Nano particle reinforced polymer element for stator and rotor assembly

A nano particle reinforced polymer element of a stator and rotor assembly for a power section of a positive displacement fluid motor or a progressive cavity pump. Nano-sized particles are blended with an uncured polymer to improve the physical and chemical properties of the polymer. The use of nano-sized particles reduces the quantity of reinforcement material required to manufacture the polymer for the stator and rotor assembly and lowers the viscosity of the uncured polymer to improve manufacturing characteristics. The use of chemically functionalized nano particles improves the chemical and physical characteristics of the polymer.

The invention relates to a high-strength aluminate silicate glass and a chemical toughening method thereof, and belongs to the silicate glass field. The glass comprises the following chemical components (weight percent): 55 to 65 weight percent of SiO2, 0.1 to 3 weight percent of B2O3, 6 to 24 weight percent of Al2O3, 3 to 9 weight percent of MgO plus CaO plus BaO plus SrO, 0 to 1 weight percent of ZrO2, 0 to 2 weight percent of ZnO, 0.1 to 0.5 weight percent of Cl2, 0.1 to 1.0 weight percent of Sb2O3, 0.1 to 0.5 weight percent of SO3 and 0.1 to 0.5 weight percent of F2, and belongs to a aluminate silicate glass system. The high-strength aluminate silicate glass is prepared through a known plate glass production method, and then is subjected to the strengthening treatment by adopting the chemical toughening method. The glass has high permeability of visible light, and relatively common soda lime glass, neutral medicine glass and alkali-free high-aluminum glass have good shock resistance property, high scratch resistance property and high durability. The high-strength aluminate silicate glass is applied to the screen surface protection of plasma display products and liquid crystal display products, the protection of touch screens, the screen protection of automated teller machines, and the screen protection of other electronic products (Mobile phones, PDAs and media machines, etc.), thereby effectively preventing the impact and the scratch damage to the glass surface of display products. The high-strength aluminate silicate glass contains no harmful elements.
