Fence netting anti-corrosion treatment methods and the relationship between the service life is what?
Hulanwang anti-corrosion treatment, according to scientific testing methods and the relationship between the service life, generally speaking: highway guardrail net use fixed number of year in 15 years or so, have no the size of the small manufacturer, occupy the market at a low price, in order to reduce costs, the fence mesh products shoddy, use time in 2 to 5 years, completely unable to meet the use requirements.Here we tell our customers, so buy guardrail nets must choose regular professional manufacturer of high quality products.During the fence mesh jinsu, passes through two stages, and the first stage for fixed bed, the second phase of airflow conveying stage, on the basis of the fixed bed continue to increase the 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 fluidized bed.BC period of powder in fluidized bed expansion, its height (I) increases with the increasing of gas velocity, but bed (delta P) does not increase, the pressure changes within a certain range velocity without affecting the fluid power unit, the this is the characteristics of the fluidized bed, it is to use this feature to applied on the coating process.The uniformity of powder fluidized state in the fluidized bed is the key to ensure uniform coating.On the powder coating with fluidized bed belongs to "vertical fluidized", fluidization number must be tested to find out, generally to coating, powder suspended in fluid bed rate of up to 30 ~ 50%.Usually put the frame fence mesh through above in addition to the melting point is preheated to powder coating, plastic powder will be uniform adhesion after dipping into the fluidized bed, and plasticizing of polymer crosslinking flow pp.47-53 gangsu composite products.Fence netting corrosion one way: jinsu, domestic mature jinsu trick now is: powder molding, it originated in the fluidized bed method, the so-called fluidized bed was originally on the winkler gas generator used in oil contact decomposition, then develop the gas solid two phase contact process, after gradually used in metal plastic coated.So sometimes still called fluidized bed coating method, the actual process is add powder coating to porous permeability at the bottom of the container flows (tank), by the blower from the bottom into the compressed air after processing, make the powder coating turning to "fluidized state".Become a uniform distribution of fine powder.
