Thank you for the 2000 prize 160227185121508 your good book friend and the reward from your friend Gate Valve Gravedigger At present, Yang Yan has no shortage of technology, no shortage of raw materials, many common chemical reactions can be completed under simple natural conditions, without too precise instruments and equipment and exquisite environment, what he lacks is people.
There are only more than 20,000 people under his hands, including a large number of old and weak women and children, Ding Zhuang is not even less than 10,000, half of them are soldiers, in addition to shipbuilding, he has already opened a saltpeter industry, salt industry, paper industry, coal and iron industry, and there are people to plow the fields, manpower is really stretched, but even so, he is still careful in his calculations, and he has transferred 500 people to mine lime mines.
This is really a blessing in troubled times, as long as ordinary people have something to eat, they will not make trouble, if they are left in the era of the Song, Ming and Qing dynasties in the future, such as his abuse of people's power, he would have complained a long time ago.
However, in addition to the fact that craftsmen often need to work overtime, Yang Yan strictly implements the four-hour work system, and does not squeeze the surplus value too much, so his beer is still very good.
Of course, this oldest group of patriarchs Yang Yan will also remember that he will select talents one by one in the future, and ascend to a high position as he grows.
The limestone is located in the hilly and mountainous area of about fifty miles north of Tancheng, in the territory of Wangzhuang Village, Miaowang Town, Tancheng County today, the mining area is more than 100 acres.
Even Xiao Qiaoniang asked privately: "Lang Jun, can you find a gold mine?"
Yang Yan smiled: "You little money fan, how can gold be so easy to find." ” In fact, Yang Yan was insincere, the gold was really there, on the Jiaodong Peninsula, Cao Wei's territory, he remembered clearly, during the entire Liberation War, the People's Liberation Army mined a total of 420,000 taels of gold on the Jiaodong Peninsula, effectively supporting the Liberation War, but at present, his hand cannot reach Jiaodong.
Qingzhou Yang Yan couldn't help but look to the north.
For him, the gold in Jiaodong is not in a hurry, but the graphite mine has always been worried that with graphite, it is possible to build crucibles, fire molten steel, and directly cast steel components, especially steel nails, because iron nails are easy to corrode in water, and replacing iron nails with steel nails can make the ship stronger and extend the maintenance cycle.
At present, limestone can only be mined honestly, limestone can not be mined and used, but also needs to be calcined at a high temperature of 1000 to 1100 degrees Celsius, and carbon dioxide can be discharged to obtain relatively pure calcium oxide, that is, quicklime.
Ten days later, the first batch of about 50 stone quicklime was baked, transported by mules and horses to the edge of Yishui, where a large pit was dug on the spot, covered with quicklime, and placed freshly cut wood on top, and another ditch led into the pit.
Jiang Zhao and the boatmen are holding their breath, if this method can be achieved, the efficiency of shipbuilding will be increased several times, as a person who has dealt with ships all his life, how can he not be eager for it "Drain the water" Yang Yan gave an order.
The boatmen dug a ditch to divert the water in, and saw a waterline poured into the pit, and in an instant, the water boiled, and the smoke covered the sun, even from a distance, you could feel the heat wave coming to your face "General, this law will be done" Jiang Zhao's family heirloom shipbuilding, just experiencing the heat, he has a little certainty, and he can't help but exclaim excitedly.
"I hope so" Yang Yan smiled slightly.
The water gurgles and burns, the quicklime reacts with the water, and the temperature released exceeds 100 degrees, plus the hydrated lime has a destructive effect on the cell membranes of animals and plants, and the two phases are superimposed, which is enough to kill the undead cells in the trunk.
Everyone pointed and pointed, and the excitement was overflowing, and they were both puzzled by Yang Yan's ability to exceed the times, and gradually became accustomed to it, and Xun Hua's heart was more proud.
In Yang Yan's eyes, this is a complete alkali chemical industry chain.
Quicklime was placed in that era, it was the most perfect desiccant, and in the warehouse where the grain was stored, sprinkled with quicklime could effectively absorb water and prevent the grain from becoming damp and mildew, and it was also particularly suitable for the production of shiitake mushrooms and fungus.
Yes, with enough manpower in the future, Yang Yan will promote the cultivation of shiitake mushrooms and fungus, as well as various medicinal and edible mushrooms.
And add water to quicklime, can not only cook wood, but also can get slaked lime, slaked lime is more widely used, in addition to building raw materials and sterilization and disinfection, can also be used for the bleaching of pulp and deacidification of sugar, sucrose at that time, because the process is not up to standard, generally with a sour taste, such as after slaked lime treatment, can be made similar to modern common white sugar.
It's just that Huaibei does not produce sugarcane, and the purified caramel has to be put in Jiankang, but another key use of hydrated lime is to mix it with copper sulfate solution in a certain proportion to make pesticides.
The preparation of copper sulfate is more troublesome, the natural copper sulfate is called bile vanadium, which is about produced in Yunnan and Shanxi, Yang Yan wants to fight the past, and he does not know the year of the monkey, but it doesn't matter, the copper can be burned into copper oxide, and then made with sulfuric acid.
So where does copper and sulfuric acid come from?
Copper is produced in Tongling, Anhui, that is, in the Xuancheng area at that time, sulfuric acid can be produced from pyrite, and pyrite is produced in Ma'anshan, Anhui, that is, Gu at that time, these two places are still qualified to occupy in the future.
After all, in order to increase agricultural production, in addition to advanced farming methods, chemical fertilizers and pesticides are also indispensable.
Soda ash is mainly used in the manufacture of flat glass and glassware, as well as leavening agent for pasta, and alkali agent in animal fur washing and tanning.
In fact, in Donghai County, now Lianyungang is attached, there are huge reserves of quartz ore, Yang Yan also knows that the glass is good, but he really has no one at hand, so he can only leave it for later.
Relatively speaking, caustic soda in that era, some chemical and textile applications have not yet been conditioned, the direction of application, just soap and papermaking, caustic soda paper, can effectively separate the non-cellulose components in the pulp, make the paper more tough and delicate, and then bleached with hydrated lime, Yang Yan is confident that the future of Yang Lang paper, enough to sweep Jiankang The ancients were not stupid, such as the lime industry chain and other projects that focus on operations, you don't need to know the principle, as long as you tell him the steps, 12345 is clear, and the same can be done, in the end, there is still a shortage of manpower Yang Yan sighed secretly, if he could master the entire territory of the East China Sea, it would be enough to create a modern alkali industrial chemical chain Now Yang Yan no longer has extra manpower at hand, everyone has something to do, and the whole army is like a taut clockwork, working in an orderly manner, gradually accumulating qualitative energy through quantitative changes.
Another three days passed, and the first snow since the beginning of winter fell in Tancheng, and the north wind was howling between heaven and earth, and it was vast.
Modern people look at the snow, that is the beautiful scenery, and in ancient times, a heavy snow was enough to freeze many poor people to death, but with the promotion of honeycomb coal, every household is as warm as spring, and spend the winter in peace.
It is not only more than 20,000 people here in Yang Yan, the coal stove and honeycomb coal have also been introduced into the dock fort of the big households in Tancheng, the coal furnace has no technical content, and the skilled craftsman can make it at a glance, but the honeycomb coal is different, if you don't add yellow mud, the coal will be burned out quickly, add more, the fire is not prosperous, and the formula is strictly confidential, so although Tancheng Chenghao imitated the honeycomb coal, the effect is not good, either it is not warm enough, or it will burn out after a while, and the coal has to be changed at night, disturbing the sleep of the main family.
In desperation, I could only buy it from the Prime Minister's Office.
The price given by Yang Yan is quite fair, two liters of wheat for one honeycomb coal, or three liters of beans, small households need to use hundreds of them every day, and large households need to use thousands.
However, this price is really not expensive, Yang Yan once sold charcoal, five yuan per catty, converted into one liter of grain, and the weight of a coal is more than one catty, and the combustion efficiency is not worse than the same weight of charcoal.
At that time, wheat was cheaper than rice, so two liters of wheat was one coal.
Salt is also sold at market price, the price of salt is generally seven to eight times the price of rice, that is, about 10,000 yuan per stone, in this place of Tancheng, Yang Yan does not collect money, all to grain and cloth converted, of course, to gold and silver he is more welcome, oil is the same price as Jiankang, in fact, even if you do not farm, the income from coal, salt and oil alone is enough to feed more than 20,000 people in the whole army.
On the morning of this day, Yang Yan took Xun Hua and Xiao Qiaoniang to see what the teaching effect of Cui Wan and other scholars was on the children, and what words they could write after learning those articles
