Degreasing Rust Combo decontamination liquid "before technical presentations metal and some non-performing protective construction shall be carried out surface preparation, in order to increase the adhesion of the protective layer, the protective layer to ensure the decorative effect for the subsequent process to be carried out create conditions - to oil, rust surface treatment indispensable step is to ensure the quality of the protective layer an important part - a commonly used method to oil rust - rust methods commonly used chemical-based rust Chemical rust using a variety of acid, hydrochloric acid and sulfuric acid most widely used. acid can react chemically with rust or metal oxide to form soluble salts, so rust is removed, the acid can react with the matrix metal release hydrogen, hydrogen for rust and scale produce insoluble pressure is conducive to their high iron reduction flaking and accelerate the pickling process, but also will produce hydrogen side effects: - 1, hydrogen embrittlement of the metal, causing the mechanical properties of metals drop; - 2, large amount of hydrogen evolution will form mist, affecting their health and corrosion around the equipment operator; --3, consume large amounts of acid to increase processing costs; -. 4, easy to produce excessive corrosion - common degreasing method, there are two kinds of lye cleaning and solvent cleaning -. (a), alkaline cleaning commonly used materials are sodium hydroxide, sodium carbonate, trisodium phosphate, sodium silicate and other alkaline cleaning formulations with improved cleaning and improved methods of operation, it has degreasing capability, safety and reliability advantages, but alkaline cleaning defects are obvious: - 1, some lye easily cleaned with water; - 2, some lye need heating, spend energy; --3, some lye is corrosive to non-ferrous metals; - 4 different treatment processes need to select a different material with the ratio of the actual application is not easy to grasp; - 5 and higher costs - (b). with a degreasing solvent cleaning effect, it can be cleaned at room temperature for ferrous and nonferrous metals from corrosion advantages. selection of materials are petroleum solvents, aromatic solvents, halogenated hydrocarbons, turpentine, etc. It is well known organic solvent is flammable explosive, and a certain toxicity of dangerous goods, while more volatile, air pollution, harm to human, material consumption, high production costs, has been very limited in industrial applications - the Second, "to oil rust Combo decontamination liquid "superiority - 1, good effect of the product can effectively remove the oil on the oil, rust and non-metallic surfaces on metal surfaces, providing a clean surface for the subsequent process no hydrogen embrittlement and excessive corrosion. ; 2, low cost, with less product costs about 350 yuan / ton, Fe2 + content in 150g / L or less, and can be used effectively; -. 3, the process is simple to follow oil rust simultaneously in addition to the oil. Rust process subject to the oil - water - rust - washing and other four processes in order to obtain a clean surface, using the technology only comprehensive treatment - washing two processes to simplify procedures, improve efficiency, save production sites and production equipment; --4, improve the production conditions of the product without mist generated is conducive to environmental protection, labor protection and production equipment maintenance, and reduce consumption of raw materials; - 5 easy to use. The product is formulated at room temperature, use and help save energy, reduce processing costs; - 6, use of safety. Product non-flammable, non-explosive, non-toxic, odorless, harmless; - 7 and versatile. It can be widely used in metal and some non-metallic materials in painting, electroplating, electroless plating, rust-proof seal, surface modification, pretreatment mask table conversion and other technology. Third, the technology provides ways - the product is also suitable for the new generation of "environmentally-friendly surface alloy catalyst liquid" pretreatment process in dealing with the process. The Centre for the confinements catalyst solution customers free of the technology, will be "environmentally friendly surface alloy catalyst solution," the promotion and application of tales of the many advantages. - The product is suitable for both self-made surface treatment business for personal use, but also as a cleaning fluid commodity sales operations. Currently, the market price of similar products imported up to 12,000 yuan / ton, the retail price is as high as 20 yuan / kg. In China, there are tens of thousands of electroplating enterprises only, therefore, the demand for the product is huge, very substantial economic benefits. Protective metal and some non-performing pre-construction, surface preparation must, in order to increase the adhesion of the protective layer, the protective layer to ensure the decorative effect, to create conditions for the subsequent process to be carried out. - To oil, rust surface treatment is an indispensable step is to ensure the quality of the protective layer is an important part. - A commonly used method to oil rust - rust removal methods commonly used chemical-based rust. Chemical rust using a variety of acid, hydrochloric acid and sulfuric acid most widely used. Acid can play with rust or metal oxide chemical reaction to produce soluble salts, so rust is removed, the acid can react with the matrix metal release hydrogen, hydrogen to rust and insoluble oxide generated pressure is conducive to their spalling and high iron reduction, accelerate the pickling process, but also will produce hydrogen side effects: - 1, the metal hydrogen embrittlement caused by the mechanical properties of the metal fell; - 2, will form a large amount of hydrogen evolution mist, operator Health personnel and equipment corrosion around; --3, consume large amounts of acid to increase processing costs; --4, easy to produce excessive corrosion. - Commonly used methods to oil, there are two kinds of lye cleaning and solvent cleaning. - (A), alkaline cleaning commonly used materials are sodium hydroxide, sodium carbonate, trisodium phosphate, sodium silicate. Alkaline cleaning with cleaning to improve the formulation and method of operation improved, it has a strong ability to oil, safety and reliability advantages, but alkaline cleaning defects are obvious: - 1, some lye easily cleaned with water; - 2 Some lye need heating, energy consumption; - 3 and some lye is corrosive to non-ferrous metals; - 4 different treatment processes need to select a different material with the ratio of the actual application is not easy to grasp; - 5 higher cost. - (B), with a degreasing solvent cleaning effect, cleaning at normal temperature, the merits of ferrous and nonferrous metals from corrosion is. Selection of materials are petroleum solvents, aromatic solvents, halogenated hydrocarbons, such as turpentine. As we all know, it is a flammable organic solvents, and have a certain toxicity of dangerous goods, while more volatile, air pollution, harm to human, material consumption, high production costs and therefore subject to very limited use in the industrial. - Second, the superiority "to oil decontamination liquid rust combo" of - 1, good results. The product can effectively remove the oil on the oil, rust and non-metallic surfaces on metal surfaces, providing a clean surface for subsequent processes. No hydrogen embrittlement and excessive corrosion; 2, low cost, with less. Product costs about 350 yuan / ton, Fe2 + content in 150g / L or less, can be used effectively; - 3 simple process. We will go to the oil rust simultaneously. Follow degreasing rust process subject to the oil - water - rust - washing and other four processes in order to obtain a clean surface, using the technology only comprehensive treatment - washing two processes. Simplify procedures, improve efficiency, save production sites and production facilities; --4, improving production conditions. The product is no mist generated is conducive to environmental protection, labor protection and production equipment maintenance, and reduce consumption of raw materials; - 5 easy to use. The product is formulated at room temperature, use and help save energy, reduce processing costs; - 6, use of safety. Product non-flammable, non-explosive, non-toxic, odorless, harmless; - 7 and versatile. It can be widely used in metal and some non-metallic materials in painting, electroplating, electroless plating, rust-proof seal, surface modification, pretreatment mask table conversion and other technology. Third, the technology provides ways - the product is also suitable for the new generation of "environmentally-friendly surface alloy catalyst liquid" pretreatment process in dealing with the process.
