VTSYIQI Fineness Meter Scraper Fineness Meter Single Fineness Gauge with 2 Scrapers Indexing Value 2.5μm Scale Range 0-25μm Stainless Steel for Printing Ink Paper Ceramics Medicine Etc About this item Single groove Grindometer have only one measuring groove and can only measure the fineness of one type of particle. Range：0-25μm Indexing Value:2.5μm Applications：Mainly used to determine the fineness of pigment and impurity particles in paints, lacquers, inks and other liquids and pastes. overview It is mainly used to determine the fineness of pigment and impurity particles in paints, lacquers, inks and other liquid and other liquids and slurries in the fineness of pigment and impurity particles. The Single Groove Fineness Meter has only one measuring Groove and can only measure the fineness of one type of particle at a time. Specification scale range：0-25 Indexing Value： 2.5μm Recommended range <20 Scraper size: 155*50*12mm Inclined groove size: 120*13mm Maximum depth of groove: 25μm Inclination of groove: 1:4000 Scraper size: 68*40*6mm Standard: GB/T1724-93 Precision (1) Straightness of the upper plane of the scraper 0.003mm Plane straightness 0.002 (within scribe line) (2)Straightness of plane at the bottom of inclined groove 0.003mm Plane straightness 0.002 (within the scribe line) (3) scraper two cutter plane straightness 0.002 mm Glossiness (1) Scraper upper plane 10 (2)Bottom surface of inclined groove 8 (3) Scraper two cutter finish 8 usage The specimen which conforms to the standard viscosity index of the product is fully stirred with a small paint mixing knife, and then a few drops are dropped on the deepest part of the scraper fineness.Stir well, and then in the deepest part of the scraper fineness, drop a few drops of specimen, to be able to fill the grooves and slightly excess appropriate. In order to be able to fill the grooves and a little excess is appropriate.H old the scraper with both hands, place it horizontally on the upper end of the polishing plate (at the edge of the specimen) so that the scraper can be used for the purpose of polishing the specimen.Edge of the specimen) so that the scraper and the surface of the polishing plate vertical contact. In 3s, the scraper from the deep part of the groove to the shallow part of the pull through, so that the paint sample filled with grooves and the plate.Make the paint sample full of grooves without leaving residual paint on the plate. After pulling the scraper, immediately (not more than 5s) Immediately (not more than 5s) make the line of sight at an angle of 15-30° to the plane of the groove. Observe the evenly exposed particles in the groove in the light, and write down the readings (accurate). to the smallest division). If individual particles are exposed on other divisions, the reading is the same as that of the adjacent divisions. If individual particles are exposed on other dividing lines, the reading should not exceed three particles within the range of the adjacent dividing line.
