Abstract

The invention discloses a preparation method for an engineering ceramic acid and alkali resistant container. The preparation method comprises steps of batching of blank material raw materials, forming of the blank material, batching of glaze material raw materials, preparation of the glaze material, biscuiting, glaze application and sintering. The engineering ceramic acid and alkali resistant container has advantages of high acid resistance, high alkali resistance, particularly being free from pollution of media, high mechanical strength, high compactness, high dimensional precision, low water absorption, good heat stability, small thermal expansion coefficients, leak resistance and the like. The carcass is compact, the glaze is bright and clean, and there are no defects of pin holes, glaze shrinkage, thin glaze and the like. The defective percentage is lowered, and the production efficiency is raised. Temperature-resistant requirements to a kiln device are eliminated, and the production cost is lowered. The novel engineering ceramic acid and alkali resistant container has good appearance quality and performance indexes, and is an ideal product raising economic benefits.

Description

technical field [0001] The invention belongs to the field of ceramic containers, and in particular relates to a preparation process of engineering ceramic acid and alkali resistant containers. Background technique [0002] Acid-resistant and alkali-resistant ceramics are clay semi-ceramic materials with a wide range of applications. They can be used in chemical, smelting, pharmaceutical, food, paper, petroleum and other industrial fields. They have the advantages of corrosion resistance, wear resistance, and no pollution. It is far beyond the reach of other acid and alkali resistant products. Most of the acid-resistant ceramic products widely used in the market are made of kaolin-based clay through wet grinding, beating, concentration, molding, drying, and then high-temperature sintering. The acid and alkali-resistant ceramic products prepared by the method all use natural raw materials, which has high energy consumption, environmental pollution, high carbon emission, high ...
