Rosin resin is a important raw material, widely used in different industrial field, main useage is as below:

1. Soap industry
Rosin is cooked with soda or caustic soda to form rosin soap. Rosin soap has a great detergency, is easily soluble in water, can dissolve oils, and is prone to foaming. Rosin is sticky, making the soap less susceptible to cracking and spoilage.

2. Paper industry
Rosin is used as a papermaking compound in the paper industry. Rosin and caustic soda made of rosin sodium soap, that is, rubber, rubber compound mixed with pulp and added alum, so that rosin become insoluble free resin acid particles attached to the small fibers, when the pulp in the drying cylinder rolling heating At the time, the rosin softens and fills in between the fibers. This action is called "gluing" or "sizing". After the paper is "glued", it can enhance water resistance, prevent ink penetration, improve strength and smoothness, and reduce the degree of stretching.

3. Paint and coating industry
Rosin is easily soluble in various organic solvents, and its film-forming film is glossy. It is one of the basic raw materials for paint coatings. The role of rosin in the paint is to make the paint bright and bright, dry quickly, the paint film is not easy to fall off.

4. Ink industry
Rosin is mainly used as a chromophore in printing inks and enhances the adhesion of ink to paper. If rosin is not used in the ink, the printed ink will be dull and unclear.

5. Adhesive industry
Adhesives based on rosin esters and hydrogenated rosin esters are commonly used as hot melt adhesives, pressure sensitive adhesives, and rubber tackifiers.

6. 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.

7. Food industry
Hydrogenated rosin glycerides are heated and melted with natural chicle, Wax, vinyl acetate, etc., and then blended with spices, sugar, and pigments to make chewing gum. When pigs, cattle, and sheep are slaughtered in a slaughterhouse, the hairs left in the animals' bodies and heads can be depilated with 88-94% of melted rosin and 6-12% of cottonseed oil after the hair removal machine is operated. To remove.

8. Electric industry
The use of rosin 35% and 65% bright oil as insulating oil on the cable used as a protective film, insulation and heat resistance. Rosin is used as an insulating varnish in combination with bakelite and other synthetic resins.

9. Building materials industry
Rosin is mainly used as a concrete foaming agent and a floor tile binder in the building materials industry. Rosin is also used as a binder for vinyl chloride asbestos tiles. Rosin and linseed oil, calcium carbonate, charcoal, pigments, etc. are mixed together to make tile tiles.

10. Make a drawing liquid
Due to its solubility, volatility, and the ability to quickly condense into a “solid and transparent film” principle after evaporation, the artist protects the picture and prevents the “drawing” from being knocked out. Usually, the artist creates “draw” liquids by himself. : A portion of rosin powder, nine parts alcohol, or xylene solvent. Place the rosin in a well-sealed glassware. Pour the alcohol, or xylene, into the lid. Cover it and dissolve it after two days. When used, shake it and pour it into the watering can, 20 centimeters away from the screen, evenly sprayed on the screen, spray at any time, evaporate at any time, and after a few minutes, it will dry out. After that, it will not be afraid of being knocked out. Note: Rosin can not be more, more will be "yellow, dark!"
