Gabatarwar Acid Pickling da Passivation
Ana amfani da bututun ƙarfe a ko'ina a masana'antu daban-daban saboda kyakkyawan ƙarfin su, ƙarfi, da juriya na lalata. Duk da haka, don tabbatar da mafi kyawun aikin su da tsawon rai, yana da mahimmanci don aiwatar da ingantattun hanyoyin jiyya na ƙasa kamar tsinkar ƙarfe da wucewa. Wannan shafin yana da nufin ba da haske kan mahimmancin waɗannan matakai wajen haɓaka inganci da dorewar bututun ƙarfe.
Sashi na 1: Menene Pickling Karfe?
Tushen ƙarfe wani tsari ne na sinadari wanda ya haɗa da cire ƙazanta, kamar tsatsa, sikeli, da oxides, daga saman bututun ƙarfe. Babban dalilin pickling shine tsaftace karfen da kyau, shirya shi don jiyya na gaba kamar wucewa.
A lokacin aikin tsinke, ana nitsar da bututun ƙarfe a cikin maganin acidic, yawanci ya ƙunshi hydrochloric ko sulfuric acid. Acid ɗin yana amsawa tare da ƙazanta, narkar da su kuma cire su daga saman karfe, yana barin ƙare mai tsabta da santsi.
Sashi na 2: Tsarin Zaɓe:
Tsarin pickling ya ƙunshi matakai da yawa don tabbatar da ingantaccen kawar da ƙazanta daga bututun ƙarfe:
Mataki na 1: Ragewa: Kafin tarawa, ana zubar da bututun ƙarfe don cire duk wani mai, maiko, ko datti a saman. Wannan matakin yana tabbatar da cewa acid zai iya yin hulɗa kai tsaye tare da ƙazantattun da ke kan saman ƙarfe.
Mataki na 2: Zubar da Acid: Daga nan ana nutsar da bututun da aka lalatar a cikin maganin tsinken acid. Tsawon lokacin nutsewa ya dogara da abubuwa kamar nau'i da kauri na Layer oxide. A lokacin nutsewa, yana da mahimmanci don saka idanu da zafin jiki da tattarawar acid don cimma sakamakon da ake so.
Mataki na 3: Rinse Acid: Bayan aikin da aka gama, ana wanke bututu da ruwa sosai don cire duk wani ragowar acid. Wannan matakin yana da mahimmanci don hana duk wani yuwuwar halayen sinadaran da zai iya faruwa yayin jiyya na gaba.
Sashi na 3: Muhimmancin Tabar Karfe:
Tsarin pickling na karfe yana ba da fa'idodi masu yawa don bututun ƙarfe:
1. Tsatsa da Cire Sikelin: Pickling yadda ya kamata yana kawar da tsatsa da sikelin daga saman karfe. Waɗannan ƙazanta na iya yin lahani ga mutunci da bayyanar bututu, wanda zai haifar da lalacewa da wuri da yuwuwar gazawar tsarin.
2. Ingantacciyar Juriya na Lalacewa: Ta hanyar cire ƙazanta, pickling yana haifar da tsaftataccen wuri mara oxide, yana haɓaka juriyar ƙarfe ga lalata. Wannan yana da mahimmanci musamman ga bututun da ake amfani da su a cikin yanayi mai tsauri ko fallasa ga sinadarai da danshi.
3. Ingantaccen adhesion: pickling Shirya farfajiya na karfe ta hanyar ƙirƙirar kayan aikin roughedend, ba da izinin sutura mai zuwa ko jiyya don adreerya sosai. Wannan yana tabbatar da mafi kyawun mannewa na fenti mai kariya ko sutura, yana ba da gudummawa ga tsayin daka na bututun ƙarfe.
Sashi na 4: Fahimtar Ƙunƙwasa:
Bayan dasa shuki, bututun ƙarfe suna yin aikin wucewa don ƙirƙirar Layer oxide mai kariya a saman. Ana samun wannan ta hanyar nutsar da bututu a cikin wakili mai wucewa, yawanci maganin nitric acid.
Passivation ya samar da fim na bakin ciki, bayyanannen fim na chromium oxide a saman karfe, wanda ke aiki a matsayin shinge ga lalata. Har ila yau, wannan Layer yana taimakawa wajen kula da kyawawan kayan ƙarfe yayin da yake rage haɗarin tabo ko canza launin.
Sashi na 5: Fa'idodin Cirewa:
Passivation yana ba da fa'idodi da yawa don bututun ƙarfe:
1. Juriya na Lalacewa: Samuwar Layer oxide mai kariya ta hanyar wucewa yana haɓaka juriya na lalata karfe, yana tabbatar da tsawon rayuwa da rage bukatun kulawa.
2. Aesthetic Appeal: Passivation taimaka kula da gani gani na karfe bututu ta rage yiyuwar na saman tabo, discoloration, ko tsatsa spots. Wannan yana da mahimmanci musamman ga bututun da aka yi amfani da su a aikin gine-gine ko kayan ado.
3. Lafiya da Aminci: Passivation yana haifar da wani wuri marar amfani da sinadarai, yana rage haɗarin zubewar ƙarfe ko gurɓata, musamman a cikin bututun da ake amfani da su don isar da ruwan sha ko kayan abinci.
Ƙarshe:
A ƙarshe, pickling karfe da passivation matakai ne masu mahimmanci a cikin matakan jiyya na saman don bututun ƙarfe. Ingantacciyar kawar da ƙazanta ta hanyar tsintsawa, sannan samuwar Layer oxide mai karewa a cikin wucewa, yana haɓaka dagewa sosai, juriya na lalata, da ƙawata bututun ƙarfe. Ta hanyar fahimtar mahimmancin waɗannan hanyoyin, masana'antu na iya tabbatar da tsawon rai da amincin bututun ƙarfe a cikin aikace-aikace daban-daban, a ƙarshe yana haifar da ingantaccen aiki da gamsuwar abokin ciniki.
