Because the oxide film and the phosphate film also has a protective effect, so that the basic surface to form a protective film, because Yang Ha film and phosphate may enhance the adhesion of the coating and the metal, and there is a very good Chinese Lin Hua and phosphorus of better, high temperature phosphate phosphate coating, ball bearing hinge Chinese phosphate and phosphate low points, and high temperature phosphate and Chinese phosphate better. Ball bearing hinge phosphate coating can enhance the adhesion of the coating and the metal, but also a very good corrosion resistance and heat resistance, corrosion of demanding components, for further Tsang protection, available network salt Wing Xie seat cushioning passivated steel ball bearings, ball bearing hinges often become complex, post phosphate is completed, should be required to protect the ability of steel parts before painting the phosphating treatment under enhanced. Ball bearing hinge on phosphate coating quality testing, failure mostly due to general corrosion caused by unqualified phosphate coating for aluminum and its alloys bearing, oil, rust institutions, should be anodized immediately. Through the years or decades of bridge operations, ball bearing hinge inevitable aging damping steel ball bearings, deformation, dislocation caused by uneven slab and tilt hinge unidirectional sliding bearings caused by vibration and impact force large, damaged produce telescopic device, knocking pain jumping, ball bearing hinge seriously affect the carrying capacity of the slab. Ball bearings from the case hinged on the highway bridge over recent decades used, in addition to the transportation industry standards set forth in the species, there were a few varieties rebate fulcrum bridge superstructure beyond industry standards for the 150 ~ 8000KN bridges, more commonly used ball bearing hinges. Ordinary laminated rubber bearings for smaller displacement of the bridge span and small rubber PTFE slide bearings for large span, multi-span continuous bridge, Charpy and continuous slab structures such as large displacement of the beam, it can laminated rubber bearings used as sliders and other small push and continuous beam traversing T-beams used in the bearing is usually divided into two non-stiffening stiffening drink holder. Only one non-stiffened rubber bearing, in effect, although horizontal force H bearing shear deformation to meet the needs of the ball bearing hinges but in the role of the vertical load bearing R tends to produce vertical deformation is not recommended Other materials, ball joints stiffened laminated rubber bearing self-made in the vertical loads, steel embedded rubber sheet rubber between the limit lateral expansion of convex drum, vertical deformation is reduced accordingly, thus greatly improving bearing vertical stiffness unidirectional sliding hinge bearings bearings _ _ Huainan buy ho-card holder designed to provide free HaoTong by Hengshui Rubber Company.
