Problems solved by technology

[0006] The purpose of the present invention is to provide a dense zircon brick and its preparation method to solve the problem that the traditional zircon brick preparation process needs to go through mixing, pressing, firing, crushing, remixing, pressing, and firing processes. It is equivalent to making one kind of brick twice, wasting manpower, natural gas, electricity, etc. The burning of natural gas will inevitably consume energy and cause environmental pollution caused by emissions.

preparation example Construction

[0026] A preparation method of dense zircon brick, comprising the following steps:

[0027] S101, weigh zircon sand, A part of zircon powder, B part of zircon powder, binder and sodium carboxymethyl cellulose by weight respectively;

[0028] S102, firstly adding the zircon sand and the binder into the wheel mixer, and then mixing the zircon sand and the binder evenly;

[0029] S103. Add A part of zircon powder, B part of zircon powder and sodium carboxymethyl cellulose into the cone mixer in turn, and then add A part of zircon powder, B part of zircon powder and carboxymethyl cellulose Sodium mixed well;

[0030] S104, adding the uniformly mixed A part of zircon powder, B part of zircon powder and sodium carboxymethyl cellulose into the wheel mill mixer of step S102, and then mixed for 10-30 minutes to make a semi-dry method mud;

[0031] S105, put the semi-dry mud into the molding silo and trap it for 1-3 hours;

[0032] S106. Use a hydraulic press to press and form, and ...

[0044] The chemical indexes of the test results of the dense zircon bricks prepared in Examples 1-5 are shown in Table 3

[0045] table 3

[0046]

[0047]

[0048] As can be seen from the above table, the dense zircon bricks prepared in Example 4 have the largest bulk density, the smallest porosity, the largest normal temperature compressive strength, and the largest number of thermal shock stability (1100 ° C, water cooling). The physical and chemical indicators of the test results of the dense zircon brick prepared by -5 were compared and analyzed. As the weight ratio of zircon sand increased, the bulk density of the dense zircon brick increased, the porosity decreased, and the pressure resistance at room temperature increased. The strength increases, and the number of thermal shock stability (1100 ° C, water cool...

Abstract

The invention discloses a compact zircon brick which comprises the following components in parts by weight: 50-80 parts of zircon sand, 10-20 parts of zircon powder A, 10-30 parts of zircon powder B, 5-7 parts of a binding agent and 0.1 part of sodium carboxymethyl cellulose, compared with the traditional process, the preparation and granulation process is reduced, the zircon sand, the zircon powder A, the zircon powder B, the binding agent and the sodium carboxymethyl cellulose are directly adopted to prepare the zircon brick, and the production cost is saved; the zircon sand, the zircon powder A and the zircon powder B are adopted as raw materials, so that the finished brick is high in density and low in porosity, and the anti-erosion performance of anti-glass liquid used by customers is high; the semi-dry mixing and extrusion forming semi-finished products are high in strength, the phenomena of corner falling and edge removing caused by low strength of the semi-finished products in the kiln loading process are reduced, the rework rate is reduced, and the benefits of enterprises are improved.

Description

technical field [0001] The invention relates to the technical field of synthesis of refractory materials, in particular to a dense zircon brick and a preparation method thereof. Background technique [0002] Zircon bricks are refractory materials with zirconium silicate (zircon) as the main component; zircon bricks are generally produced by zircon sand, which is formed by grinding zircon sand into micropowder, and then sintered and processed into finished products. However, the existing zircon bricks have the following defects during preparation: [0003] 1. The traditional zircon brick preparation process needs to go through the processes of mixing, pressing, firing, crushing, re-mixing, pressing and firing, which is equivalent to making a brick twice, wasting labor, natural gas, electricity and other natural gas combustion It will inevitably consume energy and cause environmental pollution due to emissions; [0004] 2. The traditional zircon brick preparation process is ...
