在粘胶纤维的生产过程中,粘胶粘度的测定通常采用落球法。该方法简便、实用,但实际操作时却不易看清落球过程。尤其是用来测定下落时间小于10秒的粘胶试样时,观察记录就更难。从而影响测定数据的准确性。为测试方便、准确,我们对原测定装置进行了改进,改进后的粘胶测定器由两部分组成。 1.光源室:可用木板或硬纸板做成空心的长四方体,高300mm,长、宽各大约200mm(以灯泡的体积来确定)。内壁全部涂成白色,最好能嵌上玻璃板。前面正中开一条透光窗,窗宽15mm,窗高250mm,距上下两端各为 In the viscose fiber production process, viscose viscosity is usually measured by the falling ball method. The method is simple and practical, but the actual operation is not easy to see the ball falling process. Especially when used to determine viscose samples with a drop time of less than 10 seconds, observation is harder. Thus affecting the accuracy of the measurement data. For the convenience and accuracy of the test, we improved the original measuring device. The improved viscometer consists of two parts. 1. Light source room: made of wood or cardboard hollow rectangular, high 300mm, length, width of about 200mm (to determine the size of the light bulb). All painted white walls, the best can be embedded in the glass. In front of a transparent window to open a window width 15mm, window height 250mm, from the upper and lower ends of each
