Embodiment 1

[0029] This embodiment provides a method for processing putty powder using coal gasification ash as the main raw material. The specific process is as follows:

[0030] a. Primary processing of coal gasification ash: Grind the raw material of coal gasification ash to a particle size of 100 μm, mix and stir with polyacrylamide solution at a ratio of 1000:3 to obtain a mixture; add 0.8% of the total weight of the mixture to fatty acid polyethylene glycol Alcohol esters, continue to stir, add an appropriate amount of deionized water, and stir at a stirring speed of 1200r / min to form a slurry S with a consistency of 1.5; before processing the coal gasification ash raw material, it is necessary to control its combustion degree to exceed 99% , the purpose is to improve the purity of coal gasification ash raw material, so that it can be fully burned before processing to form white ash with uniform texture;

[0031] Take 3% lime mud, 7% quicklime, and 2% talcum powder, which account fo...

Embodiment 2

[0041] This embodiment provides a method for processing putty powder using coal gasification ash as the main raw material. The specific process is as follows:

[0042]a. Primary processing of coal gasification ash: Grind the raw material of coal gasification ash to a particle size of 85 μm, mix and stir with polyacrylamide solution at a ratio of 1000:5 to obtain a mixture; add 0.5% of the total weight of the mixture to fatty acid polyethylene glycol Alcohol ester, continue to stir, add appropriate amount of deionized water, and stir at a stirring speed of 1300r / min to form a slurry S with a consistency of 1.4; before processing the coal gasification ash raw material, it is necessary to control its combustion degree to 99.5% , the purpose is to improve the purity of coal gasification ash raw material, so that it can be fully burned before processing to form white ash with uniform texture;

[0043] Take 5% lime mud, 4% quicklime, and 4% talcum powder, which account for the total...

Abstract

The invention relates to the technical field of putty powder processing, and particularly relates to a method for processing coal gasification ash and slag to obtain putty powder. The coal gasification ash and slag, as a main raw material, white clay, quick lime, talc powder, and other raw materials are aged, calcinated and ground into fine coal gasification ash and slag; and then the fine coal gasification ash and slag, titanium dioxide powder, ferric oxide, organic rubber powder, an auxiliary material, talc powder, and other raw materials are mixed to prepare a putty powder finished productwhich is green, thus effectively utilizing the comprehensive utilization efficiency of the coal resource, achieving secondary utilization of the coal gasification ash and slag, turning waste into things of value, and saving the national ore resource of China. In addition, the titanium dioxide powder, the talc powder, the white clay, the ferric oxide, and other materials are added in the putty powder processing process to effectively improve whiteness of the putty powder finished product, and plant essential oil is added to achieve sterilizing and bacteriostatic functions so that the product isgreen and healthy.

Description

technical field [0001] The invention relates to the technical field of putty powder processing, in particular to a method for processing coal gasification ash on putty powder. Background technique [0002] Putty powder is a kind of building decoration material, the main components are talcum powder and glue. I just bought a layer of white putty on the surface of the blank room. Usually the whiteness of the putty is above 90° and the fineness is above 330°. Putty powder is a kind of base material for leveling the wall, which lays a good foundation for future decoration (painting and wallpaper). Putty is divided into two kinds: putty inside wall and putty on exterior wall. External wall putty can resist wind and sun, so it has good gelation, high strength and low environmental index. The comprehensive index of putty in the inner wall is good, and it is hygienic and environmentally friendly. Therefore, the inner wall is not for external use and the outer wall is not for inter...
