Gianna Jun Bingbing female female kiss on the same stage fighting Yan who are more challenged electric hot water heater heater on three major issues - namely Ogilvy questioned three metal cup hot water heater heater heater is the most critical issue that thermoelectric heater element , the current market, there are three important uses: metal goblet heaters, non-metallic heater, flat-electric film heater. For the market to sneak some manufacturers of metal goblet heater exaggerated adcraft food warmer propaganda, Zhongshan Ogilvy special electrical technology department to investigate metal heater under the "wonderful" where: Q: The manufacturers claim that the use of such heaters are truly The water separation, in fact it? Metal goblet heater: such as stainless steel goblet, adcraft food warmer copper goblet, also known as NIC fever skills, adcraft food warmer it is miniaturized storage-type electric water heater heating method, adcraft food warmer which is simply the same principle: that the electric tube inserted into the cup volume, adcraft food warmer the soaked in water heating, whether U-shaped heating tube is to take a straight rod or arrangement, adcraft food warmer heat soaking in water is essentially helpless change, therefore, that using a metal cup heater manufacturers claim that is truly separate hydro argument is basically nonsense. Second question: the use of such a heater manufacturers claim that even small scale never scaling, the exact case? We know the cause of the first scale to the form: Because a certain number of water soluble calcium and magnesium salts, such as bicarbonate, carbonate, sulfate, chloride, phosphate, etc., salts of these physical process occurs in the heat and chemical changes caused by scale. Accordance with the relevant adcraft food warmer physics research shows: the formation of scale need to satisfaction of two conditions: adcraft food warmer water temperature in degrees over a longer time;, absolutely insist on still water, and the water quality of the scale also has a major impact: the stronger alkaline water more easily knot dirt. Test confirmed: Scaling is no association with the materials used, we used to open the bottle, the same will not scale it? We all know that the water heater will be set to cover over-temperature, however, due to the heater even after the end of the heating, the fever is still a large number of heat required to wire wrap hair, so the temperature of the heater surface easily reach degrees or more, while heating There is always a certain amount of water is present, so that scaling will not be prevented, so no matter what kind of heater is impossible without fouling, which manufacturers adcraft food warmer claim if never scaling, it is a very irresponsible Fraud and mature. Then, using an electric heater pipe to heat the metal, the degree of fouling and how it? Electric hot water heater in KW power over ordinary applications to heat the metal heating tube electric heater tube if it is U-shaped, roughly as - group, straight rod arrangement is the root, the total length of the CM-CM The total surface of the C-C square meters, the unit power negative Heda WW / C , once stagnant heating, thermal inertia is great, need to distribute large amounts of heat, the surface temperature is high, the long-term overload, its life large To reduce, while scaling phenomenon greatly increased, especially adcraft food warmer in China's northern region water hardness large, the number of months at least, as much as a year, will be attached to the surface of heating tube thick layer of CaCO,. This greatly affects the heat transfer effectiveness, while CaCO due to thermal expansion coefficient and a large stainless steel is not the same, then the inevitable burst, leakage wounding would not be strange, and nearly two years of near-thermal electric water heater sales compared to the geographical concentration of such products leakage wounding incident occurred and both are using the metal goblet adcraft food warmer heater. In addition, the severity of fouling with water about: In northern China, water hardness is large, very broad scale and more significant; serious adcraft food warmer level of fouling and also heating the surface of the heat load related, the greater the heat load, scaling The more opportunities there would be more serious. Seen in this light, the metal goblet heater in the present situation, compared to other heating element, which is the most severe fouling in southern China also said they were not obvious. Few metal goblet heater fouling claimed never even scaling it is a big rumor. Three questions: heater manufacturers claim that the use of such corrosion resistance and longer life, really predicament it? Metal will corrode, which is based on knowledge of the individual, is the scene of a metal by chemical or electrochemical effects of environmental media being damaged. Corrosion of metals throughout the various areas of the national economy and to the national economy has brought huge losses. In the industrial developed countries, the annual corrosion rusty steel production accounted%, about percent of the equipment due to corrosion and scrapped. In China, because of metal corrosion caused economic loss of up to billion annually, accounting for% of gross national production. For a long time, people are always using a variety of techniques to maintain the metal to avoid corrosion and fall produce. One of the most effective anti-corrosion of metal equipment, the most common way is coated with anti-corrosion coating metal surfaces to cut off the corrosive adcraft food warmer medium and the metal substrate. And this anti-corrosion coating at first glance because of the cold temperatures Chad long hot extreme temperature situations can easily be destroyed in the metal cup-shaped heater, there are two areas that need anti-corrosion technology: one metal cup wall, and the other is heating tube surface. adcraft food warmer And these two premises is a long-term contact with water, and great temperature difference between hot and cold temperatures long, plus the impact of fouling, adcraft food warmer corrosion way that normal meaning there is not much carelessness, especially heating pipe, followed by the use of time goes, wall thinning is not the new thing, so corrosion resistance and longer life of the reason lie? Metal cup wall and the heating pipes in the name of the data, the general L, L labels pipe, pipe anti-corrosion performance of such center, and some manufacturers adcraft food warmer began using pipes, high cost, and the remaining metal goblet heating it to a certain extent than the market's is life in minor corrosion and strong, but with the imminent electric hot water heater under this particular environment, its performance is not significant. In summary, with the imminent metal goblet heater electric water heater is still in practice in terms of the actual situation is not ideal, the existence of many of the insurance risk, and the use of this type of heater manufacturers turned to conceal the phase, but also deliberately exaggerated his word, but also a right to spend on life's negligence!
