Kufunika Kwa Pickling Acid ndi Passivation mu Surface Chithandizo cha Zitsulo Mipope

Kuyambitsa Kukokoloka kwa Acid ndi Passivation
Mapaipi achitsulo amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha kulimba kwawo, mphamvu, komanso kukana dzimbiri.Komabe, kuti awonetsetse kuti akugwira ntchito bwino komanso amakhala ndi moyo wautali, ndikofunikira kugwiritsa ntchito njira zochizira pamwamba monga zitsulo zonyamula ndi kuphatikizika.Bukuli likufuna kuwunikira kufunika kwa njirazi polimbikitsa mipope yachitsulo kuti ikhale yabwino komanso yolimba.

Gawo 1: Kodi Kutola Zitsulo ndi Chiyani?
Steel pickling ndi njira yamankhwala yomwe imaphatikizapo kuchotsa zonyansa, monga dzimbiri, sikelo, ndi ma oxides, pamwamba pa mipope yachitsulo.Cholinga chachikulu cha pickling ndikuyeretsa pamwamba pazitsulo bwino, kukonzekera chithandizo chotsatira chapamwamba monga passivation.
Panthawi ya pickling, mipope yachitsulo imamizidwa mu njira ya acidic, yomwe imakhala ndi hydrochloric kapena sulfuric acid.Asidi amakhudzidwa ndi zonyansazo, kusungunula ndi kuzichotsa pamwamba pazitsulo, ndikusiya kumaliza koyera ndi kosalala.

Gawo 2: Njira Yowotchera:
Njira yopangira pickling imaphatikizapo njira zingapo zowonetsetsa kuti zonyansa zimachotsedwa pamapaipi achitsulo:
Khwerero 1: Kuchepetsa: Musanatole, mapaipi achitsulo amachotsedwa kuti achotse mafuta, mafuta, kapena dothi lililonse lomwe lili pamwamba.Njirayi imatsimikizira kuti asidi amatha kuyanjana mwachindunji ndi zonyansa pamtunda wachitsulo.
Gawo 2: Kumizidwa kwa Acid: Mipope yothira mafutayo imamizidwa mumsanganizo wa asidi wothira.Kutalika kwa kumizidwa kumadalira zinthu monga mtundu ndi makulidwe a oxide wosanjikiza.Pakumizidwa, ndikofunikira kuyang'anira kutentha ndi kuchuluka kwa asidi kuti mukwaniritse zotsatira zomwe mukufuna.
Khwerero 3: Mutsuka Acid: Pambuyo pokolola, mapaipi amatsuka bwino ndi madzi kuchotsa asidi wotsalira.Izi ndizofunikira kuti tipewe zovuta zilizonse zomwe zingachitike pazamankhwala apamtunda wotsatira.

Gawo 3: Kufunika kwa Kutola Zitsulo:
The zitsulo pickling ndondomeko amapereka ubwino ambiri mapaipi zitsulo:
1. Kuchotsa Dzimbiri ndi Sikelo: Kudulira kumachotsa dzimbiri ndi sikelo pazitsulo.Zonyansazi zimatha kusokoneza umphumphu ndi maonekedwe a mapaipi, zomwe zimapangitsa kuti pakhale kuvala msanga komanso kulephera kwapangidwe.
2. Kulimbana ndi Kuwonongeka kwa Ziphuphu: Pochotsa zonyansa, pickling imapanga malo oyera komanso opanda oxide, kumapangitsa kuti zitsulo zisamachite dzimbiri.Izi ndizofunikira makamaka pamapaipi omwe amagwiritsidwa ntchito m'malo ovuta kapena otetezedwa ndi mankhwala ndi chinyezi.
3. Kumamatira Kwambiri: Pickling imakonzekeretsa chitsulo pamwamba pakupanga mawonekedwe okhwima, kulola kuti zokutira kapena mankhwala otsatizana azitsatira bwino.Izi zimatsimikizira kumamatira bwino kwa utoto woteteza kapena zokutira, zomwe zimapangitsa kuti mapaipi achitsulo azikhala olimba.

Gawo 4: Kumvetsetsa Passivation:
Pambuyo pickling, zitsulo mipope kukumana passivation ndondomeko kulenga zoteteza okusayidi wosanjikiza pamwamba.Izi zimatheka ndi kumiza mipope mu passivating wothandizira, makamaka kuchepetsedwa njira ya nitric acid.
Passivation imapanga filimu yopyapyala, yowoneka bwino ya chromium oxide pamwamba pa chitsulo, yomwe imakhala ngati chotchinga pa dzimbiri.Chigawochi chimathandizanso kuti chitsulocho chikhale chokongola komanso chimachepetsa chiopsezo cha kuipitsidwa kapena kusinthika.

Gawo 5: Ubwino wa Passivation:
Passivation imapereka maubwino angapo pamapaipi achitsulo:
1. Kukaniza kwa Corrosion: Mapangidwe a chitetezo cha oxide wosanjikiza kupyolera mu passivation kumapangitsa kuti chitsulo chisawonongeke, kuonetsetsa kuti moyo utalikirapo komanso kuchepetsa zofunikira zosamalira.
2. Kukopa Kokongola: Kuthamanga kumathandiza kusunga maonekedwe a mipope yachitsulo pochepetsa kuthekera kwa madontho pamwamba, kusinthika, kapena madontho a dzimbiri.Izi ndizofunikira makamaka pamapaipi omwe amagwiritsidwa ntchito pomanga kapena kukongoletsa.
3. Thanzi ndi Chitetezo: Kupititsa patsogolo kumapangitsa kuti pakhale malo osakanikirana ndi mankhwala, kuchepetsa chiopsezo cha zitsulo zowonongeka kapena zowonongeka, makamaka m'mapaipi omwe amagwiritsidwa ntchito popereka madzi akumwa kapena zakudya.

Pomaliza:
Pomaliza, pickling zitsulo ndi passivation ndi njira zofunika kwambiri pa njira mankhwala pamwamba pa mipope zitsulo.Kuchotsa bwino zonyansa kudzera mu pickling, kutsatiridwa ndi mapangidwe oteteza oxide wosanjikiza mu passivation, kwambiri timapitiriza durability, kukana dzimbiri, ndi zokongoletsa kukopa mipope zitsulo.Pomvetsetsa kufunikira kwa njirazi, mafakitale amatha kuonetsetsa kuti nthawi yayitali komanso kudalirika kwa mapaipi achitsulo muzogwiritsira ntchito zosiyanasiyana, potsirizira pake amatsogolera ku ntchito yabwino komanso kukhutira kwamakasitomala.
