bubble effect in aqueous slurry of powder polypropylene (pp) using poly(vinyl alcohol) (pva) as the stabilizer which is used as a sort of raw materials in rotational moulding has been investigated.
研究了以粉状聚丙烯为原料、以聚乙烯醇(pva )为稳定剂的旋转成型浆液料中的气泡效应。
by analysing the bubble effect on sh series opal quartz far infrared heating components, the mechanism of electric energy-saving of the far infrared heating components is studied.
