Sharaxaada Alaabta
Noocyada aluminiumka ah ee aluminiumka ah, nadiifinta dusha sare ee aluminium profiles waa tignoolajiyada wax ka qabashada ee muhiimka ah ee farsamaynta aluminiumka, taas oo hagaajin karta cimri dhererka iyo quruxda alaabta profile aluminium, taas oo kordhinaysa qiimaha iyo soo jiidashada alaabta profile aluminium.
Nadiifinta kiimikooyinka iyo dhalaalka kiimikaad ee korantada waa hab dhammaystiran oo horumarsan oo ka saari kara caariyaysiga yar yar iyo xagashada dusha alaabta aluminium;Labaduba waxay sidoo kale ka saari karaan xadhkaha isjiidka, lakabyada kuleyl ahaan qallafsan iyo anodizing kuwaas oo ku samaysan kara lakabka filimaanta farsamada.Ka dib dhalaalid kiimiko ama kiimiko kiimiko ah, dusha qallafsan ee aluminium workpieces waxay u egtahay inay noqdaan kuwo siman oo dhalaalaya sida muraayadda, taas oo hagaajinaysa saameynta qurxinta ee alaabta aluminium (sida sifooyinka milicsiga, dhalaalka, iwm.).Waxa kale oo ay ku siin kartaa alaab qiimo sare leh oo ganacsi ah si loo daboolo baahida alaabooyinka aluminiumka leh oo leh meelo dhalaalaya.Sidaa darteed, nadiifinta kiimikaad ama daawaynta korantada kiimikada ayaa loo baahan yahay si loo gaaro shuruudaha dusha gaarka ah ee siman, lebbiska iyo dhalaalaya.
Naaxinta kiimikaad iyo polishing electrochemical waxay ka dhigi kartaa dusha sare ee aluminium profiles mid aad u iftiimaya, laakiin marka la eego polishing, kiimikaad polishing (ama dhalaalaynta korantada) ayaa asal ahaan ka duwan dhalaalaynta farsamada:
Daahfurka makaanikada waa isticmaalka qalabka jireed si balaastiig ahaan loogu hagaajiyo dusha aluminiumka iyada oo loo marayo goynta xawaaraha sare leh iyo shiididda, ku qasbeysa qaybaha convex ee dusha sare si ay u buuxiyaan qaybaha concave, taas oo yaraynaysa oo simay qallafsanaanta dusha sare ee profile aluminium.Si kastaba ha ahaatee, dhalaalidda makaanikada waxay dhaawici kartaa crystallization birta, iyo xitaa waxay dhalisaa lakabyo qallafsan oo balaastik ah iyo isbeddelo qaab-dhismeed yar oo ay sabab u tahay kuleyliyaha maxalliga ah.
Naaxinta kiimikadu waa nooc ka mid ah daxalka kiimikaad ee xaaladaha gaarka ah.Nidaamku waa in la xakameeyo kala-soocidda xulashada, si qaybta convex ee dusha sare ee aluminium profile ay kala diraan ka hor aagga concave, iyo ugu dambeyntii dusha sare waa siman oo dhalaalaya.
Habka polishing electrochemical, oo sidoo kale loo yaqaan electropolishing, waxay la mid tahay polishing kiimikaad taas oo ka dhigi karta sagxadaha siman oo dhalaalaya iyadoo la xakameynayo kala dirida xulashada.Marka loo eego mabda'a dheecaanka caarada korantada, aluminium aluminiumku wuxuu ku dhex jiraa electrolyte-ka diyaarsan sida anode, iyo walxaha daxalka u adkaysta ee leh dabeecad wanaagsan ayaa lagu dhex geliyaa cathode.
In wax soo saarka warshadaha, ujeedada ugu weyn ee polishing kiimikada ama korantada polishing waa in la beddelo polishing farsamada si aad u hesho dusha siman oo dhalaalaya.Midda labaad waa in la isticmaalo dhalaalid kiimiko ama dhalaal kiimiko kiimiko ah si loo helo muuqaal aad u sarreeya oo cajiib ah qaybaha aluminium iyo aluminium.
