After a while, the laborers collected a few kilograms of white crystals for Zhang Guoan. Pen ~ fun ~ pavilion www.biquge.info

Zhang Guoan stopped them, and these were enough.

He had just observed that the process of finding phosphate was too time-consuming, and it was not as simple as burning the ashes directly, although the smell was unpleasant, but the rest did not cost anything.

Zhang Guoan carried a basket of phosphate and went to the coppersmith again.

The quality of the bronze cannons and bronze tiger squat cannons they cast last time was very good, which shows that they still have very practical experience in grasping the material of bronze products------

He said to the coppersmith, "What is the proportion of tin in copper?" ”

The coppersmith said, "If you cast small things, you should generally have less; If it is a large casting, it is generally necessary to have more ------ medium things, and it is generally necessary to add one percent. ”

Zhang Guoan is glad that he can still hear an accurate number.

He said: "In this way, you weigh 100 grams of tin and 8 grams of struvite, and finally weigh 1,892 grams of copper, and then melt it into copper, and let the director of Hu Zhenbei take part of it and make it into a V-shaped spring------ and then find me!" ”

Previously, Zhang Guoan had popularized weights and measures in the Badaohe area and distributed measurement tools, but now he has saved himself a lot of things.

Zhang Guoan then began to prepare for the extraction of white phosphorus.

He is now very annoyed by the Great Song Dynasty's way of making fire, he is not even as skilled as these ancients in making fire!

The plane uses a fire made by striking a fire with a fire that resembles an iron clamp with iron at one end and black or white flint at the other, and then strikes it in half to make the sparks burst onto the hay.

This action requires strength. But it is not necessary to have a lot of strength, it needs to be beaten for a long time to slowly master the skills, one is the strength is just right, and the other is the angle must be controlled, just so that more sparks burst onto the hay, and it is necessary to blow in time------ Zhang Guoan is not good. Silence doesn't work.

Every time Zhang Guoan smoked with Hu Zhenbei blacksmith, Hu Zhenbei blacksmith lit the fire, and every time at this time, this guy revealed, "You can't even make a fire?" More importantly------ he still wants to expand his product range, and the matches that are on fire will definitely be sold at a good price.

Of course, he would not be stupid enough to process white phosphorus matches directly, that would cost his own life.

White phosphorus has a lethal dose of 0.1 grams!

He was ready to mount trisulfide tetraphosphorus matches.

Tetraphosphorus trisulfide can be obtained by direct combination of white phosphorus and sulfur, and it is not very toxic. I haven't heard of this thing poisoning anyone.

It is not afraid of moisture, as long as you scratch the surface of a waterless object, it will be the same.

Of course, this thing rubs against each other repeatedly during transportation and is prone to spontaneous combustion, but there is a way to solve it.

For example, put them at certain intervals on the packaging, even if they are all vertical packaging, each with its own socket------

These questions are simple. But first there is white phosphorus.

Zhang Guoan used the soil method to get white phosphorus.

He first had the ashes of the fish burned, especially the whale's large ribs and vertebrae. It is also easy to collect ashes.

The white phosphorus reactor was cast by a coppersmith earlier, it has a diameter of 50 centimeters, a height of one meter, and a pipe-shaped lid. It's still the old way, and in the end it has to be sealed with clay and sealed repeatedly!

There was a five-centimeter-diameter hole in the lid of the pipe, which was reserved for the clay tube to be used as a condenser tube, and the other side of the clay tube was bent down. Sticking into the water in the porcelain jar.

After condensation, the white phosphorus vapor basically does not dissolve in water, but directly precipitates.

Zhang Guoan asked the whale ashes to be crushed finely, and then mixed with three times the river sand of the whale ashes and five times the charcoal powder, poured into the white phosphorus reactor, and directly heated with the alcohol stove designed by Zhang Guoan!

The overall reaction equation for this process is: Ca3(PO4)2+3SiO+5C=3Casio3+2P2+5Co.

During the first processing, Zhang Guoan led a few laborers and stood two or three meters away.

He pointed to the porcelain jar and said to a few people around him, "Wait until there is a gurgling sound in there, it is carbon monoxide coming out, and you should stay away; When there is no more sound, you can come back here and see if there are any cracks in the clay cover. If you have one, add clay! ”

After a while, sure enough, there was the gurgling of water, and they retreated together.

In the end, Zhang Guoan got less than 100 grams of white phosphorus from a large pot of raw materials------ but fortunately, the raw materials did not cost him, and he asked the laborers to continue to work.

After waiting for the white phosphorus reactor to cool down, he squatted on the side of the porcelain jar, pointed to the white phosphorus sediment of about 100 grams, and said, "When there are ten times more than that, you can change the jar and send this jar to my office with water." ”

A few laborers agreed.

Zhang Guoan had to go back to the office, because the prince of Zhongshan Kingdom in the Ryukyus came again, and he also brought more than 200 buffaloes, all of which were buffaloes that could directly plow the fields, and more than 1,000 migrant workers.

After Zhang Guoan heard the number of buffaloes he said, he was very happy and asked directly: "How is your great cause of reunification?" ”

"Bow Zhang, very good! After World War I went down to Nanshan Province, and after World War II, Beishan Province went down to Japan, and our Ryukyu Kingdom was revived! ”

Zhang Guoan smiled in his heart, how many places and populations are there in the three countries combined?

The crown prince of the Ryukyus Kingdom said: "This time, I also want to buy some potatoes and sweet potato seeds, which I will distribute to the people who have returned from the reconquest-----. ”

Zhang Guoan nodded in approval, this kid has vision.

The prince of the Ryukyus Kingdom said: "I also want to exchange for a batch of arquebuses, palm mines, and some more ammunition------ I myself stay here, and learn the techniques from Zhang Chuanshou, a hundred scriptures, not as good as an arquebus------ and in addition, Zhang Chuanshou presented four handmaidens, they can understand the Great Song dialect." ”

Zhang Guoan can't refuse, and he doesn't want to refuse, he must be quietly accepted anyway------

However, he asked curiously: "The great cause of reunification has been accomplished, so why bother to increase armaments?" ”

The prince of the Ryukyu Kingdom said: "The Great Song Dynasty regards me as a child, and the Wa Kingdom regards me as a meat belly!" ”

Zhang Guoan nodded in approval, in a few hundred years, you will definitely be cleaned up by them.

But are there signs now?

The crown prince of the Ryukyu Kingdom said excitedly: "In the past, whenever the rice in our country was ripe, they deliberately connived at pirates to rob them------ if we caught the pirates, they sent officials to forcibly ask for them, and we couldn't help but let them go!" ”

Zhang Guoan said in his heart, this is really a jungle world, they are all directly robbed, and the world has not paid as much attention to business spirit as the Great Song Dynasty.

He wants to support Da Song even more!

However, he didn't expect that he would soon join the road of robbery.

He was simply forced. (To be continued.) )
