Bridge protection system generally do not need to be specially installed special drainage system, the use of hexagonal mesh made of gabion mesh box, the inside of the filler are selected stones, these stones are not easy to wear, and between the stones and stones will retain some gaps, so it is very good to meet the drainage requirements.
When the zinc layer is seriously damaged and endangers the iron matrix, the zinc will produce electrochemical protection on the matrix, the standard potential of zinc is -0.76V and the standard potential of iron is -0.44V. When zinc and iron form microbatteries, the zinc will be dissolved as the anode, and the iron will be protected as the cathode. Obviously, the atmospheric corrosion resistance of hot dip galvanizing is better than that of electric galvanizing.
The shape of the cage has round, square, octagonal, hexagonal and other shapes. Because the circular space uses a large area, it is more suitable for the activities of birds, and it is not easy to get hurt, so it is popular with everyone. A cage is dear to a man who loves birds, for it is inhabited by his master’s birds. If well maintained, it can be maintained for many years. Let’s look at how to maintain the cage.
According to the different technology is divided into different types, you can choose according to your own needs. Has good flexibility and elasticity, the main role of annealing wire is to control its degree of softness and hardness, when the annealing wire is made of steel wire, now more used in the construction industry bundle use, compared with ordinary iron wire is also softer, has a better luster.
Therefore, when zinc reaches saturation in the solid melt, the two elements of zinc and iron atoms diffuse with each other, and the zinc atoms diffused into (or infiltrated into) the iron matrix migrate in the lattice of the matrix and gradually form an alloy with iron, while the iron diffused into the molten zinc liquid forms an intermetallic compound FeZn13 with zinc and sinks into the bottom of the hot-dip galvanized pot, that is, zinc slag. When the workpiece is removed from the zinc leaching solution, the surface of the pure zinc layer is formed, which is hexagonal crystal, and its iron content is not more than 0.003%.
In view of this situation, many manufacturers are committed to ensuring the corrosion resistance of titanium and titanium alloy under the premise of increasing the hardness of titanium alloy, and surface carburizing is one of the typical processing technology means. Similar to the surface carburizing treatment of steel, the surface carburizing treatment of titanium alloy is to make the active carbon atoms, diffusion to the internal of titanium alloy, the formation of a certain thickness of higher carbon content of the carburizing layer, after quenching and tempering, so that the surface layer of the workpiece to obtain high carbon content of titanium alloy wire.
The guide frame of spray hook net wholesale is composed of guide beam and park core pile, their interval distance is about 3 meters, the spacing of guide beam should be about 1 cm higher than the wall. When installing the guide beam, its position should be far away from the net, and the surround-pile should not be expanded, which will make the surround-pile sink or change its shape.
The reason why there are black spots in wire mesh welding is that the action of wire feeding should be timely filled in the melting time, and the development should be appropriate. There is no argon gas, long burning, large current, long distance, blunt tungsten needle and high molten pool temperature are the fundamental reasons for blackening. Continuous burning, is about active welding machine energy selection, machine welding will appear black spots.
