聚酯漆包線

50年(nian)代(dai)中由西(xi)德首(shou)先研(yan)制成功以對苯二甲酸(suan)二甲酯為(wei)(wei)基的(de)聚(ju)(ju)酯漆(qi)(qi)(qi)(qi)包(bao)(bao)線(xian)漆(qi)(qi)(qi)(qi)，由于其具有較(jiao)好的(de)耐熱性(xing)和機械強(qiang)度(du)(du)，制漆(qi)(qi)(qi)(qi)工藝幅度(du)(du)寬，價格低廉，銅漆(qi)(qi)(qi)(qi)包(bao)(bao)線(xian)生(sheng)產(chan)廠家(jia)(jia)，從50年(nian)代(dai)起成了主宰漆(qi)(qi)(qi)(qi)包(bao)(bao)線(xian)市場的(de)主要產(chan)品(pin)。但由于聚(ju)(ju)酯漆(qi)(qi)(qi)(qi)包(bao)(bao)線(xian)耐熱沖擊性(xing)差，在(zai)高(gao)溫、高(gao)濕條件下(xia)易(yi)水解(jie)等原因，70年(nian)代(dai)后期(qi)作(zuo)為(wei)(wei)單一涂層的(de)聚(ju)(ju)酯漆(qi)(qi)(qi)(qi)包(bao)(bao)線(xian)在(zai)西(xi)德和美(mei)國(guo)已不再生(sheng)產(chan)，而(er)在(zai)日本，中國(guo)及(ji)東(dong)南亞地區(qu)仍(reng)大(da)量生(sheng)產(chan)和使(shi)用(yong)。1986年(nian)的(de)統(tong)計數(shu)字表明我國(guo)聚(ju)(ju)酯漆(qi)(qi)(qi)(qi)包(bao)(bao)線(xian)的(de)產(chan)量占總產(chan)量的(de)96.4%，銅漆(qi)(qi)(qi)(qi)包(bao)(bao)線(xian)批發，經過10年(nian)的(de)努力，漆(qi)(qi)(qi)(qi)包(bao)(bao)線(xian)的(de)品(pin)種得到了發展(zhan)，銅漆(qi)(qi)(qi)(qi)包(bao)(bao)線(xian)廠家(jia)(jia)，但與(yu)發達(da)國(guo)家(jia)(jia)相(xiang)比差距甚大(da)   。國(guo)內聚(ju)(ju)酯改(gai)性(xing)也做了大(da)量工作(zuo)，THEIC改(gai)性(xing)，亞an改(gai)性(xing)均有研(yan)究與(yu)開發，但由于漆(qi)(qi)(qi)(qi)包(bao)(bao)線(xian)結構調整較(jiao)慢，因此目(mu)前這兩種漆(qi)(qi)(qi)(qi)的(de)生(sheng)產(chan)量仍(reng)不大(da)。到目(mu)前為(wei)(wei)止，改(gai)性(xing)聚(ju)(ju)酯漆(qi)(qi)(qi)(qi)包(bao)(bao)線(xian)的(de)電壓下(xia)降問題仍(reng)需(xu)引起大(da)家(jia)(jia)的(de)重視

性能

由于高頻信號具有“趨膚效應”的(de)(de)特(te)點，因(yin)此銅(tong)(tong)包(bao)(bao)鋁(lv)線(xian)和銅(tong)(tong)包(bao)(bao)鋼線(xian)在(zai)傳輸高頻信號（大于5MHz）時，具有與純(chun)銅(tong)(tong)線(xian)相(xiang)同的(de)(de)導電(dian)性(xing)(xing)(xing)(xing)能。du的(de)(de)復(fu)合(he)性(xing)(xing)(xing)(xing)能：銅(tong)(tong)包(bao)(bao)鋁(lv)線(xian)同時具備(bei)銅(tong)(tong)的(de)(de)導電(dian)性(xing)(xing)(xing)(xing)與鋁(lv)的(de)(de)密(mi)度小的(de)(de)復(fu)合(he)特(te)性(xing)(xing)(xing)(xing)；而銅(tong)(tong)包(bao)(bao)鋼線(xian)則將銅(tong)(tong)的(de)(de)導電(dian)性(xing)(xing)(xing)(xing)與鋼的(de)(de)高強(qiang)度結合(he)在(zai)一起。鍍錫(xi)銅(tong)(tong)包(bao)(bao)鋼線(xian)發(fa)揮了錫(xi)的(de)(de)可(ke)焊性(xing)(xing)(xing)(xing)和抗(kang)硫化(hua)性(xing)(xing)(xing)(xing)；鍍銀銅(tong)(tong)包(bao)(bao)鋼線(xian)則提高了導電(dian)性(xing)(xing)(xing)(xing)、導熱性(xing)(xing)(xing)(xing)、增大了耐蝕性(xing)(xing)(xing)(xing)、抗(kang)yang化(hua)性(xing)(xing)(xing)(xing)。因(yin)而具有廣闊的(de)(de)應用范圍。
