Frit dry granules with characteristics of one-time sintering and golden brown color, and preparation method thereof

Abstract

The present invention discloses frit dry granules with characteristics of one-time sintering and golden brown color, and a preparation method thereof. Raw materials for preparing the frit dry granules comprise sodium feldspar, lithium porcelain stone, quartz, limestone, dolomite, barium carbonate, non-calcined alumina, raw zinc oxide, fluorite, and a golden brown material. The frit dry granules have characteristics of high melting point, good high temperature flowability, suitable expansion coefficient, wide sintering range, good combination with a ceramic blank, one-time sintering, golden brown color, good gloss, translucent property, shining under light irradiation, and good artistic effect.

Description

technical field [0001] The invention belongs to the technical field of ceramic frit production, in particular to a dry granule of once-fired golden brown frit and a preparation method thereof. Background technique [0002] The natural stone texture is soft, beautiful and elegant, with elegant style. However, large-scale natural stone is extremely scarce and has certain radioactivity. Glass-ceramics is a mixture of microcrystals and glass formed by sintering and crystallizing glass with a certain particle size distribution. The texture is firm and crystal clear. However, glass-ceramic is relatively single in the pattern design process. Antique bricks can make up for this, and thousands of designs can be obtained through micro-powder cloth, screen, roller or inkjet technology to satisfy more consumers. But it does not have the spatial three-dimensionality and crystal clearness of stone and glass-ceramic. The microcrystalline brick is a new type of product that can combine...

Problems solved by technology

However, since the low-temperature glaze firing cycle is generally about 160 minutes, it is several times slower than the high-temperature biscuit firing time (50-70 minutes) of the first firing, which will cause a lot of inconvenience in production

Firstly, the cost of firing is higher than that of general one-time firing; in addition, the bricks supplied by the bisque firing line are larger than the demand of the glaze firing line, and the excess bricks need to be removed manually, and then moved back to the glaze firing line, which not only increases The labor load of employees also takes up storage space in the warehouse, which increases management costs; more importantly, the biscuit firing line cannot be empty during idle time, which will prompt the bisque firing line to frequently switch to other products, and increase the cost of production at the same time. The labor load of the employees, and caused the instability of the kiln, thereby reducing the qualified rate of products
