Abstract

The invention provides a binder for forming a net-structured film. The binder comprises the following components in percentage by weight: 15%-65% of synthetic polymer emulsion, 25%-50% of silicate mixture and 5%-10% of water-soluble polymer and a solvent. According to the invention, the binder can form a film with uniform thickness on the surface of evenly mixed ore; the film has a certain strength, thereby preventing an evenly mixed ore groove and a side slope from collapsing and maintaining the original state of the evenly mixed ore not to be damaged under the water flow impact of tap water; the film does not craze under the insolation of sunlight; the extremely fine particles on the surface of the evenly mixed ore can be effectively bound together; and the strength of the film is appropriate, the original state of the film can be restored under the gravity impact of 50cm height, and the film can meet the requirement of a sintering production process.

Description

Technical field [0001] The invention relates to the field of ore pile treatment, and in particular to a binder capable of forming a solid network structure film on the surface of the ore pile. Background technique [0002] During heavy rain and typhoon seasons, the proportion of the upper part of the mine pile is increased due to the infiltration of a large amount of rainwater in the mixing yard of the iron and steel enterprise. At the same time, long-term rain washing will form countless grooves on the surface of the mine pile. In addition, because rainwater accumulates at the bottom of the mine pile, the fluidity of the material increases, and the forces on the trench and the slope are unbalanced. The mine pile often occurs slope and trench collapse events. The consequence of the collapse event is that the rails of the reclaimer on both sides of the yard are often buried by the mixing ore, which has a serious impact on the walking of the reclaimer and seriously affects the sint...
