AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a dust covering inhibitor, which mainly solves the technical problems that the existing dust and dust pollution treatment methods are mainly watering, spraying and covering, the cost is high, the maintenance time is short, and the treatment effect is not obvious. , has the characteristics of simple and easy operation, good dust suppression effect, etc. This kind of dust inhibitor not only avoids the waste of water resources, but also reduces secondary pollution, can effectively improve air quality, and achieve the purpose of optimizing the environment

Embodiment 1

[0029] It is compounded with polyacrylic resin as the base material and other effective additives, and its weight percentage is: polyacrylic resin 30%-40%; polyvinyl alcohol 20%-30%; tetraethyl silicate 10%-20% ; Fast penetrating agent 10‰~20‰; OP-1010‰~20‰; Additive 10‰~20‰, the balance is solvent.

Embodiment 2

[0031] It is compounded with polyacrylic resin as the base material and other effective additives, and its weight percentage is: polyacrylic resin 45% to 50%; polyvinyl alcohol 10% to 15%; tetraethyl silicate 10% to 15% ; Fast penetrating agent 5‰~10‰; OP-105‰~10‰; Additive 10‰~20‰, the balance is solvent.

Embodiment 3

[0033] It is compounded with polyacrylic resin as the base material and other effective additives, and its weight percentage is: polyacrylic resin 10% to 20%; polyvinyl alcohol 5% to 10%; tetraethyl orthosilicate 5% to 15% ; Fast penetrating agent 1‰~5‰; OP-101‰~5‰; Additive 10‰~20‰, the balance is solvent.

[0034] After several experiments, we put forward the above three sets of analysis data and conducted experiments in the laboratory. After comparison, the test results of Example 3 are the most ideal: the formed film is uniform and thick, and can maintain the original state without damage under the washing of tap water. Under the sun without cracks.

Abstract

A dust-covered inhibitor consists of polyacrylic acid resin 10-50wt%, polyvinyl alcohol 5-30wt%, ethyl orthosilicate 5%-20wt%, rapid penetrating agent 1%.-20%.wt, OP 100%.-20wt%., additive 10%.-20wt%. and solvent residue. It is cheap, saves resources, has no secondary environmental pollution and improves air quality.

Description

Technical field: [0001] The invention belongs to the technical field of environmental pollution control, in particular to a dust covering inhibitor, which is used in large-scale material storage yards such as: power plant fly ash storage yards, small particle materials, ball powder, coal transportation, sand piles, Sand sculpture, etc., can effectively suppress the generation of dust and the loss of materials. Background technique: [0002] With the development of modern industry, various coal storage yards, ore and other bulk materials stacked in the open air are often full of dust when they encounter weather above the second-level wind during stacking or operation, causing serious pollution to the surrounding atmospheric environment. . At present, many cities in my country have put forward strict requirements to solve the problem of dust pollution of bulk materials such as coal piles and ash piles. Most of these materials are stacked in the open air, and the stacking vol...
