What are the radiator materials?
1. Cast iron radiator
Advantages: it can be used in any water quality and external environment, with good corrosion resistance, long service life and affordable price.
Disadvantages: low thermal efficiency, high energy consumption, easy pollution and unsightly appearance.
Cast iron radiator has poor comprehensive performance and is not environmentally friendly. Although the price is relatively close to the people, it is already an outdated product.
2. Steel radiator
Advantages: strong compression resistance, high thermal efficiency, low carbon and energy saving, beautiful appearance, convenient installation and maintenance, and moderate cost performance.
Disadvantages: it does not have antiseptic effect and is easy to oxidize. Therefore, some manufacturers have upgraded the anti-corrosion technology of radiators-anti-corrosion King Kong products. It is a subversive steel radiator, with steel cost performance and corrosion resistance much higher than that of ordinary steel radiators. Anti-corrosion diamond radiator adopts special magnesium-aluminum alloy installed at the bottom of steel radiator, and the active magnesium-aluminum alloy reacts with ions in water first to avoid "under-scale corrosion" and "bottom metal corrosion". The consumption time of a magnesium-aluminum alloy is more than 15 years, which greatly prolongs the life of the radiator, does not need full water maintenance, and the warranty period is 15 years.
3. Copper-aluminum composite radiator
Aluminum wings with good heat dissipation effect are attached to the copper tube with anti-oxidation corrosion, so that water will not corrode when flowing in the copper tube, and heat can be fully volatilized from the aluminum wings, which can be described as a strong combination of materials. Its advantages are corrosion resistance, large heat dissipation, fast heat dissipation, lighter and more beautiful than steel. Although some corrosion problems can be solved, the disadvantages are very obvious, because different materials have different thermal expansion coefficients, cracks will even become loose after use, and cracks will produce thermal resistance, which not only greatly affects heat conduction and reduces heat dissipation effect, but also reduces heat dissipation year by year. Looseness will not only affect the appearance, but also produce vibration and noise.
4. Aluminum radiator
There are mainly two kinds of welding: high pressure welding and stretching aluminum alloy welding, which have the advantages of high thermal efficiency, rapid temperature rise, beautiful appearance, energy saving and material saving. With the outstanding requirements for decoration, controllability and economy of radiator, it has developed rapidly in recent years.
5. Pure copper radiator
Advantages: good thermal conductivity and high corrosion resistance.
Disadvantages: the price is relatively high and the style is single.
Compared with other materials, pure copper radiator has outstanding thermal conductivity and corrosion resistance, but the high price still makes many consumers flinch. Low cost performance leads to extremely low market share.
When consumers choose a suitable radiator for themselves, they should first consider the heating mode of the family. There are two principles:
1. central heating series: it is suitable for selecting steel column radiators, which have good heat dissipation and pressure resistance and can withstand greater pressure, because the water pressure of central heating is higher than that of self-heating.
2. Wall-hung boiler heating series: copper-aluminum composite radiator is adopted, which is small in size and low in water quality requirements, and has higher heat dissipation efficiency than steel radiator.
When choosing a radiator, we should first investigate the heating environment in this area, and then decide the material of the radiator according to the heating demand at home and personal preference. For example, the hot water quality in this area contains a lot of oxygen, so it is not suitable to use steel radiators, otherwise it will be easily oxidized and corroded, and the probability of leakage is high. If the heating system at home is independent heating, you can use copper-aluminum composite radiator or anti-corrosion king kong, because this radiator has a large heat dissipation, which can quickly heat the room in a short time, effectively saving resources and being beneficial to environmental protection.
Judging from the current market situation, the mainstream radiators are mainly steel radiators and copper-aluminum composite radiators. The utility model has good heat dissipation effect, beautiful appearance and reasonable price. The copper-aluminum composite radiator has the advantages of good thermal conductivity, beautiful appearance, space saving and good matching home decoration effect. Cast iron radiator is no longer advocated, and copper and plastic aluminum are no longer widely used.
There is a lot of knowledge and technology in choosing radiators. Materials suitable for your family need to be considered. Gold Flagship Reminder: Because there are many radiator brands in the market, it is difficult for consumers to distinguish good from bad except for simple appearance judgment. Brother Jin Flagship suggested that friends try to choose big brands or go to large building materials stores, so as to get more protection.
Many people buy radiators because they want to be cheap. When they choose to buy radiators, they always hear many people say, pointing to radiators, they say how good radiators are and how easy they are to use, but they don't say shortcomings. You can't just look at the price when buying radiators. After all, wearing thousands of clothes is for consumption, not for your own use. Health and warmth are the most important things.
The first kind of rough radiator is not random.
The radiator can be used for twenty or thirty years once it is used. Pay attention to the safety and quality of use, and be strict with every detail of production. If the radiator technology is rough, such as uneven radiator interface, acne will appear in the welding area. This kind of defective product is used for normal heating in the home, and it is easy to leak or even burst.
The quality of the second heating product is not high and not ideal.
For example, the purchase of household appliances such as air conditioners and televisions and a certain amount of maintenance are also called warranty period. As a device that contacts hot water, radiators should pay more attention to this. Regular radiator brand products on the market will have different warranty periods based on high quality.
The quality of radiators produced by many small workshops cannot be guaranteed, and problems can only be borne by themselves.
When buying radiators, you must polish your eyes, choose carefully, and keep the quality of radiators appropriate. It is the best and expensive for a reason.
The third radiator is not lower than the market price.
Radiators, like other household products, have an average market price, such as a radiator with a height of 180 cm, and a copper-aluminum composite radiator is about 270 yuan per piece; Radiator steel approx. 180 yuan. There will be great differences in different materials, except brass radiator, copper-aluminum radiator is the most expensive.
If it seriously deviates from the market price, the radiator itself is likely to be greasy, such as renovation and long life. For the sake of health and safety, please don't choose.
The fourth radiator that does not meet the quality of domestic water is not optional.
Many people don't care about the performance of the radiator or whether it matches the situation at home. This is unreasonable. The applicability of radiator is a compulsory course.
If steel radiator is used, the heat medium of household heating system should not exceed 95℃ hot water, and the oxygen content in water should not be too high. The water quality PH value of aluminum radiator is between 5 and 8. So these knowledge points must be clear.
