Farantin aluminum ɗin da aka ƙirƙira shine kayan gini na gama gari, kuma tsarinsa ya kasu kashi uku: de-esterification, injin yashi, da wanke ruwa.Daga cikin su, wanke ruwa wani tsari ne mai mahimmanci.Don tabbatar da inganci da ingancin walda na farantin aluminum, dole ne a dauki tsauraran matakan tsaftacewa don cire maiko da fim din oxide sosai a saman farantin aluminium da welded gidajen abinci.Don haka yadda za a tsaftace farantin aluminum da aka goge?
1. Mechanical tsaftacewa: Lokacin da girman da workpiece ne babba, da samar sake zagayowar ne dogon, kuma shi ne gurbata bayan mahara yadudduka ko sinadaran tsaftacewa, inji tsaftacewa ne sau da yawa amfani.Da farko a goge saman da acetone, man fetur da sauran abubuwan da ake kashewa don cire mai, sannan a yi amfani da goshin waya na jan karfe kai tsaye ko buroshin waya mai bakin karfe mai diamita na 0.15mm ~ 0.2mm har sai hasken karfe ya fito fili.Gabaɗaya, bai dace a yi amfani da dabaran niƙa ko yashi na yau da kullun ba don yin yashi, ta yadda za a hana barbashi yashi tsayawa a saman saman ƙarfe da shiga cikin narkakkar tafki yayin aikin zanen waya don haifar da lahani kamar haɗaɗɗun slag.
Bugu da ƙari, ana iya amfani da scrapers, fayiloli, da dai sauransu don tsaftace farfajiyar da za a yi wa walda.Bayan an tsaftace kayan aiki da tsari da tsaftacewa, fim din oxide zai sake farfadowa a lokacin ajiya, musamman a cikin yanayi mai laushi, a cikin yanayin da aka gurbata da acid, alkali da sauran tururi, fim din oxide zai girma da sauri.Sabili da haka, lokacin ajiyar kayan aiki da zane na waya bayan tsaftacewa da tsaftacewa har zuwa kafin zanen waya ya kamata a taqaice gwargwadon yiwuwar.Gaba ɗaya, zanen waya ya kamata a yi a cikin sa'o'i 4 bayan tsaftacewa a cikin yanayi mai laushi.Bayan tsaftacewa, idan lokacin ajiyar ya yi tsawo (fiye da 24h), ya kamata a sake sarrafa shi.
2. Chemical tsaftacewa: sinadaran tsaftacewa yana da high dace da kuma barga ingancin.Tsarin zane na waya ya dace don tsaftace ƙananan ƙananan da kuma kayan aikin da aka samar.Akwai nau'ikan hanyar tsomawa iri biyu da hanyar gogewa.Yi amfani da acetone, man fetur, kananzir da sauran abubuwan kaushi na halitta don rage ƙasa.Yi amfani da maganin 5% ~ 10% NaOH a 40 ℃ ~ 70 ℃ don wankewa na 3min ~ 7min (lokacin aluminium mai tsafta yana ɗan tsayi kaɗan amma bai fi 20min ba), kurkura da ruwa mai gudana, sannan amfani da Pickling tare da 30% HNO3 bayani a dakin zafin jiki zuwa 60 ℃ na 1min ~ 3min, kurkura da ruwa mai gudu, bushewar iska ko ƙarancin zafi.
Abin da ke sama shine hanyar tsaftacewa na farantin aluminum da aka goge.Matakan tsaftacewa na farantin aluminum da aka goge sune mahimmanci.Bayan haka, tsarin zane zai iya zama mafi karfi kuma ingancin samfurin da aka gama zai iya zama mafi kyau.
