Embodiment 1

[0043] The composition of the high-strength building construction site rapid film-forming dust suppressant is:

[0044] Sodium alginate solution: the mass concentration of sodium alginate is 0.75%, and the mass concentration of methyl cellulose is 0.10%;

[0045] Calcium chloride solution: the mass concentration of calcium chloride is 7.5%.

[0046] How to use: After preparing sodium alginate solution (containing methyl cellulose) and calcium chloride solution, first spray the sodium alginate solution on the ground surface of the construction site, and then spray the above chlorine on the surface of the same construction site The spray ratio of calcium chloride solution, sodium alginate solution and calcium chloride solution is 1:0.80 by volume.

[0047] For areas where pedestrians and vehicles pass more frequently such as unhardened road surfaces and horse paths, after spraying the dust suppressant of the present invention, the consolidation layer and surface adhesive film a...

Embodiment 2

[0049] The mass concentration of methylcellulose in the sodium alginate solution is 0.05%, and the others are the same as in Example 1.

Embodiment 3

[0051] The mass concentration of methylcellulose in the sodium alginate solution is 0.15%, and the others are the same as in Example 1.

Abstract

The invention discloses a rapid film-forming dust suppressant for a high-intensity building construction site. The rapid film-forming dust suppressant is obtained by adding water-soluble nonionic mono-ether substituted cellulose ether into a dust suppressant taking calcium alginate as a main film-forming component, wherein the calcium alginate is obtained through a reaction between a sodium alginate solution and a calcium chloride solution, and the water-soluble nonionic mono-ether substituted cellulose ether is methylcellulose. After cellulose is added into the dust suppressant, the dust suppressant disclosed by the invention still has good rapid film-forming properties and caking properties, can effectively solidify surface layer fine particles and rapidly form a dense film on the surface to cover the exposed earth surface, the film intensity of the dust suppressant is also greatly improved and can reach 4-5 times that of a dust suppressant without the cellulose, and the dust suppression effect is obviously improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of building materials / engineering management, and more specifically, embodiments of the present invention relate to a high-strength rapid film-forming dust suppressant for construction sites. Background technique [0002] In recent years, my country's cities have developed rapidly, and the impact of construction dust on the atmospheric environment is very prominent every year, seriously affecting the quality of the living environment of urban residents. Common dust suppression measures in construction sites in my country are watering, covering and ground hardening. Sprinkling generally has low dust suppression efficiency, and the effective time lasts only a few hours at most, requiring repeated work, resulting in a large amount of manpower and material resources consumption. When the soil nutrient loss intensifies and the moisture content decreases, the dust pollution will be more serious. Cove...
