The fatal weakness of Brazed Radiator is the most afraid of alkaline water corrosion
Computer CPU Brazed Radiator not only to the pursuit of super heat capacity, but also to the user with excellent experience. Using the new PWM cold control technology to achieve low-temperature energy-saving operation, the technical features: low temperature working conditions, both effective cooling and cooling, but also reduce energy consumption, energy saving call.
From the frequent leakage accident, people finally clear that the Brazed Radiator most afraid of alkaline water corrosion, nearly 10 years of use to prove that the coating is not reliable corrosion, can not fundamentally solve the problem. Did not seize the key issues, effortlessly, scattered people regulate the heating water quality and operation and management efforts.
We are the first system in China after the introduction of China, we are on this basis to agents and marketing to become independent research and development in China to build one of the leading brands, and the first to push this to the international market. The traditional cast iron Brazed Radiator is mainly in the production process environment is relatively poor, is not conducive to environmental protection, the other is relatively heavy. In the heating of the cast iron state requirements require the inner wall to be made of sand treatment, if the interior wall of sand on your future single-household dose, a variety of instruments, including your temperature control valve body, these related accessories are not easy to save energy.
Some people say that the current heating system of alkaline water quality is the impact of Brazed Radiator "original sin" one, this is wrong, unscientific, not objective. Brazed Radiator fatal weakness is the most afraid of alkaline water corrosion, which is due to its metal caused by the theoretical chemistry courses in secondary schools have learned to know, do you forget it? Positioning Brazed Radiator Development of the "crime"! For any material are used to avoid its short, the Brazed Radiator is clearly used conditions: only for PH = 5-8 neutral hot nickel water. To seize this fundamental point, you can handle a variety of situations: most of the north of the boiler direct use of water, PH = 10-12, can not be used, two pairs of its heat exchange after the secondary water PH = 5-8, Available; on the south, north use the gas boiler independent heating system, neutral water PH = 5-8, available. For hot water that exceeds this range, only use of waterways for copper, stainless steel or steel and composite Brazed Radiator, Brazed Radiators with corrosion inside the coating are also available, but not insured.
China's Brazed Radiator industry brand awareness gradually increased. At the beginning of this century the state of the domestic Brazed Radiator business conducted a survey, most manufacturers small size, production capacity is relatively low, the technical level is poor. The domestic Brazed Radiator manufacturers to establish their own brand awareness gradually increased, Brazed Radiator market in the past, the chaotic situation has gradually improved.
After several years of practical use, it was found that the shortcomings of the Brazed Radiator, is the use of steel pipe Brazed Radiator after a period of time, easy to leak in the weld problems. Experts in the careful analysis found that there are two main reasons: the first objective factors, the introduction of the product is not fully consistent with China's national conditions, China's current heating operation and management is also very irregular, heating water quality is not good, water oxygen High, easy to oxidize the corrosion of steel; the second subjective factor, the introduction of the product is made of thin steel plate through the roll welding process, the solder joints too much, the weld is too long. ① the head (that is, the water separator) is a two thin steel plate were rolled and then welding and forming, the formation of the first week of the first piece of the weld, including the top of the head of the Department of water at the top of the weld; ② riser is thin Into the tubular, with the welding method will be welded to form a steel pipe; ③ then the riser and head welding into a single Brazed Radiator; ④ Brazed Radiator single-chip connection is welded, and finally formed Group of Brazed Radiator. During the heating, it is often not full of water, the upper part will appear air layer; in the stop heating after the water vent, the bottom of the head there will be residual water is difficult to drain; so the top and bottom of the weld is the most vulnerable to corrosion. It can be seen that the welded manufacturing process of the Brazed Radiator of the steel pipe has resulted in many solder joints and long welds. In order to prevent the corrosion of the Brazed Radiator leakage, manufacturers have studied various remedial measures, such as in the pipe Brazed Radiator inside the use of a variety of paint corrosion, in the Brazed Radiator in the magnesium bar to protect the anti-corrosion, etc. Can not fundamentally solve the problem of corrosion and leakage. So that the original can be anti-corrosion Brazed Radiator into a passive anti-corrosion.
