What is rubber-grade zinc oxide?
Rubber-grade
zinc oxide is a white hexacrystalline crystal or powder, unsavory, and non-toxic, as well as a penalty in quality. It has a loved one density of 5.606, a refractive index of 2.008-2.009, and also a melting point of 1975. It is soluble in acid, salt hydroxide, as well as ammonium chloride; however insoluble in ammonia, water, as well as ethanol. When revealed to hydrogen sulfide, it does not transfer ultraviolet light as well as does not transform black.
The role of rubber-grade zinc oxide
It is made used in the rubber sector as a vulcanizing representative for all-natural rubber, artificial rubber, and also latex, as an enhancing agent and also colorant, as well as in the manufacturing of radial tires, bias tires, conveyor belts, hoses, tapes, rubber shoes, latex gloves, and also various other rubber products.
Zinc oxide is an important additive for the rubber as well as tire markets as well as is additionally made use of as a vulcanization activator as well as a reinforcing representative for natural rubber, synthetic rubber, and also latex, in addition to a coloring representative. Nano zinc oxide used in rubber can offer full play to the vulcanization-promoting result and improve the efficiency of rubber, and its dose is just 30% to 50% of common zinc oxide
Features of rubber-grade zinc oxide
Solid task, consistent particle dimension, good dispersion, and also good vulcanization promo improve the crosslinking density of vulcanized rubber and also make the vulcanization extra extensive.
It can much better boost the product attachment as well as boost the adhesion of rubber and steel wire as well as cable textile, as well as other skeleton materials.
Excellent vibrant mechanical buildings, small deformation of rubber items, much less warm generation, and also excellent wear resistance, making it have great aging resistance.
The device of activity of rubber-grade zinc oxide.
It is the most essential inorganic energetic agent in the rubber market; adding it to rubber not just can accelerate the vulcanization speed but additionally can enhance the cross-linking degree. It is extensively utilized in all kinds of rubber items, especially for clear rubber items and also products in contact with food. Zinc oxide, as well as stearic acid, are the raw materials for rubber manufacturing and crucial reactants for rubber vulcanization.
In addition to its vulcanizing effect, zinc oxide greatly improves the warmth transfer homes of rubber, thus assisting to dissipate heat from the tire and also make sure driving security. The zinc oxide additive likewise prevents the erosion of rubber by mold and also mold microorganisms or ultraviolet light.
Application of zinc oxide in rubber.
1. Zinc oxide in the rubber tire market (advanced black as well as dark rubber tires, radial tires): enhances the thermal conductivity, abrasion resistance, tear resistance, tensile stamina, and other indicators, as well as can conserve 30% of the amount of zinc oxide.
2. Duty of zinc oxide in rubber products:
① Energetic zinc oxide is generally made used as a reinforcing agent of rubber to make rubber have excellent rust resistance, tear-resistance and also elasticity, and also prolongation.
② It is utilized as an accelerator of the rubber vulcanization process as well as is multi-functional rubber intensifying representative, mostly used as an energetic vulcanization representative as well as reinforcing representative of natural rubber, artificial rubber, as well as latex.
③ As an energetic vulcanization agent, it is evenly dispersed in the rubber product, has a huge call area with hydrogen sulfide, and has a greater chance to execute the interfacial reactions, plus this active zinc oxide item has the assistant catalytic result of energetic compounds to ensure that the conversion rate of zinc oxide into zinc sulfide is high.
④ As a sulfide oxidizer, its function is to enhance the activity of the accelerator, reduce the dosage of the accelerator as well as reduce the vulcanization cycle.
⑤ It can accelerate the vulcanization speed, improve the thermal conductivity of vulcanized rubber, and make the vulcanization much more full.
⑥ In the rubber market, particularly in the manufacturing of clear rubber products, energetic zinc oxide is an excellent vulcanizing energetic agent.
3. Duty of zinc oxide in artificial rubber: as an activator, vulcanization accelerator, and enhancing agent, and also has a tinting impact. Promote the vulcanization of rubber, activation as well as support, anti-aging effect, can strengthen the vulcanization procedure, boost the tear resistance of rubber items, use resistance.
4. Duty of zinc oxide in all-natural rubber and all-natural latex: as an activator, it promotes the vulcanization of rubber, reinforcement, and activation, anti-aging impact, can enhance the vulcanization procedure, boost the tear resistance of rubber products, and put on resistance.
5. Function of zinc oxide in white latex: as a tinting agent and also filler.
6. Role of zinc oxide in neoprene: as a vulcanizing representative and matching representative to enhance thermal conductivity.
7. Role of zinc oxide in the footwear sector (rubber shoes, rainfall boots, rubber handwear covers, and also other labor defense products): boost wear resistance and anti-aging, lengthen life span.
8. Function of zinc oxide in clear rubber and rubber items for food: essential, not natural active agent.
9. The duty of zinc oxide in clear or colored rubber items: it has the irreplaceable duty of conventional energetic agents such as carbon black.
Zinc oxide is the most essential not natural active representative in the rubber industry; including it to rubber not just can increase the vulcanization speed yet likewise can boost the cross-linking level. It is extensively used in all kinds of rubber items, especially for clear rubber items and also products in contact with food. Zinc oxide as well as stearic acid are the raw materials for rubber, making important reactants for rubber vulcanization.
Duty of zinc oxide in synthetic rubber: as activator, vulcanization accelerator, as well as enhancing agent, as well as has coloring effect. Advertise the vulcanization of rubber, reinforcement as well as activation, and anti-aging impact can enhance the vulcanization procedure and improve the tear resistance of rubber products and wear resistance.
