玻璃鋼/不銹鋼膜殼概述

玻(bo)璃(li)(li)鋼（FRP）亦(yi)稱(cheng)作(zuo)GFRP，即纖維強(qiang)(qiang)化(hua)塑料，一般指用玻(bo)璃(li)(li)纖維增(zeng)強(qiang)(qiang)不飽(bao)和聚酯、環氧樹脂與酚醛樹脂基體。以玻(bo)璃(li)(li)纖維或其(qi)制品作(zuo)增(zeng)強(qiang)(qiang)材料的增(zeng)強(qiang)(qiang)塑料，稱(cheng)謂為玻(bo)璃(li)(li)纖維增(zeng)強(qiang)(qiang)塑料，或稱(cheng)為玻(bo)璃(li)(li)鋼，不同于鋼化(hua)玻(bo)璃(li)(li)。

由于所使(shi)用(yong)的樹脂(zhi)品種不(bu)同，因此有聚酯(zhi)玻璃鋼、環氧玻璃鋼、酚醛玻璃鋼之別。質輕而硬，不(bu)導電，性(xing)能穩定，機(ji)械強(qiang)度(du)高，回收利(li)用(yong)少，耐腐蝕。可以(yi)代替鋼材制造機(ji)器(qi)零件和(he)汽車、船舶外(wai)殼等。

玻(bo)璃(li)鋼學(xue)名(ming)纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)增(zeng)(zeng)(zeng)強(qiang)塑料(liao)(liao)(liao)(liao)，俗稱FRP（Fiber Reinforced Plastics），即纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)增(zeng)(zeng)(zeng)強(qiang)復(fu)合(he)(he)塑料(liao)(liao)(liao)(liao)。根(gen)據采用的纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)不同分為(wei)玻(bo)璃(li)纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)增(zeng)(zeng)(zeng)強(qiang)復(fu)合(he)(he)塑料(liao)(liao)(liao)(liao)（GFRP），碳纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)增(zeng)(zeng)(zeng)強(qiang)復(fu)合(he)(he)塑料(liao)(liao)(liao)(liao)（CFRP），硼纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)增(zeng)(zeng)(zeng)強(qiang)復(fu)合(he)(he)塑料(liao)(liao)(liao)(liao)等。它是以(yi)(yi)玻(bo)璃(li)纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)及其制品（玻(bo)璃(li)布、帶、氈、紗等）作為(wei)增(zeng)(zeng)(zeng)強(qiang)材料(liao)(liao)(liao)(liao)，以(yi)(yi)合(he)(he)成(cheng)樹脂(zhi)作基(ji)體(ti)材料(liao)(liao)(liao)(liao)的一(yi)種復(fu)合(he)(he)材料(liao)(liao)(liao)(liao)。纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)增(zeng)(zeng)(zeng)強(qiang)復(fu)合(he)(he)材料(liao)(liao)(liao)(liao)是由(you)增(zeng)(zeng)(zeng)強(qiang)纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)和基(ji)體(ti)組成(cheng)。纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)（或晶須）的直徑很小，一(yi)般(ban)在10μm以(yi)(yi)下，缺(que)陷較少又較小，斷(duan)裂應變(bian)約(yue)為(wei)千分之三(san)十以(yi)(yi)內，是脆性(xing)(xing)材料(liao)(liao)(liao)(liao)，易損傷、斷(duan)裂和受(shou)到腐蝕。基(ji)體(ti)相對于纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)來說，強(qiang)度、模量(liang)都要低(di)很多(duo)，但(dan)可(ke)以(yi)(yi)經(jing)受(shou)住(zhu)大(da)的應變(bian)，往往具有(you)粘彈性(xing)(xing)和彈塑性(xing)(xing)，是韌性(xing)(xing)材料(liao)(liao)(liao)(liao)。

不(bu)銹(xiu)鋼膜殼是反滲(shen)透(tou)(tou)設備的(de)基本組成部分(fen)，材質采用(yong)304不(bu)銹(xiu)鋼無縫管，按端蓋(gai)密(mi)封形式分(fen)為：卡(ka)箍(gu)式、法蘭式、內(nei)置式；按進水方式分(fen)為：端進、側進。長度與反滲(shen)透(tou)(tou)膜組件數量配套；產品(pin)內(nei)外拋光(guang)，美觀實用(yong)，使(shi)用(yong)壓力(li)達(da)到反滲(shen)透(tou)(tou)系(xi)統正常運轉(zhuan)壓力(li)要求(qiu)。
