                产品介绍            
                                                                                                                                                    
                                                                    详细说明                                                                                                     绢云母产品                                                                                                     绢云母(Sericite)是一种天然粒径比较细的白云母,属白云母的亚种,与白云母相比,具有天然粒径细小,易加工的特点。绢云母晶体化学式为:K0.5-1(Al,Fe,Mg)2(SiAl)4O10(OH)2.nH2O结构由两层硅氧四面体夹着一层铝氧八面体构成的复式硅氧层,可劈成极薄的片状,径厚比大,富弹性、可弯曲,耐磨性好,耐酸,耐碱,耐高温(600°C以上)。
                                                                                                    绢云母在涂料中的功能
一、 独特的紫外线屏蔽功能----提高涂膜的耐候性、延迟粉化,增强涂膜的保色性。                                                                                                    二、 高径厚比的片状叠加阻隔功能----提高涂膜的综合机械性能和抗渗透性绢云母在涂料中的功能验证绢云母作为白云母的亚种,具有独特的光学性质、理化性质和应用功能,这些性能在以下涂料领域中得到广泛运用:建筑外墙涂料、防腐蚀涂料、粉末涂料、耐热涂料、绝缘涂料、路标涂料、防水涂料等特种功能性涂料。
