Carbon black processing factory
In January 2010, Black Cat Company absorbed the most advanced precipitation white carbon black production technology in China. In Jingdezhen, Jiangxi, three 20,000-ton/year precipitation white carbon black production lines were designed and planned to be completed within three years. The first phase of the project will build a production line of 20,000 tons/year, which will be put into operation at the end of October. Welcome customers to inquire.
Second, carbon black processing manufacturers precipitation method white carbon black varieties:
1. Main varieties:
HM-160
HM-170
HM-180
2. The product variety can be determined according to the specific requirements of the user.
Third, packaging materials and specifications:
1. 10Kg/bag, 20Kg/bag, 25Kg/charter bag, can be transported in bulk, can be coded into a bracket and then transported.
2. Packed in tons of bags.
3. The packaging material is made of kraft paper or PP material, and the film is covered with moisture.
4. It can also be packaged according to the packaging form and specifications required by the customer.
HM-160 product introduction
model | HM-160 |
name | Precipitated silica |
Physicochemical properties | HM-160 is a hydrophilic precipitated silica with a specific surface area of 160 m2/g and is a high purity white powder. |
use | Used in tires, carcasses, belts and sidewall rubber as well as rubber products. |
Usage and function | As a reinforcing filler in rubber, it provides high hardness, high tear strength, high tear strength and high wear resistance for rubber formulations, improving the adhesion of rubber and steel cord. Improve the durability of the rubber compound, improve the flexing and impact resistance, improve the traction of the snow tire on the road surface, and improve the all-weather performance of the tire. |
