What is the difference between thermal transfer and roll coating of aluminum veneer?

Aluminum veneer thermal transfer processas follows (for flat substrates)

第一步:选取已经喷涂或电泳好了的基材
第二步:将木纹热转印纸正面与被转印基材的正面对铺
第三步:平板热转印机加压、加热,通常转印的温度为160180,时间为1825
第四步:撕下热转印纸,使用PET热转印膜转印:适用于异形基材
第五步:用PET热转印膜把被转印的基材包裹住,用超声波封口机把PET热转印膜封成管状袋子。(注:PET热转印膜正面要与被转印基材的被转印面对贴。)
第六步:从管状PET热转印膜袋子的两头抽真空,直至PET热转印膜能充分、有效地紧贴基材。真空的负压大小应根据被转印基材的特征和PET热转印膜所能承受的负压等因素做适当调整,通常在0.30.8Mpa之间
第七步:将已经包裹好的基材送至烘箱烘烤,烘烤温度的高低和时间的长短应根据被转印基材的特征、要转印纹理的深浅及烘箱的具体性能等综合因素做适当调整,通常转印的温度为160180,时间为58分钟
第八步:从烘箱中取出已被转印的基材,用手工或机械吹气(即用吹气的方式将PET热转印膜管状袋吹爆)的方式除下PET热转印膜。Aluminum veneer 1
铝板滚涂工艺如下:
辊涂涂装是以涂装辊作为涂料的载体,涂料在涂装辊表面形成一定厚度的湿膜,借助涂装辊在转动过程中与被涂物接触,将涂料涂覆在被涂物表面。辊涂适宜于金属平板的涂布,尤其适合于金属卷材的高速涂装。辊涂要求涂料具有良好的流平性、湿润性和附着力,有一定的硬度、柔韧性和耐磨性,并具有良好的耐候性与耐玷污性,烘烤固化成膜速度快。辊涂涂装具有以下特点:
①高速自动化涂装作业,涂装速度快,生产效率高,线速度一般都在60 m/min以上,最高可达244 m/min(目前国产设备涂装线速度一般为10~ 60m/min);
②不产生漆雾,涂料利用率接近100 percent
③适用于各种粘度的涂料,漆膜厚度可以准确地控制,厚度均匀一致;
④可正、反面同时涂布。
但辊涂只适应平面涂装,不适应Other形状的被涂物。由于辊涂机采用统一的涂料循环输送、回收系统,涂料的投入量大,不适宜多品种、小批量生产;涂料是在涂装辊表面以湿膜形式转移至被涂物表面,溶剂挥发快,辊涂过程中涂料黏度容易产生变化,若工艺条件控制不当,涂膜容易产生辊痕。
