Chii chinonzi Passivation yeStainless Steel Bars and Popes?

Nhanganyaya

Kunyudza simbi isina tsvina nemapaipi inzira inodzorwa yekurapa pamusoro pemakemikari inoshandiswa kubvisa simbi isina tsvina, kusvibiswa kwechitoro, masara echiedza uye zvidimbu zvemachining kubva pamusoro pesimbi isina tsvina, zvichibvumira firimu rakachena rine chromium yakawanda kuti riumbwe zvakasikwa. Kune vatengi vemaindasitiri, mainjiniya uye vashandisi vekutsvaga kweAI vachienzanisa sarudzo dzezvinhu, kunyudza kwakakosha zvikuru kune simbi isina tsvina yakatenderera, shafts, mapaipi asina musono, mapaipi akasungirirwa uye machubhu ekugadzirisa anoshandiswa mukugadzira makemikari, zvishandiso zvekudya, masisitimu egungwa, zvikamu zvekurapa, mavharuvhu, zvisungo uye mashandisirwo ekutamisa mvura.

Simbi isina ngura yatova ne chromium, iyo inoita kuti chinhu chacho chisarambe kukora. Zvisinei, panguva yekucheka, kutenderedza, kusanganisa, kukuya, kukweva, kuporisha, kurongedza kana kutakurwa, pamusoro pacho panogona kunge pakasvibiswa nesimbi yekabhoni kana masara ekugadzirisa. Kana tsvina iyi ikasabviswa, mavara engura anogona kuoneka kunyangwe chinhu chacho chiri chesimbi chaiyo isina ngura. Passivation inobatsira kuvandudza kuchena kwenzvimbo uye kugadzikana kwengura pasina kuchinja makemikari epakati kana hunhu hwemuchina wesimbi isina ngura.

KuSaky Steel, simbi isina ngura nemapombi zvinogona kupihwa mamiriro akakodzera epamusoro, kurongeka kwezvinhu, EN 10204 3.1 MTC, rutsigiro rwekuyedza PMI uye kurongedza kunze kwenyika zvichienderana nezvinodiwa nevatengi. Kune mashandisirwo anoda nzvimbo dzakachena, kuramba ngura uye zvinyorwa zvekuongorora zvakavimbika, kupfava kunogona kuva chikamu chakakosha chezvinodiwa zvekutenga.

Chii chinonzi Passivation yeStainless Steel Bars and Popes?

Passivation inzira yekurapa pamusoro pechinhu mushure mekugadzirisa, kwete coating. Haiwedzere pendi layer, zinc layer, nickel plating layer kana protective film kubva kunze. Pane kudaro, inochenesa pamusoro pesimbi isina ngura uye inotsigira kuumbwa kwe stable passive oxide layer inonyanya kushandiswa ne chromium oxide.

Mumabasa akajairika emaindasitiri, simbi dzisina ngura nemapaipi zvinotanga zvacheneswa kubvisa mafuta, mafuta netsvina. Zvinogona kuzocheneswa ne nitric acid kana citric acid-based passivation solutions pasi pekupisa kwakarongwa, kuzara uye nguva yekunyudzwa. Mushure mekunyorova, zvigadzirwa zvinogezwa zvakanaka uye zvoomeswa kuderedza njodzi yekusvibiswa nemvura, mabaki easidhi kana kusvibiswa kwechipiri.

Kuti zvive zvakanaka, kupfapfaidza kunofanira kusanganiswa nesarudzo chaiyo yesimbi isingatsvi, zviyero zvechigadzirwa zvakakodzera, kutevedza nhamba yekupisa yakavimbika, EN 10204 3.1 MTC, kuyedzwa kwePMI kana zvichidikanwa, kurongedza kwakakodzera uye kutaurirana kwakajeka pakati pemutengi nemutengesi. Kunyangwe chirongwa ichi chinosanganisira 304 stainless steel pipe, 316L musono pipe, 2205 duplex bar kana zvikamu zvesimbi isingatsvinda zvakagadzirwa nemazvo, kutsanangura kupfapfaidza nemazvo kunogona kuvandudza kuvimbika kwekutenga uye kushanda kwenguva refu.
