Abstract
The invention discloses an enamel inner container of an antibacterial electric water heater and a manufacturing method of the enamel inner container. The enamel inner container of the antibacterial electric water heater comprises an inner container of the electric water heater. A layer of gradient nano-silver, nano-copper and nano-silver-phosphate antibacterial enamel coating is coated on the inner wall of the inner container of the electric water heater. The improved low-cost enamel inner container of the antibacterial electric water heater, provided by the invention, has good antibacterial performances.
Description
Technical field
The present invention relates to household electrical appliance technical field, relate to a kind of electric heater enamel inner container and manufacturing approach thereof in particular.
Background technology
The kind of the electric heater that uses on the market at present and style are more and more, and function also is not quite similar.And present inner container of electric water heater is different according to material, generally can be divided three classes, and the one, on the plain steel inwall, add the coat of metal or plastic lining resin bed; The 2nd, adopt stainless steel to be welded, the 3rd, on plain steel, apply enamel material and process enamel inner container.Because the existence of chlorion in the water, the resistance to corrosion of preceding two kinds of water heater water courages is limited.Therefore, therefore enamel inner container is used the most extensive because of having advantages such as corrosion resistance and physical life be long at present.
Therefore in the existing technology, enamel inner container all has water storage at water heater water courage median year because water storage is more, often bigger, as the long period need not, form stagnant water, be easy to breed bacteria.Unfavorable to user's health.Therefore be necessary to adopt antibacterial process, suppress the bacteria breed of long-time water storage.And water quality is a great problem of electric heater product technology like " stagnant water is said " of problem such as not using for a long time to cause always, and present still do not have an antimicrobial technology that has technical data to mention the electric heater water storage liner.
Antibacterial enamel is the most promising electric heater water courage antibiotic method, and the most general additive of antibacterial enamel is that the inorganic silver salt of employing is an antiseptic at present, and the addition of silver salt need be more than 2% usually, and this will greatly increase production cost.Be not easy on the inner container of electric water heater of high surface area, use, and influence enamel property.Also having document to mention the employing complex antimicrobials, mainly is organic silver antiseptic and photocatalyst acting in conjunction.Water heater liner is in the environment of a sealing, so photocatalyst can not have sterilizing ability at this.Have document to propose to adopt the multilayer enamel coating, but multilayer enamel needs repeatedly sintering, technology is loaded down with trivial details, and power consumption is big, has also increased production cost.
Summary of the invention
The object of the invention is exactly that a kind of not only manufacturing process that provides for the deficiency that solves prior art is simple, and the antibiotic electric heater enamel inner container with good antibacterial performance.
It is simple that another object of the present invention provides a kind of not only manufacturing process, and have the manufacturing approach of the antibiotic electric heater enamel inner container of good antibacterial performance.
The present invention adopts following technical solution to realize above-mentioned purpose: a kind of antibiotic electric heater enamel inner container; Comprise inner container of electric water heater; It is characterized in that, be coated with one deck gradient distribution Nano Silver, nanometer copper and nanometer silver phosphate antibacterial enamel coating on the said inner container of electric water heater inwall.
As further specifying of such scheme: in said enamel coating, Nano Silver, nanometer copper and nanometer silver orthophosphate powder even dispersion are distributed in the 20-40 μ m of enamel matrix top layer.
Said inner container of electric water heater is the steel inner bag.
A kind of manufacturing approach of antibiotic electric heater enamel inner container is characterized in that, it is with behind the water heater liner welding fabrication, through blasting treatment, applies one deck antibacterial enamel coating at the inner bag inwall; Coating adopts enamel slurry to apply; After 10-30 minute, employing is contained the liquid of the particle diameter of even dispersion distribution at Nano Silver, nanometer copper and the nanometer silver orthophosphate 0.5-2g/L of 20nm-100nm, through 70-100 degree centigrade of baking through stirring; Evenly be sprayed on coating substrate surface; Every square metre sprays 20-200 milliliters, after waiting to dry, burns till enamel in 10-30 minute through 750-910 degree centigrade of baking.
In the preparation process of said Nano Silver, nanometer copper and nanometer silver orthophosphate liquid, add water and PVP 0.01-0.1g/L and increase dispersion effect as dispersant.
In said Nano Silver, nanometer copper and the nanometer silver orthophosphate liquid-liquid, the content of silver is at 0-5.0g/L, and the content of copper is at 0-5.0g/L, and the content of silver orthophosphate is at 0-4.0g/L, and wherein, the content of silver and silver orthophosphate is not zero simultaneously.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
The present invention is employed in the enamel coating, and Nano Silver, nanometer copper and nanometer silver orthophosphate powder even dispersion are distributed in the 20-40 μ m of enamel matrix top layer, play antibacterial action, and production cost is low than mixed uniformly enamel.Have good antibacterial performance through this enamel coating, Chinese People's Anti-Japanese Military and Political College enterobacteria and staphylococcus all reach 90-99%, do not need the twice sintering simultaneously, and production cost reduces greatly, and very little to the performance impact of enamel layer.

Fig. 1 is a structural representation of the present invention.
Description of reference numerals: 1, inner container of electric water heater 2, enamel coating 3, Nano Silver 4, nanometer copper 5, nanometer silver orthophosphate powder.
The specific embodiment
As shown in Figure 1; A kind of antibiotic electric heater enamel inner container of the present invention comprises inner container of electric water heater 1, is coated with one deck gradient distribution Nano Silver, nanometer copper and nanometer silver phosphate antibacterial enamel coating 2 on the inner container of electric water heater inwall; Wherein, inner container of electric water heater 1 is the steel inner bag.In said enamel coating 2, Nano Silver 3, nanometer copper 4 and nanometer silver orthophosphate powder 5 even dispersion are distributed in the 20-40 μ m of enamel matrix top layer, form the rich silver layer in top layer.
In the antibiotic electric heater enamel inner container process of preparation, it is with behind the water heater liner welding fabrication, through blasting treatment, applies one deck antibacterial enamel coating at the inner bag inwall; Coating adopts enamel slurry to apply, and after 10-30 minute, employing is contained the liquid of the particle diameter of even dispersion distribution at Nano Silver, nanometer copper and the nanometer silver orthophosphate 0.5-2g/L of 20nm-100nm through 70-100 degree centigrade of baking; Wherein, in Nano Silver, nanometer copper and the nanometer silver orthophosphate liquid-liquid, the content of silver is at 0-5.0g/L; The content of copper is at 0-5.0g/L; The content of silver orthophosphate is at 0-4.0g/L, and wherein, the content of silver and silver orthophosphate is not zero simultaneously.Add water and PVP 0.01-0.1g/L and increase dispersion effect as dispersant; Through stirring, evenly be sprayed on coating substrate surface, every square metre sprays 20-200 milliliters; After waiting to dry, burnt till enamel in 10-30 minute through 750-910 degree centigrade of baking.
Above-described only is preferred implementation of the present invention, should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
