Method for preparing potassium dihydrogen phosphate mixed gypsum product surface crystals
The invention discloses a preparation method of potassium dihydrogen phosphate mixed gypsum product surface crystals. The preparation method comprises the following steps: 1, preparing a dissolved slurry of potassium dihydrogen phosphate, gypsum and water; 2, pouring the dissolved slurry into a gypsum product through a mold; 3, demolding and airing; 4, preparing apotassium dihydrogen phosphate aqueous solution; and 5, soaking the air-dried gypsum product mixed with the potassium dihydrogen phosphate into the potassium dihydrogen phosphate aqueous solution prepared in the step 4 to crystallizethe surface of the gypsum product. According to the invention, through the method for separating out crystals on the surface of a gypsum product through a physical and chemical method, the strength and the bending resistance of the gypsum product are improved, the wear resistance and the easy-to-dirty property are improved, and the gypsum product has an ornamental effect.
一种混合了磷酸二氢钾的石膏制品表面结晶的制作方法，包括以下步骤：步骤一、配制磷酸二氢钾、石膏与水的溶浆；步骤二、通过模具将溶浆浇筑成石膏制品；步骤三、脱模晾干；步骤四、配制磷酸二氢钾水溶液；步骤五、将晾干混合了磷酸二氢钾的石膏制品浸泡入步骤四配制的磷酸二氢钾水溶液中使其表面结晶。通过在石膏制品表面上通过物理化学的方法析出结晶的方法，增加了石膏制品的强度及抗折性，提升了耐磨性、易脏性且具有观赏效果。
