Abstract
The invention discloses a teflon-wrapped electrothermal tube. The tube comprises an electrothermal tube which is intertwined and wrapped with a teflon dispersion resin film. The teflon dispersion resin film is a modified teflon material. Temperature tolerance of the teflon dispersion resin film is 260-350 DEG C. The teflon electrothermal tube has high temperature resistance and corrosion resistance, is convenient to machine, has uniform surface thickness and has good thermal conductivity. The resin film clings closely to the electrothermal tube.
Description
Technical field
The invention belongs to rapidoprint field, particularly a kind of teflon-coated electrothermal tube.
Background technology
Polytetrafluoroethylene (PTFE) be molecular backbone all by the macromolecular compound that fluorine atom is coated because C-F key has high dissociation energy, the advantage such as allow it have excellent corrosion-resistant, high and low temperature resistance and serviceability temperature scope is wide.These advantages allow with polyflon make product be widely used in various severe corrosive, under the environment of high temperature or low temperature.
At present, the structure of electrical bar is all much exposed on the market, without any outer processing, is secondly teflon tube on the cover of electrical bar surface.There is following shortcoming in this mode: one, because polytetrafluoroethylene internal diameter is unstable, in the process that cover is entered after pullling, easily cause polytetrafluoroethylene pipe explosion, and polytetrafluoroethylene inside pipe wall is not be close to electrical bar.Its two, the wall thickness of teflon tube is generally >=0.75mm, there is heat conduction unfavourable defect.Its three, due to polytetrafluoroethylene itself have special can limitation, although can heatproof below 260 DEG C, during practical application, but can not be applied on the detection field higher than 260 DEG C.
Summary of the invention
In view of the above problems, the object of the present invention is to provide a kind of high temperature resistant, corrosion-resistant, easy to process and be close to, and the polytetrafluoroethylene electrothermal tube that all even thermal conductivity of surface thickness is good.
For achieving the above object, the invention provides a kind of teflon-coated electrothermal tube, comprise electrothermal tube, it is characterized in that, described electrothermal tube is wound around and is enclosed with polytetrafluoro dispersion resin film; Polytetrafluoro dispersion resin film is the polytetrafluoroethylmaterial material carrying out modification; The temperature tolerance of polytetrafluoro dispersion resin film is 260 DEG C-350 DEG C.Thus, not adopt teflon tube to be enclosed within its surface on electrothermal tube surface, but adopt the winding of polytetrafluoro dispersion resin film to be wrapped in electrothermal tube surface.Not only polytetrafluoro dispersion resin film can be close to the surface of electrothermal tube, and the course of processing is also easily simple and easy.In addition, polytetrafluoro dispersion resin film is the polytetrafluoroethylmaterial material carrying out modification, improves the temperature tolerance of material, can under the environment of 320 DEG C Long-Time Service, maximum temperature can reach 350 DEG C.
In some embodiments, under polytetrafluoro dispersion resin film can be applicable to the environment of 320 DEG C for a long time.
In some embodiments, polytetrafluoro dispersion resin film thickness is 0.1-0.11mm, be wound around the teflon tube being wrapped in Thickness Ratio routine on electrothermal tube thin >=0.64mm.。Thus, above-mentioned thickness difference between the two, realizes the effect that thermal conductivity improves greatly.
The invention has the beneficial effects as follows and have high temperature resistant, corrosion-resistant, easy to process and be close to, and the effect that all even thermal conductivity of surface thickness is good.
Embodiment
Below invention is described in further detail.
A kind of teflon-coated electrothermal tube, comprises electrothermal tube.Described electrothermal tube is wound around and is enclosed with polytetrafluoro dispersion resin film.Polytetrafluoro dispersion resin film is the polytetrafluoroethylmaterial material carrying out modification.The temperature tolerance of polytetrafluoro dispersion resin film is 260 DEG C-350 DEG C.Not adopt teflon tube to be enclosed within its surface on electrothermal tube surface, but adopt the winding of polytetrafluoro dispersion resin film to be wrapped in electrothermal tube surface.Not only polytetrafluoro dispersion resin film can be close to the surface of electrothermal tube, and the course of processing is also easily simple and easy.In addition, polytetrafluoro dispersion resin film is the polytetrafluoroethylmaterial material carrying out modification, improves the temperature tolerance of material, can under the environment of 320 DEG C Long-Time Service, maximum temperature can reach 350 DEG C.Under polytetrafluoro dispersion resin film can be applicable to the environment of 320 DEG C for a long time.Polytetrafluoro dispersion resin film thickness is 0.1-0.11mm, be wound around the teflon tube being wrapped in Thickness Ratio routine on electrothermal tube thin >=0.64mm., above-mentioned thickness difference between the two, realizes the effect that thermal conductivity improves greatly.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to the protection range of invention.
