玻璃鋼/不銹鋼膜殼概述

玻(bo)璃(li)鋼(gang)（FRP）亦稱(cheng)作(zuo)(zuo)GFRP，即纖(xian)(xian)(xian)維(wei)強(qiang)化塑料，一(yi)般指用(yong)玻(bo)璃(li)纖(xian)(xian)(xian)維(wei)增(zeng)強(qiang)不(bu)飽(bao)和聚(ju)酯、環氧樹脂(zhi)與酚醛樹脂(zhi)基體。以玻(bo)璃(li)纖(xian)(xian)(xian)維(wei)或其(qi)制品作(zuo)(zuo)增(zeng)強(qiang)材(cai)料的增(zeng)強(qiang)塑料，稱(cheng)謂為(wei)玻(bo)璃(li)纖(xian)(xian)(xian)維(wei)增(zeng)強(qiang)塑料，或稱(cheng)為(wei)玻(bo)璃(li)鋼(gang)，不(bu)同于(yu)鋼(gang)化玻(bo)璃(li)。

由(you)于所使(shi)用(yong)的樹脂品種(zhong)不同，因此(ci)有聚酯玻(bo)璃(li)鋼(gang)、環氧玻(bo)璃(li)鋼(gang)、酚醛(quan)玻(bo)璃(li)鋼(gang)之(zhi)別。質(zhi)輕而硬，不導電，性能穩(wen)定，機(ji)械強度高，回收利用(yong)少，耐腐蝕(shi)。可以代(dai)替鋼(gang)材制(zhi)造機(ji)器零件(jian)和(he)汽車、船舶(bo)外(wai)殼等。

玻(bo)(bo)璃鋼(gang)學(xue)名纖(xian)(xian)(xian)(xian)(xian)維(wei)增(zeng)(zeng)強(qiang)塑(su)(su)料(liao)(liao)(liao)(liao)(liao)，俗稱FRP（Fiber Reinforced Plastics），即纖(xian)(xian)(xian)(xian)(xian)維(wei)增(zeng)(zeng)強(qiang)復合(he)(he)塑(su)(su)料(liao)(liao)(liao)(liao)(liao)。根據采用的(de)纖(xian)(xian)(xian)(xian)(xian)維(wei)不同分(fen)為(wei)玻(bo)(bo)璃纖(xian)(xian)(xian)(xian)(xian)維(wei)增(zeng)(zeng)強(qiang)復合(he)(he)塑(su)(su)料(liao)(liao)(liao)(liao)(liao)（GFRP），碳(tan)纖(xian)(xian)(xian)(xian)(xian)維(wei)增(zeng)(zeng)強(qiang)復合(he)(he)塑(su)(su)料(liao)(liao)(liao)(liao)(liao)（CFRP），硼纖(xian)(xian)(xian)(xian)(xian)維(wei)增(zeng)(zeng)強(qiang)復合(he)(he)塑(su)(su)料(liao)(liao)(liao)(liao)(liao)等。它是以(yi)玻(bo)(bo)璃纖(xian)(xian)(xian)(xian)(xian)維(wei)及其制品(pin)（玻(bo)(bo)璃布(bu)、帶、氈、紗等）作為(wei)增(zeng)(zeng)強(qiang)材(cai)(cai)(cai)料(liao)(liao)(liao)(liao)(liao)，以(yi)合(he)(he)成樹脂作基(ji)(ji)體(ti)材(cai)(cai)(cai)料(liao)(liao)(liao)(liao)(liao)的(de)一種(zhong)復合(he)(he)材(cai)(cai)(cai)料(liao)(liao)(liao)(liao)(liao)。纖(xian)(xian)(xian)(xian)(xian)維(wei)增(zeng)(zeng)強(qiang)復合(he)(he)材(cai)(cai)(cai)料(liao)(liao)(liao)(liao)(liao)是由增(zeng)(zeng)強(qiang)纖(xian)(xian)(xian)(xian)(xian)維(wei)和基(ji)(ji)體(ti)組成。纖(xian)(xian)(xian)(xian)(xian)維(wei)（或(huo)晶須）的(de)直徑很小(xiao)，一般在10μm以(yi)下，缺陷(xian)較少又(you)較小(xiao)，斷裂應變(bian)(bian)約為(wei)千分(fen)之三十以(yi)內，是脆性(xing)材(cai)(cai)(cai)料(liao)(liao)(liao)(liao)(liao)，易損傷、斷裂和受(shou)到腐蝕(shi)。基(ji)(ji)體(ti)相對(dui)于纖(xian)(xian)(xian)(xian)(xian)維(wei)來說，強(qiang)度、模量都要低很多(duo)，但可以(yi)經受(shou)住(zhu)大的(de)應變(bian)(bian)，往(wang)往(wang)具有(you)粘彈性(xing)和彈塑(su)(su)性(xing)，是韌性(xing)材(cai)(cai)(cai)料(liao)(liao)(liao)(liao)(liao)。

不銹鋼膜殼是反(fan)滲(shen)透(tou)設備的基本組(zu)成部(bu)分，材質(zhi)采用(yong)304不銹鋼無縫(feng)管，按端蓋密(mi)封(feng)形式分為(wei)：卡(ka)箍式、法蘭式、內置式；按進(jin)水方式分為(wei)：端進(jin)、側進(jin)。長度與(yu)反(fan)滲(shen)透(tou)膜組(zu)件數(shu)量配套；產品內外拋光，美(mei)觀(guan)實用(yong)，使(shi)用(yong)壓力(li)達到反(fan)滲(shen)透(tou)系統正常運轉壓力(li)要求。
