Chapter 118 Gas Mask
In the smelter, a coke oven stopped, waiting for the new stuff the master was working on.

On the other side, Frederick directed a group of people to fish out the broken wood that had been soaked in the water overnight from the water tank.

These wood chips come from the place where the wood is processed. After being collected, they are first washed in a water tank and the sand and stones in them are deposited, and then soaked in water overnight to absorb the water.

The process of absorbing water was not available when Friedrich's hometown processed activated carbon, because it was to prepare for the next magical processing.

The wet debris was piled up on the cleaned slate floor, and a magician next to them cast a water repelling spell on them.

The free water and absorbed water in the broken wood flew out quickly under the action of the water element, leaving a series of fine holes.

This is a new discovery when the condensed soup factory uses a microscope to study the condensed soup. Increasing the water dehydration rate can leave holes in the dehydrated material, and it can speed up the water absorption when soaking in hot water.

A row of soil tanks with an inner diameter of 25cm and a height of half a meter have been prepared beside them. The workers put the broken wood into it and then closed the lid to seal it.

The sealed clay pots are put into the coke oven, separated from the gap, and then started to ignite.

Alfred, the craftsman of the former blacksmith shop and the current director of the smelter, specially dispatched a set of steam blowers and kiln workers with the best digital technology to fully cooperate with the master's experiment.

Under the action of the centrifugal fan, a large amount of air is blown into the combustion chamber, and the coke drenched with coal tar burns rapidly.

Frederick was a little helpless. The current level of alchemy is limited, and the coal tar produced by coking has little use and can only be used to ignite fire.

Next, first use a high fire to burn the clay pots containing the broken wood until they turn white, then turn the fire to high heat and burn for about 10 hours, then seal the furnace completely and keep it stuffy for about 12 hours.

When the furnace was opened the next day, Frederick brought his secretary Vanessa to the smelter early in the morning. At the same time, Friedrich came to see what the headmaster made to deal with poisonous smoke. BASF brought The experimental equipment customized by the principal, Ogilvy and Schmidt are working here because of steam engine materials, so naturally they will not miss the opportunity to watch the excitement.

Friedrich thought about it and said: "Charcoal? Charcoal can indeed remove some dirt in the water, and can be used to purify water in the wild, but is it really okay to use it to purify the air?"

Frederick watched the workers get into the coke oven and move out the clay pots, and said at the same time: "The charcoal is heated and evaporated by the heat, leaving a lot of gaps, so it can absorb dirt like a towel absorbs water. "

"Now this kind of charcoal has been smoldering for a longer time, and more things are evaporated by the heat, leaving more voids and holes, and more dirt that can be sucked away."

Friedrich nodded and said, "Well, it makes sense."

BASF said on the side: "If slime glue can also be made with such holes, it should be good for filtering water."

Frederick smiled and said, "It would be best if it could be made impermeable but breathable."

At this time, the workers had opened the clay pots, and the broken wood inside had turned into black charcoal.

Frederick told them to move a jar of charcoal to the laboratory.

In the laboratory, BASF took off the sleeves and gloves from the shelf and volunteered to do experiments.

Frederick who was present was the principal, and Friedrich and Ogilvy were professors. He and Schmidt were the only two. Naturally, they did it.

"Schmidt, Schmidt! Come help!!" BASF shouted twice.

Vanessa is from the Kingdom of Sardinia. After working as a secretary next to Frederick, she often met her fellow countryman Katie, so she also dressed in the same style as Katie. The dark gray slim suit set off her beautiful figure.

She has slightly curly brown hair, a high nose bridge, and very moving eyes. Because of her good education and experience working in a bank, she has a particularly confident temperament.

As soon as Schmidt appeared today, he kept focusing on Vanessa. BASF yelled a few times before going over to help with a blushing face.

Following Frederick's instructions, the two of them ground some activated charcoal into powder, and the other added half a cup of water to a beaker, and then added some blue dye.

BASF added a tablespoon of activated carbon powder to blue water and stirred quickly with a glass rod.

After stirring for a few minutes, the water in the beaker became clear again.

BASF added some more dyes, and felt that my hands were tired, so I switched to Schmidt and continued to stir. After a few minutes, the color of the water became much lighter, but then the speed of getting lighter became slower and slower. After about ten minutes, there was still a little blue color in water.

"I'm full of toner." Frederick said with a smile, "It seems to work well."

But Friedrich thought about it and said: "It can absorb so many dyes, maybe it can absorb the toxins in the stomach, and then add a laxative to speed up the discharge."

Ogilvy said to Frederick: "Principal, I think it can be graded by using carbon of equal weight to absorb dyes of different concentrations within a certain period of time."

Frederick replied: "This is also possible, but the purity of the dye must be considered."

Then he turned to BASF and said, "It's time to prepare the instruments you brought."

BASF pointed to something on the other table and replied with a smile: "It's ready, no problem!"

The main part of the instrument he brought is a square pipe more than 1 meter long, made of transparent slime hard glue, with a side length of 10 cm, one side can be opened, and inside are partitions full of holes. The distance between the partitions is 1 cm.

One end of the pipeline is open, and the other end has a cover and a cavity, and a tube is connected to a small bellows on the cover.

BASF and Schmidt put activated carbon particles between the partitions according to Friedrich's instructions. There is an empty compartment between the two layers, and 10 layers of activated carbon are first installed.

After the activated carbon was installed and the cap was tightly sealed, one of them pulled the bellows on one end, and the other tried the wind pressure by hand on the other end.

"Hmm... It seems that there is no problem with the ventilation." Frederick also stretched out his hand to test the wind pressure, "You can light the cigarette."

Friedrich gave BASF a powder that had a pungent smell when burned and was non-toxic. BASF put the powder at one end of the square tube and ignited it, then immediately closed the lid and began to pull the small bellows to blow air.

The white smoke quickly flowed along the pipe to the other end. After passing through the first layer of activated carbon, it immediately became much lighter, and after the second layer, it became even lighter, and after the third layer, the white smoke was no longer visible.

Friedrich put his nose on the other end of the pipe, carefully smelling the air coming out, and said after a while: "It's true that there's no smoke at all, it's all been filtered out."

Frederick asked him: "Is this method effective against poisonous smoke?"

Friedrich nodded and said, "It's possible, but why put so many charcoal particles in front of the nose? It's too thick to make a mask."

BASF immediately replied: "Don't worry, the principal's glass factory has a kind of gas mask. It is equipped with a canister, and the canister is still filled with lye. It is much easier to replace it with carbon particles."

Frederick nodded, and then wrote a note, asking Schmidt to take Vanessa to the glass factory to get some gas masks back.

The glass factory used arsenic to sublimate easily to remove the air bubbles in the glass liquid. Frederick was worried that the workers would be poisoned, so he designed a somewhat complicated canister.

The inhaled air needs to pass through the lye first, and the arsenic vapor in the air will react with the alkali in the water and be removed.

Although it is troublesome to wear a gas mask and hang a can on the back of the waist when working, and it is very troublesome to change it in half a day, so far no worker in the entire factory who abides by the rules and regulations has shown symptoms of poisoning, and the workers have accepted this. Protective measures.

While waiting for the gas mask, Ogilvy reported to Frederick the production progress and plan of the folding shotgun.

Now barrels and spray cans are produced by pressing hot steel blanks into molds under the force of magic muscles, and then further processed by acid etching, so the output has increased.

At present, the production of weapons and ammunition is the first task in the territory. The Springfield Armory and the Lakeside Blacksmith have been working in three shifts for a long time. Ordinary blacksmiths make helmets and cast bullets after receiving the material molds. Even Benz's carriage factory Also take out more than half of the production capacity for military production.

It is expected that by the end of next spring, three to four thousand folding rifles will be produced to equip the main force, the city defense army and the main militia.

Frederick nodded. Everyone has worked hard, and he can't be too demanding.

The gas mask from the glass factory was quickly brought back. After studying it for a while, Friedrich said: "This is not enough to cover the mouth and nose, but also to cover the eyes."

"No problem, I will change the design." Frederick replied. He used a military gas mask in his previous life. He had to pass an assessment when he was a militiaman, and he had to take it out and wear it at a specified time.

The corrugated hose that connects the mask to the canister is fine, and the canister will naturally have to be redesigned.

They discussed for a long time in front of the square pipe that they had just experimented with, and finally decided that the breathing tank was made of metal, the iron cover at the front had several air intake holes, and elastic film was used as a one-way valve.

The first layer of filtration is two layers of cotton cloth sandwiched with absorbent cotton to filter out large particles.

The second layer uses activated carbon with a thickness of about 10 cm as the main filter material, which is enough for a day.

After the initial finalization, Ogilvy will organize the production of several pairs, and then gradually change them.
