Problems solved by technology

The existence of foam will not only affect the homogeneity and dispersion properties of the mixed solution, but may further affect the properties of spray droplets
[0004] Through the observation of many wet spray dust reduction processes, it is found that the foaming performance of the dust suppressant is good, which will lead to too much foam. After spraying, more foam will be generated, which will affect the wetting behavior of the fog droplets on the dust particles, and even affect the spray dust reduction. Effect
In severe cases, it may even have a certain impact on the normal operation of the spray system
Moreover, too much foam in the spraying process will affect the atmospheric visibility of the operating site to a considerable extent, which will greatly affect the normal production of the operators, and even cause mine safety production accidents.

Abstract

The invention discloses an antifoaming dust suppressant and a preparation method thereof. The antifoaming dust suppressant comprises, by mass, 50-89.99% of a dust suppressant, 0.01-20% of an antifoaming agent, and the balance of water, wherein the antifoaming agent is selected from one or more of alkyl silicone oil, alcohols, castor oil, palm oil and oleic acid. The antifoaming dust suppressant can eliminate foams in the dust suppressant or keep moderate foams in the dust suppressant to guarantee the homogeneousness and the stability of the dust suppressant and the wetting performance of the dust suppressant to dusts.

Description

technical field [0001] The invention belongs to the technical field of mine environmental protection and mine safety production, and specifically relates to a defoaming dust suppressant for spray dust reduction, blasting construction process dust suppression and other wet spray dust suppression and a preparation method thereof. Background technique [0002] Dust is fine particles produced during mine mining, storage, loading and unloading, transportation and stockpiling, which can be suspended in the atmosphere for a long time, causing the visibility of the surrounding atmosphere to decrease, causing operators to suffer from pneumoconiosis, and may lead to mine safety production accidents. According to statistics, among the currently used dust suppression technologies, wet spray dust suppression is one of the commonly used technologies. However, due to the hydrophobic nature of dust particles, water mist can only reduce dust by collision, interception, etc., so that dust par...
