Although the market is popular, but when buying DAIHATSU Brazed Radiator, it must be noted that there are more and more fake DAIHATSU Brazed Radiators in the market.
The mistake of choosing DAIHATSU Brazed Radiator is those
Myth 1, "50 years of quality assurance" does not mean "50 years of safe use". Does the "50 year warranty" of merchants mean that the quality of products is too strong? You can't believe all this. Wang said that DAIHATSU's brazing radiator itself is not easy to get problems with quality clearance, but improper installation and improper use can have many serious consequences. Some merchants say "product warranty 50 years" is in the exchange of concepts, it is said that the quality of the product itself can guarantee 50 years, but let consumers mistake for safe use 50 years and so on. Experts suggest that consumers should not be completely convinced of these claims.
Myth number two; The water pressure is the basic requirement, that the pressure ability that the businessman publicize can reach 1.2 Mpa how to treat? According to wang, working pressure of 1.2 Mpa is the most basic requirement of the DAIHATSU Brazed Radiator, which can meet the water pressure of all the communities. Consumers don't have to worry about this promotion.
Myth 3: "as long as the thick is not afraid of erosion"? Cast-iron DAIHATSU Brazed Radiator is not easy to corrode because cast iron itself can resist oxidation corrosion, not because of wall thickness. In recent years, some small manufacturers in China have tried to solve the problem of anti-corrosion of steel DAIHATSU Brazed Radiators by enlarging the wall thickness, which is incorrect, so the publicity can mislead the people. Because DAIHATSU brazing steel radiator corrosion holes are for local corrosion, rather than the uniform corrosion - if their theory, if the 1.3 mm steel corrosion perforation 3 years, then 2.0 mm steel plate is definitely will be in five years corrosion perforation, also far cannot satisfy the user requirements for DAIHATSU Brazed Radiator life.
Myth number four; "The DAIHATSU Brazed Radiator of copper material will never corrode". In general, copper is more resistant to oxidation and corrosion than steel, so it is safe to choose. But it does not rule out the possibility of corrosion in certain circumstances. Responsible manufacturers should also remind consumers.
Myth number five; ", tu is anticorrosive, "in recent years, in DAIHATSU Brazed Radiator market, sales staff will be called" corrosion ", but it will sell to consumers a variety of home, and to provide a variety of proof, make consumers dazzling. There are two kinds of commonly used coatings for DAIHATSU Brazed Radiator. A class of inorganic coatings, which are represented by zinc base chromium salts, and some manufacturers have been dealt with by shot blasting. DAIHATSU Brazed Radiators have no rust and dirt in the inner cavity, ensuring the quality of the coating. The coating and substrate are chemically bonded under high temperature, with strong adhesion and not easy to flake. However, the process requirements are extremely strict, and the quality of the coating can be guaranteed by strict control of each process parameter. The other kind of coating is organic coating, the DAIHATSU Brazed Radiator of most domestic brands in the market is used these two kinds of organic coating. The coating is mainly used to protect the body by isolating and not contacting the base directly. However, the coating is similar to the body like glue together (physical union), the substrate surface treatment requirements are high, otherwise the coating is prone to flake off.
