Jauhemaalaus on prosessi, jossa kuivaa jauhemaalia (joko kestomuovista tai kestokovettuneesta polymeerist\u00e4) levitet\u00e4\u00e4n metallipinnalle s\u00e4hk\u00f6staattisesti. Toisin kuin perinteinen nestem\u00e4inen maali, jauhemaalaus ei tarvitse liuotinta pit\u00e4m\u00e4\u00e4n maalin sideainetta ja t\u00e4yteainetta nestem\u00e4isen\u00e4 suspensiona. T\u00e4m\u00e4 mahdollistaa paksumpien maalien levitt\u00e4misen ilman valumista tai notkistumista, ja maalit ovat sen ansiosta my\u00f6s sitke\u00e4mpi\u00e4.<\/p>

Jauhemaalausprosessi aloitetaan maalattavan osan s\u00e4hk\u00f6isell\u00e4 maadoituksella, joka antaa sille negatiivisen nettovarauksen. Maadoituksen j\u00e4lkeen maali ruiskutetaan kappaleeseen koronapistoolilla, joka antaa jauheelle positiivisen varauksen. N\u00e4iden kahden komponentin polarisaatio saa jauheen tarttumaan metalliin, jossa se pysyy niin kauan kuin sit\u00e4 ei h\u00e4irit\u00e4.<\/p>

Kun jauhe on saavuttanut tietyn paksuuden kappaleessa, se kovetetaan polymeerikalvoksi korkeissa l\u00e4mp\u00f6tiloissa (~200 \u00b0C), esimerkiksi konvektiouunissa. L\u00e4mp\u00f6kovettuvat polymeerit ristisilloittuvat kovettumisprosessin aikana parantaakseen suorituskyky\u00e4, mutta l\u00e4mp\u00f6muoviset lajikkeet yksinkertaisesti virtaavat kuumennettaessa muodostaen lopullisen pinnoitteen.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
