The raw lacquer cut from the lacquer tree is almost flat and is not afraid of any corrosion. [Read the latest chapter] Whether it is water, strong enemies, or flying alkali, Lingao does not produce sumac trees, but there are many in Guangdong. The Industrial Energy Commission imported some, and Xu Yingjie prepared a large water tank. After making it thick enough, he soaked straw ropes in it to replace asbestos ropes and water glass. However, he also paid the price. Even though he took full body protection, he still got "paint bites" on his hands. My fingers were swollen and I had to rest for several days.
Ji Situi randomly picked up a jar and tried the threaded lid: "This jar is good. We need to maintain long-term production. In the future, there will be a huge demand for sulfuric acid, nitric acid, and hydrochloric acid." Chemicals. "Ji Situi said, "I still have an order. It's equipment for the chemical industry. You should quickly organize people to make it. "
"Do you still have to do it?" Xiao Bailang complained, "I haven't had a good night's sleep in three or four days. There are only a dozen workers in the ceramics factory. This is too much work!" He took the list and listed it. There are more than thirty water jars of various sizes, as well as some other ceramics.
"Making a water tank like this! Do you want to make pickles?"
"It must have something to do with salt," Ji Situi said. "It's all used in engineering. Hurry up."
"Then please give me some overtime pay. The ceramic craftsmen here have been busy day and night recently.
"You ask Dude for overtime pay. Where did I get the circulation coupons?" Ji Sidui was not interested in the welfare of the indigenous people. "Don't they burn kilns in Fujian day and night? The kiln owner will give them overtime pay?"
"You capitalist is too evil,"
Ji Sidui interrupted his complaint: "I need this urgently, please hurry up."
After the cans are shipped back. Ji Sidui built a straw shed next to the sulfuric acid plant and slept for a while. At night, when the hour was up, he asked people to use iron tools to dig out all the firewood, and immediately organized people to put a layer of gravel that was about the same size as ore into the furnace, and then put firewood into the four furnaces to light the fire.
I saw the fire was getting bigger. Ji Sidui asked the workers to join the high-quality Hongji Smokeless Butterfly, and the fire suddenly became fierce, and the entire sulfuric acid plant burst into flames.
"Okay, except for the person who is watching the stove light up the fire, everyone else is going to rest. Come back to work the day after tomorrow morning!"
Seeing that he didn't have to worry about it now, Ji Sixui rushed to the next worker's caustic soda workshop.
The ammonia synthesis and combined alkali production plant can only produce soda ash. Caustic soda, which is widely used in industry, is relatively easy to prepare, and the raw material is simple salt electrolysis. Not only can caustic soda be obtained, but many useful by-products can also be produced, including another important chemical raw material: hydrochloric acid. There is no need to install a special hydrochloric acid production line, which is the benefit of the chemical combined manufacturing method.
Even the Ministry of Light Industry has been focusing on the issue of caustic soda, which is related to the two major products of the Ministry of Light Industry: white paper and soap. Ji Sixui simply did it together this time.
"I can drive one sheep or two sheep, so I can do more work." Ji Sixui thought about walking to the caustic soda workshop. A train carrying construction materials to the caustic soda plant happened to be passing by. He trotted a few steps quickly, climbed up, and sat down on a pile of reed mats.
"Who is it? You're trying to steal the train!" shouted a man wearing a safety helmet on the tractor in front.
"Are you considered a train?"
"It's not a train." As he spoke, the train arrived at the construction site of the caustic soda workshop, which was under construction.
Ji Sidui got off the car and saw that the man wearing a helmet turned out to be Bingfeng. It seemed that the caustic soda plant workshop must have a steel frame structure.
Sure enough, this caustic soda workshop is simple enough, but compared to the sulfuric acid workshop that is still exposed in the open air, it at least has the problem of covering the electrolysis workshop involving electricity. Cannot be exposed to wind and rain.
The entire building is a frame structure of brick columns and wooden beams. Except for a few key parts with walls, the rest of the building is open to facilitate ventilation. The precious and fragile transformers have separate transformer rooms with glass windows for easy observation.
The total area of the entire factory is approximately five hundred square meters. The floor is paved with bricks. Chang Kaishen is taking Ling Tian and several indigenous apprentices to install a transformer: convert the alternating current sent from the Bopu Power Station into direct current so that it can be used for electrolysis.
Ten electrolyzers have been installed. Ji Situi originally considered purchasing ready-made ones, but the weight made him give up the idea. In the end, only the core components were purchased and prepared in another time and space. The tank body is made locally. The square troughs are formed by braiding steel bars and casting them with cement yellow sand. Each trough is 1 meter wide, 1 meter wide and 1 meter high. The trough is lined with ceramic tiles to prevent corrosion. A barbed wire mesh is placed flatly in the tank at a distance of o, meters from the bottom of the tank. Each trough also comes with a wooden lid, which is coated with wood tar pitch to prevent corrosion.
The heavy reinforced concrete electrolyzer is supported by a piece of hardwood board and elevated on two brick bottom brackets as an insulation measure.
Ji Situi checked the quality of each trough to see if there were any spider joints or loose tiles. He found that the middle of the trough was paved with linoleum coated with asphalt as an additional insulation measure. Be careful and it will always fail. Wrong 4 port amps of current, this is no joke.
"Can this be safe?" Ji Sidui looked at this makeshift person. I really feel uneasy.
"It's generally safe, but I can't say absolutely." Ling Tian said. "You still have to rely on your own conscience when using electricity. Pay attention to wearing labor protection equipment and do a good job in safety education."
"The pressure is so heavy." Ji Situi has foreseen that the future of the chemical plant will not be peaceful, "The local law will kill people.
He turned around again and saw that a chlorine absorption tower combined with water tanks had been set up outside the house. The chlorine gas produced during electrolysis reacted through the slaked lime in the tower. You get bleaching powder. It is a cheap, effective and widely used disinfectant.
Returning from the caustic soda workshop. After another rest, the furnace work was finally almost over. At this time, everyone who had something to do with the chemical industry came.
"We won't sleep for two or three days in a row." Ji Sidui said and asked someone to drag out several boxes from the shed. "These are protective suits. Give them to everyone first, don't lose them! There is no place to find a mask or a pair of glasses now!"
Ji Sixui brought a lot of various labor protection supplies used in the chemical industry and there would be no place to replenish them for a while. He brought enough wearing parts to last him ten years.
Everyone wore full protective clothing. Wear protective glasses and other chemical masks. Then work started under the command of Ji Sixui.
Ji Sixui first closed the smoke-white blocking board. Then pull out the converter's draw plate. Turn on the blower. He kept measuring each one with a thermometer. Thermometer at the entrance. When the inlet temperature of the first converter reached the lock, Ji Situi asked someone to open the top cover of the converter and put in quartz sand and catalyst. Then close the top cover. Smeared with acid-proof mud and water glass is no longer a rarity in the soda ash industry, and porcelain powder is even less so, so Ji Situi had no intention of saving at all and sealed both top covers tightly without hesitation.
Seeing that he had sealed the top cover, Xu Yingjie and his men began to add crushed ore into the furnace. Each furnace has a capacity of kilograms. Then close the oven door. At the same time, concentrated sulfuric acid obtained from the Planning Commission warehouse is added to the absorption tower as a primer to start the acid cycle.
Ji Sidui tested the concentration of sulfur dioxide at the outlet of the first converter, and it was already close to the edge. He knew that the preparation of sulfuric acid had been basically successful. After the absorption tower starts the acid cycle, liters of acid are sprayed every ten seconds. Tawen had already risen to the altitude, and he asked people to turn on the water cooling.
In this way, one furnace is charged with ore every hour, and the four furnaces are cyclically charged and slag is discharged. This is how the indigenous sulfuric acid plant is operating. Just maintain a steady flow of ingredients and fire. A workshop of this size can run Bitian every year. Concentrated sulfuric acid for production
Ji Situi and others had no time to celebrate this great moment. Instead, they were busy explaining the key points of production to the indigenous workers while working. On-site observation was more intuitive than simply giving lectures in class and adapted to the cultural level of the indigenous workers.
Of course, once it is running, the furnace will not be shut down unless it is for maintenance or other important matters. After all, heating the furnace takes a long time and consumes a lot of fuel, which is not economical.
However, Ji Sidei only had pyrite stew in his hands, and he would not be able to operate even one of them at full production. The month is gone. When the pyrite will be shipped again depends on how fast shipbuilding can be done, but by this time the sulfuric acid for coal coking should have been mass-produced. Sulfuric acid production here would not be too important. Ji Situi is already considering that if the coal chemical plant has enough sulfuric acid, the equipment here can be used to produce sulfuric acid from pyrite as fertilizer.
The first batch of 10% concentrated sulfuric acid was produced. They are carefully packed into custom-made jars and sealed. The outside of the lid is then closed with plaster of paris plaster. It was covered with a clay raspberry to protect it from rain.
"Does this method work?" Xu Yingjie is used to seeing modern industrial packaging. Now at first glance, when he saw a clay pot that looked like rice wine, he felt incredible and had a very unreliable feeling.
"Sulfuric acid has been produced for two hundred years. Don't worry, it was always packaged like this in the past." Ji Situi said.
After the can is labeled with "Concentrated Sulfuric Acid", the date of production, and the place of production. It was carefully packed into a wooden box specially made by the carpentry factory. One or two per box. Straw ropes were wrapped around the cans in the box to act as shock absorbers. Then he was loaded onto the train. Transported to chemical dangerous goods warehouse
.
After the initial victory in the sulfuric acid battle, Ji Situi led the indigenous workers to teach while producing for more than ten days, until the indigenous workers basically mastered the production technology and processes, and memorized all safety production regulations. ! ~!
