Method for producing small calcium oxide crucible by grouting method
The invention provides a method for producing a small calcium oxide crucible by a grouting method, comprising the following steps of: preparation of raw materials, additives and a binding agent, namely using lime as a raw material, adding the additives and the binding agent into lime; slurry preparation and grouting: adding a certain proportion of water to prepare slurry, fully and uniformly stirring, pouring the slurry into a gypsum mold prepared in advance, and pouring out redundant slurry after a certain thickness is formed; demolding and trimming: demolding the green body when the green body reaches a certain strength in the plaster mold, airing and trimming; drying and calcining: demoulding when the green body reaches a certain strength, airing, fettling and calcining, properly controlling the heating speed in the medium and low temperature sections, and ensuring that the calcining temperature and the heat preservation time are longer than those of an isostatic pressing crucible.The calcium oxide crucible produced by the grouting method does not generate large dust due to wet operation, so that the calcium oxide crucible is more environment-friendly, and what needs to be noted is that heat is released and boiling is generated to prevent scalding in the slurry preparation process.
本发明提供了一种注浆法生产小型氧化钙坩埚的方法，包括：原料、添加剂及结合剂：采用石灰作为原料，加入添加剂及结合剂；制备泥浆、注浆：再加入一定比例的水制成泥浆并充分搅拌均匀，将泥浆倒入事先准备好的石膏模内，待其形成一定的厚度倒出多余的泥浆；出模、修整：待坯体在石膏模内达到一定强度时，将坯体脱模晾干进行修整；干燥、煅烧：坯体达到一定强度时脱模晾干修坯后煅烧，中低温段需要适当控制升温速度，煅烧温度及保温时间要比等静压坩埚高些长些。注浆法生产氧化钙坩埚由于是湿法作业不会产生大的粉尘，更加环保一些，需要注意的是泥浆制备过程中会释放热量和产生沸腾防止烫伤。
