Wet white carbon black masterbatch was successfully used in the production of eight hundred million rubber tyres
Qingdao product quality supervision and inspection institute releases the good news that after testing, eight hundred million rubber company applying wet white carbon black has much better performance in the rolling resistance ,the rolling resistance coefficient reaches 4.841N/kN, comparing with normal tire rolling resistance coefficient of 6.202N/kN ,it decreases by 21.94%.This means the wet white carbon black masterbatch can be used successfully for eight hundred million rubber company tire production.
It is reported that silica is an good filler for green tires. Applying it to tires can reduce heat loss, delay loss and tire rolling resistance, and save fuel. However, white carbon black has larger specific surface area, higher surface free energy, and more unstable surface atoms. It is easy to combine with other atoms. Therefore, when the amount of silica is large, it is difficult to disperse silica into rubber materials by traditional dry mixing process.
Around this problem, the eight hundred million rubber company technology establish a team, and increase R & D investment and cooperate with well-known manufacturers to developed silica wet Millman art.It mainly develop the wet white carbon black from two aspects, the green production process of the wet silica rubber and low rolling resistance .
The application of silica hydrometallurgy process has effectively solved the problem that the traditional white carbon black is difficult to disperse effectively, reduced the rolling resistance of tires, improved the service life of tires, and helped to improve the added value of products and is benefit to develop the European and American markets. Liu Qiang, the chief of the company's formula section, said.
