Introduction of hot melt coating machine:
彩翼无遮挡漫画1, hot melt coating machine is a kind of solid to solvent, water content, 100% soluble polymer, solid at room temperature, heating and melting to a certain extent to flow and viscous liquid adhesive, coating on the substrate, usually contains a composite part of the a substrate and a coating substrate composite with equipment.
2, the process has the advantages that do not need drying equipment, low energy consumption: no solvent (hot melt adhesive for 100% solids) no pollution, not because of the excess glue cleaning workers and exposed to a large number of formaldehyde. With solvent and water soluble adhesive under the traditional Arabia digital contact professional manufacturer of hot melt coating machine coating process compared with enviable advantage, effectively solves the shortcomings inherent in the traditional process, is an ideal production tool coating compound renewal industry.
彩翼无遮挡漫画3, solvent and adhesive curing agent to the oven (or may need to be renovated, and the existing oven) take more plant space, while increasing the plant energy consumption; more waste water and sludge; production and operation requirements are more stringent; glue drawback is obvious, is not very friendly (most harmful solvents). The environmental pollution of solvent based adhesives is very serious. With the improvement of people's environmental awareness and the establishment and improvement of relevant laws, the application of solvent based adhesives is declining at a certain speed every year. The water gum has disadvantages poor water resistance and electrical characteristics of bad, long drying time, high energy consumption, it is also used every year to a certain rate of decline. Hot melt adhesive has the advantages of stable performance, high utilization rate of raw materials, high production rate, high yield, small footprint and small investment.
4, hot melt adhesive:
The main component of hot melt adhesive, namely basic resin and vinyl acetate copolymer under high pressure and with thickening agent, viscosity regulator, antioxidant and so made of hot melt adhesive.
1) at room temperature is usually a solid, heated to a certain degree of melting into a liquid once cooled to the melting point, and quickly become a solid.
彩翼无遮挡漫画2) with fast curing, low pollution, strong adhesion, adhesive layer has some flexibility, hardness and certain toughness; 3) glue solidification layer glued on, can also be heated and melted
彩翼无遮挡漫画4, and then changed into a paste and then adhered to the adhesive, with a certain degree of re adhesion;
5) when in use, as long as the hot melt heating melt into a liquid required, and apply in the glued object,
6) after the pressure in a few seconds to complete the bond curing, within a few minutes to achieve the degree of hardening cooling drying.
彩翼无遮挡漫画7, because of its products are solid, easy packaging, transportation, storage;
8) no solvent, no pollution, non-toxic;
9, and the production process is simple, high added value, viscosity and strength, speed and other advantages and favored. 10 hot melt adhesive with stable performance, high utilization of raw materials, production speed, high yield
11) the equipment has the advantages of small occupation area and small investment.
