Preparation method of corrosion-resistant ceramic plaster mold
The invention provides a preparation method of a corrosion-resistant ceramic gypsum mold, which comprises the following steps: uniformly dry-mixing phosphate, cement, an organic admixture and ceramic mold gypsum powder, adding water, stirring, and standing to obtain the ceramic gypsum mold, the adding proportions of the phosphate, the cement and the organic additive are respectively 0.1 to 0.5 weight percent, 0.1 to 1.5 weight percent and 0.3 to 0.5 weight percent. According to the preparation method of the ceramic gypsum mold, provided by the invention, on the premise that the mechanical property and the water absorption property of the gypsum can be maintained, the corrosion effect of an electrolyte solution on the gypsum can be greatly and effectively reduced by adding the phosphate, the cement and the organic additive, the service life of the gypsum is prolonged, the cost is reduced, and the economic benefit is improved.
本发明提供了一种耐溶蚀陶瓷石膏模具的制备方法，所述的制备方法包括：将磷酸盐、水泥、有机外加剂和陶模石膏粉干混均匀，加水搅拌后，静置得到陶瓷石膏模具，以陶模石膏粉的质量为100wt.％计，所述磷酸盐、水泥、有机外加剂的添加比例分别为0.1～0.5wt.％、0.1～1.5wt.％和0.3～0.5wt.％。在本发明中，提供的陶瓷石膏模具的制备方法能维持石膏本身的力学和吸水性能的前提下，磷酸盐、水泥和有机外加剂的添加能大幅有效的降低电解质溶液对石膏的溶蚀作用，延长石膏的使用寿命，降低成本，提高经济效益。
