Embodiment Construction

[0012] The present invention will be further described below with a specific embodiment:

[0013] refer to figure 1 , a plasticizing process for bone china mud, including hard raw material crushing → batching → grinding → sieving to remove iron → press filtration → stale → vacuum mud refining and other processes. In this embodiment, the raw materials include quartz, For hard raw materials such as ceramic chips, the hard raw materials such as quartz and ceramic chips are crushed in advance until the maximum particle size of the material is <42μm, and these pulverized hard raw materials are mixed with other raw materials according to the formula, and then the mixture is placed in a ball mill. Grind until the maximum particle size of the material is <42μm.

Abstract

The invention relates to a method for improving the pug plasticity in the production process of a bone china. The invention provides a process for plasticizing a bone china pug, which comprises the following process steps: hard raw materials crushing, material blending, grinding, iron removal through sieving, pressure filtration, mustiness, vacuum pugging and the like. The method is characterized in that the raw materials are crushed to grains with the maximum grain size of less than 42 mu m in the process step of crushing the raw materials, and the materials are ground to grains with the maximum grain size of less than 42 mu m in the grinding process step. The method has the following substantive characteristics and marked improvements: 1. the method reveals the corresponding relation between the grain size and the plasticity of the pug, and achieves the aim of improving the plasticity by a method of controlling the fineness of the pug; 2. the production formula of the bone china is designed not to use bentonite or plasticizer at all so as to thoroughly eliminate the negative effects brought by harmful impurities contained in the bentonite and the plasticizer, improves the product quality obviously and reduces the production cost effectively; and 3. the adoption of the process for crushing hard materials such as quartz, ceramic chips and the like in advance can improve grinding efficiency, shorten grinding time, and reduce energy consumption.

Description

Technical field: [0001] The invention relates to a bone china production process, in particular to a method for improving the plasticity of clay. Background technique: [0002] Bone China was first invented by the British in 1807. my country's bone china was first successfully developed in Tangshan, Hebei, and it took 21 years from 1963 to 1984 when it was put into mass production. Due to the introduction of a large proportion of animal bone carbon into the bone china mud, the plasticity of the mud is poor. In order to improve the plasticity of the clay, the scientific research and technical personnel of relevant scientific research units, universities and related enterprises have done a lot of research and experiment work, most of which focus on selecting clay with good plasticity and adjusting the formula design. Therefore, Tangshan is the representative my country's bone china mud generally uses a certain proportion of strong plastic clay - bentonite, and some also use p...
