Munyika yekugadzirwa kwesimbi, kurapwa kwepamusoro kwesimbi isina tsvina inzira yakakosha iyo inowedzera kusimba kwechinhu, kukwezva kwekunaka, uye kuramba mukuora. KuJindalai Steel Company, isu tine hunyanzvi hwekupa zvigadzirwa zvemhando yepamusoro zvesimbi, uye tinonzwisisa kukosha kwemaitiro anoshanda ekurapa pamusoro. Iyi bhurogi ichaongorora mukati meakasiyana simbi isina tsvina pamusoro pekurapa tekinoroji, ichitarisa pane anowanzo itwa maitiro: pickling uye passivation.
Ndedzipi Idzo Nzira dzePamusoro Pakurapa dzeStainless Simbi?
Nzira dzekurapa dzepamusoro dzesimbi isina simbi dzinogona kuiswa zvakaganhurwa mumakanika uye makemikari maitiro. Mechanical nzira dzinosanganisira kukwenenzvera, kukuya, uye kuputika, izvo zvinoshandura panyama nzvimbo kuti inatse kupera kwayo uye kubvisa kusakwana. Nzira dzemakemikari, kune rumwe rutivi, dzinosanganisira kushandiswa kwemhinduro dzakanangana kuti uwane zvivakwa zvaunoda, senge yakawedzera corrosion resistance.
Pickling uye Passivation: Makiyi Matanho
Maviri eanonyanya kushandiswa makemikari epamusoro ekurapa maitiro esimbi isina tsvina ndeye pickling uye passivation.
Pickling inzira inobvisa maokisi, chiyero, uye zvimwe zvinosvibisa kubva pamusoro pesimbi isina tsvina. Izvi zvinowanzoitwa uchishandisa musanganiswa weasidhi, senge hydrochloric kana sulfuric acid. Iyo pickling process haingochenese pasi chete asi zvakare inoigadzirira kune mamwe marapirwo, kuve nechokwadi chekunamira kwakaringana kwemajasi kana kupera.
Passivation, kune rumwe rutivi, inzira inosimudzira yakasikwa oxide layer pasimbi isina tsvina, ichipa chimwe chipingamupinyi kurwisa ngura. Izvi zvinowanzoitwa nekurapa simbi nemhinduro ine citric kana nitric acid. Passivation yakakosha pakuchengetedza kutendeseka kwesimbi isina tsvina munzvimbo dzakaoma, zvichiita kuti ive danho rakakosha mukugadzirisa kwepamusoro.
Yakananga Mirayiridzo yePickling uye Passivation
Kana zvasvika pakunhonga uye passivation, kutevera mirairo chaiyo kwakakosha kuti uwane mibairo yakanaka.
1. Pickling Kurapa Mirayiridzo:
- Ita shuwa kuti nzvimbo yesimbi isina tsvina yakachena uye haina girizi kana tsvina.
-Gadzirira mhinduro yekunhonga zvinoenderana negwara remugadziri, uchive nechokwadi chekusangana chaiko kweasidhi.
- Nyura zvikamu zvesimbi isina tsvina mumhinduro yenguva yakakurudzirwa, kazhinji kubva pamaminetsi mashoma kusvika maawa akati wandei, zvichienderana nekukora kweiyo oxide layer.
- Geza zvakakwana nemvura kuti usaite asidhi uye kubvisa chero masara.
2. Passivation Treatment Instructions:
- Mushure mekunhonga, sukurudza simbi isina tsvina kubvisa chero asidi yasara.
-Gadzirira mhinduro yekumisa, kuve nechokwadi kuti inosangana nezvinodiwa.
- Nyura simbi isina tsvina mumhinduro yekupfuura yenguva yakakurudzirwa, kazhinji pakati pemakumi maviri kusvika makumi matatu maminetsi.
- Shamba nemvura yakasvibiswa kuti ubvise chero yasara passivation mhinduro uye woomesa zvikamu zvachose.
Musiyano pakati pePickling uye Passivation
Nepo zvese zvekunhonga uye passivation zvakakosha pakurapwa kwesimbi isina tsvina, vanoshanda zvakasiyana. Pickling inonyanya kutariswa pakuchenesa pasi uye kubvisa zvinosvibisa, nepo passivation iine chinangwa chekusimudzira inodzivirira oxide layer, kuvandudza corrosion resistance. Kunzwisisa misiyano iyi kwakakosha pakusarudza nzira yakakodzera yekurapa zvichibva pane chaiyo yekushandisa uye mamiriro ezvakatipoteredza.
Mhedziso
PaJindalai Steel Company, tinoziva kuti kurapwa kwepamusoro kwesimbi isina tsvina haisi nhanho chete yekugadzira; chinhu chakakosha chinotarisa hupenyu hurefu uye kushanda kwechigadzirwa chekupedzisira. Nekushandisa tekinoroji yemhando yepamusoro yesimbi isina tsvina, kusanganisira pickling uye passivation, tinoona kuti zvigadzirwa zvedu zvinosangana nemhando yepamusoro uye kusimba. Kunyangwe iwe uri kuda simbi isina simbi yekuvaka, yemotokari, kana chero imwe indasitiri, hunyanzvi hwedu mukugadzirisa simbi pamusoro pemaitiro hunovimbisa kuti iwe unogamuchira mhinduro dzakanakisa dzezvido zvako.
