The main uses are as follows:
Soap industry
Rosin is steamed with soda ash or caustic soda -to form rosin soap. Rosin soap has great deterring power, soluble in water, can dissolve grease, easy to foam. Rosin is sticky and makes the soap less prone to cracking and rackness.
Paper industry
Rosin is used as a paper binder in the paper industry. Rosin and caustic soda- to make rosin sodium soap, that is, glue, glue and pulp mixed and added alum, so that rosin into water insoluble free resin acid particles attached to small fibers, when the pulp is rolled on the drying cylinder heating, rosin softening and filling between the fibers, this effect is called "gluing" or "sizing". After the paper is "glued", it can enhance water resistance, prevent ink penetration, improve strength and smoothness, and reduce scalability.
Paint and coating industry
Rosin is easily soluble in various organic solvents, and easy to form a film, shiny, is one of the basic raw materials of paint coatings. The function of rosin in the paint is to make the color of the paint bright, dry quickly, and the paint film smooth and not easy to fall off.
Adhesive industry
Adhesives based on rosin esters and hydrogenated rosin esters are commonly used as hot melt adhesives, pressure sensitive adhesives and rubber viscosifiers.
Rubber industry
Rosin is used as a softener in the rubber industry to increase its elasticity. Disproportionated rosin potassium soap can be used as synthetic rubber.
Food industry
Hydrogenated rosin glyceride and natural gum gum, wax, vinyl acetate-, etc. are heated and melted together, and then mixed with spices, granulated sugar and coloring, etc., gum can be made. When slaughtering pigs, cattle, and sheep in a slaughterhouse, the hair left on the animal's body and head can be removed by a dehairing agent consisting of 88-94% fused rosin and 6-12% cottonseed oil after being operated with a dehairing machine.
Building materials industry
Rosin is mainly used in the building materials industry as a concrete foaming agent and a floor tile binder. Rosin is also used as a binder for vinyl chloride- asbestos tiles. Rosin and linseed oil, calcium carbate, charcoal, pigment, etc. can be mixed together to make carpet tiles.
