?紫外光交聯法

　　G.Oster于1958 年首次提出了光(guang)(guang)(guang)(guang)敏化交聯(lian)(lian)(lian)(lian)方(fang)法(fa)，即通過光(guang)(guang)(guang)(guang)引發(fa)劑吸收紫(zi)外光(guang)(guang)(guang)(guang)能量(liang)后(hou)(hou)轉變為激發(fa)態，然后(hou)(hou)在(zai)(zai)聚乙(yi)(yi)烯(xi)鏈(lian)上奪氫(qing)產生(sheng)自(zi)由(you)基熱引發(fa)聚乙(yi)(yi)烯(xi)交聯(lian)(lian)(lian)(lian)：) 20 世紀80 年代以后(hou)(hou)，B . Rallby 及(ji)其合(he)作(zuo)者在(zai)(zai)聚乙(yi)(yi)烯(xi)的紫(zi)外光(guang)(guang)(guang)(guang)交聯(lian)(lian)(lian)(lian)研(yan)究(jiu)方(fang)面(mian)取得(de)了一些突(tu)破性進展。中國科技(ji)(ji)大學將光(guang)(guang)(guang)(guang)交聯(lian)(lian)(lian)(lian)技(ji)(ji)術(shu)應用(yong)于制(zhi)造電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜絕緣材料，創建了*條光(guang)(guang)(guang)(guang)交聯(lian)(lian)(lian)(lian)聚乙(yi)(yi)烯(xi)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜試生(sheng)產線(xian)(xian)(xian)并申請了專利。光(guang)(guang)(guang)(guang)交聯(lian)(lian)(lian)(lian)在(zai)(zai)技(ji)(ji)術(shu)原理(li)上類似于高能電(dian)(dian)(dian)子束輻射(she)法(fa)，但(dan)是它采用(yong)低能的紫(zi)外光(guang)(guang)(guang)(guang)作(zuo)為輻射(she)源。設備(bei)易得(de)，投資費用(yong)低，操作(zuo)簡(jian)單，防護(hu)容易。因此(ci)，聚乙(yi)(yi)烯(xi)紫(zi)外光(guang)(guang)(guang)(guang)交聯(lian)(lian)(lian)(lian)技(ji)(ji)術(shu)越來(lai)越受到人們的重視，特別(bie)是在(zai)(zai)發(fa)展交聯(lian)(lian)(lian)(lian)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜方(fang)面(mian)具(ju)有一定的市(shi)場潛(qian)力。
