Pulp pump wear, corrosion and scouring are common faults of the equipment. How to improve the production efficiency and efficiency of the equipment is one of the important prerequisites for enterprises to improve their profitability.

In view of the problem of wear and corrosion of sewage pumps, frequent replacement of equipment components is currently the method commonly used by enterprises, and the equipment is affected by materials and processing techniques, and has a high universal value. For example, high-value metal materials such as glass-lined equipment, polytetrafluoroethylene parts, and titanium materials. Brush plating and spray re-machining methods often require external support. Not only the repair cycle is long, the cost is high, but also the repaired materials or metal materials cannot fundamentally solve the cause of wear (metal impact resistance and poor concession). ); many components can only be scrapped and replaced, which greatly increases production costs and spare parts, so that the company's good resource advantages are idle and wasted.

Surface adhesion protection is widely used in abrasion, cavitation, corrosion repair and pre-protection coatings. It has good chemical resistance and excellent mechanical properties and bonding properties. Compared with the traditional pressure vessel welding repair, it has the characteristics of simple construction, low cost, safe performance and good repair effect. Carbon nano-polymer repair technology is a relatively mature and cost-effective maintenance solution. Short time, low cost and good effect are some of the main features of the technology. Carbon nano-polymer technology is a high-performance epoxy two-component composite reinforced by nano-inorganic materials and carbon nanotubes. The biggest advantage of this material is that it uses special nano-inorganic materials to bond with the oxygen of epoxy ring molecules to improve the bonding force between molecules, thereby greatly improving the overall performance of the material, and it can adhere well to various metals, concrete, Glass, plastic, rubber and other materials. The material not only has good water resistance, corrosion resistance, abrasion resistance, cavitation resistance, etc., but also the high-gloss mirror advantage of the material can greatly improve the performance (5-8%) after being applied on the fluid equipment, thereby reducing energy consumption.
