Advantages of PTFE membrane compared with traditio

(1) the surface filter of bag dust collector is realized, and the dust collecting efficiency is high
Because of the small pores of the film, the PTFE film filter can not penetrate the film and the substrate. Both coarse and fine dust, surface deposition in the film, because the film is not sticky, hydrophobic and stable chemical properties, accumulate easily cleared in the dust layer on the surface of the film so that the filter without filter initial period, is the beginning of the effective filtration, real surface filtration the bag dust collector and excellent bag dust removal efficiency (up to 99.99%).China Manufacturers Custom Hydrogen Stainless Steel Alloy Vacuum Sintering Furnace
(2) low voltage and high throughput continuous operation filtering is realized
The traditional way of deep filtration filter for extremely easy to cause the blocking phenomenon leads to the decrease of the dust collecting efficiency of dust removal equipment, and polytetrafluoroethylene film filter depending on the quality control of man-made a layer of dust, which is put into use, immediately to the excellent filtration efficiency, dust reaches a certain thickness, it will automatically fall off. Easy cleaning, the filter pressure is always kept in a very low level. The air velocity is always kept at a high level. The test results show that the filter wind speed can reach 3.5m/min at 25 125Pa pressure difference. Under the condition of low pressure difference and high flux, the filter dust collector can realize continuous power filtration.
(3) recoil pressure is low, velocity block
The operation pressure loss of filter media directly depends on the amount of dust remaining on the filter surface after cleaning. The pressure loss of PTFE film is much smaller than that of surface area dust. The recoil time of the traditional filter media is about 10min, while the recoil time of the PTFE membrane filter is completed within seconds, and the recoil pressure is low. The removal characteristics of the thin film superior, make every recoil can achieve completely clear deposition on the surface of the dust filter does not cause blockage, will not change the porosity and density, so every time after the recoil can immediately resume normal flow, always make filter in low pressure loss condition.Simple Operating High Temperature Resistance Type Gas Box Furnace
(4) long life and low running cost
PTFE film is a kind of soft fiber good toughness, and increase the intensity of the composite material together, the film filter has enough mechanical strength, and excellent ash removal, low recoil frequency and cleaning intensity and low loss, greatly prolongs the service life of the filter, but also reduces the cost.Vacuum Rapid Quenching Rapid Solidification Furnace
The membrane filter material can not block, the number of replacement and the number of cleaning are greatly reduced, thereby reducing the maintenance workload and reducing the maintenance cost. In addition, because of the superior ash cleaning performance, the low pressure loss time continuous operation, not only improves the filtering speed, reduces the amount of filter material, but also reduces the operation power consumption.
(5) wide range of application
The teflon film has high temperature resistance, corrosion resistance, water repellency and other properties, the PTFE film filter can be used in high temperature, high humidity, high corrosion condition, so the filter can be used for high temperature dust filter in industries such as cement, dust filter can also use corrosive gases produced in the chemical industry.
