玻璃纤维杆的组成成分(fen)是(shi)？
玻璃(li)(li)纤(xian)(xian)维按形态(tai)和长度(du)(du)，可分为(wei)连续纤(xian)(xian)维、定长纤(xian)(xian)维和玻璃(li)(li)棉；按玻璃(li)(li)成分，可分为(wei)无碱(jian)(jian)、耐化学、高碱(jian)(jian)、中(zhong)碱(jian)(jian)、高强度(du)(du)、高弹性模量和抗碱(jian)(jian)玻璃(li)(li)纤(xian)(xian)维等。
生(sheng)产玻(bo)(bo)(bo)璃(li)(li)纤(xian)(xian)(xian)(xian)维(wei)的(de)(de)主要原料是(shi)：石(shi)(shi)(shi)英砂、氧化(hua)铝和(he)叶蜡石(shi)(shi)(shi)、石(shi)(shi)(shi)灰石(shi)(shi)(shi)、白云石(shi)(shi)(shi)、硼酸、纯(chun)碱、芒硝(xiao)、萤石(shi)(shi)(shi)等(deng)。生(sheng)产方法(fa)大(da)致分两类：一类是(shi)将(jiang)熔融玻(bo)(bo)(bo)璃(li)(li)直接制(zhi)(zhi)成(cheng)纤(xian)(xian)(xian)(xian)维(wei)；一类是(shi)将(jiang)熔融玻(bo)(bo)(bo)璃(li)(li)先制(zhi)(zhi)成(cheng)直径(jing)20mm的(de)(de)玻(bo)(bo)(bo)璃(li)(li)球(qiu)或(huo)棒，再以(yi)多种方式加热重(zhong)熔后(hou)制(zhi)(zhi)成(cheng)直径(jing)为3～80μm的(de)(de)甚细纤(xian)(xian)(xian)(xian)维(wei)。通(tong)(tong)过铂合(he)金板以(yi)机械拉丝方法(fa)拉制(zhi)(zhi)的(de)(de)无限长(zhang)的(de)(de)纤(xian)(xian)(xian)(xian)维(wei)，称(cheng)(cheng)为连续(xu)玻(bo)(bo)(bo)璃(li)(li)纤(xian)(xian)(xian)(xian)维(wei)，通(tong)(tong)称(cheng)(cheng)长(zhang)纤(xian)(xian)(xian)(xian)维(wei)。通(tong)(tong)过辊筒(tong)或(huo)气流(liu)制(zhi)(zhi)成(cheng)的(de)(de)非连续(xu)纤(xian)(xian)(xian)(xian)维(wei),称(cheng)(cheng)为定长(zhang)玻(bo)(bo)(bo)璃(li)(li)纤(xian)(xian)(xian)(xian)维(wei),通(tong)(tong)称(cheng)(cheng)短纤(xian)(xian)(xian)(xian)维(wei)。借离心力或(huo)高(gao)速气流(liu)制(zhi)(zhi)成(cheng)的(de)(de)细、短、絮状纤(xian)(xian)(xian)(xian)维(wei)，称(cheng)(cheng)为玻(bo)(bo)(bo)璃(li)(li)棉。玻(bo)(bo)(bo)璃(li)(li)纤(xian)(xian)(xian)(xian)维(wei)经加工，可制(zhi)(zhi)成(cheng)多种形(xing)态(tai)的(de)(de)制(zhi)(zhi)品，如纱、无捻粗(cu)纱、短切原丝、布、带、毡、板、管等(deng)。
玻(bo)璃(li)纤维按组成(cheng)、性质和用途，分(fen)为不(bu)同的级(ji)别。按标准级(ji)规定(见表)，E级(ji)玻(bo)璃(li)纤维使用最普遍，广(guang)泛用于(yu)电绝(jue)缘材(cai)料；S级(ji)为特殊纤维，虽然产量小(xiao)，但很重要，因具(ju)有超(chao)强度，主要用于(yu)军事防御(yu)，如(ru)防弹(dan)箱等；C级(ji)比E级(ji)更具(ju)耐化学性，用于(yu)电池隔(ge)离板、化学滤毒器；A级(ji)为碱性玻(bo)璃(li)纤维,用于(yu)生(sheng)产增强材(cai)料。
玻(bo)(bo)璃(li)(li)纤(xian)维(wei)-主要(yao)成分 其(qi)主要(yao)成分为二氧(yang)(yang)(yang)(yang)化(hua)硅、氧(yang)(yang)(yang)(yang)化(hua)铝(lv)、氧(yang)(yang)(yang)(yang)化(hua)钙(gai)(gai)、氧(yang)(yang)(yang)(yang)化(hua)硼、氧(yang)(yang)(yang)(yang)化(hua)镁、氧(yang)(yang)(yang)(yang)化(hua)钠(na)等，根(gen)据玻(bo)(bo)璃(li)(li)中(zhong)(zhong)碱(jian)含(han)量的多少(shao)，可分为无(wu)碱(jian)玻(bo)(bo)璃(li)(li)纤(xian)维(wei)（氧(yang)(yang)(yang)(yang)化(hua)钠(na)0％～2％，属(shu)铝(lv)硼硅酸盐(yan)(yan)玻(bo)(bo)璃(li)(li)）、中(zhong)(zhong)碱(jian)玻(bo)(bo)璃(li)(li)纤(xian)维(wei)（氧(yang)(yang)(yang)(yang)化(hua)钠(na)8％～12％,属(shu)含(han)硼或不含(han)硼的钠(na)钙(gai)(gai)硅酸盐(yan)(yan)玻(bo)(bo)璃(li)(li)）和(he)高(gao)碱(jian)玻(bo)(bo)璃(li)(li)纤(xian)维(wei)（氧(yang)(yang)(yang)(yang)化(hua)钠(na)13％以上(shang)，属(shu)钠(na)钙(gai)(gai)硅酸盐(yan)(yan)玻(bo)(bo)璃(li)(li)）。
