Description
Technical field
The present invention relates to a kind of curing and hot compound device, especially relate to a kind of polytetrafluoroethylfilm film hardening and heat composite apparatus of being used for.
Background technology
Microporous teflon membran serviceability temperature scope wide (200 ℃～260 ℃) by biaxial tension, coefficient of friction is little, chemical resistance is good, therefore extensively be used as filter medium in fields such as chemical industry, the energy, environmental protection, electronics, its microporous morphosis feature and strong-hydrophobicity make it in a large number as the material of main part of Waterproof Breathable functional fabric and medical protective garment, have therefore obtained extensive application in a plurality of fields.
Solidifying in the process of microporous teflon membran is a key link, and it directly has influence on the dimensional stability and the serviceability of film.Described a kind of contactless solidification device in the patent 99244710.0, this solidification device is made up of many strip heaters, and its width is 50 millimeter, and the thermal treatment zone is the 500-2000 millimeter.Distance between polytetrafluoroethylene film and the strip heater is the 10-15 millimeter, controls hardening time by relative position and the quantity that changes heater under the certain situation of the speed of a motor vehicle.This solidification device is easy to use, flexible, but also have certain defective: polytetrafluoroethylene film in solidification process by both sides chain clamping, because under the effect of heat, very easily form in the middle of the film and suspend, and finally cause the inhomogeneous of film, be both sides when having solidified fully, the centre is still uncured good.Another shortcoming be consume energy bigger.This solidification device only can be used the curing of simple polytetrafluoroethylene film, can not be applicable to patent (application number 03100830.5, stretch the jointly preparation method of composite membrane of polyurethane-polytetrafluoroethylene (PTFE)) composite membrane that stretches jointly of the polyurethane-polytetrafluoroethylene (PTFE) in, reason is the polyurethane component degradation with aging in this solidification device easily in the composite membrane, even combustion phenomena occurs.
When microporous teflon membran is used for the coated filter material of high-temperature dust removal bag, must be combined with each other with backing materials such as non-weaving cloths.Present compound adhesive means that adopt more, but select comparatively difficulty of megathermal adhesive, therefore do not have the emphasis that the hot complex method of glue is development, it mainly is to utilize high temperature to make polytetrafluoroethylene film be in the semi-molten state, and it is bonding that film and backing material are taken place.Mostly present hot equipment complex is to adopt a steel rider and a rubber rollers, and by the conduction oil or the electrothermal tube heating of steel rider inside, but surface temperature generally is lower than 250 ℃.Treat that the compound material of heat passes in the middle of steel rider and rubber rollers, the rubber rollers pressurization, it is compound that material is carried out heat.Therefore this covering device only can make the lower backing material generation partial meltings of fusing point such as resembling polypropylene, polyethylene, terylene, only limits to the compound of such low melting material and polytetrafluoroethylene film, and the material after compound can only be used for the low temperature dust settling pocket.Backing material for high-temperature dust removal bag usefulness mostly is the Nomex that short fibers such as glass fibre, polyimides, polytetrafluoroethylene (PTFE), aramid fiber, polyphenylene sulfide are made, temperature below 250 ℃ promptly can not make the backing material partial melting, can not make the polytetrafluoroethylene film partial melting, simultaneously lack the high temperature modification adhesive at present again, so the high-temperature dust removal bag is with the difficulty that is processed into maximum of composite filtering material.
Summary of the invention
The purpose of this invention is to provide a kind of polytetrafluoroethylfilm film hardening and heat composite apparatus of being used for.The surface temperature of the contact hot-rolling in this device can be up to 450 ℃, can be used for stretch the jointly curing of composite membrane of polytetrafluoroethylene film, polyurethane-polytetrafluoroethylene (PTFE); The temperature resistant rubber roller is set above hot-rolling, then can be used for the high-temperature dust removal bag and use the hot compound of coated filter material.
The technical solution used in the present invention is that it comprises:
