Shandong import PUR glue how much how much is the shandong import PUR glue melting point 124 ℃.
By the main body material to points: can be divided into polyethylene -
Vinyl acetate (
Class, polyamide hot-melt adhesive
Kind of hot melt adhesive, polyurethane (
Kind of hot melt adhesive, polyolefin (
Kind of hot melt adhesive, block copolymer (
Kind of hot melt adhesive, etc.
Soluble in water, its solubility in water.
In the process of printing, composite, the viscosity of control is the key, particularly in the 80 -
Output of 140 m/min high-speed gravure and compound, with the passage of the actual, the solvent in constant volatilization, viscosity also gradually rise, liquidity becomes poor.
Shape to the points: can be divided into hot melt colloidal particles, hot melt adhesive stick, hot melt adhesive, hot melt glue, hot melt glue powder, etc.
D, try to avoid long time use cleaning solvent cleaning pur moisture reactive hot melt adhesive machine work, so as to avoid inhaling too much because of potentially harmful gas under high temperature.
So thanks to the current development of science and technology brings us convenience.
To use points: can be divided into filter hot melt adhesive, automated packaging hot melt adhesive, car interior with hot melt adhesive, hot melt adhesive label, adhesive tape, hot melt glue, hot melt adhesive, etc.
In production, when printing, composite viscosity rise, are artificial with adding solvent to dilute viscosity kettle.
Other categories: whether reaction, color, whether natural, whether there is a pressure sensitive resistance, and so on.
Aviation industry 6 optical (
Adhesive lens element)
Hot melt adhesive application fields of shandong import PUR glue how much patent CN101432840 introduces a new type of pressure sensitive adhesive, on the basis of the original composition, plant polysaccharides and poly (amino acid modified nano the SiO as modified agent, amino acids and the SiO 2 amino on hydroxyl groups on the surface of the hydrogen bond formation, improves the steady 2 qualitative and dispersion.
Hot melt adhesive products have been applied to every aspect of people's life, people eat, wear, live, use, transportation, every field of play, eat a bowl of instant noodles, drink water, drink a cup of wine, wear clothes, shoes, hats, government buildings projects, live in a house, sit in the cars, trains, planes, refrigerators, color TV, washing machine, toilet paper, toothpaste, soap, beautify the living space crafts, decoration, craft flower, children's toys, gifts, etc. , are the application of hot melt adhesive.
Can say, in modern people's life, the application of hot melt adhesive is everywhere.
Used in the cages with fish, the road guardrail, basked themselves, rack, refrigerator insulation, fan cover, etc.
Epoxy adhesive is characterized by low thermal expansion coefficient, high Tg, good heat resistance, mainly used for assembly.
Add, the more printing color change after production, the greater the homogeneous degree of the composite is poorer, fastness also drops, thereby increasing the return and the rejection rate.
