  • 漆包線與電磁線區別

    電磁線(xian)(xian)使(shi)多種使(shi)用(yong)和(he)(he)(he)制(zhi)(zhi)造工(gong)藝上的(de)要求。前(qian)者包(bao)括其(qi)形狀、規(gui)格、能短時和(he)(he)(he)長期在高溫下工(gong)作,以及(ji)承(cheng)受(shou)(shou)某(mou)些場合中(zhong)的(de)強烈振動和(he)(he)(he)高速下的(de)離心力(li),高電壓下的(de)耐受(shou)(shou)電暈和(he)(he)(he)擊穿,氣氛下的(de)耐化(hua)學腐(fu)蝕(shi)等;后者包(bao)括繞制(zhi)(zhi)和(he)(he)(he)嵌線(xian)(xian)時經受(shou)(shou)拉伸、彎曲和(he)(he)(he)磨損的(de)要求,以及(ji)浸(jin)漬和(he)(he)(he)烘干過程中(zhong)的(de)溶脹、侵蝕(shi)作用(yong)等。   電磁線(xian)(xian)可以按其(qi)基本組成(cheng)、導電線(xian)(xian)心和(he)(he)(he)電絕(jue)(jue)緣(yuan)層分類(lei)。通常根據(ju)電絕(jue)(jue)緣(yuan)層所用(yong)的(de)絕(jue)(jue)緣(yuan)材(cai)料(liao)和(he)(he)(he)制(zhi)(zhi)造方式分為(wei)漆(qi)包(bao)線(xian)(xian)、繞包(bao)線(xian)(xian)、漆(qi)包(bao)繞包(bao)線(xian)(xian)和(he)(he)(he)無機(ji)絕(jue)(jue)緣(yuan)線(xian)(xian)。   漆(qi)包(bao)線(xian)(xian) 在導體外涂以相應的(de)漆(qi)溶液,再經溶劑揮發和(he)(he)(he)漆(qi)膜固(gu)化(hua)、冷卻而制(zhi)(zhi)成(cheng)。漆(qi)包(bao)線(xian)(xian)按其(qi)所用(yong)的(de)絕(jue)(jue)緣(yuan)...

  • 電磁線生產的環保工作

    ??電(dian)磁線(xian)(xian)(xian)(xian)又稱繞(rao)組線(xian)(xian)(xian)(xian),常根據電(dian)層(ceng)所用(yong)的材料(liao)和(he)(he)制造方式分為(wei)漆(qi)(qi)包(bao)(bao)線(xian)(xian)(xian)(xian)、繞(rao)包(bao)(bao)線(xian)(xian)(xian)(xian)、漆(qi)(qi)包(bao)(bao)繞(rao)包(bao)(bao)線(xian)(xian)(xian)(xian)和(he)(he)無機(ji)(ji)(ji)緣(yuan)線(xian)(xian)(xian)(xian)。起初的漆(qi)(qi)包(bao)(bao)線(xian)(xian)(xian)(xian)是由(you)桐油等制成(cheng)的油性(xing)漆(qi)(qi)包(bao)(bao)線(xian)(xian)(xian)(xian),不能直接用(yong)于制造電(dian)機(ji)(ji)(ji)線(xian)(xian)(xian)(xian)圈和(he)(he)繞(rao)組,使(shi)用(yong)時(shi)需(xu)加棉紗(sha)包(bao)(bao)繞(rao)層(ceng)。 后(hou)來聚乙烯醇(chun)縮甲醛漆(qi)(qi)包(bao)(bao)線(xian)(xian)(xian)(xian)問世(shi),其機(ji)(ji)(ji)械(xie)性(xing)能大(da)為(wei)增(zeng)加,可以直接用(yong)于電(dian)機(ji)(ji)(ji)繞(rao)組,而(er)稱為(wei)漆(qi)(qi)包(bao)(bao)線(xian)(xian)(xian)(xian)。 ? ? 隨著(zhu)弱電(dian)的發展又出現了(le)具有自(zi)粘性(xing)漆(qi)(qi)包(bao)(bao)線(xian)(xian)(xian)(xian),可以不用(yong)浸漬、烘焙而(er)獲得整體性(xing)較(jiao)好的線(xian)(xian)(xian)(xian)圈。但其機(ji)(ji)(ji)械(xie)強度較(jiao)差,能有微特(te)電(dian)機(ji)(ji)(ji)、小電(dian)機(ji)(ji)(ji)中(zhong)使(shi)用(yong)。此外為(wei)了(le)焊接時(shi)先行漆(qi)(qi)膜(mo)的麻煩,發展了(le)直焊性(xing)漆(qi)(qi)包(bao)(bao)線(xian)(xian)(xian)(xian),其涂膜(mo)能在高溫搪錫槽(cao)中(zhong)自(zi)行脫(tuo)落而(er)使(shi)銅(tong)...

  • 銅、鋁電磁線簡單鑒別方法

    鋼(gang)材是一個受到市(shi)場調控因(yin)素價格(ge)浮動的(de)(de)(de)(de)(de)(de)產品。由(you)于有色金屬價格(ge),讓很(hen)多(duo)做電(dian)(dian)磁線(xian)銅(tong)(tong)線(xian)生(sheng)意的(de)(de)(de)(de)(de)(de)商家(jia)叫苦連(lian)連(lian),而(er)電(dian)(dian)機(ji)銅(tong)(tong)線(xian)是不可缺的(de)(de)(de)(de)(de)(de)重(zhong)要組(zu)成部(bu)分(fen)。而(er)如今市(shi)場上出現了(le)很(hen)多(duo)采取(qu)鋁(lv)線(xian)代替(ti)銅(tong)(tong)線(xian)的(de)(de)(de)(de)(de)(de)說法,而(er)與之相付的(de)(de)(de)(de)(de)(de)鋁(lv)線(xian)電(dian)(dian)機(ji)也(ye)應運而(er)生(sheng)。那(nei)么(me)銅(tong)(tong)線(xian)電(dian)(dian)機(ji)和鋁(lv)線(xian)電(dian)(dian)機(ji)有哪些區別?如何鑒別呢?實際我們只要從(cong)其金屬的(de)(de)(de)(de)(de)(de)原理就不難分(fen)辨。 ? ? ??1.因(yin)為同等面積的(de)(de)(de)(de)(de)(de)鋁(lv)線(xian)的(de)(de)(de)(de)(de)(de)電(dian)(dian)阻值比銅(tong)(tong)線(xian)高(gao),所以如果在電(dian)(dian)機(ji)的(de)(de)(de)(de)(de)(de)工作(zuo)中想(xiang)獲得相等的(de)(de)(de)(de)(de)(de)電(dian)(dian)流,那(nei)么(me)勢需要要鋁(lv)線(xian)的(de)(de)(de)(de)(de)(de)橫(heng)截面積。 ? ? ??2.由(you)于不同金屬的(de)(de)(de)(de)(de)(de)物理性質不同,鋁(lv)線(xian)不能像(xiang)銅(tong)(tong)線(xian)一樣有那(nei)么(me)好的(de)(de)(de)(de)(de)(de)拉(la)伸性,同...
