Abstract
The invention relates to a part of heat exchange or heat transmission device in a field of heat exchange, in particular to a preparation method for a hydrophilic aluminum foil. The method of the invention includes the following steps: a. surface treatment of the aluminum foil: using a degreased liquor to wash the surface of the aluminum foil under a temperature of 5o to 60 DEG C, squeezing the surface of the aluminum foil by a squeezing roller, then using deionized water to wash the surface of the aluminum foil for at least twice and then detecting the aluminum foil and confirming the cleanness of the surface; b. aluminum foil drying: putting the aluminum foil into an oven, controlling the temperature in the oven at 150 to 210 DEG C and cooling naturally under a normal temperature after drying; c. coating an anti-corrosion dope on the roller: coating the anti-corrosion dope on the surface roller of the aluminum foil; d. coating a hydrophilic dope on the roller: coating the hydrophilic dope on the anti-corrosion coating layer after the anti-corrosion coating layer is dried; and drying to form a hydrophilic coating layer and manufacturing the hydrophilic aluminum foil. The method of the invention solves the problems of large machine abrasion and poor hydrophilic effect of the existing hydrophilic aluminum foil during a later stage processing.
Description
Technical field
The present invention relates to the heat exchange in heat exchange field or the parts of heat-transfer equipment, especially a kind of preparation method of hydrophilic aluminium foil.
Background technology
Hydrophilic aluminium foil be a kind of be the composite of base material with the aluminium foil, the good heat radiating that promptly has normal aluminium foil has not available corrosion resistance of normal aluminium foil and hydrophily again, is a kind of good heat sink material, is used in the radiator of air-conditioning.
There is stronger hydrophily on the hydrophilic aluminium foil surface, on air-conditioning, use, can make the moisture in the hot-air be easy to drawout and flow away suffering from the globule that condenses on the backing downwards along sheet material, can avoid the globule between heat exchanger fin to form " bridging " like this and influence the ventilation effect of heat exchanger, thereby make rate of heat exchange improve 5%, hydrophilic aluminium foil also has other advantage in addition: anticorrosion, mould proof, free from extraneous odour; Because the no globule can correspondingly reduce the air-conditioning noise that vibrations Zhao becomes, it is indoor to prevent that the air-conditioner oxide powder is blown into.
The hydrophilic aluminium foil preparation singly is coated with method by initial list baking, after develop into again that two bakings are two to be coated with, also have three bakings three to be coated with method abroad, it is to add at hydrophilic coating to be coated with one deck lubricant coating this can reduce wearing and tearing to processing equipment that certain three bakings three are coated with method, but such existence that lubricant coating is arranged influenced the hydrophily of hydrophilic aluminium foil.
Summary of the invention
The technical problem to be solved in the present invention is: there is the problem of and hydrophilic effect difference big to post-production mechanical wear in existing hydrophilic aluminium foil, the invention provides the good hydrophilic aluminium foil of a kind of hydrophilicity.
The technical solution adopted for the present invention to solve the technical problems is: have following steps:
A. aluminium foil surface is handled: clean aluminium foil surface at 50～60 ℃ with degreasant solution, extract aluminium foil surface with squeeze roll, use washed with de-ionized water aluminium foil surface at least 2 times then, detect then and confirm the aluminium foil surface cleaning;
B. aluminium foil oven dry: clean clean aluminium foil at drying in oven moisture content, temperature is controlled at 150～210 ℃, the cooling down of back normal temperature
C. roller coat corrosion-proof paint: corrosion-proof paint on the surface roller coating of aluminium foil;
D. roller coat hydrophilic coating: do solid back at underseal and on underseal, apply hydrophilic coating, and oven dry forms hydrophilic coating, make hydrophilic aluminium foil.
Degreasant solution described in a of step described in the present invention dissolves in 100 parts of deionized water and stirring with 1～3 part of degreasing agent under 50～60 ℃ of temperature even, the pH value is controlled at 10～12, pH both can reach the purpose of cleaning aluminium foil surface 10～12, also can not cause corrosion to aluminium foil simultaneously.The deionization electrical conductivity of water that uses is avoided guaranteeing the quality of hydrophilic aluminium foil to bringing mordant ion in the subsequent process into smaller or equal to 30 μ s/cm.
Detect aluminium foil described in a of step described in the present invention and adopt the moisture film observation, on aluminium foil surface, use deionized water to form film and do not break, then aluminium foil surface cleaning, then aluminium foil surface has foreign matter on the contrary, needs to clean again.
Described in the present invention in the steps d hydrophilic coating be hydrophily epoxy coating or hydrophilic acrylic resin's coating, do not contain the silicon constituents in the employed hydrophilic coating and can not cause post-production process at hydrophilic aluminium foil processing equipment heavy wear.
The invention has the beneficial effects as follows that the hydrophilic angle control of the initial stage of the hydrophilic aluminium foil that the present invention produces is less than 5 degree, the permanent hydrophilic angle has good hydrophilicity and corrosion resistance less than 15 degree.
The specific embodiment
Example one:
A. aluminium foil surface is handled: forming the pH value at 50～60 ℃ with 1Kg degreasing agent and 100Kg deionized water mixing and stirring is 10.2 degreasant solution, clean aluminium foil surface with the degreasant solution that configures, extract aluminium foil surface with squeeze roll, use the dried aluminium foil surface of deionized water cleaning agent at least 2 times again, using deionized water to form film then on aluminium foil surface does not break, then aluminium foil surface cleaning;
B. aluminium foil oven dry: clean clean aluminium foil at drying in oven moisture content, temperature is controlled at 150～210 ℃, the cooling down of back normal temperature
C. roller coat corrosion-proof paint: coating is packed in the coatings tank, and make coating keep certain backflow in groove, coating does not form precipitation, adopts to be coated with roller corrosion-proof paint on the surface roller coating of aluminium foil;
D. roller coat hydrophilic coating: do solid back at underseal and on underseal, apply hydrophilic coating, and oven dry forms hydrophilic coating, make hydrophilic aluminium foil.
