During transportation and storage, coal produces a lot of dust, which pollutes the environment and threatens the occupational health of workers. Although many dust suppressants have been developed for dust prevention at work, the implementation of current dust suppressants does not meet the requirements due to various factors such as the hydrophobic nature of coal dust and a harsh external environment. In this study, hydroxyethyl cellulose, acrylamide, and stearyl methyl acrylate were used for micelle polymerization to prepare an environmental protection dust suppressant for preventing dust during coal storage and transportation. The microstructure of the reactants and the products was analyzed by Fourier transform infrared as well as scanning electron microscopy. The strength and self-healing tensile properties of binder coal were taken as indicators to determine the best synthesis dosage and conditions. The dust suppressant particles are applied to the dust accumulation area, contact each other after water absorption, and swell to complete the healing, to achieve the purpose of dust control. The evaluation of the relevant properties of the dust suppressant reveals that the dust suppressant has a good covering effect, an excellent dust suppressant performance, and a significant dust suppression action.

基于自修复凝胶的新型高效煤尘抑制剂的合成与性能。

在运输和存储过程中,煤炭会产生大量粉尘,这会污染环境并威胁工人的职业健康。尽管已经开发了许多用于工作中的防尘的粉尘抑制剂,但是由于各种因素,例如煤粉尘的疏水性和恶劣的外部环境,目前的粉尘抑制剂的实施不能满足要求。在这项研究中,羟乙基纤维素,丙烯酰胺和硬脂基丙烯酸甲酯被用于胶束聚合反应,以制备一种环保的抑尘剂,以防止在煤炭储存和运输过程中产生粉尘。反应物和产物的显微结构通过傅里叶变换红外光谱和扫描电子显微镜分析。结合煤的强度和自愈抗拉性能作为确定最佳合成用量和条件的指标。将抑尘颗粒涂在集尘区,吸水后相互接触,溶胀膨胀,完成愈合,达到控制粉尘的目的。对防尘剂的相关性能的评估表明,该防尘剂具有良好的覆盖效果,优异的防尘性能和显着的防尘作用。
