Radiator buy learning more beware stockjobber reduce heating quality

With the heatsink competition heating up, some enterprises publicity methods are beginning to misinform, various "new concept" endless, dazzling consumers.

Myth one: "copper radiator never corrosion"

In General, copper than steel corrosion resistance is better, but in certain circumstances, copper radiator has corrosion, for example, the system if the sulphur content of sludge, excessive, or selection of copper surface with carbon, etc. will cause corrosion of copper radiator.

Myth 2: "the wall thickness is not afraid of corrosion"

Cast iron radiator corrosion damage, not because the iron itself antioxidant corrosion performance is good, but not because of the wall thickness. In recent years, some small manufacturers seek to increase the thickness to address corrosion protection of steel radiator, some experts pointed out that, regardless of the corrosion and wall thickness. Because steel radiator corrosion are localized corrosion holes, not even corrosion.

Myth 3: "aluminum radiator does not corrode"

Aluminum radiator does not fear the acid corrosion, but prone to alkali corrosion and corrosion of chloride ions, so when a heating system water is alkaline (pH above 7), or high chloride content (salinity), radiator corrosion leakage vulnerability exists.

And because of the aluminum alloy welding performance difference, it is recommended that internal users should avoid using belt weld aluminum heatsink, and buy the whole die-casting aluminum alloy radiator in order to avoid leaks caused by welding, loss of property.

In addition to remind consumers: aluminum alloy radiator water quality requirements and steel, so should avoid aluminum alloy radiator mixed with other materials.

Myth 4: "no welds or smooth inner wall fear corrosion"

Current market some radiator manufacturers in the publicity of its radiator products "no welds, cavity clean smooth" and so on — in fact, this is the radiator corrosion-resistant and does not work! because steel radiator corrosion does not occur in welds, it is composed of steel radiator corrosion principle oxygen corrosion decided, "no welds or cavities smooth does not mean that there would be no corrosion".

Myth 5: "the inner coating is antiseptic"

Heatsink for internal coating of paint can be classified into two categories. A class for inorganic zinc chromate coatings to class as representative, on behalf of the enterprise is Jensen's "unlimited" anticorrosive Emerson de radiator. Another type of coatings for organic coating, the current market the majority of the domestic brands of radiator selection both organic coatings. There is also the majority of manufacturers in order to save costs, save some of the processing chain, only once for internal coating, General coating thickness does not exceed 30 microns. Therefore the current market many do internal coating of the radiator, dip in the hot water in 5 days or so it appears large bubbles, coating start peeling off.

Myth 6: "the insurance company underwriting 30 years"

In fact, this is a very irresponsible. On the surface, any market sales of the radiator has insurance, consumers must remember: each product of insurance is an annual insurance, if the enterprise is gone, there will be no insurance, and therefore does not exist "underwriting" of 30 years.
