Sintering method of glass brick

Abstract

The invention discloses a sintering method of glass brick. The sintering method comprises following steps: firstly, a whole piece of a glass raw material is cut into a glass main body, the glass mainbody is combined with a pigment layer, the pigment layer is coated with a white bottom layer, two times of sintering is carried out in a kiln at 600 to 830 DEG C, wherein in the process of high temperature sintering, the front surface of the glass main body provided with the white bottom layer is placed to be upward for a first time of sintering at 580 to 750 DEG C, and the front surface is placedto be downward for a second time of sintering at 770 to 850 DEG C. The advantages of the sintering method are that: 1, after two times of sintering, breaking or damage of the four corners of the glass brick is not caused, and the color is beautiful; 2, defective rate is reduced greatly, raw material loss is reduced, cost is reduced, and enterprise competition advantages are improved; and 3, afterhigh temperature sintering, fading of the color of the hot molten brick is avoided forever, and the stability is high.

Description

technical field [0001] The present invention relates to a kind of construction material, mainly relates to a kind of hot-melt glass, especially a kind of firing method of the glass block whose four corners can not be damaged. Background technique [0002] At present, the common glass bricks on the market can be roughly divided into low-temperature and hot-melt production methods. The glass bricks produced by the low-temperature method are rich in color, bright and varied in style, but the stability is extremely poor. In the process of use, Once affected by acid and alkali, humidity, sunlight, etc., it is easy to have obvious defects, such as cracks, fading, damage, etc.; and the glass bricks produced by the hot-melt method are stable due to high-temperature treatment (770-850 degrees). However, due to the high temperature treatment, the four corners of the glass bricks are prone to cracks and damages during the high temperature firing process, which will lead to a high defec...

Problems solved by technology

[0002] At present, the common glass bricks on the market can be roughly divided into low-temperature and hot-melt production methods. The glass bricks produced by the low-temperature method are rich in color, bright and varied in style, but the stability is extremely poor. In the process of use, Once affected by acid and alkali, humidity, sunlight, etc., it is easy to have obvious defects, such as cracks, fading, damage, etc.; and the glass bricks produced by the hot-melt method are stable due to high-temperature treatment (770-850 degrees). However, due to the high temperature treatment, the four corners of the glass bricks are prone to cracks and damages during the high temperature firing process, which will lead to a high defect rate of the glass bricks and seriously increase the quality of the glass bricks. Manufacturing costs also increase the difficulty of operation for operators; with the continuous strengthening of enterprise competition, especially the rising labor costs and raw material costs at home and abroad, the firing methods of such glass bricks are becoming less and less competitive
