Abstract

The invention discloses a low-smoke-intensity and high-sulfur fixation adhesion agent. The adhesion agent consists of the following components in parts by weight: 30-40 parts of magnesium oxychloride cement, 10-20 parts of bentonite, 20 parts of steel furnace waste slag, 5 parts of graphite gangue, 2 parts of trisodium phosphate, 8 parts of sodium silicate, 3 parts of a solidification agent, 7 parts of a hardening agent and 5 parts of polyethylene glycol. The low-smoke-intensity and high-sulfur fixation adhesion agent provided by the invention has the advantages of low smoke blackness and good sulfur fixation performance; moreover, combustion performance of briquette coal cannot be changed, no calorific value is not reduced, briquette coal has good waterproofness, cold and hot strength is high and mechanical performance is good.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a binder. Background technique [0002] The gasification industrial briquettes currently produced in China have many defects, such as briquettes are not waterproof, need to be dried, high cost, low heat and cold intensity, poor gasification effect, black heart, poor reducibility, low gasification rate, oxygen High content, low carbon monoxide output, low calorific value of gas. Not suitable for mass production and cannot be transported over long distances. There are many kinds of binders used at home and abroad, such as coal tar, asphalt, papermaking waste liquid, animal blood (blood meal), biochemical sludge, cement, calcium carbide and so on. But these schemes or on the production cost, or on the briquette strength, water resistance, there are deficiencies in varying degrees. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object...
