Problems solved by technology

The quality of the spraying dust suppressant method to control dust largely depends on the performance of the dust suppressant. The existing dust suppressant has the following defects: the film-forming speed of the dust suppressant is slow and the effect is poor; the dust suppressant It is very easy to be damaged by rainwater, and frequent spraying of dust suppressants is required, which leads to an increase in treatment costs; dust suppressants contain a large amount of chemical substances harmful to the environment, and dust suppressants are not easy to degrade, causing secondary pollution to the environment; Dust suppressants can easily lead to soil salinization and compaction, and eventually cause plants in the soil to fail to grow normally

Abstract

The invention discloses an environment-friendly crust type dust suppressant and a preparation method and a use method thereof. The environment-friendly crust type dust suppressant comprises the following raw materials in parts by weight: 20-28 parts of sodium dodecyl sulfate, 10-17 parts of lauramidopropyl betaine, 0.5-1 part of cyclodextrin, 1-3 parts of hyaluronic acid, 1.2-1.6 parts of agar, 3-8 parts of sodium alginate, 1-2 parts of acetic anhydride, 0.4-1.2 parts of a penetrating agent, 0.3-0.8 part of protein powder and 2-7 parts of an emulsifier. The dust suppressant provided by the invention is non-toxic, harmless, non-corrosive and degradable, can rapidly form a hard shell with certain strength on the surface of a bulk pile, has a certain moisturizing effect, can well resist the scouring of rainwater, and further achieves the aim of reducing the treatment cost of dust.

Description

technical field [0001] The invention relates to the technical field of dust suppressants. More specifically, the present invention relates to an environment-friendly encrustation dust suppressant and its preparation method and application method. Background technique [0002] With the progress of the times, the rapid rise of industry and mechanization has also led to the deteriorating domestic environment. Dust in the air is a particularly serious environmental pollution hazard. Dust is one of the main factors leading to environmental pollution. Not only It threatens the safety of production, and is absorbed by the human body in the floating air, directly endangering people's health. Therefore, the control of flying dust is very urgent and necessary to improve the domestic air quality. [0003] At present, the commonly used dust control method is the spray dust suppressant method, which is to form an effective protective layer on the surface of the bulk pile by spraying the...
