淺(qian)談背膠銅箔的外形分類

背(bei)(bei)(bei)膠(jiao)銅(tong)(tong)箔：以銅(tong)(tong)箔的(de)外(wai)(wai)形(xing)分(fen)(fen)有裸銅(tong)(tong)和背(bei)(bei)(bei)膠(jiao)兩(liang)種：背(bei)(bei)(bei)膠(jiao)銅(tong)(tong)箔表面有覆蓋一層(ceng)麥拉膠(jiao)帶(dai)的(de)為背(bei)(bei)(bei)膠(jiao)銅(tong)(tong)箔，黃(huang)銅(tong)(tong)帶(dai)，反之為裸銅(tong)(tong)；以在變(bian)(bian)壓器中的(de)位置(zhi)不同分(fen)(fen)為內銅(tong)(tong)和外(wai)(wai)銅(tong)(tong)。裸銅(tong)(tong)一般用(yong)于變(bian)(bian)器的(de)外(wai)(wai)銅(tong)(tong)。背(bei)(bei)(bei)膠(jiao)銅(tong)(tong)箔在變(bian)(bian)壓器中一般起屏蔽作用(yong)，主要是減小漏感，銅(tong)(tong)帶(dai)，激磁電流，在繞組所通過的(de)電流過高時，取代銅(tong)(tong)線，起導(dao)體的(de)作用(yong)。

背膠(jiao)(jiao)銅(tong)(tong)箔用(yong)銅(tong)(tong)帶(dai)(dai)纏(chan)(chan)繞變(bian)壓器線(xian)圈有下(xia)列優點：1、絕(jue)緣層材(cai)料膨脹系數與銅(tong)(tong)導體(ti)接(jie)近，2、背膠(jiao)(jiao)銅(tong)(tong)箔的銅(tong)(tong)帶(dai)(dai)導電(dian)、導熱、散熱性能好，3、短路強度高(gao)（銅(tong)(tong)的熔點高(gao))，4、加(jia)(jia)在絕(jue)緣層材(cai)上應力小（純(chun)銅(tong)(tong)易于(yu)彎曲(qu)加(jia)(jia)工）5、材(cai)料利用(yong)率高(gao)，6、易焊接(jie)，7、纏(chan)(chan)繞線(xian)圈時，絕(jue)緣體(ti)與銅(tong)(tong)帶(dai)(dai)同時進行纏(chan)(chan)繞操作方便、時間少、。

采用銅箔焊引線(xian)充放電(dian)循環壽(shou)命(ming)長

銅(tong)(tong)(tong)箔(bo)(bo)焊引線采用(yong)該(gai)電(dian)解(jie)銅(tong)(tong)(tong)箔(bo)(bo)所(suo)(suo)制成(cheng)的(de)充(chong)放電(dian)循(xun)環壽命長、過充(chong)電(dian)時產(chan)生斷裂的(de)二次(ci)電(dian)池集電(dian)體(ti)用(yong)電(dian)解(jie)銅(tong)(tong)(tong)箔(bo)(bo)；該(gai)電(dian)解(jie)銅(tong)(tong)(tong)箔(bo)(bo)的(de)析出面(mian)表面(mian)非(fei)(fei)常(chang)平滑(hua)、并且(qie)(qie)晶體(ti)組(zu)織(zhi)(zhi)非(fei)(fei)常(chang)細(xi)微(wei)，同時常(chang)溫抗(kang)(kang)拉強(qiang)(qiang)度不(bu)過高(gao)，延伸率良好，經熱(re)處理后也(ye)(ye)無(wu)熱(re)軟化(hua)現象并保持恒定(ding)的(de)強(qiang)(qiang)度，高(gao)溫氣氛中的(de)延伸率也(ye)(ye)高(gao)。電(dian)解(jie)銅(tong)(tong)(tong)箔(bo)(bo)析出面(mian)的(de)表面(mian)粗(cu)糙(cao)(cao)度，即常(chang)溫下晶體(ti)組(zu)織(zhi)(zhi)的(de)十點平均(jun)粗(cu)糙(cao)(cao)度Rz小(xiao)于2.5μm，且(qie)(qie)底層(ceng)表面(mian)突(tu)起的(de)小(xiao)峰間距在(zai)(zai)5μm以上(shang)。另外，銅(tong)(tong)(tong)帶價(jia)格，所(suo)(suo)述電(dian)解(jie)銅(tong)(tong)(tong)箔(bo)(bo)的(de)常(chang)溫抗(kang)(kang)拉強(qiang)(qiang)度在(zai)(zai)40kg/mm2以下，于130℃進行15小(xiao)時熱(re)處理后的(de)常(chang)溫抗(kang)(kang)拉強(qiang)(qiang)度的(de)減少率在(zai)(zai)15％以內。少量在(zai)(zai)陽極(ji)表面(mian)沉(chen)積，特別是(shi)對陽極(ji)的(de)電(dian)流(liu)分布有很大(da)影響，造(zao)成(cheng)銅(tong)(tong)(tong)箔(bo)(bo)均(jun)勻度變(bian)差，對12微(wei)米左右的(de)銅(tong)(tong)(tong)箔(bo)(bo)來講，影響較大(da)。

銅箔膠帶你了解嗎？

銅(tong)(tong)箔膠(jiao)(jiao)(jiao)帶(dai)(dai)(dai)是一種(zhong)金屬膠(jiao)(jiao)(jiao)帶(dai)(dai)(dai)，主(zhu)要應用于電(dian)磁(ci)屏(ping)(ping)(ping)(ping)蔽，紫銅(tong)(tong)帶(dai)(dai)(dai)價格，分電(dian)屏(ping)(ping)(ping)(ping)蔽和(he)磁(ci)屏(ping)(ping)(ping)(ping)蔽兩種(zhong)，屏(ping)(ping)(ping)(ping)蔽主(zhu)要是依靠銅(tong)(tong)本身優異的(de)導(dao)電(dian)性能，而磁(ci)屏(ping)(ping)(ping)(ping)蔽則需要銅(tong)(tong)箔膠(jiao)(jiao)(jiao)帶(dai)(dai)(dai)的(de)膠(jiao)(jiao)(jiao)面(mian)導(dao)電(dian)物質“鎳(nie)”來(lai)達到磁(ci)屏(ping)(ping)(ping)(ping)蔽的(de)作用，因而被廣泛(fan)應用于手機(ji)，筆記電(dian)腦和(he)其他(ta)數碼產(chan)品之中。

銅箔具有低表面氧氣特性(xing)，可(ke)以附(fu)著與各(ge)種不同基材(cai)，如金屬，絕緣材(cai)料等，擁(yong)有較寬的溫度使用(yong)范圍。主要應用(yong)于電(dian)磁屏蔽(bi)及(ji)抗靜電(dian)，將導電(dian)銅箔置于襯底面，結合金屬基材(cai)，具有優(you)良的導通性(xing)，并提供電(dian)磁屏蔽(bi)的效(xiao)果。
