2 results about "Microwave power" patented technology

The invention discloses a preparation method of a feed additive, and a feed additive prepared by adopting the preparation method. The preparation method of the feed additive comprises the following steps of extracting wood cellulose from natural logs; performing microwave treatment on the extracted wood fiber, wherein the microwave treatment is carried out at a microwave power of 5-20kW for 20-80seconds; performing quick-freezing on the treated wood fiber at -40 DEG C to -10 DEG C for 20-50 minutes, taking the quick-frozen wood fiber out, and immediately performing heating on the wood fiber by using high-pressure water vapor for 5-30 minutes, wherein the high pressure is 2-5MPa and the heating temperature is 160-290 DEG C; repeating the quick-freezing and heating operations for 1-3 times;performing ultrasonic treatment on the processed wood fiber at 20-50 DEG C for 10-30 minutes; and then, washing the ultrasound-treated wood fiber, carrying out filtrating and drying, and grinding thedried wood fiber into fine particles used as raw materials or one of the raw materials of the feed additive. The feed additive prepared by the preparation method disclosed by the invention is high incrude fiber content, and capable of improving intestinal health of livestock and poultry; moreover, the feed additive is low in addition amount so that no formula space is occupied.

The invention relates to the technical field of new materials, and particularly relates to a color film. A preparation method comprises the following steps: providing an aluminium substrate; forming alayer of base film on the surface of the aluminium substrate by means of anode oxidation coloring; and charging the mixed gas of methane, hydrogen and oxygen into a reaction cavity by means of microwave plasma chemical vapor deposition, selecting a solid microwave source with a microwave frequency of 915MHz, setting a temperature to be 400 DEG C, setting a microwave power to be 1.5kw-4kw, settingan atmospheric pressure to be 20-45mbar, and forming a diamond-like carbon film on the surface of the base film as a protection layer. According to the color film disclosed by the invention, the hardness of the color film is increased and the durability of the color film is improved through forming the hydrophilic/ hydrophobic diamond-like carbon film on the existing color film, and the color film is high in applicability.
