of polar groups in the middle of the copolymer, the electronic effect of polar group enhanced the copolymer and the polarity by bonding surface bonding of sex. In addition to the above several kinds of raw materials can also be according to the difference of temperature, regions with some suitable for cold with the temperature of the thermal dose of cold resistance agent or suitable for tropical temperatures. ( 2] ( 6] Product features look pale yellow viscous emulsion used to maintain good health can be divided into solvent pressure sensitive adhesive, pressure-sensitive adhesive water solution type pressure sensitive adhesive and emulsion pressure sensitive adhesive, hot melt pressure sensitive adhesive and rolling pressure sensitive adhesive, etc. Five types. Defect is poor film-forming, washing fastness, PU can't stick hot glue. Authorized sealing glue factory 9, product selection of lijiang in the pur hot melt glue machine press pressure plate into the plastic bucket, can be appropriate in the daub on the seal of the pressure plate do a small amount of silicone oil lubrication, lubrication, between the pressure plate and rubber barrel to protect the use of the seal ring. Water soluble with its functional and environmental protection, and the price is low, will be the future direction of coating. A, the color of the glue is supposed to have the difference. If being itself to the color no special requirements, then it is recommended to use yellow hot melt adhesive, generally speaking, yellow hot melt adhesive is better than white sticky. Lijiang authorization sealing glue factory smell is the inherent nature of the material, is one of the important features, material can be measured. Second, by then surface treatment. Hot melt adhesive surface treatment to be then there is no other adhesive is so strict, but was then content on the surface of the dust, oil pollution also should do the appropriate processing, hot melt adhesive can give full play to the functions of glue. Lijiang authorization (4) from the cleaning fluid sealing glue factory plastic brush, must use clean cloth to wipe dry rear can be used to besmear to brush glue; Hard monomers such as methyl methacrylate, these homopolymer Tg is higher, can enhance the cohesion strength of pressure sensitive adhesive, with the increase of the hard monomers, the viscosity increase of the pressure sensitive adhesive peel strength increases, the early viscous force will be reduced. According to the provisions of GB/T 2792. Three, homework time. Homework is an important characteristic of hot melt adhesive quickly. Hot melt adhesive homework time generally in 15 seconds, with modern production mode - - Assembly line is widely used, shorter operation time requirements for hot melt adhesive, such as books binding and speaker manufacturing of hot melt adhesive work time requirements for 5 seconds. Lijiang authorization sealing glue factory this kind of adhesive if it is for ordinary families, the quality is not important. Lijiang authorization sealing glue factory clothing with poly phthalein amine hot melt adhesive machine reference formula for quality of nylon 100 salt, 85 quality of nylon 6 a 'salt, 150 quality of nylon 1010 salt. Usually volatile substances smell, the smell of heavy metals and other inorganic small.
