In nature, phosphorus is mainly stored in the form of phosphates, such as calcium phosphate.

In that world, calcium phosphate ore is used industrially to produce white phosphorus, which is to mix calcium phosphate, sand (silica) and coke, and stir-fry in a high-temperature reaction furnace, so this reaction will occur:

2ca3(po4)2+1oc+6 private O2=6Caprivate O3+p4+1onetbsp; Under sealed conditions, white phosphorus is obtained by condensing the obtained phosphorus vapor.

Hantang Group has a high-temperature reactor, which is a set of equipment to be shared with the future production of calcium carbide.

However, next, the Hantang Group will not have that good fate. Taiwan is an island lacking phosphate mines, and there are no ready-made phosphate mines waiting for them to mine.

The total amount of phosphate rock in Mingda 6 ranks second in the world, but it is mainly in Hubei, Hunan, Sichuan, Guizhou, Yunnan and other 6 provinces, and the closest to the sea is still in the Jinping area of Jiangsu - Hantang Group is really beyond the reach of the whip.

So they hit strouncers and bones.

Struvite is a natural phosphate fertilizer, which goes without saying.

Bone is composed of 3o% organic matter and 7o% inorganic matter, and calcium phosphate accounts for 95% of 7o% inorganic matter. This is why the ancients knew very early on that bone meal could fertilize fields.

In some coastal areas of Mingda 6, small trash fish were caught in some places, and they could not be eaten for a while, so they were all soaked in the ground. This can achieve a certain increase in production.

The Hantang Group's fish catch is mainly in the estuary base, where there is the world's largest comprehensive fish processing plant in this time and space, and a little further away, there is a fish bone accumulation field, which is really a sea of fish bones.

The people of the Hantang Group were too lazy to use the precious equipment to dry them, so they let them be exposed to the sun - after a day or two of drying, the Ming laborers went to transport back a batch, simply crushed them with stone rollers, and let them take them away when the Budai Salt Chemical Industry Zone came to deliver various raw materials.

It's best to take them all away, the whole estuary base, this place is the most attractive for flies - fortunately far away, otherwise the smell is not something that ordinary people can bear.

This status quo is not in line with the concept of a garden-like industrial zone pursued by Director Song Shida, but there is no way, and the reality of life is often greater than the pursuit of life - that place will be preserved for a long time.

Now, the Budai Salt Chemical Industry Zone is about to become a second fish processing base.

Many of the Ming fishermen had finished their fishing and had paid their fishing taxes in the city of Geranza, and then they received new little flags and hung them on the sails of their ships. In this way, the sailing ships that often patrol the coast and coast will not let them stop to check taxes when they see them.

It would be even better if they could sell all the fish left after paying the tax at the market in the city of Geranza on the same day, because the fishermen would not have time to squat in the market to sell their goods.

If there is still a few fish left, they sail directly to Budai Town, where the price of salt is now very cheap, and they can buy salt directly to deal with it, instead of carrying it themselves, and save space. Anyway, it's all along the way, and Budai Town is the closest place to Xiamen. After processing, it will be transported to Xiamen to sell, which is very convenient.

Director Sun De took advantage of the situation to designate a flat place on the shore for them to concentrate on processing the catch, and at the designated place to fatten the internal organs of the fish and dry the bones of the fish. They are not allowed to throw away at will.

It is far from the industrial area and the three salt works on the shore, so it does not cause pollution. Later, some fishermen suspected that the boat ran up and down when handling the fish, and it was troublesome, so they built a bamboo shed here.

After coming and going, it has also become a fishermen's concentration area, and there are Ming farmers in Budai Town who take the initiative to buy catches, which of course the fishermen are happy, otherwise they need to bring back Mingda 6 to sell, wouldn't it be better to solve it nearby? Of course, there are also some small traders who come to sell some daily necessities.

Director Sun De knew about the changes here, but he didn't even want to manage it - let them go to the exhibition on their own, many of the problems of the exhibition are often brought by the managers themselves. Give them a space to grow freely first.

As struvite and fish bone meal collection progressed, the Hantang Group began trial production of white phosphorus. After careful preparation and careful production, the trial production has achieved certain results - if calculated at the cost of that world, they will have to lose money, but they are in this time and space - everyone is satisfied with the results of production. But if they want to solve the problem of phosphate fertilizer in one fell swoop, they still have a long way to go. But at least there is hope.

With white phosphorus, there is also red phosphorus, and the conversion process is very simple. An isolated air heating can be used to convert them into each other.

With white phosphorus and red phosphorus, there is phosphoric acid, and the production process is even simpler, after ignition, it is phosphorus pentoxide, which reacts with hot water to form orthophosphoric acid. It must be hot water, and if it is cold, it will become a highly toxic metaphosphoric acid.

At this point, the chemical companies of the Hantang Group can say loudly that they can produce the main acids and alkalis that the world has - of course, far from being able to produce them, but at least they are invincible in this time and space.

In the days when the Mid-Autumn Festival is approaching, the Budai Salt Chemical Industry Zone is full of festive festivities, and every technician is smiling.

Happiness is contagious, many Ming workers can feel the happiness of the Hantang Group, although they don't know that the people of the Hantang Group are not only happy for the Mid-Autumn Festival, but their hearts are also happy, yes, the Mid-Autumn Festival is coming.

However, this happiness does not belong to the people of the Salt Works.

Shi Tou finally built his own salt farm, and every time he inspected his own salt farm, he had to spit hatefully at the Pan family salt farm in the distance - what the hell, people were just about to build a salt farm, and their Pan family also came to grab food - aren't you the Pan family in Guangzhou?

Shi Tou led a group of brothers, poured the bitter salt stone early or late, and finally one day changed enough cement needed - he happily said to Yang Jianguo technician: "I can't transport the bitter stone for the time being, and I want to build my own salt factory, Anchang Factory personally said to the small one, the bitterone is enough for the moment - if it is used in the villain's place in the future, but it doesn't hurt." ”

Technician Yang Jianguo said lazily: "Hmph, if you want to start your own business - where is it so easy?" ”

Shi Tou said goodbye with a smile on his face, turned around and walked a few steps.

Yang Jianguo technician said lazily again: "Just after eating, you have the idea of flying solo?" I heard that Pan Jiake is also going to build a salt factory. ”

Shi Tou laughed again and again, and was busy saying, it's okay, it's okay, everyone does their own thing.

However, it turned out later that the Pan family's participation was very harmful.

The first is the degree of construction of salt pans.

When Shi Tou and his brothers had just finished half of the construction, their Pan family began to build, but when they finished building, the Pan family was also completed, and although their scale was not as large as the Budai Salt Factory, it was more than two larger than Shi Tou's salt factory—there were many of them, and I heard that it was cement bought at a high price. How can Hantang Group sell their cement casually?!

Then there is the windmill equipment for lifting water in Yantian.

The water-lifting windmill designed by the Hantang Group is very different, facing the sea during the day and turning it back to the sea at night, as if to use the convection caused by heat exchange or something - but it works very well.

Shi Tou calculated that this water-lifting windmill would save at least ten people - but the price was not expensive, at least the bearing or something, he had carefully studied it in Shitou, and ordinary blacksmiths probably couldn't build it - I heard that it was made by the great craftsmen of the Red Star Industrial Zone.

Of course, Shi Tou didn't know that it was just a handmade product from the Mingren hand forging workshop of the Red Star Forging Factory.

Shi Shouyi ruthlessly took out a loan to buy three units, but this was because the kind-hearted director of Andefu said that when the time came, he could use salt to take out a loan without interest.

The Yang Jianguo technician said to him in a weird way: "You want to make a big show, don't forget that the Pan family directly bought nine units." ”

Shi Tou smiled bitterly at the time, casually made a gesture to Yang Jianguo's technician, and left.

At that time, the arrow was already on the bow, and he knew that the Pan family was really doing this business, so he didn't do it, but now he has done half of it, and if he doesn't do it, he can't explain it to his brothers.

Besides, after they resigned from the promising job of the salt factory, the Budai Salt Factory recruited many salt workers, and there was no way out to go back, unless they expanded the area again, just like their so-called second phase of the project, but looking at the current table of the Hantang Group, they had no intention of doing so, and they didn't know what they were busy with.

Both salt works were completed at the same time. What makes Shi Tou happy is that at least they themselves also put a big hanging hemp thunder cannon, which added a lot of joy out of thin air, and what about their Pan family? Lonely and lonely led seawater into the field—

The Pan family, like them, also built a bamboo shed by the salt pond, and hundreds of salt workers rested there - phew, why don't you blow your windmill and blow your bamboo shed away, always learn from me to do things, or a big family, bullshit!

Of course, these are just Shi Tou's private complaints, and they can't be put on the table, on the day of the sea introduction, an elder from the Yantian of the Pan family came to visit with a congratulatory gift.

The faces of his brothers were not good-looking, but Shi Tou was full of spring breeze - he answered reasonably, and asked his brothers to hurry to return the salute.

Shi Tou said to his brothers: "You are all blind, his jade pendant is worth the salt field we are waiting for, come to visit in person, we are big enough, this person is by no means a good person——"

But things are not so bad - the Panjia salt farm seems to be interested in selling salt locally, and after the first batch of salt was collected, in addition to paying the tax with salt and handing over a part of the Hantang Group, they actually came directly to the ship to send it away-

This made Shi Tou feel hope, and he immediately asked his brothers to carry the salt, and transported the salt in a wheelbarrow, to the market in Gelansha City, to the Chiji Agricultural Base, to the second layer of Xingxi to sell, and even prepared to go to the northern region of Taiwan to sell, I heard that there are more and more foreigners there-

Haha, the people of the Hantang Group don't know that salt is absolutely not allowed to be sold privately in Mingda 6, and while they don't know, sell more - this price, they don't have the official salt, so there is no reference, but as long as it is cheaper than the Hantang Group, it is easy to sell, every time Shi Tou sees the amount of salt collected in their bag salt field, it really makes people feel a sense of powerlessness, they are piling up mountains.

But they're more used in the factories in Budai - it's a once-in-a-lifetime opportunity!

In the small market that has formed itself on the coast of Budai, fishermen can often see people from the Shitou Salt Works pushing several wheelbarrows of salt, and the fishing boats are delivering it to the bamboo huts one by one.

The fishermen knew that the price of salt in their three salt farms was about the same, and Shitou Salt Farm personally delivered it to their doors, but they saved themselves from buying the salt themselves, so they also bought the salt one after another.

Shi Tou fanned the wind with a hat, and watched with a smile as his brothers collected horse tickets or silver taels - he swore in his heart: After we accumulate more, we must build another salt farm bigger than the Pan family!
