Preparation method of standard gypsum and application of standard gypsum in detection admixture
The invention belongs to the technical field of gypsum modification, and particularly relates to a preparation method of standard gypsum and application of the standard gypsum in a detection admixture. A modifier is prepared from ethylenediamine tetraacetic acid and silicic anhydride, and surface modification treatment is carried out on natural gypsum, so that the content of semi-aqueous phase gypsum (HH) is greater than or equal to 75%, the content of diaqueous phase gypsum (DH) is less than 3%, and the content of soluble anhydrous phase gypsum (AIII) is less than 3%. And the prepared gypsum can be used as reference gypsum, and the performance of the gypsum admixture can be tested and evaluated.
本发明属于石膏改性技术领域，具体涉及一种基准石膏的制备方法及其在检测外加剂中的应用；采用乙二胺四乙酸和硅酸酐制成一种改性剂，对天然石膏进行表面改性处理，使其物相构成为：半水相石膏(HH)含量≥75％，二水相石膏(DH)含量＜3％，可溶性无水相石膏(AⅢ)含量＜3％。且制备得到的石膏可作为基准石膏，对石膏外加剂的性能进行测试评价。
