Abstract

The invention relates to the technical field of dust fall, and particularly relates to a dustfall agent. The dustfall agent is prepared from the following raw materials by weight percent: 10-20% of onylphenol polyoxyethylene ether OP-10, 5-10% of alkyl alcohol polyoxyethylene ether AEO9, 4-8% of sodium dodecylbenzene sulfonate LAS, 2-5% of glycerinum, 1-5% of sodium tripolyphosphate STPP and the balance of water. The raw materials disclosed by the invention can be biodegraded, do not damage vegetation, are safe in ecological environment, belong to environment-friendly materials, and do not form secondary pollution after being used. Metal equipment can be effectively prevented from being corroded by water by a corrosion inhibitor added to the dustfall agent, and the service life of the equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of dust suppression, in particular to a dust suppression agent. Background technique [0002] At present, the known dust suppressants for production environment mainly use the wetting and adhesion of water to effectively intercept, moisten and adhere dust, so that the dust absorbs water and increases in weight, accelerates coagulation and rapid settlement. In order to save water and efficiently reduce dust, pressurized atomization technology is usually used to atomize water, and the contact area between water and dust is doubled to achieve the purpose of effective dust capture and accelerated dust reduction. However, in practical applications, some dusts are hydrophobic, such as coal dust, which has poor water wettability, resulting in poor dust wettability and unable to reduce dust. Contents of the invention [0003] In order to solve the problem that the existing dust suppressant cannot suppress the h...
