1. Kev kho deg
Qhov saum npoo ntawm lub valve yuav tsum tau pleev xim rau yuav tsum tau kho raws li qhov yuav tsum tau ua hauv qab no.
① Qhov saum npoo ntawm lub valve yuav tsum tau pleev xim rau yuav tsum tau kho ua ntej kom nruj raws li cov txheej txheem kev kho mob substrate yuav tsum tau ua los ntawm cov chaw tsim tshuaj pleev xim lossis cov txheej txheem kho deg rau daim ntawv thov xim teev los ntawm tus neeg siv.
② Siv cov tshuaj ntxuav kom tsim nyog kom tshem tawm cov stains thiab roj ua ntej kho qhov chaw.
③ Kev kho saum npoo yuav tsum tau nqa tawm saum toj 3 degree saum toj no qhov dew point kub thiab qis dua 80% txheeb ze av noo.
④ Yog tias muaj cov kev cai tshwj xeeb rau kev xuab zeb blasting lossis txhaj tshuaj blasting, qhov saum npoo yuav tsum tsis muaj oxide daim tawv nqaij, xeb thiab lwm yam kab mob.
⑤ Kev kho saum npoo ntawm cov khoom siv valve yuav tsum tau txau tsis pub dhau 3h, ntau dua 3h kev kho saum npoo yuav tsum tau ua dua.
2. Xim txheej
Xim txheej yuav tsum tau ua raws li cov kev cai hauv qab no.
① Painting tej yam kev mob yuav tsum ua raws li cov kev cai ntawm cov khoom specification.
② nruj me ntsis raws li qhov ntim piv lossis qhov hnyav piv rau pawg piv.
③ Tus neeg sawv cev tseem ceeb thiab tus neeg sawv cev kho yuav tsum muab sib xyaw nrog lub tshuab fais fab. Hauv tus neeg sawv cev tseem ceeb los koom nrog tus neeg sawv cev kho, koj yuav tsum siv lub tshuab hluav taws xob sib xyaw kom sib xyaw, lub sijhawm no raws li qhov yuav tsum tau ntxiv diluent sib tov tom qab siv, diluent yuav tsum raug xaiv kom haum rau cov qauv specifications, tsis txhob sib piv cov diluent tau. tsis siv arbitrarily.
④ Raws li kev xaiv ntawm cov khoom siv pleev xim sib txawv (xws li txhuam, cov menyuam, tes txau lossis electrostatic txau), lub thickness ntawm cov txheej yog txawv, qhov kev xaiv ntawm cov sij hawm cov xim txawv, feem ntau 3 zaug.
⑤ Yog tias koj xaiv cov xim txhuam hniav, cov kev taw qhia ntawm kev pleev xim yuav tsum tau ua ntej nce thiab nqis tom qab sab laug thiab sab xis los pleev xim, txhuam dipping xim tsis tuaj yeem ntau dhau, txhuam cov xim nyob deb tsis tuaj yeem loj heev kom tsis txhob muaj xim. zaj duab xis nyias dhau lawm. Yog tias koj xaiv cov tshuaj tsuag, rab phom yuav tsum tau txav mus los, txhua lub sijhawm los npog ib nrab ntawm qhov kawg ntawm kev txav mus los kom ntseeg tau tias cov xim zaj duab xis tuab ntawm txhua feem ntawm cov khaub ncaws.
(6) vim yog lub valve qhib thiab kaw txwv cov cuab yeej tshwm sim los ntawm lub valve hauv zos npog, hauv cov xim yuav tsum qhib thiab kaw lub valve rau tha xim (xws li pob li qub, ntsaws li qub, txwv txoj haujlwm thaiv, thiab lwm yam).
(vii) sab nraub qaum ntawm lub valve 3 flanges thiab hauv qab ntawm lub valve yuav tsum tau pleev xim rau qhov sib npaug, qhov kawg flange qhov yuav tsum tau dipped hauv epoxy zinc-nplua nuj los tiv thaiv xeb xim txhuam.
⑧ pleev xim rau primer yuav tsum tau siv ib daim ntaub emery los yog sandpaper los kho cov primer du thiab tiaj tus.
Lub sijhawm uas tuaj yeem siv tau tom qab sib xyaw cov xim sib txawv nrog hom xim. Nws yog ib qho kev tswj ob npaug ntawm lub sijhawm thiab qhov kub thiab txias, qhov kub thiab txias, lub sijhawm luv dua.
⑩ yuav tsum nruj me ntsis raws li cov xim tuaj yeem rov txheej txheej thiab lub sijhawm ziab kom ua.
3. General xim txau thickness
Rau cov xim tuab ntawm qhov tsis ua tiav ntawm lub valve, nws raug pom zoo tias thawj txheej yuav tsum tau coated nrog epoxy zinc nplua nuj antirust xim m, txheej thib ob yuav tsum tau coated nrog epoxy ferric oxide antirust xim 20μm, thiab peb txheej. yuav tsum tau coated nrog epoxy sab saum toj txheej nrog ib tug qhuav zaj duab xis thickness ntawm 25μm.
4. Kev ceev faj txog kev pleev xim
Kev ceev faj rau kev pleev xim yog raws li hauv qab no.
① Tom qab sib tov cov xim, nws yog txwv tsis pub siv cov xim uas tshaj lub sijhawm siv tau.
② Cov cua compressed siv rau cov xim pleev xim yuav tsum yog de-roj thiab de-watered, thiab tuaj yeem siv rau pleev xim tsuas yog thaum nws siab tshaj 3 degree saum cov dej lwg taw tes kub thiab qis dua 80% txheeb ze av noo.
③Tom qab siv cov cuab yeej pleev xim, cov thinner yuav tsum tau muab ntxuav kom huv si kom tsis txhob yooj yim ntxuav tom qab kho.
④ Ua raws li kev ceev faj txog kev nyab xeeb uas tau teev tseg los ntawm cov kev cai hauv lub tebchaws.
5. Kev tshuaj xyuas
Cov khoom soj ntsuam yuav tsum tau ua tom qab tha xim yog raws li hauv qab no.
(1) Kev tshuaj xyuas saum npoo
Txhua qhov chaw yuav tsum tsis muaj hmoov av thiab chlorides tom qab siv cov xim.
(2) Kev tshuaj xyuas qhov muag
Cov xim txheej yuav tsum tsis tu ncua thiab tiaj tus, nrog cov xim sib xws, tsis muaj hlwv, tsis muaj qhov me me, tsis muaj khawb lossis tsis sib xws.
(3) Xim txheej thickness kuaj
Kev ntsuam xyuas cov yeeb yaj kiab ntub dej, txhua pawg ntawm cov li qub yuav tsum ua 3 pawg ntawm cov ntsuas tuab, txhua pab pawg ntsuas tus nqi ntawm 4 cov ntsiab lus, qhov nruab nrab ntawm 4 cov ntsiab lus nyeem yuav tsum tau ua raws li qhov tsawg kawg nkaus tus nqi ntawm cov tuab ntawm cov xim pleev xim. , thiab txhua qhov kev nyeem ntawv yuav tsum tsis pub tsawg dua 75% ntawm qhov tsawg kawg nkaus thickness. Qhuav zaj duab xis thickness kuaj nrog cov cuab yeej ntsuas tsis muaj kev puas tsuaj, ntsuas ntsuas yuav tsum tau ntsuas txhua 8 teev.
(4) Adhesion xeem
Ua ntej tshaj plaws, siv rab chais hniav los txiav ob qhov 15mm txiav rau hauv cov xim txheej, ob qhov kev txiav yuav tsum tau hla cov xim rau saum npoo ntawm cov hlau, thiab yog li 30 degree ntawm "X" zoo, thiab tom qab ntawd txhuam cov xim. Cov xim pleev xim rau ntawm kev sib tshuam ntawm rab chais hniav kom txog rau thaum cov hlau ntog, yog tias cov xim tev tawm ntawm qhov sib tshuam ntawm ntau tshaj "X Yog tias cov xim tev tawm ntawm qhov kev sib tshuam tshaj qhov "X" qhov pib (qhov "X" pib. yuav tsum yog 2 hli tshwj tsis yog txwv tsis pub los ntawm Demanding Party) lossis yog tias cov tev flakes tsis yooj yim, qhov kev ntsuam xyuas yuav tsum raug suav tias ua tsis tiav.Cov txheej txheej txheej yog honeycomb-puab uas ua rau txo qis adhesion ntawm cov xim txheej yog suav tias tsis tsim nyog.
(5) sampling xeem
Valve cov khoom, xim zoo tshuaj ntsuam sampling, raws li GB / T 2828.1 kev tshuaj xyuas qib.
(6) cov ntaub ntawv xeem
Cov neeg soj ntsuam xim yuav tsum sau "cov ntaub ntawv soj ntsuam xim" txhua hnub.
