Application of glass and steel in anti-corrosion facilities

glass and steel a large number of and commonly used in the field of corrosion resistance, in the industrialdeveloped countries have more than 30 history, domestic corrosion-resistant glass steel since the early 1950s has been a large randalization of the development, especially in the last 20 years, with the introduction of raw materials and products related to corrosion-resistant glass steel manufacturing equipment and technology, corrosion-resistant glass steel products in various areas of the national economy more and more extensive1, frittos are widely used in the field of environmental protection
with the development of industry, environmental pollution has become one of the world's most concerned issues, many countries invest huge human and material resources, committed to environmental protection industry, a new industrial sectorglass steel has been widely used in water supply and drainage pipeline engineeringAccording to the information provided by the four largest glass and steel manufacturers alone, they have been made of 2600km of water supply and drainage pipes with glass steel as early as 1984 and put into use, in recent years, more and more types of wastewater and corrosion media and corrosion intensity are increasing, which requires the use of better corrosion resistance materials, and corrosion-resistant fritsteel is the best material to meet this demand, for which Germany in 1983 issued the first official standard, the nominal diameter of the glass steel pipe is 400-10000000composite materials in environmental protection applications include general industrial waste gas treatment, oil water treatment, toxic sewage treatment, waste incineration treatment and municipal wastewater deodorization treatment2, glass and steel storage tanks in high purity water and food applications:this is a new field of glass and steel applicationsThe excellent corrosion resistance of the glass and steel means that the material has a lively, non-polluting properties that can naturally become highly clean items, such as the storage of high purity water, medicine, wine, milk and other optional materialsForeign countries in the past 10 years in this field has a greater development, the United States, Japan have such products of professional factories, in the use of a wealth of experienceIt is reported that the domestic has also begun to develop work in this regardThe experience of practical application shows that the following links should be noted: A resin selection has strict requirements, B process in the case of a system, C design installation has certain requirements3, glass steel storage tanks, towers in the chlor-alkali industry applications:chlor-alkali industry is one of the earliest applications of glass steel as a corrosion-resistant material, at present, glass steel has become the main material of chlor-alkali industryAs early as the early 1950s, frittore was first used to collect heat (93 degrees C), wet chlorine, and organic matter from ink electrodesThis application replaces the phenolic asbestos plastic of the timeLater, the glass steel was used to replace the concrete electrolytic cell cover, which solved the problem of the corrosion of concrete debris falling into the electrolytic cell Since then, frittosteel has been gradually used in a variety of piping systems, gas drum maneuvering, heat exchanger shell, salt water tank so that pumps, pools, flooring, wall panels, grilles, handles, railings and other building structures At the same time, fiberglass has also begun to enter all areas of the chemical industry 4, glass and steel storage tanks, towers, pipes in the paper industry applications: paper industry to wood as raw materials, paper making process needs acid, salt, bleach, etc , the metal has a very strong corrosion effect, only the glass steel material can resist the harsh environment such as mycobacteria, FRP has been in some countries in the pulp production show its excellent corrosion resistance 5, glass steel in the metal surface treatment industry application: metal surface treatment plant used acid, mostly hydrochloric acid, basically with FRP is no problem 6, glass-and-steel pipe desalination: desalination is divided into traditional distillation method and reverse osmosis membrane method, because sea water is very easy to easily easily easily easily easily easily erode iron materials, so most of the pipes and containers in the desalination plant are using FRP products 7, glass and steel insulation tube in the hot spring application: hot spring use of power generation and bathing, from the extraction of hot springs to transport, have been a large number of use of FRP tube, the most suitable material for Novolac ethylene ester, it can withstand the erosion of sulphides at high temperatures 8, glass and steel storage tanks, pipes in the pharmaceutical industry applications: a wide variety of drugs, each raw material has all the same, corrosion situation is also many, so FRP is also favored in the pharmaceutical industry
