Preparation and application method of fine-mesh dust suppression net for constructional engineering

Abstract

The invention provides a fine-mesh dust suppression net for constructional engineering. The fine-mesh dust suppression net is composed of a fine-mesh net and a dust suppression film, and the dust suppression film is formed by a dust suppressant sprayed to the fine-mesh net. The density of the fine-mesh net is not less than 2000 meshes / 100cm<2>, the dust suppressant is prepared from the following components including, by mass, 0.70-1.0% of sodium alginate, 7.0-8.0% of anhydrous calcium chloride and 0.10-0.20% of cellulose, and the mass ratios of the sodium alginate, the anhydrous calcium chloride and the cellulose are 60 parts, 10 parts and 30 parts. According to the fine-mesh dust suppression net for constructional engineering, the synergistic effect of the dust suppression net and the dust suppressant is fully utilized to obtain a remarkable dust suppression effect, and the selected fine-mesh net can reduce dust flying during construction; the dust suppressant is sprayed to the fine-mesh net to form a dust suppression film, so that the fine-mesh net becomes a good framework of a film structure, and the durability and the dust suppression effect of the dust suppression film are effectively improved; and the dust suppression efficiency of the dust suppression net is improved and the service life of the dust suppression net is prolonged due to good adsorbability and wind erosionresistance of the dust suppression film, and high practicability is achieved.

Description

technical field [0001] The invention belongs to the field of building materials and engineering management, and in particular relates to a method for preparing and applying a fine-mesh dust-suppressing net for construction engineering. [0002] technical background [0003] With the rapid development of urban construction, the dust pollution generated by construction has seriously affected the quality of residents' living environment. Effective control of construction dust pollution is an important part of improving air quality. important research topics. Dust control measures are divided into two forms: one is preventive measures, that is, changing the mode of production activities, and controlling the generation of dust from the front; the other is mitigation measures, that is, taking engineering measures to reduce the intensity of dust emissions. The common dust suppression method in China is the more traditional sprinkler dust suppression method, but this method requires...

Problems solved by technology

[0007] Aiming at the problems existing in the prior art that the dust suppression net is easy to accumulate dust, the dust suppression efficiency is low, and the durability of the dust suppressant is poor, the present invention provides a dense mesh dust suppression net for construction engineering, which can be formed by spraying the dust suppression agent on the dense mesh net. The dust-suppressing film, the dense mesh becomes a good skeleton of the film structure, which will effectively improve the durability of the dust-suppressing film; the dust-suppressing agent has good adsorption, can absorb suspended particles in the air, and has good wind erosion resistance, which can Improve the dust suppression efficiency and service life of the dust suppression net
