Activation molded coal adhesive, preparation method and application thereof

Abstract

The invention discloses an activated coal adhesive and preparing method and application, which comprises the following parts: 20-22% alkaline disposing wood slag, 38-40% sodium phytate, 26-28% swelling soil, 9-10% lime, 1.5-2.5% zeolite and 1.5-2.5% industrial salt.

Description

technical field [0001] The present invention relates to a binder, more specifically relates to an activated briquette binder. Background technique [0002] The current briquette technology is mainly based on binder forming technology, that is, under a certain pressure, the binder acts as a "bridge" between the particles on the surface of the coal particles to make the particles combine and form. Molding at high temperature or normal temperature, low molding pressure (15-50MPa), simple process, easy to control, and low investment, is a molding process commonly used at home and abroad. The adhesives used in this process are generally: organic adhesives, There are three kinds of inorganic binders and composite binders. The composite binder is a combination of the above two or more binders to make up for the lack of a single binder, so that the briquette can achieve better quality and is sticky. The mixture is added in a liquid state, and some binder adding processes also requi...

AI Technical Summary

Problems solved by technology

[0010] 1. Adhesives with excellent performance are expensive, and the cost increases after adding;

[0011] 2. The joining process is complicated, which increases the investment and the cost of briquette production;

[0012] 3. There is a "black heart phenomenon" that cannot be burned through;

[0013] 4. The molding process is complicated, especially the binder adding process is complicated, which makes it difficult to scale industrial production;

[0014] 5. The source of raw materials is narrow, and some also cause secondary pollution

[0015] 6. Some binders are added in a large amount, and the ash content increases greatly
