Gold coated hydrophilic aluminium foil is formed by hydrophilic remedy at the surface of plain aluminium foil. Blue hydrophilic aluminum foil is a common cloth used forhydrophilic aluminum foils, any other one is golden hydrophilic aluminum foil. The hydrophilic layer permits the water droplets condensed from moisture in the warm air to unfold without difficulty on the warmth exchanger fins and waft down along the material, for this reason warding off the bridging of water droplets between the fins and affecting the air flow effect of the warmth exchanger. This will boom the heat change fee by using 5%.
The manufacturing system of gold lined hydrophilic aluminium foil: Unrolling pretreatment floor roll coating (first roll coating first drying second roll coating 2nd drying) coiling.
The feature of pretreatment is to beautify the adhesion between the coating and aluminum foil.
The function of the coating is to increase the hydrophilicity and corrosion resistance of the product.
For aluminum foil for air conditioner with high overall performance requirements, if the primary coating cannot meet the desired requirements, a 2nd coating is needed. Commonly, unmarried coated aluminum foil merchandise have hydrophilic and corrosion resistance capabilities in a single coating. Double coated hydrophilic aluminium foil products have corrosion resistance feature inside the first coating and hydrophilic function in the 2nd coating.
Gold lined hydrophilic aluminium foil is essentially used for air conditioner warmth dissipation fins. The floor of hydrophilic aluminum foil has robust hydrophilicity. The fine of hydrophilicity is determined with the aid of the attitude fashioned whilst water adheres to the foil surface. Hydrophilic aluminum foil is usually used on air conditioner condensers. Its fundamental feature is to permit water droplets condensed from moisture in the hot air to spread effortlessly on the heat exchanger fins and flow down along the fabric. This could keep away from the bridging of water droplets between the fins and affecting the air flow impact of the heat exchanger. Therefore, it may improve the warmth exchange price of the air conditioner and save electricity below the same cooling capacity situations.
