The present application relates to a kind of preparation methods of coating material, in particular to a kind of preparation methods of neodymium iron boron nano coating material.It includes the following steps: substrate pretreatment;Coating preparation: spray preparation nano coating, the binder of nano coating belongs to silicon-titanium modified polymer system, coating thickness is controlled at 20-25 μm, curing process: 50-70 ℃ surface dry 5-20 min, 160-200 ℃ baking and curing 40-60 min;Coating plasma treatment: plasma treatment 2-4 times.The present application nano gray coating can significantly improve surface tension after plasma treatment, the durability of coating surface tension treated under the condition that air is gas source is obviously superior to nitrogen, surface tension is still above 50 mN / m after room temperature is placed and naturally aged 6 months;After coating surface plasma treatment, drawing strength is also improved simultaneously.

The utility model provides a massage nozzle water outlet adjusting system, through the control panel control on -off of electromagnetic valve, can realize to the on -off of any one massage nozzle control, satisfy user's massage demand to different parts. Still through setting up the rotor with magnet in the water outlet pipe, make the rotor rotate under the water flow of water outlet pipe in the impulsion of the water flow and make the water outlet pipe form the rotating water flow and massage, simultaneously, through the hall sensor response magnet's magnetic field change to acquire the rotor speed, make the control panel according to each massage nozzle's rotor speed acquire corresponding water outlet speed, and then according to the water outlet speed control corresponding electromagnetic valve's on -off frequency to control the water flow size of water outlet pipe water outlet, thereby realize the control to each massage nozzle's water outlet water flow size and water pressure, and then adjust the massage strength of water flow, promote the massage effect, and satisfy and user's corresponding control demand to the water outlet of each position massage nozzle in the bathtub.

The utility model discloses a kind of farmland drip irrigation pressure regulating devices of high efficiency water-saving, including support base, the top of the support base is provided with water tank, the top of the water tank is provided with collection top plate, the top of the collection top plate is provided with power generation plate, the top of the support base is fixed with side baffle near water tank, the four corners of the side baffle are fixed with four groups of first slide bar, the top of four groups of the first slide bar is slidably connected with second slide bar, the top of the second slide bar is fixedly connected with the bottom of collection top plate, the inside of the water tank is fixed with first support column, the utility model, by setting pressure detection plate, the weight of water tank is detected, when liquid consumption in water tank, water tank weight also change, just can be detected by pressure detection plate Detect pressure to control electric telescopic rod, push water tank to move upwards, so increase the height of liquid can control outlet water pressure.

The utility model discloses a slag-flushing-controllable slag water quenching device which comprises a water quenching tank, splash-proof mechanisms are arranged on the two sides of the water quenching tank close to the upper portion, slag flushing mechanisms are arranged on the inner side and the outer side of the water quenching tank, a slag outlet is formed in the upper side of the water quenching tank, and three sets of supporting legs are arranged at the lower end of the water quenching tank. And the slag flushing mechanism comprises a blind plate fixedly arranged at the rear end of the water quenching tank, the rear end of the blind plate is fixedly connected with a connecting water tank, and two sets of first slurry pumps are fixedly installed at the rear end of the connecting water tank. According to the slag water quenching device capable of controlling slag flushing disclosed by the utility model, the pressure used by slag flushing water flow is controlled through the two groups of first slag slurry pumps, so that a plurality of groups of slag flushing ports connected with the two groups of second slag slurry pumps are used for flushing soaked slag possibly generated at the bottom of the water quenching tank in time, and the pressure of the water flow for flushing the slag is better controlled; and blockage of the inner side of the water quenching tank caused by dross due to improper water flow pressure is avoided.

The application discloses a catalyst preparation device for preparing ethylene through carbon dioxide assisted ethane dehydrogenation, and relates to the technical field of mixing equipment for preparing ethylene, which comprises a storage protection tank, a storage tank fixedly connected in the storage protection tank and the like. The catalyst preparation device for preparing ethylene through carbon dioxide assisted ethane dehydrogenation reflects sunlight through the storage protection tank, blocks the contact of external high temperature with the concentrated ammonia water, prevents the storage tank from being corroded by blocking sodium acetate through the first plastic inner wall, is convenient for being arranged above a reaction tank, controls the water pressure in the third installation pipe, controls the speed and intensity of water flow sprayed out of the third installation pipe by adjusting the water stirring intensity, using the centrifugal force to control the size of the hole area of the water spraying hole, and in this way, the mixed water with the concentrated ammonia water is sprayed farther, the concentrated ammonia water is distributed more uniformly, and the mixing effect is improved.
