Chapter 796 Electrolysis

Previous page        Return to Catalog        Next page

    After breakfast, the three of them moved to the desk.  Mr. Zhao explained the design principles to the two disciples based on the design drawings he had worked on overnight.

    In fact, the disciples who designed the structure already had a plan in mind. All Mr. Zhao could do was remind them of some design points to avoid taking detours.

    For example, it is best to add an appropriate amount of electrolyte to the water to enhance the conductivity of the water and speed up the reaction.

    For example, the reaction rod inserted into the water is best to be an inert electrode, such as a carbon rod, rather than a metal rod.  Because electrolysis is a strong redox reaction, metals will participate in the reaction.

    And the carbon rod is best made into a hook shape, which can facilitate the bamboo tube to collect gas

    After listening to the key points introduced by the master, Zhao Shizhen and Zhang Jian spent an hour breaking down the sketch into parts drawings and giving the specifications of each part.

    Looking at the stack of drawings that resembled standardized drawings in front of him, Mr. Zhao couldn¡¯t help but sigh secretly, maybe this is the gap between geniuses and mortals.

    He became more and more determined to do his best in the future. Only by hiding his clumsiness can he keep his foolishness.

    The head can be cut off and the blood can be shed, but Teacher Zhao¡¯s glorious image cannot be lost!

    ??~~

    Mr. Zhao sent people to the county to collect relevant materials last night.

    Fortunately, the materials needed were not rare. When they completed the drawings, Xiwa came to report that they had everything.

    They took the drawings and materials to Jiangnan Hospital and occupied a medical laboratory.

    The first step is to make enameled wire. With enameled wire, coils can be wound to produce electromagnetic effects.

    Enameled wire is composed of conductors and insulation layers.

    Generally, the wires are made of copper, but Mr. Zhao could not find such a thin copper wire at the moment.

    Fortunately, Daming¡¯s high-end embroidery used a large amount of gold and silver thread fabrics.  Therefore, even in Kunshan there are shops that specialize in making gold and silver threads. They have all kinds of gold, silver, round and flat ones.

    Mr. Zhao finally chose silver wire because silver has the best conductivity, so he was reluctant to use gold wire.

    As for the insulation layer, it is a little more troublesome. Mr. Zhao has not yet lit up the technology tree of resin materials, so he can only use the oldest oil-based enameled wire which is to repeatedly brush tung oil on the wire.

    However, the wear resistance is too poor and cannot be used directly for winding. A good fine cotton yarn wrapping layer must be used.

    This is what Faraday used.

    This is a delicate job. Not to mention Mr. Zhao, even the two inventors with their dexterous hands couldn't do it well at first.

    Fortunately, the surgical master Li Lunming is here. Director Li's hands are really more skillful than Xiu Niang's.

    ¡°I saw him pulling out the slender silver wire from the coil, quenching and baking it until soft, and then using a brush smaller than a toothbrush to carefully paint the silver wire with tung paint.

    Then put the painted silver wire on a copper fire plate covered with a thick cloth and slowly dry it.

    After drying, brush with tung oil again and dry again.  If you do this three times, you can wrap the cotton yarn.

    ??~~

    In that room, the two inventors were not idle either.

    Zhang Jian is making a wooden box and a square wooden frame according to the drawing.

    Zhao Shizhen took apart several lead-chisel pen cores, mashed them together with bamboo charcoal, sieved them, and then used an appropriate amount of fish bladder glue as a binder to make a curved umbrella handle-shaped rod blank.

    After drying, it is put into the boiler and baked at high temperature for a long time to form a ceramic-like texture, and it is ready for use.

    Fortunately, the hospital has a boiler room with a bellows, otherwise it would be really difficult.

    ??~~

    In the afternoon, the enameled wire production was completed.

    Under the command of Mr. Zhao, Li Lunming evenly wrapped the wires around the outside of the square wooden frame, wrapping each turn very tightly.

    Zhao Hao took the wooden frame from his hand and nodded with satisfaction: "It's like a work of art. Director Li is really good at his craftsmanship."

    "Can this thing generate electricity?" Li Lunming looked in disbelief.  He always felt that that was something only the Thunder God and the Lightning Girl could do.

    ???????? Mr. Zhao, who has already brought many miracles, if someone else tells him that he can use this bunch of simple things to generate electricity, he will definitely scold his mother.

    "Let me open your eyes!" Zhao Hao ordered, and Zhang Jian held a wooden box and placed it on the table.

    Li Lunming only saw an iron shaft with a rocking handle in the wooden box, and a stone the size of a paperweight was tied to the iron shaft.

    This is of course not the best design, but the simplest verification design to make.

    Time is life.

    Zhang Jian took the wooden frame and put it into the box.

      With a snap, it was stuck tightly in the notch reserved on the inner wall of the wooden box The craftsmanship of inventors in this era was his best.

    You can¡¯t become an inventor without skills.

    Then he picked up a bowl of lard and used a brush to apply a layer of oil to the iron shaft and wooden holes to lubricate it.

    At the same time, Zhao Shizhen led the two ends of the silver wire from the small holes reserved at both ends of the wooden frame and wrapped it around two carbon rods as thick as chopsticks.

    "Close the curtains!" Mr. Zhao ordered and put on the thick rubber gloves of Eucommia ulmoides, his heart pounding with excitement.  He secretly said that I haven't built a steam engine yet, but I should build a generator first.

    "Shake it up!" Zhao Hao ordered loudly.

    Zhao Shizhen also wore gloves and slowly turned the handle of the iron shaft. The stone tied to the iron shaft began to rotate slowly.

    ¡°It¡¯s time to witness the miracle!¡± In the dim room, Zhao Hao held up a carbon rod in one hand and slowly approached it.

    Everyone stared wide-eyed and held their breath, not knowing what would happen next moment.

    Just when the two carbon rods were still an inch apart, a blue electric spark suddenly appeared between the two rod tips, shocking everyone present!

    "Success!" Zhao Shizhen and Zhang Jian cheered.

    But the two of them were not too excited.  Because at this time, they still don't know what this arc means to human beings.

    "Lightning!" Li Lunming immediately knelt on the ground, shocked beyond measure: "Young master actually created lightning!"

    ?????????????????????????????????????????????????????:???????He actually bowed to Zhao Hao and worshiped: "No wonder the young master is so miraculous, it turns out that it is Lord Thunder who descended to earth!"

    "I'm still a mother of lightning. Get up quickly and don't embarrass yourself." Zhao Hao rolled his eyes and didn't argue with him.

    Because Mr. Zhao is in a good mood at this moment, the world's first DC generator was born in his hands.

    Sorry, Comrade Xiaofa.  From now on, the unit of capacitance will be ¡®Zhao¡¯¡­

    Uh, so ugly, let's talk about it later.

    ??~~

    After testing that the hand-operated generator was working normally, Mr. Zhao struck while the iron was hot and asked the guards to open the curtains and bring up a water tank.

    There was warm boiling water in the tank. Mr. Zhao put on a mask and gave instructions from the side.

    Zhang Jian carefully added Glauber's salt into it, and Zhao Shizhen stirred it slowly with a wooden stick.

    Wait until precipitation gradually appears in the water and the water temperature has completely cooled, then ladle the water into a porcelain basin.

    ?The two carbon rods were fixed on a thin wooden board and sent into the basin with their big ends facing down, just like fishing.

    Then put the two bamboo tubes on the two carbon hooks, put a pig urine bubble on each end of the bamboo tube, and tie them tightly with a rope.

    When the crank handle of the generator is cranked, a slight gurgling sound soon comes out of the bamboo tube, like water boiling.

    The two deflated pig urine bubbles gradually filled up.

    ?The one on the left obviously inflates much faster and generates strong lift.  If Zhao Hao hadn't pressed down in time, he would have made the thin wooden board hanging on the edge of the basin fly up.

    The three masters and apprentices laughed happily, knowing that the electrolysis was successful.

    ps. We are collecting the names of the Ming Dynasty versions of the seven major units of measurement.  Let¡¯s start with length today.

    If you agree to use the current feet, feet, and inches, please choose 1. If you agree to change to the metric system, please choose 2 (of course, it does not necessarily need to be called meters or centimeters).

    The voting period is three days.
