Although the back playground of the primary school is not the boundary of the town’s houses, it is already a super remote place. There is no way to go further. There is only a row of houses below, which belongs to the unit building of the substation.

After dinner, Fang Dajun and Han Mei's family took the materials they wanted to use for the test and went straight to the side of the playground. There was a small piece of obvious burning traces there. It was probably the place where Han Mei's previous tests were conducted.

The simplest honeycomb coal is to crush the raw coal and mix it with yellow soil. If it is a little bit dark, it will mix with unburned coal sand. It is a very deceptive species, because not only is the ignition point of coal, but the better the coal, the higher the ignition point. For example, the ignition point of anthracite is between 500-700C. Of course, it is not easy for you to ignite garbage coal no matter what you do.

It often takes half an hour or even longer for villagers to make fires with coal at home, and the initial honeycomb coal is similar.

The heart of corn's cob is the treasure for villagers to make fire, which is more convenient than wood. For primitive honeycomb coal, you may not be able to ignite it even if you burn it with an 800-page book. The towns cannot find corn cobs, so you can only use wood or seriously polluted plastic to make fire. Often, the house is chaotic, which is just a fire. After the fire is ignited, you will find that the flame burned by honeycomb coal is very weak. In addition to being cheap, it is really not easy to find advantages.

The honeycomb coal in later generations was relatively excellent. There was no pressure to open a restaurant or host a banquet. Fang Dajun came here for this.

Having talked for a while, Han Mei went straight to the topic and said, "The teacher has experimented with a few recipes, look at the results and choose one."

Then Han Mei took out several formulas, such as the ignition layer: **30% (oxidant), potassium nitrate 1.7% (oxidant), potassium 0.9% (catalyst), wood carbon powder 17.4% (low-ignition point carbon material), anthracite 30% (high-carbon-based material), carbonized sawdust 13%, oxidized black 2% (purifier) ​​yellow mud is about 3~5% (binder). The ignition layer: 23% carbonized saw wood layer, 15% wood carbon powder 50%, anthracite 3%, calcium oxide 3%, and yellow mud is about 4~9%. The ignition layer at the bottom layer accounts for 20%, the ignition layer in the middle accounts for 20%, and the main coal above accounts for 60%.

For example, 25% strontium nitrate, 9% potassium peroxylate, 5% saltpeter, plus carbon powder, 2% cement powder, 3% saltpetite, 5% tanninic acid, and 3% organic waterproof coatings are used as the ignition layer. For example, 30% barium sulfate (oxygen aid) (potassium nitrate) (1.7% potassium permanganate (catalyst) (0.9% wood carbon powder (low-ignition point carbon-based material) (17% carbonized sawdust (low-ignition point carbon-based material) (13% anthracite (high-carbon-based material) (30% anthracite (high-carbon-based material), calcium chloride (purifier, also known as lime powder) (2%, iron trioxide (purifier) ​​(1.7% binder), etc. as ignition agent, etc.

Finally, Fang Dajun chose several cheap materials ready-made in the village, such as carbonized sawdust, lime, red (yellow) mud, charcoal powder and other mixtures, base materials and flammable combustible aids such as X nitric acid and potassium permanganate.

There are many wood chips in carpenters' houses, and charcoal can be solved by native methods. The villagers store charcoal (cracker) at home. The lime is just burned out with limestone, and mud is everywhere. These are almost not included in the cost. After adding cheap base materials, oxidation, combustion, purification, etc. are complete.

The honeycomb coal produced in this way is fast to heat up, the theoretical flame can reach more than 14CM, the theoretical combustion time can be as long as one hour, it is smokeless and odorless, and can burn completely and thoroughly.

One hour of burning time is enough for cooking, and of course there are better recipes, but from the perspective of production, we can only give up at present. In addition, no matter how good the thing is, if there is no upgrade version for a long time, it will be unfavorable to market sales.

After the general direction was set, a few people started to make it on site. It seemed a bit complicated, but everything had manual test items, and it was not purely manual mass production. It would be solved by taking a little time.

"It's done, it's really good!" Fang Dajun was extremely satisfied with the flame burning from the coal balls. He just used a little paper shell to ignite the fire. The point of ignition alone was suitable for popularization, and the flame burning was also very powerful, and there was no pressure to cook at home.

Of course, the most accurate data needs to be tested in the furnace, because the honeycomb coal in the furnace is placed overlapping, and the ventilation openings below are also divided into sizes, just like the fire door of the earth stove. The more ventilation, the greater the firepower, and conversely, the smaller the firepower.

The rest are of course putting on the pot for cooking experiments, and these are the side branches and the last sections. According to his judgment, such a formula is completely sufficient for production.

It seems that it is really right to look for Han Mei. It is not the other way. It is just some chemical base materials used, and it is not easy to buy them even if others can think of them. However, Han Mei can use the excuses of doing experiments for students to solve the problem, or directly connect to the school's purchasing staff.

"It's still true. Although it's not the best I've tested, it's easier to produce." Han Mei was also very satisfied with this. Her man Yi Mulin was also happy. Because honeycomb coal became a result, his full-time problem had the opportunity to solve it. The elementary school substitute teacher was appointed as a formal junior high school teacher who was very famous in the local area. His dignity pressure has been very high over the years.

The child clapped his hands happily. He probably didn't understand why adults would play with fire, but for children, having delicious food and fun is not a happy life.

Fang Dajun was happy, and then chatted with Han Mei. After waiting for more than twenty minutes, the flames gradually became smaller. It was not because the combustion lasted for a long time, but because the coal balls burned open air, ventilated on all sides, and wasted fire, so they naturally burned quickly.

"Teacher Han, let's clean up here first. Now you will write me the most detailed recipe, and also talk about what you plan to invest in money." Fang Dajun went straight to the point, which means that he agreed to join Han Mei. He could not become a super rich by selling honeycomb coal alone. This is just the first step, and there is no need to eat alone.

"Okay!" Han Mei's face was even more joyful. If she wanted to invest in an impulse before, but after testing the actual effect of honeycomb coal, her investment intention became even stronger.

The scene changed, and the child Dongdong was ordered to play, so as not to go out and say something after hearing the message. Fang Dajun and Han Mei and his wife were talking in the living room.

"Teacher Han, let me first talk about how much money you can spend?" Fang Dajun asked the key point directly. If the money is too little, then there is no need to waste his saliva and he will only give the other party the right to dividends. As for management, it is not suitable.

Han Mei gritted her teeth and said, "Two thousand yuan integer."

"So much?" Fang Dajun seemed a little surprised. Han Mei's salary was not high. Yi Mulin's salary was mostly spent on family expenses. Two thousand yuan is not a small amount. Maybe in a few years, this money will be relatively easy to make, but now everyone has no spare money.

"The teacher asked his relatives to collect it. Now there is only more than 700 cash. The rest will be collected by the end of the month." Han Mei explained.

Fang Dajun nodded and then said, "I plan to invest 10,000 yuan in the overall investment of honeycomb coal, of which about 7,000 yuan will be spent on machinery and equipment sites, etc. The remaining amount is used to purchase raw materials and early wages, as well as some units and individuals who like to take credit, so the profits in the previous period may be on the books, and 10,000 yuan can no longer be reduced."

"Who else invested?" Han Mei was not scared by the 10,000 yuan, but felt that only such a big investment could be successful, and she would not make a lot of money by making small fuss.

"Secretary Wang of Jiaoshan Commune and me." Fang Dajun smiled.

"It turns out to be Secretary Wang. No wonder you are so confident. But how much do you plan to invest in?" Han Mei is also a flexible person. Of course, Secretary Wang is the best to join in, but if Secretary Wang is the leader, her investment will be a bit embarrassing, and she will be unable to speak of profits in the future.

"I will invest at least 4,000, or 5,000 yuan. I will talk to Secretary Wang about the specific amount, and at least I will ensure that the investments of our two parties will exceed those of Secretary Wang. Teacher Han, let me be honest, we are a teacher-student relationship, and we will be on the same line in the future." Fang Dajun named the trick.

Han Mei replied happily: "The teacher is just about to talk about this problem. Secretary Wang is an official. If we really make trouble, we can't beat him."

"Well, I have to control the investment. Later, I will register the honeycomb coal as a regular enterprise. With legal protection, there is no need to worry about these issues. In the early stage, everyone can have a clear mind." Fang Dajun explained confidently. He was not worried about the issue of distribution. Now, he said this, in fact, it was relying on the black Wang Hongwen to enhance the cooperative relationship between him and Han Mei.

Then we talked about the specific distribution, "Teacher Han, there is another question I must make clear, investment is investment, wages are wages, and relationships are relationships. These issues need to be understood. For example, Secretary Wang made efforts here and used relationships; For example, I participated in unified management, these will be considered a profit distribution, and these will be directly deducted from the profits, and then dividends will be distributed according to the investment ratio. Of course, the specific amount will be decided by the three parties after discussion. Can you understand?"

This is different from family businesses. Profits must be calculated separately from their efforts. As long as individuals pay, wages should be calculated based on the value of their labor, regardless of the identity of the person.

Of course Han Mei could understand, but she also asked: "Can you arrange for relatives to go in?"

Fang Dajun thought about it and found that this problem could not be eliminated. "Yes, it is given priority under the same conditions, but if relatives mess around, they will also be fired. This issue will be discussed in detail at that time."

"It's true, then I'll have no problem." Han Mei was quite satisfied with Fang Dajun's answer. Her and Dajun's investment combined exceeded that of Secretary Wang, and she could arrange relatives to go in so that she would not be completely unclear about production and sales. As for the expenses in relationships and management, she would also participate in the discussion at that time.

Fang Dajun thought for a while and said, "In the early stages, I will gradually formulate rules and regulations. I hope you can support me when the time comes. If the factory wants to make money for a long time, it must have a rigid system."

"Sure, the teacher can trust you." Han Mei agreed readily. She borrowed such a large amount of money. If she lost money, the couple would have to pay back many years of debt. If they made money, they would of course hope to make a longer profit.

"Haha, that's good. The time is almost over. Teacher, please write down the recipe in detail, and I will go back to the commune. After contacting the production equipment, the three of us will discuss the details together. There is no hurry to make money, but you must also prepare it, because the machine is purchased outside and it is impossible to take credit first." Fang Dajun finally summarized it.

In the middle of the afternoon, he took the recipe back to the commune. The construction of the vermicelli farm is inseparable from him. As long as the construction starts, he has to take care of it every day.
