Abstract

The invention provides a preparation method for a biological macromolecular dust suppressant. The preparation method comprises the following steps of (1) preparing dextransucrase liquid: preparing an activation culture medium, preparing a mildew production culture medium, activating germs, fermenting the germs, generating an enzyme and separating and purifying the enzyme; (2) preparing a first-stage initial product of the green biological macromolecular dust suppressant: preparing a sucrose solution, performing synthetic reaction and the like; (3) preparing a final product of the green biological macromolecular dust suppressant: mixing the obtained first-stage initial product with an oligosaccharide solution, and mixing a second-stage initial product with wax emulsion to finally form the final product of the biological macromolecular dust suppressant. The dust suppressant prepared by the preparation method disclosed by the invention has the characteristics of high solubleness, proper viscosity, high permeation property, low cost, stable performance, safety to use, greenness, environment friendliness and biodegradation.

Description

technical field [0001] The invention relates to the technical field of environmental pollution control, in particular to a dust suppressant, especially a preparation method of a novel green biological polymer dust suppressant. Background technique [0002] During the conveying and processing process, the powder particles are subjected to the induced air flow, the flowing air caused by indoor ventilation, and the air flow generated by the rotation of the moving parts of the equipment, which will spread and form dust. There are three main causes of dust: [0003] 1. The dust source is dry and easy to oxidize, and the surface particles become smaller to form a powder; [0004] 2. In a naked or naturally weathered state; [0005] 3. There is no wind-proof blocking device outside, which is affected by the wind. [0006] The particle size of dust particles is small, and they are easy to fly. Once they are subjected to external force, they can enter the air again. Therefore, dus...
