在宽域的温度范围内,含白炭黑的胎面胶在湿滑路面上的抓着性及在干燥路面上的转向稳定性,均显著优于含炭黑的胎面胶。含中等及少量白炭黑的胎面胶与干燥路面的摩擦系数得以提高。但在严苛的磨耗条件下,随白炭黑含量增加,磨耗程度提高。在“中等”磨耗条件下,磨耗程度不变。而在“温和”磨耗条件下,磨耗与白炭黑之间存在着复杂的相关性。 In the wide temperature range, the traction of white carbon-containing tread rubber on wet slippery road surface and steering stability on dry pavement are significantly better than the carbon black-containing tread rubber. Friction coefficient of tread rubber with medium and small amount of white carbon and dry road is improved. However, under severe wear conditions, the degree of wear increases with increasing silica content. In the “medium” wear conditions, the same degree of wear. In the “mild” wear conditions, there is a complex correlation between abrasion and silica.
