日本INAX公司一改传统的将砖坯放在窑内高温火烧成形的制砖方法,通过高压使砖坯硬化,制成了高强度压力硬化砖。 这种高强度压力硬化砖,是在粘土中掺入玻璃片和碎贝壳等,采用高压新工艺,使粘土硬化制成,既不会改变粘土颜色,又不会破坏掺入 Japan’s INAX Corporation has changed the traditional method of brick making by placing bricks in a kiln at a high temperature and firing them. The bricks are hardened by high pressure and high-strength pressure-hardened bricks are made. This kind of high-strength pressure-hardening brick is made by adding glass flakes and crushed shells to clay and using high-pressure new technology to make the clay hardened, which will neither change the color of the clay nor damage the incorporation.
