This product is a important raw material, widely used in different industrial field, main useage is as below:
1. Soap industry It is cooked with soda or caustic soda to form soap, which has a great detergency, is easily soluble in water, can dissolve oils, and is prone to foaming.
2. Paper industry It is used as a papermaking compound in the paper industry. This product and caustic soda to make soap, that is, rubber, rubber compound mixed with pulp and added alum, so that it becomes insoluble free resin acid particles attached to the small fibers, when the pulp in the drying cylinder rolling heating
3. Paint and coating industry It 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.
4. Ink industry It is mainly used as a chromophore in printing inks and enhances the adhesion of ink to paper. If it 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 It 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.
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.
9. Building materials industry It is mainly used as a concrete foaming agent and a floor tile binder in the building materials industry.
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.
