Detailed Product Description: | Of ZP-1 flakiness regulation collimator (research and development unit: think twice instruments) First, an overview The flakiness regulation collimator is mainly used for concrete aggregate and grass-roots screening gravel classification. The flakiness criteria instrument method for the determination of coarse aggregate in cement concrete more than 4.75 mm needle and elongated particles content, in percentage terms. Criteria instrument measured flakiness flakiness particles is to use special criteria to measure the minimum thickness of the coarse aggregate particles (or diameter) direction and the direction of maximum length (or width) sizes than small in a certain proportion of particles. 3, the content of the coarse aggregate flakiness flakiness criteria instrument measured particles can be used for the evaluation of aggregate shape and its applicability in engineering. The main technical parameters of the flakiness regulation collimator 1, sheet size, hole width: 3; 5.2; 7.2; 9; 11.3; 14.3mm 2, sheet size, spacing: 18; 31.2; 43.2; 54; 67.8; 85.8mm The flakiness regulation collimator test procedures 1, visually pick out the rules of particles close to the cube shape, will be visually may belong to the aggregate of elongated particles table T0311-2 under the grain size criteria instrument by particles on the specimen identification of needle-like particles, pick The length of the particle spacing and can not be greater than the corresponding the needle regulatory collimator for the needle-like particles. 2 needle Planning collimator spacing non-needle-like particles by particles on the specimen sheet particle identification, singled out the thickness is less than the corresponding hole in the sheet regulation collimator width through the elongated particles . 3, singled out the quality of the needle-like particles and elongated particles in weighing by the grain size, the total mass m1 is. Fourth, the calculation The content of elongated particles of crushed stone or gravel in the needle-type (T0311-1) calculated to the nearest 0.1%. Qe = (T0311-1) Where: Qe. - Specimen elongated particle content (%); m1 - the sample contained needle-like particles and elongated particles, total mass (g); m0 - sample the total mass (g). Note: If you can calculate the percentage of the content of the needle-like particles and elongated particles. Telephone service 0571 -86,688,649 |
