Problems solved by technology

However, all kinds of dust suppressants have certain defects, such as short dust suppression time, poor bonding performance, etc.
The main components of the composite dust suppressant are nonylphenol polyoxyethylene ether, ethylene glycol, glycerin, etc. The principle of dust suppression is mainly to use the wetting and flocculation of macromolecular organic matter such as glycerin, and these composite dust suppressants All have the disadvantage of "cannot effectively suppress dust", that is, the treatment effect cannot last for a long time
The main reason is that the dust suppressant lacks a strong binder to tightly combine the particles in the fly ash. The particles are small and have poor water retention. The fly ash after dehydration is easy to be blown by strong winds, causing air pollution. Measures must be taken to prevent fly ash contamination

preparation example Construction

[0020] A method for preparing a composite bonded dust inhibitor, prepared through the following steps:

[0021] (1) Put enough water into the preparation tank; (2) Add the coagulant into the water, heat the reaction kettle to 70-90°C, start stirring until the coagulant is completely dissolved; (3) Put the strengthening agent and auxiliary agent in sequence Proportionally added to the container, stirred at room temperature until the product is completely dissolved; wherein by weight percentage: 20-30% of coagulant, 5-10% of strengthening agent, 3-5% of auxiliary agent, and the balance is water; The coagulant is lignosulfonate, and the strengthening agent is selected from one or more mixtures of sodium polyacrylate, polyvinyl alcohol, and polyacrylamide; the auxiliary agent includes sodium carbonate, sodium hydroxyethylene diphosphate mixture, or a mixture of borax and sodium hydroxyethylene diphosphate.

[0022] The lignosulfonate is M t =2500~5000 sodium lignosulfonate or / an...

Abstract

The invention discloses a composite adhesive type dust flying inhibitor and a preparation method thereof. The composite adhesive type dust flying inhibitor is used for sand fields and soil fields on construction sites as well as coal fields, ash fields and raw material, mineral powder and ash slag yards of enterprises and is prepared from the following components in parts by weight: 20-30 parts of coagulant, 5-10 parts of enhancer, 3-5 parts of promoter and 55-72 parts of water. Practice shows that after the composite adhesive type dust flying inhibitor is sprayed in the coal and mineral powder yards, a layer of cured film can be formed on the surface of the ash field, and the film is uniform in thickness, high in viscosity, good in stability, has certain environmental adaptability and can be used for effectively reducing pollution to the surrounding environment and dust flying loss in the storage and transportation processes of coal, mineral powders and the like. As the cured type dust flying inhibitor and components thereof do not have toxic or side effects or corrosion effect, are low in cost, are economical and easily available, the cured type dust flying inhibitor is an effective, economical environmental-friendly cured type dust flying inhibitor.

Description

technical field [0001] The invention relates to a composite bonded dust suppressant and a preparation method thereof, which is used for controlling the dust problem in sand fields and soil fields of construction sites, coal yards, ash yards of enterprises, and accumulation places of raw materials, mineral powder and ash. Background technique [0002] In today's society, air pollution has become one of the most serious environmental pollution. Under the influence of factors such as wind force and transportation, the floating soil and dust that are inevitably produced at the construction site and the ash accumulation place of the enterprise seriously pollute the surrounding environment, which is one of the main causes of disastrous weather such as smog, endangering residents and The health of workers affects the growth of surrounding animals and plants, destroys the ecological balance, and has extremely bad social impact. In addition, the dust in the ash field has caused grea...
