Sic ramming mass production ratio

1. 炭化ケイ素粉末 is the main component that provides hardness and durability to the ramming material.
2. Binder: Commonly used binders include resins, ceramic binders, 等, which are used to bond silicon carbide powder together and keep it in a certain solid form.
3. Lubricant: Lubricants such as polyvinyl alcohol and beeswax are usually used to reduce the friction between silicon carbide powders and improve the fluidity of the ramming material.
4. Mold release agent: used to apply to the ramming material mold to facilitate the smooth removal of the ramming material from the mold.
5. Other additives: According to needs, some other additives, such as pigments, fillers, 等, can be added to improve the performance of the ramming material or meet specific needs
