How to Prevent Corrosion of Wire Mesh Fence?

Fence netting anti-corrosion way had a lot to do with the service life of the fence, a senior engineer said: in general highway guardrail net use fixed number of year in 10 years or so, some not the size of the small manufacturer, occupy the market at a low price, in order to reduce the cost of production of geisha shoddy, use time in 3 to 4 years, can not completely meet the use requirements. The Double Wire Mesh Fencing Supplierreminds all customers that when purchasing railway fencing, they must choose regular and professional manufacturers. They must not buy poor quality products on the cheap.

Also known as a fence, a fence is a metal mesh tightened around a supporting structure to keep people and animals from entering the road.

Separate grilles shall be installed on both sides of expressways and first-class special automobile roads. And prevent illegal encroachment on highway land. One of the guard rest anticorrosive way: leachate, now the domestic more mature leachate method is: powder leachate method, it originates from the fluidized bed method, the so-called fluidized bed is initially used in the Winkler gas furnace for petroleum contact decomposition, and then developed the solid-gas two-phase contact process, gradually used in the metal coating plastic. So sometimes still called "fluidized bed coating method", the actual process is to add the powder coating to the bottom porous container (flow tank), from the blower into the treated compressed air, so that the powder coating to turn to the "fluidized state".It becomes an evenly distributed fine powder. We know solid flow pattern of the fluidized bed is in the second stage (the first stage for fixed bed, the second phase of gas-phase flow transportation), on the basis of the fixed bed to continue increasing velocity (W), bed expansion and loose, bed height increased, each powder particles float, and leave the original position for a certain degree of mobile, has now entered the stage of the fluidized bed.

The BC section shows that the powder layer in the fluidized bed expands, its height (I) increases with the increase of gas velocity, but the pressure in the bed (△P) does not increase, in a certain range of flow velocity changes without affecting the flow required unit power, this is the characteristics of the fluidized bed, is to use this characteristic for the implementation of the coating process. The uniformity of powder fluidized state in the fluidized bed is the key to ensure the uniformity of coating film. The fluidized bed used in powder coating belongs to "vertical fluidization", the number of fluidization must be found through experiments, generally can be coated, the powder suspension rate in the fluidized bed can be up to 30 ~ 50%.

Railway Fence, public buildings double wire mesh fence, and double wire mesh fence are preheated to above the melting point of powder coating after degreasing. After impregnation into a fluidized bed, the plastic powder will stick uniformly, and then plasticized polymer crosslinked flow will level into steel-plastic composite products.
