彩色涂層鋼板（彩板）的產(chǎn)生，最早可以追溯到1927年在美國(guó)的涂層薄板生產(chǎn)。但是，真正可以作為第一條具有現(xiàn)代涂層生產(chǎn)線雛形的連續(xù)彩色涂層鋼板生產(chǎn)線是1936年在美國(guó)建立的。至21世紀(jì)初，全世界已經(jīng)有20多個(gè)國(guó)家進(jìn)行彩鋼板的生產(chǎn)，擁有500余條彩板生產(chǎn)線，能生產(chǎn)1000多個(gè)花色品種的產(chǎn)品，有200多種用途，年產(chǎn)量已超過(guò)1500萬(wàn)噸，平均年增長(zhǎng)率達(dá)到10%以上。彩板之所以能得到快速的發(fā)展，除了產(chǎn)品本身具有的優(yōu)良性能之外，還由于生產(chǎn)涂層鋼板帶來(lái)了明顯的社會(huì)效益。彩鋼板是以冷軋鋼板和鍍鋅鋼板等為基板，經(jīng)過(guò)表面預(yù)處理（脫脂、清洗、化學(xué)轉(zhuǎn)化處理），以連續(xù)的方法涂上涂料（輥涂法），經(jīng)過(guò)烘烤和冷卻而制成的產(chǎn)品。涂層鋼板具有輕質(zhì)、美觀和良好的防腐蝕性能，又可直接加工，已經(jīng)在家電行業(yè)得到很大的應(yīng)用和發(fā)展。vcm彩鋼板正面一般選用高分子線性無(wú)油聚酯樹(shù)脂系涂料,添加特殊設(shè)計(jì)的氨基樹(shù)脂及催化劑,以獲得足夠的彎曲性和固化性；并能獲得良好的耐洗滌性,耐污染性及較高的鉛筆硬度.背面采用改性環(huán)氧背漆,一方面能獲得良好的耐腐蝕性,另外也可以獲得優(yōu)異的發(fā)泡附著力。
The production of color-coated steel plates (color plates) dates back to the coated sheet production in the United States in 1927.But the first continuous color-coated steel production line with the prototype of a modern coating production line was established in the United States in 1936.By the beginning of the 21st century, more than 20 countries in the world have conducted color steel plate production, with more than 500 color plate production lines, can produce more than 1,000 varieties of color products, with more than 200 uses, the annual output has exceeded 15 million tons, the average annual growth rate has reached more than 10%.The reason why the color plate can be rapidly developed is that, in addition to the excellent performance of the product itself, but also due to the production of coated steel plate has brought obvious social benefits.Color steel plate is made of cold-rolled steel plate and galvanized steel plate as the substrate, after surface pretreatment (skim, cleaning, chemical transformation treatment), with a continuous method of coating (roll coating method), after baking and cooling products.Coated steel plate has light, beautiful and good corrosion resistance performance, and can be directly processed, has been greatly used and developed in the home appliance industry.The vcm color steel plate front generally adopts polymer linear oil-free polyester resin coating with special design ammonia resin and catalyst to obtain sufficient bending and curing, and good washing resistance, contamination resistance and high pencil hardness. The back has a modified epoxy back paint, which provides good corrosion resistance and excellent foaming adhesion.
