Siheyuan: Start as a truck driver

In addition, the technical content of hand warmers is not high, Wang Weidong can completely copy it.

Anyway, hand warmers were invented by the island country in the 1970s, and Wang Weidong pirated them without any guilt.

Moreover, the cost of hand warmers is low, and the heating ingredients are iron powder, activated carbon, non-metallic mineral powder and salt, which are not considered controlled resources.

It is not difficult to mass produce.

Previously, Wang Weidong felt that his current position was very embarrassing.

If you want to change the status quo, the best way is to come up with a product that can be quickly promoted and occupy the market.

I originally thought of a hot water bottle, but now it seems that this warm patch is more suitable.

Wang Weidong explained the principle and structure of hand warmers to Jiang Deming.

The second-hand scientist looked surprised at first, then his eyes flashed with admiration.

How smart is this truck driver!

In front of Wang Weidong, Jiang Deming felt that he was just a primary school student.

...

Man, just do it!

The two discussed it, made a list of materials, and went to Director Yang's office together.

Director Yang frowned as he looked at the materials list. How much money would it cost to have so many materials?

However, I heard that the two of them were manufacturing low-cost hand warmers, so without saying a word, they issued a letter of introduction needed to purchase the materials.

After all, he had seen the effect of hand warmers with his own eyes.

Ever since my wife started using the hand warmers, her legs never got cold again. She climbed the third floor in one breath without breathing heavily.

Awesome!

In the courtyards in the capital, there are many old comrades who have gone through hard times. Most of them suffer from cold legs, rheumatism, arthritis and other diseases.

Factory Director Yang was still thinking about how to ask Wang Weidong to make more hand warmers, but this guy actually invented another hand warmer.

Moreover, the cost of hand warmers is very low and can be produced in large quantities.

Must support!

...

After holding the letter of introduction, Wang Weidong and Jiang Deming rode a bicycle to the industrial materials store near Gongzhufen.

When the saleswoman who was knitting a sweater saw the letter of introduction, she looked them up and down, asked them to take out their work ID cards, and checked and interrogated them in detail.

If she hadn't considered it too expensive to call, she might have called the rolling mill to check.

After finally confirming that these two people could not be enemy agents, the saleswoman turned and walked into the warehouse.

That serious and responsible attitude made Wang Weidong sigh that people in this era are really highly vigilant.

Ten minutes later, the saleswoman took out the iron powder and activated carbon.

With these materials, Wang Weidong and Jiang Deming went to the Chinese medicine shop and bought a medicinal material called vermiculite.

Vermiculite is a natural, inorganic, non-toxic mineral that expands when exposed to high temperatures.

It can replace non-metallic mineral powder in raw materials.

Since ancient times, everything can be treated with traditional Chinese medicine.

Take the excrement of animals for example. The excrement of flying squirrels is Wulingzhi, the excrement of bats is luminous sand, the excrement of wild rabbits is lunar sand, the excrement of sparrows is white lilac, the excrement of pigeons is Zuolongpan, and the excrement of horses

It's Baimatong.

Of course, many minerals are no exception and can be used as traditional Chinese medicine.

Materials are scarce these days. When scientific researchers lack experimental materials, the first thing they think of is traditional Chinese medicine stores.

It only took less than two hours for the two of them to purchase all the materials for making hand warmers.

The whole process was extremely smooth.

The only thing that made Jiang Deming feel uncomfortable was that Wang Weidong, who was sitting on the back seat of the bicycle, seemed to have a rocker in his waist.

The rocker always pokes him in the back.

It hurt a lot.

Jiang Deming grinned all the way, with a look of pain on his face.

This truck driver is really dedicated and carries the crank handle with him wherever he goes.

...

After gathering the materials, start summoning the dragon.

Pooh!

It's about making hand warmers.

The production process of hand warmers is simple. Under the guidance of Wang Weidong, second-hand scientist Jiang Deming made it effortlessly.

After the iron powder on the experimental table comes into contact with humid air, under the action of salt, a chemical reaction occurs rapidly, forming iron hydroxide and releasing heat.

Jiang Deming stretched out his hand and touched it. He felt that the iron powder was already a bit hot to his hands. He must have been so happy that he couldn't help but smile from ear to ear.

"We made it!"

Now I have made meritorious service again, and I am one step closer to receiving a certificate and a big red flower.

Wang Weidong frowned.

This thing is too crude!

According to the memory of the previous life, the hand warmer patch consists of three parts: raw material layer, gelatin layer, and non-woven bag.

The raw material layer is responsible for generating heat, the gelatin layer can stick the hand warmers to clothes, and the non-woven bag is used to seal the raw material layer.

What they are producing now is just the raw material layer.

Of course, the hand warmers can be worn under clothes, and the gelatin layer is optional.

However, the raw material layer is essential, after all, no one wants to have iron powder all over their body.

What to use instead?

The non-woven fabric layer requires the fabric to be thin so that it can conduct heat more efficiently. Ordinary fabrics are very thick and will not work at all.

Wang Weidong looked at Jiang Deming with a happy face, rolled his eyes, and thought of an idea.

"Jiang Gong, I heard that you are very popular with girls?"

"That's for sure. I'm a top student at Huaqing University. I've been on the battlefield and I look handsome..." Jiang Deming was very confident and was about to describe the past when he was chased by a girl on the university campus.

Wang Weidong interrupted him, "Then you must have a lot of handkerchiefs given by girls, right?"

In this era, there were no handkerchiefs, and girls always carried lightly scented handkerchiefs in their pockets.

Among them, most are light blue and embroidered with butterflies.

Moreover, girls seem to like giving handkerchiefs to others.

"Handkerchiefs? Of course, there are dozens of them in my box!" Jiang Deming raised his face, a little proud.

But when he saw the strange smile hanging on the corner of Wang Weidong's mouth, he immediately realized that something was wrong.

Take another look at the iron powder on the experimental table.

"You, you, you don't want to use my handkerchief to make a non-woven layer!" Jiang Deming stammered.

"Congratulations on guessing it right!"

"No, I won't do it. Although I have forgotten which girl gave those handkerchiefs to me, they are good memories after all."

"Tsk tsk, Jiang Gong, you can't wake up.

Being a scientist means devoting yourself to science, isn’t it just a few handkerchiefs?

Forget it, I'll discuss it with Liu Datou from the third workshop.

He's definitely interested in the project."

"I...I did it!"

What Jiang Deming, a second-hand scientist, cares most about is being said to have no scientific research spirit, and he cannot just watch the honor he has received fly away.

Jiang Deming turned around and ran out before Wang Weidong could react.

Within a few minutes, he ran into the laboratory out of breath and holding a pile of handkerchiefs.

Good guy, these handkerchiefs are colorful and gaudy, there are fifty or sixty of them.

Wang Weidong pouted, this kid still has the potential to be the King of the Sea!

With handkerchiefs instead of non-woven fabrics, Wang Weidong and Jiang Deming came up with the Nuanbao sticker without much effort.

After the bell rang, Wang Weidong went out with a pocket of warm stickers.

I originally wanted to go to Factory Manager Yang first and give some of these warm stickers to Mrs. Yang.

But I didn't expect that General Tie had already opened the door to the office. Director Yang probably left early to do some work.

Wang Weidong had no choice but to ride his bicycle back to the courtyard.

He promised Lou Xiao'e that he would go to Lou's house with her tomorrow.

This young son-in-law had to prepare some gifts for his first visit.

Cigarettes and alcohol are definitely indispensable, and you also have to buy some fruits, meat, and the like.

Meat and fruit are okay, but tobacco and alcohol are not easy to get, and you need special tickets.

Wang Weidong doesn't have any on him, so it seems he needs to go to the pigeon market first to get some tickets.
