Said invention possesses the advantages of simple equipment and process, small water consumption, no pollution, high coating utilization and good coating quality, etc.
Description
A kind of aluminium alloy section surface coating process and special equipment, belong to the external coating technical field, be mainly used in the application aluminium alloy section surface, also can be used for the external coating of steel and other metal foldings, hollow section, plastic material and metal tube, multiple tube etc.
In the prior art, the method of traditional aluminium alloy section surface application is: will many (or part) aluminium alloy extrusions in a row be lifted on the suspender after the binding, and then they be put into a very big tank and concentrate and soak, carry out chemical treatment, water cleaning or spray, drying with soda acid etc. and remove and concentrate spraying behind the moisture content of being stained with on the surface again and with the concentrated baking and curing of large-scale drying tunnel.The required operation site area of this conventional method is big, the building object height, and equipment investment is big, and water is many, and environment is had pollution, and the sewage disposal difficulty is big, the expense height, utilization efficiency of coatings is the highest by only 75%, waste coating and need carry out exhaust-gas treatment, thereby painting cost is big.
The object of the present invention is to provide a kind of building, equipment investment few, required place is little, technology is simple, the surface pre-process has been abandoned traditional method of chemical treatment, thereby do not produce the waste water that acid, alkali and passivator cause, free from environmental pollution, water consumption is little and can recycle and reuse, single (or part) spraying, adopt a plurality of static mini sprinklers that section bar is formed the envelope application, utilization efficiency of coatings can significantly reduce toxic emission up to more than 95%, spraying is even, aluminium alloy section surface coating process and special equipment that coating quality is good.
According to the structure of external coating basic principle and section bar and the characteristics of static mini sprinkler, at existing questions in the prior art, basic design of the present invention is: changing chemical pre-process is the mechanical type pre-process, changing single rifle concentrates spraying in batch to be the spraying of envelop-type single-piece, be about to treat single (or part) aluminium alloy extrusions of application, by the elevator tool pack into set up on the skyborne single track slideway and make its can be as required under the control of electric controller up and down or move left and right, the mechanical type pre-procesor that employing is made up of a plurality of roll-type polishing wheels carries out multistage polishing (also can adopt sandblast), carry out spray Cleaning for High Capacity then, make the surface of the work cleaning and form evenly trickle texturing surface, after hot blast drying and preheating, promptly carry out the envelop-type spraying again, send in the drying tunnel and be finished product after the baking and curing with the static mini sprinkler.
Aluminium alloy section surface coating process of the present invention, it is characterized in that this method comprises following process steps: (1) is treated with single-piece that the application workpiece lifts on the slideway by the elevator tool and starts electric controller and is adjusted workpiece position up and down, (2) carry out the mechanical surface pre-process, (3) hot blast drying and preheating, (4) carry out the envelop-type spraying with the static mini sprinkler, (5) send into baking and curing in the drying tunnel.
Above-mentioned mechanical surface pre-process comprises the polishing wheel polishing of a～f (deciding on the section material section complexity, the amount doesn't matter) level roll-type and water spray Cleaning for High Capacity or blasting treatment and two steps of water spray Cleaning for High Capacity.
Aluminum alloy surface application special equipment of the present invention, it is characterized in that this special equipment by be loaded on aerial single track slideway 3, an end connect above-mentioned single track slideway 3 and can along its move left and right and the flexible up and down other end clamp single-piece treat application workpiece 1 elevator tool 2 and according to operation arrange from front to back be loaded on ground surface of the work pre-process mechanism 4, dry up preheating mechanism 5, spray booth 6, drying tunnel 7 and device that interior dress static mini sprinkler carries out the envelop-type spraying constitute at complete equipment electric controller 8 nearby.
Above-mentioned mechanical work piece surface pre-process mechanism 4 is made of a～f level roll-type polishing wheel and spray tank g.
Above-mentioned mechanical work piece surface pre-process mechanism also can be made of sand-blasting machine and spray tank g.
Advantage of the present invention is: technology is simple, required area of mill site is few, highly there is not specific (special) requirements, equipment investment is few, under the workpiece prerequisite of application equal number, comparing with conventional method is 1/10th of conventional method equipment investment only, and site area only is 1/5th, because pre-process changes mechanical type into by chemical method, so can economize on water in a large number and recyclable utilization, non-environmental-pollution, not only surface of the work is clean, and can form evenly that trickle texturing surface is beneficial to the coating set, add that changing single rifle concentrates spraying for the spraying of static mini sprinkler envelop-type in batch, not only reduced the coating spatter loss, utilization rate brings up to 95% by 75%, saved coating, alleviated air pollution, and coating quality is better, coating curing is contracted to 1～2 minute by dozens of minutes, improved work efficiency, thereby painting cost can reduce greatly.
Accompanying drawing is one of most preferred embodiment of the present invention equipment configuration schematic diagram.
In conjunction with the accompanying drawings and most preferred embodiment, the architectural feature of special equipment of the present invention and the method step of this equipment application aluminium alloy extrusions of use are described below: long 40 meters left and right sides single track slideways 3 of I-shaped steel of installing on the house beam of workshop, small-sized locomotive is housed on it, the clamped single-piece that this dolly and its lower end bind is treated the common elevator tool of forming 2 of steel wire rope of the clamp of application workpiece 1, according to technology nylon folder stainless steel wire diameter successively being housed successively on ground below the slideway 3 is the surface of the work pre-process mechanism 4 that a that can the adapt to various difform section bar needs～f level polishing machine formed of 150mm left and right sides roll-type polishing wheel and water spray system g are formed, dry up preheating mechanism 5 by what the hot bellows that air blast is housed in it was formed, the drying tunnel 7 that can carry out long 12 meters of the spray booth 6 of envelop-type spraying and low-voltage and high-current directly-heated type along three static mini sprinklers of garden Zhou Junbu is housed in it, PC industry electric controller 8 also is housed near the ground each above-mentioned parts.
To handle aluminium alloy door's window profile is example, its processing step is: pack single-piece aluminum alloy doors and windows section bar workpiece 1 in the clamp of card suspender 2 (1), starting electric controller 8 adjusts height earlier and controls dolly later on again and move along slideway 3, (2) workpiece 1 is introduced into the operating room that polishing machine and spray tank are housed with about 10 meters/minutes speed and carries out the mechanical surface pre-process, make the clean and even trickle texturing surface of formation of surface of the work, (3) control workpiece 1 moves on, entering the hot blast drying chamber removes branch that surface of the work gets wet and makes its preheating, (4) move on again and carry out envelop-type spraying into spray booth, (5) after workpiece 1 is admitted to and connects power supply automatically by controller 8 controls earlier in the drying tunnel 7, heating power limit, limit is solidified and is advanced, and comes out to get product in about one minute in drying tunnel.
