Efficient physical modification method for titanium gypsum
The invention discloses an efficient physical modification method for titanium gypsum. The method comprises the steps of drying the titanium gypsum; and placing the titanium gypsum in a drying box to be dried, and removing free water in the titanium gypsum, wherein the temperature of the drying box is 50-60 DEG C. According to the efficient physical modification method for titanium gypsum, a titanium gypsum homogenization step is added in the preparation step of titanium gypsum physical modification, the titanium gypsum powder is placed in a kiln, the temperature is kept at 160-180 DEG C, titanium gypsum powder is homogenized for 2-3 h, titanium gypsum is homogenized, chemical components of the titanium gypsum tend to be uniform and are diffused and homogenized, titanium gypsum calcination products such as beta-semi-hydrated gypsum, III-type anhydrite and undehydrated dihydrate gypsum are uniformly distributed, so that the texture of the titanium gypsum powder is more uniform, and the thermal stability of titanium gypsum fragments is remarkably enhanced, and meanwhile, the strength of the hardened titanium gypsum is improved.
本发明公开了一种钛石膏高效物理改性的方法，包括以下步骤：钛石膏烘干；将钛石膏放在干燥箱内进行烘干，脱除钛石膏内部的自由水，烘干箱的温度为50℃‑60℃，本发明一种钛石膏高效物理改性的方法通过在钛石膏物理改性的制备步骤中新增了钛石膏均化步骤，通过将钛石膏粉料放置在窑炉内，保持160℃～180℃，对钛石膏粉料进行均化2h‑3h，对钛石膏进行均化处理，其化学成分趋于均一并扩散均化，钛石膏煅烧的产物β半水石膏、III型无水石膏和未脱水的二水石膏分布均匀，从而使得钛石膏粉料质地更加的均匀，显著增强了钛石膏碎屑的热稳定性，同时提高钛石膏的硬化后的强度。
