2
Described GY meets knoisphere (2) and is respectively the mixed layer body that the PPS fiber of glass fibre, the 2.5D * 60mm of polyster fibre, the 5D * 60mm of 2.8D * 60mm forms, and grammes per square metre is 100g/m
2
Described base cloth layer (3) is the textle layers body that 5D * 60mm glass fibre forms, and grammes per square metre is 300g/m
2
Described GY adhesion layer (4) is respectively the mixed layer body that the PPS fiber of glass fibre, the 2D * 60mm of polyster fibre, the 5D * 60mm of 2.5D * 60mm forms, and grammes per square metre is 150g/m
2
The utility model technology has following advantage:
1. be applicable to the improvement of high temperature, high humidity, high burn into oiliness flue gas operating mode;
2. be furnished with a certain proportion of water oil-proofing agent of refusing in the PTFE maceration extract, make filtrate have very high hydrophobicity and grease proofness, the dust that touches filtrate can come off very soon, has solved the problem that the oiliness dust hardens and stops up filtrate;
3. after blending, impregnation process, the pliability of filtrate, tensile strength, wearability and decay resistance are significantly improved;
4. adopt the highlighted calendering technique of high temperature to substitute conventional coating technique, mixed the grease proofing filter material surface of refusing the water microporous barrier more smooth, more hydrophobic, more grease proofing, filtering accuracy is higher, reduced the gathering of dust; Make the dust of filtration be easy to remove from the film surface, ash-removal effect is good, the cycle is long, thereby has reduced operating cost the service life of having improved filtrate;
5., take glass fibre, polyster fibre as main base-material, improved the pliability of glass fibre and the resistance to elevated temperatures of polyster fibre after mixing by adding PPS, P84, PTFE fiber, and greatly reduced cost.
