Embodiment Construction
[0016] A waste solidifying agent containing modified nano carbide slag is prepared by mixing the following components in parts by weight (kg):
[0017] Sodium chloride 2, sodium sulfate 2.3, magnesium silicate 0.7, fly ash 0.9, caustic soda 2.6, phosphogypsum 1.5, cement 3.7, chitosan 1.4, alcohol ether glycoside 1.5, 35-40 Baume water glass 0.8, wood Calcium sulfonate 1.3, aluminum oxide 0.8, modified nano carbide slag 2;
[0018] The preparation method of described modified nano carbide slag is:
[0019] (1) Soak the calcium carbide slag with 15% acetic acid solution for 4 hours, wash it with deionized water, then calcinate it at 650° C. for 1 hour, dry it, and pulverize it to obtain the processed carbide slag for subsequent use;
[0020] (2) Dissolve sodium hexametaphosphate equivalent to 3% of the weight of carbide slag in deionized water, then add 2.4% of the weight of carbide slag of alcohol ether glycoside, 1% of diisopropyl phthalate, and 1% of glycerin Triacetate wa...

Abstract
The invention discloses a waste curing agent containing modified nano carbide slag. The waste curing agent is prepared from mixing the following components in parts by weight: 1-2 parts of sodium chloride, 1.5-2.3 parts of sodium sulfate, 0.5-1 part of magnesium silicate, 0.7-1.4 parts of coal ashes, 1.7-2.6 parts of caustic soda, 1.3-1.5 parts of ardealite, 2.5-3.7 parts of cement, 1-2 parts of chitosan, 1-2 parts of alcohol ether glucoside, 0.6-0.8 part of sodium silicate with baume degree of 35-40, 0.8-1.3 parts of calcium lignosulphonate, 0.4-0.8 part of aluminium oxide and 1-2 parts of modified nano carbide slag. In addition to hardening effect of a common curing agent, the waste curing agent containing the modified nano carbide slag further reasonably utilizes the waste and changes the waste into things of value; various materials and the modified nano carbide slag are compounded, so that the hardening effect is strengthened.
Description
technical field [0001] The invention relates to the field of solid waste recycling, in particular to a waste solidifying agent containing modified nano carbide slag. Background technique [0002] If all kinds of slag and other wastes are not effectively treated and utilized, it will be a heavy burden on the development of enterprises, a serious obstacle to social progress, and the greatest harm to the environment and ecology. The effective recycling, recycling, environmental protection and energy saving of various wastes through high-tech science and technology is the greatest contribution to the protection of human survival and long-term social development. [0003] At present, the curing agents commonly used in the urban construction market cannot promote the harmless and effective treatment of various solid wastes, recycle, recycle, and fail to achieve the effects of environmental protection, energy saving, emission reduction, and circular economy. The invention is a hig...
