玻璃纤维杆材料分类

玻璃纤维杆材料分类
　　玻璃纤维按形态和长度，可分为连续纤维、定长纤维和玻璃棉；按玻璃成分，可分为无碱、耐化学、高碱、中碱、高强度、高弹性模量和抗碱玻璃纤维等。 　　生产玻璃纤维的主要原料是：石英砂、氧化铝和叶蜡石、石灰石、白云石、硼酸、纯碱、芒硝、萤石  磨碎玻璃纤维
等(deng)(deng)。生(sheng)产方法(fa)(fa)大(da)致(zhi)分两类：一类是将熔(rong)(rong)融玻(bo)璃(li)(li)(li)(li)直(zhi)接制(zhi)(zhi)成纤(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)；一类是将熔(rong)(rong)融玻(bo)璃(li)(li)(li)(li)先制(zhi)(zhi)成直(zhi)径(jing)20mm的(de)(de)(de)(de)(de)玻(bo)璃(li)(li)(li)(li)球或(huo)棒，再以多种(zhong)方式加热重熔(rong)(rong)后(hou)制(zhi)(zhi)成直(zhi)径(jing)为(wei)(wei) 3～80μm的(de)(de)(de)(de)(de)甚(shen)细纤(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)。通(tong)过(guo)铂合金板(ban)以机(ji)械拉丝方法(fa)(fa)拉制(zhi)(zhi)的(de)(de)(de)(de)(de)无限长(zhang)的(de)(de)(de)(de)(de)纤(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)，称为(wei)(wei)连续(xu)玻(bo)璃(li)(li)(li)(li)纤(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)，通(tong)称长(zhang)纤(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)。通(tong)过(guo)辊(gun)筒或(huo)气流(liu)制(zhi)(zhi)成的(de)(de)(de)(de)(de)非(fei)连续(xu)纤(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei),称为(wei)(wei)定长(zhang)玻(bo)璃(li)(li)(li)(li)纤(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei),通(tong)称短纤(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)。借(jie)离心力(li)或(huo)高速气流(liu)制(zhi)(zhi)成的(de)(de)(de)(de)(de)细、短、絮状纤(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)，称为(wei)(wei)玻(bo)璃(li)(li)(li)(li)棉。玻(bo)璃(li)(li)(li)(li)纤(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)经加工，可制(zhi)(zhi)成多种(zhong)形态的(de)(de)(de)(de)(de)制(zhi)(zhi)品，如(ru)纱(sha)、无捻粗纱(sha)、短切(qie)原丝、布、带(dai)、毡、板(ban)、管等(deng)(deng)。 　　玻(bo)璃(li)(li)(li)(li)纤(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)按组成、性质和用(yong)(yong)(yong)途(tu)，分为(wei)(wei)不同的(de)(de)(de)(de)(de)级(ji)别。按标准级(ji)规定(见表)，E级(ji)玻(bo)璃(li)(li)(li)(li)纤(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)使用(yong)(yong)(yong)最普遍，广泛用(yong)(yong)(yong)于(yu)(yu)电(dian)绝缘材(cai)料；S级(ji)为(wei)(wei)特殊纤(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)，虽然产量小，但很重要(yao)，因具有超强(qiang)度，主要(yao)用(yong)(yong)(yong)于(yu)(yu)军事防(fang)御，如(ru)防(fang)弹箱等(deng)(deng)；C级(ji)比(bi)E级(ji)更具耐(nai)化学性，用(yong)(yong)(yong)于(yu)(yu)电(dian)池隔离板(ban)、化学滤毒器；A级(ji)为(wei)(wei)碱性玻(bo)璃(li)(li)(li)(li)纤(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)，用(yong)(yong)(yong)于(yu)(yu)生(sheng)产增强(qiang)材(cai)料。
