鋅鋼道路護欄抗沖擊改性劑的特點要求

來源: 時間:2018-08-08 17:06:47 瀏覽次數:

目前鋅鋼道路護欄型材企業使用普遍的抗沖擊改性劑有二類:CPE和ACR.CPE類價格相對便宜,丙烯酸脂ACR抗沖改性劑價格較高,但國產的質量不如進口的穩定,宜選用國外進口產品。國外的產品如:PA4006、KM355P、PM21。鋅鋼護欄面對的填料可以選擇硬脂酸、偶聯劑處理的用量直接影響型材的白度、光澤度、尺寸變化率、硬度等指標。顏料學則應注意耐熱性指標要高,制成木母料以便使之分散均勻。

 鋅鋼道路護欄企業對于潤滑體系的選擇要注意內外潤滑平衡。既不能過量使用潤滑劑,也不能過量使用內滑劑,否則會使產品的性能下降。潤滑體系的選擇要經過實踐驗證后才能用于生產。另外鋅鋼護欄企業認為潤滑體系的選擇還要與穩定劑的使用相適應,一般有機錫配方中外潤滑劑的用量要適當的增加。
