The invention relates to an epoxy resin compound aqueous emulsion and discloses an epoxy resin compound aqueous emulsion which can be used for manufacturing glass fiber film-forming agent for wind turbine blades. The glass fiber prepared by the aqueous emulsion, being used as the film-forming agent, is particularly suitable for the preparation of the wind turbine blades, and the aqueous emulsion does not contain VOC (volatile organic compounds) and nonyl phenols surface active agents, thus the aqueous emulsion has good safety and environment-friendly performances. The epoxy resin compound aqueous emulsion is characterized in that the aqueous emulsion can be used as the film-forming agent to draw glass fiber for manufacturing the wind turbine blades, all the indications including the penetration velocity, the composite material performance and the like; the aqueous emulsion is well in storage stability and use stability and is safe and environment-friendly. The aqueous emulsion mainly comprises epoxy resin, an emulsifying agent and deionized water. The epoxy resin aqueous emulsion provided by the invention can be used for large-scale wiredrawing work by a tank furnace method, thus the process is stable and the manufacturing cost is low.

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. The cavitation bubbles generate local temperature and pressure diffusion at the moment of formation and collapse, and complete the synthesis of a highly stable hypochlorous acid solution. It can produce hypochlorous acid solution with high stability, improve the chemical performance stability of hypochlorous acid, improve the possibility of longer-term storage, and increase the application degree of hypochlorous acid.

The invention discloses a noodle maker convenient for operation. The noodle maker comprises a base, a stirring cup connected to the base and an upper cover covering the stirring cup. The noodle maker is provided with a stirring assembly and a dough extrusion assembly. The noodle maker is characterized in that the noodle maker comprises a weighing unit and a control unit for controlling the weighing unit, the noodle maker is provided with a protection structure, the protection structure is arranged at the weighing unit, and a safe stroke of the protection structure is less than a safe stroke of the weighing unit. The existing noodle maker is provided with the weighing unit so that a user can accurately control use amounts of flour and a liquid and the noodle maker normal-use is not influenced by inappropriate operation through a user. The noodle maker provided by the invention is provided with the control unit so that corresponding liquid weight can be automatically calculated after flour addition and the noodle maker gives a liquid weight prompt for the user and thus use operation is simplified.
