| 摘要: |
| 盐石膏表面附着有氯盐。氯盐能否与硫酸钙发生共晶,这是长期 以来存在的一个问题。为解决盐石膏的淡化问题,我们研究出一种简单、有效的去氯法,将含氯的盐石膏转化成建筑石膏,进而生产出了石膏板。经省级鉴定,产品 质量达国家部颁一级标准,为新型建材的开发和利用找到了一条新的途径。 |

| A STUDY OF TRANSFERENCE OF SALT-GYPSUM TO CONSTRUCTION-GYPSUM AND ITS PLATE |
|
|
| Abstract: |
| Chlorine salts can be adsorbed on the salt-gypsum and influence its desalination, because chlorine salts may be co-crystalized with CaSO4. A simple and effective method is presented for de-chlorination and transference of salt-gypsum to construction-gypsum and its plate. The quality of resultant products is of the first class according to the national standard. |
