美国市场已出现系列人工合成石板,不仅在耐热、坚固等性质上可与天然的花岗石和大理石媲美,而且外表美观,具有多种颜色、图案。对烧痕、污渍等十分容易清除,价格便宜。主要品种有:杜邦公司推出的 Corjan 板,其制法是首先配成一种丙烯(如异丁烯酸甲酯)、聚酯或丙烯-聚酯树脂浓液,在其中加入一些如氢氧化铝、合金或陶瓷等粉状硬矿物质粒子。所形成的浆倒入模内烘烤成板状,树脂起胶结作用,金属粒则起稳定作用。这种板具有抗膨胀、收缩、扭曲和挠起,耐热及耐撞击性能,且易于切削加工。
In the United States, a series of artificial stone slabs have emerged, which are not only comparable to natural granites and marbles in terms of heat-resistance and sturdiness, but also have a beautiful appearance and a variety of colors and patterns. Burn marks, stains, etc. are very easy to remove and cheap. The main varieties are: Corjan boards introduced by DuPont Co., Ltd., which are prepared by first formulating a kind of propylene (such as methyl methacrylate), polyester or acrylic-polyester resin dope, and adding some of them such as aluminum hydroxide and alloys. Or powdered hard mineral particles such as ceramics. The resulting slurry is poured into molds and baked into plates. The resin acts as a cement and the metal particles act as a stabilizer. This kind of board has resistance to expansion, shrinkage, distortion and deflection, heat resistance and impact resistance, and is easy to cut.
