With cement, the construction of chemical plant buildings is relatively easy.
Of course, building walls with cement is also a technical job.
The construction team took the opportunity to introduce the old to the new and sent a large number of novice naturalized citizens to the construction site for learning.
This point made Fang Xiaoyue a little dissatisfied at first.
Fortunately, the technical content of cement wall building is not high, and the new naturalized residents also studied very hard and mastered this technology in a short time, and there were no construction accidents.
However, it is currently impossible to fully build a chemical plant.
Fang Xiaoyue first built several workshops for the production of three acids and two alkali.
The preparation method of nitric acid has been mentioned before, so there is no need to mention it again.
Sulfuric acid is much easier than nitric acid in Fang Xiaoyue's hands.
The simplest way is to burn the sulfur recovered from the steelmaking plant into sulfur dioxide. In the subsequent processes, concentrated sulfuric acid and dilute sulfuric acid are different.
Needless to say, Fang Xiaoyue feels that it is much simpler than nitric acid.
Hydrochloric acid is even simpler.
Saturated brine is electrolyzed to obtain not only caustic soda, but also hydrogen and chlorine. Then hydrogen and chlorine burn and react to generate hydrogen chloride, which is absorbed by water to form hydrochloric acid.
With caustic soda, it is simple to prepare soda ash.
This is why the first industries created in the dock area were related to saltworks.
If there is no salt field, if you want to prepare hydrochloric acid, caustic soda, etc., you need to spend money to buy it from outside. These years, with the invasion of the Qing army, many salt fields were abandoned and a large number of salt workers were displaced.
Regardless of whether it was the areas occupied by the Qing army or the Nanming area, the price of salt was rising steadily.
Moreover, the waste brine produced in the salt farm can also be used to industrially prepare magnesium metal and chlorine gas. The chlorine gas can also be used to prepare hydrochloric acid. Needless to say, magnesium metal is a good thing!
Magnesium metal is originally one of the lightest structural metal materials, with high specific strength and specific stiffness, good damping and cutting properties, and easy recycling. Therefore, magnesium alloys have been widely used in the automobile industry in later generations.
And if future generations want to obtain high-quality steel, they generally use magnesium powder for desulfurization.
In addition, magnesium, as a sacrificial anode, is used in pipelines, ships, offshore facilities, equipment, etc., and can play an important role in preventing metal corrosion.
The most critical point is that magnesium plays an important role in the military.
A long-term floating artillery flare, made of magnesium powder.
Incendiary bombs need to contain magnesium powder.
Planes, tanks, ships and even aerospace all use magnesium alloys as structural materials in large quantities.
Not to mention anything else, these two points, flares and incendiary bombs, are important enough for today's team training.
Flares can ensure visibility during team training night battles in the dock area.
Incendiary bombs are the most lethal weapon in naval warfare in this era!
If you think about it, you will know that all naval warships in various countries in this era are made of wood.
Although the top warships of some naval powers are made of teak, there is no need to worry about being hit by a red-hot iron ball and burning the ship directly.
But if incendiary bombs mixed with magnesium powder are used, it is estimated that a battleship can be easily burned down with one bombardment.
Under the busy work of Fang Xiaoyue and others, various reaction towers, pipes, and storage tanks were formed bit by bit.
At this time, the reconnaissance team deployed outside sent back new news.
The Thousand Households in front of the Wei and the Thousands of Houses in the Zuo have sent out troops!
Perhaps they got the news that the entire army of Weiyou Qianhu Station was destroyed. This time, the two Qianhu Stations joined forces before heading towards the dock area. After careful observation by the reconnaissance team, the total force reached
An astonishing two thousand people!
Well, in fact, according to the judgment of Sun Xuebin and others, even if the two Qianhu Stations are squeezed out of their oil, it is impossible to come up with two thousand troops, unless the officials of the Qianhu Stations do not eat empty pay.
Don't drink the blood of soldiers.
But is this possible?
How can those officials in Qianhusuo be able to raise beautiful concubines and a large group of servants if they don't eat free wages and drink the blood of soldiers? How can they enjoy a life of plenty of food and fish every day?
But this time, two thousand households sent two thousand troops!
Of course, no matter what, since the opponent's troops are united, it actually reduces the defense burden in the dock area.
Instead of having to deal with two groups of enemies before, there is now one.
This time Sun Xuebin was still the commander-in-chief of the campaign.
Compared with the last battle of Beauty Ridge, more troops were sent to the dock area this time, with two battalions and more than 570 people dispatched.
The same large trucks were delivered, and more artillery was delivered.
However, since the Ming army chose Chengmai as the place to send troops after joining forces, Sun Xuebin decided to attack at Meichao between Chengmai and the dock area.
Meichao is actually a small piece of plain, which in later generations was one of the rare granaries on the island.
There is a village here now.
After Sun Xuebin arrived, he immediately had the village sealed off, and with the village as the core, the soldiers dug trenches and built parapets.
Although the parapet tactic was not used in the previous battle of Meirenling due to the stupidity of the opponent Qianhu, this did not extinguish Sun Xuebin's thoughts.
No one knew that Sun Xuebin had an unimaginable passion for lining up to be shot.
Of course, he also knew how much loss he would suffer to the soldiers he had worked so hard to train if he really lined up and shot him.
After all, even those Ming armies still have archers. If you stand there, you might be hit by an arrow.
However, it is different if there is a parapet, which can at least block most of the arrows or bullets fired from firecrackers.
At the same time, I can barely satisfy my desire to queue up and shoot.
Due to the availability of large trucks, nearly 600 soldiers led by Sun Xuebin built parapets and trenches around the village early.
The trench is right behind the parapet. The soldiers stand in the trench with their shoulders just exposed, and the muzzle of the gun is only about fifty centimeters from the ground, which can better ensure the hit rate.
After all, the Thunderbolt 1646 rifle has an inconspicuous flaw, which is that the muzzle tends to float slightly when the trigger is pulled.
Under such circumstances, if soldiers are not familiar with firearms, their hit rate will be very low.
Sun Xuebin's parapet trench tactics perfectly made up for this.
In addition, even if the shooting is accurate, the bullet fired from 50 centimeters above the ground will hit the enemy's leg.
In this case, it will be easier to capture more enemies.
As for minor operations such as removing bullets, Wang Delun's intern doctors can perform them. As long as they are disinfected with alcohol, the mortality rate can be greatly reduced.
Sun Xuebin stood on the top of a house in the village, looking into the distance with a telescope.
There are plains around here, so the telescope can see very far.
Now that all combat preparations are done, we are just waiting for the Ming army to invade.
