Rosin is an important chemical raw material, widely used in various industrial sectors, the main use is as follows: 1, soap and soda ash or caustic industrial rosin cooking together form a rosin soap. Rosin soap has great detergency, soluble in water, can dissolve fat, easy to play bubble. Rosin sticky, easy to crack and make soap rancidity deterioration. 2, the paper industry in the paper industry as rosin sizing papermaking. Rosin and rosin sodium soap made of caustic soda, i.e., rubber, plastic material mixed with the pulp and adding alum, rosin becomes stuck in a small water-insoluble fiber free resin acid particles, when the pulp is heated in the drying cylinder rolling when filling in between the fibers soften rosin, this effect is called "glue" or "glue." After the paper "glue" to enhance water resistance, to prevent ink penetration, improve the strength and smoothness, reduce the degree of stretching. 3, paint industry Rosin soluble in various organic solvents, and easy film, glossy, is one of the basic raw material of paint. The role of rosin in the paint so that the paint color is bright, fast drying, easy to fall off the film is smooth. 4, the ink in the printing ink industry Rosin is mainly used as chromophores, and enhance the adhesion of ink to the paper. If you do not have rosin ink, printing ink will become dull tone, blurred. 5, the adhesives industry rosin ester and hydrogenated rosin ester as a binder of the basic raw material, is often used as hot melt adhesives, pressure sensitive adhesives and rubber tackifier. 6, rubber industry rosin used as softeners in the rubber industry, increase its flexibility. Disproportionated rosin potassium soap can be used for 7, building materials industry Rosin is mainly used in the building materials industry to make concrete foaming agent and a floor tile adhesive. Rosin is also used vinyl asbestos tile adhesive. Rosin and linseed oil, calcium carbonate, charcoal, pigments, etc. can be mixed together to manufacture carpet tiles. |
