具有低煙(yan)無(wu)鹵(lu)(lu)LSHF(Low Smoke Halogen Free)特(te)性(xing)(xing)(xing)的(de)(de)(de)電(dian)(dian)纜于(yu)20世紀(ji)70年代推(tui)出,***初用(yong)于(yu)安裝在(zai)小(xiao)型密閉空間中(zhong),如地鐵、隧道、礦井、船舶和(he)(he)潛艇等場(chang)合。隨著(zhu)傳(chuan)統(tong)電(dian)(dian)纜在(zai)火(huo)災中(zhong)產生(sheng)煙(yan)霧的(de)(de)(de)毒性(xing)(xing)(xing)和(he)(he)腐蝕(shi)性(xing)(xing)(xing)的(de)(de)(de)風險(xian)越來越突出,低煙(yan)無(wu)鹵(lu)(lu)特(te)性(xing)(xing)(xing)電(dian)(dian)纜的(de)(de)(de)使用(yong)范圍擴展到越來越多的(de)(de)(de)場(chang)所,比如對關鍵設(she)備和(he)(he)系(xi)統(tong)連續運行要求較高(gao)的(de)(de)(de)數據中(zhong)心、緊(jin)急呼叫中(zhong)心和(he)(he)電(dian)(dian)信交換站;以(yi)及學校、醫院(yuan)(yuan)和(he)(he)養老院(yuan)(yuan)等無(wu)法有效(xiao)迅速撤離人員的(de)(de)(de)特(te)殊場(chang)所。雖然含(han)有鹵(lu)(lu)化成分的(de)(de)(de)電(dian)(dian)纜絕(jue)緣和(he)(he)護套(tao)具有的(de)(de)(de)阻燃性(xing)(xing)(xing),但在(zai)遇火(huo)后(hou)會(hui)(hui)釋放具有毒性(xing)(xing)(xing)和(he)(he)腐蝕(shi)性(xing)(xing)(xing)的(de)(de)(de)煙(yan)氣(qi)。遇火(huo)后(hou)釋放的(de)(de)(de)鹵(lu)(lu)素和(he)(he)普遍(bian)存在(zai)的(de)(de)(de)氫氣(qi)反(fan)應,形成鹵(lu)(lu)化氫,遇水后(hou)形成鹽(yan)酸、或。這些酸可(ke)能(neng)會(hui)(hui)腐蝕(shi)重要結構、部件(jian)和(he)(he)設(she)備,并增加毒性(xing)(xing)(xing)。含(han)鹵(lu)(lu)的(de)(de)(de)電(dian)(dian)纜在(zai)燃燒時還(huan)會(hui)(hui)顯(xian)著(zhu)提高(gao)一(yi)氧化碳含(han)量,其潛在(zai)危險(xian)更高(gao)。
實踐證明(ming),在(zai)這些商(shang)業(ye)和住宅建(jian)(jian)筑中(zhong)使用低煙(yan)無鹵電(dian)(dian)纜有(you)(you)助于(yu)減(jian)少設備損(sun)壞,降低毒性煙(yan)氣的(de)釋放(fang),同時成為(wei)涉及(ji)環境和可(ke)持(chi)續因素的(de)綠色(se)環保(bao)新建(jian)(jian)項目的(de)合理(li)選擇。在(zai)美國(guo)使用低煙(yan)無鹵電(dian)(dian)纜可(ke)能(neng)(neng)會(hui)滿足美國(guo)綠色(se)建(jian)(jian)筑委員會(hui)LEED(Leadership in Energy and Environmental Design)綠色(se)建(jian)(jian)筑倡議的(de)項目信貸條件(jian)。目前電(dian)(dian)纜產品除使用金(jin)屬導(dao)體外,重要組(zu)成是(shi)聚(ju)合物(wu)(wu)材料(liao)。幾十年(nian)來,電(dian)(dian)纜的(de)絕緣(yuan)和護套(tao)材料(liao)中(zhong)通常會(hui)添加溴化(hua)(hua)(hua)物(wu)(wu)等鹵化(hua)(hua)(hua)成分(fen)來改善阻燃特性。絕緣(yuan)和護套(tao)所使用的(de)聚(ju)氯乙烯(xi)(PVC),氟化(hua)(hua)(hua)乙烯(xi)丙烯(xi)和氯化(hua)(hua)(hua)聚(ju)乙烯(xi)都含有(you)(you)鹵素。其他用于(yu)電(dian)(dian)纜中(zhong)的(de)化(hua)(hua)(hua)合物(wu)(wu)也(ye)有(you)(you)可(ke)能(neng)(neng)含有(you)(you)其他鹵化(hua)(hua)(hua)成分(fen)的(de)樹脂、添加劑和色(se)母(mu)。

不(bu)(bu)同(tong)用途對阻燃性(xing)有(you)不(bu)(bu)同(tong)要求(qiu),一般說來,人們(men)總希望材(cai)料(liao)(liao)的(de)(de)(de)(de)阻燃性(xing)級(ji)(ji)(ji)別(bie)(bie)高(gao)一些。但事實上各種(zhong)阻燃測(ce)試方法(fa)都(dou)有(you)其(qi)局(ju)限性(xing),其(qi)結論都(dou)是相對的(de)(de)(de)(de)。因(yin)(yin)此并不(bu)(bu)是阻燃級(ji)(ji)(ji)別(bie)(bie)越高(gao)越好,例如通常(chang)認(ren)為UL94 V-0級(ji)(ji)(ji)的(de)(de)(de)(de)材(cai)料(liao)(liao)比(bi)(bi)V-2級(ji)(ji)(ji)的(de)(de)(de)(de)好。然而某些電(dian)器產品要求(qiu)材(cai)料(liao)(liao)具(ju)有(you)抗電(dian)弧點燃性(xing),這(zhe)時V-2級(ji)(ji)(ji)就比(bi)(bi)V-0級(ji)(ji)(ji)好。因(yin)(yin)為94V-2級(ji)(ji)(ji)塑料(liao)(liao)不(bu)(bu)會在電(dian)作(zuo)用下形成導(dao)電(dian)而結焦,從而大(da)(da)大(da)(da)降低了著火的(de)(de)(de)(de)可(ke)能性(xing),而94 V-0級(ji)(ji)(ji)塑料(liao)(liao)則相反。首先(xian),目前投入市場的(de)(de)(de)(de)各種(zhong)通信線纜(lan),具(ju)有(you)很多(duo)種(zhong)不(bu)(bu)同(tong)的(de)(de)(de)(de)標準和要求(qiu),每一種(zhong)都(dou)具(ju)有(you)不(bu)(bu)同(tong)的(de)(de)(de)(de)耐火、防(fang)煙(yan)、抗腐蝕和放(fang)毒性(xing)等特(te)性(xing)。這(zhe)些特(te)性(xing)取決于(yu)線纜(lan)的(de)(de)(de)(de)材(cai)料(liao)(liao)成分、外皮尺(chi)寸及(ji)內部導(dao)線絕緣等。
數據通信線(xian)(xian)纜的(de)(de)(de)防(fang)火(huo)(huo)性(xing)(xing)能(neng)(neng)主要取決于其外(wai)皮的(de)(de)(de)材(cai)料(liao),目(mu)前總體(ti)上主要分為以下三種(zhong):普(pu)(pu)通(PVC)型:目(mu)前國內(nei)大多(duo)數局域網布線(xian)(xian)使用(yong)的(de)(de)(de)線(xian)(xian)纜外(wai)套使用(yong)的(de)(de)(de)都是PVC(聚氯乙烯)材(cai)料(liao),PVC是在聚乙烯(PE)里面加入氯元素,用(yong)以提高線(xian)(xian)纜的(de)(de)(de)燃(ran)點,PVC線(xian)(xian)纜的(de)(de)(de)優點是價格較低,機械性(xing)(xing)能(neng)(neng)穩定,缺點是燃(ran)點低,火(huo)(huo)焰(yan)蔓延速度快,燃(ran)燒(shao)時發散出(chu)有(you)(you)毒的(de)(de)(de)煙霧,能(neng)(neng)見度低,燃(ran)燒(shao)時釋放出(chu)熱量較多(duo)。另外(wai)還有(you)(you)一(yi)種(zhong)防(fang)火(huo)(huo)型PVC,同樣可燃(ran)且產生有(you)(you)毒氣體(ti),但燃(ran)點比普(pu)(pu)通PVC材(cai)料(liao)高。
