岩石平板在国内外日益得到重视,因为它具有下列优点:(1)不会锈蚀;(2)长期自然时效,内应力巳完全消除,不变形;(3)热膨胀系数小,不易热变形;(4)硬度高,约为莫氏5.5—6,耐磨比铸铁强数倍;(5)刚度好,抗弯曲;(6)受划伤后不产生凸纹;(7)隔热性好;(8)维护简单,易于清洁;(9)不易沾微尘(静电荷作用);(10)抗磁、抗油、无闪砾反光等。 Rock slabs are gaining increasing attention at home and abroad because of their advantages as follows: (1) no rusting; (2) long-term natural aging, the internal stress has been completely eliminated and no deformation occurs; (3) the thermal expansion coefficient is small and thermal deformation is not easy; 4) high hardness, about Mohs 5.5-6, abrasion resistance than cast iron several times; (5) good rigidity, bending resistance; (6) scratched by no convex; (7) good heat insulation; (8) easy maintenance, easy to clean; (9) not easy to stick dust (electrostatic charge); (10) anti-magnetic, oil-resistant,
