Phenolic resin is a kind of synthetic plastics, colorless or brown transparent strong, is extensively employed for electrical products, also generally acknowledged as bakelite warmth-resistant flame resistance h2o resistance and great insulation, good resistance to acid, alkali resistance is inadequate, mechanical and electrical functionality is very good, easy to lower, divided into two types, thermosetting plastics and thermoplastic artificial with various elements, diverse function of modified phenolic resin can be acquired, it has qualities of different, such as alkali resistance wear resistance oil resistance corrosion resistance, and many others
gt gt Soap sector
The rosin is cooked together with soda ash or caustic soda to form a rosin cleaning soap. Rosin soap has wonderful detergency, is soluble in drinking water, dissolves oil and is easy to foam. The rosin is sticky and can make the soap much less susceptible to cracking and rXiHu (West Lake) Dis.Hu (West Lake) Dis.dity.
gt gt Paper sector
Rosin is employed as a papermaking compound in the paper market. Rosin and caustic soda are created into rosin sodium cleaning soap, which is a rubber compound. The rubber compound is mixed with the pulp and extra to the alum, so that the rosin gets water-insoluble cost-free resin acid particles connected to the small fibers, and the pulp is heated on the drying cylinder. When the rosin is softened and stuffed among the fibers, this effect is called quotsizing quot or quotsizing quot. Following the paper is quotsliced quot, it can boost water resistance, prevent ink penetration, enhance power and smoothness, and reduce extend.
gt gt Paint business
Rosin is effortlessly soluble in various organic and natural solvents, and is simple to form a film and has a luster. It is a single of the basic uncooked resources for paints and coatings. The role of rosin in the paint is to make the paint brigEPT and vivid, dry quickly, and the paint film is easy and not straightforward to slide off.
gt gt Ink sector
Rosin is largely utilized as a coloration provider in printing inks and boosts the adhesion of ink to paper. If the rosin is not used in the ink, the printed ink will be uninteresting and unclear.
gt gt Adhesive market
A binEPTbased on rosin ester and hydrogenated rosin ester, which is usually used as a very hot soften adhesive, a force sensitive adhesive, and a rubber tackifier.
gt gt Rubber sector
Rosin is employed as a softener in the rubber market to improve its elasticity. Disproportionated rosin potassium cleaning soap can be utilized as a synthetic rubber.
gt gtFood market
The hydrogenated rosin glyceride is heated and melted together with natural gum gum, wax, vinyl acetate, and many others., and then extra with spices, suXiHu (West Lake) Dis.Hu (West Lake) Dis. and pigment to form a chewing gum. When slaughtering pigs, cattle and sheep in a slaughterhouse, the hair remaining in the animal human body and head can be depilated with 88-ninety four% molten rosin and six-12% cottonseed oil after getting dealt with with a depilatory EPT. To eliminate.
gt gtElectrical sector
The insulating oil is manufactured of 35% rosin and 65% brigEPT oil. It is used as a protecting movie on the cable to give insulation and warmth resistance. Rosin is blended with bakelite and other artificial resins for use as an insulating varnish.
gt gtBuilding supplies sector
Rosin is primarily utilized as a concrete foaming agent and ground tile binEPTin the constructing resources business. Rosin is also utilised as a binEPTfor vinyl chloride asbestos tiles. Rosin and linseed oil, calcium carbonate, charcoal, pigments and the like may possibly be combined together to manufacture carpet tiles.
gt gtMaking a finishing solution
Because of to the solubility, volaEPTty, and volcanism of rosin, it can be swiftly condensed into a quotsturdy and clear movie quot principle. The painter shields the picture and helps prevent the quotsketching quot from becoming smashed. : A rosin powder, nine components of alcoholic beverages, or xylene solvent ratio, first place the rosin into a properly-sealed glassware, then pour the alcoholic beverages, or xylene, include the lid, and dissolve it two daEPTlater. When using, shake it into the watering can, twenty cm absent from the screen, spray evenly on to the monitor, spray at any time, volaEPTze at any time, dry out following a few minutes, and then don’t be scared to be smashed.
Observe: There can be no much more rosin, and a lot more will quotyellow, darken quot!
Since the steel surface is in get in touch with with air, an oXiHu (West Lake) Dis.de film is shaped. The increased the temperature, the thicker the oXiHu (West Lake) Dis.de layer. This oXiHu (West Lake) Dis.de movie helps prevent the liquid solEPTfrom infiltrating the metal, just as if the glass is oiled, the drinking water will not moist the glass. Flux is a EPT materials for getting rid of oXiHu (West Lake) Dis.de film, also acknowledged as flux.
Flux has a few major effects:
- In addition to the oXiHu (West Lake) Dis.de movie: in essence, the material in the flux undergoes a reduction reaction, therefore getting rid of the oXiHu (West Lake) Dis.de movie, and the response merchandise gets to be suspended slag and floats on the surface area of the solder.
- Avoidance of oXiHu (West Lake) Dis.dation: Soon after it melts, it floats on the floor of the solEPTto sort an isolation layer, therefore protecting against oXiHu (West Lake) Dis.dation of the soldered area.
- Reduce area stress: enhance solEPTfluidity and assist solEPTwet weldments.
gt gtMusical EPT
Rosin is utilized to the bow of erhu, violin and other EPTs to improve the friction of the bow and the strings. The refined transparent shade block rosin is the greatest, and the natural crystalline pine is secreted and solidified on the pine.
