使用电位滴定法测定了30种不同类型的LAG明胶的还原性,并进行了比较。结果表明:不同工艺过程,不同原料所制造的明胶的还原性大不相同。即使是同属于一种类型的惰胶,它们的还原性仍表现出了很大的差别。由于工艺条件的不同,明胶中还原组份的组成和化学本性可以有较大的差别,从而导致明胶的还原性质也会大不相同。这在一定程度上能解释同一类型的惰胶在照相性能上的差别。
The reducibility of 30 different types of LAG gelatin was determined using potentiometric titration and compared. The results show that the reducibility of gelatin made by different raw materials is very different in different processes. Even with the same belong to a type of inert rubber, their reducibility still showed a great difference. Due to the different process conditions, the composition and chemical nature of the reduced components of gelatin can have a big difference, resulting in the reduction of gelatin properties will be very different. To a certain extent, this can explain the differences in the photographic properties of the same type of inert rubber.
