Description

A method for the placement of an antibacterial layer on shaped surfaces of products which come into public, repeated contact with the human body

The subject of the invention is a method of placement of an antibacterial layer on shaped surfaces of products which come into public, repeated contact with the human body, to be used to cover with antibacterial foil such products as stair railings, handrails in public transit vehicles, door handles, school and hospital equipment and other elements which are constantly being touched by any number of persons.

Antibacterial protection, in particular in the times of mass migrations and movement of people, both between distant facilities and in the nearest vicinity, as well as the use of public facilities, such as banks, schools, offices, hospital and public transit forces the users into contact with elements of equipment of such facilities, such as stair railings, door handles, handrails and others. Bacteria remain on the surface of these elements, left by a user, and then transfer onto another user. This may result in falling ill, in the spread of diseases, and in special cases in an epidemic.

To protect against the transfer of bacteria through the touching of public items they were manufactured with copper, which has special antimicrobial properties. These products are very expensive to manufacture, and moreover oxidise after a short time, and the tarnish layer causes it to lose aesthetic properties and reduce antimicrobial properties.

The goal of this invention is the construction of any products with antimicrobial properties by covering them with foil, containing nickel, mainly used to prevent oxidation, and zinc allowing the adoption of an appropriate colour of the foil.

The essence of the invention, which is a method of placement of an antibacterial layer on shaped surfaces of products which come into public, repeated contact with the human body consists of the product, which is a shaped element or a flat surface, being covered with a covering layer with a thickness of at least 0.2 mm, which is an alloy composed of copper in an amount of 60-90%, advantageously 75%, and additives in an amount of 10^0%.

It is advantageous when the covering layer is a foil.

It is also advantageous when the covering layer is a deposit.

It is also advantageous when the covering layer is a cylindrical product in the form of seamless tubes.

It is advantageous when the foil is stabilised on the product.

It is advantageous when the additive is nickel in an amount of 9-20%, advantageously 14%. It is advantageous when the additive is zinc in an amount of 9-20%, advantageously 14%.

It is advantageous when the additive is zinc in an amount of 9-20%, advantageously 14% and nickel in an amount of 9-20%, advantageously 14%.

It is also advantageous when the foil on a shaped element is stabilised by welding the edges of the foil to the product.

It is advantageous when the foil on shaped element is stabilised by gluing.

It is advantageous when the foil on shaped element is stabilised by welding.

It is advantageous when the foil on shaped element is stabilised by brazing.

It is advantageous when the foil is stabilised by entering the edges of the foil into a gap, and fixing the edges, advantageously with an expanding insert.

It is especially advantageous when the material for the creation of a deposit with a thickness of 0.2 - 0.5 mm, advantageously 0.5 mm is a powder, consisting of a mixture of copper with the grain size of 0.05 - 0.8 mm in an amount of 60-90%, advantageously 75%, and additives in an amount of 10-40%, advantageously 25%, whereas such a placed layer undergoes a finish treatment. It is advantageous when the additive is nickel in an amount of 9-20%, advantageously 14%.

It is also advantageous when the additive is zinc in an amount of 9-20%, advantageously 14%.

It is also advantageous when the additive is zinc in an amount of 9-20%, advantageously 14% and nickel in an amount of 9-20%, advantageously 14%.

Additionally it is advantageous, when the deposit is placed with flame deposition with an oxyacetylene torch.

Moreover it is advantageous when the deposit is placed with covered arc welding.

Additionally it is advantageous, when the deposit is placed with arc welding with a covered electrode. .

It is advantageous, when the deposit is deposited with plasma deposition.

Also it is advantageous, when the treatment finish of the top layer of he deposit is conducted by machining.

Furthermore it is advantageous, when the treatment finish of the top layer of the deposit is conducted by grinding. Moreover it is advantageous, when the treatment finish of the top layer of the deposit is conducted by polishing.

It is also advantageous, when the treatment finish of the top layer of the deposit is conducted by surface forming processes.

It is especially advantageous when a pipe is placed on a shaped element after an initial heating and plasticisation of the pipe.

The use of the solution presented in the invention enables the following technical and utility effects:

- construction of products which come into public, repeated contact with the human body, such as stair railings, entrance handrails in public transit vehicles, door handles, hospital furniture and other with an external antibacterial layer,

- increase of hygiene when coming into contact with products covered with foil in accordance with the invention,
