  • 云母粉在輪胎中的應用

  • 云母粉在輪胎胎面中的應用 云母粉是用天然云母礦石研磨而成的粉末材料,具有優良的耐熱性、耐酸堿性和耐磨性能,是一種**廉的補強填充劑。云母粉與白炭黑、辦補強炭黑、超補強炭黑以及碳酸鈣等填料在膠料中的物理性能對比,有過很多的報道,云母粉具有比白炭黑高的力學性能,硬度變化率小于白炭黑,且云母粉的拉伸強度保持率和拉伸伸長率保持率遠高于白炭黑。云母粉能提高胎面膠的力學性能和耐熱老化性能,同時耐磨性能和炭黑相當。 云母粉具有一定的補強性能,且回彈性高、對膠料的老化性能、疲勞性能都有提高、且硫化時間縮短、云母粉在常規性能中、拉伸強度、伸長率、撕裂清度均有所提高。 石家莊辰興實業有限公司生產的云母粉,采用優質云母礦石研磨,純度高、雜質含量低。徑厚比大、容重輕、白度好。
