High temperature-resistant anti-oxidation filter material and manufacturing method thereof

The invention relates to a high temperature-resistant anti-oxidation filter material and a manufacturing method thereof, belonging to the technical field of high-temperature filter materials. 1%-10% of 2,5-di-tert-butylhydroquinone or rosemary antioxidant liquid is utilized for performing impregnation or coating treatment on a 300-1000g/square meter filter felt produced by the needle puncture method or the spunlacing method for coating an anti-oxidation coating layer with 0.5-50 microns on the surface of the filter felt, and then high-temperature baking treatment and thermosetting with steam or hot oil are performed for 1-60 minutes at the temperature of 100-235 DEG C for forming the high temperature-resistant anti-oxidation filter material for filtering high-temperature smoke dust. In order to solve the defects of the filter material for a bag dust collector in the anti-oxidation aspect, the invention provides the high temperature-resistant anti-oxidation filter material and the manufacturing method thereof, by using the high-temperature antioxidant to perform the impregnation or the coating on the filter material and further performing the baking and the thermosetting treatment,the filter material has the anti-oxidation property, and the too early aging failure of the filter material under a high-temperature oxidation environment can be avoided.

ActiveCN102504383ARetains antioxidant propertiesReduce aging speedCovering/liningsLaminationThermoplasticFluidized bed
The invention provides a substrate layer prepared from dry desulfurized ash for a reinforced board. The preparation raw materials comprise the following components by weight percent: 61%-81% of dry desulfurized ash, 18%-38% of thermoplastic plastic and 0.7%-1% of coupling agent. The invention also provides an aldehyde-free reinforced board containing the substrate layer and a wear-resisting layer. The preparation method of the substrate layer for the reinforced board comprises the following steps of: a) carrying out thermal treatment on the dry desulfurized ash by using a circulating fluidized bed process; b) mixing the coupling agent with the dry desulfurized ash subjected to thermal treatment, heating and stirring, then adding the thermoplastic plastic, and stirring; and c) extruding and pelleting the prepared mixture, and carrying out mould pressing or extrusion molding in a flat extruder after pelleting. The prepared aldehyde-free reinforced board does not release harmful aldehydegases, and has the characteristics of oxidation resistance, ageing resistance, watertightness, mildew resistance and warping resistance; and in the production process, secondary pollution is not generated, and wood does not need to be used, thus the production process is environment-friendly and energy-saving, and the standard requirement of a reinforced board industry is reached.

Method for manufacturing terahertz quantum cascade laser metal waveguide structure and laser

The invention discloses a method for manufacturing a terahertz quantum cascade laser (QCL) metal waveguide structure and a laser. The method comprises the following steps of: successively growing an etching stop layer, a lower contact layer, a multi-quantum well active region, an upper contact layer, an n-type heavily doped layer, and a low-temperature growth passivation layer on a semi-insulating GaAs substrate by using molecular beam epitaxy; forming non-alloy ohmic contact; successively depositing an electrical contact enhancing metal layer, a metal In layer and a metal Au layer on a receiver substrate; performing flip-chip bonding on a device substrate and the receiver substrate, depositing a SiO2 protective layer, applying photoresist, and baking the photoresist; stripping off the photoresist; removing the SiO2 protective layer; forming a Schottky diode to contact a upper electrode metal layer; forming a lower electrode metal layer; performing flip-chip bonding substrate cleavage and packaging. The method reduces contact resistance, avoids the large free carrier leakage of a terahertz photoelectric device caused by the diffusion of the uncontrolled doping distribution, and reduces a waveguide loss caused by a annealing process.

Purpose of pig placenta freeze-dried powder in resisting oxidation

The invention belongs to the technical field of food processing and particularly relates to a purpose of pig placenta freeze-dried powder in resisting oxidation. Based on the problem that the pig placenta freeze-dried powder is not applied to skin oxidation resistance in the prior art, the invention provides a purpose of applying the pig placenta freeze-dried powder to prepare a skin care product resisting skin aging. A preparation method of the pig placenta freeze-dried powder comprises: (a) taking a pig placenta frozen at (-50)-(-30) DEG C, and unfreezing at 4-10 DEG C; (b) crushing the pig placenta with a high-speed tissue mashing machine, pouring into a freeze drying tray, and performing first time of freeze drying; (c) after the step (b) is completed, turning over the pig placenta entirely in the freeze drying tray, and performing second time of freeze drying; (d) putting the pig placenta dried in the step (c) into an aluminum foil bag, vacuumizing, and storing at 4 DEG C for later use. The method is easy to operate and can maintain the nutritional ingredients and antioxidant active ingredients in the pig placenta to the greatest extent; the prepared pig placenta freeze-dried powder has an oxidation resisting function and has important economic benefits.
