兴安盟彩色沥青色粉河南彩砖用颜料铁红铁黄铁铁黑铁绿厂家 汇祥颜料彩色沥青色粉颜料厂家 集料需能有好的颗粒样式,针片状颗粒含量低,洁净、干性、无风化、无杂质。 (2)粗集料需能有压碎值、孚美损耗值小;并与脱色沥青黏附性强,一般性需求需≥4级。细集料应得洁净,且砂当量、含泥量应得适合用在技术指标需求。 (3)在选择集料时,相当要重视原岩的选择。由于沥青属于那种偏酸性选材,选择粗集料时应防止采纳酸性石料(如花岗岩、石英岩等),其与沥青的黏附力差、水流利性不良,选择与沥青可以中和,黏附力好、水稳定性强的碱性石料。 (4)在配制颜色联合料的集料时,需要选择色泽与所配制的联合料彩色相似的选材。如果采购颜色碎石料留存困难,则采纳色彩浅淡的碎石及石屑。或选择由人造所烧制出的色彩可选性多,彩色更鲜明明显的颜色彩色陶瓷颗粒。 (5)外掺剂的选择能利用添加剂好比如抗剥落剂来增进彩色沥青地面的抗水损害能力及增加地面利用年限,抗剥落剂的掺人量需使用实验明了(一般性为3‰)。此外,可加入沥青专门用纤维(如聚酯纤维、木质素纤维等),经合成可促成总数庞大的纤维单丝的立体散布,起到加筋和桥接的功用,见效的增进力学性能,阻止开裂。兴安盟彩色沥青 兴安盟彩色沥青厂家 兴安盟彩色沥青价格 Iron Oxide Red Product synopsis: Iron oxide red is dark red powder, Synthetic inorganic pigments Product features: 1.
