Ceramic pug

Abstract

The invention discloses ceramic pug. The ceramic pug is prepared from the following raw material components in parts by weight: 30-40 parts of kaolinite powder, 1-2 parts of nanosilicon dioxide, 2-3 parts of aluminium oxide, 2-5 parts of montmorillonite powder, 10-20 parts of mica powder, 15-20 parts of vermiculite powder, 5-10 parts of ceramsite powder, 3-5 parts of turf, 5-10 parts of zeolite powder, 10-15 parts of pyroxene powder, 10-15 parts of hornblende powder, 2-5 parts of magnesium oxide, 2-3 parts of ferric oxide, 3-5 parts of aluminium hydroxide, 5-8 parts of limestone, 2-3 parts of sodium metaaluminate, 3-5 parts of Na[Al(OH)4] and 5-8 parts of polycarboxylate water reducing agent. The ceramic pug has the advantages that the defects of easy deformation and unstable shrinkage ratio in a firing process are overcome, the shrinkage ratio is controlled under the synergistic effect of all the components in a formula, so that a product has small possibility of deformation in the firing process; meanwhile, firing shrinkage ratio is controlled to be 14-15%, the range of firing temperature of the product can be expanded, so that yield of fired products is high, and the requirement of large-scale industrial production is met.

Description

technical field [0001] The invention relates to the technical field of raw materials for finished products, in particular to a special clay material for finished ceramic products. Background technique [0002] At present, in the manufacturing process of ceramic products, how to control the shrinkage ratio during the firing process of the product has always been a key concern of the industry, and the key to the impact on the shrinkage ratio is the control of the composition of the mud. In some ceramic applications For special occasions, such as ceramic wine bottles, the requirements for shrinkage ratio and firing strength of the body are more stringent. It is well known that the necks of ceramic wine bottles in the prior art are seldom threaded. This is because: the industry has not found a mud formula with relatively stable shrinkage and high firing strength of the body, resulting in the obtained ceramics The mouth of the wine bottle does not match the thread of the bottle ...

Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of ceramic mud in order to overcome the above-mentioned shortcoming of prior art, and this ceramic mud overcomes the shortcoming that is easily deformed in firing process, shrinkage ratio is unstable, and the synergistic play of each component in formula Control the shrinkage ratio under the action, so that the product is not easily deformed when fired. Controlling the firing shrinkage ratio at 14-15% can widen the temperature range of product firing, making the product firing rate higher, and meeting the requirements of large-scale industrial production.
