"Technical Parameters: The implementation of standards; GB/T1724-89 Range: 0-25, 0-50, 0-100 Minimum division value: (2.5, 5, 10)mm Structure size: QXD scraper 155 * 50 * 12mm Material: Cr12 molybdenum vanadium / stainless steel Product Introduction： Fineness board for the production, storage and application of dispersed products in the process of fineness testing, such as applied to: paint, plastic, paint, printing ink, paper, ceramics, medicine, food, etc.. purpose Fineness dispersion meter using the national steel (molybdenum vanadium) specified this product with stainless steel, used for the determination of pigment and impurity particles coating, paint paste, ink and other liquid and slurry size and dispersion degree, so as to control the quality of the products should be dispersed in the production, storage and use, such as paint, plastic, paint, printing ink, paper, ceramics, medicine, food and other fields. Operation Method: The test details refer to the current version of the British standard BS3900C6, the international standard ISO1524, the ASTM-D 1210 standard and some other domestic standards. The term ""grinding fineness"" is defined as the reading on the fineness plate under certain test conditions, which indicates the depth of the abrasive particles dispersed in the case of the solid particles. The abrasive particles used must be clean and dry, placed on the flat surface. The test activities as a test material is poured into the bottom of the groove, the hands holding the blade by the right angle, speed and smooth vertical pressure to the fineness of plate blade with enough downward pressure to clean the surface of grinding the particles at the same time, the groove is filled with particles.
