Ceramic rubber composite plate is the use of advanced thermal vulcanization process, alumina ceramic plate or Mosaic or spherical wear-resisting ceramic block rubber vulcanization together, so as to form a composite wear-resisting ceramic rubber composite plate.He combines the advantages of high hardness of ceramics and high buffering and fatigue resistance of rubber, which can well solve the problem of anti-wear of equipment in the process of conveying bulk materials.The addition of rubber, in addition to the composite plate has a good anti-wear and anti-corrosion effect, but also to prevent material accumulation and blockage caused by the shutdown and effectively reduce the environmental noise.Ceramic rubber composite plate is divided into two and three in one.Two in one refers to the ceramic rubber composite plate, for a two-layer structure, mainly used for easy installation of parts and parts with an arc shape, such as the circular cone, belt conveyor driving roller.The connection mode of two-in-one ceramic rubber composite plate adopts special rubber adhesive, and the composite plate is bonded to the steel plate of the equipment with high strength adhesive to form a strong and buffering anti-wear layer.Three in one refers to the ceramic - rubber - steel composite plate, for the three-layer structure, three in one composite plate with bolts, easy to install, mainly used for square chute, blanking pipe, block material blanking point protection, wharf transport equipment, mine operation equipment.
1. Appearance inspection
Randomly pull out a piece of equipment box to be issued and check:
A. the flatness of the ceramic and rubber composite plate, without obvious deformation, so use the steel ruler to measure the external dimension and diagonal;
B. Check the appearance of the ceramic sheet embedded with rubber, whether there are missing angles, cracks and whether the surface color is consistent;
C. Check the bond between rubber plate and steel plate, and pull the rubber plate around the steel plate by hand to see whether there are warped edges and the bond is firm.
Check the four bolts for mounting on the back of the steel plate.
2. Laboratory testing
After the above appearance inspection is qualified, it can enter the laboratory for testing. If the appearance quality is not qualified, it needs to double the quantity of sampling inspection. If the appearance after multiple batches of sampling inspection pass rate is less than 90%, the product will be scrapped.
A. Take A ceramic piece from the sampled ceramic rubber composite liner and grind it into pieces, and test the curing aluminum content by chemical method;
B. Then take a ceramic piece from the ceramic rubber lining board and test the surface hardness, compressive strength, bending strength and water absorption of the ceramic piece through the test bed.
C. It is qualified to test the adhesive relay between rubber sheet and steel plate through a specific experimental tension machine and meet the requirements of the technical agreement of the contract;
D. Take a piece of rubber from the ceramic rubber composite liner board, and through multiple bending, the rubber will not break, good elasticity is qualified.
E. Conduct chemical test on the rubber, and the rubber is qualified if all indexes meet the requirements of the qualification requirements.
After passing the municipal test, all indicators shall meet the contract requirements. If the pass rate of spot inspection is less than 90%, the product shall be scrapped
