Ⅰ- WaikawaPikara
1.-Whakamaramatanga oWaikawa-Pickling: Ka whakamahia te waikawa ki te tango matū i te tauine waikura rino i te kukū, te pāmahana me te tere, e kiia nei ko te pickling.
2.- Waikawa-Te whakarōpūtanga īkara: E ai ki te momo waikawa, ka wehea ki te īkara waikawa pungatara, te pīkara waikawa pūhaumāota, te pīkara waikawa nitric, me te pīkara waikawa pūkawa.Me whiriwhiri nga momo paoho rereke mo te tiki i runga i nga rawa o te rino, penei i te pikinga rino waro me te waikawa pungatara me te waikawa pūhaumāota, te pīkara kowiri tira me te ranunga o te waikawa nitric me te waikawa pūhauwai.
E ai ki te ahua o te rino, ka wehea ki te tiki waea, ki te whao, ki te kohi paraharaha, ki te kohi, ki etahi atu.
E ai ki te momo taputapu tiki, ka wehea ki roto ki te tiki tank, ki te kohi haere tonu, ki te tiki tonu tonu, me te pikinga pourewa.
3.- Ko te maapono o te piki waikawa: Ko te tiki waikawa ko te tango i nga unahi waikura rino mai i nga papa whakarewa ma te whakamahi tikanga matū, no reira ka kiia ko te tiki waikawa matū.Ko nga unahi waikura rino (Fe203, Fe304, Fe0) i hangaia i runga i te mata o nga paipa maitai he waikura taketake e kore e rewa ki te wai.Ina rukuhia ki te wairewa waikawa, ka mapuhia ranei ki te wairewa waikawa ki runga i te mata, ka taea e enei waikura taketake te huri i nga huringa matū me te waikawa.
Na te wetewete, te maiengi, me te ngatata o te tauine waikura i runga i te mata o te waro hanganga maitai, te rino koranu iti ranei, i honoa me te pikonga o te tauine waikura me te tira tira i te wa e whakatika ana, e whakatikatika ana, me te kawe i runga i te raina pickling, enei kapiti pore piki ake, ka whakawhānui.Na reira, ka tauhohe te wairewa waikawa ki te tauine waikura ma te matū, ka tauhohe hoki ki te rino takai rino na roto i nga kapiti me nga pores.Arā, i te timatanga o te horoi waikawa, e toru nga tauhohenga matū i waenga i te tauine waikura rino me te whakarewa rino me te wairewa waikawa ka mahia i te wa kotahi ka uru nga unahi waikura rino ki te tauhohenga matū me te waikawa, ka rewa (dissolution) Ka tauhohe te rino me te waikawa. whakaputa hau hauwai, e tihore ana i te tauine o te waikura (te awenga tihorenga miihini) Ko te hauwai ngota i hangaia ka whakaheke i te waikura rino ki te waikura ferrous e ngawari ana ki nga tauhohenga waikawa, katahi ka tauhohe ki nga waikawa ka tangohia (whakaheke).
Ⅱ-Te weriweri/Inactivation/Deactivation
1.- Tikanga Passivation: Ka taea te whakamarama i te tikanga passivation e te ariā kiriata angiangi, e kii ana ko te passivation na te taunekeneke i waenga i nga konganuku me nga matū oxidizing, e whakaputa ana i te tino kikokore, te mato, te hipoki pai, me te tino uru ki runga i te mata whakarewa.Ko tenei paparanga o te kiriata ka noho hei waahanga motuhake, ko te tikanga he puhui o nga konganuku waikura.Ka whai waahi ki te wehe katoa i te whakarewa mai i te reo kino, te aukati i te whakarewa mai i te uru ki te waahi kino, na reira ka mutu te whakakore o te konganuku me te hanga i te ahua hauhau kia tutuki ai te paanga anti-corrosion.
2.- Nga painga o te haere noa:
1) Ka whakatauritea ki nga tikanga hiri a-tinana tuku iho, ko te maimoatanga passivation te ahuatanga o te tino kore e whakanui ake i te matotoru o te mea mahi me te whakarereke i te tae, te whakapai ake i te tika me te uara taapiri o te hua, kia pai ake te mahi;
2) Na te kore tauhohenga o te tukanga passivation, ka taea te taapiri me te whakamahi i te kaihoko passivation, ka roa ake te oranga me te utu ohaoha.
3) Ka whakatairangahia e te Passivation te hanga o te kiriata hāora i te hanga rāpoi hāora i runga i te mata whakarewa, he mea kiato me te pūmau i roto i te mahi, me te whai mana whaiaro whakatika i roto i te rangi i te wa ano.Na reira, whakaritea ki te tikanga tuku iho o te paninga hinu antirust, te kiriata passivation hanga e passivation he atu pūmau me te waikura ātete.Ko te nuinga o nga paanga o te utu i roto i te paparanga waikura e pa ana ki te tukanga o te waiariki.I roto i te awhe pāmahana o 800-1250℃, ko te tukanga waiariki waiariki e whakamahi ana i te hāora maroke, te hāora mākū, te kohu wai rānei e toru ngā wāhanga tonu.Tuatahi, ka uru te hāora i roto i te hau taiao ki roto i te paparanga waikura i hangaia, katahi ka marara te hāora ki roto ma roto i te hauhā.Ka tae atu ki te atanga Si02-Si, ka tauhohe ki te hiraka ki te hanga i te hauhaurua hou.Ma tenei ara, ka puta tonu te mahi o te tauhohenga whakamaoritanga urunga o te hāora, ka huri tonu te silicon tata ki te atanga ki te silica, ka tipu te paparanga waikura ki roto o te angiangi silicon i tetahi tere.
Ⅲ- Phosphating
Ko te maimoatanga Phosphating he tauhohenga matū ka hanga he paparanga kiriata (kiriata phosphating) i runga i te mata. Ko te tukanga maimoatanga phosphating te nuinga e whakamahia ana i runga i nga mata whakarewa, me te kaupapa ki te whakarato i tetahi kiriata whakamarumaru hei wehe i te whakarewa mai i te hau me te aukati i te pirau;Ka taea hoki te whakamahi hei tuatahi mo etahi hua i mua i te peita.Ma tenei paparanga o te kiriata phosphating, ka taea e ia te whakapai ake i te taapiri me te aukati i te waikura o te paparanga peita, te whakapai ake i nga taonga whakapaipai, me te ahua ataahua o te mata whakarewa.Ka taea hoki e ia te mahi whakahinuhinu i etahi o nga mahi mahi makariri.
I muri i te maimoatanga phosphating, e kore te mea mahi e oxidize waikura ranei mo te wa roa, na te tono o te maimoatanga phosphating he tino whānui, me te hoki he tukanga maimoatanga mata whakarewa nuitia whakamahia.Kei te kaha ake te whakamahi i roto i nga umanga penei i nga motuka, kaipuke, me nga mahi miihini.
1.- Te whakarōpūtanga me te tono o te phosphating
I te nuinga o te wa, he rereke te tae o te maimoatanga mata, engari ko te maimoatanga phosphating ka taea te whakatau i runga i nga tino hiahia ma te whakamahi i nga momo phosphating hei whakaatu i nga tae rereke.Koinei te take ka kite tatou i te maimoatanga phosphating i te hina, te tae, te pango ranei.
Te phosphating rino: i muri i te phosphating, ka whakaatu te mata te tae aniwaniwa me te puru, no reira ka kiia hoki ko te ūkuikui tae.Ko te otinga phosphating te nuinga whakamahi molybdate rite rauemi mata, e ka hanga he kiriata phosphating tae aniwaniwa i runga i te mata o ngā rauemi maitai, me te hoki te nuinga whakamahia ki te peita i te paparanga raro, kia rite ki te whakatutuki i te waikura ātete o te workpiece me te whakapai ake i te adhesion. o te paninga mata.
