Paint on the galvanized layer, the binding force between each other and the baking temperature of the paint has a great relationship, after galvanized coating alkyd paint, adhesion is no problem. Galvanized amino paint, paint adhesion is not good. Do two bottom two surface, adhesion is ok, if the two bottom two surface to two bottom three surface, that is, more paint, more baking once, again test adhesion is very poor, poor to the paint from the galvanized layer of pieces torn off.
Cold wire drawing is a kind of cold processing of metal, that is, we often say reinforcement. Cold drawing process is not messy, cold drawing price based on the quality of cold drawing dividends of different levels, cold drawing production is also a variety of different procedures. The main factor affecting the strength of cold drawing wire is raw materials, which are closely related to the raw materials, strength and diameter of raw materials, and the better the quality of cold drawing wire, the more messy the production process.
Solder spot, size and wire diameter of galvanized electric welding net. There are clear regulations about size and diameter of silk, as long as it meets the standard, there will not be too much difference. Galvanized welding net production is mainly welding, welding point is firm directly determine the quality of the net. Large galvanized wire purchase process need to carefully observe the solder joint, if the solder joint is too shallow, it shows that the welding is not so strong, it is easy to open welding after use.
The strength of the hook mesh should be satisfied: when the vehicle is traveling at 80 kilometers per hour, the hook mesh will not fall into the river when it bumps against the rail at a 15 degree Angle. The shape and color of the hook mesh should be in harmony with the surrounding natural environment. The phenomenon planning of the important Bridges should be done well. When the bridge crosses important traffic lines, such as expressways, urban rail transit, expressways, railway trunk lines, etc., the hook mesh should add the protective mesh on the pavement of the bridge deck.
Different from the general zinc barbed rope, high zinc barbed rope surface zinc content is very high can reach the former 6-8 times, so in the service life also has a great advantage, ordinary products three or five years began to corrosion and the latter will take longer to change. Stainless steel barbed rope is in the material aspect of protection, so the durability is also better, these two products are long in the service life, but in the price is high.
In order to pack and bind galvanized wire in the surface of the sedimentary layer to local removal of surface film, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is formed when soap and surfactants such as saponified fats are brought into the tank. Moderate rates of foam formation may be harmless. Small, homogeneous particles of large denier present in the bath can stabilize the foam layer. Use activated carbon mat to remove surface active substance. Or through filtration to make the foam is not too stable, which are effective measures; Other measures should also be taken to reduce the amount of surfactant introduced. The electroplating speed can be obviously reduced by the addition of organic matter. Although chemical formulations facilitate high deposition rates, the deposition of organic matter does not meet the requirements of coating thickness, so activated carbon can be used to treat the bath.
The application of electric welding mesh is more and more widely, the technology is gradually mature, electroplating rust prevention, plastic coated treatment, used for breeding, grille, plus the frame to make a fence, etc.
Hexagonal net in the landslide value is also quite high, many slopes through the baptism of the rain after this, there may be sediment flow and other disasters to the people’s property lead to a certain loss, with the existence of the hexagonal net, can fundamentally go up to solve the problem, sediment flow when it comes to it can implement effective protection, is the loss of many people to low. The hook mesh was installed on the hillside, still a nice view line. Under the irradiation of the sun, the metal material of the hexagonal net shines brightly, and its beautiful shape is combined, giving the mountain a kind of elegant feeling.
