Steel bearings, also known as (grid bearing), is divided into four types: GKQZ seismic steel ball bearing type, GJQZ type damping steel ball bearings, GKGZ seismic steel structure steel ball bearings, GJGZ steel structural damping steel ball bearings. This type of bearing includes a fixed bearing, code GD; unidirectional bearing steel truss supports, codenamed DX; bidirectional bearing the symbol SX total of 22 grade three types, the level of capacity, vertical uplift and bearing overall strength than ordinary bearings have greatly improved. The series of elastic damping element bearing, when the horizontal force is large to some extent, the damping spring is elastically deformed to achieve the start buffer. When the corner structure, the ball is rotated to produce the core, the release of the upper structure generated by the torque. When the earthquake occurred rigid and flexible measures to effect simultaneous damping measures to resist the huge earthquake input energy, which can guarantee the upper and lower relative displacement of reasonable structure, reducing the seismic force amplification factor, but also make the steel to maintain unity. 8-11 degrees can withstand earthquakes, especially in highly seismic area of ??engineering structures epicentral earthquake zones have good seismic damping effect. Oil paint is polymerized oil, catalysts and pigments, etc., paint drying process by automated carbon unsaturated double bond in the fatty acid chain polymerization steel bearing manufacturers, so that became the body structure while curing film, the current domestic production Manufacturers are more protective coatings on the market there are many varieties of different characters, conditions and requirements vary, we can say the market can not find a universal paint, so choose paint material is very important, but as a kind of melancholy The anti-corrosion coatings must have the following performance characteristics. Characteristic has good resistance to corrosion, refers to the corrosive media which it contacts the cured massacre in terms of physical and chemical properties are stable, neither corrosive medium swelling, dissolution, decomposition and destruction, that undesirable deleterious corrosive chemical reactions. Having a small air permeability and water permeability, gas-impermeable coating is not absolutely permeable abutment and seismic steel, it is necessary to select the film-forming material having small gas permeability, and the shielding effect of a paint type. Good character focus and the necessary mechanical strength, smear can firmly leaning in protective basically, is a manifestation of its ability to play a protective role of key factors, should also have certain physical and mechanical strength to withstand at work stress conditions.
