moisture retention
1.The moisture-absorption and moisture-retention of the product were also investigated.
2.The moisture absorbability increased with increasing in molecular weight and moisture retention capacity of CM chitosas with the degree of substitution. The CM chitosans with molecular weight from 0 56×10 4 to 8 6×10 4 and degree of substitution greater than 1 0 had better moisture absorption moisture retention capacity than hyaluronic acid.
6.The experimental results show that the sorption properties of JDW-2 for caffeine and theophylline are superior to that of Duolite S-761. The surface area, the moisture retention and phenolic hydroxyl amount of adsorbents jointly influenced the sorption. Though JDW-2 has a lower surface area than Duolite S-761, the former sorbents has a higher moisture retention(42%) and phenolic hydroxyl amount(3.72 mmol/g) as compared to that of the latter.
7.Some results show that physical clay in 0~30cm soil layer of serious desertification grassland decreases by 97.8% and 94.6% respectively compared to steppe and potential desertification grassland, but bulk volume increases by 0.228g/cm and 0.202 g/cm ; saturation moisture retention decreases by 37.9% and 28.2%.
10.Another reason is a patient tired, lack of power, carry momentum decreases, the mobile level of each systems all lowers human body, flowing flesh is in bowel flabby condition, colonic motion is abate, send excrement and urine to pass in the retention period inside bowel long, moisture is absorbed excessive, defecate eduction is difficult.
