Siheyuan: Start with a Truck Driver

Chapter 160 Must Support!

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

Anyway, the hand warmers were produced by the island nation in the 70s, and Wang Weidong felt no guilt about pirating them.

Moreover, the cost of hand warmers is low, and the heating components are iron powder, activated carbon, non-metallic mineral powder and salt, which are not considered as 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 promoted quickly and occupy the market.

I originally thought of a warm water bag, but now it seems that this warm treasure sticker seems to be more suitable.

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

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

How smart is this truck driver!
In front of Wang Weidong, Jiang Deming felt that he was a primary school student.

Man, do what you say!

The two discussed for a while, listed a list of materials, and went to Director Yang's office together.

Director Yang frowned looking at the list of materials, how much money would it cost for so many materials!

But I heard that the two were making low-cost hand warmers, and without a word, they issued a letter of introduction for purchasing materials.

After all, he has seen the effect of the hand warmer with his own eyes.

Ever since my wife used the hand warmer, that old cold leg has never happened again, and I climbed the third floor in one breath without panting.

God!

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

Factory Manager Yang was still thinking about how to ask Wang Weidong to make more hand warmers, but this kid actually tinkered with hand warmers again.

Moreover, the cost of the hand warmer is still very low, and it can be mass-produced.

Must support!

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

The saleswoman who was knitting a sweater saw the letter of introduction, looked them up and down again, asked them to show their work permits, and checked and interrogated them in detail.

If it weren't for the high cost of calling, she might have called the rolling mill to check.

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

The conscientious and responsible spirit made Wang Weidong sigh that people are so vigilant in this era.

After 10 minutes, the salesperson aunt took out the iron powder and activated carbon.

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

Vermiculite is a natural, inorganic, non-toxic mineral that expands under high temperature.

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

Since ancient times, everything can be traditional Chinese medicine.

Take the excrement of animals as an example, the droppings of flying squirrels are Wulingzhi, the droppings of bats are Yemingsha, the droppings of wild rabbits are Mochiyuesha, the droppings of sparrows are Bailixiang, the droppings of pigeons are Zuolongpan, and the droppings of horses. It's Baimatong.

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

There is a shortage of supplies these days. When researchers lack experimental materials, the first thing they think of is the traditional Chinese medicine shop.

In less than two hours, the two bought 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 crank handle in his waist.

The crank was always poking him in the back.

It hurts to poke.

Jiang Deming grinned all the way, his face full of pain.

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

After collecting all the materials, start summoning the dragon.

Pooh!
It is to make hand warmers.

The production process of the hand warmer stickers is simple. Under the guidance of Wang Weidong, the second-hand scientist Jiang Deming made them without any effort.

After the iron powder on the test bench is exposed to humid air, under the action of table salt, a chemical reaction occurs rapidly to form iron hydroxide and release heat.

Jiang Deming stretched out his hand to touch it, and felt that the iron powder was already a little hot, so he was so happy from ear to ear.

"We made it!"

Now he has done meritorious service again, and he is one step closer to winning a certificate and hanging a big red flower.

Wang Weidong frowned.

This thing is too crude!

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

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

All they've produced now are the raw layers.

Of course, the hand warmer can be used in clothes, and the gelatin layer is optional.

But the raw material layer is essential, after all, no one wants iron powder to cover the whole 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, which is impossible at all.

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

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

"That's for sure. I'm a high-achieving student at Huaqing University. I've even been on the battlefield. I'm still handsome." Jiang Deming was very confident, ready to tell the story of being chased by girls on the university campus.

Wang Weidong interrupted him, "Then you must have handkerchiefs from many girls there, right?"

In this day and age, there are no handkerchiefs, and girls always carry handkerchiefs with a faint fragrance in their pockets.

Most of them are light blue and embroidered with butterflies.

Moreover, girls seem to like to give handkerchiefs to others.

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

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

Take another look at the iron powder on the test bench.

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

"Congratulations on your guess!"

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

"Tsk tsk, Jiang Gong, you're not good enough.

To be a scientist requires the spirit of dedication to science, isn't it just a few handkerchiefs!
Forget it, I'll discuss it with Big Head Liu from the third workshop.

He was definitely interested in the project. "

"I did it!"

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

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

Within a few minutes, he ran into the laboratory panting with a bunch of handkerchiefs in his arms.

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

Seeing that Wang Weidong curled his lips, 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 fiddled with warm treasure stickers without much effort.

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

Originally, I wanted to go to Director Yang first, and distribute some of the warm treasure stickers to Mrs. Yang.

But I didn't expect that the door of the office was already guarded by General Tie, and Factory Director Yang probably left early to 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 came to the door for the first time, so he had to prepare some gifts.

Tobacco and alcohol are definitely indispensable, and some fruits, meat, etc. must be bought.

Meat and fruit are easy to talk about, but tobacco and alcohol are not easy to deal with, and special coupons are required.

Wang Weidong didn't have it on him. It seemed that he had to go to the pigeon market first to get some tickets.
