Abstract

In this work, different forms of polypropylene nonwoven sorbents based on the melt-blown method (MB), spun-bond method (SB), and needle punch method (NP) were used as comparative materials. Different forms of polypropylene nonwoven sorbents were evaluated in terms of oil sorption, retention, wetting, and wicking. The analysis indicates that wicking is a result of wetting behavior. Among sorbents, MB possessed higher height for soybean oil and motor oil. Moreover, it takes more time for oil spreading compared with the SB and NP according to different forms of nonwoven sorbents and oil properties. On the other hand, the experimental results revealed that the highest oil sorption and retention were registered by MB, followed by SB and NP. The investigation revealed that different pore sizes, sorbents porosity, and oil properties played an important role in oil sorption performance.

摘要

在这项工作中，基于熔喷法 (MB)、纺粘法 (SB) 和针刺法 (NP) 的不同形式的聚丙烯无纺布吸附剂被用作比较材料。在吸油、保留、润湿和芯吸方面对不同形式的聚丙烯非织造吸附剂进行了评估。分析表明芯吸是润湿行为的结果。在吸附剂中，MB 对豆油和机油具有更高的高度。此外，根据非织造布吸附剂的不同形式和油性，与SB和NP相比，油扩散需要更多时间。另一方面，实验结果表明，MB 的吸油率和留着率最高，其次是 SB 和 NP。调查表明，不同的孔径、吸附剂的孔隙率、
