玻璃鋼/不銹鋼膜殼概述

玻(bo)璃(li)(li)鋼（FRP）亦稱作GFRP，即纖(xian)維強(qiang)(qiang)(qiang)化(hua)(hua)塑料，一般(ban)指用(yong)玻(bo)璃(li)(li)纖(xian)維增(zeng)(zeng)強(qiang)(qiang)(qiang)不(bu)飽和聚酯、環(huan)氧樹脂與酚醛樹脂基體(ti)。以(yi)玻(bo)璃(li)(li)纖(xian)維或其制品作增(zeng)(zeng)強(qiang)(qiang)(qiang)材料的(de)增(zeng)(zeng)強(qiang)(qiang)(qiang)塑料，稱謂為(wei)玻(bo)璃(li)(li)纖(xian)維增(zeng)(zeng)強(qiang)(qiang)(qiang)塑料，或稱為(wei)玻(bo)璃(li)(li)鋼，不(bu)同于鋼化(hua)(hua)玻(bo)璃(li)(li)。

由于所使用(yong)的(de)樹脂品種不同(tong)，因此(ci)有聚(ju)酯玻璃(li)鋼(gang)、環氧玻璃(li)鋼(gang)、酚醛(quan)玻璃(li)鋼(gang)之別。質輕而(er)硬，不導電，性能穩(wen)定(ding)，機械強度高(gao)，回收利用(yong)少，耐(nai)腐蝕。可以代替(ti)鋼(gang)材制造機器零件和汽(qi)車、船舶外殼等。

玻璃(li)鋼學名纖(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)增(zeng)強塑(su)(su)(su)(su)料(liao)(liao)，俗稱FRP（Fiber Reinforced Plastics），即纖(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)增(zeng)強復(fu)(fu)合(he)塑(su)(su)(su)(su)料(liao)(liao)。根(gen)據采用的纖(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)不同分為(wei)玻璃(li)纖(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)增(zeng)強復(fu)(fu)合(he)塑(su)(su)(su)(su)料(liao)(liao)（GFRP），碳纖(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)增(zeng)強復(fu)(fu)合(he)塑(su)(su)(su)(su)料(liao)(liao)（CFRP），硼纖(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)增(zeng)強復(fu)(fu)合(he)塑(su)(su)(su)(su)料(liao)(liao)等。它是(shi)以(yi)玻璃(li)纖(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)及其制(zhi)品（玻璃(li)布、帶、氈(zhan)、紗等）作為(wei)增(zeng)強材(cai)(cai)(cai)料(liao)(liao)，以(yi)合(he)成樹脂作基體(ti)(ti)材(cai)(cai)(cai)料(liao)(liao)的一種(zhong)復(fu)(fu)合(he)材(cai)(cai)(cai)料(liao)(liao)。纖(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)增(zeng)強復(fu)(fu)合(he)材(cai)(cai)(cai)料(liao)(liao)是(shi)由增(zeng)強纖(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)和基體(ti)(ti)組成。纖(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)（或晶(jing)須）的直徑(jing)很(hen)小，一般在(zai)10μm以(yi)下(xia)，缺陷較少又較小，斷(duan)裂(lie)應變(bian)約(yue)為(wei)千分之三十以(yi)內(nei)，是(shi)脆性材(cai)(cai)(cai)料(liao)(liao)，易損傷、斷(duan)裂(lie)和受(shou)(shou)到腐蝕。基體(ti)(ti)相(xiang)對于纖(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)來(lai)說，強度、模(mo)量都要低(di)很(hen)多，但可以(yi)經受(shou)(shou)住大(da)的應變(bian)，往往具有粘彈性和彈塑(su)(su)(su)(su)性，是(shi)韌(ren)性材(cai)(cai)(cai)料(liao)(liao)。

不(bu)銹鋼膜(mo)殼是反(fan)滲透(tou)(tou)設備的基本組成部分，材質(zhi)采用(yong)(yong)304不(bu)銹鋼無縫(feng)管，按端(duan)蓋密封形(xing)式(shi)分為(wei)(wei)：卡箍式(shi)、法蘭式(shi)、內(nei)置式(shi)；按進水方(fang)式(shi)分為(wei)(wei)：端(duan)進、側進。長度與反(fan)滲透(tou)(tou)膜(mo)組件(jian)數量配(pei)套(tao)；產品內(nei)外拋(pao)光，美觀實用(yong)(yong)，使(shi)用(yong)(yong)壓(ya)力(li)達到反(fan)滲透(tou)(tou)系統正常(chang)運轉壓(ya)力(li)要求。
