Africa-Press – Angola. A technological solution to prevent wear and tear suffered by a metal part was presented this Tuesday, in Luanda, for the maintenance of structures and to increase their useful life.
The “Rustless Anticorrosive Technology” solution comes from the company Rustless, headquartered in Brazil, but with representation in the United States, Canada, Mexico, Turkey, Portugal and now also in Angola.
Speaking to the press, after the presentation ceremony, the founder of Rustless technology, Jefferson Tasca, says that the technology has a technical and scientific patent registered in 153 countries, being in operation in 8 countries, commercially serving 23 countries.
According to him, the technology arrives in the country to carry out the operations, for “we bring benefits from the use of technology for metallic structures exposed to the most varied types of corrosives”.
“Angola is experiencing a moment of transformation, which combines with our technology, as it is the only one in the world capable of paralyzing active corrosive processes and preventing the formation of new corrosive processes”, he stressed.
According to the person in charge, this technology extends the useful life of the metal on ships, oil platforms, that is, where any type of metallic structure exists.
The executive director and representative of the brand in Angola, Benedito Marlon Agostinho, considers Rustless to be a technology that focuses more on clean energy and against environmental pollution.
“In a smart way, we fight corrosion on all metals. It can be applied to towers, bridges and ships. The technology increases 9 health levels of the metal to be protected. In Angola there is a lot of rust and this is what brought technology to the country”, he said.
He added that there is little maintenance and companies “still use the cathodic way to protect their metals against rust, which is painting, sanding, but with anti-corrosive we manage to present a solution regardless of the type of structure”.
The businessman ensures that at this time they are working with the ports of Luanda and Cabinda to study the implementation of said technology.
In turn, accountant Nelson Itembo, considers it to be an added value, because small and medium-sized companies based in Luanda spend, on average, on maintenance and conservation of metallic infrastructures between 15% and 20% of the expenses incurred. .
Industrial taxes of 6.5%, which are related to maintenance and conservation expenses, have been another concern on the part of managers, who are looking for mechanisms to considerably reduce maintenance and conservation expenses, according to the specialist who spoke to journalists on the sidelines of the presentation of “Rustless Anticorrosive Technology”.
“I have carried out accounting for small and medium-sized companies based in Luanda and expenses with maintenance have been a concern on the part of managers”, he reinforced.
Rustless Anticorrosive Technology, from the company Rustless based in Brazil, has representation in the United States, Canada, Mexico, Turkey, Portugal and now also in Angola.
Available data indicate that around 30% of the world’s production of iron and steel is lost to corrosion, with costs consuming 1 to 5% of countries’ GDP.
Studies indicate that 30% of the metal extracted in nature is used to replace parts and structures damaged or condemned by corrosion.
Corrosion of metals is a natural process resulting, generally, from redox reactions or electrochemical corrosion. In this process, metals suffer wear due to the action of natural agents, such as gas and oxygen present in the air.
An example of corrosion, which occurs in everyday life, is the rusting process of steel wool used to wash utensils in the kitchen.
It is common to observe that it starts to present a reddish color and falls apart after one or two days of use.
Corrosion is a redox process, that is, one material (in this case, the metal) undergoes oxidation (loses electrons), and the other, reduction (gains electrons). To undergo oxidation, the metal must have a reduction potential (Ered) lower than the material that came into contact with it.
