恒溫(wen)電伴(ban)熱(re)(re)帶-旭誠(cheng)(推薦商(shang)家(jia))-天津恒溫(wen)電伴(ban)熱(re)(re)帶

電(dian)伴(ban)熱(re)區別(bie)于傳統的(de)(de)蒸汽(熱(re)水)保(bao)溫方(fang)式(shi)，是一種新型保(bao)溫方(fang)案，在保(bao)溫領域很(hen)有建樹。而電(dian)伴(ban)熱(re)能被(bei)大面積(ji)使用并且逐步取代蒸汽加熱(re)方(fang)式(shi)是有一定的(de)(de)原因，一定的(de)(de)道理的(de)(de)，至于為什么?好在哪?那就(jiu)接(jie)著往下看。

電(dian)伴(ban)熱(re)VS蒸汽（熱(re)水），電(dian)伴(ban)熱(re)好在哪(na)？

　　電(dian)伴(ban)(ban)熱(re)(re)(re)是(shi)一(yi)種(zhong)有(you)效的(de)管道保溫及防凍(dong)方(fang)(fang)案(an)，一(yi)直被(bei)大(da)(da)批量(liang)應用(yong)。電(dian)伴(ban)(ban)熱(re)(re)(re)溫度梯度小，熱(re)(re)(re)穩定時間(jian)較長(chang)，適合長(chang)期使用(yong)，其所需的(de)熱(re)(re)(re)量(liang)(電(dian)功(gong)率(lv))大(da)(da)大(da)(da)低于電(dian)加(jia)熱(re)(re)(re)。電(dian)伴(ban)(ban)熱(re)(re)(re)具有(you)熱(re)(re)(re)，節(jie)約能源，設計簡(jian)單，施工(gong)安裝方(fang)(fang)便，沒有(you)污染(ran)，使用(yong)壽命長(chang)，能實現遙(yao)控(kong)和自動(dong)控(kong)制等優點，是(shi)取代(dai)蒸汽，熱(re)(re)(re)水伴(ban)(ban)熱(re)(re)(re)的(de)技術(shu)發(fa)展方(fang)(fang)向，是(shi)著重推廣(guang)的(de)節(jie)能項目。其工(gong)作(zuo)(zuo)原理是(shi)通過(guo)伴(ban)(ban)熱(re)(re)(re)媒體散(san)發(fa)一(yi)定的(de)熱(re)(re)(re)量(liang)，通過(guo)直接或間(jian)接的(de)熱(re)(re)(re)交換(huan)補(bu)(bu)充被(bei)伴(ban)(ban)熱(re)(re)(re)管道的(de)損失，以(yi)達到升溫、保溫或防凍(dong)的(de)正(zheng)常工(gong)作(zuo)(zuo)要求(qiu)。電(dian)伴(ban)(ban)熱(re)(re)(re)是(shi)用(yong)電(dian)熱(re)(re)(re)的(de)能量(liang)來補(bu)(bu)充被(bei)伴(ban)(ban)熱(re)(re)(re)體在工(gong)藝流程中所散(san)失的(de)熱(re)(re)(re)量(liang)，從(cong)而維(wei)持流動(dong)介(jie)質合理的(de)工(gong)藝溫度，它是(shi)一(yi)種(zhong)高新技術(shu)產品。

　　伴(ban)(ban)熱(re)(re)帶(dai)(dai)(自(zi)(zi)限溫(wen)(wen)伴(ban)(ban)熱(re)(re)帶(dai)(dai))是新一(yi)代帶(dai)(dai)狀恒溫(wen)(wen)電(dian)(dian)(dian)(dian)(dian)加熱(re)(re)器，其發熱(re)(re)原(yuan)件的(de)電(dian)(dian)(dian)(dian)(dian)阻率具(ju)有很(hen)高(gao)(gao)的(de)正(zheng)溫(wen)(wen)度系數“PTC”且相互并聯。特(te)點(dian)(dian)是：能夠自(zi)(zi)動限制加熱(re)(re)時的(de)溫(wen)(wen)度，并隨被加熱(re)(re)體(ti)的(de)溫(wen)(wen)度自(zi)(zi)動調節輸出(chu)功率而無(wu)任何附加設備;可以任意裁短(duan)或在一(yi)定長(chang)度范圍內接(jie)長(chang)使用，并允許多次交叉重疊而無(wu)高(gao)(gao)溫(wen)(wen)過(guo)熱(re)(re)點(dian)(dian)及(ji)燒毀之慮。這些特(te)點(dian)(dian)使自(zi)(zi)限溫(wen)(wen)伴(ban)(ban)熱(re)(re)帶(dai)(dai)具(ju)有：防止過(guo)熱(re)(re)，使用維護簡便及(ji)節約電(dian)(dian)(dian)(dian)(dian)能等特(te)點(dian)(dian)。 　　電(dian)(dian)(dian)(dian)(dian)熱(re)(re)帶(dai)(dai)(恒功率電(dian)(dian)(dian)(dian)(dian)熱(re)(re)帶(dai)(dai))的(de)工作原(yuan)理是，電(dian)(dian)(dian)(dian)(dian)源母(mu)(mu)線(xian)(xian)為二根(gen)平行絕(jue)緣銅線(xian)(xian)，在絕(jue)緣層中間纏繞電(dian)(dian)(dian)(dian)(dian)熱(re)(re)絲(si)，并將該電(dian)(dian)(dian)(dian)(dian)熱(re)(re)絲(si)每隔一(yi)定距離(即"發熱(re)(re)節長(chang)")與母(mu)(mu)線(xian)(xian)連接(jie)，形成(cheng)連續并聯電(dian)(dian)(dian)(dian)(dian)阻。母(mu)(mu)線(xian)(xian)通電(dian)(dian)(dian)(dian)(dian)后(hou)，各并聯電(dian)(dian)(dian)(dian)(dian)阻發熱(re)(re)，因而形成(cheng)一(yi)條連續的(de)加熱(re)(re)帶(dai)(dai)。

電(dian)(dian)(dian)(dian)伴熱(re)帶根(gen)據結構的(de)(de)(de)不(bu)同(tong)，有(you)(you)著不(bu)同(tong)的(de)(de)(de)分類，不(bu)同(tong)的(de)(de)(de)電(dian)(dian)(dian)(dian)伴熱(re)帶有(you)(you)著自身(shen)的(de)(de)(de)特性和適用的(de)(de)(de)區(qu)域。電(dian)(dian)(dian)(dian)伴熱(re)帶雖(sui)然都作為保(bao)溫材料，但不(bu)同(tong)區(qu)域對電(dian)(dian)(dian)(dian)伴熱(re)帶的(de)(de)(de)要求不(bu)同(tong)，這也(ye)是電(dian)(dian)(dian)(dian)伴熱(re)帶有(you)(you)很多(duo)分類的(de)(de)(de)原因所在。具體(ti)有(you)(you)哪些分類，接著來看。

　　根據(ju)高(gao)分子PTC材料的組(zu)成不(bu)同，自控溫(wen)加熱(re)電纜分為低(di)溫(wen)型和高(gao)溫(wen)型兩類。

　　市(shi)場(chang)上常見的(de)(de)(de)(de)有以(yi)聚烯烴(jing)為(wei)(wei)(wei)基(ji)材的(de)(de)(de)(de)65℃溫(wen)(wen)度(du)(du)等(deng)(deng)(deng)(deng)級(ji)(ji)的(de)(de)(de)(de)加(jia)(jia)熱電(dian)(dian)(dian)纜(lan)(lan)(lan)和以(yi)含氟材料為(wei)(wei)(wei)基(ji)材的(de)(de)(de)(de)110℃和150℃加(jia)(jia)熱電(dian)(dian)(dian)纜(lan)(lan)(lan)。此處(chu)的(de)(de)(de)(de)溫(wen)(wen)度(du)(du)等(deng)(deng)(deng)(deng)級(ji)(ji)定義為(wei)(wei)(wei)加(jia)(jia)熱電(dian)(dian)(dian)纜(lan)(lan)(lan)所能(neng)(neng)有效應(ying)用(yong)的(de)(de)(de)(de)高(gao)環境(jing)溫(wen)(wen)度(du)(du)。也可(ke)(ke)以(yi)理解(jie)為(wei)(wei)(wei)電(dian)(dian)(dian)纜(lan)(lan)(lan)能(neng)(neng)夠長期穩定應(ying)用(yong)并產生有效加(jia)(jia)熱功率(lv)輸(shu)出(chu)的(de)(de)(de)(de)高(gao)環境(jing)溫(wen)(wen)度(du)(du)，超(chao)過規定溫(wen)(wen)度(du)(du)等(deng)(deng)(deng)(deng)級(ji)(ji)，一(yi)方(fang)面由于(yu)(yu)(yu)電(dian)(dian)(dian)阻，電(dian)(dian)(dian)纜(lan)(lan)(lan)本(ben)身的(de)(de)(de)(de)輸(shu)出(chu)功率(lv)很小，實際加(jia)(jia)熱效率(lv)很低。另一(yi)方(fang)面，長期的(de)(de)(de)(de)超(chao)溫(wen)(wen)使(shi)(shi)用(yong)，使(shi)(shi)電(dian)(dian)(dian)纜(lan)(lan)(lan)性(xing)能(neng)(neng)如：PTC特性(xing)，加(jia)(jia)熱功率(lv)等(deng)(deng)(deng)(deng)劣化或衰(shuai)減，會(hui)降低電(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)(de)使(shi)(shi)用(yong)壽命和運行(xing)可(ke)(ke)靠性(xing)。但短(duan)期間(jian)斷地暴(bao)露于(yu)(yu)(yu)超(chao)過溫(wen)(wen)度(du)(du)等(deng)(deng)(deng)(deng)極(ji)的(de)(de)(de)(de)溫(wen)(wen)度(du)(du)環境(jing)，也是(shi)可(ke)(ke)以(yi)的(de)(de)(de)(de)。因此，除(chu)上述溫(wen)(wen)度(du)(du)等(deng)(deng)(deng)(deng)級(ji)(ji)外(wai)，自控溫(wen)(wen)加(jia)(jia)熱電(dian)(dian)(dian)線，還有另一(yi)個(ge)溫(wen)(wen)度(du)(du)等(deng)(deng)(deng)(deng)級(ji)(ji)。如對(dui)(dui)(dui)于(yu)(yu)(yu)65℃溫(wen)(wen)度(du)(du)等(deng)(deng)(deng)(deng)級(ji)(ji)的(de)(de)(de)(de)電(dian)(dian)(dian)纜(lan)(lan)(lan)，該溫(wen)(wen)度(du)(du)等(deng)(deng)(deng)(deng)級(ji)(ji)為(wei)(wei)(wei)85℃，對(dui)(dui)(dui)于(yu)(yu)(yu)110℃溫(wen)(wen)度(du)(du)等(deng)(deng)(deng)(deng)級(ji)(ji)的(de)(de)(de)(de)電(dian)(dian)(dian)纜(lan)(lan)(lan)，為(wei)(wei)(wei)130℃，而對(dui)(dui)(dui)于(yu)(yu)(yu)150℃電(dian)(dian)(dian)纜(lan)(lan)(lan)，則為(wei)(wei)(wei)230℃。然而此時的(de)(de)(de)(de)電(dian)(dian)(dian)纜(lan)(lan)(lan)有效輸(shu)出(chu)功率(lv)已(yi)接近(jin)于(yu)(yu)(yu)零(ling)。
