Ceramic pug of large-flow tubular ceramic membrane and preparation method
The invention provides ceramic pug of a large-flow tubular ceramic membrane and a preparation method. The ceramic pug comprises the following raw materials: (1) the solid raw material comprises the following raw materials in percentage by mass: 70-80% of alumina powder with the particle size of 80-120 microns, 10-20% of alumina powder with the particle size of 5-30 microns, 3-7% of a pore formingagent and 5-8% of a sintering aid; (2) the liquid raw material is prepared from the following raw materials in percentage by mass: 15%-25% of a dispersing agent, 10%-15% of a lubricating agent and 60%-75% of pure water, wherein the weight ratio of the solid raw material to the liquid raw material is (3-6): 1. The method is simple in process, proper key process parameters such as mixing, extrusion,drying and sintering are designed, and the percent of pass of the high-flow tubular ceramic membrane is effectively increased; the percent of pass can reach 85% or above, and the production cost is reduced; the product has the advantages of small occupied area and good permeability.
本发明提的一种大流量管式陶瓷膜的陶瓷泥料及制备方法，其陶瓷泥料包括以下原料：（1）固体原料为包括以下质量分数的原料：粒径为80～120μm的氧化铝粉：70%～80%，粒径为5～30μm的氧化铝粉：10%～20%，造孔剂：3%～7%，烧结助剂：5%～8%；（2）液体原料为包括以下质量分数的原料：分散剂：15%～25%，润滑剂：10%～15%，纯水：60%～75%；所述固体原料与所述液体原料的重量比为（3～6）：1。本发明的方法工艺简单，设计合适的混料、挤出、干燥、烧成等关键工艺参数，有效提高大流量管式陶瓷膜的合格率；合格率可达到85%以上，降低了生产成本；产品具有占地面积小、渗透性能好。
