哈尔滨船舶工程学院粉煤灰开发利用研究室,在研制成功超轻质有机人造大理石后,又研制成一种新型无机人造大理石。这种大理石全部采用无机材料,克服了有机人造大理石表面耐火性不强的弱点,并在表面光洁度、硬度、耐磨质和花纹处理上均优于有机理石,与天然大理石相比可达到鱼目混珠的程度;制造成本低于有机理石1/3或1/5。如制成15毫米厚的其材料费为7—8元/m~2,总成本在10元左右。设备投资5—8千元,一个
After the research and development of fly ash in the Harbin Institute of Shipbuilding Technology, after the successful development of ultra-light organic artificial marble, it was developed into a new type of inorganic artificial marble. All of these marbles are made of inorganic materials, which overcome the weaknesses of the surface of the organic artificial marble that are not strong in fire resistance, and are superior to the mechanism stones in the surface finish, hardness, wear resistance, and pattern processing. Compared with natural marble, they can achieve fish-eye mixing. To the extent that the manufacturing cost is less than 1/3 or 1/5 of the mechanistic stone. If it is made of 15mm thick material costs 7-8 yuan/m~2, the total cost is about 10 yuan. Equipment investment 5-8 thousand yuan, one
