Huaian anti-corrosion company steel structure anticorrosion
 
Corrosion of scope: large steel structure such as brake, lightning rod tower, sea lighthouse, large reservoir, water towers, offshore oil facilities, tank car, spherical tank, storage tank, oil tank, carbonization tower, heat exchanger, chimney, container, ship hulls, offshore platform steel structure, etc., are all under Marine atmospheric, industrial atmospheric corrosion environment for a long time. If you want to use for a long time, but not for large area maintenance, long-term protective coating for best before, the service life of up to 20 to 30 years, less maintenance, can obtain obvious economic benefit.
 
Corrosion features: steel structure of the atmospheric environment by the sun, wind, rain and snow, frost and dew, and the function of temperature and humidity change by all the year round, including atmospheric oxygen and the moisture is the important factors of corrosion of outdoor steel structure, steel structure corrosion caused by the industrial gases containing SO2, NO2, CI2, H2S, CO2 and NH3, although these ingredient content is very small, but the steel corrosion harm is not to be ignored, which had the greatest influence of SO2, CI2 can make the metal surface passivation film is destroyed. The acidic gases dissolve in water, acid rain formation, corrosion of metal facilities. The characteristics of the Marine atmosphere is contains a lot of salt, mainly NaCI, salt particles falling on metal surface, due to its moisture absorption and increase the conductive effect of the liquid film and the CI - itself and has a strong corrosive, and thus increase the corrosion of the metal surface. Steel structure near the coast, the corrosion is serious, the corrosion speed is many times higher than the interior atmosphere.
 
Protective methods: metal zinc, aluminum has a great deal of characteristics of the resistance to atmospheric corrosion. On steel components spraying zinc or aluminum, zinc, aluminum, steel of the negative potential, and sacrificial anode protection so that the basic protected steel. Now with aluminum coating to prevent corrosion of industrial atmosphere, ocean, atmosphere, its characteristic is as follows:
(1, solid, coating aluminum coating and steel substrate, long service life, good long-term economic benefits;
(2, the craft is flexible, suitable for important large and difficult maintenance of long-term protection of steel structure, site construction;
(3, spraying zinc or aluminum coating anticorrosive coating is closed, can greatly prolong the service life of coating, from the point of view of theory and practical application effect of spraying zinc or aluminum coating is the best bottom anticorrosive coating. Metal spray coating and coating of anticorrosion coating of composite coating protective life was anticorrosive coating and metal coating layer and protective layer of the two combined long service life, life several times for a single coating layer.
Long-term anti-corrosion coatings composed of primer and intermediate paint and paint.
From long-term economic consideration, aluminum coating the most economical, but to invest big, construction good coating can be in 10 years without maintenance. Epoxy zinc rich primer + epoxy micaceous iron oxide intermediate paint and acrylic polyurethane long-term protection system has a better economy.

The advantage of glass fiber reinforced plastic anti-corrosion engineering
 
Glass fiber reinforced plastic anti-corrosion engineering using corrosion resistant resin and glass fiber surface mat for anti-corrosion layer, unsaturated polyester resin and strengthening of alkali-free glass fiber cloth layer, high strength, good corrosion resistance, long service life. In the past two years, is widely used in electric power, metallurgy, petroleum, chemical industry, printing and dyeing industry, machinery, environment protection, etc of the storage tank, storage tank, reservoir, reservoir, acid and alkali workshop building, etc. So what kind of glass fiber reinforced plastic anti-corrosion engineering have advantage?
1, light weight, high strength: the proportion of glass fiber reinforced plastic is only 1.4 to 2.0, while the tensile strength of the filament wound FRP can reach 300-500 mpa, the ultimate tensile strength than ordinary steel, such as according to the strength calculation, also has reached or exceed certain special alloy steel, thus can be used as anticorrosive equipment of the main structure material, and possesses the advantages of convenient transportation, installation and maintenance.
2, good corrosion resistance: one of the biggest characteristic of glass fiber reinforced plastic, corrosion resistance is good. Through the resin type and brand of choice, using the appropriate molding process, can produce a variety of acid resistance, alkali, salt and organic solvents of glass fiber reinforced plastic products.
3, good surface performance, and ease of cleaning and sterilization performance: because of the glass fiber reinforced plastic molding of a whole, no seams, wall smooth, contact with chemical medium, surface few corrosion products and scaling phenomenon, more not breed bacteria and microorganisms. So there is no pollution medium, easy to clean, the food and drug administration specialized inspection, glass fiber reinforced plastic has reached the requirement of food brewing, medicine industry.
4, can design: glass fiber reinforced plastic is a kind of can change the raw material type, quantity proportion and reinforced material arrangement way, in order to meet the different performance requirements of composites.
5, good construction technology: no curing of the resin and reinforced material has the ability to change shape, therefore, can through different methods of molding and mold easily processed into the required shape. This feature is most suitable for large, integrated and complex equipment and construction requirements, and is suitable for site construction and assembly.
6, anti-aging, flame retardant, fiberglass reinforced plastics is category of products, there is a natural aging and substrate material burning question. But after 60 years in the world, after more than 30 years of research in China, has been preliminarily solved, reinforced material and coupling agent treatment, use of 50 years, the bending strength can keep long in 64-46%, the tensile strength retention rate at 71.2%, with addition of stabilizer, again as anti aging performance is better; Adding flame retardants and the glass substrate by adding flame retardant, flame retardant resin oxygen index of 34-36, fully satisfy the requirement of the fermentation equipment flame retardant fire.
7, low comprehensive cost: glass fiber reinforced plastic as a kind of new functional materials, due to the high prices of the raw materials used. Generally speaking, glass fiber reinforced plastic equipment is higher than the price of carbon steel and some plastic equipment, and lower than stainless steel and other non-ferrous metal equipment. But as a result of glass fiber reinforced plastic and light weight, good corrosion resistance, long service life, less maintenance, its installation, use and comprehensive cost is low; And for some complex or harsh equipment using conditions, can be used to each director, such as heating plate works of stainless steel or titanium, lined with thermoplastics, etc., in order to achieve both have excellent properties and can reduce the cost of purpose. The structural layer thickness to adjust different medium and load.
Glass fiber reinforced plastic anti-corrosion engineering, of course, also has its own weaknesses, such as long-term low temperature resistance and low interlaminar shear strength. But these problems with the development of science and technology, design of transformation and the emergence of various kinds of modifier will be well resolved.
 
 
 
Huaian anticorrosion company rubber lining, also known as butyl rubber lining. Butyl rubber, isobutylene and a small amount of isoprene cationic polymerization. Butyl rubber small gas permeability is the biggest characteristic of the impact of its elasticity is small, but the shock absorption, chemical stability, weather resistance, heat resistance, ozone resistance, etc., but its curing speed is slow, and the bonding strength of the metal is low. Butyl rubber in the application of the lining, mainly used to make precure butyl rubber sheet, using the vulcanizates goo affixed lining can't be in the hot vulcanization of large equipment of the surface of the substrate.
