Dongying HENKEL adhesive' target='_blank'>water-based adhesive contact dongying HENKEL water-based adhesive contact solids 50-2% of health and safety and 20 kg, 50 kg bottled product use machine good adaptability, high peel strength, good ink, 礚 powder capability is strong, the early stick with a viscous fluid, can replace the existing solvent laminating adhesive used on dry laminating machine look pale yellow viscous emulsion should stir well when using stored in shady and cool place, avoid direct sunlight, keep the temperature is 5 ~ 40 ℃ industry use of pressure-sensitive adhesive are mainly four categories: solvent-based emulsion pressure sensitive adhesive, pressure-sensitive adhesive, hot melt pressure sensitive adhesive and radiation type of pressure sensitive adhesive. 3 - curing speed 5 0 - 202, in to remove the maintenance work, maintenance personnel do not wear earrings, watches, necklaces, bracelets and so on can be conductive adornment, prevent accidents. Hot melt pressure sensitive adhesive due to solute ( Hot melt glue) Different kinds of solvent hot melt adhesive can be made of a variety of utility. Mainly used for women's sanitary napkin, diaper, bed pad, senile incontinence supplies such as shame. 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: dongying HENKEL water-based glue will contact the glue sample of small box put people keep the constant temperature incubator is 105 - 110 ℃, drying to constant weight, according to its quality, record values. 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. 8, the pur hot melt glue machine pressure plate after cleaned up, press the pressure plate shall be immediately into the new pur hot melt adhesive in barrel, avoid long time to get the pressure plate, exposed to air. Shape: white or light yellow block viscoelastic, solid; Dongying HENKEL water-based adhesive contact [ 3] The experiment reagent 4. Latex solid content first made a small box, aluminum foil with electronic analytical balance according to its quality, record the value. Has good initial moisture, transfer completely appearance slightly yellow latex coating after draping, drying temperature for 80 ~ 120 ℃, depending on the requirement of the product and the draping speed adjust packing and storage should pay attention to prevent frostbite, under 0 ℃ storage for a long time can damage performance is suitable for paper/plastic bag, plastic/plastic box, arms around the adhesive solids 50 + / - 1% ( 105℃±1. 5℃/ 3 h) The health and safety ( 2) Pressure sensitive adhesive the shape classification of this experiment adopts the polymerization, emulsion polymerization particle can be achieved by using the method better adhesive solution and fine quality. 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℃; Hot melt adhesive properties of 5, good quality hot melt adhesive with heat resistance performance, can put the hot melt adhesive in zero or more than 40 degrees respectively test environment, if there are brittle, soft gelatin said quality is bad now. Thermal decomposition of the initiator for when heated has triggered active free radicals can break down the material, a general by the initiator molecules are split into two free radicals, such as persulfate little in alkaline, neutral or acidic solution to thermal decomposition process is as follows: the performance test of adhesive strength: 2. 0 - 2. 51g/25mm; Health requirements: tasteless, non-toxic, do not stimulate the skin. Dongying HENKEL water-based adhesive contact because of 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.
