Ceramic mold gypsum powder prepared from ardealite-based alpha-type high-strength gypsum
The invention discloses ceramic mold gypsum powder prepared from ardealite-based alpha-type high-strength gypsum. The ceramic mold gypsum powder is mainly prepared from the following components: 1000 parts of ardealite-based alpha-type high-strength gypsum, 0.1-0.8 part of a retarder, 0.1-1.0 part of a thickening agent, 0.1-0.3 part of an air entraining agent and 0.2-0.5 part of a defoaming agent. According to the invention, by adjusting the type and the dosage of the additive, the standard consistency water consumption, the breaking strength and the water absorption index of the gypsum powder for the ceramic mold are accurately regulated and controlled; the ceramic mold gypsum powder meeting four specification grade indexes of first-grade products and qualified products of alpha-type semi-hydrated gypsum and beta-semi-hydrated gypsum in the industrial standard QB/T 1639-2014 Gypsum Powder for Ceramic Mold can be respectively prepared, so that the product indexes can be regulated and controlled according to use requirements, and the ceramic mold gypsum powder has the advantages of cheap and easily available raw materials, simple preparation process and wide application range.
本发明公开了一种磷石膏基α型高强石膏制备的陶瓷模具石膏粉，其主要由以下成分组成：磷石膏基α型高强石膏1000份，缓凝剂0.1～0.8份，增稠剂0.1～1.0份，引气剂0.1～0.3份，消泡剂0.2～0.5份。本发明通过对外加剂种类及用量的调节，实现对陶瓷模具石膏粉标准稠度用水量、抗折强度以及吸水率指标的精准调控，分别能够制备出满足行业标准QB/T 1639‑2014《陶瓷模用石膏粉》中α‑型半水石膏与β‑半水石膏的一级品、合格品四种规格等级指标的陶瓷模具石膏粉，从而实现根据使用需要调控产品指标，具有原料廉价易得、制备工序简单、适用范围广泛的优势。
