The aluminium alloy tank shell
Technical field
The utility model relates to a kind of aluminium alloy tank shell.
Background technology
In the water tank that uses now, water tank internal layer situation such as tend to occur getting rusty because of long-term use influences the quality of the interior water of water tank; And the water tank long term exposure that has in the sun; After being exposed to the sun for a long time, the scalding very that the water in the water tank can become influences the quality of water equally; At some traditional water tanks is main with made of iron and plastics mostly; Water tank made of iron has been grown later the inside and inevitably can get rusty service time, the water tank of plastics is long-time use or be exposed to the sun in the sun after can decomposite in the water of noxious material in the water tank, influence people's health; And the water tank made of iron that has or some water vats all can feel the heaviness of comparison when installing, and bring many constant for people's installation.
The utility model content
The technical problem that the utility model will solve is: in order to overcome the above problems, a kind of aluminium alloy tank shell is provided.
The utility model solves the technical scheme that its technical problem adopted: a kind of aluminium alloy tank shell, comprise tank body, and be coated with matcoveredn on the described tank body inner surface, be coated with the reflective insulation layer on the described tank body outer surface.
Described protective layer is the horniness anode oxide film after the hard anode treatment.
Described reflective insulation layer is a reflecting heat-insulating metal coating.
The beneficial effect of the utility model is: solve the problem that is run in the background technology; On the inner surface of tank body, be coated with protective layer; Can play preventing that effectively housing from contacting with the direct of running water, thereby avoid water tank to receive oxidation and generate scale, thereby prolong the service life of water tank; Be provided with the reflective insulation layer in the outside of tank body, can avoid when water tank is exposed to the sun, influencing temperature, the quality of water in the water tank under the sun, when adopting aluminium alloy can alleviate the weight of water tank, carrying that is convenient for people to and installation as the water tank material.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 be in the utility model the aluminium alloy tank shell generalized section;
Wherein: 1. tank body, 2. protective layer, 3. reflective insulation layer.
The specific embodiment
Combine accompanying drawing that the utility model is further described now.The sketch map that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.
Aluminium alloy tank shell as shown in Figure 1 comprises tank body 1, is coated with matcoveredn 2 on described tank body 1 inner surface, is coated with reflective insulation layer 3 on described tank body 1 outer surface.
On tank body 1 inner surface, one deck horniness anode oxide film is set; One deck reflecting heat-insulating metal coating is set on the outer surface of tank body 1; Tank body 1 is to have aluminum alloy materials to process, and when this water tank is used for depositing running water, exists the water of the inside can not worry being exposed to the sun of the sun so; Do not worry the situation of getting rusty of tank body 1 yet, durable for a long time.
Hard anodizing is meant through executing anode current outward and makes the metal surface form a kind of material protection technology of oxide-film.Claim surperficial anodic oxidation again.After metal material or goods were handled through surface anodization, its corrosion resistance, hardness, wearability, insulating properties, hear resistance etc. all were improved largely.
Implementing the maximum metal material of anodization is aluminium, and anodizing of aluminium is generally carried out in acidic electrolysis bath, is anode with aluminium.In electrolytic process, the anion of oxygen and aluminium effect produce oxide-film.This film is fine and closely woven inadequately when initial formation, though certain resistance is arranged, the negative oxygen ion in the electrolyte still can arrive the aluminium surface and continue to form oxide-film.Along with film thickness increases, resistance also becomes greatly, thereby Faradaic current diminishes.At this moment, the outer oxide film generation chemolysis that contacts with electrolyte.The speed that forms oxide when aluminium surface is during gradually with the velocity balance of chemolysis, and this oxide-film just can reach the maximum ga(u)ge under this electrolytic parameter.The outer porous of anodizing of aluminium film, absorbing dye and coloring matter easily, thereby can dye improve that it is ornamental.Oxide-film after hot water, high-temperature vapor or nickel salt sealing are handled, can also further improve its corrosion resistance and wearability again.Except that aluminium, the metal that adopts surface anodization to handle in the industry also has magnesium alloy, copper and copper alloy, zinc and kirsite, steel, cadmium, tantalum, zirconium etc.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
