wear solution to mining site

Carbon steel, low-alloy steels have poor resistance to erosion, cavitation and corrosion, so hydraulic components made from these materials have lower lifetimes. Although stainless steel impeller corrosion resistance, cavitation erosion better performance, but due to erosion of sediment wear and tear, running 15kh must be overhauled. At present, the low-carbon martensitic stainless steel widely used both at home and abroad is a material with better anti-cavitation ability, but its brittleness is big and the welding performance is poor. In the multi-silt rivers, this series of materials is still difficult to meet the requirements of over-current components Erosion wear requirements. This advanced polymer material is a composite material prepared from polyurethane elastomer and epoxy resin. It is attracting more and more attentions in the field of slurry erosion wear and corrosion wear. More importantly, the adhesive with the performance superior. After being subjected to long-term impact and mechanical action, it still has the super-adhesion ability to the substrate surface and can be used in the complex dynamic working environment such as high specific strength, fatigue resistance, impact resistance and chemical corrosion resistance The development prospect is very broad. Shore hardness of this wear-resistant coating spans large. From Shore A45 to Shore D60. According to the different conditions of the environment to adjust the hardness, increase the content of polar groups, make full use of hydrogen bonds to enhance the intermolecular force, effectively extend the coating effective time. In addition, this material not only can effectively resist cavitation wear, but also can withstand pH 3-11 pH range of strong acid, alkali corrosion. This kind of material is versatile and widely used in various industrial fields that need to provide anti-corrosion and wear-resistant protection and has achieved good results. Facts have proved that the combination of this material and the substrate is very strong, the coating life is generally ten times more than ordinary metal materials, the economic benefits are quite significant.
