Security speed Fence, Guiyang highway fence

Highway fence coating process consists of two phases to complete: the first stage fixed bed phase, the second phase pneumatic conveying stage, continues to increase the flow rate (W) on the basis of a fixed bed, the bed began to swell and loose , bed height began to increase, each powder particles are floated, thus leaving the original location for a certain degree of movement, when they enter the fluidized bed stage. bc segment illustrates the fluidized bed powder layer expands, its height (I) with increasing gas velocity increases, but the bed pressure (△ P) does not increase, change the flow rate within a certain range without affecting the fluid required power unit, which is characteristic of a fluidized bed, took advantage of this feature to implement the coating process. Uniformity of the fluidized bed powder fluidized state is the key to ensuring a uniform coating. On the use of fluidized bed powder coating are "vertical fluidized" fluidization number must pass the test to find out, generally can be applied to the highest rate in the fluidized bed powder suspension of up to 30 to 50 %. Rail fence is a fence along the railway-specific product, which is characterized as follows: 1, rail fence with a mesh lightweight body, clean, beautiful and durable characteristics 2, may be suitable for highway bridge use as anti-cast net. 3, efficient use of dip. 4 years anti-rust, easy accessibility itself, re-use, and can be based on the need for fence relocation 5, are environmentally friendly products, and ultimately recyclable. Highway fence highway fence are characteristic features of a professional for road, highway guardrail products using simple network structure it has a clean, easy to transport, easy to install. China Anping wire mesh fence is the main origin of domestic products, highway fence in many parts of the country adopted highway. Generally speaking, the general highway fence is mainly used for highways, railways, bridges, stadiums, airports, railway stations, service areas, bonded zones, open-air storage field, ports Zhu field fence to use. If the highway fence are using domestic 4mm diameter quality mild steel wire, highway fence is an ideal metal mesh walls, has been widely used in various industries.
