Matters must be special attention before painting before painting the basic surface to be coated must be processed to reach the surface smooth and clean, is the key to ensure the coating quality. Otherwise slip the ball joint bearing, due to the substrate surface is not smooth, retained harmful substances, ball bearing hinge will seriously affect the adhesion of the coating, the coating flaking prematurely and lose its protective effect. That is carried out prior to painting to perfect surface treatment, to enhance coating adhesion, better play the role of coatings to protect and prolong its life sliding ball joint mount controllable slip, plays an extremely important role. Ball bearing hinge protective effect is good or bad, it was considered one-third coatings, construction of six points, the extent of the visible surface treatment and fine construction directly affects the protective effect, describes the reset means slipping the ball joint holder in accordance with relevant experience, basic surface treatment of major include the following. General use of organic solvent degreasing degreasing, chemical degreasing, ball bearing hinge electrochemical degreasing and emulsifying cleaning degreasing and other methods. The most commonly used organic solvents and degreasing chemical degreasing. Ball bearing hinge is the use of chemical degreasing grease saponification occurs in alkaline medium were removed by saponification oil, it is also called hot alkaline degreasing method slip the ball joint bearing support beam, which works best for degreasing Multi-girder bridge abutment by reducing the number, to simplify seat, making it clear structural system characteristics. Denser arrangement of the main beam structure, the support portion is provided in the bearing beams to reduce the number of which is to make clear way architecture to overcome the negative reaction force bearing arrangement, if the fulcrum of a negative reaction force, part of the bridge structure will unpredictable stress, it is necessary to take special measures for the seat, therefore, should consider limiting the negative reaction force generated architecture. It is possible to reduce the rotation around the beam generated binding. Using the support plate rolling ball bearing hinge axes drink holder can eliminate this problem for non-parallel bridge and wide bridge, beam spacing variations are not parallel beams ball bearing hinge arrangement, according to FIG consider, then, the ball pinned In any case, the same seat on the support lines are arranged in a certain direction want to support. Slip the ball joint bearing support beams, sliding ball joint bearing, Hao-Hao Rubber pass by Hengshui Rubber Company. Hengshui HaoTong Engineering Rubber Co., Ltd.
