uv機使(shi)用過程(cheng)中要(yao)(yao)(yao)定(ding)期(qi)更(geng)(geng)(geng)換(huan)(huan)(huan)uv固(gu)化(hua)(hua)燈(deng)(deng)管(guan)(guan)才能(neng)保持照射能(neng)量(liang)足(zu)夠使(shi)加工產品的(de)UV固(gu)化(hua)(hua)效(xiao)果最(zui)佳，uv固(gu)化(hua)(hua)燈(deng)(deng)管(guan)(guan)在使(shi)用中能(neng)量(liang)是逐(zhu)漸(jian)衰(shuai)弱的(de)，直到(dao)(dao)(dao)能(neng)點(dian)亮但(dan)沒(mei)(mei)有(you)UV紫外線(xian)產生，但(dan)要(yao)(yao)(yao)在這(zhe)個之(zhi)前把這(zhe)個uv固(gu)化(hua)(hua)燈(deng)(deng)管(guan)(guan)更(geng)(geng)(geng)換(huan)(huan)(huan)掉才行，一般(ban)(ban)高壓汞燈(deng)(deng)使(shi)用時(shi)間一般(ban)(ban)在八百個小時(shi)到(dao)(dao)(dao)一千個小時(shi)之(zhi)間就要(yao)(yao)(yao)更(geng)(geng)(geng)換(huan)(huan)(huan)uv固(gu)化(hua)(hua)燈(deng)(deng)管(guan)(guan)，如果真使(shi)用到(dao)(dao)(dao)一千個小時(shi)了這(zhe)個已經是到(dao)(dao)(dao)了衰(shuai)竭到(dao)(dao)(dao)沒(mei)(mei)有(you)UV紫外線(xian)產生的(de)這(zhe)個階(jie)段(duan)了，所以(yi)到(dao)(dao)(dao)底使(shi)用多久(jiu)后需要(yao)(yao)(yao)更(geng)(geng)(geng)換(huan)(huan)(huan)燈(deng)(deng)管(guan)(guan)，就要(yao)(yao)(yao)用UV能(neng)量(liang)表對紫外光(guang)源進(jin)行能(neng)量(liang)檢測。當檢測到(dao)(dao)(dao)的(de)能(neng)量(liang)達不到(dao)(dao)(dao)設定(ding)的(de)標準數值(zhi)時(shi)，就需要(yao)(yao)(yao)更(geng)(geng)(geng)換(huan)(huan)(huan)UV燈(deng)(deng)管(guan)(guan)了。
