Enhanced environment-friendly ceramic plaster mold and preparation method thereof
The invention discloses an enhanced environment-friendly ceramic gypsum mold and a preparation method thereof and belongs to the technical field of environment-friendly molds. The preparation method comprises the following steps of: mixing a gypsum mixture and water, pouring an obtained mixture into a container, uniformly stirring and mixing the mixture, injecting the uniformly mixed slurry into amold, taking out a gypsum mold after the slurry is condensed into the gypsum mold, and drying the gypsum mold to obtain the enhanced environment-friendly ceramic gypsum mold. A method for obtaining the gypsum mixture includes the following steps of: uniformly mixing and stirring waste gypsum, desulfurized gypsum and sodium alginate as raw materials under a mechanical action to obtain a mixture; putting the mixture into a dehydrator for dehydration to obtain semi-hydrated gypsum; and drying, cooling and grinding the semi-hydrated gypsum into powder to obtain the gypsum mixture. According to the preparation method, the gypsum mixture is low in porosity and high in fineness, the interaction force among particles is firmer, and therefore, the enhanced environment-friendly ceramic gypsum moldwhich is compact in structure, high in water resistance and corrosion resistance, high in strength and the like and has a series of excellent properties can be obtained.
本发明公开了一种增强型环保陶瓷石膏模具及其制备方法，属于环保模具技术领域，其制备方法包括：将石膏混合料和水混合倒入容器中，搅拌混合均匀，将混合均匀的浆料注入模具中，待浆料凝结成石膏模具，将其取出，干燥，即得到增强型环保陶瓷石膏模具。所用石膏混合料通过如下方法获得：将废旧石膏、脱硫石膏、海藻酸钠作为原料，在机械作用下混合搅拌均匀，得到混合料；将混合料投入到脱水机中脱水，得到半水石膏；将半水石膏干燥，冷却，研磨成粉体，即得到石膏混合料。本发明制备方法用石膏混合料的孔隙率低，细度高，颗粒间的相互作用力更为牢固，可得到结构致密、较强的耐水耐蚀性以及高强度等具有一系列优良性能的增强型环保陶瓷石膏模具。
