上海電(dian)纜(lan)(lan)(lan)(lan)橋(qiao)架(jia)(jia)附件銷售(shou)?? 電(dian)纜(lan)(lan)(lan)(lan)橋(qiao)架(jia)(jia)附件:? 1. 強(qiang)(qiang)(qiang)(qiang)(qiang)度(du)(du)高(gao),可(ke)設計(ji)性(xing)(xing)(xing)(xing)(xing)好 ??? 連(lian)續纖(xian)(xian)維(wei)(wei)(wei)(wei)增(zeng)(zeng)強(qiang)(qiang)(qiang)(qiang)(qiang)熱(re)(re)固(gu)性(xing)(xing)(xing)(xing)(xing)復合(he)材(cai)(cai)料主(zhu)要由起(qi)增(zeng)(zeng)強(qiang)(qiang)(qiang)(qiang)(qiang)作(zuo)(zuo)(zuo)用(yong)的(de)(de)(de)(de)玻(bo)璃(li)纖(xian)(xian)維(wei)(wei)(wei)(wei)和起(qi)粘(zhan)結作(zuo)(zuo)(zuo)用(yong),傳遞載荷作(zuo)(zuo)(zuo)用(yong)的(de)(de)(de)(de)熱(re)(re)固(gu)性(xing)(xing)(xing)(xing)(xing)樹脂組成(cheng)。玻(bo)璃(li)纖(xian)(xian)維(wei)(wei)(wei)(wei)的(de)(de)(de)(de)拉(la)伸(shen)強(qiang)(qiang)(qiang)(qiang)(qiang)度(du)(du)很(hen)高(gao)(3450mpa),其含(han)量(liang),長度(du)(du),鋪設形(xing)(xing)式(shi)決定支(zhi)架(jia)(jia)制(zhi)品(pin)的(de)(de)(de)(de)強(qiang)(qiang)(qiang)(qiang)(qiang)度(du)(du)。 熱(re)(re)固(gu)性(xing)(xing)(xing)(xing)(xing)的(de)(de)(de)(de)玻(bo)璃(li)纖(xian)(xian)維(wei)(wei)(wei)(wei)增(zeng)(zeng)強(qiang)(qiang)(qiang)(qiang)(qiang)復合(he)材(cai)(cai)料強(qiang)(qiang)(qiang)(qiang)(qiang)度(du)(du)可(ke)以在(zai)30-1000mpa范圍。因此,我們根據產(chan)(chan)品(pin)的(de)(de)(de)(de)受(shou)力情況(kuang),產(chan)(chan)量(liang),生(sheng)產(chan)(chan)工藝,價格(ge)承(cheng)受(shou)能(neng)力來設計(ji)玻(bo)璃(li)纖(xian)(xian)維(wei)(wei)(wei)(wei)的(de)(de)(de)(de)用(yong)量(liang),長度(du)(du)和鋪設形(xing)(xing)式(shi)。 ??? 2.不蠕變 ??? 連(lian)續纖(xian)(xian)維(wei)(wei)(wei)(wei)增(zeng)(zeng)強(qiang)(qiang)(qiang)(qiang)(qiang)熱(re)(re)固(gu)性(xing)(xing)(xing)(xing)(xing)復合(he)材(cai)(cai)料支(zhi)架(jia)(jia)的(de)(de)(de)(de)剛性(xing)(xing)(xing)(xing)(xing)比美國某(mou)公司生(sheng)產(chan)(chan)的(de)(de)(de)(de)纖(xian)(xian)維(wei)(wei)(wei)(wei)增(zeng)(zeng)強(qiang)(qiang)(qiang)(qiang)(qiang)增(zeng)(zeng)強(qiang)(qiang)(qiang)(qiang)(qiang)尼龍支(zhi)架(jia)(jia)增(zeng)(zeng)加一倍。即使在(zai)長期(qi)負載下(xia)(xia)也(ye)不變形(xing)(xing),也(ye)不會出現像(xiang)國內某(mou)些城市地鐵使用(yong)的(de)(de)(de)(de)金屬制(zhi)電(dian)纜(lan)(lan)(lan)(lan)支(zhi)架(jia)(jia)那(nei)樣往下(xia)(xia)傾斜。 ??? 3.防火(huo)(huo) ??? 氧(yang)(yang)指(zhi)數(shu)是(shi)評價電(dian)纜(lan)(lan)(lan)(lan)放火(huo)(huo)產(chan)(chan)品(pin)重要的(de)(de)(de)(de)檢測手(shou)段。 氧(yang)(yang)指(zhi)數(shu)是(shi)指(zhi)在(zai)氧(yang)(yang)氣條件下(xia)(xia),防火(huo)(huo)產(chan)(chan)品(pin)耐燒(shao)的(de)(de)(de)(de)特性(xing)(xing)(xing)(xing)(xing)。在(zai)工程中(zhong)使用(yong)應(ying)根據燃燒(shao)強(qiang)(qiang)(qiang)(qiang)(qiang)度(du)(du)確(que)定。例如(ru),在(zai)30根電(dian)纜(lan)(lan)(lan)(lan)的(de)(de)(de)(de)條件下(xia)(xia),如(ru)發生(sheng)電(dian)纜(lan)(lan)(lan)(lan)引燃事故,在(zai)4min以內即可(ke)形(xing)(xing)成(cheng)500度(du)(du)以上高(gao)溫熱(re)(re)聚集,從(cong)而導致電(dian)纜(lan)(lan)(lan)(lan)沿走(zou)向進行延(yan)燃。電(dian)纜(lan)(lan)(lan)(lan)密(mi)集處(chu)的(de)(de)(de)(de)電(dian)纜(lan)(lan)(lan)(lan)越多,可(ke)燃體(ti)質量(liang)越大。在(zai)30根電(dian)纜(lan)(lan)(lan)(lan)時,單位長度(du)(du)可(ke)燃體(ti)質量(liang)為(wei)(wei)20.5kg/m,現在(zai)以300根電(dian)纜(lan)(lan)(lan)(lan)計(ji)算(suan),單位長度(du)(du)可(ke)燃體(ti)質量(liang)為(wei)(wei)158kg/m,按可(ke)能(neng)產(chan)(chan)生(sheng)燃燒(shao)強(qiang)(qiang)(qiang)(qiang)(qiang)度(du)(du)計(ji)算(suan),氧(yang)(yang)指(zhi)數(shu)要不小于65%。我們認為(wei)(wei),產(chan)(chan)品(pin)防火(huo)(huo)標準中(zhong)氧(yang)(yang)指(zhi)數(shu)定在(zai)70%比較。"上海電(dian)纜(lan)(lan)(lan)(lan)橋(qiao)架(jia)(jia)附件銷售(shou)
