study on plasma modification process on pbt melt-blown nonwovens and their performances 熔噴非織造布的等離子體接枝改性工藝及性能研究
2 . effects of different coating modification process on coatings defects control and oxidation behaviors of c / sic were studied (2)研究了不同涂層改性措施對涂層缺陷和csic氧化行為的影響。
according to the ftir spectra, the modification process was efficient to coat a layer of stearic acid ( sa ) on the powder surface 根據(jù)紅外光譜分析,在粉末表面施覆硬脂酸或聚乙二醇可有效改變其表面官能基。
the mechanism is discussed briefly . the test results show that original properties of the coatings can be improved by the laser modification processes 試驗證明采用激光重熔對鍍層再處理,可以改善其原有的各項性能。
the modification process achieves the preparation and the modification of silica in one process, which can simplify the production technology of hydrophobic silica 原位改性技術(shù)將白炭黑的制備過程和改性過程一次完成,大大簡化了疏水化白炭黑的生產(chǎn)工藝。
