The polyimide membrane has high H_2O vapor permeability and can be applied to dehydration of organic vapors, or air drying. 这种膜对水蒸气有很高的透过性,因而也可用于有机蒸气的脱水,或空气干燥。
Through collecting, dehydration, conditioned test and anti-jamming test of the sample, the content of trace urea dust in the air can be exactly determined by way of such technique. 通过对样品的采集、洗脱、消化水解、条件试验及抗干扰试验,证实本法能准确测定空气中微量尿素尘的含量。
This paper presents mainly application of spiral-wound membrane technology in separation of carbondioxide from methane, nitrogen in natural gas, carbon dioxide in hydrogen sulfide, hydrogen sulfide in drilling gas, and dehydration of air, refined gas and natural gas, etc. 本文主要介绍有关卷式膜技术在CO2/CH4分离、天然气中N2的分离、N2S脱CO2和脱除钻井气中H2S等和空气、各种炼厂气和天然气等除湿的应用。
Enzymatic browning normally occurs during dehydration of Amorphophallus albus with hot air, and the quality of the konjac flour is affected. 白魔芋在干燥脱水过程中发生酶褐变,影响魔芋粉的质量。
While sludge is treated by polyacrylamide, course of air dehydration is accelerated obviously and the cycle of air dehydration is curtailed about ten days, the burthen of the drying bed is aggrandized distinctly. 经过投加高分子絮凝剂PAM的污泥,脱水速度加快,干化周期缩短了10天左右,使干化床的负荷能力明显提高。
The damage of apple's vacuole membrane increased. The positive correlation was shown in slice thickness and dehydration rate, the relation of the irradiation dose and the temperature of hot air was negatively correlated. 结果表明:苹果组织结构和液胞膜的损伤程度随剂量的增加而加剧,脱水速率与辐照剂量呈正相关;
The experimental study on mixing dehydration characteristic of far infrared radiation and air convective on mushroom 远红外辐射并配以排湿气流干燥蘑菇片的实验研究
