Problems solved by technology

At present, some chemical dust suppressants existing at home and abroad only bond and solidify the flowing dust, so that the dust will not flow for a period of time. Expensive, toxic and side effects, highly corrosive, difficult to degrade and secondary pollution, etc., and none of them have the function of bactericidal and antiviral

Embodiment 1

[0022] The invention provides an antiviral soil-fixing and dust-suppressing agent, which consists of the following components: 1%-3% of carboxymethyl chitosan, 1%-3% of polyacrylamide, 2%-4% of sodium alginate, ten Dialkyl sodium sulfonate 0.25%-4%, carboxymethyl cellulose 2%-4%, and the balance is water. Concrete, the massfraction of carboxymethyl chitosan is 3%, the massfraction of polyacrylamide is 2%, the massfraction of sodium alginate is 3%, the massfraction of sodium dodecylsulfonate is 2%, The mass fraction of carboxymethyl cellulose is 3%.

[0023] Its principle is:

[0024] (1) Principle of chemical dust suppression

[0025] Dust has adhesion and wettability, so according to this characteristic, the basic theory of using related chemical methods to suppress dust can be obtained: when the dust is in a relatively humid environment, use chemical methods to keep the surface of the dust relatively wet , which has a certain water content, so as to achieve the effect of ...

Embodiment 2

[0083] This example proposes a preparation method of an antiviral soil-fixing and dust-suppressing agent, which includes the following steps: mixing the components in proportion to prepare an aqueous solution, and mixing evenly to obtain the product. Among them, the material of the reaction kettle used to prepare the dust suppressant is stainless steel or plastic, and iron or other metals cannot be used, otherwise it will react with the reaction kettle and affect the dust suppression performance of the dust suppressant.

Embodiment 3

[0085] This embodiment is the application of the antiviral soil-fixing and dust-suppressing agent in dust control, sand prevention and sand-fixing or ecological slope protection. When in use, the dust-suppressing agent is diluted with water and sprayed on the area to be treated. Wherein, the multiple of diluting the dust suppressant is 10-30 times.

[0086] When in use, it can be sprayed manually in a small area, and can be sprayed efficiently in a large area with a sprinkler or other machinery. After spraying, wait for natural drying. After the structure of the consolidated layer is relatively stable, plan a gap in the consolidated layer, observe the appearance of the consolidated shell, and record the thickness of the consolidated layer.

[0087] Application of environment-friendly anti-virus soil-fixing and dust-suppressing agent in dust control of construction waste factory:

[0088] During the crushing process of a construction waste factory, the construction waste was s...

Abstract

The invention discloses an antiviral soil-fixing dust suppressant as well as a preparation method and application thereof. The dust suppressant is prepared from the following components: 1%-3% of carboxymethyl chitosan, 1%-3% of polyacrylamide, 2%-4% of sodium alginate, 0.25%-4% of sodium dodecyl sulfate, 2%-4% of carboxymethyl cellulose and the balance of water. The dust suppressant is a novel dust suppressant which is prepared by taking natural marine organisms as main raw materials and taking three industrial byproducts as auxiliary materials through optimized combination and has the functions of soil fixation, dust suppression and virus resistance, and the dust suppressant is wide in raw material source, capable of being completely degraded, free of secondary pollution to the environment and capable of promoting plant growth. The dust suppressant avoids the defects of the traditional dust suppressant, realizes the real change of wastes into valuables while effectively controlling dust pollution, can be used for sand prevention and stabilization and ecological slope protection, and can effectively control the transmission of bacteria and viruses, thereby having wide applicationprospects.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to an antiviral soil-fixing and dust-suppressing agent and its preparation method and application. Background technique [0002] With the acceleration of urbanization in our country, infrastructure construction is carried out on a large scale. However, due to the rapid development of industry, excessive exploitation of resources, and massive destruction of vegetation, the solid suspended particles in the atmosphere exceed the standard, and the haze weather is frequent, and the problem of air pollution is becoming more and more prominent. Studies have shown that among urban air pollutants, fugitive dust caused by unorganized emissions from roads, bare ground, construction waste plants, slag and its material storage yards accounts for about half of the total solid suspended particles, and maintains a high concentration for a long time. It causes reduced visibility in the su...
