Thaum nws los txog rau kev ntsuam xyuas ntsev tsuag, nws yuav tsum ua kom tiav nrog kev pab los ntawm antsev tsuag kuaj chamber.
Covntsev tsuag kuaj chamberntsuam xyuas cov ntsev tsuag corrosion muaj peev xwm ntawm cov ntaub ntawv thiab lawv cov txheej txheem tiv thaiv, thiab sib piv cov txheej txheem zoo ntawm cov txheej txheem tiv thaiv zoo sib xws.
Ntsev tshuaj tsuag chambertseem tuaj yeem ntsuas lub peev xwm ntawm qee yam khoom los tiv thaiv ntsev tsuag corrosion. Cov khoom no yog siv rau hauv cov khoom siv, cov khoom siv hluav taws xob ntsev tsuag tshuaj tiv thaiv corrosion ntawm cov khoom, cov txheej txheem tiv thaiv ntawm cov ntaub ntawv hlau thiab cov khoom lag luam;
1. Yam khoom twg yuav tsum tau kuaj tshuaj ntsev?
Hlau thiab lawv cov alloys
hlau npog
organic npog
anodized zaj duab xis
2. Npog txheej
1) Npog txheej txheej
Organic coatings, xws li xim, kua roj vanish, hmoov txheej, anti-xeb roj, thiab lwm yam.
Hlau txheej, xws li electroplating, tshuaj plating, ion plating, tshuaj tsuag plating, kub dip plating, tshuaj vapor deposition, thiab lwm yam. Feem ntau siv electroplating txheej xws li zinc plating, tooj liab plating, npib tsib xee plating, chromium plating, tin plating, tooj dag plating, txhuas. - tin alloy plating, thiab lwm yam.
2) Kev ua haujlwm ntawm npog txheej
Aesthetics Piv txwv li: ci chrome plating
Tiv thaiv lub hauv paus hlau los ntawm corrosion
3. Kev faib tawm ntawm cov txheej txheem rau kev kuaj ntsev tsuag
Neutral ntsev tsuag test (NSS)
Acetic acid ntsev tsuag Test (AASS)
Copper Accelerated Acetic Salt Spray Test (CASS)
Feem ntau siv hom qauv: ISO 9227: 2006 Europe (xws li United Kingdom)
ASTM B117-03 Tebchaws Asmeskas
DIN 50021: 1988 Lub teb chaws Yelemees
(1) Neutral ntsev tsuag tshuaj ntsuam NSS (Neutral ntsev tsuag)
Kuaj cov qauv xaiv
ISO 9227: 2006 Europe (xws li UK)
ASTM B117-03 Tebchaws Asmeskas
DIN 50021: 1988 Lub teb chaws Yelemees
Cov xwm txheej ntawm ntau cov qauv xeem yog tib yam, saib cov ntsiab lus hauv qab no
Kev Xeem
Sodium chloride kua concentration 50g / L ± 5g / L
PH tus nqi yog 6.5 ~ 7.2
Qhov ntsuas kub hauv chav kuaj yog 35 ± 2 degree
(USA 35＋1.1/-1.7 degree)
Cov tshuaj tsw qab ntsev yog 1.5 ± 0.5mL ib 80 cm² ib teev twg
Kev npaj ua qauv
Hom, kom muaj nuj nqis, cov duab, thiab qhov loj ntawm cov qauv yog txiav txim siab raws li cov qauv khoom. Yog tias tsis muaj tus qauv, nws yuav tsum tau sib tham los ntawm cov neeg koom nrog.
Cov qauv yuav tsum tau muab ntxuav los ntawm kev siv cov txheej txheem tsim nyog ua ntej kuaj, tab sis cov ntaub ntawv tiv thaiv organic txhob txwm coated ntawm cov qauv yuav tsum tsis txhob muab ntxuav tawm.
Rau cov qauv txiav, qhov chaw txiav yuav tsum tau tiv thaiv nrog cov xim, paraffin wax lossis daim kab xev.
Qauv tso
Cov qauv no tau muab tso rau hauv lub thawv tshuaj tsuag ntsev nrog qhov ntsuas qhov ntsej muag, thiab cov tshuaj tsuag ntsev tau tso cai rau kev ywj pheej ntawm qhov chaw sim. Qhov chaw kuaj tsis tuaj yeem raug txau ncaj qha los ntawm tshuaj tsuag ntsev.
Qhov chaw kuaj ntawm tus qauv yuav tsum nyob ntawm lub kaum sab xis ntawm 20 degrees mus rau txoj kab ntsug.
Cov khoom tuaj yeem muab tso rau ntawm ntau theem hauv lub thawv, tab sis lawv yuav tsum tsis txhob sib cuag nrog ib leeg lossis hauv lub thawv, thiab cov tee dej ntawm cov qauv yuav tsum tsis txhob poob rau lwm cov qauv.
Tus qauv tuav yog ua los ntawm iav, yas thiab lwm yam ntaub ntawv. Cov khoom siv rau dai cov qauv tsis tuaj yeem yog hlau, tab sis yuav tsum tau ua los ntawm cov ntaub ntawv insulating xws li fiber.
Lub sijhawm kuaj
Lub sijhawm xeem yog txiav txim siab raws li cov khoom sib txawv. Feem ntau hais lus, nws yog 2/4/6/8/24 teev. Yog tias nws ntau dua 24 teev, nws yog qhov sib npaug ntawm 24 teev.
Tom qab kev sim ua piv txwv tuav
Tom qab kev sim, tshem tawm cov qauv thiab ziab nws nyob hauv tsev rau 0.5 mus rau 1 teev, tom qab ntawd maj mam yaug nws nrog dej huv uas muaj qhov kub tsis siab tshaj 40 degrees Celsius kom tshem tawm cov tshuaj ntsev ntxiv, thiab tom qab ntawd tshuab ziab tam sim ntawd nrog lub tshuab plaub hau.
