corrosion inhibitor - Opis:
- Corrosion of metals is the gradual destruction of metal under the impact of environmental factors. Chemical or electrochemical processes on the surface of the metal cause irreversible changes in the structure of the metal. To prevent this, during storage or transport, the surfaces of metal elements must be protected against environmental factors, which include: high air humidity, acid rain and variable temperature. These factors accelerate the corrosion process, which cannot be eliminated, but can be reduced by protecting metal elements with e.g. protective oils. Some metals have the ability to passivate, which is a natural protective agent that prevents corrosion. It consists in the formation of an oxide of this metal on the metal surface. Where there is no natural protection against corrosion, protective measures must be used. This paper presents the technology for the production of protective oil for temporary protection against corrosion. The innovation of this project is that the oil will form a thin, well adhering protective layer on the metal surface, which can be easily removed. It is characterised by very low viscosity and low dripping time. It is possible to achieve by using proper base oil with carefully selected anti-corrosion additives. Based on the standard PN-75/C-04154 Petroleum products. Rust protection by metal preservatives the humidity cabinet test method, corrosion tests were carried out. The paper presents the results of a humidity cabinet test for an oil mixture based on deeply refined base oil and properly selected refining additives. The test results confirmed very good anti-corrosive properties of the developed oil due to the use of a corrosion inhibitor and an oxidation inhibitor. The thickness of the protective layer formed on the metal surface was calculated based on a mathematical formula. The resulting layer forms a thin oil film, easy to remove and protecting the metal surface from corrosion.
