Product details電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)橋架(jia)(jia)(jia)(jia)(jia)附件(jian)批發(fa)(fa)?? 電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)橋架(jia)(jia)(jia)(jia)(jia)附件(jian):? 1. 強(qiang)(qiang)(qiang)度高,可(ke)(ke)設計性好 ??? 連續纖(xian)維增(zeng)(zeng)(zeng)強(qiang)(qiang)(qiang)熱(re)(re)固性復(fu)合(he)(he)材料主要由起(qi)增(zeng)(zeng)(zeng)強(qiang)(qiang)(qiang)作用(yong)(yong)的(de)(de)玻(bo)璃纖(xian)維和(he)起(qi)粘結作用(yong)(yong),傳遞載荷作用(yong)(yong)的(de)(de)熱(re)(re)固性樹脂組成(cheng)。玻(bo)璃纖(xian)維的(de)(de)拉伸強(qiang)(qiang)(qiang)度很(hen)高(3450mpa),其含量(liang)(liang),長(chang)(chang)度,鋪設形式決定支(zhi)架(jia)(jia)(jia)(jia)(jia)制(zhi)品(pin)(pin)的(de)(de)強(qiang)(qiang)(qiang)度。 熱(re)(re)固性的(de)(de)玻(bo)璃纖(xian)維增(zeng)(zeng)(zeng)強(qiang)(qiang)(qiang)復(fu)合(he)(he)材料強(qiang)(qiang)(qiang)度可(ke)(ke)以(yi)在(zai)(zai)(zai)30-1000mpa范圍。因此,我們根據產(chan)品(pin)(pin)的(de)(de)受力(li)情況,產(chan)量(liang)(liang),生產(chan)工藝,價格承受能(neng)力(li)來設計玻(bo)璃纖(xian)維的(de)(de)用(yong)(yong)量(liang)(liang),長(chang)(chang)度和(he)鋪設形式。 ??? 2.不蠕變 ??? 連續纖(xian)維增(zeng)(zeng)(zeng)強(qiang)(qiang)(qiang)熱(re)(re)固性復(fu)合(he)(he)材料支(zhi)架(jia)(jia)(jia)(jia)(jia)的(de)(de)剛性比美國某公(gong)司生產(chan)的(de)(de)纖(xian)維增(zeng)(zeng)(zeng)強(qiang)(qiang)(qiang)增(zeng)(zeng)(zeng)強(qiang)(qiang)(qiang)尼(ni)龍支(zhi)架(jia)(jia)(jia)(jia)(jia)增(zeng)(zeng)(zeng)加一倍(bei)。即使在(zai)(zai)(zai)長(chang)(chang)期負載下(xia)(xia)也不變形,也不會出(chu)現(xian)像國內(nei)某些城市地鐵(tie)使用(yong)(yong)的(de)(de)金屬(shu)制(zhi)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)支(zhi)架(jia)(jia)(jia)(jia)(jia)那樣往下(xia)(xia)傾斜(xie)。 ??? 3.防(fang)火(huo) ??? 氧(yang)(yang)指數(shu)是評價電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)放火(huo)產(chan)品(pin)(pin)重要的(de)(de)檢測手(shou)段。 氧(yang)(yang)指數(shu)是指在(zai)(zai)(zai)氧(yang)(yang)氣(qi)條件(jian)下(xia)(xia),防(fang)火(huo)產(chan)品(pin)(pin)耐燒的(de)(de)特性。在(zai)(zai)(zai)工程中使用(yong)(yong)應根據燃(ran)(ran)燒強(qiang)(qiang)(qiang)度確定。例如(ru),在(zai)(zai)(zai)30根電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)的(de)(de)條件(jian)下(xia)(xia),如(ru)發(fa)(fa)生電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)引燃(ran)(ran)事(shi)故,在(zai)(zai)(zai)4min以(yi)內(nei)即可(ke)(ke)形成(cheng)500度以(yi)上高溫(wen)熱(re)(re)聚(ju)集(ji),從而導致電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)沿走(zou)向進行(xing)延(yan)燃(ran)(ran)。電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)密集(ji)處的(de)(de)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)越多,可(ke)(ke)燃(ran)(ran)體質(zhi)量(liang)(liang)越大。在(zai)(zai)(zai)30根電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)時,單位長(chang)(chang)度可(ke)(ke)燃(ran)(ran)體質(zhi)量(liang)(liang)為(wei)20.5kg/m,現(xian)在(zai)(zai)(zai)以(yi)300根電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)計算,單位長(chang)(chang)度可(ke)(ke)燃(ran)(ran)體質(zhi)量(liang)(liang)為(wei)158kg/m,按可(ke)(ke)能(neng)產(chan)生燃(ran)(ran)燒強(qiang)(qiang)(qiang)度計算,氧(yang)(yang)指數(shu)要不小于65%。我們認為(wei),產(chan)品(pin)(pin)防(fang)火(huo)標(biao)準中氧(yang)(yang)指數(shu)定在(zai)(zai)(zai)70%比較。"電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)橋架(jia)(jia)(jia)(jia)(jia)附件(jian)批發(fa)(fa)
