Design advantages of one layer of rubber and one layer of steel plate:
Rubber cushions pressure, and steel plate rigidity ACTS as a skeleton.
Just like the human body, there are bones, but also meat, to achieve the basic functions of the human body.
Support is used to support the weight of the container or equipment, and make it fixed in a certain position of the supporting parts, but also bear the vibration and seismic load during operation. The rubber support is a tight combination of rubber and sheet steel, used to support the weight of the bridge.
1, adopted by the rubber glue, which is a major factor affecting the quality of plate rubber support, the current due to the intense market competition, customer demand, many rubber bearing manufacturer from the cost reduction, using poor quality rubber, this one can be seen from the appearance, good rubber, the surface of the deep, dark, press with finger can feel a little bit of flexibility, quality almost rubber, surface hair black, without burnish. However, the true quality of gelatin needs to be tested. It is impossible to find quality problems simply from the aspects of compressive modulus of elasticity and shear modulus of elasticity. In general, it is necessary to test and detect the problems of interlayer film.
2, internal steel plate: steel plate is the guarantee of plate rubber bearing capacity, so the steel plate must meet the standard in thickness, material must use finished plate, put an end to the bending plate, in the treatment must do derusting, sandblasting, so as to ensure that the rubber and steel bonding. (some defective manufacturers use scrap iron sheet instead of steel sheet, or use thick steel sheet instead of thin steel sheet, resulting in insufficient product strength and storage, which is prone to serious problems. At present, some places require testing of extreme compressive strength, in order to find this quality defect)
3, production process: plate rubber support is not fully automated production, vulcanization before the steps are basically manual operation, the next piece, cut pieces, lamination and other processes of good or bad and skilled workers have a great relationship. Vulcanization time and temperature control is also very important in the vulcanizing machine, different specifications of rubber support vulcanization time is not the same, if not the corresponding vulcanization time, then it will form a sandwich, the inside of the rubber is not fully vulcanized, affecting the quality of the product.
