玻璃鋼/不銹鋼膜殼概述

玻(bo)璃鋼（FRP）亦稱(cheng)作GFRP，即纖(xian)(xian)維(wei)強(qiang)化(hua)塑料，一般(ban)指用玻(bo)璃纖(xian)(xian)維(wei)增(zeng)強(qiang)不(bu)(bu)飽和聚(ju)酯(zhi)、環氧樹脂(zhi)與酚醛樹脂(zhi)基體。以(yi)玻(bo)璃纖(xian)(xian)維(wei)或其制品作增(zeng)強(qiang)材料的增(zeng)強(qiang)塑料，稱(cheng)謂為玻(bo)璃纖(xian)(xian)維(wei)增(zeng)強(qiang)塑料，或稱(cheng)為玻(bo)璃鋼，不(bu)(bu)同于鋼化(hua)玻(bo)璃。

由于所使用(yong)的(de)樹脂品種不(bu)同，因此(ci)有聚酯玻璃鋼、環(huan)氧玻璃鋼、酚醛玻璃鋼之別。質輕而硬(ying)，不(bu)導電，性能穩定，機械(xie)強(qiang)度高，回收利用(yong)少，耐腐(fu)蝕。可以代替鋼材制造機器零(ling)件和汽車、船(chuan)舶外殼等。

玻(bo)璃(li)(li)鋼學名纖(xian)(xian)(xian)維(wei)(wei)(wei)(wei)增(zeng)(zeng)強(qiang)(qiang)(qiang)塑(su)料(liao)，俗稱FRP（Fiber Reinforced Plastics），即(ji)纖(xian)(xian)(xian)維(wei)(wei)(wei)(wei)增(zeng)(zeng)強(qiang)(qiang)(qiang)復(fu)合塑(su)料(liao)。根據采(cai)用的(de)(de)(de)纖(xian)(xian)(xian)維(wei)(wei)(wei)(wei)不(bu)同分(fen)(fen)為玻(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)(wei)(wei)(wei)增(zeng)(zeng)強(qiang)(qiang)(qiang)復(fu)合塑(su)料(liao)（GFRP），碳(tan)纖(xian)(xian)(xian)維(wei)(wei)(wei)(wei)增(zeng)(zeng)強(qiang)(qiang)(qiang)復(fu)合塑(su)料(liao)（CFRP），硼纖(xian)(xian)(xian)維(wei)(wei)(wei)(wei)增(zeng)(zeng)強(qiang)(qiang)(qiang)復(fu)合塑(su)料(liao)等。它(ta)是(shi)(shi)以玻(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)(wei)(wei)(wei)及其制品（玻(bo)璃(li)(li)布、帶、氈、紗等）作為增(zeng)(zeng)強(qiang)(qiang)(qiang)材(cai)(cai)(cai)料(liao)，以合成樹脂作基(ji)體材(cai)(cai)(cai)料(liao)的(de)(de)(de)一種復(fu)合材(cai)(cai)(cai)料(liao)。纖(xian)(xian)(xian)維(wei)(wei)(wei)(wei)增(zeng)(zeng)強(qiang)(qiang)(qiang)復(fu)合材(cai)(cai)(cai)料(liao)是(shi)(shi)由(you)增(zeng)(zeng)強(qiang)(qiang)(qiang)纖(xian)(xian)(xian)維(wei)(wei)(wei)(wei)和(he)(he)基(ji)體組成。纖(xian)(xian)(xian)維(wei)(wei)(wei)(wei)（或晶須）的(de)(de)(de)直(zhi)徑很小(xiao)，一般在(zai)10μm以下，缺陷較少(shao)又(you)較小(xiao)，斷裂(lie)應(ying)變約為千分(fen)(fen)之三十(shi)以內(nei)，是(shi)(shi)脆性(xing)材(cai)(cai)(cai)料(liao)，易損傷、斷裂(lie)和(he)(he)受到(dao)腐蝕。基(ji)體相對(dui)于纖(xian)(xian)(xian)維(wei)(wei)(wei)(wei)來說，強(qiang)(qiang)(qiang)度(du)、模量(liang)都要低很多，但可以經受住大的(de)(de)(de)應(ying)變，往(wang)往(wang)具(ju)有粘彈(dan)性(xing)和(he)(he)彈(dan)塑(su)性(xing)，是(shi)(shi)韌性(xing)材(cai)(cai)(cai)料(liao)。

不銹鋼膜殼是(shi)反(fan)(fan)滲(shen)透設備(bei)的基本(ben)組成(cheng)部(bu)分，材質采用(yong)304不銹鋼無縫管，按(an)端(duan)蓋密(mi)封形式分為：卡(ka)箍式、法(fa)蘭式、內(nei)置式；按(an)進(jin)水方(fang)式分為：端(duan)進(jin)、側(ce)進(jin)。長度(du)與反(fan)(fan)滲(shen)透膜組件數量(liang)配套；產(chan)品內(nei)外拋光，美觀實(shi)用(yong)，使用(yong)壓力(li)達到反(fan)(fan)滲(shen)透系(xi)統正(zheng)常運轉壓力(li)要求(qiu)。
