我們在購買電伴熱帶(dai)的時候,如(ru)何在眾多的電伴熱帶(dai)中選擇質優的產品呢?下(xia)面就給大家(jia)介紹(shao)一些鑒別方法,希望(wang)對您有幫助:
1、電(dian)伴(ban)熱帶的(de)(de)外(wai)表(biao)皮一般(ban)為PTC塑料,鑒(jian)別PTC材料我(wo)們可以(yi)做一個(ge)燃(ran)燒試驗鑒(jian)別它的(de)(de)好壞。
燃燒實驗:用明(ming)火接觸PTC芯帶,不燃則材(cai)(cai)質好,稱特(te)種PTC材(cai)(cai)料,阻(zu)燃或(huo)可(ke)燃者則材(cai)(cai)料較(jiao)次。
2、從氣味(wei)方面鑒(jian)別電伴熱帶的質(zhi)量是否過關。用明火接觸PTC芯帶,無蠟油(you)煙味(wei)且不燃(ran)材質(zhi)為特種PTC,有(you)蠟油(you)煙味(wei)且可燃(ran)的產品(pin)為普(pu)通PTC,有(you)異味(wei)產品(pin)為普(pu)通阻燃(ran)PTC。
3、剝去電(dian)伴熱產(chan)品(pin)的(de)(de)外(wai)絕(jue)緣護(hu)層,用兆歐表的(de)(de)兩極分別(bie)接觸(chu)導電(dian)線(xian)芯(xin)和PTC芯(xin)帶無法剝離的(de)(de)復合絕(jue)緣護(hu)層表面測試絕(jue)緣電(dian)阻辨別(bie)產(chan)品(pin)質量(liang)。
4、絕緣層及外護套材料(liao),以F46為(wei)好,基材為(wei)聚烯(xi)烴則較次,阻(zu)燃(ran)聚烯(xi)烴分無鹵阻(zu)燃(ran)、低煙低鹵阻(zu)燃(ran)、有(you)鹵阻(zu)燃(ran),阻(zu)燃(ran)分自(zi)熄或不(bu)(bu)延燃(ran)而不(bu)(bu)是不(bu)(bu)燃(ran)等。
5、選取50~100m電伴熱帶通電,兩端及全線(xian)各(ge)點溫(wen)度差(cha)小則溫(wen)度均勻(yun)度好(hao),或者剪斷,各(ge)部(bu)分在同等(deng)條件下測電阻,阻值(zhi)差(cha)別越小說明阻值(zhi)越均勻(yun),產品越好(hao)。
