在我們接觸客戶過程中，有客戶咨詢我們脫水污泥罐體電伴熱防凍保溫項目，罐體相關參數如下：罐體直徑5米，高度4米，從罐體底部罐體頂部均需保溫，罐頂加保溫；罐體壁外鋪設60mm厚巖棉保溫及鍍鋅板；罐體物料為脫水污泥，要求物料溫度不低于5℃，罐體外部極端低溫按照零下12℃考慮；罐體材質為Q235。

  根據客戶所給出的(de)參數條件和要求，我們技術人員為(wei)其推(tui)薦使(shi)用阻(zu)(zu)燃低溫(wen)(wen)(wen)(wen)(wen)加強型自(zi)限(xian)(xian)溫(wen)(wen)(wen)(wen)(wen)電(dian)(dian)伴(ban)(ban)(ban)熱(re)帶。自(zi)限(xian)(xian)溫(wen)(wen)(wen)(wen)(wen)電(dian)(dian)伴(ban)(ban)(ban)熱(re)帶“PTC”特(te)性(xing)正(zheng)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)系數效(xiao)應，是指材料電(dian)(dian)阻(zu)(zu)率(lv)隨著溫(wen)(wen)(wen)(wen)(wen)度(du)(du)升(sheng)高(gao)而增大，并在(zai)一(yi)定溫(wen)(wen)(wen)(wen)(wen)度(du)(du)區間電(dian)(dian)阻(zu)(zu)率(lv)急劇增大的(de)特(te)性(xing)，可以(yi)任(ren)意截短或(huo)在(zai)一(yi)定范圍內接長使(shi)用，并允(yun)許多次交(jiao)叉重疊而無低溫(wen)(wen)(wen)(wen)(wen)熱(re)點及燒毀(hui)之慮。自(zi)限(xian)(xian)溫(wen)(wen)(wen)(wen)(wen)電(dian)(dian)伴(ban)(ban)(ban)熱(re)帶鍍錫銅絲的(de)編織層覆(fu)蓋率(lv)達(da)到80%，能夠更(geng)(geng)好(hao)的(de)起到防(fang)爆和抗外力的(de)作用，屏(ping)蔽效(xiao)果更(geng)(geng)好(hao)。另(ling)外，自(zi)限(xian)(xian)溫(wen)(wen)(wen)(wen)(wen)電(dian)(dian)伴(ban)(ban)(ban)熱(re)帶外護(hu)套采用了聚(ju)烯烴護(hu)套，具有防(fang)護(hu)的(de)保溫(wen)(wen)(wen)(wen)(wen)性(xing)能，也大大提高(gao)了防(fang)腐防(fang)潮(chao)濕性(xing)能。

  自限(xian)溫電伴熱帶安(an)裝比較方便(bian)，溫度(du)均勻，不會過熱，安(an)全(quan)可靠；節約電能(neng)；間(jian)歇操作時，升溫啟(qi)動快速(su)；安(an)裝及運行費(fei)用低；安(an)裝使用維護簡(jian)便(bian)；便(bian)于自動化管(guan)理；無環(huan)境污染；使用壽命長等特點。
