BODY OF A SANITARY FITTING HAVING AN ANTI-CORROSION LAYER AND A METHOD FOR MANUFACTURING SUCH A BODY

Abstract

A method for manufacturing a body for a sanitary fitting that involves the following steps: provision of the body, wherein the body contains at least partially a zinc alloy and has at least one area for guiding a liquid; and coating the at least one area using an anti-corrosion coating, wherein the anti-corrosion coating is at least partially formed of a polymeric material.

Claims

1. A method for manufacturing a body (1) for a sanitary fitting (2), at least comprising the steps listed below: a) provision of the body (1), wherein the body (1) consists at least partially of a zinc alloy and has at least one area (3) for guiding a liquid; and b) coating the at least one area (3) using an anti-corrosion coating (4), wherein the anti-corrosion coating (4) is at least partially formed of a polymeric material.

2. The method according to claim 1, wherein the zinc alloy contains zinc at a mass fraction greater than 80%.

3. The method according to claim 1, wherein the body (1) is manufactured by a zinc die-casting process before step a) is performed.

4. The method according to claim 1, wherein the coating of the at least one area (3) is performed in step b) without any prior treatment of the at least one area (3).

5. The method according to claim 1, wherein the coating in step b) is applied by painting, immersing or spinning.

6. The method according to claim 1, wherein the corrosion protection layer (3) in step b) is formed having a layer thickness of 50 μm to 2 mm.

7. The method according to claim 1, wherein after step b), the anti-corrosion layer (4) is solidified at a room temperature in step c).

8. The method according to any one of , wherein, after step b), heat is used to solidify the corrosion protection layer (4) in step c).

9. The method according to claim 1, wherein the polymeric material is at least in part polytetrafluoroethylene, polypropylene or polystyrene.

10. A body (1) for a sanitary fitting (2), wherein the body (1) consists at least partially of a zinc alloy and has at least one area (3) for guiding a liquid, and wherein the at least one area (3) is coated with a corrosion protection layer (4) which consists at least partially of a polymeric material.

Description

[0026] The invention and the technical environment are explained in more detail below with reference to the figures. It should be noted that the figures show a particularly preferred embodiment variant of the invention, but the invention is not limited thereto. The same reference signs are used for the same components in the figures. Schematically:

[0027] FIG. 1 shows a lateral view of a sanitary fitting; and

[0028] FIG. 2 shows a perspective view of a body of a sanitary fitting.

[0029] FIG. 1 shows a side view of the sanitary fitting 2. The sanitary fitting 2 has a body 1 having an outlet 6 with an outlet opening 5. The body 1 is attached to a support 9, which in this case may be a wash basin. A mixing cartridge 7 is arranged in the body 1, to which cold water and hot water can be routed separately via supply lines 8. The mixing cartridge 7 can be used to mix the cold water and the hot water to form a mixed water having a desired mixed-water temperature. The mixing cartridge 7 is connected to the outlet opening 5 in a fluid conveying manner, for the mixed water to be discharged via the outlet opening 5. In so doing, the mixed water contacts an area 3 of the body 1 shown in FIG. 2. Furthermore, a lever 10 can be used to actuate the mixing cartridge 7, which lever can be used to adjust the mixed-water temperature and a discharge quantity of the mixed water via the outlet opening 5.

[0030] FIG. 2 shows a perspective view of the body 1 of the sanitary fitting 2 of FIG. 1. In FIG. 1, the view is through the outlet opening 5 of the outlet 6 towards an area 3 of the body 1, which is used to guide the mixed water. The area 3 of the body 1 is an inner surface of the outlet 6.

[0031] In the manufacture of the body 1, the body 1 was first provided in a step a) and then, in a step b), an anti-corrosion layer 4 was applied to the area 3. The anti-corrosion layer 4 prevents the area 3 from corroding due to contact with the mixed water.

[0032] This invention can at least reduce a use of plastic inserts to prevent contact of the mixed water with the body.
