How to classify air conditioning aluminum foil?
5.hydrophobic aluminum foil
Hydrophobic aluminum foil, aluminum foil, also known repellency, surface properties and hydrophilic aluminum foil opposite. That is when the condensed water to condense the aluminum foil surface of the foil into the contact angle larger, general at 75. the above. The greater the angle, the better the water repellency. Using the same ultimate goal of hydrophobic and hydrophilic aluminum foil, that no condensate remains in the heat exchanger between the sheets. Except that, hydrophobic foil is through increasing the contact angle of the condensate and heat transfer sheet, the condensed water is easy to slip off the water bead is formed between the heat transfer sheet to achieve the removal of condensed water purposes.
3 rrosion-resistant aluminum foil
Corrosion-resistant aluminum foil surface of the product has a certain anti-corrosion protection layer, air-conditioning heat sheet made with this product are applicable to more serious areas, and significantly improve the life of air conditioning. At the same time due to the heat transfer sheet to improve the corrosion resistance, greatly reducing the generation of surface corrosion powder, thereby improving the quality of ventilation, air-conditioned indoor air purification.
2 ating aluminum foil
The so-called coating of uncoated aluminum foil is then subjected to a surface treatment, it has some special features. In the technology development in Japan, Germany and other countries with faster, use aluminum foil coating has more than 15 years of history.
According to the coating surface of aluminum foil with the characteristics, and can be classified as follows:
1.uncoated aluminum foil
It means a non-coated aluminum foil is rolled annealed aluminum foil surface has not been treated in any form. In our country 10 years ago, about 15 years ago, foreign aluminum foil used in air conditioning heat exchangers are non-coated aluminum sheet.
