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 seismic ball bearing steel hinges suppliers, due to the substrate surface is not smooth, retained harmful substances, ball bearing hinge will seriously affect the adhesion of the coating, the coating peeling off 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, 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, according to the experiences, the basic surface treatment 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, this oil works best because the oxide film and phosphate film also has a protective the role of the basic surface to form a protective film on seismic steel ball bearing hinge, as Yang Ha film and phosphate may enhance the adhesion of the coating and the metal, but also good is Lin Hua and Chinese phosphide better Seismic finished steel bearing ball joints, high temperature phosphate phosphate coating, ball bearing hinges Chinese phosphate and low phosphate points, while the high temperature phosphate and Chinese phosphide better. Ball bearing hinge phosphate coating can enhance the adhesion of the coating and the metal, but also good corrosion resistance and heat resistance, corrosion demanding for members to further Tsang protection capability, available network salt Wing Xie seat passivation, ball bearing hinge often become complex, post completion of the seismic phosphate steel ball bearing hinge manufacturers 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, degreasing, descaling institutions, should be anodized immediately. Through years or decades operated bridges, ball bearing hinge inevitable aging, deformation, dislocation caused by uneven and inclined beam and slab, causing vibration force and impact force increases, resulting in damage to the telescopic device, knocking pain jumping, Ball bearing hinge seriously affect the carrying capacity of beam and slab.
