Abstract

Herein, we presented a comprehensive case study on the kaolin suspension derived from mining powder, with a specific emphasis on its mineral constituents within the size range of 2-5 μm and its suitability in spray applications. We have systematically investigated the influence of adjuvants, existing in both organic molecules and polymers, on the sedimentation behavior of clay suspensions. The investigations included the analysis of turbidity, dispersion weight, pH, and surface charge as key parameters. Our findings revealed that the specific presence of PEG-PPG-PEG, PAA, and PSAMA had a notable effect on delaying the suspension of sedimentation by the actual sediment weight as well as enhancing the uniformity of clay coating by the reflection efficiency of coating materials in PPFD units. To enhance sustainability in coating materials, it was essential to elucidate the optimal amounts of adjuvants and the pH levels as they are closely related to the efficacy of tree-coated spraying and soil conditions.

摘要

在此，我们展示了一个关于由采矿粉末衍生的高岭土悬浮液的综合案例研究，特别强调了其粒径在2 - 5μm范围内的矿物成分及其在喷雾应用中的适用性。我们系统地研究了有机分子和聚合物中存在的助剂对粘土悬浮液沉降行为的影响。研究包括对浊度、分散重量、pH值和表面电荷等关键参数的分析。我们的研究结果表明，聚乙二醇 - 聚丙二醇 - 聚乙二醇（PEG - PPG - PEG）、聚丙烯酸（PAA）和聚苯乙烯马来酸酐共聚物（PSAMA）的特定存在对通过实际沉降重量延迟悬浮液沉降以及通过PPFD单位中涂层材料的反射效率提高粘土涂层的均匀性有显著影响。为了提高涂层材料的可持续性，阐明助剂的最佳用量和pH值水平至关重要，因为它们与树木涂层喷雾的效果和土壤条件密切相关。
