在建材市场上,瓷砖一直是高档产品,它美观、耐用,易于维修,但装修麻烦,价格昂贵。人们曾用聚苯乙烯塑料制成人造瓷砖,一般规格是4×4英寸。人造瓷砖虽然物美价廉,但仍要一块块拼装,很费工。为此,人们研制了人造瓷砖大板,规格为4×8英尺。最初为低档的,油漆而成的人造瓷砖大板。这种大板由两层硬纸板压制而成,在一层纸板上喷涂上底色颜料,而上层纸板上有肋,模拟砂浆缝,液压机把两层板压紧,压出凹痕,外观好似铺的瓷砖,然后涂上涂料。这种材料耐久性较差,易受潮且易燃,由于涂料主要成分是醇酸,用
In the building materials market, tiles have always been high-end products. It is beautiful, durable, and easy to repair, but it is troublesome to decorate and expensive. People used to make artificial tiles made of polystyrene plastic, the general specification is 4 x 4 inches.

Initially a low-grade, painted artificial tile slab. The board is made of two layers of cardboard. A layer of paperboard is painted with a background pigment. The upper board has ribs. The mortar seam is simulated. The hydraulic press presses the two boards tightly. The dents are pressed. Spread the tiles and apply the paint. This kind of material is poor in durability, it is easy to get wet and flammable, because the main component of the coating is alkyd.
