The membrane-coated filter material has excellent performance. Its filtration method is membrane surface filtration, which can intercept 100% of the filtered material.
PTFE filter membrane is called an indispensable new material for dust and material collection and precision filtration. Its advantages are as follows.
(1) High surface filtration efficiency. Usually industrial filter materials are depth filtration, which relies on the establishment of a dust layer on the surface of the filter material to achieve effective filtration.
It takes a long time to establish effective filtration (about 10% of the entire filter layer), large resistance, low efficiency, incomplete interception, large loss, high filtration and backflush pressure, frequent cleaning, high energy consumption, and long service life Not long, the equipment occupies a large area.
(2) Long-life coated filter material can exert its superior characteristics regardless of the life-span cleaning mechanism. It is a filter material designed to fully exert its high-efficiency filtration function in the dust collector, so it is low in cost.
The coated filter material is a strong and soft fiber structure, which is compounded with a strong base material, so it has sufficient mechanical strength, coupled with excellent dedusting properties, it reduces the dust cleaning intensity. With low and stable pressure loss, it can be used for a long time, extending the life of the filter bag.
(3) Easy to clean. The operating pressure loss of any kind of filter material directly depends on the amount of dust that remains or stays on or under the surface of the filter material after cleaning. The cleaning time of the coated filter cloth only takes a few seconds. , has very superior dust cleaning characteristics. Every time it is cleaned, the dust layer can be completely removed. There will be no clogging inside the filter material, no change in void ratio and mass density, and it can often maintain low pressure loss operation.
(4) Low-pressure, high-flux continuous operation. Once the traditional depth filtration filter material is put into use, dust penetrates, a primary dust layer is established, and the air permeability drops rapidly.
During filtration, the dust accumulated inside causes clogging, thereby increasing the resistance of the dust equipment.
The micropores and non-stickiness of the membrane-coated filter material make the dust penetration rate close to zero. It provides the highest filtration efficiency after being put into use. When the filtered matter deposited on the surface of the PTFE filter membrane filter material reaches a certain When it is thicker, it will automatically fall off and be easy to clean, so that the filtration pressure is always maintained at a very low level, the air flow is always maintained at a high level, and it can work continuously.
