Wall bricks dedicated tryout

A mold, the second mold is based on GB / T 2542-2012 Test methods for wall bricks and GB / T 25044-2012 compressive strength of masonry brick sample preparation equipment to make the general requirements. Second, a mold and secondary mold: 2.1 forming a tryout assembled cavity dimensions are: length 120mm width 120mm; height 115mm 2.2 tryout assembled secondary molding cavity dimensions: length 240mm width 120mm); After 65mm. Three high, forming mold and the second mold of 3.1 tryout molding assembly, wipe brush with lubricating oil, then put the sample into the test mode in the bricks in the middle and both sides of the insert plug board to determine the thickness of the front and rear direction with rubber seal, tighten the screws initial sample, remove the flapper and eventually tighten the screws. The tryout fixed samples into a shaker adding special paste sample preparation. 3.2 Secondary forming tryout assembled, wipe with a lubricating oil brush, into special paste material, and then put the brick on the test sample into the mold of the top wire, the top wire to ensure the paste thickness not exceeding 3mm, screw the test like fixed onto the vibration table vibration, to be a net after hardening paste material on the other side were re Chaimo Four process, a secondary molding mold and die maintenance after the end of the tryout use, the surface of the blade tryout clean, then rinse with a lubricating oil applied to facilitate the next use.
