Problems solved by technology

However, this material has a high water absorption rate, which will cause later hygroscopic expansion and crack the glazed surface of the product.
At the same time, the strength of this material is smaller than that of VC material, and there are potential safety hazards.

Embodiment Construction

[0026] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0027] Such as figure 1 As shown, according to the raw material components in each embodiment, it is put into the mill, and an appropriate debonding agent and water ball mill are added to obtain the mud. Wherein, the raw material boronite is a kind of calcium borate mineral containing water, which is composed of boron Sodium calcite and borax are formed, and the crystals are short columnar. When directly added to the mud, a certain flocculation phenomenon will occur, which will affect its physical performance. In each embodiment, it is pre-fired at 550°C before use to eliminate Its structure contains water, so it can be used directly, so that the mud can be degummed smoothly, which can ensure the improvement of the firin...

Abstract

The invention relates to the field of preparation processes of sanitary ceramics, in particular to a formula and a preparation method of sanitary ceramics, which improve the refractoriness of a greenbody and reduce the deformation degree of the green body by adjusting the raw material composition of the formula and optimizing the chemical composition. In the mineral composition of a common feldspar porcelain body, a proper amount of wollastonite raw material is introduced, the content of an anorthite crystalline phase is increased on the basis of original mullite and quartz crystalline phases, and a proper amount of closed independent pores are formed, so that the shrinkage rate and the volume density are reduced; by introducing a proper amount of the borocalcite flux, an (O = B-O-B = O)structure can be provided, the integrity and compactness of a network structure around the pores of the borocalcite flux are ensured, and the sizes of the independent pores are controlled within a certain range so as to avoid reduction of the firing strength.

Description

technical field [0001] The invention relates to the field of sanitary ceramic preparation technology, in particular to a sanitary ceramic formula and a preparation method. Background technique [0002] With the steady development of the national economy, people's living standards continue to improve. People's consumption views and aesthetic concepts are also constantly changing. The pursuit of high-quality, high-standard material use is also reflected in the bathroom industry. In the production process of sanitary ceramics, some large-scale products such as toilets and basins (more than 1 meter) are easily deformed and cracked during the firing process. This not only reduces the first-grade rate of the product, but also affects the regularity of the product. At the same time, due to the large size of the product, the weight will be relatively heavy, reaching 20-60Kg. This not only increases the labor intensity of workers during the production and handling process, but al...
