On February 27, the Central Committee of the Democratic League announced 46 proposals to be submitted to the National Committee of the Chinese People's Political Consultative Conference. Among them, a proposal titled "On Concentrated Rectification of the Pseudo-Tech Market and Purification of the Technological Innovation Environment" was proposed. Over the years, pseudo-tech products such as dark matter shampoo, quantum pendants, negative ion ceramic tiles, graphene underwear, and nano massage chairs have been on the market. The Internet is rampant, harming the interests of the masses, at the same time impacting genuine scientific and technological innovation products and disrupting the scientific and technological innovation environment. As soon as this news came out, it caused an uproar in the ceramic industry.
Anion tiles, a popular product in the ceramic industry, have been questioned as "pseudo-technology" and the market chaos has attracted attention from the outside world. This has undoubtedly sounded a wake-up call to the industry: seeking truth from facts and operating with integrity are the foundation of an enterprise. Loss of integrity will inevitably lead to market condemnation and legal accountability. At the same time, it also exposes many problems such as the current disorderly market competition in the ceramic industry and the lack of self-discipline in the development of some enterprises.
Technological innovation, material revolution, and green building materials are the inevitable paths for breakthrough development in the ceramic industry. "Technology, green + ceramics" gives ceramic products and home life more possibilities, and is also the general trend for China's ceramic industry to become bigger and stronger. .
In response to this incident, many industry insiders stated that it has been nearly 20 years since the birth of negative ion ceramic tiles, and the feasibility, scientificity, safety and environmental performance of the product have been repeatedly demonstrated by authoritative experts and quality inspection agencies. , has long been proven not to be a “pseudo-technology”.
However, we need to be alert that the chaotic and disorderly development of negative ion ceramic tiles has been around for a long time. Due to long-term lags and loopholes in market supervision, industry standards, product testing, etc., some unscrupulous merchants have made false and exaggerated publicity, making this product full of Questioned, criticized and complained by all parties, in the long run, a trend of "bad money drives out good money" has been formed, which has caused a negative image and "crisis of trust" that is difficult to repair for the development of the anion ceramic tile category. From a long-term development perspective, centralized rectification , orderly development has become a top priority.
Only a few can be genuine
Purifying the market environment has become a top priority
The Democratic League Central Committee’s proposal is about to come out and has attracted great attention from the ceramic industry. Miao Bin, president of the China Building and Sanitary Ceramics Association, said that the specific content of the proposal highlights the screening of negative ion ceramic tiles. The intention is good and the starting point is to "concentrate on rectifying the pseudo-tech market and purify the technological innovation environment." The reason is It is difficult to distinguish the authenticity of negative ion ceramic tiles currently on the market, there is a lot of chaos, and national supervision does not know where to start.
One of the inventors and professor of negative ion ceramic tilesTang Qi, a senior engineer and the drafter of the negative ion ceramic tile group label, believes that the proposal of the Democratic League Central Committee is a good thing for the development of the industry. He has been calling for the purification of the negative ion ceramic tile market environment for many years.
Tang Qi recalled that the State Administration for Market Regulation had conducted three large-scale spot checks and found that unqualified negative ion ceramic tiles can be divided into two categories: one category only has negative ions written on the packaging, but the product itself cannot induce negative ions. Negative ions, this belongs to the category of false propaganda; the other category is to add negative ion powder to products without doing any research. Although it can induce negative ions, it will also bring about new problems of excessive radioactivity, which is unscientific. .
Tang Qi pointed out that the real negative ion ceramic tile is undoubtedly a high-tech product, but currently only a few on the market are genuine.
Li Jiadoo, a senior engineer at Dahong Glaze and an expert on the standard evaluation of negative ion ceramic tile groups, also said with certainty that negative ion ceramic tiles are definitely not "pseudoscience". The reason why it has been questioned is that negative ions are "invisible and intangible", which has been exploited by some undisciplined companies, resulting in an endless stream of fake and shoddy negative ion ceramic tiles on the market, causing a lot of trouble to consumers.
Li Jiado believes that promoting the healthy and benign development of the negative ion ceramic tile category requires the efforts of all parties in the industry and society. First, the existing group standards for negative ion ceramic tiles must be publicized and strictly implemented. Each company must have an authoritative test report during the sales process; second, ceramic companies must strengthen self-discipline, strictly select materials during the production process, and Strictly indicate the production process; third, vigorously strengthen intellectual property protection and support government departments to increase supervision.
Liang Jian, deputy director of the National Daily and Architectural Ceramics Engineering Technology Research Center of Jingdezhen Ceramics University, also affirmed that negative ion ceramic tiles are a high-tech product, but he also pointed out the chaos in the market, such as negative ion-induced The amount is too small to achieve the effect of purifying the air, and the blind pursuit of the amount of negative ions induced leads to excessive radioactivity, and there are also products that reduce the amount of negative ions after one or two months of use. These are negative ion ceramic tiles that do not meet the standards. In turn, Said that real negative ion ceramic tiles need to meet three conditions at the same time: "the amount of negative ions induced is sufficient, it meets the national safety standards for radioactivity, and it can continuously induce negative ions".
Make negative ion ceramic tiles
Long-term, solid basic research is needed
According to industry insiders, negative ion ceramic tiles are a "late bloomer" product. As early as 2003, the first negative ion ceramic tile sample was produced. However, in subsequent market promotion, negative ion ceramic tiles received a cold reception. Once "hidden" by the industry”For more than ten years.
It was not until 2015 that consumers paid more attention to health, greenness and environmental protection, and it once again attracted widespread attention from all walks of life. But even so, many people in the ceramic industry are unable to describe in detail the product characteristics and functional principles of this type of product.
What is the principle of negative ion tiles? According to Tang Qi, true negative ion tiles have a micro-electric field on the surface of the product. In fact, the development of negative ion tiles is the development of micro-electric fields on the product surface, which induce negative ions through the micro-electric field on the product surface.
Second, why is it said that negative ion ceramic tiles can purify the air? Because people can smell odors such as organic macromolecules such as formaldehyde, as well as particulate matter such as dust and PM2.5 in the air. In a micro-electric field environment, these organic macromolecules and particles will agglomerate and settle, thus purifying the air. these harmful substances.
It can be seen that the micro-electric field on the surface of the product is the key technology to induce negative ions and purify the air. To form a micro-electric field, the main basic raw material used is tourmaline. However, in an environment of 850-950°C, the structure of tourmaline will be destroyed and its performance will be lost. Therefore, it is necessary to master the key to maintaining performance after high temperatures. technology.
Tang Qi said that he began to develop negative ion ceramic tiles in 2003. To truly develop negative ion ceramic tiles, how to determine the effective range of negative ion induction and how to verify it requires long-term basic research, which is very important in the industry. The weak link.
Li Jiadoo is also deeply touched by the weak basic research in the ceramic industry. He pointed out that the ceramic industry is very lacking in high-end technical talents, and academicians are even rarer. Moreover, many technical personnel are often unable to settle down and cannot concentrate on deep cultivation in a certain field. . The failure of basic research to keep up is an important source of chaos in the anion ceramic tile market.
Liang Jian also said with emotion that there are few talents in the industry studying the basic principles of negative ion induction, and many companies are "free riding" to hype the concept. However, he believes that with the emergence of positive phenomena such as the increase in social attention and the establishment of industry group standards, the negative ion ceramic tile market will become more and more standardized in the future, and the industry's technological innovation environment will become increasingly purified.
Development has gone through twists and turns
Falling into a crisis of trust due to "chaos"
In fact, from obscurity to industry carnival to return to rationality, and now being questioned by the outside world, the development of negative ion ceramic tiles has gone through many twists and turns.
In the early days, negative ion ceramic tiles were only distributed to a few ceramic companies. But in 2017, the "carnival door" was pushed open. At the Foshan Autumn Ceramics Expo alone, more than 20 ceramic companies emerged to promote negative ion ceramic tiles. Subsequently, this crazeIt quickly spread to all parts of the country, and ceramic production areas such as Shandong and Jiangxi Gao'an also ushered in the climax of promoting negative ion ceramic tiles.
In 2018, there was even a hot situation at the Jiangxi Gaoan exhibition where "the city was full of negative ion ceramic tiles". At its peak in 2018, Faku, Liaoning, the largest architectural ceramic production area in Northeast China, had an output of more than 100 million square meters producing various ceramic tiles with negative ions as a selling point, accounting for 10% of the overall output of the Faku ceramic production area that year. More than half.
After the carnival, reason comes as promised. The watershed year is 2019. Less than 10% of ceramic companies in the Gao'an ceramic production area are still sticking to the negative ion ceramic tile position. The total output of negative ion ceramic tiles in the Faku ceramic production area has also rapidly dropped to more than 10 million square meters. As well as the Foshan Ceramics Expo It is no longer difficult to find traces of negative ion ceramic tiles at exhibitions such as the Guangzhou Industrial Exhibition and the Guangzhou Industrial Exhibition.
Looking back now, the chaos of negative ion ceramic tiles reached its peak during that "carnival period". At that time, many manufacturers who were fishing in troubled times used low-quality negative ion powder to reduce costs, or did not use it at all but still used the banner of negative ion ceramic tiles. Some manufacturers gave ridiculous explanations when faced with random inspections by the industrial and commercial authorities. "Cartons contain negative ions". It is precisely because of the interference of many spoilers that the negative ion ceramic tiles are in chaos and chaos in the terminal market. They are subject to more and more doubts, and the negative impact of the category is accumulating day by day.
In addition, negative ion ceramic tiles are "invisible and intangible" and require professional equipment testing, which can easily make consumers feel distrustful. Some businesses are eager for quick success and quick profit, and instead of scientifically promoting and verifying their products, they instead It boasted outrageously, and even exaggeratedly promoted that "negative ion tiles can treat hair loss, refresh and strengthen the spleen", which made the negative ion tile category discredited by the people, and also made the real negative ion tiles suffer injustice for no reason.
For negative ion powder, Tang Qi said that he never recommends it, because in order to achieve the effect of inducing negative ions, the powder needs nanometer fineness. This will first cause inhalation dust problems, and secondly it will be very difficult. Control radioactivity issues. "If negative ion ceramic tiles do not consider radioactivity first, then the product and industry will definitely be ruined."
After the storm, the anion tile market has gradually returned to rationality, and most manufacturers that produce and sell anion tiles have withdrawn. However, as of the end of 2020, the manufacturers and sellers of negative ion ceramic tiles on the market are still quite large. According to incomplete statistics, there are more than 170 brands and trademarks using "negative ion ceramic tiles" in the Foshan production area alone, but different manufacturers have Product quality and functional effects are still goodUneven.
From "chaos" to "governance"
Standards, systems, and supervision are gradually improving
From "chaos" to "great governance", another landmark event that anion ceramic tiles gradually move toward standardized development is that on February 15, 2020, after two years of painstaking research and countless experimental tests by relevant research units, China The Building and Sanitary Ceramics Association officially released the association group standard "Ceramic Tiles that Can Induce Air Negative Ions" (T/CBCSA 14-2020) for negative ion ceramic tiles. This standard specifies the terms and definitions, classification, technical requirements, test methods, inspection rules, marking and instructions, packaging, transportation, storage and other matters of ceramic tiles that can induce negative air ions.
Among them, the definition of negative ion ceramic tiles is "ceramic tiles that can continuously induce a certain amount of air negative ions to purify the air under normal conditions of use, referred to as negative ion ceramic tiles". It can be seen that its important prerequisites are " Under normal use conditions, continue to induce a certain amount, and purify the air."
The standard not only stipulates that "the purification rate of formaldehyde in the air is not less than 50%" for air purification, but also stipulates a "certain amount", that is, the amount of negative ions induced in the air (C) should not be low At 500 ions per cubic centimeter (ions/㎝³), it can be understood that this is the entry threshold for negative ion ceramic tiles. Based on this, it is divided into three levels. Level one refers to C＞1500, level two refers to 800＜C≤1500, and level three refers to 500＜C≤800.
As for the radioactivity that consumers are very concerned about, the standard stipulates the radionuclide limit for negative ion ceramic tiles, that is, the internal exposure index Ιr should not be greater than 0.9, and the external exposure index ΙRa should not be greater than 1.2.
The introduction of the association's group standards has filled the gap in the lack of standards for negative ion tiles. It has also solved the problems of inconsistent testing standards for negative ion tiles, unclear data results, and no basis for market supervision and regulation. More importantly, it has safeguarded the rights of consumers. Provides valid basis.
Many consumers who bought special negative ion tiles said that before purchasing, they were also worried that the ability of negative ion tiles to purify the air was just a publicity stunt, but after searching online or being introduced by shopping guides, they made the decision to purchase. Now, they will take the initiative to recommend negative ion tiles to their relatives and friends. I heard that the China Building and Sanitary Ceramics Association issued an agreement on negative ion ceramic tiles.Consumers have expressed their support for this group standard and said that this standard will make them feel more confident when buying negative ion ceramic tiles.
