The patent No. is the patent of 200410024542.9, discloses a kind of manufacture method of composite fibre Nomex, is the compound spiked felt made of a kind of glass fibre and polypropylene fibre, this technique is too simple, and fibers mixture is uneven, does not have base cloth layer, loosely organized brute force is on the low side, and filtering accuracy is low.
The patent No. is the patent of 201220399886.8, discloses a kind of composite needled filter felt, is to be equipped with P84 fibrous face layer to improve filtering accuracy on the surface of PTFE Nomex, but causes the inner laying dust of Nomex after Long-Time Service, causes dust pelletizing system resistance to raise; PTFE and P84 material price costliness seriously limits the application of product simultaneously.
The patent No. is the patent of 201020659486.7, disclose glass fibre and polyimide fiber composite filter needled felt, it is the two-side needled polyimide fiber at fiberglass-based cloth, the trilobal cross structure utilizing P84 special is to retain dust, also the inner laying dust of Nomex is there is after Long-Time Service, the phenomenon causing dust pelletizing system resistance to raise, affects the normal work of dust pelletizing system.
The patent No. is the patent of 201020659434.X, disclose glass fibre and aramid fiber composite filter needled felt, it is the two-side needled aramid fiber at fiberglass-based 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 heatproof 220 DEG C after Long-Time Service, the phenomenon causing dust pelletizing system resistance to raise, affects the normal work of dust pelletizing system.
Summary of the invention
The problem that the physical and chemical index such as heat-resisting quantity, chemical resistance, structural stability that the filtrate that the object of the invention is to make for existing technology exists is undesirable, by the Optimal improvements of technique, provide 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.
Realize the preparation method of the high-performance glass composite felt filtrate of the object of the invention, comprise 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, glass compound spiked felt is made;
(3) at glass compound spiked felt dust-collecting face overlay film or coating polytetrafluoroethylene (PTFE).
High-performance glass base cloth described in step (1), adopts superfine glass fiber yarn to become superfine glass fiber woven fabric respectively as warp thread with weft weaving, then makes through PTFE impregnation process.
Also comprise between step (2) and step (3): by overall for glass compound spiked felt through PTFE emulsion impregnation process.
According to the filtrate that above-mentioned preparation method makes, described filtrate comprises five-layer structure, comprises polyfluortetraethylefilm film coated or coating, superfine glass fiber composite fibre surface layer, middle dawn glass composite fibre surface layer, high-performance glass base cloth layer and middle dawn glass composite fibre surface layer successively from dust-collecting face.
Adopt the beneficial effect of preparation method of the present invention:
(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 is overall 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 process rear surface to carry out overlay film or coating processing, filtering accuracy is high;
(4) filter material surface is smooth, filtration deashing is good, and after Long-Time Service, SR raises extremely slow, and service life effectively extends.
