September 18, 1649, the twelfth day of the eighth month of the lunar calendar.

In accordance with the prior planning arrangement, Hantang Group issued an order saying that each base, except for the necessary units, can organize the Mid-Autumn Festival Gala, and the required expenses will be directly allocated by the financial company——

Director Li Ziqiang said to Lao Zhang in private: "Isn't this just a left-handed hand-to-right, and there is a superfluous program to come out." ”

Lao Zhang said: "That's fine, otherwise no one would have thought that we would be a big profit, more profitable than the Budai Salt Chemical Industry Zone - however, they are only limited in production capacity now-"

Director Li Ziqiang was happy at that time and said: "Wait, by the end of the year, we will start to use coking and gas production equipment, and next year we will start steelmaking equipment - the current output of electric furnace and soil steelmaking is too low, and then I will see who in the world will compete with my Hongxing Industrial Zone!" ”

Lao Zhang also sighed and said: "Yes, a manual water pressing well technique dares to ask for three thousand taels of silver for the promotion and use of others, which is not counting the supporting equipment, and also asks for other people's eucommia medicinal materials - Mei Lezhi, the manager of the finance company, can't see that people are very dark, usually laughing at Mimi, telling some indecent jokes - three thousand taels of silver, almost more than a thousand taels of rice, right?!" ”

"Who knows the way, but if you want Eucommia to be used as a medicinal herb, you can see the way on the Internet - let their financial company set the price first, if it is high, they are black; If it's low, we'll correct it. People who usually laugh at Mimi have a black heart. ”

Director Li Ziqiang continued: "You say, Lao Zhang, how do we spend the Mid-Autumn Festival?" I'm going to take Tingting over then—"

"I think it's okay to have two days off and one meal."

"Alright, you can send a report to the city of Geranza - I'll go to the foundry again."

Lao Zhang hurriedly said: "I just learned to use the Internet - I still use one finger to type words!" ”

"So you're going to have to practice it - that thing develops the intellect."

Lao Zhang muttered in a low voice, it's not good to call me here, I learned it, and I won't be there in the future.

Hantang Group asked the Zheng family for Eucommia, which was the requirement of the Budai Salt Chemical Industry Zone. It's really not for medicinal purposes, but for the extraction of eucommia gum.

Before crossing, Sun Defa had done relevant tests. He used three methods to extract Eucommia ulmoides gum, respectively using fermentation, toluene extraction and alkali leaching, etc., and after the test results were controlled, he determined that the alkali leaching method had the best effect.

Then, he compared the alkali concentration, extraction temperature and extraction times in the alkali leaching method. ResultsThe results were extracted twice continuously with 10% lye solution at a temperature of 90 °C by alkali leaching method, and the extract was treated with concentrated hydrochloric acid for 2 hours to achieve the purpose of removing the non-glue part of the crude glue, which was the best effect.

In fact, Sun writes in the report that there are two points that we need to pay attention to.

The first point is that in the early stage of alkali leaching, we can also extract its effective medicinal substances first, which does not affect the effect of extracting Eucommia ulmoides gum, and I omitted it in the test.

The second point is that Eucommia gum replaces rubber, which is a false proposition.

First of all, the main component of traditional natural rubber is cis-1.4-polyisoprene, while the main component of eucommia gum is trans-1.4-polyisoprene, which have very different physical properties.

Eucommia ulmoides rubber has rubber and plastic duality, good insulation, water resistance, corrosion resistance, but the disadvantage is that the elasticity is very poor, the heat resistance is poor, and it will be deformed above 50 degrees - it is generally used to manufacture hard rubber products, and if it is used as a material for the production of tires, it is itself "congenitally insufficient".

Of course, with the progress of technology, polymer technology, new technology and synthetic technology have been made of trans rubber to create highly elastic materials, which have the possibility of solving problems such as tire strength, tire life, tire friction and heat release, etc., but the energy consumed here is no less than transforming ordinary bricks into refractory bricks - presumably everyone will understand when you see this metaphor.

Secondly, the yield of eucommia gum is congenitally insufficient. It can produce up to 0.3 tons of rubber per hectare, which is far less than the 1.5 tons per hectare of rubber.

After everyone read the report at that time, Li Ziqiang was still a little disappointed, and said: "I still count on using eucommia rubber to make the tire cushion of my iron wheels - rubber, and it will take at least six years to travel through the past." ”

Sun Defa said: "That's fine, if your car can travel at more than 50 kilometers per hour, then it won't apply-"

Li Ziqiang immediately said, it can't be surpassed, it can't be surpassed.

At that time, Wu Dapeng's heart was dark, at that time, he had a friend who kept saying that Eucommia ulmoides gum must be a state-designated development project, and asked him to raise funds to participate. Wu Dapeng has always treated him as a good friend.

Wu Dapeng said: "So, what is the reason why Eucommia is always mentioned now? Whatever you say, I really don't know much about this-"

Sun Defa thought for a moment and said, "Circle money—and I want to scare those rubber suppliers—"

"Is 10,000 acres of afforestation the same? Can it scare? ”

"It's similar, it's not exactly the same. It's useless, people are not fools. ”

At that time, everyone sighed, and they had to respect the objective law.

The reason why the Hantang Group is now mentioning manual pressurized water wells is because it wants to solve the problem of irrigation of migrant landland in northern Taiwan.

At that time, the Hantang Group really couldn't mobilize the driving force to solve their dry field watering problem, so they had to use the manual water pressure well technology in the backup plan, install it in the field, and let them men, women and children go to manual watering. Eating, where is it so easy to solve? -- If it is popularized in the red embedded agricultural base, first, there is the problem of competing for underground water sources, second, the irrigation area solved by manual pressurized water wells is small, and third, there is still a cost problem.

In fact, in the northern part of Taiwan, especially in the Keelung area, where there is only a seasonal water shortage, not the norm, it is completely possible to use this technique in the short term, and the groundwater level there is high.

In the Keelung Badouzi Coal Mine, when the roadheader excavated to a certain depth, the problem of groundwater came head-on, and the people of the Hantang Group were busy pumping water.

The prime mover has finally returned to its original purpose, Friends of the Miners, pumping hard.

At that time, in the Red Star Foundry, Director Linghu Qinghou went to the Mingren Foundry Workshop and showed the wooden model of the manual water press directly to the Ming People, which was ordered in the Red Star Wood Factory, and the actual ratio was 1:1.

Director Linghu Qinghou was too lazy to explain all the data to them, so he directly showed it to their Mingren and asked them to cast one as it was. If you can't cast it, it's okay, so try it.

Now he and Director Li Ziqiang are busy with the matter of cast iron boilers, and they can't get away for a while, and they will guide these Ming material molders to work in the future, and the level of these ancients is also to cast iron pots and hoes and the like.

But what Director Linghu Qinghou didn't expect was that the cast pipe of the fuselage of the manual water press, the sealing cavity inside the fuselage, the water outlet pipe, and the support point of the pressure rod outside the pipe, these Mingren material molders assigned to the Red Star Foundry didn't use Director Linghu Qinghou's shot, and it was done at once-

At that time, Director Linghu Qinghou watched them skillfully use the method of stacking boxes and continuous casting, and sighed and thought, the sample is also very appropriate to arrange the air outlet during hot casting - you must know that he originally wanted to weld the outlet pipe and support point of the water press, like the world on that side, just make a welding - continuous casting is too troublesome, but they actually got it all at once!

At that time, Director Linghu Qinghou pointed to the two holes up and down the sealing cavity, squinted his eyes and said, "Do you know what these two holes are for?" ”

After thinking for a long time, the Mingren material molder said, "Small, I really don't know what to do——"

"Foolish, huh? These are two one-way valves, one lift and one pressure to form a vacuum here, and the water below will automatically come up. ”

“——”

"Fuck, you don't know fluid mechanics, so what do you know how to make valves?"

“——”

"Let me tell you, now use rubber skin, and later use eucommia gum! Eucommia knows the way, right? ”

"-I've heard of it, this thing is aphrodisiac-"

"Fuck, forget it, you don't know what to do, I'll want ten of these castings first, can you keep it at this level?"

"Even a small amount of hard work can be accomplished! This thing is no more difficult than an iron bell—"

"Fuck, what if it's a hundred?!"

"The little one can do it even if he dies!"

"Okay," said Director Linghu Qinghou as he tried to straighten out his mentality, "everyone's wages are going to rise a little-"

The director of the factory made the fox leave behind the happy Ming people and left alone. These people really didn't use his guidance.

The first pressurized water well was drilled at the Red Star Foundry.

The second construction team of the Ming people dug a well at the designated location. Not to mention that the groundwater level in this time and space is high, and the water is less than four meters away. They built a wall 1.5 meters wide, 2 meters long, and 4 meters deep, and smoothed it with cement on all sides. Two bluestone slabs were found to make a manhole cover, and a hole with a diameter of 40 was chiseled on it to facilitate the lowering of the pressurized water well pipe.

The pressurized water well pipe is also cast by the Ming material molders using the stacked box continuous casting method, which is three meters and a half long, and although the surface is rougher, it can be used completely - this is also unexpected by the director of Linghu Qinghou, who originally planned to use ceramic pipes and seal them with cement.

After the installation, the director of Linghu Qinghou triumphantly poured water diversion water into the pressurized water well. Water diversion can make the silicone rubber pad and the inner wall of the pressurized water well better sealed, making it easier to form a vacuum in the sealing cavity.

Linghu Qinghou pressed up and down a few times, and a stream of water squirted out.

The onlookers exclaimed loudly - Celestials, this water was sucked up by objects made by themselves?! Or is it that the director of Linghu Qinghou is born with divine powers, right?!

Seeing that the water flow had become smaller, Director Linghu Qinghou pressed it a few more times, and the water flow became even bigger!

Youming wanted to step forward and drink a little water, but the director of Linghu Qinghou scolded: "Fuck, can't you see that this water is yellow?!" Drain the water for a while, wash the well and drink it! ”

Then he handed the pressurized well to the onlookers, and the Ming people pressed it repeatedly, and the water kept flowing—the sound of the rushing water could not suppress the laughter of the Ming people.

None of the people from the Hantang Group came to watch, a broken pressure well, who didn't use it when he was a child?

For this purpose, Hantang Group has launched its own inventory, two silicone rubber pads of 1.5 meters multiplied by 1.2 meters, you can get 100 hydraulic presses, and each of them can also have two more sets of rubber pad accessories.

originally thought that it would be enough to solve the dry fields in Keelung, northern Taiwan, but what he didn't expect was that Zheng Bin could go to Keelung in person and carefully observe the operation of the Hantang Group.

When he saw the manual pressure well, he made a request without thinking about it, and Squadron Leader Sun Yu immediately sent him back to Relanza City, and asked Manager Mei Lezhi, I only have the right to use it here. Besides, we also have independent accounting, that is, we bought it from the Red Star Industrial Zone-

Zheng Bin's coming here made Squadron Leader Sun Yu always a little worried, since this turtle came here, those Ming miners, guards, were obviously more afraid of him, which made Squadron Leader Sun Yu unhappy.

Damn, your family has moved here, and you're still afraid of a bird? Servility in the bones!
