復合層自粘性漆包線

以(yi)薄絕(jue)(jue)緣(yuan)合(he)(he)(he)成(cheng)(cheng)漆(qi)(qi)包(bao)線(xian)(xian)作為芯線(xian)(xian)，用聚乙泡醇縮丁醛酚—醛樹脂體(ti)系的熱固性自(zi)(zi)粘(zhan)漆(qi)(qi)膜層作為外層的自(zi)(zi)粘(zhan)性漆(qi)(qi)包(bao)線(xian)(xian)。用這種漆(qi)(qi)包(bao)線(xian)(xian)所(suo)繞成(cheng)(cheng)的線(xian)(xian)圈在125℃的條(tiao)件下烘烤一定的時間或通以(yi)大電(dian)流(liu)后， 線(xian)(xian)圈便能自(zi)(zi)行粘(zhan)合(he)(he)(he)成(cheng)(cheng)型，因而可以(yi)省去(qu)線(xian)(xian)圈的絕(jue)(jue)緣(yuan)漆(qi)(qi)浸漬工(gong)序，減少(shao)材料(liao)和工(gong)時消耗(hao)，加速周轉期(qi)，提高勞動生產率。復合(he)(he)(he)層自(zi)(zi)粘(zhan)性漆(qi)(qi)包(bao)線(xian)(xian)屬(shu)于(yu)級絕(jue)(jue)緣(yuan)。

1、銅包(bao)鋁技術因(yin)(yin)其材料上(shang)不是(shi)用的(de)(de)純銅，因(yin)(yin)此在價格上(shang)比較低，在重量(liang)上(shang)因(yin)(yin)為(wei)電線常常需要的(de)(de)計量(liang)單位是(shi)米而不是(shi)重量(liang)，因(yin)(yin)此比較節省(sheng)運輸(shu)成(cheng)本(ben)。

2、由于高(gao)頻信(xin)號具(ju)有“趨膚效應”的特點(dian)，絞(jiao)線(xian)(xian)報價，因(yin)此銅(tong)包鋁線(xian)(xian)和(he)銅(tong)包鋼(gang)線(xian)(xian)在(zai)傳(chuan)輸(shu)高(gao)頻信(xin)號（大于5MHz）時，具(ju)有與純銅(tong)線(xian)(xian)相(xiang)同的導電性(xing)能。

2、因(yin)為鋁容易氧(yang)化，因(yin)此在電線(xian)容易發熱(re)的場(chang)所(suo)中不建議用(yong)銅(tong)包鋁線(xian)，絞線(xian)廠(chang)家，民(min)用(yong)建筑設計規范要求(qiu)的，有(you)耐高(gao)溫及嚴格要求(qiu)場(chang)所(suo)必須采(cai)用(yong)銅(tong)芯電纜。因(yin)此在商場(chang)上常用(yong)銅(tong)包鋁代替鋁線(xian)，很(hen)少用(yong)銅(tong)包鋁代替銅(tong)線(xian)。

自粘性漆包線的結構

自(zi)粘(zhan)(zhan)性(xing)(xing)漆(qi)(qi)包(bao)線(xian)(xian)兒乎均(jun)采用復(fu)合(he)層(ceng)結(jie)(jie)構，泰州絞線(xian)(xian)，即在(zai)一般漆(qi)(qi)包(bao)線(xian)(xian)(基線(xian)(xian))外(wai)，涂(tu)覆自(zi)粘(zhan)(zhan)性(xing)(xing)漆(qi)(qi)(自(zi)粘(zhan)(zhan)層(ceng))。目前國外(wai)對復(fu)合(he)層(ceng)漆(qi)(qi)包(bao)線(xian)(xian)相(xiang)當(dang)重視(shi)，品種多、性(xing)(xing)能(neng)(neng)好。由于復(fu)合(he)層(ceng)漆(qi)(qi)包(bao)線(xian)(xian)是由兩(liang)層(ceng)(或三層(ceng))不(bu)同(tong)材(cai)料(liao)的(de)(de)(de)漆(qi)(qi)涂(tu)制而成，因此與(yu)同(tong)一材(cai)料(liao)的(de)(de)(de)單一涂(tu)層(ceng)漆(qi)(qi)包(bao)線(xian)(xian)相(xiang)比，復(fu)合(he)線(xian)(xian)兼具(ju)了兩(liang)種不(bu)同(tong)材(cai)料(liao)的(de)(de)(de)各自(zi)性(xing)(xing)能(neng)(neng)，克服了由同(tong)一材(cai)料(liao)帶來(lai)的(de)(de)(de)性(xing)(xing)能(neng)(neng)上的(de)(de)(de)不(bu)足。復(fu)合(he)層(ceng)自(zi)粘(zhan)(zhan)性(xing)(xing)漆(qi)(qi)包(bao)線(xian)(xian)結(jie)(jie)構中，基線(xian)(xian)是整(zheng)線(xian)(xian)的(de)(de)(de)主絕(jue)緣(yuan)部分，從一定意義上來(lai)說(復(fu)合(he)效(xiao)應(ying)除外(wai))，它保證了自(zi)粘(zhan)(zhan)性(xing)(xing)漆(qi)(qi)包(bao)線(xian)(xian)的(de)(de)(de)絕(jue)緣(yuan)性(xing)(xing)能(neng)(neng);自(zi)粘(zhan)(zhan)層(ceng)則(ze)主要是為了滿足線(xian)(xian)圈成型工藝的(de)(de)(de)需要，起粘(zhan)(zhan)合(he)作用并(bing)對基線(xian)(xian)有(you)保護(hu)和增(zeng)強的(de)(de)(de)作用(復(fu)合(he)效(xiao)應(ying)對漆(qi)(qi)包(bao)線(xian)(xian)綜合(he)性(xing)(xing)能(neng)(neng)的(de)(de)(de)影響。
