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 a defoaming dust suppressant and a preparation method thereof. The defoaming dust suppressant is composed of the following raw materials according to mass percentage: dust suppressant 50-89.99%; defoamer 0.01-20%; the rest is Water; wherein, the defoamer is selected from one or more of alkyl silicone oils, alcohols, castor oil, palm oil and oleic acid. The defoaming dust suppressant provided by the invention can eliminate the foam in the dust suppressant or keep the foam in the dust suppressant moderately, so as to ensure the homogeneity, stability and wettability of the dust suppressant.

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 type dust suppressant used for spray dust reduction, blasting construction process dust reduction and other wet spray dust reduction and a preparation method thereof. Background technique [0002] Dust is a fine particulate matter produced during mining, storage, loading, transportation, and stockpiling. It can be suspended in the atmosphere for a long time, causing reduced visibility of the surrounding atmosphere, causing operators to suffer from pneumoconiosis, and may lead to mine safety production accidents. According to statistics, among the currently used dust reduction technologies, wet spray dust reduction is one of the commonly used technologies. However, due to the hydrophobic nature of the dust particles, the water spray can only use collisions, interceptions and other effects to make the dust particles...
