With the publication of the advertisement in the "Special Zone News", it immediately aroused a warm response, and it was only a matter of time before Mao Geng became a great Song Fu with an unprecedented degree in the past year or so. What does Mao Geng rely on? Relying on exclusive new technology, this technology is Mao Geng's cornucopia. If you can buy Mao's technology, you will have the key to get rich quickly.

The temporary office space for technology transfer is located in the community where Su Zhiyan lives, and the model house is directly occupied for the office. During the day, it is an office building for technology transfer, and at night it is still used as a model building, but the customer groups received during the day and night are not the same.

Some businesses based in the Special Economic Zone have been the first to get there, but they have spent money to buy a number of technical introduction materials, and they can only buy a technical introduction with money, and irrelevant personnel will certainly not spend this unjust money. The reason why you want to collect money is because of the intention of saving if you are not sincere.

Five days later, we will talk about technology transfer specifically, according to Wu Yixin, this is to ensure fairness, after all, technology transfer cannot be carried out on a first-come, first-served basis.

Despite the cost of money, and the usual amount of money for a few pages, hundreds of copies were bought in one morning.

At this moment, Mao Geng accompanied Zhao Lu on a ship under construction, and commented on the ship that was almost completed.

The newly built ship is the iron ship in Zhao Luan's mouth, but this is suspected of stealing the concept, because the main body of this iron ship is still a wooden boat, but above the waterline, it will be covered with a layer of iron sheet.

The ship started construction three months ago, except for the improvement of the ship, which adopted the shape of the outward, and the rest was built according to the traditional ships of the Great Song Dynasty, and the key change was on the surface of the ship.

This era has not yet entered the era of artillery, and if there is artillery, it will only be available in the Great Song Dynasty for the time being, and for wooden ships, the most feared is the enemy's fire attack. Yu Yunwen commanded the Great Song Dynasty naval army to defeat the Jin soldiers and naval forces on the Yangtze River, which used iron artillery, a fire attack weapon, and the trebuchet threw iron artillery, and the explosive destructive power was negligible, but the fire attack power of the iron artillery was enough to burn the warship, and the Jin soldiers and naval army were defeated.

Therefore, Mao Geng in the consideration of how to prevent fire attack, can be described as painstaking, obviously, a layer of iron is not enough to prevent fire, this era has been a large number of use of fire oil as a fire attack weapon - fire oil is oil, how can a thin layer of iron sheet withstand the fire ablation of fire oil, needless to say, it will soon be burned through, and then it will ignite the wood below, so a simple layer of iron sheet is unable to resist fire attack.

To this end, Mao Geng designed a layer of barbed wire cement fireproof layer on the outside of the wooden hull, the barbed wire was nailed to the hull, and then brushed with a layer of three-centimeter fine sand concrete mortar, so that it not only has the tough impact resistance advantage of the wooden ship, but also has the fireproof effect of the cement ship, and then pasted a layer of iron sheet on it, hehe, and the armor effect of the iron ship. It's really the most powerful warship of this era.

The cement has almost hardened, and today it is finally possible to lay the first sheet of iron.

Walking up to the deck, I saw that the concrete deck was drawn with long lattices one by one, and the iron sheets would be nailed to the deck according to these lattices. The corners of the lattice and the midpoint of each side have exposed wooden posts, which are used to nail the iron sheet.

A worker first lays the next layer of asphalt in two adjacent squares, which is used as a buffer layer, and then two workers who lay iron sheets come forward, one holding a galvanized iron sheet, the iron sheet is long, forty centimeters, and one meter wide, which is rolled out by the first generation of rolling mills. The four sides of the iron sheet are stamped and processed, and four narrow edges of 1.5 centimeters are washed down, these four narrow edges are five millimeters lower than the entire iron sheet plane, there are holes in the side strips, the narrow sides of the two iron strips are put together, and after the erection is completed, a three-millimeter-thick iron strip is pressed on the narrow edge of the concave in the middle of the two plates, and then nails are nailed through the pre-made holes, and the two buckled iron sheets are fixed on the deck.

After nailing the four boards, Mao Geng asked Zhao Lian to stand up and try it, the two stepped on the iron deck, they felt very steady, and then felt that there was still some elasticity under their feet, Zhao Lian was very satisfied, and said happily:

"Not bad! I like this tin deck very much, and I guess our Great Song sailors will not be in a big deal if they fall on it. ”

Depend on! That's how you understand it! Mao Geng said in his heart, I am going to deal with the solid bullets that the enemy will fight in the future, okay!

In short, Zhao Lian is satisfied, today's steel resources are limited, Zhao Lian wants to build an iron ship, this is the iron ship that Mao Geng built for Zhao Luan, anyway, it is wrapped in a layer of iron sheet, and it is barely reasonable to call it an iron ship.

In Mao Geng's mind, this kind of iron-clad ship is weak, but there is a process for every qiē, and it can only be done step by step. According to Mao Geng's plan, such an iron-clad warship was built first, and then the dome armor ship was built on the basis of the wooden hull, and finally the ironclad ship was built. Mao Geng will not choose to make a big move, because the situation is not urgent to that extent, if you really want to build an ironclad ship, you need to have a reserve process from steel and construction technology.

After wrapping the iron sheet and outfitting, the ship is really completed, and I am afraid it will have to wait for a few years. After the year, after the year, there is no need to rush for time.

After getting off the boat, Mao Geng and Zhao Lu got on another boat, which was different from the iron boat, which was designed by Mao Geng according to the nineteenth-century flying scissor sailing ship, using a hollow boat, with a length-to-width ratio of six to one, which looked slender and slender, and the superstructure of the ship would be simplified to the extreme. In view of the fact that the hull is far less round and full than the traditional sea ships of the Great Song Dynasty, Zhao Lian does not like the style of this boat very much, but I heard Mao Geng say that this kind of boat will run very fast, although Zhao Lian has some doubts, but Mao Geng has always been magical, he said that he runs fast, maybe it really won't run slow.

After a look around the ship, deck construction has just begun, and there is still a lot of work left. Due to the focus on ensuring the construction of the iron boat, the attention paid to this flying clipper ship is not enough, even if it is hurried and slow, the completion date will be at least after the Lantern Festival.

Shipbuilding is like this, and there is no hurry, maybe after this ship is launched, shipbuilding will be faster in the future.

In fact, there is no need for Mao Geng to worry about shipbuilding, there is Zhao Lu staring, Jiang Ang is also very good at doing things, Mao Geng only occasionally asks, like today this is the first time to nail the iron sheet, Mao Geng is not at ease, specially come to see, most of the time, Mao Geng basically only pays a little attention to the progress of shipbuilding, controls it at the technical node, and at other times, it is left to Zhao Lu and Jiang Ang to tinker.

Leaving the shipyard, Mao Geng came to the medical laboratory.

This laboratory has been open for a while, and Imperial Physician Yu and Huang Zaixin are in charge of this laboratory. Imperial Doctor Yu is the head doctor of the SAR Hospital, and he doesn't spend much time in this laboratory, so most of the time Huang Zaixin works in the laboratory with two assistants.

Today, Mao Geng asked someone to send a simple microscope, Mao Geng just came to see, and by the way, he taught Huang Zaixin how to use this baby microscope.

Huang Zaixin really regarded the microscope as a treasure, and after sending it over today, he offered this microscope as a god, and he didn't even dare to move a finger on it.

Mao Geng smiled, and then began to teach Huang Zaixin how to use the microscope.

When Huang Zaixin saw a small ant in the microscope enlarged into a big ant, his surprise was self-evident, and then Mao Geng used a piece of glass to drip a drop of water to let Huang Zaixin see the movement of bacteria in the water.

"See? The things that move in the water. ”

After a while, Huang Zaixin removed his eyes from the microscope and replied:

"Well, there's something moving, and there's actually such a moving thing in a drop of water, what are they?"

"Oh, that's bacteria, and when you see more of it, you'll slowly understand."

"So, what's the use of this microscope? What are the benefits of seeing these small --- and small bacteria for our medicine? ”

Mao Geng didn't know how to tell Huang Zaixin for a while, and when he saw the experimental mice in the cage over there, he smiled and said:

"Huang Yaoshi, haven't you used rats to do drug tests before! Now it seems that he is already familiar with the road! With a microscope, this is probably the case, and the later it is, the more handy it becomes. ”

"I hope so!" , Huang Zai confidently said that the pharmacology of using mice to make some drugs is really quite rewarding, and I hope that after using this microscope, it can also be the same.

Mao Geng saw Huang Zaixin nodding, so he asked with a smile:

"After Huang Yaoshi came here, he should have collected a lot of various medicinal materials, I don't know what kind of good medicinal materials he has collected recently?"

"Well, don't hide it, I received a good medicine today, I didn't expect that there is comfrey here, and this medicine looks really good." , the pharmacist encountered the best medicinal materials, of course, he was in a good mood, and when he saw Huang Zaixin's joyful appearance, it was conceivable that he had found a treasure.

But Mao Geng suddenly remembered something in his mind, and immediately asked:

"You mean comfrey? It's also called shellac and red gum, right? ”

"Not bad! Precisely. I can't imagine that Mao Te also has a dabbling in medicinal materials, which is really admirable! ”

Admirable fart! This is just a middle school classmate in his previous life who later came to a certain mountainous county to become the deputy county magistrate in charge of agriculture, and spent all day and night to show off the characteristic economy of the mountainous area, and when they were together, they couldn't help but brag about what special products he had under his rule. His brother bragged about the successful introduction of Taiwanese jujube trees to produce green glue and ecological glue, so Mao Geng knew that there is a kind of insect in the world that spits out natural gum - lac worm!

Lac insects survive by absorbing the sap of parasitic trees, and secrete purple natural resin, also known as lac, red gum, and comfrey. Shellac is not only a traditional Chinese medicine, the history of traditional Chinese medicine can be traced back to the Han Dynasty, and it is also a strong adhesive resin. Shellac resin has strong adhesion, toughness, good luster, both thermoplastic and thermosetting, oil resistance, acid resistance, non-toxicity and irritation to people, can be used as varnish, polishing agent, adhesive, insulating material and molding material, etc., national defense, electrical, coating, rubber, plastic, medicine, tanning, papermaking, printing, food industry will use it - hehe, almost no industrial sector does not use it.

Lac insects also produce wax - shellac wax, also known as shellac wax, is a yellow hard natural wax with high hardness and good luster, which can be used as a polish, such as adding to shoe polish. In addition, shellac pigment is a bright red non-toxic powder that can be used as a green edible red pigment.

Don't say it, during this time, Mao Geng's mind is either this glue or that glue, cod liver oil to use gelatin, buttons to use gelatin and vegetable glue, tires to use the highest requirements for composite glue, Mao Geng has always hoped to find a good glue, after adding it, can further improve the performance of composite glue.

Regarding vegetable gum, Mao Geng has successfully extracted konjac gum before, but the viscosity of konjac gum is not strong enough. Therefore, Mao Geng also plans to harvest Tian Jing and prepare to extract Tian Jing gum, but so far he has not had time to try it.

Now it's good! This natural shellac is a good thing, it seems that it can be used to make bullets, and I can't imagine that Taiwan has it!
