Description
TARIFNAME METALIK YÜZEYLERDE BIYOSIT ÖZELLIKLI KIREÇLENME VE KOROZYON ÖNLEYICI BIR KOMPOZISYON Teknik Alan Bulus, alkali sogutma sulu sivilariyla temas halinde olan endüstriyel sogutucular, sogutucu kuleleri, kapali sogutma sistemleri gibi su sirkülasyonlu sistemlerde bulunan sogutucularin demir, alüminyum ve galvanizli çelikten yapilmis yüzeyleri de dahil olmak üzere metalik yüzeylerde korozyonun önlenmesine yönelik bir kompozisyon ilgilidir. Bulus konusu kompozisyon ayrica mikrobiyolojik büyümeyi kontrol etmede (önleme, engelleme, çikarma vb.) ve metalik yüzeylerde kireç olusumunu indirgemede etkilidir. Teknigin Bilinen Durumu Çesitli endüstriyel islemlerde, metal yüzeylerin su ile temas etmesi gerekir. Çogu durumda su oksijenle doymus oldugundan, kosullar metalin korozyonunu tesvik eder. Bu tür aparatlarda yaygin olarak kullanilan metaller arasinda demir, galvanizli çelik, alüminyum, bakir ve bu tür metallerin alasimlari bulunur; bunlardan ikisi veya daha fazlasi normalde ayni aparatta bulunan ve tümü korozyona maruz kalan metallerdir. Metallerde korozyonun önlenmesi için kullanilan maddeler örnek TR2019/04786 numarali patent basvurusudur. Basvuruda bitüm içeren polyurea malzemesi esasli bir kaplama maddesi açiklanmaktadir. Genellikle göl veya akarsu gibi bir yüzey suyu kaynagi tarafindan saglanan sogutma suyu, çok çesitli kirleticiler içerir. Bu kirleticiler kirlenmeye ve ardindan sogutucu akisinin ve /veya isi transfer verimliliginin azalmasina neden olabilir. Kalsiyum, magnezyum ve silika gibi mineraller, borularin ve borularin iç kisimlarinda kireç birikintileri olusturabilir. Rüzgarla sogutma suyu sistemine tasinan veya suyu olusturan bakteriler de ayni sekilde tortu olusturarak proses borularini ve isi degisim yüzeylerini kirletebilir. Bakteriyel kontaminasyon özellikle zahmetlidir çünkü isi esanjörü yüzeylerden isi transferini önemli ölçüde azaltir, bakteriyel balçik tabakasinin altinda korozyon meydana gelebilir ve balçik tabakasinin yapiskan yapisi minerallerin kolayca birikebilecegi bir yüzey saglar, ayrica saglik sorunlari da vardir. Ek olarak, bu tür islemlerde, suda çözünmüs kalsiyum, magnezyum ve benzerleri gibi sertlik üreten katyonlar nedeniyle metal yüzeylerde kireç birikmesi meydana gelebilir. Bu tür kireç birikimi, metal yüzeylerin isi transfer kabiliyetini engeller, korozyon önleyici maddelerin metal yüzeye ulasmasini Bu tür metal korozyonu, mikrobiyal büyüme ve tufal olusumu ekonomik ve endüstriyel açidan ciddi bir sorun oldugundan, geçmiste bunlari azaltmaya yönelik birçok girisimde bulunulmustur. Soruna çözüm olarak, korozyon önleyici kimyasallarin, biyositlerin ve tufal inhibitörlerinin eklenmesidir. Bu amaçla yaygin olarak kullanilan kimyasallar; sodyum nitrit, kromatlar, silikatlar, boratlar, çinko bilesikleri, çesitli tipteki fosfatlar ve azol bilesiklerini içerir. Bu yöntem, çevreye potansiyel tehlikeleri nedeniyle daha önce kullanilan kimyasallarin birçogunun kullanimini sinirlar. Örnegin TR2011/04039 nolu ulusal patent basvurusunda bulus sogutma suyu sartlandirilmasinda kullanilan fosfat veya polimer bazli korozyon-kisir inhibitörleri, dispersan maddeler ile biyositler ve klorlu bilesikler yerine insan/çevre dostu tanen bazli kimyasallarin tek ürün olarak kullanimi ile ilgilidir.

TR TR TR TR DESCRIPTION AN ANTI-LICALE AND CORROSION PREVENTIVE COMPOSITION WITH BIOCIDE PROPERTIES ON METALLIC SURFACES Technical Field The invention is intended for metallic surfaces, including the surfaces made of iron, aluminum and galvanized steel, of coolers in water circulation systems such as industrial coolers, cooling towers, closed cooling systems, which are in contact with alkaline cooling water fluids. A composition for preventing corrosion on surfaces is relevant. The composition of the invention is also effective in controlling microbiological growth (prevention, inhibition, removal, etc.) and reducing scale formation on metallic surfaces. State of the Art In various industrial processes, metal surfaces must come into contact with water. Since water is saturated with oxygen in most cases, the conditions promote corrosion of the metal. Metals commonly used in such apparatus include iron, galvanized steel, aluminum, copper, and alloys of such metals; Two or more of these are metals normally found in the same apparatus, all of which are subject to corrosion. An example of substances used to prevent corrosion in metals is the patent application number TR2019/04786. The application discloses a coating material based on polyurea material containing bitumen. Cooling water, usually provided by a surface water source such as a lake or stream, contains a wide variety of contaminants. These contaminants can cause fouling and subsequent reduction of refrigerant flow and/or heat transfer efficiency. Minerals such as calcium, magnesium and silica can form lime deposits on the inside of pipes and pipes. Bacteria carried into the cooling water system by wind or forming water can also form sediment and contaminate process pipes and heat exchange surfaces. Bacterial contamination is particularly troublesome because it significantly reduces heat transfer from heat exchanger surfaces, corrosion can occur beneath the bacterial slime layer, and the sticky nature of the slime provides a surface on which minerals can easily accumulate, as well as health problems. Additionally, in such processes, scale build-up may occur on metal surfaces due to hardness-producing cations such as calcium, magnesium and the like dissolved in water. Since this type of metal corrosion, microbial growth and scale formation is a serious economic and industrial problem, many attempts have been made in the past to reduce them. The solution to the problem is the addition of corrosion inhibitor chemicals, biocides and scale inhibitors. Chemicals commonly used for this purpose; sodium nitrite, chromates, silicates, borates, zinc compounds, various types of phosphates and azole compounds. This method limits the use of many previously used chemicals due to their potential danger to the environment. For example, in the national patent application no. TR2011/04039, the invention is related to the use of human/environmentally friendly tannin-based chemicals as a single product instead of phosphate or polymer-based corrosion-killing inhibitors, dispersant substances, biocides and chlorinated compounds used in cooling water conditioning. However, these mixtures consisting of organic acids and herbal ingredients will not create a sufficient synergistic effect in descaling, corrosion prevention and biocidal effect. As a result, due to the negativities described above and the inadequacy of existing solutions on the subject, it has become necessary to make a development in the relevant technical field. Purpose of the Invention: The invention is inspired by existing situations and aims to solve the above-mentioned drawbacks. The primary object of the invention is to provide a novel corrosion inhibitor and biocide composition for use in aqueous systems, including but not limited to water circulation systems such as chillers and closed cooling systems. It consists of a synergistic combination that is based on green chemicals and is effective at low levels of such chemicals. Another aim of the invention is to provide a new, anti-corrosion and biocide composition with outstanding effectiveness in both corrosion prevention and free-living microorganisms and biofilm control. The inclusion of trisodium phosphate and sodium polyacrylate acts to reduce corrosion inhibition by cleaning the surfaces. The inclusion of di-cyclohexyl amine nitride acts as a corrosion inhibitor on metals. The components have a synergistic effect when used in combination in aqueous systems. The composition of the corrosion inhibitor and biocide composition provides a water-soluble composition containing a suitable synergistic formulation of sodium glucoheptonate, zinc gluconate, sodium borate, sodium nitrite, dicyclohexylamine nitrite, benzotriazole (BTA), carboxybenzotriazolester (CBTE), sodium silicate. Another aim of the invention is to provide corrosion protection as well as to provide a non-toxic biocide, an applicable composition that is friendly to the environment, green and humans. In order to fulfill the above objectives, the invention is a composition that prevents calcification and corrosion with biocide properties on metallic surfaces and its feature is; Contains Sodium Nitrite, Sodium Glucoheptonate, Zinc Gluconate, Dicyclohexylamine Nitrite, Benzotriazole, Carboxy Benzotriazole, Trisodium Phosphate, an iodine salt. The iodine salt mentioned herein may contain one or more selected from the group consisting of zinc iodide, potassium iodide, sodium iodide. An embodiment of the invention may further include one or more selected from the group consisting of Sodium Borate, Sodium Silicate, Sodium Benzoate. An exemplary embodiment of the invention contains 15-30% Sodium Nitrite, 3-12% Sodium Glucoheptonate, 15-30% Zinc Gluconate, 2-8% Dicyclohexylamine Nitrite, by weight. An exemplary embodiment of the invention includes one or more selected from the group consisting of 2-15% Sodium Borate, 2-6% Sodium Silicate, 3-7% Sodium Benzoate by weight. An exemplary embodiment of the invention contains, by weight, 21% Sodium Nitrite, 8% Sodium Glucoheptonate, 21% Zinc Gluconate, 10% Sodium Borate, 4% Dicyclohexylamine Nitrite, 4% Benzotriazole, 5% Carboxy Benzotriazole, 4% Sodium Silicate, 7% Sodium Benzoate, Contains 4% Trisodium Phosphate, 8% Zinc Iodide. The structural and characteristic features and all the advantages of the invention will be more clearly understood thanks to the figures given below and the detailed explanation written by making references to these figures, and therefore the evaluation should be made taking these figures and detailed explanation into consideration. Detailed Description of the Invention In this detailed explanation, the preferred embodiments of the composition that are the subject of the invention are explained only for a better understanding of the subject. His invention is a composition that prevents scaling and corrosion with biocide properties on metallic surfaces such as cooling water systems. In its basic form, it contains Sodium Nitrite, Sodium Glucoheptonate, Zinc Gluconate, Dicyclohexylamine Nitrite, Benzotriazole, Carboxy Benzotriazole, Trisodium Phosphate and Zinc Iodide. The preferred embodiment of the invention also includes one or more selected from the group consisting of Sodium Borate, Sodium Silicate, Sodium Benzoate, and the composition ratios are given in Table 1. Table 1. Anti-corrosion composition for cooling water systems Content Preference by weight Quantity by weight Available (%) quantity (%) Sodium Nitrite 21 15-30 Zinc Gluconate 21 15-30 Sodium Borate 10 2-15 Sodium Glucoheptonate 8 3-12 Zinc Iodide 8 1-8 Sodium Benzoate 7 3-7 Benzotriazole 4 3-7 Sodium polyacrylate 4 2-6 Sodium Silicate 4 2-6 Trisodium Phosphate 4 2-6 Corrosion inhibitor with biocide (Zinc iodide or potassium iodide or sodium iodide) in the composition of the invention The combination of substances (zinc gluconate, sodium borate and sodium benzoate) serves to control microbial growth. The conjugated biocide composition also improves the performance of self-wear inhibitors by being supplemented with anti-corrosion agents. Thus, corrosion inhibitors and biocide agents integrate and synergize with each other in a properly balanced formulation. It contains a synergistic formulation of benzotriazole and carboxy benzotriazole ester. Copper and its alloys are protected by a combination of benzotriazole and carboxy benzotriazole ester. The synergy of benzotriazole (BTA) and carboxy benzotriazolester (CBTE) is 2 ppm BTA and 3 ppm CBTE. Zinc gluconate has proven to be an excellent corrosion inhibitor for copper, aluminum, zinc and steel in harsh environments including aerated seawater. The combination of sodium nitrite and sodium borate provides the same corrosion protection and passivation power as sodium dichromate. Calcium glucoheptonate and zinc gluconate prevent the dissolution of iron from the pores of the passive layer. Thus, complete corrosion protection is achieved. According to the invention, the optimum concentration of sodium nitrite was found to be 21% by weight. Sodium nitrite provides sufficient corrosion inhibition by forming a YFe2O3 layer. The higher the concentration of sodium nitrite, the better the corrosion protection against chloride and other aggressive ions. The addition of sodium borate, zinc gluconate, sodium benzoate and calcium glucoheptonate will reduce the required nitrite concentration while ensuring full protection of the metal surface. When iron is not protected by a corrosion inhibitor, it continues to corrode due to available oxygen, carbon dioxide, corrosive ions, changing temperatures and heat fluxes. In well-rusted iron, layers consisting of various oxides of red and black rust are observed. The oxide layers prevent the iron from further corrosion. With a synergistic formulation of sodium nitrite, zinc gluconate and glucoheptonate, borate inhibitors, it will clog the iron pores and ensure complete protection of the passivated iron surface. In this sense, gluconate acts as an anodic inhibitor. Zinc ions form a concentrated zinc hydroxide to block any cathodic sites creating a cathodic inhibitor. Benzoate and phosphate provide a film barrier to further protect the blocking layer. Therefore, the synergistic combination of sodium nitrite, calcium glucoheptonate, zinc gluconate, phosphate, benzoate and borate provides anodic and cathodic inhibition, buffering and film-forming barrier on metal surfaces of cooling systems, passivating steel, passively blocking pores. The layer with an adsorbed chelate complex of iron ions blocks any cathodic sites with zinc hydroxide and prevents chloride ion adsorption on the steel. The corrosion inhibitor and biocide components are in fine powder form. The composition of the invention is prepared as follows: - Preparing the ingredients explained in Table 1 in predetermined proportions, - Mixing the prepared ingredients preferably for 30 minutes, - Filling the prepared mixture into waterproof bags, - Sewing or sealing the bags and storing them in a dry environment without moisture. Inhibitors found in powder form during the preparation phase can be dissolved by adding them to the coolant. The steady-state concentration of the inhibitor depends on the chemistry of the cooling water. TR TR TR TR
