Second method is an immersion oil lacquer method, and its main production is: aluminium bar (or copper bar) → wire drawing (or extruding) becomes the immersion oil lacquer → repeated drying curing → finished product of bare wire → pre-treatment (or oil removing) → cleaning → oven dry → repeatedly.
Wherein, the disadvantage of first method is to use a large amount of concentrated sulfuric acids in the process of making oxide-film, and the sublimed sulfur acid vapor not only causes heavy corrosion and pollution to environment aborning, and the human respiratory tract caused serious injury, the sewage of discharging pollutes water quality; The speed of Chu Liing is slow in addition, and labor productivity is also relatively lower.The disadvantage of second method is that the content of organic solvent in the paint that uses is up to 60%-70%, in coating process, all be discharged in the atmosphere and go, not only cause the pollution of atmosphere, also cause a large amount of wastes of resource, the requirement that does not meet national environmental protection and economize on resources, its poisonous organic solvent also brings harm to operating personnel's health, and organic solvent also exists potential hidden danger as inflammable and explosive product to safety in production simultaneously.
In order to overcome the shortcoming of above-mentioned two kinds of finishings, high-pressure electrostatic powder coating process and corresponding powdery paints have been developed, though but this finishing can not cause the pollution to environment, but because the electric field shielding effect causes the coating thickness difference between the plain conductor of application side by side bigger, inhomogeneous, filming occurs particle easily, and baking-curing speed is slow.
Summary of the invention
In view of this, main purpose of the present invention, be to provide a kind of environmental protection, safety, coating thickness evenly, the electromagnetic wire manufacture method of no particle and pin hole.
According to above-mentioned purpose, the invention provides a kind of manufacture method of electromagnetic wire, mainly comprise following steps: will clean through the metal wire of pre-treatment, dry, film, baking-curing becomes electromagnetic wire, wherein, the described step of filming adopts frictional electrification charged powders finishing coating metal line.
As preferably, described baking-curing step adopts infrared ray cured technical cure to film.
As preferably, the class coating material that adopts in the described frictional electrification charged powders finishing can be high molecular polymerization powdery paints or polyester powder coating or polyurethane powder coating respectively.
As preferably, the work condition environment that described employing high molecular polymerization powdery paints is toasted is 200 ℃/2～4min.
As preferably, the work condition environment that described employing polyester powder coating is toasted is 200 ℃/2～4min.
As preferably, the work condition environment that described employing polyurethane powder coating is toasted is 200 ℃/3～6min.
As above-mentioned technical scheme as can be known, the manufacture method of electromagnetic wire of the present invention can not brought harm to environment, and owing to adopt the triboelectric charge spraying process can make powdery paints coating thickness on metal wire more even, and can not produce particle, simultaneously owing to adopt infrared ray cured technology, thereby begin intensification heat transfer melted powder coating outward by metal wire inside, helping air and the micromolecular compound of powder in filming discharges before film forming, help improving electrical insulation capability and the appearance of film and the levelling of filming, avoid producing pin hole, and curing rate is fast, enhance productivity greatly, and energy savings.
