China Radio International Beijing November 4th News (Reporter Shao Lanjie) Since announcing cooperation with Aerospace Bio in 2021, Angel has been making frequent moves in the past year. Recently, he signed a contract with Hainan Aerospace and launched a new product equipped with aerospace water purification technology. With the support of the concept of "aerospace", Angel water purifier continues to explore the high-end market, and the price has also risen to more than 10,000 yuan.
Aerospace Technology represents the top technology in the industry in the eyes of consumers. It is equipped with a high-end water purifier of aerospace technology. What is the water purification effect? China Radio International reporter investigated this.
is more than 5,000 yuan expensive, and the water purification effect is similar. According to the official website of Angel , it began to get involved in high-end water purifiers in 2016, and launched high-end water purifier A6 that year, and launched A7 in 2019. The Angel A7 series is equipped with aerospace water purification technology, among which two aerospace water purification technologies have been applied to the X-Tech series.
In order to more accurately understand the water purification effect of Angel Aerospace Technology, a reporter from China Radio International purchased Angel's ordinary water purifier "Rude's Cube 600G" and Aerospace joint A7Pro from regular channels, with prices of 2,298 yuan and 7,449 yuan respectively. We will find out through the sample delivery test of a third-party testing agency.
The third-party testing agency takes GB 5749-2006 "Sanitary Standards for Drinking Water" as the testing standard, with a total of 38 testing projects. Judging from the three test results of tap water, ordinary water purifiers, and aerospace joint water purifiers, the test results of tap water and ordinary water purifiers in 23 projects are consistent, and there are obvious changes in 16 projects including fluoride, nitrate (in N)/nitrate nitrogen, trichloromethane, chlorate (when using chlorine dioxide disinfection), pH/pH value.

From the statistical table, it can be seen that in many key projects, tap water and purified water have obvious changes. For example, the total hardness has been reduced from 128mg/L to
. Comparing the test results of Angel's ordinary water purifier and the aerospace joint water purifier, it can be found that among the 38 tests, only 6 items have changed their values, of which five of them are slightly rising. Theoretically, the better the purification effect, the smaller the value of most test items.

From the above comparison chart, it can be seen that the values of the Aerospace joint water purifier in nitrate/nitrate nitrogen, zinc, chloride , sulfate , and oxygen consumption are higher than those of ordinary water purifiers. It can also be understood that the purification effect is weaker than or equivalent to that of ordinary water purifiers.
In the product description of A7Pro, its core selling points are long-term reverse osmosis filter element, aerospace antibacterial technology, patented ACF composite filter element, double-head independent water outlet, intelligent mechanical lamp faucet, and ultra-low wastewater ratio.
An Angel staff member from a home appliance store introduced, "There are three models of the A7 series, namely A7, A7lite, and A7Pro. Their water purification effects are similar. The difference is that A7PRO is a space co-branded model, with an booster valve . The outside is made of metal bronze, and the water volume will be larger." But the above staff cannot explain clearly what technologies are used in the aerospace joint. The reporter investigated online and offline channels and found that after the promotional activities were superimposed, the purchase prices of A7lite and A7Pro consumers were about 5,999 yuan and 7,999 yuan, with a price difference of 2,000 yuan.
Compared with the ordinary water purifier "Rude's Cube 600G", the price of A7Pro is more than 5,000 yuan. In terms of configuration, in addition to the drinking water purifier, A7Pro has an additional daily water purifier . The functions of this device can also be realized through Angel pre-filter, which is between 399 yuan and 1,298 yuan.
How many aerospace elements are there? On the JD
JD platform, the relevant product page of Angel Aerospace joint branded model shows that the six major aerospace water purification technologies jointly developed by Angel and Aerospace Bio are: positive potential antibacterial materials, Angel's proprietary long-term RO membrane components, UVLED ultraviolet disinfector, Angel spiral stacking, Angel's independent full bass isolation pump, and purifier assembly technology.
Among the many patents displayed on Angel's official website, "a laminated filter element, laminated filter and beverage purification equipment" patent was applied for on July 21, 2020. The authorization announcement date is May 7, 2021. The abstract stated that the laminated filter element, laminated filter and water purification equipment provided by this utility model have the following advantages, which improves the water purification effect and ensures water purification efficiency.
"A reverse osmosis membrane element and water purification device with it" patent filing date is April 2, 2018, and the authorization announcement date is May 29, 2020. It can be seen that this core technology related to water purification has applied for a patent before reaching a cooperation with Aerospace Biology in 2021.
Angel described one of the characteristics of the "Nezha 600G household direct drinking water purifier" on its official mall as "aerospace-grade nano-anti-bacterial antibacterial properties of four-point zinc oxide whiskers" and stated that the technology comes from "China's utility model patent a method to improve the antibacterial properties of four-point zinc oxide whiskers", but after query on relevant websites, the person of the above patent application (patent rights) is Chengdu Jiaotong University Jingyu Technology Co., Ltd., which was applied in January 2012 and authorized in January 2014.
In March 2021, Angel and China Aerospace (Aerospace Biology) held a cooperation signing ceremony in Beijing, and the two sides cooperated to jointly establish a joint aerospace water purification laboratory.
Aerospace Biotechnology, namely Aerospace Shenzhou Biotechnology Group Co., Ltd., is affiliated to China Aerospace Science and Technology Group Fifth Academy . It was previously , which owned ,100% wholly owned , and introduced Beijing Runwu Oriental Biotechnology Co., Ltd. in February 2019. Currently, both parties hold 250% of , which is a subsidiary of China Resources Group .
official website shows that Aerospace Biotechnology takes biomedical as the core of the industry, develops biohealth products and seed industries, and is committed to establishing the "Aerospace Bio" brand. The aerospace biological business areas include biomedicine, biohealth products and seed industries, mainly engaged in space biology research and industrial product development, and most of the subordinate companies are in the fields of biotechnology and agricultural breeding.
Dr. Shi Wanglin attended the signing ceremony on behalf of Aerospace Biology in 2021. Dr. Shi Wanglin once used an aviation breeding expert to provide the theme report on "Aviation Breeding Application" to the outside world, introducing the development history of aviation breeding in China. A year later, on September 1, 2022, the world's first joint aerospace water purification laboratory jointly created by Aerospace Biology and Angel officially unveiled. Relevant people attended the event include Director Wei Yuliang of Aerospace Biology, Dr. Lu Jinying of Aerospace Biology, and Dr. Li Huasheng of Aerospace Biology.
China Radio International reporters found that Dr. Lu Jinying is the director of the Space Plant Research Office under the Space Biology. His work is to lead the team to carry out various varieties breeding, space mutagenesis and other experiments. Dr. Li Huasheng and Dr. Lu Jinying are related to the research field. The two parties have jointly published papers "The Effect of Aerospace Environment on the Expression Stability of Internal Reference Genes in Arabidopsis Seedlings", etc. Judging from the information that can be found at the attendance, whether it was Shi Wanglin a year ago or Lu Jinying and Li Huasheng this year, the research field of the above-mentioned people has a certain span with Angel's drinking water industry.
html In September, Angel announced the signing of a contract with Hainan Aerospace. According to public reports, Lin Fangxian, deputy general manager of Hainan Aerospace Investment Management Co., Ltd., and Zhao Kai, vice president of Angel Group, signed on behalf of Hainan Aerospace and Angel respectively.Hainan Aerospace Investment Management Co., Ltd. once established two subsidiaries, namely Wenchang Aerospace Real Estate Co., Ltd. and Hainan Huanyu Aerospace Technology Co., Ltd. (formerly known as "Hainan Wenchang Aerospace Real Estate Co., Ltd."), which have been cancelled, but from the perspective of the company name and business scope, the two subsidiaries are concentrated in real estate development and engineering construction.
In 2012, Hainan Expressway Co., Ltd. (hereinafter referred to as " Hainan Expressway ") held 25% of shares of in the form of capital increase investment. The announcement at that time stated that "Hainan Aerospace Investment Management Co., Ltd. is the carrier of the comprehensive strategic cooperation between China Aerospace Science and Technology Corporation and the Hainan Provincial Government. It shoulders the glorious mission of inheriting the spirit of aerospace and building the supporting area of Hainan Aerospace Launch Field."
Hainan Aerospace Launch Field Support Area was considered to change the layout of Hainan Tourism East Line and become a new landmark for Hainan Tourism. Hainan Expressway's main business is real estate, tourism, infrastructure, etc. It explained that "the capital increase is mainly to broaden the company's business scope, and to enter the characteristic tourism service industry with the help of the Hainan Aerospace Launch Station supporting area project undertaken by Hainan Aerospace Company."
The latest news is that on September 28, Hainan Aerospace and East Road Farm Company held an industrial exchange symposium to conduct in-depth exchanges and discussions on the industrial model of "leisure agriculture + rural tourism + popular science education" and build an agricultural industrial park demonstration site full of aerospace elements.
Judging from the above information, Hainan Aerospace Investment Management Co., Ltd.'s main business has not had much correlation with technology for a long time. In the 2022 interim report of Hainan Expressway, among its joint ventures and associates, the business nature of Hainan Aerospace Investment Management Co., Ltd. was described as a "service industry", with the latter's operating income of approximately RMB 16,500 and its net profit of RMB -813,600. What is the performance of RO film , the self-developed
?
In the publicity, Angel said that for a long time, the core component of the water purifier, the reverse osmosis membrane, has mostly relied on foreign technology, and the long-term reverse osmosis filter element it developed has broken the situation that membrane technology is monopolized by foreign brands. According to its official website, "In terms of performance, long-term reverse osmosis filter elements comprehensively surpass foreign brand filter elements: their desalination rate can reach 95%, while the originator of RO membranes in the United States is only 86%. "
In household water purifiers, RO membrane reverse osmosis is the mainstream water purification method. Reverse osmosis originated from the research of aerospace technology in the 1960s in the United States, and later gradually converted to civilian use and widely used in beverages, seawater desalination and other fields.
desalination rate RO membrane is a major technical indicator, which refers to the percentage of the concentration of soluble impurities removed from the system's inlet water through the reverse osmosis membrane. A practitioner said that the desalination rate of reverse osmosis membrane was determined during its manufacture and forming. The nominal desalination rate of each company is very high, but due to the actual use environment and the quality of the raw water, the actual desalination rate will generally remain at around 95-98%. Another water purifier professional reminded, "The RO diaphragms of the initially installed machine are all dry films, with a slightly lower desalination rate and a slightly higher effluent TDS. After a few days of use, the RO film is fully soaked and matured, the effluent TDS will drop." He mentioned that the national standard for desalination rate of RO films shall not be less than 90%, and generally can be above 95%. It is a dynamic value, which is related to factors such as water pressure, water quality, water production stage, and membrane use time.
China National Radio reporters checked mainstream water purifier brands, and most of them claimed that their desalination rate can reach 95% or above. The originator of the RO membrane in the United States is Dow . Some domestic water purifier brands that use Dow RO said that their desalination rate is more than 98.5%. In fact, Angel's strategic new A6 water purifier launched in September 2014 is also equipped with "original imported Dow filter element in the United States".
Angel said that the long-term reverse osmosis filter element was developed independently by its "invested 150 million yuan in three years and a team of more than 200 scientific research experts." According to the patent query results, Angel's "a reverse osmosis membrane element and a water purification device with it". The patent application date is April 2, 2018, and the authorization announcement date is May 29, 2020. According to the description, "the structure of the invention is simple and can extend the service life of the reverse osmosis membrane element."
In the water purifier, an important indicator is water efficiency, that is, the water purification rate of aquatic products. After tap water is filtered by the water purification equipment, the ratio of the water purification to raw water is the "water purification rate" of the water purifier. On July 1, 2022, the new version of the national water efficiency standard GB34914-2021 "Water Purifier Water Efficiency Limit Value and Water Efficiency Level" was officially implemented.The new national water efficiency standard has changed the five water efficiency levels of the old national standard to three levels. The water purification rate of the lowest level must be greater than or equal to 45%, which is 15% higher than the old national water efficiency standard. The water purification rate of the highest level must be greater than or equal to 65%.

Angel said in A7lite's publicity that the national first-level water efficiency is 65%, and the A7lite's tested water efficiency is 68.5%, so "supremn-level water efficiency". But in fact, in the new national standards, 65% is just the threshold for first-level water efficiency, and 65% or more can be called first-level water efficiency. There is no recognition and statement of "super-national first-level water efficiency".
