Chapter 574 Our chairman is the most insidious!
Lu Guangming looked at Li Weidong in confusion, 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 mainly consists of four methods: liquid air separation method, membrane separation technology, molecular sieve oxygen production, and electrolytic production. Oxygen method.
Among them, only molecular sieve oxygen generators are most suitable for use in household oxygen generators, that is to say, using the pressure swing adsorption technology you mentioned to separate gases and extract oxygen from the air.
Yes, as far as the current technical level is concerned, this is a household oxygen generator or a small medical oxygen generator, and this technology can only be used. Lu Guangming nodded.
There is a great demand for oxygen in industry, 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 20th century, human beings will start industrial oxygen production, and Various means were studied.
Among them, the electrolytic oxygen production method is the easiest to understand, that is, the electrolysis of water into oxygen and hydrogen. This method consumes a lot of power and the amount of oxygen produced is not high.
Moreover, the mixture of hydrogen and oxygen is relatively 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 gaseous state to liquid state, and then evaporates.
The main components in the air are nitrogen and oxygen. The boiling point of liquid nitrogen is minus 196 degrees, while the boiling point of liquid oxygen is minus 183 degrees. 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, before this, the air should be purified to remove impurities such as dust, moisture, carbon dioxide, and hydrocarbons.
Membrane separation technology is to let air pass through a membrane with oxygen-enriching function, that is, an oxygen-enriched membrane, so that air with a higher content can be obtained.
However, this method has no way to obtain high-purity oxygen, and in the industry, it mainly improves the combustion efficiency by a small margin.
Molecular sieve oxygen concentrators use physical methods, using pressure swing adsorption technology, and using the characteristics that nitrogen molecules are larger than oxygen molecules to absorb oxygen in the air.
Of the 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, household oxygen generators or small medical oxygen generators can only use the latter two methods.
Membrane separation technology is very suitable for small oxygen generators. The key to this technology is the material aspect. As long as the material of the oxygen-enriched membrane is qualified, the rest is nothing more than a pumping system.
So at the beginning of the 21st century, household oxygen-enriched membrane oxygen concentrators had already been produced, which were first produced in Japan, and Japan also used oxygen-enriched membranes in the home appliance industry to produce such as oxygen-enriched membrane air conditioners. product.
A few years later, domestic companies also produced oxygen-enriched membrane oxygen generators, but the most critical oxygen-enriched membrane inside needs 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 extremely 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, but the oxygen-enriched membrane oxygen generator can only increase this ratio to 30, which is much worse than other sample preparation methods.
The effect of the oxygen content of 30 is not great. This kind of oxygen generator can only play a general health care effect, and the medical effect is not great.
Few people will spend a lot of money to buy an oxygen concentrator with a less than ideal oxygen production effect, so when this oxygen-enriched membrane oxygen concentrator was first launched, there were hardly many sales.
It was not until later that China made progress in oxygen-enriched membrane technology 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 vacuumed, and an adsorption tower is used.
But if it is not 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 actually belongs to the technical field of molecular materials and has nothing to do with medical devices.
The molecular sieve oxygen generator is different. This is a serious research and development of medical devices, and the research and development of molecular sieve oxygen generators can at least obtain a pressure swing adsorption technology for the health of the puppy.
Molecular sieve oxygen generators are indeed in line with the development trend of oxygen generators. The most widely used oxygen concentrator in later generations, which is not much different from luggage, has a bottle with water on it, which is the molecular sieve oxygen concentrator.
I only heard Li Weidong continue to say; What I just said is the method of industrial production of oxygen, which is mainly used for large-scale oxygen production. But for home use, large-scale oxygen production is not required.
If it is not a large-scale oxygen production, then in addition to what I just said, there is an easier way to get oxygen, that is chemical reaction!
The use of chemical reactions to obtain oxygen is the content of junior high school chemistry classes, and it is also a compulsory subject in the senior high school entrance examination. No one will feel unfamiliar with this method.
Hearing the chemical reaction to produce oxygen, Lu Guangming frowned and asked, Chairman, you mean to use chemical preparations to produce oxygen?
Li Weidong nodded: Yes, we can first make an oxygen concentrator that uses chemical preparations to produce oxygen. Use this money to invest in the research and development of molecular sieve oxygen generators.
Hearing this idea, Lu Guangming showed a disdainful expression, as if he looked down on such untechnical things.
Then Lu Guangming said: Chairman, with all due respect, the product you mentioned already exists on the market, and the sales volume is quite good, and many people buy it.
I have seen this kind of product, it is two sinks connected together, one side is filled with oxygen generator, the other side is added with catalyst, then the lid is closed, and the straw is inserted, waiting for the chemical reaction between the oxygen generator inside and the water, and then produce Oxygen out.
You're talking about Xylide, right? Li Weidong asked with a smile.
So you know! Lu Guangming said in surprise.
Li Weidong nodded: Of course I know. This oxygen generator was established earlier than our company. When we started selling massage chairs, they had been selling oxygen generators for several years.
Oxygen was founded in 1990, when they launched a portable oxygen generator, which uses the principle of chemical reaction.
The so-called oxygen generator is actually a plastic sink. The sink is divided into two parts, and the bottom is connected together.
When in use, add an oxygen generator to one side and a catalyst to the other side, and the two contact at the bottom of the tank, so that the oxygen generator reacts with water to produce oxygen.
The so-called oxygen generator is actually sodium percarbonate. When this kind of thing encounters water, it will undergo a chemical reaction to form sodium carbonate and hydrogen peroxide. Since hydrogen peroxide is unstable, it will decompose into water and oxygen.
The catalyst is manganese dioxide, which can accelerate the reaction process, thereby quickly obtaining a large amount of oxygen.
Sodium percarbonate is simple and convenient to make oxygen, and it 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, 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. So carbon peroxide once became a very important strategic material.
Since the means of industrial oxygen production have 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.
Since sodium peroxide reacts with water to generate hydrogen peroxide, this compound is also used as a bleaching agent and oxidizing agent in industries, such as chemical industry, papermaking, textile, printing and dyeing, food, washing and other industries.
Compared with it, it is a waste to directly use it to make oxygen. The hydrogen peroxide produced by one kilogram of sodium peroxide is more valuable than oxygen plus water.
So in the early 1990s, after Oxygen launched the oxygen generator, the first few years were tepid, because the price of the oxygen generator was too high.
An oxygen concentrator, including a pack of sodium percarbonate and a pack of manganese dioxide, can only be used for about fifteen minutes, but the price of this oxygen generator is five or six yuan. In terms of the income level of ordinary Chinese people in the early days, how could they afford it!
And those who can afford oxygen generators are the kind of people who don’t need to spend money in hospital. If they need oxygen, the hospital can send oxygen tanks to their homes with just a phone call. They don’t need this kind of thing.
It was not until the mid-1990s that the sales of Oxylide began to increase with the gradual increase of national income.
In addition, it was the hottest era of health care products at that time, and all kinds of exaggerated health care product advertisements emerged one after another, so it was easy to sell the products if the publicity was proper.
However, Oxide entered a glorious period after the rise of TV shopping.
In the late 1990s, domestic TV shopping developed rapidly. Even 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 many advertisements about Oxygen on TV, and they are all TV shopping programs. They have already made this product. If we make the same product now , isn't it too late?
Not too late. Li Weidong shook his head with a smile, and continued; You have to know that although their products are earlier, we have three major advantages.
First of all, we have the hospital channel. We have been operating the hospital channel for so many years, starting from the sale of massage chairs. Our representatives are very familiar with hospitals, and we also have cooperative relationships with many hospitals. This is something that other companies do not have. of.
Secondly, our brand awareness is relatively high. There are too many health care products that have emerged in the past few years. There are all kinds of everything, and most of them are brands that have never been heard of.
The Puppy brand is, after all, a well-known brand in China. If the same product has a brand bonus, it will be easier to gain the trust of consumers.
Thirdly, we are a professional manufacturer of medical devices. It is very important that we produce regular medical devices, not health care devices.
Because we produce medical devices, we can promote them according to medical devices, while other companies cannot.
If they do not have the qualifications to produce medical devices, or their products have not obtained the certification qualifications for medical devices, but they publish medical device advertisements without authorization, it is a violation of the regulations. We can report to the food and drug supervision department at that time, and we will definitely sue one by one!
Lu Guangming is also an old fritter in the mall. When he heard Li Weidong's last sentence, he immediately grasped the point.
Chairman, are you saying that Oxygen does not have the qualifications to produce medical devices? Lu Guangming asked immediately.
Li Weidong didn't give a clear answer, but said: How many of these domestic companies that produce health care equipment have medical equipment production qualifications? The production qualifications for medical equipment are not so easy to obtain.
Even if they have the qualifications to produce medical devices, are their products medical devices? Is there any certification qualification from relevant state departments?
If they do not have these, but advertise their products as medical devices, they are publishing medical device advertisements without approval, which is deceiving and misleading consumers.
At this time, the media will blow the wind and properly publicize the dangers of counterfeit medical devices. It is not certain who is Li Kui and who is Li Gui at that time!
False publicity was a common practice in the health care product industry at that time. How could there be any health product that did not make false claims? It can't be sold without false propaganda!
Many oral health products are promoting the efficacy of curing diseases, telling consumers explicitly and secretly that I am a medicine.
The same is true for health care devices, all kinds of explicit hints, exhausting methods to affix the labels of medical devices on themselves.
This is mainly caused by the irregularity of the domestic health care product market, which is regarded as a hidden rule of the industry. Although everyone does this, although it is a violation of the regulations, it is basically a state of non-compliance.
But if someone really reports it, then the law enforcement department will naturally do something.
Oxide is a member of the industry, and of course it is also doing such things, and it has continued for many years. Until 2006, the State Food and Drug Administration began to publish the Summary of Illegal Medical Device Advertisements, and Oxide was listed on the report.
The production qualification of medical devices is not easy to obtain. The state has relatively strict management in this area. Not just any cat or dog can get a medical device production license.
The production of medical devices also requires the qualification approval of relevant departments. Only when the competent department determines that what you are producing is a medical device, is it a real medical device.
These are not problems for Li Weidong.
Puppy Health chose to acquire Jinzhou Medical Device Factory instead of building a new factory. The main reason is that Jinzhou Medical Device Factory has complete medical device production qualifications and can pass the medical device production qualification approval relatively easily.
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 healthcare device, which one will consumers trust more?
And I can promote my products as medical devices without any scruples, but you can't do that. If you advertise a health device as a medical device, then go to the Food and Drug Administration to report it!
So when Li Weidong mentioned Li Kui and Li Gui, Lu Guangming instantly understood Li Weidong's intentions.
Lu Guangming thought in his heart: If we want to talk about insidious things, we still have to look at our chairman! The product is still in the mouth, and we will start counting competitors!
