Bridge protection system generally do not need to install special drainage system, the use of hexagonal mesh gabion cage, the filling is selected stones, the stones are not easy to wear, and between the stones and stones will retain some space, so it is very good to meet the drainage requirements.

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%.

With the improvement of people’s living standards, now many families are raising some small pets, these small pets need a stable nest, pet cage has become a more important choice of people, each pet habits and living habits will choose to adapt to the cage.

With the development of mining industry, pig iron classification in Our country has been very extensive, can satisfy the demand of machinery industry. In general, iron used to produce large coils of galvanized wire can be divided into two classes. A metal produced directly from iron ore and iron smelting, consisting of iron oxide, silicon dioxide, and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed in, so that the refined material is called general pig iron, is also for the initial grade of the material.

Annealed wire is mainly made of soft iron wire through low carbon steel heating, hot drawing, constant temperature and other processes. Because of the differences in use, there are also different in the production process, and the specifications are varied. Annealed wire can be widely used, mainly because annealed wire and other kinds of wire, has many advantages.

The cage door must be open so that the puppy can get out at any time. Once the puppy gets used to the dragon, it will go in without you urging it. Close the door for a few minutes when the puppy is having fun. But keep the crate in a busy area of your home, such as the kitchen. The puppy is relaxed and asleep in the safety of its cage. Cage trained puppies should not be caged for more than two hours during the day (unless you have to, but as soon as you get home from work let the puppy out). After getting used to the crate, the puppy is willing to stay in the playpen. Some dogs can’t stand the small space in a crate, but puppies are less likely to have this problem.

Immersed six edge barbed wire corrosion lost the original characteristics, in the shape, color and mechanical properties and other aspects will change, resulting in equipment damage, pipeline leakage, specifically, is prone to fracture, lose the original protection function. Corrosion usually metal corrosion has three types: physical, chemical corrosion and electrochemical corrosion, and corrosion depends on the chemistry of the metal itself and the organizational structure, still have relationship with the surrounding medium, such as wet environment than dry environment is easy to rust, more less than the impurities of impurities is easy corrosion, high temperature conditions than under the condition of low temperature corrosion, etc. After understanding these, we can effectively prevent the corrosion of the six sides of the wire, prolong the service life of the product.
