Biodegradable Atmospheric Dust Inhibitors

Abstract

The invention relates to a biodegradable atmospheric dust inhibitor, which is composed of a high molecular polymer extracted and modified from seaweed and auxiliary materials. The auxiliary materials include glycerin, moisturizing agent, accelerator, surfactant and water; By weight percentage, 3-5% of high molecular polymer extracted and modified from seaweed, 1-3% of glycerin, 0.1-1% of moisturizing agent, 0.1-1% of accelerator, 0.1-1% of surfactant, The balance is water. The present invention extracts and further synthesizes the biopolymer material from marine algae, and cooperates with the dust inhibitor prepared by additives. It is environmentally friendly and can reduce the pressure of the marine environment. The product has no secondary pollution and can be biodegraded; the crusting speed Fast, dust control effect is quick; sustainable dust suppression cycle is long, and has the performance of anti-rain, anti-ultraviolet, anti-sun and anti-freeze.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a biodegradable atmospheric dust inhibitor. Background technique [0002] Coal-fired emissions from thermal power and other industries, industrial dust from industries, especially heavy chemical industry, vehicle exhaust, and dust-prone materials are the main sources of atmospheric dust pollution, and the haze we often say is caused by dust particles on the order of microns . The smaller the particle diameter of the dust, the heavy metals it contains and various toxic substances adsorbed will enter the trachea or even the alveoli along the respiratory tract, which is more harmful to health. [0003] Dust also reduces product quality and machine working accuracy. Products such as photosensitive film, integrated circuits, precision instruments and micro motors will reduce their quality or even be scrapped if they are contaminated by dust or their rotating parts are worn or...

Problems solved by technology

When it is used for coal, its specific heat value will be reduced, and the wet material will cause greater wear and tear on the equipment, and it will also cause water pollution, requiring sewage treatment

[0009] 3. Chemical dust suppression agents: the main components are surfactant chemicals and polymers, such as penetrating agents, wetting agents, polymer water-absorbing agents and polymer film-forming agents, etc. These substances usually have certain Pollution, under the action of rainwater, most of the substances such as surfactant penetrants, wetting agents, and polymer monomers that have not been fully polymerized will dissolve in water and enter the ground with rainwater, rivers and seas, and affect groundwater, rivers, etc. Form local pollution with the ocean; when the chlorides of alkali metals or alkaline earth metals dedust coal and mineral stockpiles, they will reduce the combustion value of coal, pollute minerals, and reduce the purity of minerals

However, this kind of dust suppressant mainly uses lignin sulfonate, a by-product of the paper industry, as a raw material. Although the raw material is cheap, it will have a certain color and a strong pungent smell when sprayed on the material, except for special occasions. In addition, it is not suitable for large-scale promotion and spraying
