所以透明外面罩必須具備優(yōu)異的耐光性能，不變黃，不龜裂，同時(shí)還要保持良好的透光度，且耐刮擦。PC材料雖具有一定程度的耐光性能，但是若要求長(zhǎng)時(shí)間的戶外使用，其耐候性仍然不能滿足使用要求；另外，其表面硬度較低，鉛筆硬度只有1～2H等級(jí)，在使用過(guò)程中容易擦傷，刮花，從而影響透光效果，因此在汽車(chē)外部燈具外面罩使用傳統(tǒng)透明PC材料時(shí)，必須在PC外面罩上噴UV漆后才能滿足該產(chǎn)品的相應(yīng)要求。但傳統(tǒng)PC面罩外噴UV漆這種工藝，存在以下問(wèn)題。存在問(wèn)題1、對(duì)于可直接噴涂UV漆的面罩，噴涂會(huì)導(dǎo)致燈具材料成本的增加以及生產(chǎn)線投資、維護(hù)成本及人工成本的增加；2、對(duì)于透明PC材料和其他材料雙色注塑成型這種設(shè)計(jì)，若只在面罩的PC部分噴涂UV漆，UV漆邊界難以控制（特別是對(duì)于大尺寸、易變形的零件），影響外觀效果，且會(huì)導(dǎo)致廢品率增加；非噴涂部位需遮擋掛具，且對(duì)掛具精度要求較高，導(dǎo)致生產(chǎn)成本增加；若面罩和其他部分全部噴涂UV漆，因不同的材料特性，會(huì)導(dǎo)致零件的不同材料區(qū)域外觀、性能差異/缺陷，尤其是長(zhǎng)時(shí)間使用后差異/缺陷更明顯；對(duì)其再進(jìn)行其他工藝處理時(shí)，會(huì)導(dǎo)致處理后面罩的質(zhì)量下降，甚至因UV漆的存在，無(wú)法實(shí)現(xiàn)其他工藝處理，比如對(duì)多組份面罩噴涂UV漆后。韓國(guó)樂(lè)天，PC-1100U,耐候，抗紫外線，透明，高剛性，高抗沖。常州正規(guī)PC商家</p><p
