New Type Leakproof Chemical Resistant Chemical Liquid Pumps Electric Motor Driven
Product Description
The new carbon fiber composite material is our self-developed high-strength composite material, and has obtained national invention patent (patent number ZL201310597859.0, ZL201310343890.1). This material, based on carbon fiber and silicon carbide, with US imported special cross-linking agent, is made by chemically reacting at high temperature, and has extreme high corrosion resistance and wear resistance. The hardness of silicon carbide is almost as high as that of the diamond, so it has excellent wear resistance. Carbon fiber can improve the toughness of material to meet the flexural performance.

Cast Process Advantage
After studied the material properties, our company has found a special manufacturing process.
Thermal curing casting: The entire manufacturing process of DCS materials is carried out under vacuum and high temperature. The combination of coupling agent, tantalum carbide and carbon fiber is perfect.
Cold-cure casting: Some pumps may have voids, and then repair materials are essential to repair it. The method is cold-cure casting, but the material properties are far less than thermal curing.
Advantage
Comparison to Other Material
A contrast test between carbon fiber composite material and material 2507: under the same condition, medium: F, CI>800ppm, containing 12%sulfuric acid and 30%solid content, and its temperature is 90℃
1) Metal materials have relatively low corrosion resistance and wear resistance
2) Metallic overcurrent components not only have chemical corrosion, but also complex electrochemical corrosion.
3) All kinds of colloidal substances and chemical corrosion products in the medium are attached to the metal overcurrent parts. Due to the difference of the standard electrode potentials, the potential imbalance is formed. The solubility of the dissolved substances changes when the inlet pressure of the pump suddenly decreases. Then there is concentration differential galvanic cell, resulting in electrochemical corrosion. When the quality of the fluid is worse, the phenomenon is more serious.
4) New carbon fiber composite materials contain high-performance coupling agents with few free electrons on the surface, so there is no electrochemical corrosion.
5) New carbon fiber composite materials has extremely high hardness and has higher wear resistance than bidirectional stainless steel due to SiC
