Description

一种室内用防腐性天花铝扣板制作工艺
【技术领域】
本发明涉及吊顶的技术领域，特别是天花铝扣板的技术领域。
【背景技术】
随着现代人生活水平的提高，人越来越重视家庭住宅的装修，而天花铝扣板则是装修的一个重要组成部分，铝扣板是以铝合金板材为基底，通过开料，剪角，模压成型得到，铝扣板表面使用各种不同的涂层加工得到各种铝扣板产品，铝扣板，最主要分两种类型，一种是家装集成铝扣板，另一种则是工程铝扣板，家装铝扣板最开始主要以滚涂和磨砂两大系列为主。但铝合金的耐蚀程度取决于氧化膜在不同环境中的稳定性。在干燥大气下，钝化膜不易被破坏，是稳定的。长期暴露在户外大气环境下，会发生局部点蚀。这主要是因为表面沉积灰尘离子后，在灰尘离子下的水膜中金属表面形成缺氧区，导致钝化膜破坏和自钝化能力下降所造成的。在工业大气中保护膜易受到破坏，耐蚀性下降，特别是在有硫氧化物酸雨污染地区的耐蚀性下降较为明显。铝材正面普遍发黑，为黑色密布白点或灰白密布黑点。在海洋大气中，CL—对钝化膜有很强的破坏作用。现有铝扣板的防腐能力较差，无法满足现有需求。
【发明内容】
本发明的目的就是解决现有技术中的问题，提出一种室内用防腐性天花铝扣板制作工艺，能够在铝扣板表面喷塑，将铝扣板与空气之间隔离，有效提高铝扣板的防腐性能。
为实现上述目的，本发明提出了一种室内用防腐性天花铝扣板制作工艺，以下步骤：
步骤S1铝扣板初成型：将未进行过喷涂处理的胚料原料铝板进行冲压和折弯。制得原始面板；
步骤S2酸蚀脱脂：将步骤S1制得的原始面板置于酸蚀脱脂液中进行酸蚀脱脂处理，处理时间为5min-7min浸渍处理，1min-3min喷淋处理；
步骤S3两次水洗：将步骤S2酸蚀脱脂处理后的铝扣板进行先后两次水洗处理，将铝扣板表面的酸蚀脱脂等杂质去除；
步骤S4铬酸盐转化处理：将步骤S3水洗后的铝扣板置于铬酸盐转化液中进行铬酸盐转化处理，处理时间为4min-6min；
步骤S5再次两次水洗：将步骤S4铬酸盐转化处理后的铝扣板进行先后两次水洗处理，将铝扣板表面的铬酸盐转化液等杂质去除；
步骤S6纯水洗：将步骤S5水洗后的铝扣板通过纯水再次进行清洗，控制杂质离子的带入量；
步骤S7沥水烘干：将步骤S6纯水清洗后的铝扣板置于沥水设备上沥去铝扣板表面一部分水分，然后通过烘干设备对铝扣板表面进行烘干处理；
步骤S8铝扣板表面喷塑：将铝扣板置于静电喷塑设备内，利用静电吸附原理，在工件的表面均匀的喷上一层塑料粉末涂料；
步骤S9固化：将步骤S8喷涂完毕后的铝扣板放入烘箱进行烘烤固化，采用170℃-190℃烘烤固化15～25min，实现涂层的充分固化；
步骤S10打包储存：将固化后的铝扣板进行打包装箱后储存备用。
