Reinforcing method for grouting mold
The invention discloses a strengthening method for a grouting mold. The strengthening method comprises the steps of raw material pretreatment, auxiliary material adding, water adding and primary stirring, paste injection, solidification forming, mold taking, curing and drying, coating and the like. According to the invention, polar Na2SiO3 and Na2CO3 electrolyte solutions are isolated from the surface of the gypsum mold through an organic fluorine-modified polyurethane coating with strong hydrophobicity, so that the alkaline electrolyte solution is effectively prevented from wetting the surface of the gypsum mold and corroding the gypsum, and meanwhile, a polypropylene long fiber structure with stretchability is added in the gypsum, so that gypsum particles can be stably attached to the surface of the gypsum mold to form a reinforcing structure. In addition, Portland cement capable of forming a stable hole structure is added into the gypsum slurry to serve as a framework to guarantee smoothness of holes in the gypsum mold. The reinforcing method not only enhances the strength of the gypsum mold, but also effectively improves the water resistance and corrosion resistance of the plaster mold, and remarkably improves the durability of the plaster mold from 70 times to 120 times.
本发明公开了一种用于注浆类模具的强化方法，包括原料前处理、添加辅助料、加水初搅拌、注膏、凝固成型、取模、养护烘干、涂覆涂层等。本发明通过强疏水性的有机氟改性聚氨酯涂层，将极性Na2S iO3、Na2CO3类电解质溶液与石膏模具表面隔离开，有效防止碱性电解质溶液润湿石膏模具表面，溶蚀石膏，同时石膏内部增加具有可拉伸性的聚丙烯长纤维结构，保障石膏颗粒能够稳定依附在石膏模具表面，形成增强结构，此外，在石膏浆体中加入具有可形成较稳定孔洞结构的硅酸盐水泥作为骨架来保障石膏模具内部的孔洞顺畅，该强化方法不仅增强了石膏模具的强度，还有效改善了石膏模具的耐水、耐溶蚀性能，其耐用度由70次显著提高到120次。
