Hebei Messi Biology Co., Ltd. specializes in the research and development and production of pharmaceutical and food grade magnesium oxide, high-purity nano-grade magnesium oxide, and ordinary industrial grade magnesium oxide. It is a national high-tech enterprise, a “specialized and new” enterprise in Hebei Province, and a national technology-based enterprise. Combining many years of rich experience in the research and development and production of magnesium oxide, it has a unique understanding of the application of magnesium oxide in different rubber products.
① Active magnesium oxide is mainly used as a reinforcing agent for rubber to give rubber good corrosion resistance, tear resistance, elasticity and elongation.
② Magnesium oxide is used as an accelerator for rubber vulcanization process. It is a multifunctional rubber compounding agent, mainly used as a vulcanization activator and reinforcing agent for natural rubber, synthetic rubber, and latex.
③ When magnesium oxide is used as a vulcanization activator, it is evenly distributed in the rubber material, has a large contact area with hydrogen sulfide, and has a greater opportunity for interfacial reaction. In addition, the active magnesium oxide product has the catalytic effect of active substances, which makes the conversion rate of magnesium oxide high.
④ Magnesium oxide can be used as a vulcanization oxidant to enhance the activity of the accelerator, reduce the amount of accelerator, and shorten the vulcanization cycle.
⑤ Magnesium oxide can accelerate the vulcanization speed, improve the thermal conductivity of the vulcanized rubber, and make the vulcanization more thorough.
⑥ In the rubber industry, especially in the production of transparent rubber products, active magnesium oxide is an excellent vulcanization activator.
The difference in the role of magnesium oxide in different rubber industries:
1. High-grade black and dark rubber tires, radial tires: Magnesium oxide can improve the thermal conductivity, wear resistance, tear resistance, tensile strength and other indicators of the product, and can save about 30% of the amount of magnesium oxide.
2. Synthetic rubber: Magnesium oxide can be used as an activator, vulcanization accelerator and reinforcing agent, and has a coloring effect. It promotes the vulcanization, activation, reinforcement and anti-aging of rubber, can strengthen the vulcanization process, and improve the tear resistance and wear resistance of rubber products.
3. Natural rubber: Magnesium oxide can be used as a vulcanization activator to promote the vulcanization, activation, reinforcement and anti-aging of rubber, strengthen the vulcanization process, and improve the tear resistance and wear resistance of rubber products.
4. Latex: Magnesium oxide can be used as an activator to promote the vulcanization, activation, reinforcement and anti-aging of rubber, strengthen the vulcanization process, and improve the tear resistance and wear resistance of rubber products.
5. White latex: Magnesium oxide can be used as a colorant and filler.
6. Neoprene: Magnesium oxide can be used as a vulcanizing agent and a compounding agent to increase thermal conductivity.
7. The shoemaking industry is used for labor protection products such as rubber shoes, rain boots, and rubber gloves: Magnesium oxide can improve wear resistance and anti-aging, and extend service life.
8. Transparent rubber and rubber products for food: Magnesium oxide is an indispensable inorganic activator for transparent rubber and rubber products for food.
9. Transparent and translucent rubber function: Magnesium oxide can be used as a vulcanization activator.
10. Transparent or colored rubber products: Magnesium oxide is used in transparent or colored rubber products, and plays an irreplaceable role that traditional surfactants such as carbon black cannot.
