Disclosed is a Ni-based single crystal superalloy having a composition consisting of, in mass percent, 5.0-7.0% of Al, 4.0-8.0% of Ta, 0-2.0% of Mo, 3.0-8.0% of W, 3.0-8.0% of Re, 0-0.50% of Hf, 3.0-6.0% of Cr, 0-9.9% of Co, 1.0-14.0% of Ru, 0.1-4.0% of Nb and the balance of Ni and unavoidable impurities. The present invention provides a Ni-based single crystal superalloy which suppresses the precipitation of the TCP phase at high temperatures, improves strength at high temperatures, and has oxidation resistance at high temperatures. The inventon aims to provide a Ni-based single crystal superalloy of high performance in strength and oxidation resistance at high temperatures, and further aims to provide a Ni-based single crystal superalloy having sufficient characteristic in a ''heat treatment window'' of not being negligent at the practical aspect.

The invention discloses a magnetic suspension thermobalance measurement method based on rapid photothermal heating. The method comprises the following steps: 1) weighing and taking a measurement material into a reaction tank; 2) placing the reaction tank into a closed container together with a magnetic suspension float; 3) suspending a magnetic suspension float in the closed container by a magnetic suspension device; 4) introducing a gas into the closed container; 5) measuring the real-time position of the magnetic suspension float by a laser displacement monitoring assembly, and adjusting theposition of a magnetic suspension stator to suspend the magnetic suspension float to a measurement zero position; 6) heating the reaction tank by photothermal heating assemblies; 7) adjusting the positions of the photothermal heating assemblies to maintain a heating beam on the reaction tank; 8) measuring the temperature of the measurement material in the reaction tank; and 9) recording the displacement of the magnetic suspension float, and converting the displacement into mass. The displacement of the magnetic suspension float is measured, and is converted into material mass change, so the systematic error is reduced, and high-precision measurement of the material mass change under a temperature control condition is achieved.

The present invention relates to a method for manufacturing a handle for a hand tool, the handle comprising a body portion and a gripping part that is provided at least partly on the body portion and intended for the user to grip when using the hand tool. In the method of the invention there is first fabricated the gripping part and it is set in a mould cavity, whereafter melt mass is cast into the mould cavity to provide the body portion such that the melt mass flows underneath the gripping part, whereby the gripping part is pressed against the wall of the mould cavity.

The invention provides the preparation and application of a rapid film-forming energy-saving and environmental protection machine spray fine decoration mortar. The preparation method is: mixing the solid phase change material and the liquid phase change material, heating and melting, adding antioxidants and adsorption materials, and after the adsorption is saturated, Mix evenly with thermal conductivity additives and film-forming agents, solidify and form, cool to room temperature, and obtain solid-liquid phase change materials; white cement, diatomaceous earth, emulsifier, epoxidized polybutadiene, gypsum and solid-liquid phase change materials The materials are added into water, mixed evenly, cured and molded, removed from the mold, and cured for 28 days to obtain fast film-forming energy-saving and environmental protection machine spray fine decoration mortar. The refined decoration mortar prepared by the invention has high content of phase-changing materials, excellent energy storage effect, good thermal conductivity, good dispersion with mortar, good constant temperature effect, and rapid film-forming performance of epoxy-modified polybutadiene polymer Excellent, also has waterproof and anti-corrosion, therefore, the refined decoration mortar prepared by the present invention is green and constant temperature, energy-saving and durable, safe and environment-friendly.

The invention relates to a method for reducing the content of heavy metal ions such as arsenic and lead in instant tea. The tea leaves are extracted, centrifuged, filtered, concentrated and other processes are prepared into a concentrated solution with a mass concentration of 5-15%, and the concentrated solution is passed through the LX The resin column of ‑8 macroporous adsorption resin adsorbs tea polyphenols, and then passes the column liquid through the resin column filled with chelating resin LSA‑100 to adsorb heavy metal ions such as arsenic and lead, and collects the eluate of LX‑8 resin and LSA ‑100 resin column solution, mixed evenly, then concentrated and dried to prepare instant tea powder with low heavy metal content. The removal rate of heavy metal ions such as arsenic and lead in the instant tea powder obtained by the treatment of the present invention reaches 50%, the loss rate of tea polyphenols is less than 5%, the operation is simple, and the prepared product retains the original quality of instant tea to the greatest extent. The heavy metal removal effect is obvious, breaking through the raw material limitation of instant tea production, expanding the range of raw material selection, and improving the safety and market competitiveness of instant tea products.

The present invention relates to a method and an arrangement for measuring the smoothness of grains. In one embodiment, the arrangement includes a channel for supplying grains, especially rice grains, an obstacle arranged at the channel to slow down grains falling on the obstacle, so that the flow of grains forms a heap on the obstacle and an image capturing device placed facing the obstacle. The image capturing device is arranged to capture an image of the heap, where the area under the curve of the captured heap image indicates the degree of smoothness of the grains or the course of the curve of the captured heap image indicates the degree of smoothness of the grains.

The invention discloses a method for treating cut stems that can improve the whiteness of cigarette ashes. The method comprises the following steps: (1) eluting cut stems; (2) using a repairing agent to repair the washed cut stems to restore Cut stems are resistant to processing strength, enabling them to be smoothly incorporated into cigarettes during normal cigarette production. After the shredded stems treated by the invention are added to cigarettes for use, the ash whiteness of the cigarettes can be improved by 15-30 units, the tuff index can be reduced by 1-2 units, and the sensory quality of the cigarettes changes little, and there is no potential safety hazard.
