Weak current College】 【how to pick the radiator; buy heatsink there 6 mistakes.

Myth 1: copper radiator (or aluminum radiator) no 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 accompanied by carbonization can cause corrosion of copper radiator. In addition, because the material corrosion principles, although aluminum radiator corrosion and oxidation resistance ability strong, but vulnerable alkali corrosion and corrosion of chloride ions, so when a heating system water is alkaline (PH values higher than 8), or high chloride content (salinity), radiator corrosion leakage vulnerability exists.

Myth 2: heating water leakage is heatsink problem

During the heating season, there are several radiator leak accident was media exposure, this also caused the Chinese construction metal structure Association heating radiator Committee attaches great importance to and actively make a response: the Association's ethics, Golden Tiger, Florence, Ritter cell and other brand owners of enterprises of the heatsink on the life of the "heat sink and system problems", and find out some of the heat sink leaking "disease". The experts believe, heating water complex or radiator mixed loading problems, installation issues that may cause heating radiator heat leakage or not. Furthermore, in non-heating radiator heating season, should be maintained, otherwise the water will easily buried under threat. "In non-heating season the heating system of water emptying, leading steel radiators, boilers, water pumps and valves for corrosive rapidly, can also lead to the heat sink temperature control valve, the hot sheet, etc. "An expert in this analysis.

Myth 3: product thickness (or no welds or smooth inner wall) 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 resolve steel radiator corrosion problems, this is wrong. Because steel radiator corrosion are localized corrosion holes, not even corrosion. If according to their theory, if 1.3mm plate 3-year corrosion perforation, then surely the plate 2.0mm will corrosion perforation within five years, the same is far from satisfying users ' requirements for radiator life.

In addition, there are some of the heat sink on the market, 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 play a role. Because steel radiator corrosion does not occur in welds, this is due to corrosion of steel radiator is oxygen corrosion, so "no welds or cavities smooth does not mean that there would be no corrosion".

Myth 4: internal corrosion protection coating is equal to

In radiator market, sales statements will be called "antiseptic". In fact, far domestic radiator market common corrosion protection coating inside are two types: "organic coating" and "inorganic coating". In General, inorganic coating cost higher than organic coating process more complex technological requirements are more stringent, antiseptic effect or in the organic coating. Of course the market there are two kinds of technology are combined in one, such as Beijing de production of Sen de unlimited second-generation anticorrosion products, inorganic layers of coupled with a layer of organic layer, double layer, multiple protection, safer.

Myth 5: product more fancy weird Vietnam with decorative

Styling unique heatsink although increased decorative, satisfying people's individual requirements, but too much fancy weird and not beautiful. For example, the market flooded with "vase" "Violin", "Moon" form of the heat sink, even crudely, in the bedroom also difficult and other furniture harmonious mix, there are numerous and excessive bending of pipes will obviously influence its thermal dissipation.

Myth 6: where to buy brand-name products are the same

Consumers purchase heating and accessories at the best selection of powerful corporations, brand-name products, purchased should be chosen in a large building materials supermarket and formal brand stores. Not just for the sake of cheap, easy, convenient or figure in the community, street shop or buy private hands. According to multiple manufacturers reflects data show that in the community in temporary point-of-sale purchase radiator is the easiest problem: consumer home of radiator, reflect to manufacturers, manufacturers have found radiator brands is counterfeit or illegal distribution channels to market goods.
