日本INAX公司一改传统的将砖坯放在窑内高温火烧的制砖方法,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,既不会改变粘土颜色,又不会破坏掺入的玻璃片和碎贝壳等, Japan’s INAX Corporation has changed the traditional method of brick brick laying in the kiln at high temperatures and fired the brick blank by high pressure to make a high-strength pressure-hardened brick. This type of brick incorporates glass flakes and crushed shells in clay and uses a high-pressure new process to harden the clay, which will neither change the color of the clay nor damage the incorporated glass flakes and shells.
