Embodiment 1

[0021] A salt-spray corrosion-resistant porcelain, comprising the following raw material components in parts by weight: 41 parts of clay, 26 parts of modified Dikai stone, 17 parts of modified china clay, 4 parts of sepiolite, and 4 parts of montmorillonite , 4 parts of loess, 4 parts of vermiculite, 8 parts of light calcium carbonate, 3 parts of cobalt silicide powder, 3 parts of zirconium silicide powder, and 3 parts of vanadium boride powder.

[0022] The modified dikai stone is prepared by the following method: adding white vinegar to the dikai stone and then burning it to 260-300°C, then soaking the dikai stone in glutinous rice water, taking out the dikai stone and draining it to maintain the moisture content At 8%-10%, then treat it under the pressure of 4-4.5MPa for 1 hour, take out the Dikai stone and soak it in the soaking solution for 1 hour, remove the Dikai stone and continue to calcine to 340-360°C, and then in 1 minute Allow to cool to room temperature.

Abstract

The invention relates to the field of ceramics, particularly a salt-spray-corrosion-resistant porcelain which contains the following raw materials in parts by weight: 38-44 parts of clay, 24-28 parts of modified dickite, 14-20 parts of modified porcelain clay, 2-6 parts of meerschaum, 2-6 parts of smectite, 2-6 parts of loess, 2-6 parts of vermiculite, 6-10 parts of light calcium carbonate, 2-4 parts of cobalt silicide powder, 2-4 parts of zirconium silicide powder and 2-4 parts of vanadium boride powder. The porcelain can resist the corrosion of salt spray with the concentration of 15-20%, can be continuously used in a salt spray environment for 15 years without changes, can resist the corrosion of strong acid with the concentration of 80%, and has favorable surface abrasion resistance.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a salt-spray corrosion-resistant porcelain and a manufacturing process thereof. Background technique [0002] The utensils fired with clay are called pottery, and the utensils fired with china clay are called porcelain. Porcelain is the general term for pottery, stoneware and porcelain. Any utensils made of two different types of clay, pottery clay and porcelain clay, as raw materials, through batching, molding, drying, roasting and other processes can be called ceramics. [0003] The development history of ceramics is an important part of the history of Chinese civilization. As one of the four ancient civilizations, China has made outstanding contributions to the progress and development of human society. Among them, the invention and development of ceramics has unique significance. Different dynasties and dynasties in Chinese history have different artistic styles and different techni...
