Abstract
Uvedeného účelu sa dosiahne tým, že sa příslušné časti vodičov uvedú do kontaktu s chlorldom zinočnatým o teplote 300 až 500 °C, a to bud1 ponořením do taveniny, alebo nanesením vrstvy ZnClz a zohriatím na příslušná teplotu. Po nasledujúcom oplachu vodou sú vodiče připravené na pocinovanie.The above purpose is achieved by bringing the relevant parts of the conductors into contact with zinc chloride at a temperature of 300 to 500 °C, either by immersion in the melt or by applying a layer of ZnCl2 and heating to the relevant temperature. After subsequent rinsing with water, the conductors are ready for tinning.
Description
Vynález sa týká spósobu odstránenía izolačného laku z vodičov, například vývodov cievok, vinutí transformátorov.BACKGROUND OF THE INVENTION The invention relates to a method for removing insulating varnish from conductors, for example coil outlets, windings of transformers.
Doteraz známe spósoby odstránenia izolačného laku:So far known methods of removing the varnish:
Mechanické odstránenie ostrým nástrojom je prácne, vodiče sú mechanicky namáhané, často poškodené. Při opalovaní laku v plameni tenké vodiče zhoria, odlakovanie přípravkami na báze organických rozpúšťadiel je náročné na dokonalé striekanie rozmáčeného laku. Uvedené nevýhody odstraňuje vynález, ktorého podstata spočívá v tom, že sa příslušná časť vodiča uvedie do kontaktu s chloridom zirtočnatým v teplote 300 až 500 °C a po rozklade laku sa povrch vodiča opláchne vodou. Výhodou odtzolovania chloridom zinočnatým, je, že prebehne dokonale behem 3 až 20 sekúnd podlá priemeru vodiča a druhu laku v uvedenom teplotnom rozsahu, přitom nezhoršuje mechanické vlastnosti médi. Metóda je vhodná pre súčasné odizolovanie vodičov s róznym priemerom a druhom laku, aj s priemerom menším ako 0,15 mm. Odsmaltovaná časť po opláchnutí vodou je kovovo čistá, kvalitně sa dá pocínovatMechanical removal with a sharp tool is laborious, the wires are mechanically stressed, often damaged. When tanning a paint in a flame, thin wires burn down, and the organic solvent-based varnishes are difficult to spray spraying paint. The aforementioned disadvantages are solved by the invention, the principle of which is that the respective conductor part is brought into contact with zirconium chloride at a temperature of 300 to 500 ° C and the conductor surface is rinsed with water after the lacquer decomposition. The advantage of zinc chloride stripping is that it runs perfectly within 3 to 20 seconds, depending on the diameter of the wire and the type of varnish in the temperature range, without compromising the mechanical properties of the medium. The method is suitable for the simultaneous stripping of conductors with a different diameter and varnish, even with a diameter of less than 0.15 mm. After the water rinsing, the smeared part is metal-clean, can be tinned
Skúšky boli převedené tým spósobom, že sme chlorid zinočnatý roztavili v sklenenej kadičke na rýchlovariči a do taveniny sme ponořili vývody tlmiviek v dlžke 20 až 30 milimetrov. Potřebná doba ponoru je v tabulke. Po rozložení laku sme vývody oplachovali vo vodě 3 až 5 sekúnd.The tests were carried out in such a way that zinc chloride was melted in a glass beaker on a blast furnace and immersed the chokes of the chokes at 20 to 30 millimeters in length. The required dive time is in the table. After the varnish distribution, the outlets were rinsed in water for 3-5 seconds.
