1, Stainless hlau yog dab tsi?
Stainless hlau yog ib hom hlau.Hlau yog hais txog cov hlau uas muaj tsawg dua 2% carbon (c), thiab ntau dua 2% hlau.Alloy cov ntsiab lus xws li chromium (CR), npib tsib xee (Ni), manganese (MN), silicon (SI), titanium (TI) thiab molybdenum (MO) ntxiv rau cov hlau hauv cov txheej txheem smelting los txhim kho kev ua haujlwm ntawm cov hlau thiab ua kom cov hlau muaj corrosion kuj (xws li tsis xeb), uas yog qhov peb feem ntau hu ua stainless hlau.Piv txwv li, peb cov khoom siv stainless hlau:banjos, swivel house kawg sib koom,tsev clamps,tso manifold, lwm.
2, Vim li cas stainless hlau xeb?
Stainless hlau muaj peev xwm tiv taus atmospheric oxidation - xeb kuj, thiab kuj muaj peev xwm tiv thaiv corrosion nyob rau hauv nruab nrab uas muaj acid, alkali thiab ntsev, uas yog, corrosion kuj.Txawm li cas los xij, qhov corrosion kuj ntawm cov hlau sib txawv nrog nws cov tshuaj muaj pes tsawg leeg, kev sib nrig sib lub xeev, kev pab cuam thiab ib puag ncig nruab nrab hom.
Stainless hlau yog ib qho nyias nyias, ruaj khov thiab zoo ruaj khov chromium nplua nuj oxide zaj duab xis (tiv thaiv zaj duab xis) tsim rau ntawm nws qhov chaw los tiv thaiv cov pa atoms los ntawm kev nkag mus thiab oxidize, thiab tau txais kev tiv thaiv corrosion.Thaum cov yeeb yaj kiab tsis tu ncua vim qee qhov laj thawj, cov pa oxygen atoms hauv huab cua lossis kua yuav nkag mus tsis tu ncua lossis cov hlau atoms hauv cov hlau yuav tsis tu ncua cais tawm, tsim cov hlau oxide xoob, thiab cov hlau saum npoo yuav tsis tu ncua corroded.Muaj ntau hom kev puas tsuaj rau lub ntsej muag lub ntsej muag, thiab cov hauv qab no muaj ntau hauv lub neej txhua hnub:
1. Cov plua plav uas muaj lwm yam hlau lossis cov khoom sib txuas ntawm cov hlau tsis sib xws yog khaws cia rau saum npoo ntawm stainless hlau.Nyob rau hauv cov huab cua ntub, cov condensate ntawm cov ntawv txuas thiab cov hlau tsis muaj hlau txuas rau hauv micro cell, ua rau cov tshuaj tiv thaiv electrochemical thiab ua rau cov yeeb yaj kiab tiv thaiv, uas yog hu ua electrochemical corrosion.
2. Organic kua txiv (xws li melons thiab zaub, noodle kua zaub thiab phlegm) adheres rau saum npoo ntawm stainless hlau.Nyob rau hauv lub xub ntiag ntawm dej thiab oxygen, lawv tsim cov organic acids, uas yuav corrode hlau nto rau lub sij hawm ntev.
3. Qhov saum npoo ntawm stainless hlau yog adhered nrog cov kua qaub, alkali thiab ntsev (xws li dej alkali thiab txiv qaub dej tshuaj tsuag rau phab ntsa kho kom zoo nkauj) ua rau lub zos corrosion.4. Nyob rau hauv cov huab cua tsis zoo (cov huab cua uas muaj ntau cov sulfide, oxide thiab hydrogen oxide), thaum ntsib cov dej condensed, sulfuric acid, nitric acid thiab acetic acid kua ntsiab lus yuav tsim, ua rau cov tshuaj corrosion.
3, Yuav ua li cas los daws cov xeb ntawm cov hlau tsis huv?
a) Cov txheej txheem tshuaj:
Siv cov tshuaj pleev xim los yog tshuaj tsuag los pab cov khoom xeb kom rov ua dua thiab tsim cov chromium oxide zaj duab xis kom rov ua kom cov corrosion kuj.Tom qab pickling, nws yog ib qho tseem ceeb heev uas yuav tsum tau ntxuav nrog dej huv kom tshem tawm tag nrho cov pa phem thiab acid residue.Tom qab tag nrho cov kev kho mob, siv cov cuab yeej polishing los polish dua thiab khi nrog polishing ciab.Rau cov neeg uas muaj xeb me ntsis hauv zos, 1: 1 sib xyaw ntawm cov roj av thiab cov roj cav tuaj yeem siv los so cov pob xeb nrog cov ntaub qhwv huv.
b) Mechanical method:
Blast tu, tua blasting nrog iav los yog ceramic hais, rhuav tshem, txhuam thiab polishing.Nws muaj peev xwm los so tawm cov kab mob uas tshwm sim los ntawm cov khoom siv yav dhau los tshem tawm, polishing cov ntaub ntawv lossis cov ntaub ntawv rhuav tshem los ntawm kev siv tshuab.Txhua yam kev ua qias tuaj, tshwj xeeb tshaj yog cov hlau txawv teb chaws, yuav dhau los ua qhov chaw ntawm corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig ntub.Yog li ntawd, lub tshuab ntxhua khaub ncaws yuav tsum zoo dua yuav tsum raug ntxuav hauv qhov chaw qhuav.Cov txheej txheem siv tshuab tsuas tuaj yeem ntxuav qhov chaw, thiab tsis tuaj yeem hloov qhov corrosion kuj ntawm cov khoom nws tus kheej.Yog li ntawd, nws raug nquahu kom rov polish nrog cov khoom siv polishing tom qab kho tshuab thiab foob nrog polishing ciab.
