After Zhang Guoan woke up the next day, he felt refreshed and full of energy. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

He feels like a college graduate now, and he is full of hope for his future.

He is certainly not a brain-dead young man who blindly believes that the future will be better.

Because of his actual age, no one or organization in this world can brainwash him or deceive him.

And because the reality is in front of him, if you want to live a good life, you have to create it yourself------ so he is not tired of working at all, everything is for himself.

When he arrived at the wood processing plant, he asked for the immediate manufacture of several small chute beneficiation equipment, that is, the miniaturization of the original iron ore beneficiation equipment.

In this way, two people can operate, one person feeds, and one person flushes.

The wood mill is very busy, and all the woodwork is produced here, but luckily they have a woodworking machine.

Zhang Guoan looked around, felt that everything was normal, and left.

When he arrived at Bayou Castle, he saw Captain Bowie and the other half-grown boys leading the team in training, and they were very serious.

He summoned Captain Bao Wei and said: "I will give you an order now, except for the ten of you, the other team members will immediately be sent to the area of a river estuary to report to Deputy Captain Guo Beyu, and then the ten of you will pick out three hundred people from the van soldiers and retrain a team like this------ do you have the confidence?!" ”

Captain Bowie was reluctant to do so, but he would definitely listen to the Lord's orders.

"Yes, Lord! I'm confident! ”

Zhang Guoan added: "Don't pick ------ from among the craftsmen"

"Yes, Lord!"

Zhang Guoan saw Captain Bao Wei running to prepare, and thought to himself, four or five thousand people, but the guard team suddenly expanded to six hundred. More than 10 percent!

This is properly a militaristic state----- they can only rely on so-called high-tech products to feed them.

Zhang Guoan went to the construction site again.

This building is actually a multi-service building built on one side of the castle, so that some building materials can be saved.

Zhang Guoan found the master craftsman who originally built the castle and asked him to organize manpower and building materials, and immediately go to the mouth of a river to build another such castle.

The master craftsman said, "Zhang Bow, if you take away the building materials." It's going to stop work here------"

Zhang Guoan knew his current level of productivity, and said: "Go ahead, stop work here first, military needs are greater than all ------"

The master craftsman immediately went to prepare.

This time, he only recruited one workshop to steam camphor and harvest rosin, and as a result, the camphor and pine fragrance emitted by this family and his original workshop made people smell it from a long distance.

In Zhang Guoan's workshop, he used a copper pot distillation pot. And set up a wooden steaming barrel on the steaming stove, which is consistent with the size of the pot. Set on top of the pan.

When processing, the camphor leaves or camphor wood flakes are packed into a steaming bucket, and the water in the pot is separated from the raw materials by 10 cm. Close the lid and charging port immediately after feeding, and then let the craftsman check the connection between the distillation pot and the cooler, if there is no air leakage, the distillation can begin.

When distilling, the water level in the pot should be maintained to prevent it from drying out or burning. The water after the separation of oil and water is used as the return water. Return to the steamer.

The vapor with camphor and camphor oil is cooled and separated through the air duct into the multi-ring disc cooler. After condensation, the camphor and oil should float on the surface.

The separated water should be transparent, if it is opaque, it should be separated again, which can improve the oil yield.

The camphor and camphor oil floating on the surface of the water can be filtered with gauze. That is, the crude camphor is obtained, and the remaining camphor oil contains most of the camphor, that is, camphor oil.

When extracting camphor oil from camphor oil for re-evaporation and purification, the camphor oil can be placed in the distillation pot. Secondary distillation is carried out, the distillate is collected, and the crystalline camphor is precipitated after cooling.

The cooler is also simple in structure, and it is easy to build by a blacksmith.

However, the methods of the craftsmen of the recruited workshops were too stupid. They also slice the roots of the camphor tree, and then soak them in water for three days and three nights, and then use more than a dozen copper pots to decoction, and then several craftsmen have willow sticks to stir frequently, and when there is hoarfrost on the willow sticks, they will filter out the slag and pour it into the clay pot, and after one night, there is naturally camphor precipitation in it.

Cut the pine oil and then suffer, everyone is much the same.

There are camphor trees on Liuqiu Island, but the methods of those craftsmen are too wasteful, and they also pollute the environment.

Zhang Guoan found the workshop along the way, and said to the master craftsman and workshop owner: "Your method is too stupid, and the yield is low!" ”

The guy threw his hand and said, "That's why camphor will be expensive." ”

Zhang Guoan snorted angrily and said, "You didn't go to my workshop to have a look? ”

"I haven't ------ my family has used this method for generations------ but fortunately, it is really camphor roots in this place, and I don't need money."

This is the first time Zhang Guoan has met a Great Song Dynasty craftsman who does not want to learn.

"Go and see now, I have ten times as much production there as you, and I only use a few people."

The fellow threw up his hand again and said, "Well said, well said, I'll go after I've finished cooking this pot!" ”

Damn, as if I begged you, Zhang Guoan left not very happy.

He needed a large amount of camphor, which was to prepare him for the processing of the single-base firearm propellant shortly after.

The single-base fire gun propellant is basically made of nitrocellulose plasticized with alcohol ether solvent.

After plasticization, the nitrocellulose cotton will become similar to the dough, and then processed into various shapes of single-base firearm propellant, after its forming, it must be finally treated with camphor as needed, camphor is the best retardant, the camphor is added to the surface layer of the single-base firearm propellant, so that its content is continuously reduced from the surface and the inside, and the combustion rate during combustion is continuously increased from the surface and the inside, forming a gradual combustion, and the driving force is increased, which is required by the long-tube firecracker.

Camphor would occupy one-tenth of the single-base firearm propellant, so he had to find a way to develop the camphor business.

In addition, it is also needed for the manufacture of explosives.

Later, it was even more needed to make celluloid, and at that time, he would make breech guns that used celluloid as cartridge cases.

Celluloid shells can be made by hanging tin to ensure that they are not deformed.

This is Zhang Guoan's requirements for the camphor cause.

When he was considering whether to expand his camphor business on his own and could no longer rely on the help of the Great Song Workshop, the good news suddenly came that the last fleet that had gone to sell salt had returned.

Zhang Guoan hurried to the dock, and sure enough, he saw a team of sea boats sailing into the dock smoothly.

When the first ship docked, the captain said to Zhang Guoan: "Captain Zhang, I have fulfilled your request, this ship is full of cotton, cotton and good iron, and I have also brought craftsmen hired by myself------ this is the list of transactions." ”

Zhang Guoan took the list, frowned, and said, "Why is the price of this sea salt low?" ”

The captain said, "The people of the city department said that there was a lot of sea salt, and they were afraid that it would not be easy to sell it, so they lowered the price, but they added a little more refined salt, so that they came back with so much goods." ”

Zhang Guoan nodded, this is the benefit of monopoly management, he said: "Has the price of salt in Lin'an City dropped?" ”

"Heh, heh, I also dropped a few pennies------"

Well, the Great Song government still has a conscience. (To be continued.) )
