Although the back yard of the elementary school is not considered the boundary of the town's housing construction, it is already a super remote place, and there is no way forward, only a row of houses below, which belongs to the unit building of the substation.

After the meal, Fang Dajun and Han Mei's family carried the materials to be used for the test directly to the edge of the field, where there was a small trace of obvious burning, which was estimated to be the place where Han Mei had tested before.

The simplest honeycomb coal is the raw coal after crushing and adding yellow clay to mix, the black heart will also be mixed with the coal sand layer that cannot be burned, which belongs to the very cheating variety, because the coal not only has a high ignition point, and the better the coal, the higher the ignition point, such as the ignition point of anthracite coal is 500-700c, of course, garbage coal is not easy to ignite no matter how you do it.

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

The cob of corn is a treasure for the villagers to make a fire, which is more convenient than wood, and the original honeycomb coal, you just take an 800-page book and burn it to the fire, and the town can't find the cob of corn, so you can only use wood or polluting plastic to make a fire. Often make the home into a miasma, this is just a fire, after the fire is lit, you will find that the flame of honeycomb coal burning is very weak, in addition to the cheap, it is really not easy to find advantages.

The honeycomb coal of later generations is relatively good, it is used to open a restaurant, and there is no pressure to host banquets, and Fang Dajun is here for this.

After chatting for a while just now, Han Mei went straight to the point and said, "The teacher has experimented with several recipes, you can choose one based on the results." ”

Then Han Mei came up with several formulas, such as the ignition layer: **30% (oxidant), potassium nitrate 1.7% (oxidant), potassium 0.9% (catalyst), wood toner powder 17.4% (low ignition point carbon material), anthracite 30% (high carbon-based material), carbonized sawdust 13%, oxidized black 2% (purifying agent) yellow mud is about 3~5% (binder). Ignition layer: 23% carbonized sawn wood layer, 15% wood toner, 50% anthracite, 3% calcium oxide, and about 4~9% yellow mud. The ignition layer at the bottom accounts for 20%, the ignition layer in the middle accounts for 20%, and the upper body coal accounts for 60%.

Another example is the use of 25% strontium nitrate, 9% potassium peroxide, 5% saltpeter, plus carbon powder, 2% cement powder, 3% saltpeter, 5% tannins, and 3% organic waterproof coating as the ignition layer. Another example is the use of barium sulfate (oxygen aid) 30%, potassium nitrate (oxygen aid) 1.7%, potassium permanganate (catalyst) 0.9%, wood toner (low ignition point carbon-based material) 17%, carbonized sawdust (low ignition point carbon-based material) 13%, anthracite (high carbon-based material) 30%, calcium chloride (purifying agent, also known as lime powder) 2%, iron trioxide (purification agent) 1.7%, adhesive and so on as ignition agent.

In the end, Fang Dajun chose several cheap materials that were readily available in the village, such as carbonized sawdust, lime, red (yellow) mud, charcoal powder and other mixtures, and the base material was composed of flammable accelerants such as X nitrate and potassium permanganate.

Sawdust is more in the carpenter's house, carbonization can also be solved by soil methods, charcoal (dry charcoal) villagers are stored in the house, lime is directly burned out with limestone, mud is everywhere, these are almost not included in the cost, after adding cheap base materials, in this way, oxidation, combustion, purification and so on are complete.

The honeycomb coal made in this way can fire quickly, the theoretical flame can be as high as 14cm, the theoretical burning time can be as long as one hour, smokeless and tasteless, and can be completely and thoroughly burned.

One hour of burning time is enough for cooking, and of course there are better recipes, but for production reasons, we can only give up for now. In addition, no matter how good something is, if it has not been upgraded for a long time, it is not good for market sales.

After the general direction was set, several people began to make it on the spot, which seemed to be a little complicated, but everything has handmade test products, and it is not a pure manual mass production, so it will be solved with a little time.

"It's done, it's really good!" Fang Dajun was extremely satisfied with the flames from the burning briquettes, and it took a few minutes to ignite the fire with a little paper shell, just starting the fire is already suitable for popularization, and the flames that burn out are also very powerful, and there is no pressure on home cooking.

Of course, the most accurate data has to be tested in the furnace, because the honeycomb coal in the furnace is placed on top of each other, and the vents below are also divided into sizes, just like the fire door of the earthen stove, the more ventilation, the greater the firepower, and vice versa, the smaller the firepower.

The rest, of course, was to be put on the pot for cooking experiments, and these were all side points, and in his judgment, such a recipe was completely sufficient for production.

It seems that it is really right to find Han Mei, first of all, it is not easy to buy all the chemical base materials used, even if others can think of them, but Han Mei can use excuses such as experimenting with students to let the school solve it, or go directly to the school's procurement staff.

"It's not the best in my experiments, but it's relatively easy to produce." Han Mei is also very satisfied with this, her man Yi Mulin is also happy, because the honeycomb coal has become, his problem of becoming a regular teacher has a chance to be solved, and the identity of a substitute teacher in the primary school has taken a regular junior high school teacher who is very famous in the local area, and his dignity has been under great pressure over the years.

The child Dongdong clapped his hands happily, he probably didn't understand why the adults would burn the fire to play, but for children, there is delicious food and fun, isn't it a happy life.

Fang Dajun was happy, and then chatted with Han Mei, and waited for more than 20 minutes, the flames gradually decreased, not because the burning was long-lasting, but because the briquettes were burning in the open air, ventilated on all sides, and the firepower was wasted, so they naturally burned quickly.

"Teacher Han, then let's clean up this place first, you can write me the most detailed recipe now, and also talk about the things you plan to invest money in." Fang Dajun went straight to the point, which meant that he agreed to Han Mei joining, he couldn't become a super-rich man just by selling honeycomb coal, this was just the first step, there was no need to eat alone.

"Good!" The joy on Han Mei's face was even stronger, if she wanted to invest in impulsive ingredients before, but after testing the actual effect of honeycomb coal, her intention to invest was even stronger.

The scene changed, the child Dongdong was called out to play, lest the child go out and say something after hearing the information, Fang Dajun and Han Mei were talking in the living room.

"Teacher Han, tell me how much money you can come up with?" Fang Dajun directly asked the key point, if the money is too small, then there is no need for him to waste saliva, and he will only give the other party the right to dividends, as for management, etc., it is not appropriate.

Han Mei gritted her teeth, "Two thousand yuan as an integer." ”

"So much?" Fang Dajun looked a little surprised, Han Mei's salary is not high, most of Yi Mulin's salary is spent on family expenses, two thousand yuan is not a small amount, maybe in a few years, this money is relatively easy to get, but now everyone has no money left.

"The teacher asked his relatives to make it together, and now he only has more than 700 cash, and the rest will not be available until the end of the month." Han Mei explained.

Fang Dajun nodded, and then said: "The overall investment in honeycomb coal I plan is 10,000 yuan, of which about 7,000 yuan will be spent on machinery and equipment, etc., and the rest will be used to purchase raw materials and pay wages in the early stage, as well as some units and individuals like to take credit, so the profits in the previous period may be on the books, and 10,000 yuan can not be less." ”

"Who else is investing?" Han Mei was not only not frightened by 10,000 yuan, but felt that only such a big investment could see success, and a small fight would not make a lot of money.

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

"It turned out to be Secretary Wang, no wonder you are so confident. But how much are you going to put it in? "Han Mei is also a flexible person, of course it is best for Secretary Wang to join in, but if Secretary Wang is the leader, her investment will be a little embarrassing, and it will not be possible to say anything about profits in the future.

"I will invest at least 4,000, or 5,000, and I will talk to Secretary Wang about the specific amount, at least I will ensure that the investment of the two of us will exceed Secretary Wang. Teacher Han, let me say something from my heart, we are a teacher-student relationship, and we will be on the same line in the future. Fang Dajun named one of the doorways.

Han Meile replied: "The teacher is also about to talk about this problem, Secretary Wang is an official, and if it really makes trouble, we can't fight him." ”

"Well, hold on to the investment, and register the honeycomb coal as a regular enterprise in the back, so you don't have to worry about these problems with legal protection, and everyone can have a psychological bottom in the early stage." Fang Dajun explained with confidence, he didn't worry much about the distribution, and now that he said this, he was actually relying on Black King Hongwen to enhance the cooperative relationship between him and Han Mei.

Then he talked about the specific distribution, "Mr. Han, there is another question that I must make clear, investment is investment, salary is salary, relationship is relationship, these problems should be understood separately." For example, Secretary Wang contributed to this and used relationships; For example, I participated in the unified management, these will be counted as a benefit distribution, these will be directly deducted from the profits, and then according to the proportion of investment dividends, of course, the specific amount, will be decided by our three parties after discussion, can you understand? ”

This is different from a family business, where profits must be calculated separately from contributions, and as long as an individual has to pay, wages should be calculated according to the value of labor, regardless of the person's status.

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

Fang Dajun thought about it for a while, there was no way to put an end to this problem, "Yes, under the same conditions, priority will be given, but if relatives mess around inside, they will also be expelled, and this issue will be discussed in detail at that time." ”

"Okay, then I'll have no problem." Han Mei is still quite satisfied with Fang Dajun's answer, she and Dajun's investment together exceeds that of Secretary Wang, and she can arrange for relatives to go in, so that she will not be completely unclear about the production and sales situation, as for the relationship and management expenses, she will also participate in the discussion at that time.

Fang Dajun thought for a while, and then said: "In the early stage, I will gradually formulate rules and regulations, and when the time comes, I hope that you will support you, teacher, if the factory wants to make money for a long time, it must have a hard surname system." ”

"Cheng, the teacher can trust you." Han Mei readily agreed, she borrowed such a large amount of money, if she lost her capital, the two of them would have to repay the debt for many years, and make money, of course, I hope to earn it longer.

"Hehe, that's good, it's almost time, teacher, you write out the recipe in detail, and I'll go back to the commune." After contacting the production equipment, the three of us will discuss the details together, and the money is not in a hurry, but you must also be ready, because the machine is purchased outside, and it is impossible to pay on credit first. Fang Dajun finally summed it up.

In the middle of the afternoon, he went back to the commune with the formula, and the construction of the vermicelli farm was inseparable from him, and as long as the construction started, he had to take care of it every day.

ps: I'm back in the city, and it's still comfortable to use on a desktop!
