The patent No. is 200410024542.9 patent, discloses a kind of manufacture method of composite fibre Nomex, is the compound spiked felt of making of a kind of glass fibre and polypropylene fibre, this technique is too simple, and fiber mixes uneven, there is no base cloth layer, loosely organized brute force is on the low side, and filtering accuracy is low.
The patent No. is 201220399886.8 patent, discloses a kind of composite needled filter felt, is to be equipped with P84 fibrous face layer on the surface of PTFE Nomex to improve filtering accuracy, but after long-term use, causes the inner laying dust of Nomex, causes dust pelletizing system resistance to raise; PTFE and P84 material price costliness have seriously limited the application of product simultaneously.
The patent No. is 201020659486.7 patent, glass fibre and polyimide fiber composite filter needled felt are disclosed, it is the two-side needled polyimide fiber at glass fibre base cloth, special trilobal cross structure is held back dust to utilize P84, after long-term use, also there is the inner laying dust of Nomex, the phenomenon that causes dust pelletizing system resistance to raise, affects the normal work of dust pelletizing system.
The patent No. is the patent of 201020659434.X, glass fibre and aramid fiber composite filter needled felt are disclosed, it is the two-side needled aramid fiber at glass fibre base cloth, improve the resistance to chemical corrosion of filtrate, but aramid fiber hydrolytic resistance is slightly poor,, also there is the inner laying dust of Nomex in 220 ℃ of heatproofs after long-term use, the phenomenon that causes dust pelletizing system resistance to raise, affects the normal work of dust pelletizing system.
Summary of the invention
The object of the invention is the undesirable problems of physical and chemical index such as heat-resisting quantity that the filtrate made for existing technology exists, chemical resistance, structural stability, optimization by technique improves, and provides that a kind of temperature tolerance is good, good corrosion resistance, filtering accuracy are high, the glass composite felt filtrate of long service life and preparation method thereof.
The preparation method who realizes the high-performance glass composite felt filtrate of the object of the invention, comprises step:
(1) dawn glass composite fibre in the two-side needled of high-performance glass base cloth, makes middle dawn glass compound spiked felt;
(2) at middle dawn glass compound spiked felt dust-collecting face acupuncture superfine glass fiber composite fibre, make glass compound spiked felt;
(3) at glass compound spiked felt dust-collecting face overlay film or coating polytetrafluoroethylene (PTFE).
The high-performance glass base cloth that step (1) is described, adopts superfine glass fiber yarn to become respectively superfine glass fiber woven fabric with weft weaving as warp thread, then makes through PTFE impregnation process.
Between step (2) and step (3), also comprise: by glass compound spiked felt entirety process PTFE emulsion impregnation process.
The filtrate of making according to above-mentioned preparation method, described filtrate comprises five-layer structure, from dust-collecting face comprise successively polyfluortetraethylefilm film coated or coating, superfine glass fiber composite fibre surface layer, dawn glass composite fibre surface layer, high-performance glass base cloth layer and middle dawn glass composite fibre surface layer.
Adopt preparation method's of the present invention beneficial effect:
(1) adopt high-performance glass base cloth, through PTFE impregnation process, high-strength flatness, corrosion resistance are good;
(2) adopt glass composite fibre surface layer, filtrate entirety is through PTFE emulsion impregnation process in addition, and serviceability temperature is high, anti-oxidant, good corrosion resistance;
(3) adopt superfine fibre surface layer and PTFE emulsion mass-impregnation to process rear surface and carry out overlay film or coating processing, filtering accuracy is high;
(4) filter material surface is smooth, filtration deashing is good, and the rear SR of long-term use raises extremely slow, and effectively extend service life.
