聚酯漆包線

50年(nian)代中由(you)(you)西(xi)德(de)首先(xian)研制(zhi)成功以對苯二甲酸(suan)二甲酯(zhi)為基的(de)聚(ju)酯(zhi)漆(qi)(qi)(qi)(qi)包(bao)(bao)線(xian)漆(qi)(qi)(qi)(qi)，銅(tong)包(bao)(bao)鋁(lv)電(dian)線(xian)，由(you)(you)于(yu)其具有較(jiao)好的(de)耐熱性(xing)(xing)(xing)和(he)機械(xie)強(qiang)度(du)，制(zhi)漆(qi)(qi)(qi)(qi)工(gong)藝幅度(du)寬，價格低廉，從50年(nian)代起(qi)(qi)成了(le)主宰漆(qi)(qi)(qi)(qi)包(bao)(bao)線(xian)市場(chang)的(de)主要產(chan)品(pin)。但(dan)由(you)(you)于(yu)聚(ju)酯(zhi)漆(qi)(qi)(qi)(qi)包(bao)(bao)線(xian)耐熱沖擊性(xing)(xing)(xing)差，在高溫、高濕條件下易(yi)水解等原(yuan)因，70年(nian)代后期作為單一(yi)涂層的(de)聚(ju)酯(zhi)漆(qi)(qi)(qi)(qi)包(bao)(bao)線(xian)在西(xi)德(de)和(he)美(mei)國已不(bu)再生(sheng)產(chan)，電(dian)鍍(du)銅(tong)包(bao)(bao)鋁(lv)，而在日本(ben)，中國及東南亞地區(qu)仍大量(liang)(liang)生(sheng)產(chan)和(he)使用(yong)。1986年(nian)的(de)統計數字表(biao)明(ming)我國聚(ju)酯(zhi)漆(qi)(qi)(qi)(qi)包(bao)(bao)線(xian)的(de)產(chan)量(liang)(liang)占總產(chan)量(liang)(liang)的(de)96.4%，銅(tong)包(bao)(bao)鋁(lv)電(dian)纜(lan)，經過10年(nian)的(de)努力，漆(qi)(qi)(qi)(qi)包(bao)(bao)線(xian)的(de)品(pin)種(zhong)得到(dao)了(le)發(fa)展，但(dan)與發(fa)達國家相比(bi)差距甚大? ?。國內聚(ju)酯(zhi)改性(xing)(xing)(xing)也做了(le)大量(liang)(liang)工(gong)作，THEIC改性(xing)(xing)(xing)，亞an改性(xing)(xing)(xing)均有研究與開(kai)發(fa)，但(dan)由(you)(you)于(yu)漆(qi)(qi)(qi)(qi)包(bao)(bao)線(xian)結構調整較(jiao)慢，無錫銅(tong)包(bao)(bao)鋁(lv)，因此目(mu)前這兩種(zhong)漆(qi)(qi)(qi)(qi)的(de)生(sheng)產(chan)量(liang)(liang)仍不(bu)大。到(dao)目(mu)前為止，改性(xing)(xing)(xing)聚(ju)酯(zhi)漆(qi)(qi)(qi)(qi)包(bao)(bao)線(xian)的(de)電(dian)壓下降問(wen)題仍需引(yin)起(qi)(qi)大家的(de)重視

聚酯亞an漆包線

聚(ju)酯(zhi)(zhi)亞(ya)(ya)(ya)an漆(qi)(qi)(qi)(qi)包(bao)(bao)(bao)線(xian)(xian)(xian)由(you)于通過對(dui)聚(ju)酯(zhi)(zhi)用(yong)(yong)(yong)亞(ya)(ya)(ya)an進行(xing)改性(xing)(xing)(xing)而提(ti)高了(le)(le)耐(nai)熱性(xing)(xing)(xing)，從70年(nian)代(dai)以后，世界上(shang)聚(ju)酯(zhi)(zhi)亞(ya)(ya)(ya)an漆(qi)(qi)(qi)(qi)包(bao)(bao)(bao)線(xian)(xian)(xian)的(de)(de)用(yong)(yong)(yong)量(liang)急劇上(shang)升，在歐美(mei)該(gai)漆(qi)(qi)(qi)(qi)包(bao)(bao)(bao)線(xian)(xian)(xian)已替(ti)代(dai)單一涂層的(de)(de)聚(ju)酯(zhi)(zhi)漆(qi)(qi)(qi)(qi)包(bao)(bao)(bao)線(xian)(xian)(xian)，目前世界上(shang)具有(you)代(dai)表性(xing)(xing)(xing)的(de)(de)為德國(guo)的(de)(de)Terebe FH系列(lie)(lie)產(chan)(chan)品和美(mei)國(guo)的(de)(de)Isomid系列(lie)(lie)產(chan)(chan)品。同時(shi)還先后研制出直(zhi)焊性(xing)(xing)(xing)聚(ju)酯(zhi)(zhi)亞(ya)(ya)(ya)an漆(qi)(qi)(qi)(qi)包(bao)(bao)(bao)線(xian)(xian)(xian)，已廣(guang)泛用(yong)(yong)(yong)作(zuo)小型電(dian)機的(de)(de)繞組(zu)，簡化(hua)了(le)(le)焊接(jie)工(gong)藝(yi)，降低了(le)(le)電(dian)機制造(zao)成本。日本有(you)些也采(cai)用(yong)(yong)(yong)直(zhi)焊性(xing)(xing)(xing)聚(ju)酯(zhi)(zhi)亞(ya)(ya)(ya)an漆(qi)(qi)(qi)(qi)作(zuo)為彩電(dian)偏(pian)轉線(xian)(xian)(xian)圈用(yong)(yong)(yong)自粘性(xing)(xing)(xing)漆(qi)(qi)(qi)(qi)包(bao)(bao)(bao)線(xian)(xian)(xian)的(de)(de)底漆(qi)(qi)(qi)(qi)，簡化(hua)了(le)(le)工(gong)藝(yi)。國(guo)內(nei)聚(ju)酯(zhi)(zhi)亞(ya)(ya)(ya)an漆(qi)(qi)(qi)(qi)先后從德國(guo)和意大利引進了(le)(le)制造(zao)技術，也有(you)自行(xing)研制成功，但由(you)于原材料的(de)(de)不(bu)穩定等原因，目前國(guo)內(nei)大量(liang)用(yong)(yong)(yong)作(zuo)耐(nai)冷凍劑復(fu)合漆(qi)(qi)(qi)(qi)包(bao)(bao)(bao)線(xian)(xian)(xian)底漆(qi)(qi)(qi)(qi)的(de)(de)聚(ju)酯(zhi)(zhi)亞(ya)(ya)(ya)an漆(qi)(qi)(qi)(qi)仍(reng)依賴著進口。僅少量(liang)的(de)(de)單一涂層聚(ju)酯(zhi)(zhi)亞(ya)(ya)(ya)an漆(qi)(qi)(qi)(qi)包(bao)(bao)(bao)線(xian)(xian)(xian)應用(yong)(yong)(yong)國(guo)產(chan)(chan)漆(qi)(qi)(qi)(qi)，但電(dian)壓不(bu)穩定仍(reng)是生產(chan)(chan)廠擔心的(de)(de)問題，直(zhi)焊性(xing)(xing)(xing)聚(ju)酯(zhi)(zhi)亞(ya)(ya)(ya)an漆(qi)(qi)(qi)(qi)已由(you)電(dian)纜研究所開發成功

聚酰亞an漆包線

聚酰(xian)(xian)亞an是目前有機(ji)類(lei)漆(qi)(qi)(qi)包(bao)線(xian)中耐熱等級zui高(gao)(gao)的(de)漆(qi)(qi)(qi)包(bao)線(xian)漆(qi)(qi)(qi)，其(qi)長期使(shi)(shi)用(yong)(yong)溫(wen)度可(ke)達220°C以上(shang)。該漆(qi)(qi)(qi)由(you)美國于1958年研(yan)制成功。聚酰(xian)(xian)亞an漆(qi)(qi)(qi)包(bao)線(xian)具(ju)有高(gao)(gao)的(de)耐熱性(xing)，良好的(de)耐溶(rong)劑和耐冷凍劑性(xing)能。但(dan)由(you)于成本昂(ang)貴，儲存穩定性(xing)差和具(ju)有毒(du)性(xing)，影響了它的(de)廣泛使(shi)(shi)用(yong)(yong)。目前該漆(qi)(qi)(qi)包(bao)線(xian)使(shi)(shi)用(yong)(yong)某些特殊場合(he)，如煤礦電機(ji)，宇宙(zhou)空間儀器儀表等用(yong)(yong)線(xian)
