preparation example Construction

[0020] The invention also provides a preparation method of the foam dust remover, comprising the following steps: firstly add water to the container, heat to 40-50°C, add sodium lauryl sulfate, stir and dissolve; add coconut oil fatty acid diethanolamide, alkanes Glycoside, glycerin and sodium carboxymethylcellulose are stirred, mixed and dissolved to obtain a foam dust remover for construction sites.

[0021] The present invention has no special limitation on the mixing method, and the technical scheme of mechanical stirring or manual stirring well known to those skilled in the art can be adopted, and the purpose is to mix the reaction raw materials evenly.

Embodiment 1

[0024] The foam dust remover is prepared by mixing the following components by weight percentage:

[0025]

[0026] Specifically, add 990.6 g of water to the container, heat it to 50° C., add 1 g of sodium lauryl sulfate for the calculated foam dust removal dose, stir and dissolve; then add 2 g of the calculated foam dust removal dose Coconut oil fatty acid diethanolamide, alkyl glucoside for calculating and preparing foam dust removal dosage 2g, glycerol for calculating and preparing foam dust removal dosage 4g and sodium carboxymethyl cellulose for calculating and preparing foam dust removal dosage 0.4g, stirring, mixing and dissolving to obtain foam dust remover . The obtained foam dedusting agent for the construction site was measured with a Roche foam meter to have a foaming ratio of 172 times. Put it in the foam dedusting device, spray and dedust the mine construction site, and control the spraying amount to 30mL / m 3 , Dust removal is completed after spraying. The ...

Embodiment 2

[0028] The foam dust remover is prepared by mixing the following components by weight percentage:

[0029]

[0030]

[0031] Specifically, add 993.5 g of water to the container, heat it to 50°C, add 2 g of sodium lauryl sulfate, stir and dissolve; then add 1 g of the calculated foam dust removal dose in turn Coconut oil fatty acid diethanolamide, alkyl glycosides with 1g of calculated and prepared foam dust removal dosage, 2g of glycerin with calculated and prepared foam dust removal dosage and 0.5g of sodium carboxymethyl cellulose, mixed and dissolved to obtain construction site foam dust remover. The obtained foam dedusting agent was measured with a Roche foam meter to have a foaming ratio of 158 times. Put it in the foam dedusting device, spray and dedust the mine construction site, and control the spraying amount to 30mL / m 3 , Dust removal is completed after spraying. The CCHG1000 direct-reading dust concentration measuring instrument is used to measure the dust ...

Abstract

The invention belongs to the technical field of construction site dust prevention and discloses a foam dust remover for construction sites. The dust remover mainly consists of 0.1-0.4% coconut oil fatty acid diethanolamide, 0.1-0.2% sodium lauryl sulfate, It is prepared by 0.2% of alkyl glucoside, 0.2-0.6% of glycerin, 0.04-0.06% of sodium carboxymethylcellulose and 98.54-99.46% of water. The synergistic effect of the various components in the foam dust remover for construction sites provided by the invention makes the dust remover have good wettability to dust, rapid dust settlement, good dust removal effect, high foaming multiple, non-toxic and harmless to people and the environment, Does not cause corrosion to electromechanical equipment.

Description

technical field [0001] The invention belongs to the technical field of construction site dust prevention, and in particular relates to a foam dust remover for construction sites and a preparation method thereof. Background technique [0002] Construction sites such as coal mines, tunnel engineering, highways, and subways are all key industries that are subject to dust hazards. In order to improve the working environment in workplaces with high dust concentration, reduce the harm of dust to workers and equipment, avoid dust explosion accidents, and reduce the risk of workers' pneumoconiosis and other hazards, the main methods at home and abroad are dust suppression by spraying, dust removal by dust collectors, and ventilation. Measures such as dust removal and chemical dust suppression, but these measures can only reduce the dust concentration to a certain extent, the effect is not ideal, and the problem of high-concentration dust is still serious. Foam dust removal is a new...
