Taking advantage of the opportunity of several new governors, Marin thought about it and planned to summon these four new governors and set up a governor training class to teach them some precautions. Of course, the most important thing is for them to understand the specific responsibilities of sending them to be governors.
For example, Albert went to the two islands of North America in order to expand inland, and the means were gentler. Tara went to Havana, mainly to cultivate land, and at the same time, to conquer those Taino.
Gorard ’s task is relatively simple. He is a contractor, going to Panama to cut trees, grow grass (pyrochlore and wormwood), and build roads. In order to open up the passage to the Pacific Ocean. Of course, he is the most dangerous. If he suffers from yellow fever, he will not be saved.
As for Wiltz, his mission is also quite special, he went to Cuba to mine. Fortunately, the laterite nickel mine is red and very good for exploration. If it is a mine of another color, it may not be so easy to find. Moreover, Marin remembers that there was a large red mine in the middle of the two lakes east of Moa in the previous life. Therefore, it is very easy for Wiltz to find laterite nickel ore. It is another kind of stainless steel mine-chromium, which is a bit troublesome to find. Marin knew that there was a chromite mine with millions of tons near Moa, but he didn't know where. Fortunately, Wiltz was a prospecting engineer. When the time came, he asked him to look for chanting near Moa. He would look for iron ore, find all the iron ore nearby, and then slowly judge which is chromite ...
Anyway, the iron ore found was directly reduced with a simple blast furnace. What is reduced by chromite is ferrochromium alloy, also called chromium steel, which is not easy to rust. Those that are prone to rust are definitely not ferrochrome. Then, the nickel extracted from the laterite nickel ore is mixed with ferrochromium and refined to obtain stainless steel. Although the chromium-nickel content is not well controlled, it is stainless steel. What I need is to replace the copper skin around the lower part of the ship's waterline, but it is not used to make precision instruments. Therefore, the requirements for stainless steel are not so high, as long as the corrosion resistance is not worse than copper skin.
Although the four people can be trained separately, there is no need to take classes together. However, Marin believes that as a governor, he should have rich experience and a good overall view. Therefore, when explaining to one of the governors, the other three people may listen as well. Maybe, in the future, they will need to use some of this knowledge? After all, their current governorship is not a lifelong system. Maybe they work in this environment today. Maybe they change the environment tomorrow. Just like Tara, I used to work in Shuangdao, but now I went to Havana again ...
...
Looking at the four people who sat down and listened like primary school students, Marin was very satisfied. If anyone is not serious about learning knowledge, Marin will have to consider whether it is time to change people.
First of all, Marin wrote the phrase "Drinking raw water" on the blackboard, and then let all four remember it firmly, and implement it resolutely.
"But, Brother Marin, why would you prohibit drinking raw water?" Albert asked puzzled.
"Albert, from the moment you sit here, you are a reserve governor, no longer a child. So, you must obey the rules, and at work, you should call me Lord Duke, not brother ! Only in private, you can call me brother! Do you understand? "Marin reprimanded severely.
"Oh ..." Albert responded grievously.
"Albert, you are about to become the governor of the management side now. So, the first common sense I teach you today is to be public and private. This governor training course is obviously a business occasion, not a private one, so, I asked you to change your title. Do you understand? As a governor, the first thing to do is to distinguish between public and private! Tell me, do you understand? "
"Understood!" Albert stood up and replied firmly and loudly.
"Very well, it should be in this state."
"So, next, let me explain to you why you can't drink raw water ..."
Then, Marin and everyone explained in detail what microorganisms are, and when some harmful microorganisms enter the human body, it will cause people to become sick and so on ... Unfortunately, after the lecture, the four people are all in a dumbfounded manner ...
Obviously, they have no intuitive understanding of microorganisms. Unfortunately, Marin now does not have a microscope in his hand and cannot show them the presence of microorganisms.
Finally, Marin was on fire and said loudly:
"Anyway, you only need to know that drinking raw water will make you sick. Especially in tropical areas, it is easy to get plague!"
"The plague?" All four were startled. Although they don't understand what a microorganism is, they still understand what a plague is. As a result, the frightened four nodded one after another.
"Also, once a plague or infectious disease occurs, it proves that the water source there may be a problem. At this time, the best way is to drill wells and drink well water. Of course, you have to boil and drink."
"Then Duke, is it okay to drink cool white?" Wiltz asked weakly.
"The cool boiled water is also boiled boiling water, no problem. However, the cooling time should not be too long. Otherwise, the microorganisms will still invade. That is to say, the boiling water cools down for a short time, and it must be no problem to drink. The time is long, sure No. "
The four nodded one after the other, so the first principle of the colony finally left a deep impression in the hearts of the four.
Then, Marin began to coach Albert, the highest of the four, and the other three listened:
"North America ... Abu, the Indians of the northern barren continent are divided into multiple branches, some are more moderate, such as the Drava, and the Wampanoag who Tara just contacted. However, Some Indians are more combative. Because they often hunt in the dense jungles of the northern barren continent, they have developed a fighting ability to fight nature. "
"Of course, fighting against them is not terrible. The most terrifying thing is that the Indians are hiding in the dense jungle and letting cold arrows attack you. Therefore, I let you draw the Delaware. Familiar with the forest, not afraid of other Indians' bow and arrow raids. "
"At that time, you hire archery proficient in the Delaware and Wampanoag people, and replace them with excellent bows and arrows made in Europe, which will definitely suppress the indigenous bow ..."
Albert nodded again and again with a look of admiration. Use the Indian jungle old driver to deal with the hostile jungle old driver, and also use special weapons to suppress it. There is definitely a chance of winning.
"In addition, you have to hire friendly Indian tribes, desperately cut trees, and cut down the trees. Those Native Indians who are good at jungle warfare will not be worth mentioning. As long as a simple charge of the cavalry, you will win."
"So how many troops are sent to me?"
"You just went now, don't think about fighting, first find a way to establish a relationship with the Delaware, and buy Manhattan Island as a foothold. At the same time, buy oak logs. Fighting, it is estimated to wait. In addition, I will also select strong plate armoured infantry for you. Besides, you are the governor, and fighting has nothing to do with you. "
"Ok……"
...
Next, Marin instructed Wiltz:
"This place you are going to has a very valuable mineral deposit called nickel ... uh, I don't know what nickel is? No problem, let me tell you ..."
Barbara talked about nickel for a long time, and Marlin stopped after he was about to faint.
"In short, in the southeast of Moa, between these two lakes, there is a red clay area ..." said Marin, drawing out the approximate locations of the two lakes.
"After finding the red clay area, dig out the red clay, set up the furnace at high temperature and calcinate with air ... At this time, irritating gas will escape. By then, your entire desulfurization tower will be desulfurized with water ..."
"Adult, what is the whole desulfurization tower?" Wiltz was a little stunned ...
"Mad, it's not a thing, you just need to know how to use it ... specifically, the exhaust gas of the calciner is passed through a pipe into the pool to avoid the escape ... because, this gas, it dissolves Water ... collected to make sulfuric acid ... "
"What is sulfuric acid?" Wiltz was curious.
"Your uncle, sulfuric acid is not, you don't need to know what it is, you just collect it, you don't need to know it! Remember, the water should be changed frequently, otherwise the sulfur dioxide dissolved in water will be saturated ..."
"Oh ..." Wiltz nodded obediently, without refuting.
As for how the generated sulfurous acid becomes sulfuric acid, Marin decided to let it go, how much can be converted, anyway, constantly stirring the sulfurous acid, mixed with air (oxygen), can always convert a part. Over time, it can slowly transform a lot.
As for how much can be converted in the end, it is purely God's will. Anyway, Malin's demand for sulfuric acid is not large. In fact, Marin knows how to convert so2 to so3 in industry, but it requires vanadium pentoxide or platinum as a catalyst. But both of them are not the same as Marin, so they have to choose natural transformation. Although the efficiency is low, it is also a helpless choice. Moreover, because the chemical industry has not developed, the demand for sulfuric acid is not large.
...
Seeing Wiltz seem to understand, Marin did not expect him to understand immediately. So he simply let the craftsmen build a complete set of calcination and water desulfurization tower equipment, which can be used directly by Wiltz.
After calcination, nickel sulfide is converted into nickel oxide, which can be reduced to nickel by going to the blast furnace ...
Then, Marin told Wiltz to let him carefully search for iron ore near Moa. If you find an iron ore, use a blast furnace to smelt it out and have a look. If it does not rust, it is ferrochrome. Then it is melted and mixed with pure nickel, which becomes the legendary stainless steel ... It is said that there is a chromite mine called Mercedita near Moa, with a reserve of up to 1 million tons, of which chromium oxide (dioxide) Chromium) content is as high as 38.40%. As long as you find this chromite ... well, it is estimated that you have to add some iron into it, otherwise, the smelted metal contains too high chromium ...
Marin remembers that 304 stainless steel, which is commonly used to make stainless steel lunch boxes in later generations, contains 18% chromium and 8% nickel. Because of the limited technological level, Marin certainly cannot accurately produce 304 stainless steel, but it can still be done with more chromium content, which is not a bad thing anyway. As for nickel, because it is separate from ferrochromium, it is easy to control the content. Anyway, the higher the chromium content, the stronger the corrosion resistance. What Marin wanted was corrosion resistance, and when it was done, it would be possible to get the iron sheet that wrapped the hull. Moreover, at the current industrial level of this era ~ www.novelhall.com ~ that 1 million tons of chromite, it is estimated that Marin can't run out ...
After tutoring Wiltz, Marin tutored Tara and Gorad. For Tara, Marin is still very at ease. Especially in the pioneering area, Tara is already very experienced. After all, Tara has already experienced the pioneering of the two islands. But Marin told him that he had to establish a good relationship with the local Taino patriarchs in the early stage. If the Taino patriarchs believe that Havana is their site, then they can send them some glass ornaments to "buy" the land to avoid disputes.
Then, among the nearby tribes, find and support those close to the colonists, support them as leaders, and finally bring those tribes under their rule. Next, train a group of Indian warriors, specialized in disguising as the Tynoes ’Caribbean enemy, the Caribbean, and kill the chiefs of the remaining tribes. "Caribbeans" pretend to play a game, so that they return to their hearts ...
Listening to Marin ’s conspiracy against the Indians, the four new governors are all sweating and sweating-special meow, I ’m just going to be governor, not conspiracy and conspiracy ... but these methods sound great. Oh……
As for Gorad, Marin said nothing, just let him build a base in Cologne. Then, plant wormwood and pyrethrum around the base, and then, rely on the black slaves bought from the Portuguese to let them cut trees and cut in the direction of the Pacific until a road is cut. In the future, we will transport some cement and lay a cement road that leads directly to the Pacific Ocean to facilitate transportation ... In short, Gorard ’s responsibility is to be a contractor who builds roads and cuts trees ... Of course, you must always pay attention to safety. To avoid terminal illnesses such as yellow fever ...
