“中”，銅包(bao)鋁(lv)自(zi)粘漆(qi)包(bao)線(xian)(xian)，“小”，“微細”-聚氨酯(zhi)銅包(bao)鋁(lv)漆(qi)包(bao)線(xian)(xian)特點多說一(yi)說

聚氨(an)(an)酯(zhi)銅(tong)(tong)包鋁(lv)漆(qi)包線(xian)，熱級等級為(wei)130、155、180、200．醉(zui)大(da)特點是(shi)具有直焊性(xing)(xing)(xing)，宿遷(qian)漆(qi)包線(xian)，耐高頻性(xing)(xing)(xing)能性(xing)(xing)(xing)好，易(yi)著色，耐潮性(xing)(xing)(xing)能好，銅(tong)(tong)鋁(lv)漆(qi)包線(xian)，廣泛應于(yu)電子家(jia)電和(he)精密儀(yi)器，電訊(xun)，儀(yi)表(biao)上，聚氨(an)(an)酯(zhi)銅(tong)(tong)包鋁(lv)漆(qi)包線(xian)弱點是(shi)機(ji)械強度稍(shao)差(cha)，耐熱性(xing)(xing)(xing)能不(bu)高，且(qie)生(sheng)產大(da)規格線(xian)的(de)柔韌性(xing)(xing)(xing)和(he)附著性(xing)(xing)(xing)較差(cha)，因此該聚氨(an)(an)酯(zhi)銅(tong)(tong)包鋁(lv)漆(qi)包線(xian)生(sheng)產的(de)規格以(yi)中小及微細線(xian)為(wei)多(duo)。還有QA銅(tong)(tong)包鋁(lv)漆(qi)包線(xian)也(ye)受到(dao)了很多(duo)的(de)關(guan)注呢。

在(zai)退火爐前裝置(zhi)助(zhu)力(li)(li)(li)輪對張(zhang)(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)的(de)操(cao)控(kong)有很大協助(zhu)。軟銅(tong)線(xian)在(zai)室(shi)溫下(xia)其醉大不(bu)(bu)(bu)延(yan)(yan)伸(shen)(shen)張(zhang)(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)約為(wei)15kg/mm2，在(zai)400℃下(xia)醉大不(bu)(bu)(bu)延(yan)(yan)伸(shen)(shen)張(zhang)(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)約為(wei)7kg/mm2；在(zai)460℃下(xia)醉大不(bu)(bu)(bu)延(yan)(yan)伸(shen)(shen)張(zhang)(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)為(wei)4kg/mm2；在(zai)500℃下(xia)醉大不(bu)(bu)(bu)延(yan)(yan)伸(shen)(shen)張(zhang)(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)為(wei)2kg/mm2。在(zai)正常的(de)漆包線(xian)涂制(zhi)過程(cheng)中，漆包線(xian)的(de)張(zhang)(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)要顯著小于不(bu)(bu)(bu)延(yan)(yan)伸(shen)(shen)張(zhang)(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)，需求操(cao)控(kong)在(zai)50%擺布，放線(xian)張(zhang)(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)操(cao)控(kong)在(zai)不(bu)(bu)(bu)延(yan)(yan)伸(shen)(shen)張(zhang)(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)的(de)20%擺布。

大標(biao)準(zhun)大容(rong)量線軸(zhou)通(tong)常(chang)選用(yong)徑向(xiang)旋轉式(shi)(shi)放(fang)線器；中等標(biao)準(zhun)導(dao)(dao)線通(tong)常(chang)選用(yong)越端式(shi)(shi)或毛(mao)刷式(shi)(shi)放(fang)線器；微(wei)細標(biao)準(zhun)導(dao)(dao)線通(tong)常(chang)選用(yong)毛(mao)刷式(shi)(shi)或雙錐套式(shi)(shi)放(fang)線器。

不論(lun)選用哪種(zhong)放線方法，都對(dui)裸銅(tong)線線軸的布局和質量有(you)嚴(yan)格需(xu)求

----外表應(ying)光(guang)亮以確保(bao)線(xian)材不被(bei)擦傷

----軸芯兩邊及側(ce)板內外有(you)2—4mm半(ban)徑的r角(jiao)以(yi)確保(bao)放(fang)線過程中能均衡放(fang)出

----線軸加工完后，必須(xu)作動、靜平衡試驗

----毛刷(shua)放(fang)線(xian)器需求軸芯(xin)直徑(jing)：側板直徑(jing)小于1：1.7；越端放(fang)線(xian)需求小于1：1.9，不然放(fang)線(xian)至軸芯(xin)時會呈現(xian)斷(duan)線(xian)表(biao)象

銅(tong)(tong)(tong)包(bao)鋁(lv)導(dao)(dao)體(ti)(ti)是(shi)按重(zhong)量(liang)出售(shou)的(de)(de)(de)，純(chun)(chun)銅(tong)(tong)(tong)導(dao)(dao)體(ti)(ti)也(ye)是(shi)按重(zhong)量(liang)出售(shou)的(de)(de)(de)，銅(tong)(tong)(tong)包(bao)鋁(lv)導(dao)(dao)體(ti)(ti)的(de)(de)(de)價格要(yao)比相(xiang)同重(zhong)量(liang)的(de)(de)(de)純(chun)(chun)銅(tong)(tong)(tong)導(dao)(dao)體(ti)(ti)貴一(yi)(yi)些。但是(shi)同樣(yang)重(zhong)量(liang)的(de)(de)(de)銅(tong)(tong)(tong)包(bao)鋁(lv)要(yao)比純(chun)(chun)銅(tong)(tong)(tong)導(dao)(dao)體(ti)(ti)長(chang)(chang)度(du)長(chang)(chang)很(hen)多(duo)，而電(dian)纜是(shi)按長(chang)(chang)度(du)計算的(de)(de)(de)。相(xiang)同重(zhong)量(liang)銅(tong)(tong)(tong)包(bao)鋁(lv)線(xian)是(shi)銅(tong)(tong)(tong)線(xian)長(chang)(chang)度(du)的(de)(de)(de)2.5倍(bei)，價格僅僅是(shi)每噸多(duo)幾百元。綜合下來，銅(tong)(tong)(tong)包(bao)鋁(lv)就很(hen)有優勢。由于銅(tong)(tong)(tong)包(bao)鋁(lv)電(dian)纜比較輕(qing)，電(dian)纜的(de)(de)(de)運輸成本、安裝架設成本都(dou)會有所降低，會給施工帶來一(yi)(yi)定(ding)的(de)(de)(de)方便性。
