rosin is an important chemical raw material, widely used in various industrial sectors, the main use is as follows:1.soap industryrosin 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 deterioration2.paper industrygum rosin used as a papermaking material in the paper industry. rosin and rosin sodium soap made from caustic soda, namely rubber, plastic materials mixed with the pulp and adding alum, rosin becomes stuck in a small water-insoluble fiber free resin acidparticles, 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, reducethe degree of expansion.3.paint and coatings industryrosin soluble in various organic solvents, and the film deposition, shiny, is one of the basic raw material of paint. the role ofrosin in the paint is to paint bright color, fast drying, smooth and easy to fall off the film4.ink industryrosin 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, blurred5.adhesives industrial rosin ester and hydrogenated rosin ester as a binder base material, commonly used as hot melt adhesives, pressure sensitiveadhesives and rubber tackifier6.rubber industryrosin used as a softener in the rubber industry, increase its flexibility. disproportionated rosin potassium soap can be used forsynthetic rubber7.food industryhydrogenated rosin esters and natural chicle, wax, vinyl acetate, etc. together with the melted, then add spices, sugar and mixthoroughly pigment can be made into gum. after the slaughter of pigs in the slaughterhouse, cattle, sheep, when, after hairremoval with mechanical operations, left in the animal body and head hair can be used by the 88-94% of molten rosin and 6-12% ofcottonseed oil consisting of depilatory to remove8.electrical industryrosin 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 mixed9.building materials industryrosin in the building materials industry mainly used as a foaming agent and a concrete floor tile adhesive. rosin is also used asvinyl asbestos tile adhesive. rosin and linseed oil, calcium carbonate, charcoal, pigments, etc. can be mixed together tomanufacture carpet tiles
