A preparation method of neodymium iron boron magnet is disclosed. The composition general formula of the magnet provided by the invention is R1R2FeMB, wherein R1 is at least one element selected from the group consisting of Nd, Pr, La, Ce, Sm, Sc, Y and Eu, having a content of 23 to 35 wt%; R2 is at least one element selected from the group consisting of Tb, Dy, Gd, and Ho, having a content of 0.1 to 5 wt%; M represents transition group metal with the exception of Fe, having the content of 0.01 to 5 wt%; B represents simple substance boron, having the content of 0.8 to 1.2 wt%; the balance isFe and the other inevitable impurities. The preparation method of neodymium iron boron magnet provided by the invention works in such a manner that: one or more elements in the R2 are plated to the surface of the magnet, the metal R2 is diffused into the interior of the magnet by primary high temperature heat treatment, and imbalance organization and internal stress brought by the high temperature treatment are eliminated through secondary low temperature tempering. Low temperature molten salt electrodeposition method is employed to plate films. The present invention is advantageous in greatly improving the production efficiency, reducing the dosage of the heavy rare earth during preparation process of magnet, saving rare earth resource, and obtaining high coercivity without reducing remanent magnetism and magnetic energy product of a magnet.

The invention relates to the field of cloth processing, and discloses a dyeing method for cloth. The method comprises the steps that dye raw materials are prepared; an unwinding roll, a winding roll,an outer tube, an inner tube, a drying mechanism and a water inlet pipe are prepared; dye B is prepared; gray cloth is coaxially installed on the unwinding roll, and one end of the gray cloth penetrates through a second inlet, a dye cavity, a first inlet, a first outlet and a second outlet in sequence and then fixedly connected to the surface of the winding roll; meanwhile, and the dye B is pouredinto the dye cavity through the water inlet pipe; the winding roll rotates at the rotating speed being 10-20 r / min, at the moment, the gray cloth penetrates through the second inlet and is located atthe dye cavity, the dye B in the dye cavity dyes the gray cloth, and gray cloth A is obtained; the gray cloth A continues to move to pass through the first inlet and the first outlet and is located at the drying mechanism, the drying mechanism dries the gray cloth A, and gray cloth B is obtained, wherein the baking temperature of the drying mechanism on the gray cloth A is 100-200 DEG C; the graycloth B continues to move to pass through the second outlet and then is wound on the winding roll. Accordingly, corrugation generated on the cloth in the dyeing process can be avoided.

The invention relates to a detection method of pterocephalus hookeri. The detection method is capable of simultaneously detecting loganin, ursolic acid and / or oleanolic acid in pterocephalus hookeri. The separation and content measurement of loganin, ursolic acid and / or oleanolic acid in great polarity difference can be realized by virtue of the simple gradient variation of the flow phase, and the real detection requirement can be further met.

The invention provides a compensation type micro-control solenoid valve which is composed of a main driving coil, a motion compensation coil, a fixed iron core, a movable iron core, a control circuit and the like. The motion compensation coil and the main driving coil are arranged in parallel; the control circuit controls the motion compensation coil to carry out demagnetization operation; the fixed iron core and the movable iron core are located in the coil; the fixed iron core is fixed with a fixed shell through a locking screw; the movable iron core is located below the fixed iron core; a reed and a membrane are fixed on the movable iron core through a pressing screw; a screw head of the pressing screw is located between the membrane and the reed; a magnetic conduction seat is mounted at the lower end of the shell and the magnetic conduction seat is provided with clamping positions which correspond to the reed and the membrane; the clamping position matched with the membrane is a sealing clamping position. The compensation type micro-control solenoid valve forcedly eliminates the disaster result caused by residual magnetism of a flexible magnetic material of an electromagnetic adjusting valve. The control precision, the flexibility and the stability of the electromagnetic adjusting valve are improved. A stainless steel membrane and a non-linear elastic property reed are adopted, and a resistance vibration-absorption hole is innovatively arranged, so that the influences on controlling the solenoid valve by backpressure fluctuation are greatly reduced.

The invention discloses a hypochlorous acid production system and a high-stability hypochlorous acid production method, comprising a raw material input device, a liquid outlet system, an electrolysis module and an ultrasonic vibrator, the electrolysis module includes an electrolysis cell and an electrolysis power supply, and the ultrasonic vibrator Set in the electrolytic cell of the electrolysis module, the electrolysis module is used to electrolyze the mixed solution of sodium chloride solution and pure water to generate chlorine gas; the ultrasonic vibrator is used to use ultrasonic vibration to make the chlorine gas generated by the electrolysis module form nano-scale cavitation bubbles; At the moment when the cavitation bubbles are broken, the ultrasonic vibration is used to synthesize and break the bubbles again.
