Abstract
The electrolyte consists of chlorides of Cr, Al, Ni and Mo, ammonium chloride, ferric chloride, sodium citrate, etc. When the electrolyte is used, alloy film as thermal film is formed in the cathode through reduction. The thermal film thus formed has high electrothermal efficiency, low cost, high performance, high safety and other advantages.
Description
Technical field involved in the present invention is: electrochemical redox reaction, particularly a kind of extraordinary electrolytic solution that uses in electrothermal film of electromolding alloy making processes.
Galvanoplastics development has had the time of four more than ten years into so far, but, it is in the actual procedure that really is applied to industry and scientific research, be only limited in the use of single element metallic substance, no foundation is looked in electroforming to complex element so far, and general effect is when using galvanoplastics: a, improve surfaceness and carry out decoration function, b, improve the wear-resisting effect on surface; Duplicating of c, part model.And adopt field that galvanoplastics is applied to Electric radiant Heating Film beyond example still.Essential substance in carrying out the electrothermal film of electromolding alloy process-electrothermal film of electromolding alloy electrolytic solution be the link of a particularly important.
The electrolytic solution that the object of the present invention is to provide a kind of electrothermal film of electromolding alloy to use, under the effect of this electrolytic solution, cooperation through galvanoplastics, the character of the Electric radiant Heating Film that negative electrode (being component models) is restored is the metallic membrane of golden composition of isozygotying, thereby thoroughly changed the defective of metal current electrothermal tube and spary coating type Electric radiant Heating Film, improved electrothermal efficiency greatly and avoided that original electrical heating element is expensive, lower performance, the dangerous and shortcoming of factor such as effect in short-term.
The object of the present invention is achieved like this: the electrolytic solution that a kind of electrothermal film of electromolding alloy is used is characterized in that: the electrolytic solution component and the content of low density power (being the electrical heating element of unit surface power density smaller or equal to 5W) are (by weight percentage):

Concrete preparation and using method: 1, at first determine to select for use which kind of electrolytic solution according to the use occasion difference of electrical heating element; 2, the kind of determining electrolytic solution is prepared by following program afterwards: a: take a sample respectively under the help of electronic balance with the container ware of independent beaker or nonmetal corrosion-resistant cleaning and weigh; B: the order of pouring the aqueous solution into is: chromium chloride → aluminum chloride → nickelous chloride → ammonium chloride → molybdenum chloride → iron protochloride
→ Trisodium Citrate → stirring is treated to dissolve fully → is attached boric acid to adjust agent → PH instrument test as pH value.Annotate: band
Number for having according to circumstances or not having.3, deployed electrolytic solution should filter through 200 purpose silk screens earlier before using, the silk screen material requires to be corrosion resistant non-metallic material, its effect is: filter out the solid particulate in the electrolytic solution, in order to avoid the generation of coarse crystal grain appears in the time deposition of the reaction in cathode reduction process.4, use in the process of this electrolytic solution and should use the method for machinery or pneumatic blending to be cooperated, reason is: this solution proportion is bigger, easily produces precipitation and impact effect.When using, these two kinds of methods to note: stir up and down as long as solution is produced, and allow the existing generation of acutely stirring anything but, otherwise ununiformity and the slow phenomenon of sedimentation velocity will occur depositing.
This electrolytic solution should be avoided the influence of environment dust and operates in the temperature range of regulation in use and preservation process.
