Problems solved by technology

At present, there are many types of surface glazes in production. For example, the porcelain pieces of the prior art have different requirements for the frit in the glazing procedure, and the performance of the glaze is different. The amount of glaze must have a certain thickness, and the temperature and other performance controls Strict, products cannot be mixed firing, production scheduling is li

Example Embodiment

[0020] The weight ratio of the components of the surface glaze of the present invention is: 95% matte frit, 4.3% air knife clay, 0.1% sodium carboxymethyl cellulose, 0.35% industrial sodium tripolyphosphate, 0.25% ceramic degelling agent, and the above 35% water in the raw material ratio. Its preparation method steps are as follows: firstly, prepare the required raw material matte frit, air knife soil, sodium carboxymethyl cellulose, industrial sodium tripolyphosphate, ceramic disintegrant from the market, and the matte frit It is the gold color frit of the Gaoming Jincai Ceramic Chemical Factory in Foshan on the market, the size is in the shape of rice grains; the above-mentioned incoming raw materials are inspected, and after the inspection is qualified, the above-mentioned raw materials and water are stirred and mixed uniformly at room temperature to form a certain stable colloidal dispersion System, the wet ball milling process is performed at room temperature, the ball mil...

Abstract

The invention discloses a cover glaze which is characterized in that: the constituents of the cover glaze are as follows by weight percentage: 90-96 percent of matte fusion cake, 4-6 percent of gas knife soil, 0.08-0.2 percent of sodium carboxymethylcellulose, 0.03-0.36 percent of industrial sodium tripolyphosphate, and 0.20-0.26 percent of ceramic dispergator, and water accounting for 20-26 percent of total proportion of the raw materials. The preparation process flows of the cover glaze are as follows: raw material incoming inspection--batching--ball milling--detection--deironing and sieving--decaying--warehousing and being sieved by 250 meshes of deironing oscillating screen. The ball milling time is 7-10 hours, and ball-milling glazeslip specific gravity is 1.4-1.9g/cm<3>, and the fineness is 0.6-1.0mm; the flowing speed of the ball-milling glazeslip is controlled above 55s. The cover glaze has the advantages of transparent and smooth performance, bright color and luster and wide market prospect.

Description

technical field [0001] The invention relates to the field of ceramic raw materials, and more specifically relates to a formula of a top glaze and a preparation process thereof. Background technique [0002] The rapid growth of social economy has driven the development of the construction industry, and ceramic building materials such as ceramic products are widely used in the market because of their high hardness, good wear resistance, high density, small shrinkage deformation, and good decorative effects. Glaze is a layer of enamel covering the surface or bottom glaze of the product in the manufacturing process of enamel or ceramic products, which can resist corrosion and increase the decorative effect of the product. At present, there are many types of surface glazes in production. For example, the porcelain pieces of the prior art have different requirements for the frit in the glazing procedure, and the performance of the glaze is different. The amount of glaze must have ...
