一、什么是紫外線固化燈

紫外線光(guang)（UV）固化(hua)是利用光(guang)引發劑（光(guang)敏劑）的感光(guang)性、在紫外線光(guang)照射下光(guang)引發形成激發生態分子，分解成自由基(ji)或是離子，使不(bu)飽和有機(ji)物(wu)進行聚合(he)、接技(ji)、交聯等化(hua)學(xue)反應達到固化(hua)的目的。

UV固化(hua)燈是中高(gao)壓(ya)汞(gong)燈，紫外線(xian)波長為365nm。高(gao)壓(ya)汞(gong)燈中有(you)的(de)加入金屬(shu)鹵化(hua)物(wu)，改(gai)善其特性，改(gai)善汞(gong)燈的(de)發射光譜和(he)能量(liang)分布(bu)，讓其主波峰變(bian)為365nm，強化(hua)UVA、UVV輸(shu)出，UVC輸(shu)出有(you)所降低，從而用來(lai)進行光固化(hua)。

二、紫外線固化燈管的種類和用途

1、無影膠固化燈

為(wei)低(di)壓氣體放電(dian)燈(deng)，燈(deng)管長度(du)15mm-1800mm，紫外(wai)波(bo)長為(wei)300nm～400nm ,波(bo)峰值為(wei)365nm，光(guang)照強(qiang)(qiang)度(du)都大于4mW/cm2，具(ju)有瞬時(shi)固(gu)化(hua)，省時(shi)省電(dian)，節約空間，容易(yi)控制(zhi)，無(wu)(wu)須高溫烘烤，對基材有廣泛的適應性，無(wu)(wu)污染(ran)等優點。紫外(wai)線固(gu)化(hua)燈(deng)管的用(yong)途主要是作(zuo)為(wei)出版(ban)，影像(xiang)，玻(bo)璃(li)工(gong)(gong)藝，玻(bo)璃(li)家具(ju)，玻(bo)璃(li)移(yi)門，玻(bo)璃(li)寫真，強(qiang)(qiang)化(hua)玻(bo)璃(li)，水晶工(gong)(gong)藝等大面積的粘接，固(gu)定，組(zu)裝等的快速固(gu)化(hua)光(guang)源。

2、UV膠/UV油墨固化燈

為(wei)(wei)高(gao)壓(ya)氣體(ti)放(fang)電燈，作(zuo)(zuo)為(wei)(wei)UV光源使用，其紫外線輸出(chu)主(zhu)峰值為(wei)(wei)365NM，功(gong)率(lv)密度(du)和紫外輸出(chu)很強(qiang)，固化時間短。燈頭(tou)可(ke)作(zuo)(zuo)成頂式、瓷頭(tou)引(yin)出(chu)兩(liang)種，其工作(zuo)(zuo)面較小，適合于印刷制版、軟包裝彩印、家(jia)俱行業、裝飾材料、紙張上(shang)光、汽車及摩托(tuo)塑(su)料零件、印刷制罐(guan)、塑(su)料包裝表面UV油墨、UV上(shang)光油固化、同時還(huan)是半導體(ti)印制線路(lu)板、標牌等行業。

三、uv紫外線固化燈和紫外線殺菌燈有什么區別

紫(zi)外(wai)線(xian)(xian)(xian)殺菌燈(deng)實際(ji)上是屬于(yu)一種低壓(ya)汞(gong)(gong)燈(deng)。低壓(ya)汞(gong)(gong)燈(deng)是利用較低汞(gong)(gong)蒸汽(qi)壓(ya)（<10-2Pa）被激化而發(fa)出(chu)紫(zi)外(wai)光，其發(fa)光譜線(xian)(xian)(xian)主要有兩條(tiao)(tiao)：一條(tiao)(tiao)是253.7nm波長；另(ling)一條(tiao)(tiao)是185nm波長，這兩條(tiao)(tiao)都(dou)是肉眼看不(bu)見的(de)(de)紫(zi)外(wai)線(xian)(xian)(xian)。而紫(zi)外(wai)線(xian)(xian)(xian)固化燈(deng)的(de)(de)功率密度會十分高，不(bu)是普(pu)通(tong)的(de)(de)紫(zi)外(wai)線(xian)(xian)(xian)殺菌燈(deng)管能到(dao)達的(de)(de)。

uv紫外(wai)(wai)線(xian)(xian)(xian)(xian)固化燈(deng)和(he)紫外(wai)(wai)線(xian)(xian)(xian)(xian)消毒燈(deng)的區別還體現在紫外(wai)(wai)線(xian)(xian)(xian)(xian)強度(du)方面，紫外(wai)(wai)線(xian)(xian)(xian)(xian)殺菌(jun)燈(deng)管(guan)(guan)(guan)分低壓燈(deng)管(guan)(guan)(guan)和(he)中壓燈(deng)管(guan)(guan)(guan)，國(guo)標(biao)規定一般65W以下(xia)，發(fa)熱量(liang)小。而做固化用的紫外(wai)(wai)線(xian)(xian)(xian)(xian)光源都是幾百瓦(wa)上(shang)千瓦(wa)的功率，發(fa)熱量(liang)大。

用(yong)(yong)途方面，紫(zi)外(wai)(wai)線(xian)(xian)殺菌燈管主要(yao)用(yong)(yong)于空氣(qi)殺菌，水(shui)(shui)(shui)消毒(du)(du)、物體表(biao)面消毒(du)(du)，按照消毒(du)(du)對象(xiang)不同，通常(chang)分污水(shui)(shui)(shui)紫(zi)外(wai)(wai)線(xian)(xian)消毒(du)(du)器(qi)(qi)(qi)、飲用(yong)(yong)水(shui)(shui)(shui)紫(zi)外(wai)(wai)線(xian)(xian)消毒(du)(du)器(qi)(qi)(qi)、中水(shui)(shui)(shui)紫(zi)外(wai)(wai)線(xian)(xian)消毒(du)(du)器(qi)(qi)(qi)和空氣(qi)紫(zi)外(wai)(wai)線(xian)(xian)消毒(du)(du)器(qi)(qi)(qi)。紫(zi)外(wai)(wai)線(xian)(xian)固(gu)化(hua)燈管主要(yao)用(yong)(yong)于膠(jiao)和油墨(mo)的紫(zi)外(wai)(wai)固(gu)化(hua)、光(guang)化(hua)學反(fan)應(ying)等。
