The utility model belongs to the technical field of quenching tube furnaces, and particularly relates to an in-situ atmosphere quenching tube furnace and a quenching method thereof. The in-situ atmosphere quenching tube furnace comprises a high-temperature furnace body, a furnace tube penetrates through the high-temperature furnace body, the front end of the furnace tube is connected with a T-shaped tee joint, a sample groove with a long handle is formed in the T-shaped tee joint in the horizontal direction, the T-shaped tee joint is an air inlet end in the vertical direction, a quenching pool connector is vertically formed in the rear portion of the furnace tube, and a quenching pool is arranged in the quenching pool connector. A quenching pool is connected below the quenching pool connector, the rear end of the furnace tube is an air outlet end, and the air outlet end is connected with a hose. Through a full-sealed operation chain and precise time sequence control, full-flow atmosphere protection from high-temperature treatment to ultra-fast cooling of the nano material is realized, grain boundary oxidation and element segregation are effectively inhibited, quenching treatment of materials extremely sensitive to oxygen, water and carbon dioxide is supported, and the service life of the nano material is prolonged. The problem of material decomposition caused by temporary air exposure of traditional open or semi-closed equipment is solved.

This invention provides a dressing containing Ligusticum striatum microspheres and its preparation method, to solve the problem of safe and precise application of Ligusticum striatum extract or Ligustrazine in difficult-to-heal wounds; the dressing containing Ligusticum striatum microspheres and its preparation method, wherein the dressing is composed of Ligusticum striatum microspheres loaded with pHEMA hydrogel as the main body, wherein the Ligusticum striatum microspheres are formed by coating Ligusticum striatum extract or Ligustrazine with PLGA, and the pHEMA hydrogel partially encapsulates the Ligusticum striatum microspheres.

The invention discloses a frozen film concentration device and belongs to the technical field of vacuum concentration. The invention solves the problem that the product quality is easy to decline because the feed liquid needs to be continuously heated in the existing vacuum evaporation and concentration operation process. A refrigerant inlet is formed in the top of the rotor, a refrigerant outlet is formed in the bottom of the rotor, the top of the rotor is connected into the liquid collecting disc and rotates along the central axis of the liquid collecting disc, and a plurality of overflow holes are formed in a first area of the side wall of the liquid collecting disc. A scraping plate is fixedly connected to the side wall, far away from the first area, of the concentrator shell, and the other end of the scraping plate is tightly pressed on the side wall of the rotor. Refrigerant flows in the rotor, so that the surface of the rotor is kept in a low-temperature frozen state, a plurality of frozen film concentrators are connected in series to form a multi-stage continuous concentration process, the whole concentration process is performed in a low-temperature environment, original nutritional ingredients of feed liquid are reserved to the greatest extent, and the quality of concentrated products is greatly improved.

The invention provides a compound sodium nitrophenolate-thidiazuron microemulsion and a preparation method thereof. The microemulsion comprises an effective component, a high-molecular long-chain EO-PO polymer and an auxiliary material part, wherein the high-molecular long-chain EO-PO polymer comprises a polymer with the molar molecular weight of 5000-30000. According to the invention, a high-molecular polymer is creatively used for coating a thidiazuron active compound in a nanoscale micro-droplet state, so that the problem that thidiazuron is greatly decomposed after the thidiazuron active compound and compound sodium nitrophenolate are compounded to prepare the microemulsion is solved; meanwhile, the high-molecular polymer disclosed by the invention replaces a traditional solvent dissolution form with a form of wrapping a thidiazuron active compound, so that a slow-release effect is achieved, the long-acting property of the whole preparation is improved, the medication frequency and the dosage are less, meanwhile, the high-molecular polymer is safe to crops, the plant vigor is improved, the fruit setting rate can be remarkably increased, and the stress resistance of plants is enhanced.
