1. Lub ntsej muag thiab lub cev ntsuas ntawm kev ruaj khov
Koj tuaj yeem ua qhov kev ntsuas pib ua kom muaj zog los ntawm kev saib xyuas kev soj ntsuam thiab kev ntsuam xyuas yooj yim.
| Taw tes | Tsis ruaj khov (theem thaum ntxov) | Ruaj khov (paub ntev patina) |
|---|---|---|
| Xim | Lub teeb Txiv kab ntxwv, liab qab - xim av. Tuaj yeem tsis sib luag. | Ntom, zoo li tsaus xim av, paj yeeb - xim av, lossis russet hues. |
| Kev nyeem ntawv | Kev xeb nyab xeeb xoob xoob xoob, hmoov, lossis flaky. Nws tuaj yeem txhuam ntawm tes. | Nyuaj, adherent, thiab ntom.Nyuaj rau kos tawm nrog ib tug rau tes. |
| Dej ntws | Tseem ceeb.Nag tsim cov dej xeb, streaky dej stains ntawm ib thaj chaw uas nyob ib puag ncig. | Negligible tsis muaj.Lub patina yog impmeleable; Dej hlaws dai thiab khiav tawm kom meej. |
| Lub suab | (Yeem) thaum tapped, tej zaum yuav suab me ntsis npub. | (Yeem) thaum tapped, muaj ib qho denser, siab dua- pitched "ntiv nplhaib." |
2. Cov Txheej Txheem thiab Kev Ntsuas Cov Qauv
Rau cov ntawv thov tseem ceeb (piv txwv li, txuas hniav, qauv), pom kev kuaj xyuas yuav tsum tau muab ntxiv nrog cov txheej txheem nyuaj.
Corrosion ntsuas ntsuas:Qhov no yog cov qauv tseeb tshaj plaws. Lub ntsiab cai tseem ceeb ntawm lub patina ruaj khov yog tias nws txo tus nqi corrosion rau qhov tsis zoo thiab tsis tu ncua tus nqi.
Yuav ua li cas nws ua tiav:Cov Technicians SivUltrasonic Thickness gaugesTxhawm rau ntsuas cov tuab ntawm cov hlau nyob rau tib lub ntsiab lus ntau xyoo.
Cov txheej txheem ruaj khov:Tus nqi ntawm thickness ploj uatas li thiab tsawg heev(feem ntau tsawg dua lossis sib npaug0.002 mm / xyooTom qab stabilization). Yog tias ntsuas ntsuas tsis muaj qhov tseem ceeb ntxiv, lub patina yog ruaj khov.
Kev Kuaj Xyuas:Cov qauv kev ntsuas (piv txwv li,ASTM D 3359 - kab xev xeem) tuaj yeem hloov kho los xyuas seb puas muaj xeb txheej yog sib raug zoo rau cov hlau substrate. Lub Twina ruaj khov yuav tsis muaj kev tshem tawm thaum daim kab xev tshwj xeeb tau siv thiab rub tawm.
Lub sijhawm thiab ib puag ncig:
Cov Sij Hawm:Nyob rau hauv cov huab cua zoo nkauj (nrog ntub dej -} Cov voj voog qhuav), stabilization feem ntau yuav siv1 txog 3 xyoos.
Txoj cai ntawm 60:Ib txoj cai ntawm tus ntiv tes xoo hauv kev lag luam yog qhov kev ruaj ntseg yog qhov ua tiav tom qab cov hlau tau dhau los60 kev ncig ntawm ntub thiab qhuav.
3. Daim npav "Daim npav" - ib txoj kev yooj yim teb
Dav siv thiab siv dag zog kom paub qhov txawv ntawm cov xeb tsis khov yog qhov"Daim npav xeem":
Muab cov tawv ncauj, yas -}}} daim npav noj mov (zoo li daim ntawv tsav tsheb tseem ceeb lossis daim ntawv tsav tsheb).
Sim txhuam cov txheej xeb ntawm cov hlau degnrog cov siab ntseeg.
Qhov tshwm sim:
Yog hais tias lub xeb yog yooj yim scraped tawm, pom cov hlau ci hauv qab, nws yogtsis ruaj.
Yog tias daim npav tawm los tshem tawm cov khoom siv thiab tsuas yog hlawv lossis txhuam cov npoo av, lub patina yoglub nkuaj.
