Anticorrosion and antibacterial treatment method for wrought iron railings

Abstract

The invention discloses an anticorrosion and antibacterial treatment method for iron art railings, which comprises six major steps of pretreatment, phosphating treatment, dust removal treatment, antibacterial treatment, and antiseptic treatment. Silver plating and re-plating treatment can make it have excellent antibacterial performance. In the anti-corrosion treatment step, Interpon 600AM, a subsidiary of AkzoNobel, is used to inhibit bacterial regeneration powder. The minimum antibacterial efficiency is 95% tested by ISO 22196‑2011 , which can make the treated wrought iron railings have excellent anti-corrosion performance; the whole treatment process is simple, easy to realize, and has a high degree of industrialization in production.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to an anticorrosion and antibacterial treatment method for wrought iron railings. Background technique [0002] Wrought iron railing products are wrought iron components used to isolate and shield specific spaces, interfaces, and objects, and at the same time play a certain ornamental effect. It can be roughly divided into balcony wrought iron fence, wall decoration and garden wrought iron fence, escalator wrought iron fence and other alternative wrought iron fence. [0003] At present, a large number of wrought iron railing products produced according to the traditional design and manufacturing process on the market mainly have the following deficiencies: (1) ignore the crevice corrosion that may occur during the service of the guardrail products and the manufacturing factors and construction factors that cause the inner wall to corrode first; (2) ) At ...

Problems solved by technology

[0003] At present, a large number of wrought iron railing products produced according to the traditional design and manufacturing process on the market mainly have the following deficiencies: (1) ignore the crevice corrosion that may occur during the service of the guardrail products and the manufacturing factors and construction factors that cause the inner wall to corrode first; (2) ) At present, the traditional process commonly used in the whole industry is to directly select galvanized sheets and galvanized pipes for welding and grinding, and then paint the surface and sell them directly as finished products

[0004] However, when the galvanized steel or wrought iron railings made in the above technical solutions are used in some public places, people will often touch them with their hands, which increases the transmission routes of pathogenic microorganisms such as bacteria and viruses, which is not conducive to people's health; Therefore, making the wrought iron railings have a bactericidal function and reducing the probability of bacteria spreading between humans through the railings is one of the technical problems that those skilled in the art need to solve urgently.
