With an aim at the dust problem of open dust sources in construction sites, open stockyards, mines, docks, and other areas, a polymer chemical dust inhibitor was developed in this study that is suitable for stockyards through theoretical analysis and laboratory tests. Through a single-factor experiment and an orthogonal experiment, the viscosity value of dust suppressant and the hardness value of the crust taken as evaluation indexes, the optimal formula of dust suppressant for a pile was finally obtained after an analysis of range and variance: the optimum formulation of the dust suppressant for stockpiles was finally obtained by: 0.6%A + 0.2%B + 0.28%C + 0.7%D. The performance of the dust suppressant was characterized. The results showed that the longer the suppression time of suppressants, the better the weather resistance and environmental friendliness. Polymeric dust suppressants for stockpiles can effectively suppress the open dust, improve the air quality, protect the climate environment, and maintain people's health and have a certain industrial application prospect.
针对建筑工地、露天堆场、矿山、码头等区域开放性扬尘源的扬尘问题，本研究通过理论分析和实验室试验，开发了一种适用于堆场的高分子化学抑尘剂。通过单因素试验和正交试验，以抑尘剂的粘度值和结壳的硬度值为评价指标，经极差分析和方差分析，最终得出了针对料堆的抑尘剂最佳配方：0.6%A + 0.2%B + 0.28%C + 0.7%D。对该抑尘剂的性能进行了表征。结果表明，抑尘剂的抑尘时间越长，其耐候性和环境友好性越好。堆场用高分子抑尘剂能够有效抑制开放性扬尘，改善空气质量，保护气候环境，维护人们的健康，具有一定的工业应用前景。
