Nhanganyaya yeAcid Pickling uye Passivation
Mapombi esimbi anoshandiswa zvakanyanya mumaindasitiri akasiyana siyana nekuda kwekusimba kwazvo, simba, uye corrosion kuramba. Nekudaro, kuti ive nechokwadi chekuita kwavo kwakakwana uye hupenyu hurefu, zvakakosha kuita nzira dzinoshanda dzekurapa pamusoro senge simbi pickling uye passivation. Iyi blog ine chinangwa chekujekesa kukosha kwemaitiro aya mukusimudzira kunaka nekusimba kwepombi dzesimbi.
Chikamu 1: Chii chinonzi Steel Pickling?
Steel pickling ikemikari nzira inosanganisira kubviswa kwetsvina, senge ngura, chiyero, uye oxides, kubva pamusoro pepombi dzesimbi. Chinangwa chekutanga chekunhonga ndechekuchenesa simbi yepasi zvakakwana, kuigadzirira kune inozotevera kurapwa kwepamusoro senge passivation.
Munguva yekutora, mapaipi esimbi anonyudzwa mune acidic mhinduro, inowanzo sanganisira hydrochloric kana sulfuric acid. Asidhi inopindirana netsvina, ichinyunguduka uye ichiibvisa kubva pamusoro pesimbi, ichisiya yakachena uye yakatsetseka kupera.
Chikamu 2: Maitiro ekunhonga:
Iyo pickling process inosanganisira akati wandei matanho ekuona kubviswa kunoshanda kwetsvina kubva pamapombi esimbi:
Danho 1: Kubvisa mafuta: Usati wanhonga, pombi dzesimbi dzinodzikiswa kubvisa chero mafuta, girisi, kana tsvina iripo pamusoro. Iyi nhanho inovimbisa kuti asidhi inogona kupindirana zvakananga netsvina iri pamusoro pesimbi.
Danho rechipiri: Kunyudzwa kweasidhi: Mapombi akacheneswa anobva anyudzwa mumushonga wepickling acid. Nguva yekunyudzwa inoenderana nezvinhu zvakaita serudzi uye ukobvu hweiyo oxide layer. Panguva yekunyudzwa, zvakakosha kutarisa tembiricha uye kusungirirwa kweasidhi kuti uwane mhedzisiro inodiwa.
Danho rechitatu: Acid Rinse: Mushure mekuita pickling, pombi dzinonyatsosukurudzwa nemvura kubvisa chero yakasara asidhi. Iyi nhanho yakakosha kudzivirira chero inogona kuitika kemikari inogona kuitika panguva yekutevera kurapwa kwepamusoro.
Chikamu 3: Kukosha kweSimbi Kunhonga:
Iyo simbi yekunhonga maitiro inopa akawanda mabhenefiti emapombi esimbi:
1. Rust and Scale Removal: Pickling inonyatso bvisa ngura uye chiyero kubva pamusoro pesimbi. Izvi zvinosvibisa zvinogona kukanganisa kutendeseka uye kutaridzika kwepombi, zvichiita kuti pave nekupfeka nguva isati yakwana uye kukanganisa kwemaitiro.
2. Yakanatsiridza Corrosion Resistance: Nekubvisa tsvina, pickling inogadzira nzvimbo yakachena uye isina oxide, inosimudzira kuramba kwesimbi pakuora. Izvi zvinonyanya kukosha kune mapaipi anoshandiswa munzvimbo dzakaoma kana kuratidzwa kune makemikari nehunyoro.
3. Enhanced Adhesion: Pickling inogadzirira nzvimbo yesimbi kuburikidza nekugadzira chimiro chakaomeswa, ichibvumira machira anotevera kana marapirwo kuti atevedze zvakanyanya. Izvi zvinovimbisa kunamatira zviri nani kwepende yekudzivirira kana machira, zvichibatsira pakugara kwenguva refu kwepombi dzesimbi.
Chikamu 4: Kunzwisisa Passivation:
Mushure mekunhonga, mapaipi esimbi anopinda maitiro ekufambisa kugadzira inodzivirira oxide layer pamusoro. Izvi zvinowanikwa nekunyudza mapaipi mune inodarika ajenti, kazhinji mhinduro yakanyungudutswa yenitric acid.
Passivation inoumba firimu rakatetepa, rakajeka re chromium oxide pamusoro pesimbi, iyo inoshanda sechipinganidzo kurwisa ngura. Iyi layer inobatsirawo kuchengetedza kunaka kwesimbi uku ichideredza njodzi yekusviba kana kushanduka.
Chikamu 5: Zvakanakira Passivation:
Passivation inopa akati wandei mabhenefiti emapombi esimbi:
1. Corrosion Resistance: Kuumbwa kwechidziviriro che oxide layer kuburikidza ne passivation kunowedzera zvakanyanya kusimba kwesimbi, kuve nechokwadi chehupenyu hurefu uye kuderedza zvinodiwa zvekugadzirisa.
2. Aesthetic Appeal: Passivation inobatsira kuchengetedza chitarisiko chepombi dzesimbi kuburikidza nekuderedza mukana wepanyika tsvina, kushanduka kwemavara, kana makwapa emarara. Izvi zvinonyanya kukosha kune mapaipi anoshandiswa mukugadzira kana kushongedza zvikumbiro.
3. Hutano uye Kuchengeteka: Passivation inogadzira nzvimbo ine makemikari inert, kuderedza njodzi yekubuda kwesimbi kana kusvibiswa, kunyanya mumapombi anoshandiswa kufambisa mvura yekunwa kana zvigadzirwa zvekudya.
Mhedziso:
Mukupedzisa, kunhonga simbi uye passivation matanho akakosha mukugadzirisa kwepamusoro maitiro epombi dzesimbi. Kubudirira kubviswa kwetsvina kuburikidza ne pickling, inoteverwa nekugadzirwa kweinodzivirira oxide layer mu passivation, inosimbisa zvakanyanya kusimba, kusaita ngura, uye aesthetic kukwezva kwepombi dzesimbi. Nekunzwisisa kukosha kwemaitiro aya, maindasitiri anogona kuve nechokwadi chekugara kwenguva refu uye kuvimbika kwepombi dzesimbi mumashandisirwo akasiyana-siyana, pakupedzisira zvichitungamira mukuvandudza mashandiro uye kugutsikana kwevatengi.
