Hexagonal net value is quite high in landslides, many slope through the baptism of the rain after this, there may occur sediment flow of plague and as a result some losses to the property of the people, have the existence of hexagonal wire netting, can solve this problem, from the fundamental up sediment flow in came it can help guard against protection, achieve low is the loss of many people.

Galvanized hexagonal net features: easy to use; Save transportation costs. It can be reduced to small rolls and wrapped in moisture-proof paper packaging, taking up less space. Coating thickness uniformity, stronger corrosion resistance; Simple construction, no need for special technology; It has strong ability to resist natural damage, corrosion resistance and adverse weather effects; Can withstand a large range of deformation, but still does not collapse. Fixed heat preservation and heat insulation effect.

Galvanized diamond net to reduce the impact of the project on the environment, protect the slope protection area of the land, maintain the rock can be fully strong, slope protection hook net through artificial planting grass planting, the implementation of green function. Suitable for any complex terrain, at the same time, does not destroy the original landform, the product is mesh distribution, visual interference, convenient for artificial afforestation, conducive to the environment, engineering and environment integration system flexibility.

3, with oil cloth (oil used cloth), carefully from inside to outside, including each cage wire repeatedly grinding many times. The front of the bird cage, the door flowers, where vision is often in place, are repeatedly rubbed in order to improve the surface finish, equivalent to “grinding”. Note: door flowers, arhat lines and other structures are delicate and fragile, do not break. This process, which requires time and patience, care, is also a process of observing and appreciating the cage. Use new cloth again, according to the above process, wipe again and again. This process is equivalent to polishing. For important parts, you can use a little force, the speed can be a little faster (do not use force). Be careful to fold the cloth neatly, otherwise marks will easily form. When this process is complete, the surface finish is significantly improved.

Compared with galvanizing, hot-dip galvanizing has lower production cost and less environmental impact than galvanizing. Because the coating obtained is thicker, hot-dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for steel parts used in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, ocean exploration, metal structure, electric power transmission, shipbuilding and other industries.

If the zinc coating is good, but when the light comes out in 3% nitric acid, there is a dark shadow on the coating, and the film is brown when passivation occurs, which may be caused by foreign metal impurities such as copper or lead in the galvanized liquid. When there is a problem in the process of galvanizing, check the temperature and current density first, and then measure and adjust the content of zinc and sodium hydroxide in the bath through the analysis of the bath. Whether DPE levels are low can be determined by Hull cell test.
