本文叙述甲基纤维素(MC)膜的溶胀与温度的关系,加有MC4%、淀粉10%的磺胺片对吸收水分、崩解时限与温度的关系。用1%MC水溶液在培养皿中制成1.41mg/cm~2薄膜,切成1cm~2正方形。将膜置筛网上,浸入水中。自屏幕上的投影像测定在不同温度时MC膜溶胀-时间的线性关系。达到溶胀峰值称为E_(maz),MC 80～120或MC800～1200的溶胀峰值均随温度升高而下降。34℃迅速溶胀,37℃开始降低,40℃更低。加有MC 80～120或MC 800～1200的片剂,随着温度升高其吸收水分量均增多,顺
This article describes the relationship between the swelling of methyl cellulose (MC) film and temperature, with the addition of MC4% and 10% sulfated starch to the absorption moisture, disintegration time and temperature. 1.41mg / cm ~ 2 film was made in petri dish with 1% MC aqueous solution, cut into 1cm ~ 2 square. Place the membrane over the screen and immerse in water. The projection of the self-screen on the screen determines the linear relationship between the swelling of the MC film and the time at different temperatures. The peak value of swelling reached E maz. The swelling peak value of MC 80-120 or MC800-1200 decreased with the increase of temperature. 34 ℃ rapid swelling, 37 ℃ began to lower, 40 ℃ lower. Add MC 80 ~ 120 or MC 800 ~ 1200 tablets, as the temperature increases its absorption of water increased, Shun
