Hebei import sealing glue equipment imported sealing rubber hebei again into the glue in a small box in the sample, according to its quality, record the value. 3 - curing speed 5 0 - 204, the smell of the customer product source: (1) using water-based glue, conform to the shoe industry, a long-term trend in brands actively, adhesive' target='_blank'>water-based adhesive has been widely used all kinds of shoe factory, water-based glue quality gradually progress and stability; Today before each add glue to the bowl, should finish the previous glue used; (2) use water-based glue will lead to environmental protection, health, save energy, save cost of equipment and manpower, fire safety, etc; Search the public number: WPU - 88 China adhesive platform 8 pet-name ruby besmear to brush the glue specification, according to besmear brushs mark line, besmear to brush besmear to brush back and forth at least once, for some more material to glue ( Such as more than fluff flannelette, after grinding coarse leather, etc. ) Besmear to brush back and forth is particularly important to ensure that the coating in place, at the same time should also prevent the rubber product; In the 1970 s, the low glass transition temperature of poly (acrylic acid esters, such as poly (butyl acrylate as the glass transition temperature ( Tg) Is low, and endowed with pressure sensitive adhesive inherent viscosity, don't need to add extra viscosity resin, reason often is used for the preparation of solution or emulsion pressure sensitive adhesive. Hot melt pressure sensitive adhesive is mainly used for women's sanitary napkin, diaper, bed pad, senile incontinence supplies etc. Especially the latter, along with our country aging of population structure. The next older incontinence supplies will increase rapidly. The use of hot melt adhesive technical indicators are as follows: hebei import rubber sealing equipment due to the low glass transition temperature of homopolymer ( Tg:- 20 - — - 700 c) Viscosity, usually by the function of flexible monomer is given priority to, add high glass transition temperature, can be given adhesiveness and cohesion as hard monomer, and a small amount of monomer copolymer containing functional groups. Because of the solute ( Hot melt glue) Different kinds of solvent hot melt adhesive can be made of a variety of utility. Shape: white or light yellow block viscoelastic, solid; Hebei import stickers glue sealing glue equipment appearance white or light yellow emulsion used to maintain good health stored in shady and cool place, avoid direct sunlight, keep temperature is 5 ~ 40 ℃ is suitable for BOPP film/printing, PET laser machine/products combined with good gloss, good heat resistance and freeze resistance, corrosion resistance strong viscosity pa 10000 ~ 30000. S antifreeze should be paid attention to the health and safety, under 0 ℃ storage for a long time can damage performance acrylate pressure-sensitive adhesive is second only to the rubber type, with much pressure sensitive adhesive, it is a copolymer of acrylic ester monomer and other vinyl monomers, which can be roughly divided into crosslinked type and the crosslinking type two kinds. 2, in to remove the maintenance work, maintenance personnel do not wear earrings, watches, necklaces, bracelets and so on can be conductive adornment, prevent accidents. 2, don't in the absence of appropriate protective device, and a good insulator or good protection panel under the operation of using hot melt adhesive machine. Melting point: 80 90℃; Multi-purpose solvent hot melt adhesive in the production of many products, such as: thermal transfer printing, sealing liquid crystal materials, wallpaper anti-counterfeiting grade, calligraphy and painting paper, computer printing, food, wire and cable production date type code is the performance of the application of hot melt adhesive, but cannot use the existing granule or powder form, not in the presence of suitable solvent, a liquid prepared by coating on a substrate, get a thin and uniform film may be used in process after the production. Hebei import rubber sealing device 7, if possible, try to stand in plastic carpet for maintenance work. When used on clothing, get cool, hot melt adhesive machine is mainly made from rubber powder, poly acid amine to further manufacture of resin lining.
