Application
For solder paste, welding aid mould, laundry soap, metal soap, varnish, printing ink, welding materials, insulation material, sizing agent for the paper and softener on increase rubber adhesive property,emulsifier for polymer polymerization, glue dosage and gum material, etc.
In Adhesive Industry:
Rubber based adhesive, synthetic resin based adhesive and vegetable adhesive all have rosin as one of their ingredients.
In the paint industry:
Rosin as a natural resin with abundant sources, is easily dried and smooth on its surface. It will continuously be the basic raw material for paint producing.
In printing ink industry:
rosin is mainly used as color carrier of the ink and to increase its adhesion to paper. Without rosin in the ink, the presswork
will be blurred.
In the Papermaking Industry:
Sizing agent made from rosin can prevent ink from dispersion, improve the strength and smoothness and enhance abrasion resistant
of the paper.
In the rubber industry:
rosin is used as a softening agent to make the rubber soft and easy for kneading, make the filling agent easily dispersed.
In the soap industry:
Rosin is boiled with soda or caustic soda to form loose soap.Loose soap has great detergency, is easily soluble in water, can dissolve oil, easy to foam.Rosin is sticky and prevents soap from cracking and rancidity.
In the building materials industry:
Rosin is mainly used as concrete foaming agent and floor tile bonding agent in building material industry.Rosin is also used as a binder for viny l chlorid e asbestos tiles.Rosin and linseed oil, calcium carbonate, charcoal, pigment, etc. can be mixed together to manufacture carpet tiles.
In the flux:
Because the metal surface and air contact will generate a layer of oxide film, the higher the temperature, the thicker the oxide layer.This oxide film prevents liquid solder from wetting the metal, just as oil prevents water from wetting glass.Flux is a special material for removing oxide film, also known as flux.Flux has three main functions:
1. Removal of oxide film: in essence, the material in the flux reduction reaction, so as to remove the oxide film, reaction
products into suspended slag, floating on the surface of the solder.
2. Prevent oxidation: after melting, floating on the surface of the solder, forming an isolation layer, thus preventing the
oxidation of the welding surface.
3. Reduce the surface tension: increase the fluidity of the solder and help the solder to wet the weldment.
