Silicon-zirconium coating agent and nickel-free phosphating agent. Many people are familiar with phosphating agent, but less familiar with coating agent. The difference between phosphating agent and film agent is not clear at the time of purchase. Gao Yuan will tell you about phosphating agent and film agent to see what is the difference between phosphating agent and film agent.1. Effect of phosphating agent and coating agentPhosphating agent and coating agent are widely used as a kind of chemical in the pretreatment of professional spraying plants, which can provide a protective film for the sprayed workpiece and add a good adhesion layer for rust prevention and paint, powder, etc.2. Difference between phosphating agent and coating agentPhosphating agent and coating agent are actually the same kind of metal surface treatment agent, but their names are different in different regions.

With the development of the Internet in recent years, e-commerce is becoming more and more popular. No matter what you are looking for, you like to check and find it on the website. One of the specific reasons is that online prices are cheaper than traditional sales prices. Is that true? In fact, not necessarily. Take the price of ceramic chemicals for example:For industrial consumables such as ceramic chemicals, the supplier cannot be selected solely through the price of ceramic chemicals. Today, the market is so transparent, and the price of each ceramic agent means at least three kinds of information:1. The difference of raw materials, whether the raw materials are imported or not, and the brand of raw materials are all directly related. The quality and cost performance of the raw materials produced by different principles are different. Even if it is a small additive, it will directly affect the price of ceramic chemicals.Silicon-zirconium coating agent2. The scale strength, produc...
Phosphorus-free ceramic is a chemical material in chemical production activities, and it has many types. Different types of phosphating agents play different roles in different environments. The temperature of phosphating is an important parameter of phosphating control, which has an important impact on the formation of products. So how is the specific phosphating temperature controlled? Let's get to know Xiao Bian now.The phosphating temperature is an important parameter of phosphating control, which has an important impact on the formation of phosphating film. The medium temperature phosphating temperature has a significant impact on the phosphating film formation speed. This is because of the ionization balance in the phosphating solution, which is an endothermic process. Therefore, the temperature rises, the balance shifts to the right, and the film formation speed increases. However, too high temperature will result in thick and rough phosphating film and increased sediment. T...
Nickel-free phosphating agent is a common product used in many projects to improve the adhesion and corrosion resistance of the workpiece before spraying. In order to achieve better results and save more use costs, there are also many problems that need attention when operating or maintaining the solution. Here are some common problems that need attention, so that everyone can operate better.1. Phosphating agent is acidic product. Please distinguish it when using it to prevent the solution from being invalid due to channeling;2. Heating treatment is required. The coating time depends on the effect, and the coating time of some parts will be prolonged;3. Avoid contact with skin and eyes during use. In case of contact, rinse with plenty of water in time;4. Avoid sun exposure and store it in a ventilated and cool place. The distant phosphating agent is non-flammable, non-explosive and non-corrosive;5. The service life of general phosphating agent is 3-6 months, and the specific time depen...

Many manufacturers will choose to use nickel-free phosphating agent for phosphating treatment before painting metal. Why do you do this? What is the function of phosphating agent? The editor helps you answer.Phosphating agent mainly forms a layer of phosphating film on the metal surface through chemical reaction to improve the corrosion resistance of metal products. It can also play a role in rust prevention and antirust wax on the metal surface, and improve the adhesion of paint spraying, so the metal will choose to undergo phosphating treatment before painting.Phosphating treatmentA layer of non-metallic, non-conductive, porous and continuous phosphate film is formed on the metal surface through chemical reaction. The main component of phosphate is acid phosphate. These acid phosphates, after being dissolved in water, decompose to produce free phosphate, react with the metal on the surface of the workpiece, and form phosphate deposits on the surface of the workpiece. The phosphating ...
Source principle of ceramic agent:1. Zirconate precipitation crystal film: When the surface dissociated zrf6 - is dissolved in the metal ion fe2+and reaches the solubility product constant KSP, the zirconite precipitation will be formed.2. Zirconic acid II dissociation:h2zrf6+h+-zrf62-+2h+Due to the sharp drop of H+concentration on the surface, the dissociation equilibrium of all layers of zirconium is shifted to the right, resulting in zrf6.Nano ceramic agent3. Nano-silicon promotes reaction acceleration:[SI]: ZRO2+4 [H] - [zirconium]+2H2OIn the formula [Si] is a nano-silicon. [Zirconium], in order to reduce the product, nano-silicon dioxide is used as the reaction activator to accelerate the reaction speed, further leading to a sharp drop in the concentration of H+on the metal surface, resulting in the formation of [Zirconium] film nucleus.4. Acid corrosion causes the reduction of H+concentration on metal surface: fe-2 e fe2+, 2 hours+2 e-2 [H]fe2++ ZRF62-+H2O-FEZRF6+2H20The zirconiu...

What is nickel-free phosphating agent? How to use it? The partner who has not used it must be confused. Let's take a look at the relevant content with Xiaobian!Nickel-free phosphating agent is a common chemical raw material in chemical production activities. This kind of raw material can be used to produce many chemical materials. Today we will analyze the development trend of phosphating agent and the key points of phosphating mechanism. The crystal shape of the phosphating film is determined by the composition of the phosphating solution and the fluidity of the phosphating agent, while the number of crystal nuclei formed at the initial stage of the phosphating reaction determines the crystal size. Nickel added in the phosphating solution can partially deposit on the surface of the substrate in the form of metallic nickel during the initial reaction of phosphating, forming a micro anode, which can effectively reduce the crystal size of the phosphating film. However, if the composi...
A brief analysis of ceramic chemical agent manufacturers What kind of packaging form does degreaser need? Now, each of our different chemicals has entered our lives. In many cases, our chemicals also need to be packaged. Moreover, since we entered the new society, which is the last stage of the development of our degreasing agent, when the modern degreasing agent manufacturers come into the field of degreasing agents, we have a new application for the use of such materials as degreasing agent materials.Moreover, for some degreaser materials, how to better develop the overall degreaser material market and the overall degreaser material economy is a very important issue. It is precisely because of this important issue that we can say in many different aspects that the use of these degreaser materials will require more different substances to have a better development and application conditions. Therefore, For the selection and purchase of plastic degreaser materials, it is better to choo...
According to the composition of degreasing agents, degreasing agents can be divided into three categories: first, organic degreasing agents, such as kerosene, gasoline, trichloroethylene, carbon tetrachloride and other degreasing agents. These degreasing agents are only crude degreasing agents, and cannot be directly plated after degreasing. The second type is water-based degreasing agent, which is composed of inorganic base, salt and surfactant. This kind of degreasing agent is the main body of electroplating degreasing agent. The third type is the mixed degreasing agent of inorganic and organic substances, also known as emulsion degreasing. It is mainly based on surfactant, adding kerosene or gasoline and water to form lotion, which is rarely used in production. In the process of electroplating, water-based degreasing agent is mostly used. It is composed of alkali metal hydroxide, carbonate, phosphate, silicate and surfactant. It is mainly used for chemical degrease, but also ...
