Embodiment Construction

[0020] The present invention will be described in detail below through examples.

[0021] Take waste ceramics, crush and ball mill, and then sieve to make waste ceramic particles with a fineness of ≤50 μm for later use; by weight of waste ceramics 45%, quartz 8%, feldspar 10%, machine mud 15%, kaolin 22% Percentage Quartz, feldspar, machine mud, kaolin and the above-mentioned spare waste ceramic particles are mixed and put into a ball mill, mixed and ball milled for 30 hours to make mud, and the fineness of the ball mill is controlled to be less than 0.2% after passing through a 325 mesh sieve; After the above mud is screened, iron-removed, press-filtered and mud-smelted, porcelain clay is obtained.

[0022] Use the porcelain clay prepared above to produce decorative art ceramics. The porcelain clay has good plasticity, and the cracking and damage of the body formed by grouting is less than 5%; it is fired in the temperature range of 1230-1250 ° C, the firing condition is good...

Abstract

The invention discloses a method for producing petuntse from waste ceramics, which comprises the following producing steps: taking the waste ceramics, pulverizing and ball milling, and then, sieving to obtain waste ceramic particles for standby, wherein the fineness of each ceramic particle is less than or equal to 50mu m; according to the percentage by weight, taking 7-12% of quartz, 8-13% of feldspar, 15-20% of mechanical pounded pug and 20-30% of kaolin to be uniformly mixed with 40-50% of waste ceramic particles for standby, putting the mixture in a ball mill for mixing and ball milling for 25-35 hours to obtain pug, wherein the ball milling fineness is controlled over 325 meshes, and the sieve residue is less than 0.2%; and sieving, de-ironing, filter-pressing and pugging the pug to obtain the petuntse. In the invention, by controlling the fineness of the petuntse, the plasticity of the petuntse is improved to meet the production requirements, the produced petuntse has good plasticity, the component types needed by producing the petuntse are reduced, various ceramic and porcelanic wastes can be recycled, and compared with the traditional method, the production cost of the method of the invention is greatly saved.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a method for making porcelain clay from waste ceramics. Background technique [0002] my country is a big country producing ceramics in the world, and hundreds of thousands of tons of waste ceramics are produced in production every year. Since waste ceramics have been sintered or fired at high temperatures, they cannot be degraded in natural environmental conditions, and they are discarded in farmland, mountains, roadsides, etc., causing serious pollution to the environment. Prior to this, because the recycling of waste ceramics was only for porcelain waste products, a large number of ceramic waste products were not used, and the technology was not popularized, and the processing cost of waste porcelain was high, resulting in the vast majority of ceramic manufacturers discarding waste ceramics instead of Cause waste of resources and serious environmental pollution. [0003] Due to the a...
