[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, there are 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 GYZ selling high quality laminated rubber bearings, 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 purposes of points, 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) Issues] [rubber bearing calculation should be noted that the actual maximum bearing deformation will also significantly less than the # 4 and # 6 Pier 1. [Rubber] the effective pressure bearing area Ae bearing stress calculation, should adopt effective pressure bearing area (ie pressure stiffening plate area). Similarly, the shape factor when calculating the bearing, should adopt the stiffening plate size calculation. Old Bridge bearing the appearance of size regulation is substituted into the calculation, should pay attention to adjust our calculations habits. 2. ] [Rubber bearing shear modulus Ge at room temperature shear modulus rubber bearing Ge = 1.0MPa. The actual design, Ge value should be noted by the bridge site area to adjust temperature conditions. When the average temperature of the coldest month Leinian average of 0 ~ -10 ℃ when, Ge value should be increased by 20%; when below -10 ℃, Ge value should be increased by 50%; when less than -25 ℃ , Ge value using 2.0MPa. 3. ] [Rubber bearing rubber layer thickness te total proceeds to calculate the thickness of rubber bearings, easily mistaken for a seat te total thickness t, in fact, should be [te] The total thickness of rubber bearing rubber layer, that te = t -nt0. Where n is the cradle steel stiffening layers; t0 is the thickness of each layer of stiffening plate. "Building absorber device" patented technology invented laminated rubber bearing is to fundamentally solve the earthquake broke out on the basis of building security in the form of a building within a certain distance around the edge of laminated rubber bearing installation and maintenance On the basis of the position of the bottom surface of the ground, set the "building absorber device" good GYZ circular laminated rubber bearing performance, the role of the device is completely cut off from any direction seismic shocks based power transmission line, so that the foundation is in safe protection among the base are safe, and the upper part of the building naturally safe. Laminated rubber bearing, laminated rubber bearing installation and maintenance, homegrown (certified merchants) provided by Hengshui Rubber Co. Guangrun. Hengshui Guangrun Engineering Rubber Co. (www.grgcxj.cn) is specialized in the "seismic steel ball bearings, spherical steel unidirectional bidirectional slide bearing, fixed-elastic damping ball bearing hinge" of the enterprise, the company is adhering to the "integrity management , hard service "concept, to provide you with the highest quality products and services.
