Problems solved by technology

The sintering temperature of the slurry made of this raw material is as high as 1200-1280 degrees. During the sintering process, the energy consumption is relatively large, the loss on ignition rate is high, and the product is easily deformed; in addition, the use of too many hard materials makes the plasticity worse. The strength is reduced, and the product qualification rate is reduced

Embodiment Construction

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] The sanitary ceramic mud of the present invention is mainly composed of the following raw materials in parts by weight: illite clay 30-70, kaolin 5-15, ball clay 6-14, potassium feldspar 8-13, pyrophyllite 5-10, sericite 5 -10, dolomite 0.1-3, water 40-45.

[0021] Among them, the illite-type clay is made of illite-type china clay through weathering, crushing, cone beating, elutriation, sieving, iron removal, decay, and pressure filtration in sequence, and the average weight of the illite-type clay obtained after treatment The particle size is 4.0-5.5um, and particles wi...

Abstract

The invention discloses sanitary ceramics slip and a preparation technology thereof. The sanitary ceramics slip mainly comprises, by weight, 30-70 parts of illite-structure clay, 5-15 parts of kaolin, 6-14 parts of ball clay, 8-13 parts of potassium feldspar, 5-10 parts of pyrophyllite, 5-10 parts of sericite, 0.1-3 parts of dolomite and 40-45 parts of water. Sanitary ceramics prepared from the sanitary ceramics slip are low in firing temperature, little in energy consumption and high in strength, and slip casting qualified rate, semi-finished product qualified rate and firing qualified rate can reach 98%, 96% and 92% respectively.

Description

technical field [0001] The invention relates to the field of sanitary ceramics, in particular to mud for sanitary ceramics and a preparation process thereof. Background technique [0002] The main raw materials of the existing sanitary ceramic mud are potassium feldspar, quartz and kaolin. The sintering temperature of the slurry made of this raw material is as high as 1200-1280 degrees. During the sintering process, the energy consumption is large, the loss on ignition rate is high, and the product is easy to deform when fired; in addition, the use of too many hard materials makes the plasticity worse. The strength is reduced, and the product qualification rate is reduced. Contents of the invention [0003] In order to solve the above problems, the present invention provides a sanitary ceramic slurry with illite-type clay as the main raw material and its preparation process. The sanitary ceramics made from the slurry have low firing temperature, low energy consumption and...
