Jiangsu is anticorrosive anti-corrosion company through various means, to protect the rusting of metal objects, to achieve the purpose of prolonging the service life, corrosion resistance, chemical corrosion, electrochemical corrosion and other physical methods commonly used.
Corrosion protection of steel structure of Jiangsu anti corrosion company
Scope: corrosion of large steel structure, such as lightning tower, sea lighthouse, large reservoir, water gate tower, offshore oil production facilities, tanker, tank, storage tank, oil tank, carbonization tower, heat exchanger, chimney, container, ship, offshore platform steel structure and so on, are in the marine atmosphere and long-term industrial atmosphere corrosive environment. To long-term use, rather than a large area of maintenance, long-term coating protection is the best for the former, the service life of up to 20-30 years, maintenance costs less, can obtain obvious economic benefits.
The corrosion characteristics of steel structure under atmospheric environment by the sun, wind, rain and snow, frost and season variation of temperature and humidity, the moisture and oxygen in the atmosphere is an important factor causing outdoor steel structure corrosion caused by corrosion of steel structure, industrial gas containing SO2, CO2, NO2, CI2, and H2S NH3, although the content of these ingredients is very small, but it should not be neglected in the iron and steel corrosion, which SO2 has the greatest effect, CI2 can make the metal surface passivation film is destroyed. These gases are soluble in water, acid, acid rain, corrosion of metal facilities. The characteristics of the ocean atmosphere contains a lot of salt, mainly NaCI, salt particle deposition on the surface of the metal, because it has the effect of increasing the moisture and suction conductive liquid film on the surface while CI- itself has very strong erosion, which aggravated the corrosion of metal surfaces. The corrosion of steel structure is more and more serious, and the corrosion rate is much higher than that of the interior atmosphere.
Protection methods: metal zinc, aluminum has a great resistance to atmospheric corrosion characteristics. In the iron and steel components, zinc, zinc, aluminum, zinc, aluminum is the negative potential and iron and steel to form a sacrificial anode protection function so that the steel has basically been protected. At present, the spray coating is used to prevent the corrosion of atmospheric and oceanic atmosphere:
(1) the combination of aluminum coating and steel matrix has a strong bonding strength, long coating life and good long-term economic benefits;
(2) flexible, suitable for large and difficult maintenance of the steel structure of long-term protection, can be on-site construction;
(3) spraying zinc or sprayed aluminum coatings and anti-corrosion coatings closed, can greatly extend the life of the coating, from the theoretical and practical application of the effect of point of view, spraying zinc or sprayed aluminum coating is the best bottom. Metal spray coating and anticorrosion coating of the composite coating protective life than metal spray coating and anticorrosive coating protective layer two and longer life, for a single coating layer life several times.
Long term heavy duty coating by primer, intermediate paint and paint composition.
From long-term economic considerations, the most economical spray coating, but a one-time investment, the construction of a good coating can be in 10 years without maintenance. Intermediate epoxy zinc rich primer + epoxy micaceous iron oxide paint and acrylic polyurethane long-acting protection system has better economy.
Jiangsu anticorrosive company rubber lining anticorrosion and also known as butyl rubber lining. Ding Ji rubber, formed by cationic polymerization of isobutylene and a small amount of isoprene. The gas permeability of small Ding Ji rubber is its biggest characteristic, impact elasticity of its small, but the shock absorption, chemical stability, weatherability, heat resistance, ozone resistance, etc. are all good, but its curing speed is slow, and the low bonding strength of metal. The application of Ding Ji in the rubber lining, mainly used in rubber made of presulfuration of Ding Ji, the surface of the substrate by self vulcanization adhesive lining of large equipment can not heat vulcanization of the. Ding Ji also used natural rubber paste paste with hot air seam welding, vulcanization can be carried out in the 100 ~ C air or water, can be used for lining 100 ~ C is to prevent the corrosion of the equipment without vulcanization, pre vulcanized or vulcanized rubber plate or sheet.
The rubber lining in metal or other material surface with lining sheet forming a continuous isolation layer technology called lining technology.
Lining plastic materials can be divided into soft plastic, hard rubber and semi hard rubber, generally based on the use of conditions with NR, CR and SBR, etc.. The manufacturing process includes the lining of the metal substrate surface treatment, lining sheet processing, cutting, laminating and curing etc.. Lining sheet as chemical anti-corrosion, anti mechanical wear materials widely used in mines, metallurgy and chemical equipment lining with mud pump, flotation machine, milling machine, building materials industry for cement mill equipment lining. The ability to protect metal or other substrates from various media, and the corrosion of acid, alkali, inorganic salts and various organic matters. And has good elasticity, abrasion resistance, impact resistance and adhesion properties of metal and other matrix. Widely used in petroleum, chemical, fertilizer, metallurgy, electric power of acid and alkali storage tank, reactor, floor isolation layer, etc..
Anticorrosion of glass fiber reinforced plastics in Jiangsu
Advantages of glass fiber reinforced plastic corrosion protection project
Corrosion resistant resin and glass fiber surface felt are used to prevent corrosion layer of glass fiber reinforced plastics. The corrosion resistance is high, the strength is good, and the service life is long. In recent years, is widely used in electric power, metallurgy, glass, petroleum chemical industry, printing and dyeing, machinery, environmental protection and other industries in the storage tank, pickling tank, storage tank, storage tank, acid-base workshop building. So what is the advantage of FRP corrosion protection project?
