Sichuan specialty how much pressure sensitive adhesive
sichuan nD how much pressure sensitive adhesive refractive index (
1) water-based glue with water as solvent, drying process, there will be no VOC emissions, thus water-based glue is environmental friendly products;
Because do not use organic solvent, and because the range of the cost of crude oil prices rise is much smaller than solvent-based adhesive, relative to the solvent adhesive, water-based adhesive
has cost advantage;
Drinks with polyester bottle base, cans are available adhesive bonding.
(2) the initial force: water-based glue with water as solvent, the adhesive must be in the water fully evaporated, the resin particles together, each other can be reflected, the slower performance in solvent adhesive viscosity, thus early water-based adhesive force are usually more weak than solvent-based adhesive;
Because the latter water resistant, stand out from ice library condensation of moisture in the air erosion and long-distance transport across the environment even more.
(3) : late because of the small water molecules than solvent-based adhesive, can penetrate into the surface of the material smaller pore, equivalent to cast anchor in the material surface, its late on and solvent adhesive, with some suitable for cast anchor porous materials, such as mesh cloth and EVA, the late strength is better than solvent-based adhesive;
So the adhesive must meet the above requirements: such as corrugated cardboard, paper bags, cartons, paper tube and paper cups and other kinds of paper production adopts starch, modified starch adhesive, high quality cardboard and paper container are made from polyvinyl acetate thin homopolymerization or copolymerization adhesive and hot melt adhesive.
Three water-based glue suitable shoes and shoe type relative density 1.
Common material in: (1) the bottom of the PU, TPU, rubber, EVA, nylon, leather, artificial leather, you can use water-based glue;
Melting point -
Melting point: 70
(2) high oil content,> 15%)
The outermost layer of skin, prevent water splashing of the processed material and some bounce big hard material, we do not recommend using water-based glue;

The solar cell;
(3) paste, and glue (
Offices, schools and libraries use)
A, using solvent cleaning heating with viscose element, never use the fireworks or no temperature control of heating equipment cleaning, general pur moisture reactive polyurethane hot melt adhesive machine can't operate 280 degrees when cleaning and maintenance.
(3) for some sports strength of the body, such as football shoes, also use water-based glue is not recommended.
Sichuan professional how much pressure sensitive adhesive and the relevant domestic raw materials manufacturers should also recognize the development potential of the hot melt adhesive industry, increase the localization rate of raw materials, reduce the loss of foreign exchange caused by a large number of imported raw materials.
