[Vulcanized rubber bearings] [] to the plastic rubber bearing rubber into an elastic rubber process called vulcanization, which is a quantity of vulcanizing agent (such as sulfur, vulcanization accelerators, etc.) was added to the semi-finished products made of raw rubber from (vulcanization carried out in the tank), is heated at a predetermined temperature, thermal insulation, so that linear molecules between raw rubber "sulfur bridges" and cross-linked network structure is established by generating, so that the plastic compound have become vulcanized rubber high elasticity. Since the crosslink bonds are primarily composed by sulfur, so called "curing." With the rapid development of synthetic rubber, vulcanizing agents are now many varieties, in addition to sulfur outer damping bearing steel construction, as well as organic polysulfide, peroxides, metal oxides and the like. [Rubber bearings] Therefore, any make plastic rubber-like structure, into a process of three-dimensional elastic rubber mesh structure called vulcanization, who can play a "bridge" in the rubber material substances are called " curatives. " [] Elastic rubber vulcanized rubber bearings after called vulcanized rubber, also known as soft rubber, commonly known as "rubber." Sulfide is one of the most important processes rubber processing and rubber products must be cured to achieve the desired performance. Uncured rubber is in the use of no value, but less sulfur (degree of cure is not enough, the curing time was not able to achieve the best state) and persulfate (curing time exceeded significantly decreased performance) are the rubber performance degradation. [So] rubber bearing production process must be strictly controlled curing time to ensure that vulcanized rubber products with the best performance and longest life. [] Widely rubber rubber bearing applications, there are many varieties. In accordance with the purpose to points Guangrun excellent quality damping bearings, usually divided into two categories industrial and civil. Industrial rubber products mainly include: tires, belts, hoses, offset, tape and tape products, seals, vibration parts, latex products, hard rubber, rubber insulation products, rubber rollers and rubber lining, etc. (see table below) Plate Installation Precautions] [rubber bearings: 1, placed [] of rubber bearing pads stone surface should be smooth, dry, no quicksand. Support cushion stone top surface height requirements are accurate. In the case of a flat slope of the same below the beam end support cushion and the same stone abutments, support cushion stone pier on the design elevation should be in the same plane, the relative error of not more than 1.5mm, with a cushion should stone error less than 0.5mm. 2, rubber bearing plate [] in the installation process, should be in accordance with design drawings, marked on the support cushion stone bearing centerline position damping bearings to ensure accurate bearings in place. 3] [rubber bearings installed, should prevent the production of excessive bias or appearance of the initial shear deformation. After falling girder beams should not rush to dismantle facilities, until each piece beam falling to carefully check whether the initial laminated rubber bearing shear deformation phenomena (initial shear deformation generally occur in 1-15 days) if there is a certain to be adjusted. This phenomenon is just a little adjustment from the high side of the beam end bearing damping steel product specifications, rubber bearing plate [] will automatically reset at its spring action. 4, in any case, not allow two or more bearings along the longitudinal centerline on the same support points arranged side by side. In a beam with the board, should not be set more than two transverse support. Different specifications of bearings not installed side by side. 5, before the bridge deck to deal with rubber bearing plate [] to carefully check the initial shear deformation and, if necessary to adjust this time frame beam facility has been removed, you can use 100 tons of special jack (Note: jack body height should not exceed 80mm) or the corresponding lifting equipment will end a little from the top side of the beam 2 ~ 5mm laminated rubber bearings should automatically return, or should be replaced.
