中文摘要 |
铬盐在生产过程中排出大量有毒废渣,对环境造成严重污染。以铬渣为主要原料,经熔制、成型、热处理和磨光等工序制成微晶玻璃建筑装饰板。铬渣掺量达50%,产品可溶性铬残留量小于0.25mg/kg,物理化学性能指标优于天然花岗石和天然大理石。本法除毒彻底,吃渣量大,拟建成的生产线每年可处理8000t铬渣,经济效益好,是铬渣治理的一条有效新途径。 |
英文摘要 |
The toxic slags which are discharged in a large amount from the production processes of chromates and can cause a serious environmental Pollution were used as a stuning material, through the process stages of smelting, shaping, heat treatment and polishing, to manufacture microcrystal vitreous ceramics as decorative building panels. The slags had a proportion of up to 50% in the compositions of raw materials and less than 0.25 mg/kg of leachable chromium were found in the products which were better in physical and chemical properties than natural granite and natural marble. With this newly developed process having a thorough detoxification and larger consumption of toxic slags, it is planning to construct a production line with a capacity of consuming 8000 t/a of chromic slags. |
