A kind of synergistic moisturizing antifreeze coal dust inhibitor and preparation method thereof

Abstract

The invention relates to a synergistic moisturizing and antifreezing coal dust inhibitor and a preparation method thereof; the technical problem to be solved is to provide a series of coal dust inhibitors with high-efficiency dampening and antifreezing functions by using compound synergistic technology; , film former, penetrating agent, humectant, coagulant, antifreeze and water. It can be prepared by mixing solutions with relevant concentrations, and can also be added while dissolving; its mass percentages are calcium chloride (33%) 22-52, ethylene glycol (10%) 4-16, glycerin (30) 0-8, CMC (2.5%) 1‑26, PVA (1%) 0‑26, PAM (1%) 0‑17, JFC (5%) 3‑19, magnesium chloride (30%) 0‑22. When in use, it can be sprayed directly on coal piles, coal transportation channels, etc. If it is sprayed with fine water mist, it is more conducive to wetting and penetration, and can reduce the amount of water used.

Description

technical field [0001] The invention relates to a synergistic moisturizing antifreeze coal dust inhibitor and a preparation method thereof. Background technique [0002] Coal dust not only causes waste of coal resources and environmental pollution, but also can cause pneumoconiosis and coal dust explosions in miners. The results of the study show that there is a clear relationship between the total airborne particulate mass and the population mortality rate. Data from London, Steubenville, and Philadelphia show that if 100ugTSP is contained in every cubic meter of air, the death rate will increase by 6%. For the elderly and those with respiratory diseases, mortality from emphysema increased by 32%, mortality from bronchitis and asthma increased by 12%, and mortality from cardiovascular disease increased by 9%. In almost every coal yard in my country, there are varying degrees of dust pollution problems, especially in the northern region, when the climate is dry and windy, ...

AI Technical Summary

Problems solved by technology

The main reason is that some dust suppressants have a single function, often fail to achieve the expected effect, and cannot fully adapt to various complex actual situations in reality, and the cost of one-time investment and use of composite dust suppressants is also very high, and ordinary enterprises are unwilling to bear it; , Coal dust dust suppressant has its particularity, not only requires good dust suppression effect, but also does not affect the subsequent processing and utilization of coal

These have affected the practical application of coal dust inhibitors
