Chapter 574 Our chairman is the most insidious!

Lu Guangming looked at Li Weidong with a bewildered expression, waiting for him to reveal the answer.

Li Weidong explained: According to the method of oxygen production, there are many kinds of oxygen generators. For example, industrial oxygen production, there are mainly four methods, separation of liquid air, membrane separation technology, molecular sieve oxygen production, and electrolysis. oxygen method.

Among them, only the molecular sieve oxygen generator is most suitable for use in household oxygen generators, that is to say, using the pressure swing adsorption technology you mentioned, the gas is separated and oxygen is extracted from the air.

Yes, as far as the current level of technology is concerned, this is a household oxygen concentrator or a small medical oxygen concentrator, and only this technology can be used. Lu Guangming nodded.

The demand for oxygen in the industry is very large, such as metallurgy, chemical industry, petroleum, national defense and other industrial production fields, all need to use oxygen, so as early as the beginning of the twentieth century, human beings will start industrial oxygen production, and Various means were investigated.

Among them, the electrolytic oxygen production method is the easiest to understand, which is to electrolyze water into oxygen and hydrogen. This method consumes a lot of electricity, and the amount of oxygen produced is not high.

Moreover, the mixture of hydrogen and oxygen is more prone to explosion, which is very unsafe, so in actual production, enterprises will not use this method to produce oxygen.

The method of separating liquid air is to pressurize the air under low temperature conditions, so that the air changes from a gaseous state to a liquid state, and then evaporates.

The main components in the air are nitrogen and oxygen, of which the boiling point of liquid nitrogen is minus 196 degrees, and the boiling point of liquid oxygen is minus 183 degrees, and the boiling point of liquid oxygen is higher, so nitrogen will evaporate from the liquid air first, and the remaining is liquid oxygen.

Of course, the air should be purified before this to remove impurities such as dust, moisture, carbon dioxide, and hydrocarbons.

Membrane separation technology is to allow air to pass through a membrane with oxygen-enriched function, that is, oxygen-enriched membrane, so that air with a higher content can be obtained.

However, there is no way to obtain high-purity oxygen in this method, and the combustion efficiency is mainly improved in industry.

Molecular sieve oxygen generators use physical methods, using pressure swing adsorption technology, and using the characteristics of nitrogen molecules larger than oxygen molecules to absorb oxygen in the air.

Of these four main technologies, the first two must only be used for industrial oxygen production, one requires electrolysis of water, and the other requires air liquefaction, which is destined to be unsuitable for home or small medical oxygen generators.

Therefore, home oxygen concentrators or small medical oxygen concentrators can only use the latter two methods.

Membrane separation technology is very suitable for small oxygen generators. The key to this technology is material. As long as the material of that layer of oxygen-rich membrane passes the test, the rest is nothing more than an air extraction system.

Therefore, at the beginning of the 21st century, household oxygen-enriched membrane oxygen generators have been built, which were first produced in Japan, and Japan also used oxygen-enriched membranes in the home appliance industry to produce oxygen-enriched membrane air conditioners. product.

A few years later, there are also domestic companies that have produced oxygen-enriched membrane oxygen generators, but the most critical oxygen-enriched membranes in them need to be imported, which means that nuclear components are completely in the hands of foreign countries.

Moreover, the imported oxygen-enriched membrane also greatly increased the cost of the oxygen generator. Therefore, the price of the oxygen-enriched membrane oxygen generator at that time was not close to the people, and it was expensive to sell.

Another point is that the oxygen production effect of the oxygen-enriched membrane oxygen generator is not very good. The oxygen content in the air is about 21%, and the oxygen-enriched membrane oxygen generator can only increase this ratio to 30%, which is much worse than other sample preparation methods.

30% oxygen content is not very effective. This oxygen generator can only play a general health care effect, and its medical effect is not large.

Few people will spend a lot of money to buy an oxygen generator with an unsatisfactory oxygen production effect, so when this oxygen-enriched membrane oxygen generator was just launched, there were hardly many sales.

It was not until later that progress was made in oxygen-enriched membrane technology in China, and the price of oxygen-enriched membrane oxygen generators dropped sharply, which was gradually accepted by the market.

The industrial production method of molecular sieve oxygen generator is also very complicated.

The air needs to be purified, then evacuated, and an adsorption tower is used.

However, if it is not for industrial production, the quality requirements for oxygen are not so high, and a vacuum pump can solve the process problem.

If Li Weidong develops an oxygen-enriched membrane oxygen generator, then he needs to develop an oxygen-enriched membrane, which is actually a technical field of molecular materials and has nothing to do with medical devices.

The molecular sieve oxygen generator is different, this is a serious medical device research and development, and the molecular sieve oxygen generator is developed, the puppy can get a pressure swing adsorption technology anyway.

Molecular sieve oxygen generators are indeed in line with the development trend of oxygen generators. The most widely used type of oxygen generator in later generations, which is not much different from luggage, is the molecular sieve oxygen generator with a water bottle on it.

...

Just listen to Li Weidong and say: What I just said are all methods of industrial production of oxygen, mainly for large-scale oxygen production. But for household use, large-scale oxygen production is not required.

If it is not large-scale oxygen production, then in addition to what I just said, there is a simpler way to get oxygen, and that is chemical reaction!

Using chemical reactions to obtain oxygen is the content of junior high school chemistry courses, and it is also a compulsory subject in the senior high school entrance examination. No one will find this method unfamiliar.

Hearing the chemical reaction to produce oxygen, Lu Guangming frowned and asked, Chairman, do you mean to use chemical preparations to produce oxygen?

Li Weidong nodded: Yes, we can first make an oxygen generator that uses chemical preparations to produce oxygen. This thing has a very simple structure and basically does not require research and development. We use this simple oxygen generator to make some money first, and then Use this money to invest in the research and development of molecular sieve oxygen generators.

Hearing this idea, Lu Guangming showed a disdainful expression. He seemed to despise this kind of non-technical thing.

Then Lu Guangming said: Chairman, with all due respect, the product you mentioned already exists on the market, and the sales are quite good, and many people buy it.

I have seen this kind of product, it is two connected water tanks, one side is adding oxygen generator, and the other is adding catalyst, then cover the lid, and attach a straw, waiting for the oxygen generator inside to have a chemical reaction with the water, and then produce out oxygen.

You're talking about Oxygen, right? Li Weidong asked with a smile.

So you know! Lu Guangming said in surprise.

Li Weidong nodded: Of course I know, this Oxygen Stand is earlier than our company was established. When we started selling massage seats, others had sold oxygen concentrators for several years.

...

Oxygen was founded in 1990 when they introduced a portable oxygen generator that used the principle of chemical reactions.

The so-called oxygen generator is actually a plastic water tank. The water tank is divided into two parts, and the bottom is connected together.

When using more, one side of the oxygen generator is added, and the other side is added with a catalyst, and the two are in contact at the bottom of the water tank, so that the oxygen generator reacts with the water, and oxygen is produced.

The so-called oxygen generator is actually sodium percarbonate. When this kind of thing encounters water, it will undergo a chemical reaction to generate sodium carbonate and hydrogen peroxide. Because the hydrogen peroxide is unstable, it will decompose into water and oxygen.

The catalyst is manganese dioxide, which can speed up the reaction process and obtain a large amount of oxygen quickly.

Sodium percarbonate is simple and convenient to produce oxygen, and can supply a large amount of oxygen in a short time, which is very suitable for those areas with low industrial level.

When China's industry was still relatively backward, the hospitals in Beijing alone used 400 tons of sodium percarbonate a year for oxygen production.

In the years when the international situation was relatively tense, many underground civil air defense projects were built in China. At that time, these projects had to store carbon peroxide for oxygen production in emergencies. Therefore, carbon peroxide once became a very important strategic material.

Since the industrial oxygen production method has gradually become popular, sodium peroxide oxygen production has been gradually eliminated, mainly because the cost of this method is relatively high, and large-scale industrial oxygen production is not cost-effective.

Because sodium peroxide reacts with water, it can generate hydrogen peroxide, so this compound is also used as a bleaching agent and an oxidant in the industry, such as chemical industry, papermaking, textile, printing and dyeing, food, washing and other industries.

In contrast, directly using it to make oxygen is a waste. The hydrogen peroxide produced by one kilogram of sodium peroxide can be more valuable than oxygen and water.

Therefore, in the early 1990s, after Oxygen launched the oxygen generator, it was tepid in the first few years, because the price of oxygen generator was too high.

An oxygen generator, including a packet of sodium percarbonate and a packet of manganese dioxide, can only be used for about fifteen minutes, and the price of this oxygen generator will be sold for five or six dollars, in the 1990s. In terms of the income level of the Chinese people in the early days, how could they afford it!

And those who can afford an oxygen concentrator are the kind of people who don't need to spend money in hospital. If they need oxygen, a phone call, and the hospital can send an oxygen tank to their home. They don't need this kind of thing.

It was not until the mid-1990s that sales of Oxylite began to increase with the gradual increase in national income.

In addition, it was the hottest era of health care products at that time, and various exaggerated health care product advertisements emerged one after another, so it is easy to sell the product if it is properly promoted.

Oxygen entered a glorious period after the rise of TV shopping.

In the late 1990s, domestic TV shopping developed rapidly. Even the fourth- and fifth-tier cities and some county towns already had TV shopping channels. Through this channel, Oxygen has entered thousands of households.

...

I just heard Lu Guangming say: Chairman, as far as I know, there are quite a few advertisements about Oxylite on TV, and they are all TV shopping shows. They have already made this product, if we make the same product now , is it too late?

It's not too late. Li Weidong shook his head with a smile, and continued; You must know that although their products are earlier, we have three major advantages.

First of all, we have the hospital channel, starting from the sale of massage chairs, we have been operating the hospital channel for so many years, our representatives are very familiar with the hospital, and we also have cooperative relations with many hospitals, which other companies do not have. of.

Secondly, our brand awareness is relatively high. There are too many health care products that have emerged in recent years. There are all kinds of products, and most of them are brands that have never been heard of.

The puppy brand is also a well-known brand in China. If the same product has a brand bonus, it will be easier to gain the trust of consumers.

Third, we are a professional medical device manufacturer. It is very important that we produce regular medical devices, not health care devices.

Because we produce medical devices, we can advertise according to medical devices when promoting, but other companies cannot.

If they do not have the qualification to produce medical devices, or the products have not obtained the certification of medical devices, but they publish medical device advertisements without authorization, it is a violation of regulations. At that time, we can report to the food and drug supervision department, and we will definitely make a decision!

Lu Guangming is also an old fritter in the mall. He heard Li Weidong's last sentence and instantly grasped the point.

Chairman, are you saying that Oxygen does not have the production qualifications for medical devices? Lu Guangming asked immediately.

Li Weidong did not give a clear answer, but said: How many of these domestic companies that produce health care devices have medical device production qualifications? Medical device production qualifications are not so easy to obtain.

Even if they have the production qualification of medical devices, are their products medical devices? Is there any certification from the relevant state departments?

If they don't have any of these, but advertise the product as a medical device, it is to publish medical device advertisements without approval, which is to deceive and mislead consumers.

At this time, the media will blow the wind again and properly publicize the harm of counterfeit medical devices. It is not certain who is Li Kui and who is Li Gui at that time!

False propaganda was the norm in the health care product industry at that time. How could there be any health product that did not false propaganda? You can't sell it without false advertising!

Many oral health products are promoting the efficacy of curing diseases, telling consumers overtly and secretly that I am a medicine.

The same is true of health care devices, all kinds of express hints, exhaustive ways to label medical devices on themselves.

This is mainly caused by the irregularity of the domestic health care product market. It is an unspoken rule of the industry. Everyone does this. Although it is a violation of the rules, it is basically a state where the people do not raise the bar.

But if someone really reported it, then the law enforcement department would naturally have to do something.

Oxygen is a member of the industry, and of course it is doing this for many years. Until 2006, the State Food and Drug Administration began to publish the Summary of Illegal Medical Device Advertisements, and Oxygen became famous in the newspapers.

The production qualification of medical devices is not easy to obtain, and the state's management in this area is still relatively strict. Not just any cat or dog can obtain a medical device production license.

The production of medical devices also requires the qualification approval of the relevant departments. Only when the competent department determines that you are producing a medical device can it be a real medical device.

None of this is a problem for Li Weidong.

Puppy Health originally chose to acquire the Jinzhou Medical Device Factory instead of building a new factory. The main reason is that the Jinzhou Medical Device Factory has a complete medical device production qualification, which can easily pass the medical device production qualification approval.

Those companies that produce health care equipment may not have such good resources.

Even if everyone sells the same product, mine is a medical device and yours is a health device, which one will consumers trust more?

And I can freely advertise my product as a medical device, but you can't. If you advertise a health care device as a medical device, go to the Food and Drug Administration to make an announcement!

So when Li Weidong mentioned Li Kui and Li Gui, Lu Guangming instantly understood Li Weidong's intention.

Lu Guangming thought in his heart: If you want to talk about insidiousness, you still have to look at our chairman! The product is still in words, and it starts to calculate competitors!
