I believe everyone is very familiar with silica, and it is also very common in our daily life, but you still don’t know about some items that contain silica in life. The following Chaoxin will take you with you in time for the white carbon black in life. Apply it.

1. In silicone rubber, white carbon black will react in silicone rubber. For general silicone rubber, ordinary ultra-fine is needed. For high-quality silicone rubber, low iron is required (the iron is high and the product color becomes yellow. , Redness) products. Low-iron products with high oil absorption and large specific surface area are the best choice, which can better react with silicone rubber raw materials.

2. For plastics and plastic products, products with a large specific surface area and high oil absorption are better, and it is better to need to be modified, so that the resulting product is wear-resistant, aging-resistant, and transparent, and maintains the original color of the pigment.

3. Hard rubber pads require silica with low surface area and low oil absorption value.

4. Toothpaste friction agents also require ultra-fine products with low specific surface and low oil absorption values; for toothpaste thickeners, high specific surface and high oil absorption values ​​are required. Some people use the intermediate product of the two as a mixed additive, which is not advisable.

5. For water-absorbent silica, such as diapers, products with high oil absorption values ​​are required, which can better absorb urine and replace water-absorbent resins. When in use, the air in the white carbon black powder should be evacuated to compress the volume.
