Abstract
The present invention relates to efficient energy-saving electrothermal film and a manufacture method thereof. The electriothermal film is composed of the following components (by weight percentage): 15 to 40 percent of graphite, 30 to 75 percent of carbonic acid adhesive, 5 to 15 percent of glass powder and 5 to 15 percent of quartz powder. In the manufacture method of the present invention, after a mixture of the electrothermal film is coated on the surface of an insulator, the insulator is roasted for 10 to 30 minutes at the temperature ranging from 200 to 500 DEG C, silver pulp is coated on the peripheries of the insulator and the electric heating film, and furthermore, the silver pulp is also covered on one part of the upper surface of the electrothermal film; the electrothermal film and the insulator which are coating with conduction bands are heated again for 1 to 4 hours at the temperature ranging from 100 to 230 DEG C. 30 percent of power can be saved by the electrothermal film, the conduction band position is non-oxidizable, the service life reaches twelve thousand hours, and the rate of finished products reaches 95 percent.
Description
Technical field: the invention belongs to membrane type electricity heating product and manufacturing technology thereof.
Background technology: the core component Electric radiant Heating Film in the existing membrane type electric heating device exists the heat efficiency low, the easy oxidation in the junction of Electric radiant Heating Film and conductive strips, and shortcomings such as bulk life time weak point, the product cost rate that its manufacture method obtains is low.
Summary of the invention: the objective of the invention is to develop a kind of energy-efficient membrane type electric heating device, this electric heating device should have the non-oxidizing characteristics in junction of heat efficiency height, life-span length, Electric radiant Heating Film and conductive strips.Provide its manufacture method simultaneously, the finished product rate height that this method is made.The present invention is made up of insulator 2, Electric radiant Heating Film 1, conductive strips 3, Electric radiant Heating Film 1 is solidificated on the surface of insulator 2, conductive strips 3 cover respectively and are solidificated on 1 liang of outer end of Electric radiant Heating Film and the insulator 2, and conductive strips 3 cover the top outward flange 1-1 place that is solidificated in Electric radiant Heating Film 1 again.Electric radiant Heating Film 1 is made up of graphite powder, carbonic acid glue, glass dust, silica flour, and they respectively account for following ratio by weight percentage: graphite powder 15～40, carbonic acid glue 30～75, glass dust 5～15, silica flour 5～15.Manufacture method of the present invention is: get the graphite powder 15～40 that percentage by weight is respectively following ratio, carbonic acid glue 30～75, glass dust 5～15, silica flour 5～15 mixes, above-mentioned compound is coated with on the surface that is imprinted on insulator 2 with the planographic machine, deliver to then in the kiln and roasted 10～30 minutes, temperature is controlled at 200 ℃～500 ℃, after the taking-up silver slurry is brushed respectively on insulator 2 and the contacted both sides of compo film, allow silver slurry band promptly contact with insulator, also the outer end with the compo film contacts, and silver slurry band also covers outward flange 1-1 place above the compound film.The insulator 2 that scribbles silver slurry band and compo film was heated 1～4 hour again, and temperature is controlled at 100 ℃～230 ℃.Electric radiant Heating Film of the present invention is compared with existing Electric radiant Heating Film can economize on electricity about 30%, Electric radiant Heating Film and conductive strips not oxidation of junction, and working life can reach 120,000 hours, and rate of finished products can reach more than 95%, and course of processing barbecue temperature does not need high temperature.
Description of drawings: Fig. 1 is an overall structure schematic diagram of the present invention.
Embodiment one: present embodiment is made up of insulator 2, Electric radiant Heating Film 1, conductive strips 3, Electric radiant Heating Film 1 is solidificated on the surface of insulator 2, conductive strips 3 cover respectively and are solidificated on 1 liang of outer end of Electric radiant Heating Film and the insulator 2, and conductive strips 3 cover the top outward flange 1-1 place that is solidificated in Electric radiant Heating Film 1 again.Electric radiant Heating Film 1 is made up of graphite powder, carbonic acid glue, glass dust, silica flour, and they respectively account for following ratio by weight percentage: graphite powder 30, carbonic acid glue 50, glass dust 10, silica flour 10.
Embodiment two: present embodiment is got percentage by weight and is respectively: graphite powder 30, carbonic acid glue 50, glass dust 10, silica flour 10 mix, compo is imprinted on the surface of insulator 2 with the planographic machine, deliver to then in the kiln and roasted 25 minutes, temperature is controlled at about 300 ℃.After the taking-up silver slurry is brushed respectively on insulator 2 and the contacted both sides of compo film, allowed silver slurry band both contact with insulator 2, also the outer end with the compo film contacts, and silver is starched band and also covered outward flange 1-1 place above the compo film.Conductive strips 3 and Electric radiant Heating Film 1 and guaranteed the conductive strips not oxidation of synapsis that is connected with Electric radiant Heating Film with this syndeton of insulator 2 and technical process thereof.The insulator that scribbles silver slurry band and compo film was heated 3 hours again, and temperature is controlled at about 180 ℃.
