防止卫生陶瓷制品产生裂口,是一个很复杂的问题。根据实践经验,从以下几个方面加强管理,提高操作技术,可取得良好的效果。一、原料的加工处理1.粘土原料一般都要风化半年以上,经过多次膨胀与收缩,使之分解成细小颗粒,增加胶体物质,提高可塑性,在成型时可减少坯体开裂。2.在泥料配方中,可塑性原料和非可塑性原料用量要适当。如塑性原料用量过多,影响吃浆速度,容易塌活,在干燥时
Preventing cracks in sanitary ceramic products is a complex issue. According to practical experience, strengthening management and improving operating techniques from the following aspects can achieve good results. First, the processing of raw materials 1. Clay raw materials are generally weathering more than six months, after multiple expansion and contraction, so that it breaks down into small particles, increase the colloidal material, improve plasticity, can reduce the body cracking when molding. 2. In the mud formulation, the amount of plastic raw materials and non-plastic raw materials should be appropriate. If the amount of plastic raw material is too much, it will affect the speed of pulping and it will be easy to collapse when it is dry.
