Wire Cages are professionally manufactured, constructed from galvanized or stainless steel and welded for structural stability.

Yuanchen manufactures a wide range dust collector filter cages to fit all baghouse makes and models. We can also manufacture uncommon and specialized cage designs as required.

The fabrics of Aramid Needle Felt is not flammable nor ignition, suitable for high temperature environment.Aramid (commonly known as: aromatic polyamide fiber), long-term temperature 204 ℃, instantaneous temperature 240 ℃, alkali resistance strong, medium acid resistance, is the treatment of 180-220 ℃ high temperature gas good material.

FMS Needle Felt has functions of polishing, filtering, sealing, gasket, insulation, shockproof, damping, oil protection, heat insulation, etc.

Denitration in different industries is also being carried out one after another. The temperature, ash and alkali metal content of their flue gas are very different. The alkali content of flue gas in many industries is much higher than that of pulverized coal power generation denitrification. Therefore, it also poses a new challenge to the problem of alkali metal poisoning of the SCR vanadium-based denitration catalyst. Especially in industries such as cement kilns, iron and steel sintering machines, coking plants, alumina clinker kilns and biomass boilers, and high-alkali coal power generation, it is necessary to attach great importance to the poisoning risk of alkali metals in flue gas denitration to denitrification catalysts.

Since the white fiber is produced by the film splitting method, the dispersion in fineness is relatively large, generally from 2dtex to 10dtex. The brown fiber is wet-spinned, so the fiber fineness is relatively fixed. At present, it is 3.3dtex in foreign countries, and the single yarn strength is generally above 4dtex in China. The length is generally 51mm~75mm. The melting point of PTFE is 327 °C, and it can be used for a long time at a high temperature of 260 °C, and the instantaneous use temperature can exceed 300 °C. PTFE cannot burn, and its limiting oxygen index reaches 95%. The strength is low and the breaking elongation is small. The breaking strength of the imported brown fiber is only 1.9cn/dtex, while the strength of the white imported fiber basically does not exceed 4cn/dtex. The friction coefficient is low, so the dust is easy to fall off on the surface of the filter material. The surface tension of the fiber is large, and it has good water repellency. The fiber is finer, the filtration efficiency is average, and the filter material has a weight of 750-800g. The textile performance is not good, the cohesive force is low, and static electricity is easily generated in the fiber spinning process.

The chemical name of PPS is polyphenylene sulfide. It is a white material with excellent thermal stability. Although it will burn when it is placed in a flame, the combustion will stop immediately when the flame is removed. It will show a yellow-orange flame when it burns, and a trace of black will be generated. Soot does not fall off the burned material, and forms residual coke, showing low flame spread and smoke density. The limiting oxygen index is 34-35. The most commonly used fineness is: 2.2 dtex. Other finenesses are: 1.1 dtex 1.7 dtex 3.0 dtex and so on. The most commonly used lengths: 51mm and 60mm. The working temperature is 130～160℃, the short-term working temperature is 190℃, and the melting point is 285℃. In addition, the oxygen content of the fiber should be less than 8% during normal use. The higher the oxygen content, the use temperature should decrease accordingly.
