Furthermore, we studied the influences of the process conditions on WPG of modified fir powder when pyridine was used as catalyst and acidabsorbent.
并在使用吡啶的反应体系下研究了工艺条件对改性杉木粉wpg的影响。

Around 40% of acrylic acid produced is used to make super-absorbent material like that found in nappies (diapers); most of the rest goes into paints and coatings.
大约40%的丙烯酸产品被用于制造高吸水性的材料,像是尿布里用的那种。其余的大多用于制造颜料和衣料。
