Shijiazhuang specialty sealing glue direct shijiazhuang sealing glue direct selling 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. 3 - curing speed 5 0 - Viscous force, transfer completely in the early 20th with good appearance slightly yellow latex coating after draping, drying temperature for 80 ~ 120 ℃, depending on the requirement of the product and the speed combined with appropriate adjustments should be paid attention to packaging and storage anti-freeze, 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. Hot melt pressure sensitive adhesive 2, dismounting in maintenance work, maintenance personnel do not wear earrings, watches, necklaces, bracelets and so on can be conductive adornment, prevent accidents. 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: shijiazhuang professional sealing glue direct marketing according to the provisions of GB/T 2793. To press the hot plate into plastic barrels, size of lifting cylinder pressure should be from small to large, may not directly use the high pressure gas, prevent accidents, pay attention to the safety of the operator. 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; Shijiazhuang professional sealing glue outlet due to solute ( Hot melt glue) Different kinds of solvent hot melt adhesive can be made of a variety of utility. 7, if possible, try to stand in plastic carpet for maintenance work. Melting point: 80 90℃; 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. Shijiazhuang professional sealing glue direct thermal decomposition of 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.
