Enamel is a very simple technology, which is actually to melt and condense inorganic vitreous materials on the base metal and firmly combine them with the base metal to form a composite material.

Hantang Group has not yet been able to solve the problem of producing and processing composite materials from the inside, and they can only look outward, starting from the peripheral construction.

This is exactly the same as the way they use it against the Ming people - at least so far, they have not done the ideological work of the Ming people, in other words, they have not touched the soul of the Ming people, but they only ask the people to do this and that, and even a qiē is an equivalent exchange in a certain sense - as for whether it is really fair, only God knows - but the Ming people are happy with this kind of exchange at present, so it can only be said that it is fair. Of course, whether the white people in the northern part of Taiwan also think so is not within the scope of the Hantang group's consideration. Because they are war criminals - at least illegally settlers.

The Hantang Group's decision to start the enamel business was by no means because of a hot mind - but a requirement of the Hantang Group at a stage of development.

Take the exhibition of container production and processing materials of Hantang Group as an example.

From wood to ceramics, it's just that they make the most of the resources available on this plane...... As mentioned above, tin is a common metal in Mingda 6, ranking high in gold, silver, iron, copper, lead, tin, zinc and other metals, but due to congenital conditions, this product can not be processed on a large scale, so at first Hantang Group just used it as a coin......

Immediately afterwards, Hantang Group exhibited white iron sheet, that is, galvanized iron sheet.

By the way.

Zinc is also one of the elements whose compounds have been known to humans since ancient times.

The alloy of zinc ore and copper was melted to make brass, which was used by ancient people for a long time. However, the acquisition of elemental zinc is much later than that of copper, iron, tin, and lead.

Hantang Group believes that this is due to the fact that when carbon and zinc ore are co-heated, the temperature quickly rises to more than 1oooc, and the boiling point of metal zinc is 9O6C, so zinc is likely to become a vapor state first, which is lost with smoke and is not easy to be detected by ancient people. In this way, it is only possible to obtain elemental zinc when people have mastered the technical methods of condensing gases.

The world's earliest occurrence and use of zinc was Mingda 6, which was the first area to produce zinc on a large scale from the 1O century to the 11th century, which has archaeological records.

At the end of the Ming Dynasty, Song Yingxing wrote the book "Tiangong Kaiwu", which has the world's earliest record of zinc smelting technology. The production process is very simple, calamine (i.e. sidezinc ore) is filled in a clay pot and sealed, piled into a cone, the gap between the jars is filled with charcoal, and the jars are broken to obtain the extracted metal zinc ingots.

After the exhibition of white iron sheets, large-scale container equipment has the possibility of production and processing.

In daily life, the bucket processed by Hantang Group cannot be underestimated in the process of drought fighting, and it is much more cost-effective than wooden barrels.

However, the application of white iron sheet is too limited, especially in chemical, pharmaceutical, food and other industries. So the enamel business naturally came to the agenda.

In the specific deduction, Hantang Group now, the exhibition of enamel business is conducive to promoting the exhibition of metallurgy, chemical industry, pesticide, medicine, food and other industries, and then it will be a situation where one point exhibition and more blossom and fruit.

Enamel originated from glass to decorate metal. It first appeared in ancient Egypt, followed by Greece. In the 6th century, European inlaid silk enamel, deflorated enamel, embossed enamel, translucent enamel, and painted enamel came out one after another. Enamel began to be developed in China in the 8th century, and the works from the Jingtai period of the Ming Dynasty in the mid-15th century are particularly famous. At the beginning of the 19th century, cast iron enamel was developed in Europe, which laid the foundation for enamel to move from handicrafts to daily necessities.

Of course, due to the backward casting technology at that time, the application of cast iron enamel was subject to many limitations.

Hantang Group is now starting to exhibit it, of course, because it values its industrial use, and as for its daily use, it is only a cascading effect.

Enamel coating on the metal surface can prevent the metal from rusting, so that the metal will not form an oxide layer on the surface when heated, and can resist the erosion of various liquids.

Moreover, under specific conditions, the enamel coating on the metal body shows excellent properties such as high hardness, high temperature resistance, wear resistance and insulation, which makes the enamel products have a wider range of uses. It combines the strength of metal with the gorgeous appearance of enamel and chemical resistance.

As far as the glass-lined low-pressure reactor opened by Hantang Group this time is concerned, it is very cost-effective compared with the stainless steel low-pressure reactor. It can be responsibly said that it is one of the best alternatives to stainless steel products for industrial, civil use.

And it is compared with ordinary thin steel plate enamel products, due to the obvious increase in silicon content, its performance is closer to that of chemical glass, in addition to hydrofluoric acid, fluoride-containing media, strong alkali and concentrated phosphoric acid with a higher temperature than the temperature, it can resist the corrosion of various concentrations of inorganic acids, organic acids, weak alkalis and organic solvents, which is incomparable with other materials.

Even if it is an ordinary thin steel plate enamel product, because it only needs a low-carbon steel plate and is easy to stamp, then its wide range of uses is self-evident.

As for why not stainless steel products, even if they are real products...... Except for the question raised by Secretary Yang Youxing on the Internet, no one has proposed this concept yet.

Secretary Yang Youxing's question has been hanging there alone.

One of the technicians couldn't stand it anymore, so he replied:

"Dear, if we can process stainless steel, it means that we can already process tool steel...... We have made breakthroughs in various technologies, such as the purification of elemental elements, the protective atmosphere of inert gas, the temperature control technology, the power system, the special heat source, the sealed smelting furnace, and ...... Among them, metallographic analysis and monitoring is one of the simplest techniques. ”

“…… Well, when I didn't ask that question...... It seems that in the world over there, enamel-related products have not been raised to such a high position, right? ”

"Dear, it's very simple, just a few words...... When enamel products appear in the world, the exhibition situation of other industries such as chemical industry does not have many requirements for enamel products...... And what about us? I heard that even the large wine cans filled with beer, the partitions of the air heating equipment of thermal power plants, small blast furnaces, and the special pipelines for chemical industry are all enamel products......

“…… What kind of path is this? It's different from the world over there......"

"Dear, this is an exhibition road with the characteristics of Hantang Group...... It's not the old way, it's not the wrong way......"

“…… Thank you for the explanation...... Very comprehensive......"

"Dear, you're welcome, the knowledge of science and engineering students is generally more comprehensive...... For example, Taiwan now has a population of about 140,000, can we now do ideological work through guò and make them become new Ming people who stress governance, democracy, discipline, and morality? ”

"You can't do it now......"

"You see, dear, we all know that internal causes play a major role, but how difficult it is to figure out how internal causes affect external causes...... So, now you know how hard it is to want all kinds of alloy steels......"

“…… Who are you? ”

"Dear, I'm Ma Pan...... The fat horse is me, and I changed the signature myself. ”

"I haven't seen you online in days......"

"yes, I've been busy girls right now...... The cosmetics which I wanted were very busy. ”

In the plan of the Hantang Group, the bag enamel factory and the bag glass factory are connected in parallel, and they share the supply of gas, so now the town of Budai has to increase the intensity of gas production, and the special valves they carry for gas production and transportation are currently used there.

This made Director Li Ziqiang greedy all the time. If his small blast furnace can also use gas, then the quality of smelting will not be improved by a grade.

Lao Zhang persuaded Director Li Ziqiang and said: "Chairman Li, we don't have to be envious, wait until we finish this wave of tasks...... I also have time to process the gas production equipment myself, I have read the relevant drawings on the Internet, and the equipment is quite simple...... As for the special valve or something...... We can process it by ourselves, and we don't need CNC control. ”

"Lao Zhang, have you learned to surf the Internet? That's a good thing......"

"No, can you let me pass? It's not difficult to learn it...... That's it, it's just that the typing is slow, and the pronunciation is not allowed......"

"Lao Zhang, don't be in a hurry, take your time, I'm not in a hurry......"

The third thing that Director Li Ziqiang wants to solve is the price problem of industrial supplies...... This is a question that needs to be dealt with directly with Manager Merge, so he can't afford not to think about it carefully.

During this period of time, the products of the Red Star Industrial Zone have been supported by the Zheng family, and they can always be maintained at a high price.

The Zheng family increased the number of grenades they bought, which made the number of cast iron shells needed for the production of grenades in the Red Star Foundry also increased accordingly, and at the same time, since the sale of grenades was linked to the supply of pig iron, this also meant that the Red Star Foundry sold a cast iron shell, not only to earn back two or three pig iron of the same weight, but also to sell it to others at a high price...... The profiteering nature of the arms trade has been fully demonstrated.

At the same time, the emergence of pressure wells has been recognized by the majority of Ming people, not to mention the Zheng family, just to say that the Ming people in Taiwan have fully accepted this extremely advanced equipment.

In the Chichi agricultural base area, the first to accept it were Zhangjia Distillery and Liujia Distillery. When they saw Hantang Group using this technology during the drought fight, they circled the manual pressure well many times, tried it themselves, and then decided to buy it without even thinking about it......

At that time, Hongxing Industrial Zone did not expect that the people would generate demand so quickly, and it was not a big customer like the Zheng family and the Pan family, but two local wineries...... It is precisely because they are local customers...... At that time, the pricing was lower, and the political intention was greater than the economic purpose...... In this way, the related products of the Red Star Industrial Zone can be said to have quickly occupied the local market...... A considerable number of the blacksmiths who had been let go long ago could only come back on their own initiative and continue to work in the Red Star Industrial Zone...... The rest of the blacksmiths had to make a living by doing things like tinkering.

In the eyes of the Hantang Group, this Hongxing Industrial Zone, which is still in its embryonic state, has just revealed a sharp corner, and it has already shown its power.
