Preparation method and equipment of high-temperature-resistant, wear-resistant and strong-impact-resistant anti-corrosion microcrystalline glaze

Abstract

The invention relates to a preparation method and equipment of a high-temperature-resistant, wear-resistant and strong-impact-resistant anti-corrosion microcrystalline glaze. The preparation method comprises the following specific steps: firstly, melting a cover glaze and a ground glaze, respectively crushing cover glaze and ground glaze frits (pieces), adding into a ball mill, adding a grinding additive in a specified proportion into the ball mill, and ball-milling; and after grinding is performed into powder with specified fineness by the ball mill, feeding the powder into a packaging machine through a vacuum conveying system, packaging, feeding into an automatic enamel spraying process after surface glaze powder and ground glaze powder are packaged, and feeding into an enamel firing process after glaze enamel spraying is completed, thereby finally obtaining the anti-corrosion microcrystalline glaze. The prepared glaze has the advantages of ultrahigh mechanical shock resistance, excellent thermal stress resistance, excellent temperature difference sudden change resistance, excellent wear resistance, excellent acid corrosion resistance and excellent alkali corrosion resistance, and is suitable for glass lining equipment and stirring accessories with high reaction medium temperature or solid-liquid mixed solid particle wear as a reaction medium. And subsequent automatic vacuum conveying of the enamel glaze can be realized after ball milling equipment, so that the production efficiency is improved, and the labor consumption is reduced.

Description

technical field [0001] The invention relates to a preparation method and equipment for an anti-corrosion microcrystalline glaze with high temperature resistance, wear resistance and strong impact resistance. Background technique [0002] Silicate system glass-lined glaze, the main skeleton is made of SiO 2 Composition, the internal structure of this kind of glass-lined glaze is composed of silicon-oxygen tetrahedron [SiO 4 】The solid skeleton formed by mutual connection is relatively complete. Generally speaking, a real crystal has a complete and regular appearance and a complete and regular internal arrangement. Crystalline substances generally have a melting point, but there is no uniform arrangement of particles in the amorphous body, and the temperature required to destroy the structure of each part is different. , therefore, there is no definite melting point, which is an important feature that distinguishes it from crystalline objects. [0003] Glass-lined glaze is ...

Problems solved by technology

Subsequent processes such as screening, iron removal, weighing, shaping, coding, stacking, and winding are required. During these processes, the enamel glaze needs to be transferred to multiple stations before subsequent operations can be carried out. In the past, the transportation and transshipment were all done manually, which was very inefficient and labor-intensive. At the same time, because the production of each process could not be carried out quickly, the production efficiency was affected, and the enamel glaze powder was transported to the packaging machine. The powder is easily contaminated with dust, which affects the quality of the powder
