Slurry pump anti-corrosion and wear-resistant new materials

The metal is in a state of soaking or semi-soaking for a long period of time, which inevitably leads to metal corrosion. Corrosion of metal is a phenomenon in which metal is destroyed by chemical or electrochemical action of an environmental medium. The corrosion resistance and wear resistance on the slurry pump are the decisive factors for the service life of the slurry pump. As an example of a slurry pump applied to a mine, the primary working conditions of the ore are rather harsh. Therefore, in this section, the service life of the slurry pump is generally low. The service life of the slurry pump is very short and the replacement frequency is extremely fast. Today's latest valid order information is free! The latest buyer information in the morning is free! Crazy poke here grab grab! For a long time, people have been using a variety of technologies to protect metals from corrosion. Among them, one of the most effective and most commonly used methods for corrosion protection of metal equipment is to coat the metal surface with an anti-corrosion coating so as to isolate the corrosion medium from the metal substrate. Anti-corrosion coatings, like other coatings, consist primarily of base materials (resins), pigments, and solvents. The base resin is a film-forming substance, which is the main component in the coating. Its molecular structure determines the main performance of the coating. The pigment filler is used to assist in isolating the corrosion factors. This method not only has an impact on the environment, but also can not solve the erosion and wear problems of the slurry pump. Elastomeric polyurethanes have great advantages when applied to slurry pumps. Its high elongation and wide range of hardness; its wear resistance, biocompatibility and blood compatibility are particularly prominent. At the same time, it also has excellent oil resistance, impact resistance, low temperature resistance, radiation resistance and weight, heat insulation, insulation and other properties. Spray polyurethane has excellent properties such as wear resistance, water resistance, oil resistance, vibration absorption and noise reduction, high strength, and strong adhesion to metal, low noise, good self-cleaning effect, reduced wear of slurry pump, energy saving, and extended slag The life of the slurry pump can even increase the working efficiency of the slurry pump. This polyurethane elastomer material is almost the most non-metallic material that meets the requirements of the mine, and can even replace some of the metal material. Qinhuangdao Zhengmeihao Engineering Technology Co., Ltd. imported wear-resistant anti-corrosion polyurethane spray material from Canada. This material has good wear resistance and erosion resistance. What's more important is the superior performance of the matching adhesive. After a long time impact and mechanical action, it still has super adhesion to the surface of the substrate. It can handle the coating when the linear velocity of the part in the liquid or semi-liquid medium is less than 28.5m/s. In the above-mentioned complex and dynamic working environment, the development prospects are very broad. This wear-resistant coating has a large span of Shore hardness. From Shaw A45 to Shore D60. The hardness can be adjusted according to different working conditions, the content of polar groups can be increased, the hydrogen bonds can be fully utilized to increase intermolecular forces, and the effective coating time can be effectively extended. In addition, this material not only can effectively resist erosion and cavitation wear, but also can withstand strong acid and alkali corrosion in the range of 3-11 pH. This material not only protects the surface from water erosion, cavitation wear, but also protects parts from acid and alkali corrosion. It is a truly versatile surface treatment material. This type of material is universally strong and widely used in various industrial fields where it is necessary to provide corrosion protection and wear protection, and has achieved good results. Facts have proved that this kind of material has a very strong bond with the substrate, and the life of the coating is generally more than ten times higher than that of ordinary metal materials. The economic benefits are quite significant.
