At the beginning of August, Zhejiang Dongyang Consumer Rights Protection Committee issued a consumer warning: warn that the water heater is “overdue serviceâ€; once the water heater has exceeded the service life of 8 years, it must be replaced as soon as possible. The previous Shanghai Consumer Protection Committee also issued the same warning. However, the reporter visited and found that for the over-aged water heaters, many residents still have the attitude of “remaining useful, abandoning the pityâ€, and the safety awareness is weak. Even some water heaters are not installed in accordance with national standards, and they are still in use. A safety leakage bath with a large hidden danger is not optimistic.
In this regard, relevant experts pointed out that in addition to changing the safety awareness of residents, it is necessary to strictly implement various safety standards set by the state.
Water heater "overage service" hidden danger
It is understood that in view of the potential safety hazards such as water leakage, leakage, and air leakage, the Consumer Protection Committees across the country have issued consumer warnings. Once the water heater has been used for more than 8 years, it must be replaced as soon as possible. The electric water heater of the anti-electric device avoids the safety hazard caused by the aging of the equipment.
Relevant experts of the China Consumers Association also pointed out that most of the current electric water heater safety accidents include the reasons that the water heater is overaged, the line is aging, the inner tank leaks, and the water heater does not have the anti-electric wall technology specified by the national standard. The cause of the leakage protector. "And such a leakage protector is often difficult to play a protective role." The above experts said. When the user's home line is aging, or when the live wire is reversed, the leakage protector not only fails to protect, but also “leads into the roomâ€, causing an electric shock. Moreover, this type of leakage protector is more commonly used in water heaters. Therefore, he urged water heater manufacturers to choose a protective anti-electric wall device to ensure the safety of users.
The reporter learned that the "anti-electric wall" is a national standard formulated by the China Household Electrical Appliances Standardization Committee in 2007. It is developed by Haier water heaters for the use of non-grounding lines, aging lines, water pipes as ground lines, and inferior switches and sockets. The patented technology not only completely insulates the current in the heated inner tank caused by the leakage of the heat pipe, but also isolates the damage caused by the ground wire or the water pipe.
In 2008, after the anti-electric wall became the national standard, it passed the series of validation procedures of the International Electrotechnical Commission meeting and was officially written in the latest version of the "Special Requirements for Safe Storage Water Heaters for Household and Similar Electrical Appliances".
Experts recommend water heaters to identify the anti-electric wall
The principle of "anti-electric wall" is simply equivalent to installing a large resistance between the human body and water. Once a leakage phenomenon occurs, this "resistance" can decompose the voltage to avoid an electric shock accident. According to the relevant person in charge of Haier water heater, the experiment shows that even if 220V voltage is applied to the inner tank, it will not cause any harm to the human body after the action of "anti-electric wall".
According to a set of statistics, the patented technology of Haier's anti-electric wall was not only accepted as an international standard, but also created a record of 25 million accidents. It can be said that the "anti-electric wall" is the first national standard in the history of Chinese household appliances transformed from enterprise patents, and the first national standard in the water heater industry based on China's national conditions.
It is also under the support of such safety technology that Haier water heaters have completed energy-saving and intelligent changes in the industry based on the actual needs of users. According to information released by the British Institute of Building Services Research and Information (BSRIA), the world's leading independent research organization, Haier water heaters ranked first in the global sales of all categories and electric water heaters with a market share of 9% and 17% respectively. At the same time, the world's influence organization also named Haier water heaters as "world famous brand" products.
In this regard, industry analysts believe that with the continuous development of society, the consumer demand of users is constantly changing. But in this ever-changing consumer demand, the only constant is the security demand, especially for water heaters that involve both water and electricity, safety is always placed first. Therefore, he suggested that users purchase water heaters, should look for the national standard for anti-electric wall, to avoid unnecessary safety hazards to users.
The refractive index of the monocrystalline silicon material is about 3.42, and the reflectivity of the silicon lens after polishing is about 30% in the air environment. Our common silicon lens and silicon window can be coated on the surface (Antireflection Coating), which can reduce the reflectivity to less than 1.5% between 3 to 5 um.
Some silicon elements, especially the silicon protected windows, are exposed to dust, acid, salt and so on in the harsh environment. The conventional multilayer antireflection coating will be damaged and affect the normal work of the equipment. At this time, we need to make DLC coating on the surface of the silicon lens.
Diamond-Like Carbon (DLC) Coated Silicon Windows are engineered for 3 to 5µm, making them ideal for infrared defense applications such as thermal imaging.
Diamond-Like Carbon (DLC) Coated Silicon Windows provide anti-reflection coating on one surface and a specially designed DLC coating on the other surface, making these windows highly durable and ideal for harsh environments.
