Colorizing method of building decoration microcrystalline glass produced by sintering method

Abstract

The invention provides a colorizing method of building decoration microcrystalline glass produced by a sintering method. The colorizing method comprises the steps of: preparing glass basic composition materials, adding the glass basic composition materials to a horseshoe flame glass melting furnace for melting, and controlling melting temperature at 1520-1570 DEG C and the temperature of the melting furnace working part at 1360-1420 DEG C; uniformly adding a colorizing agent or an inorganic high-temperature pigment to the molten glass at the front end of the working part through a feeding port at the front end of the working part, arranging a stirring device at the middle of the working part behind the feeding port of the melting furnace, and forming uniform colored glass melt under the combined action of the temperature, molten glass flow and the stirring device; introducing the colored glass melt into a water quenching tank through a supplying channel connected with the working part of the horseshoe flame glass melting furnace, so as to obtain color-uniform glass granules with granularity of 1-6 mm; and carrying out subsequent processing according to a microcrystalline glass preparation process by the sintering method to obtain the product. The prepared glass granules have uniform color, and effectively avoid the problems of color transition material, energy consumption and the like generated by changing glass materials of different colors.

Description

technical field [0001] The invention relates to a method for coloring architectural decorative glass-ceramics by a sintering method, which is particularly suitable for the preparation of multi-variety and small-batch glass-ceramic decorative plates with color requirements. Background technique [0002] As an independent system composite material, glass-ceramics has different technological and structural characteristics from conventional glass and ceramics. It is a polycrystalline solid material containing a large number of crystals prepared by controlled crystallization during heating. As a new type of building decoration material, sintered glass-ceramic decorative plate has been more and more favored by glass workers and architectural designers. Compared with natural stone, sintered glass-ceramic decorative plate has the following advantages: dense structure, high strength, wear resistance, corrosion resistance, clear texture, bright color, no color difference, no fading, ...

Problems solved by technology

Although this process solves the problem of chromatic aberration caused by the change of the valence state of the variable valence metal ion due to melting, it still has the following major disadvantages: the preparation quality of the toner is high, otherwise it will affect the color of the crystallized glass-ceramic plate, such as Defects such as uneven coloring; because the glass frit particles are wrapped by very fine toner, during firing and crystallization, pores and pits are often generated due to uneven melting

[0012] 3. Although the secondary remelting and coloring process overcomes the problems of the above two processes, the glass pellets are heated twice, and the heating temperature is as high as 1200°C-1350°C. Therefore, there will be a lot of energy consumption and increase cost of production

[0013] 4. The coloring process of the feeder channel. Although this method has the characteristics of high production efficiency and reduced production cost, because the distance between the feeder channel and the outlet point is too short, and the temperature at the feeder channel is low, there are Problems such as uneven coloring of glass and limited types of colorants
