恩氏粘度,是明胶的一个重要技术指标。关于固体明胶恩氏粘度的测定,已有了确定的方法。由于在溶液状态下明胶的恩氏粘度容易遭受损失,因此有必要探讨明胶溶液的恩氏粘度,以利采取有效措施防止其损失。一、在相同比重下,恩氏粘度与“恩氏秒数”(即在恩格勒粘度计上测出的秒数)的关系选择几种恩氏粘度不同的固体明胶,将其准确搭配成恩氏粘度顺次相差1°E的若干样品。然后各取一部分,分别溶解并调成在50℃时具有相同比重的溶液,再按照固体明
Engler viscosity, gelatin is an important technical indicators. Determination of solid gelatin Engler viscosity, there have been identified methods. Due to the easy loss of Engel’s viscosity of gelatin in solution, it is necessary to investigate the Engel’s viscosity of gelatin solution in order to take effective measures to prevent its loss. First, in the same proportion, Engler viscosity and “second” (that is, the number of seconds measured in the Engler viscometer) the relationship between the selection of several different viscous Entagen solid gelatin, with accurate match Engler viscosity sequential difference of 1 ° E of a number of samples. Then take a portion of each, respectively, dissolved and transferred into a solution having the same specific gravity at 50 ° C, followed by solid
