Abstract
The invention discloses an antimicrobial enamel inner container of a water heater. An antimicrobial enamel layer is adhered to the surface layer of the inner container of the water heater and successively comprises an enamel antimicrobial layer (1), an adhering layer (2) and a steel plate layer (3) from inside to outside, wherein the thickness of the enamel antimicrobial layer is 0.3-0.5mm; the thickness of the adhering layer is 0.02-0.03mm; and the thickness of the steel plate layer is 1.5-2.5mm. The antimicrobial nano silver ion emulsion is evenly mixed with glaze slurry, and then the mixture is coated on the surface of the steel plate layer of the inner container of the water heater with a wet enamel dipping or antimicrobial enamel spraying method; an antimicrobial enamel layer adhered to the surface of the inner container is formed by virtue of baking; and under the existing technical condition, no additional equipment is required, and the existing enamel technology does not need to be changed. The antimicrobial enamel inner container is simple and practicable. Meanwhile, on the premise of solving the problem that the existing water heater can not be thoroughly drained and cleaned, the water quality is purified, and microorganisms in the water can be prevented from generating, and the antimicrobial enamel inner container is easier for wide popularization.
Description
Technical field
The present invention relates to a kind of antibacterial enamel water heater and use and manufacture method, specifically, the present invention relates to proportioning and the mixed method of antibacterial enamel, and make the method for antibacterial enamel water heater liner.
Background technology
Water heater is to store water by inner bag; and finish water by heating element heater and heat, directly take the interior hot water of water heater liner during use also and cold water mix, the function of release hot water when obtaining length; and inner bag is because main body is steel plate; contact with water for a long time, if there is not protective layer, very fast generation corrosion phenomenon then; have a strong impact on the service life of water heater; the enamel protective layer then arises at the historic moment, and glaze is through high-temperature firing, has enough resistance to compressions, intensity, premium properties such as corrosion-resistant, nontoxic.
At present; its inner bag of the water heater of selling on the market is mainly stainless steel inner container; enamel inner container; its enamel inner container is the storage-type electric water heater first-selection; overwhelming majority's water heater manufacturer all uses enamel inner container; and because water heater again in the process of discharge water; there is the slough that can't obtain exchanging for a long time; do not clean inner bag if do not carry out thorough emptying; water that then should the zone can be deposited in the water heater liner for a long time; because the water quality difference of all parts of the country can produce a large amount of incrustation scales in the long-term use again, simultaneously owing to the protected mode of most manufacturers to inner bag; adopt sacrificial protection; just protect inner bag with the magnesium rod, also have a large amount of oxides to produce in long-term the use, these species precipitate are in the inner bag bottom; for a long time possible polluted water; from a large amount of market dispositions, use the inner bag that cleaned in 1～2 year, during emptying first; the ubiquity of inner bag bottom water muddy situation in various degree, this present situation make us producing worried to the health index of water.
Current, silver ion can become well known fact by sterilization, rise as far back as the thirties in 20th century, west man and domestic powder or the solution that has begun to use silver prevent and eliminate various bacteriums to cause disease, a large amount of medical devices also obtains promoting, and Ag+ can attract the sulfydryl on the protease in the bacterial body (SH), to combine with it rapidly consumingly, make the protease loss of activity, cause bacterium death.After bacterium was killed by Ag+, Ag+ contacted with other bacterium colony more again by dissociating out in the bacterium corpse, carries out said process again and again, and this also is the persistent reason of silver-colored sterilization.
Summary of the invention
The objective of the invention is to adopt the mode of adding antimicrobial nano silver ion prescription in conjunction with existing water heater liner enamel technology, directly adopt existing enamel technology, simple, and improve the present situation that may produce unclean microorganism in the present water quality, provide
