Manufacturing method of burner brick for singeing machine

Abstract

The invention provides a manufacturing method of a burner brick for a singeing machine. The method comprises the following steps of (1) putting silicon carbide particles with the particle diameter range being 160 to 325 micrometers into mixed sol prepared into silicon dioxide and aluminum oxide; performing coating treatment; (2) mixing aluminum titanate micro powder and aluminum oxide micro powderaccording to the weight ratio of 1:8-1:14 to obtain mixed powder; adding the mixed powder into 5 to 8 weight percent of PVA glue water and 2 to 5 weight percent of mixed sol; performing material mixing granulation; (3) uniformly mixing the materials obtained in the step (2) and the step (1) according to the weight ratio of 1:2.5-1:4.5; performing pressing shaping to obtain a burner brick biscuitblank; (4) sintering the burner brick biscuit blank for 2 to 3 hours at the temperature of 1500 to 1550 DEG C for 3 hours to obtain a final product. The burner brick for the singeing machine has the advantages that the high-temperature-resistant performance and the thermal shock resistance performance are excellent; the service life is long and can generally reach 18 to 20 months, and is more than6 times of that of a conventional product.

Description

technical field [0001] The invention relates to a burner brick for a singeing machine, which belongs to the field of refractory materials and is used in the textile printing and dyeing industry to form a fire seam when singeing the surface of cloth. Background technique [0002] In order to make the surface of the fabric smooth and clear, not easy to be contaminated with dust, and to prevent the fiber fluff of the fabric from falling during the process of dyeing and printing to cause defects, except for some special varieties, general cotton, linen, and chemical fiber fabrics are dyed before printing and dyeing. All need to go through singeing. [0003] Fabric singeing requires that the hair on the cloth surface be removed as much as possible without causing the fabric itself to catch fire, which requires that the burning of the hair (that is, the oxidation reaction) must be completed in the shortest possible time. Although there are many kinds of singeing machines, gas sin...

Problems solved by technology

Therefore, in actual work, the burner bricks are constantly subjected to high temperature cycles from room temperature to ~1000°C, and are constantly subjected to rapid changes in thermal stress. Under the long-term cyclic thermal stress, the burner bricks are prone to thermal fatigue cracks, and the cracks are prone to lead to burner cracks. Brick Peeling Failure

Therefore, at present, the service life of domestically produced burner bricks in the industry is not long, generally no more than one month, and replacement of burner bricks will not only stop production, but also take time and effort. Higher production efficiency of singeing machine, lower operating costs
