Abstract: A three-stage degassing and dewatering device includes a first-stage degasser, a second-stage degasser, an oil drainer, a rod electrode, a dewaterer, and a water drainer. The first-stage degasser implements a first-stage axial-flow type collision buffer degassing and dewatering operation, forming a first-stage crude oil after removing some of the gas and water in the gas-containing and water-containing crude oil. The second-stage degasser implements a second-stage elevated efficient degassing operation, forming a second-stage crude oil after removing the remaining gas in the first-stage crude oil. The rod electrode constructs a dynamic electric field with a high frequency and a high voltage, and implements a third-stage high-frequency and high-voltage rapid dewatering operation together with the dewaterer, forming a qualified crude oil after removing the remaining water in the crude oil emulsion.

Abstract: A preparation method includes 1) dispersing cellulose nanocrystal in water and adjusting pH to 7; 2) adding carboxylate to the aqueous dispersion of the step 1), and stirring until uniform; and 3) adding a monomer and a ceric ammonium nitrate initiator to the system of the step 2), reacting for 0.5-3 h to obtain a precipitate, and subjecting the precipitate to suction filtration, washing, and drying to obtain the cellulose nanocrystal powder. By adding a small amount of carboxylate into a cellulose nanocrystal graft polymer modification system initiated by ceric ammonium nitrate, hydrolysis of cerium ions can be inhibited through complexation of the carboxylate to the cerium ions which play an initiating role in ceric ammonium nitrate, so that ceric ammonium nitrate can initiate the polymerization reaction under acid-free conditions, thereby achieving polymerization of polyvinyl acetate monomer on the surface of cellulose nanocrystals.

Abstract: A method and apparatus for mass production of AR diffractive waveguides. Low-cost mass production of large-area AR diffractive waveguides (slanted surface-relief gratings) of any shape. Uses two-photon polymerization micro-nano 3D printing to realize manufacturing of slanted grating large-area masters of any shape (thereby solving the problem about manufacturing of slanted grating masters of any shape on the one hand, realizing direct manufacturing of large-size wafer-level masters on the other hand, and also having the advantages of low manufacturing cost and high production efficiency). Composite nanoimprint lithography technology is employed (in combination with the peculiar imprint technique and the composite soft mold suitable for slanted gratings) to solve the problem that a large-slanting-angle large-slot-depth slanted grating cannot be demolded and thus cannot be manufactured, and realize the manufacturing of the slanted grating without constraints (geometric shape and size).
