Embodiment 1

[0020] A quartz micropowder anti-skinning spray coating is composed of the following raw materials in mass percentage: quartz micropowder: 82.95%; α alumina micropowder: 2%; magnesium aluminum spinel fine powder: 2%; pure calcium aluminate cement: 10% %; explosion-proof fiber: 0.05%; binder: 3%; the production steps are as follows:

[0021] (1) Quartz micropowder, α-alumina micropowder and magnesia-aluminum spinel fine powder were evenly mixed for 10 minutes;

[0022] (2) Add explosion-proof fiber and mix for 8 minutes;

[0023] (3) Add pure calcium aluminate cement and mix for 20 minutes;

[0024] (4) add binding agent, mix 8 minutes;

[0025] (5) Inspection and packaging. Ten copies were randomly sampled to test various properties.

Embodiment 2

[0027] A quartz micropowder anti-skinning spray coating is composed of the following raw materials in mass percentage: quartz micropowder: 76.95%; α alumina micropowder: 5%; magnesium aluminum spinel fine powder: 5%; pure calcium aluminate cement: 10% %; Explosion-proof fiber: 0.05%; Binder: 3%; Production steps are basically the same as in Example 1. After completion, randomly sample 10 parts for high temperature performance test.

Embodiment 3

Abstract

The invention provides a quartz micropowder anti-skinning spray coating. The quartz micropowder anti-skinning spray coating is composed of quartz micropowder, alpha aluminium oxide micropowder, magnesium aluminate spinel fine powder, pure calcium aluminate cement, explosion-proof fibre and an adhesive. The invention simultaneously provides a preparation method of the quartz micropowder anti-skinning spray coating. The preparation method comprises the steps of uniformly mixing raw materials and adding auxiliary materials step by step and uniformly mixing. The quartz micropowder anti-skinning spray coating disclosed by the invention can be used for repairing and coating a castable in a rotary kiln conveniently and rapidly when construction conditions are harsh; and furthermore, the quartz micropowder anti-skinning spray coating has good anti-skinning property and thermal shock resistance property.

Description

technical field [0001] The invention relates to the field of refractory materials for cement kilns, in particular to a quartz micropowder anti-skinning spray coating and a preparation method thereof. Background technique [0002] In the cement manufacturing industry, the new dry process cement rotary kiln is widely used. However, with the improvement of cement production efficiency and the increase of output, various impurities in the rotary kiln, including heavy metal ions, sulfur, chlorine, alkali, etc., are cyclically enriched in the rotary kiln, and it is very easy to form a crust in the kiln tail system. Blockage affects the normal operation of the cement rotary kiln. Spray paint is an amorphous lining material constructed by mechanical spraying method using pneumatic tools. It is mainly used for building and repairing furnace lining and coating as a protective layer. However, the existing anti-skinning castables are not light enough, difficult to cast and difficult to...
