Rosin is an important chemical raw material, widely used in various industrial sectors, the main use is as follows:
1.Soap industry
Rosin and caustic/soda or cooking together form a rosin soap. Rosin soap has great detergency, soluble in water, can dissolve fat, easy to foam. Rosin sticky, not easy to crack and make soap rancidity deterioration
2.Paper industry
Gum rosin used as a papermaking material in the paper industry. Rosin and rosin sodium soap made from, namely rubber, plastic materials mixed with the pulp and adding alum, rosin becomes stuck in a small water-insoluble fiber free resin acid particles, when heated on a roll pulp drying cylinder when filled between the fibers soften rosin, this effect is called "glue" or "glue." After the paper "glue" can enhance water resistance, prevent ink penetration, improve the strength and smoothness, reduce the degree of expansion.
3.Paint and coatings industry
Rosin soluble in various organic solvents, and the film deposition, shiny, is one of the basic raw material of paint. The role of rosin in the paint is to paint bright color, fast drying, smooth and easy to fall off the film
4.Ink industry
Rosin is mainly used in printing ink vehicle body and enhance the adhesion of the ink to the paper. If you do not have rosin ink, the ink will be printed into the dull hue, blurred
5.Adhesives industrial
Rosin ester and hydrogenated rosin ester as a binder base material, commonly used as hot melt adhesives, pressure sensitive adhesives and rubber tackifier
6.Rubber industry
Rosin used as a softener in the rubber industry, increase its flexibility. Disproportionated rosin potassium soap can be used for synthetic rubber
7.Food industry
Hydrogenated rosin esters and natural chicle, wax, etc. together with the melted, then add spices, sugar and mix thoroughly pigment can be made into gum. After the slaughter of pigs in the slaughterhouse, cattle, sheep, when, after hair removal with mechanical operations, left in the animal body and head hair can be used by the 88-94% of molten rosin and 6-12% of cottonseed oil consisting of depilatory to remove
8.Electrical industry
Rosin 35% and 65% light oil formulated as insulating oil in the cable used as a protective film for insulation and heat effect. Rosin and bakelite and other artificial resins used as the insulating varnish mixed
9.Building materials industry
Rosin in the building materials industry mainly used as a foaming agent and a concrete floor tile adhesive. Rosin is also used as vinyl asbestos tile adhesive. Rosin and linseed oil, calcium carbonate, charcoal, pigments, etc. can be mixed together to manufacture carpet tiles
