Small amount of metaphosphoric acid is produced and remained on fiber.

磷酸致孔的機理主要是磷酸珠粒的阻礙造成類石墨微晶片層發(fā)展不完善，堆疊時發(fā)生扭曲或形成缺陷久久国产乱子伦精品，磷酸與纖維素分子的酯化對微孔的生成有影響超碰中文字幕。

Excellent adiabatic design reduces heat loss and temperature recovering time greatly, ensures no pollution in loading area, and staff can be far away from metaphosphoric acid harm.

良好的隔熱設計減少了熱量的損失并減少了溫度恢復時間，保證裝載區(qū)無污染强奸电影网站，使操作人員遠離偏磷酸的危害

The optimum conditions for making microspheres were obtained via orthogonal experiment with adsorptive capacity as the index as follows: the mass fraction of water phase is 2%(ratio between starch and β-cyclodextrin is 1:2), 110 mL oil, 3.3 g Span60, 6.6 g Tween60, 15 mL water, 18 mL assistant surfactant, 0.07 g metaphosphoric acid trisodium salt. The microspheres were characterized by microscope and the average particle size is about 329.3 nm with productive rate of 41%.
