The production technology and characteristics of Chalco xem da bong truc tiep fin material
Cladding xem da bong truc tiep Finstock
Production process: The cladding xem da bong truc tiep fin stock material is generally composed of a core material and a composite layer. After xem da bong truc tiep ingots - casting - soaking - compounding - hot rolling - cold rolling - slitting - It is produced by multiple processes such as packaging.
Features: complex process, high price, excellent brazing ability
Non-Cladding xem da bong truc tiep fin stock
The Non-Cladding xem da bong truc tiep fin stock includes plain xem da bong truc tiep foil and Pre-coated xem da bong truc tiep Fin Stock
The Production technology and characteristics of Plain xem da bong truc tiep foil
Production process: xem da bong truc tiep foil with no surface treatment after rolling and annealing.
Features: simple process, low price
The Production technology and characteristics of Pre-coated xem da bong truc tiep Fin Stock
Production process: coat both sides of plain foil with anti-corrosion coatings and hydrophilic coatings with various quality requirements.
Features: the heat exchange efficiency is increased by about 59%, thus playing the role of energy saving, material saving, reducing the volume of air conditioners and prolonging the service life.
Several classifications of non-cladding xem da bong truc tiep fin stock
Uncoated xem da bong truc tiep fin stock
Uncoated xem da bong truc tiep fin stock is actually the silver light plate. It is an xem da bong truc tiep foil that has been rolled and annealed without any form of surface treatment. At present, there are very few uncoated xem da bong truc tiep foils used for air conditioners, accounting for less than 50%. While 15 years ago, uncoated xem da bong truc tiep foils were the mainstream.
Pre-coated xem da bong truc tiep fin stock
Coated foil surfaces have been treated to provide more functionality than non-coated ones. Many countries began to use coated xem da bong truc tiep foil in the last 10-15 years. Many of the corrosion-resistant xem da bong truc tiep foils and hydrophilic xem da bong truc tiep foils mentioned in the following content can be classified as coated xem da bong truc tiep foils.
Corrosion resistant xem da bong truc tiep fin stock
As the name suggests, corrosion-resistant xem da bong truc tiep fin stock is coated with a corrosion-resistant protective layer. Corrosion-resistant xem da bong truc tiep foil can not only be used in harsh environments, improve the service life of air conditioners, but also help improve the ventilation quality of air conditioners. So, it is widely used.
Hydrophilic xem da bong truc tiep fin stock
The surface of hydrophilic xem da bong truc tiep Fin Stock foil has strong hydrophilicity and certain corrosion resistance. Its main function is hydrophobicity, which avoids the effect of water droplets "bridge" between the heat exchange fins and affects the ventilation effect of the heat exchanger. In this way, it can improve the heat exchange rate of the air conditioner and save electricity under the same cooling capacity. In the past, the general hydrophilic xem da bong truc tiep foil on the market not only has good hydrophilicity on the surface, but also has high corrosion resistance, so that the performance of the air conditioner is more optimized.Quick Quote
Hydrophobic xem da bong truc tiep fin stock
Hydrophobic xem da bong truc tiep fin stock foil is also called hydrophobic xem da bong truc tiep foil. Its surface properties are the opposite of hydrophilic xem da bong truc tiep foil, but its ultimate goal is also to prevent condensed water from remaining between the heat exchange fins. The difference is that the hydrophobic xem da bong truc tiep foil achieves the purpose of removing the condensed water between the heat exchange fins by increasing the contact angle between the condensed water and the heat exchange fins, so that the condensed water forms droplets that are easy to slide off.
Self-lubricating xem da bong truc tiep fin stock foil
Self-lubricating xem da bong truc tiep fin stock foil does not need to add lubricating oil separately during its punching process, and the lubrication during punching is borne by the pre-treated film on the surface of the xem da bong truc tiep foil. Since there is no need to add lubricating oil, the subsequent cleaning and drying processes of trichloroethylene are also omitted.
Mildew-proof xem da bong truc tiep fin stock foil
Mildew-proof xem da bong truc tiep finstock foil is mainly used for the indoor unit part of the air wither. Its main function is to prevent the surface of the heat exchange fin from becoming moldy due to the use or placement for a long time, thereby improving the ventilation quality of the empty wither.
The main experimental test of Chalco xem da bong truc tiep fin stock
Alkali resistance test
Since the lubricating oil on the surface of the heat exchange fin after punching needs to be removed with an alkaline cleaning agent, it is required that the functional coating on the surface of the xem da bong truc tiep foil must have a certain alkali resistance. The experimental conditions are generally immersed in 20% NaOH solution for 3 minutes, and then take out the experimental xem da bong truc tiep foil to see if the xem da bong truc tiep foil foams.
Humidity and heat resistance test
This experiment is to test the degree of corrosion after a long time at a certain temperature and a certain humidity, so as to judge its corrosion resistance. This performance is also an important indicator to measure the weatherability of the heat exchanger fins.
Salt spray test
The purpose of the experiment is to carry out the salt spray experiment of extreme test on the corrosion resistance of the fins with professional instruments to simulate the influence of the harsh environment on the fins in reality.
Experimental conditions: The test xem da bong truc tiep foil was placed in a salt water spray environment of 35 °C and 3%.
Experimental basis: "GB/T10125-2012-Artificial Atmosphere Corrosion Test-Salt Spray Test". General outdoor environmental materials require resistance to neutral salt spray for 500h.
Experimental requirements: No corrosion spots are required for 500h, because the resistance to salt spray corrosion is directly related to the service life of the heat exchange fins.
The application of xem da bong truc tiep fin material
The xem da bong truc tiep fin material is punched and flanged by a punching machine to become a heat dissipation fin. A heat exchanger is formed after tube threaded, tube expanded, degreased, and assembled. Cladding xem da bong truc tiep fin stock is mainly used in automotive parallel flow condensers.
Non-composite xem da bong truc tiep fin materials are mainly used in automotive radiators, intercoolers, oil coolers, evaporators, water tanks, heaters, and various air conditioner radiators, etc.
