Camera settings: Set the brightness of CCD (according to the brightness of the test environment for a reasonable set), began experimenting :( corresponding toolbar button) tested in accordance with the test set in the configuration menu set a good total sampling rate and sampling. Stop experiment: After starting the test before pressing Dongguan droplets angle measurement experiment is completed, pause sampling images. Turn on the camcorder: Open CCD lighting test. Turn off the camcorder: Close CCD daylighting price drops angle measurement can not be sampled. Record Video: Click recording video, establish the name of the video, choose a location for the video, the whole process of testing to shoot. Powder drop of water contact angle measurement angle measurement date where the contact angle on solids can be directly and accurately measure (the company produced JC2000 contact angle measuring instrument can be measured), but the powder samples, due to fine particles surface is not smooth, can not be measured directly, only indirect measurement. Existing two kinds of measurement methods for compression method and osmosis. Tablet method is to measure the contact angle required powder by a tabletting machine and compressed into tablets, and then measuring the contact angle measurements on solid; permeation method is the inner diameter of the powder contained in a hollow tube of uniform compaction, by compacting the powder bed was measured in the liquid permeation speed in which the contact angle was measured. Penetration method requires a reference for the perfect wetting liquid ratio. Washburn equation provides us with a wetting contact angle measurement principle. Droplets angle measurement function, ShengDing instrument (certified), drop angle provided by the Dongguan Sheng Ding Precision Instrument Company. Dongguan Sheng Ding Precision Instrument Co., Ltd.
