Description
The present invention is the technical field that belongs to the enamel manufacture method.
The aluminium flake of thickness≤0.2mm is called aluminium foil.At aluminium foil surface enamel firing last layer frit for porcelain enamel, be called aluminium-foil enamel.Manufacturing to aluminium-foil enamel, as " Chinese enamel " the 2nd phase in 1985 " development of an aluminium-foil enamel " literary composition, reach narrated in " enamel " 1984 the 6th phases " development of aluminium-foil enamel and theoretic discussion " literary composition such, only made the aluminium-foil enamel sample strip under area can be held by cabinet-type electric furnace.As above-mentioned two literary compositions are narrated, be in the mixing solutions of tertiary sodium phosphate, yellow soda ash, sodium hydroxide, industrial washing clothes powder, water glass, to carry out to the surface treatment of aluminium foil; Perhaps in the acid of forming by sodium hydroxide, tertiary sodium phosphate and sulfuric acid, alkaline purification liquid, carry out respectively.Aluminium foil surface also had adopt the heat method to carry out oil removal treatment.
In order to improve the manufacture method of aluminium-foil enamel, make area and arrive greatly and can invent automatic continuous enamelling process for entire rolls of aluminum foil as the aluminium-foil enamel of building or other finishing material.
The power of the automatic continuous enamelling process for entire rolls of aluminum foil of being invented is made up of three independent device: one for aluminium foil unreels power set, and two for aluminium foil drags power set, and three is the aluminium-foil enamel winding powerplant.Dragging power set is unreeling between power set and the winding powerplant.
The aluminium foil of whole volume is successively put and is put on display under the rotation that unreels power set drives.Put the aluminium foil that puts on display and roll the dragging who drags roller under dragging power set, respectively through service sink cleaning, clean water basin rinsing, oven dry, scan-type spraying enamel glaze slip, operation such as burn till and make aluminium-foil enamel.The aluminium-foil enamel of making is wound into the entire rolls of aluminum foil enamelware under the rotation of winding powerplant drives.
The dragging speed that aluminium foil drags power set has determined the manufacturing speed of aluminium-foil enamel.Dragging speed can be regulated as required.The rolling speed that aluminium foil unreels the speed that unreels of power set and aluminium-foil enamel winding powerplant is subjected to the control of aluminium foil tensile stress proofing unit and aluminium-foil enamel tensile stress proofing unit respectively.
The speed of unreeling of aluminium foil can be regulated automatically according to the size of aluminium foil tensile stress.When the aluminium foil dragging speed when unreeling speed, the tensile stress of aluminium foil is just big, the proofing unit that detects the aluminium foil tensile stress just starts and unreels power set, perhaps accelerates to unreel the speed that unreels of power set; When the dragging speed of aluminium foil when unreeling speed, the tensile stress of aluminium foil is just little, this proofing unit unreels power set with regard to stop, perhaps slows down the speed that unreels that unreels power set.
The rolling speed of aluminium-foil enamel winding powerplant can be regulated automatically according to the size of aluminium-foil enamel tensile stress.When the dragging speed of aluminium foil during greater than aluminium-foil enamel rolling speed, the tensile stress of aluminium-foil enamel is just little, and the proofing unit that detects the aluminium-foil enamel tensile stress just starts winding powerplant, accelerates the rolling speed of winding powerplant; When the dragging speed of aluminium foil during less than rolling speed, the tensile stress of aluminium-foil enamel is just big, and this proofing unit is with regard to the stop winding powerplant, the rolling speed of the winding powerplant that slows down.
The aluminium foil of whole volume at first enters service sink after successively being put and putting on display under the dragging that drags power, dirty things such as flush away surface oil stain.Scavenging solution in the service sink or be made up of the 936 metal cleaner polymer solution in water of 3-9% perhaps is made up of the NaOH polymer solution in water of 4-15%, perhaps by the Na of 10-20%
2CO
3Polymer solution in water is formed.
Aluminium foil after service sink cleans enters clean water basin tap water rinsing, and the pH value of the surplus water of aluminium foil surface is reached about 7.
To the aluminium foil after the rinsing, dry with thermal source.After the oven dry, with aluminium foil surface not the water breakthrough mark be as the criterion.
Aluminium foil behind the cleaning, drying is dragged enters spraying glaze slurry process.Spraying enamel glaze slip sprays with scan mode.The direction of spraying scanning, on aluminium foil surface with aluminium foil to be dragged into direction vertical.The sweep rate of spraying glaze slip is subjected to aluminium foil to be dragged into the control of speed.Aluminium foil surface after the spraying, topped layer of even glaze slip coating.
The aluminium foil of glaze slip in the spraying is dragged and enters the tunnel like firing furnace and burn till.The spatial top temperature is 550 ℃ in the tunnel firing furnace.
Aluminium-foil enamel after burning till is hauled out firing furnace by the milling roller that drags power set, and behind grinding shaping, is wound into the entire rolls of aluminum foil enamelware by winding powerplant again.
Automatic method for continuous production of the present invention is than the cabinet-type electric furnace manufacture method, and can produce that area arrives greatly can be as the aluminium-foil enamel goods of material of construction or other finishing material.Scavenging solution of the present invention is more economical and practical, and cleaning performance can adapt to the needs of making continuously; Aluminium foil unreels speed and aluminium-foil enamel rolling speed can be regulated automatically according to the tensile stress of aluminium foil and aluminium-foil enamel; The sweep rate of scanning spraying glaze slip is subjected to the control of aluminium foil dragging speed, thereby successive is made automatically.
The best mode of automatic continuous enamelling process for entire rolls of aluminum foil is:
Selecting fabric width for use is 0.6 meter entire rolls of aluminum foil.It is 0.004～0.025 meter per second to the dragging speed of aluminium foil that aluminium foil drags power set.Dragging power set rolls the outside surface that drags roller and adopts heat-resistant antifriction to decrease rubber to make.Be provided with the position tumbler switch with a garden dish of milling roller rotation synchronously, when rotateing in place, switch can regularly send setting pulse by the time of adjusting in advance, and the control electromagnetism-gas-driving valve is finished once spraying scanning.The spraying sweep rate is adjusted between 0.5～0.2 time/second.
Aluminium foil tensile stress proofing unit and aluminium-foil enamel tensile stress proofing unit be by gravity-roller, active supporting arm, and composition such as upper and lower limit bit switch.Be connected the gravity-roller on the active supporting arm, because self gravitation is pressed on the aluminium foil in dragging, the aluminium foil in dragging is being supported gravity-roller owing to dragging the tensile stress that forms.When the dragging speed of aluminium foil when unreeling speed, the tensile stress of aluminium foil can be increasing, the gravity that overcomes gravity-roller because of tensile stress raises the gravity-roller position gradually, when it is elevated to the upper limit position of setting, movable arms can be touched upper limit position switch, upper limit position switch just starts the motor that unreels power set, to accelerate the speed that unreels.When aluminium foil unreels speed greater than dragging speed, the tensile stress of aluminium foil can be more and more littler, because of gravity-roller gravity overcomes tensile stress the gravity-roller position is reduced gradually, when it is reduced to the lower position of setting, movable arms can be touched lower position switch, lower position switch just turn-offs the motor that unreels power set, with the speed of unreeling that slows down.Like this, the speed that unreels of aluminium foil and dragging speed will be coordinated.
Aluminium-foil enamel tensile stress proofing unit is identical with effect with the structure of aluminium foil tensile stress proofing unit, its difference is that the upper limit position switch of aluminium-foil enamel tensile stress proofing unit plays a part to turn-off the winding powerplant motor, and lower position switch works to start the winding powerplant motor.Thereby the rolling speed of aluminium-foil enamel and the dragging speed of aluminium foil are coordinated.
936 metal cleaner polymer solution in water of the scavenging solution the most handy 3～9% of service sink.The temperature of scavenging solution remains between 50～85 ℃.Scavenging period is 1～3 minute.
Long 6 meters of tunnel like electric firing furnace.The top temperature of central section is controlled at 550 ℃ ± 10 ℃, and temperature in is controlled at 40 ℃, and temperature out is controlled at 100 ℃.
