Anti - Corrosion Steel Kav yog ib cov khoom siv tsis tau muaj nyob hauv kev lag luam niaj hnub thiab qhov txhab siv. Qhov zoo ntawm lawv cov txheej txheem kev tsim nyog ncaj qha txiav txim siab lawv txoj kev pabcuam lub neej thiab kev nyab xeeb. Raws li cov corrosion tsis kam yuav tsum rau cov raj roj hauv cov roj, roj, thiab cov tshuab corrosion (} Kab lus no yuav delve rau hauv cov txheej txheem tsim rau anti - Corrosion ntawm cov txheej txheem ntau lawm los ntawm cov txheej txheem yooj yim rau cov ntsiab lus yooj yim.
I. Kev tsim cov ntsiab cai ntawm ovi - corrosion steel kav
Anti - Corrosion Steel Kav Muaj cov qauv ntawm "cov khoom siv corrosion Cov hom phiaj tseem ceeb ntawm cov txheej txheem tsim no yog txhawm rau kom cov khoom siv hluav taws xob (xws li cov khoom siv corrosion (xws li cov tshuaj tiv thaiv corrosion (xws li cov pa dej siab, muaj zog acids, cov tshuaj tsuag alkalis).
Tso cai tso quav yeeb tshuaj ib zaug li ntawm ib lub tubular "Vuam" Isti {{6} Kev siv tshuab corrosion tsim raws li cov yeeb nkab uas ua rau cov yeeb nkab ntau ntxiv los ntawm kev kho cov yeeb nkab, txheej, lossis cladding.
Ii. Cov ncauj lus kom ntxaws piav qhia ntawm cov tub ntxhais tsim cov txheej txheem
1. Cov yeeb nkab yeeb nkab ua ntu zus: tu thiab sau
Daim ntawv cog lus sib cog lus ntawm anti - corrosion txheej thiab cov yeeb nkab corrosion thiab cov yeeb nkab steel nyob ncaj qha thiab roughness ntawm lub hauv paus yeeb cov nplaim dej nto. Yog tias cov roj uas seem, xeb, lossis anti {2} Cov khoom siv corrosion yuav tsis ua rau muaj teeb meem zoo xws li bulging thiab tev. Yog li ntawd, pretreatment yog thawj kauj ruam tseem ceeb hauv cov txheej txheem tsim.
Cov haujlwm tshwj xeeb suav nrog:
Cov cuab yeej siv kho kom muaj kev tshem tawm: Kev txhaj tshuaj tiv thaiv kev sib tsoo lossis kev tshem tawm cov nplai sib luag (feem ntau yuav tsum muaj lub thauj tog rau nkoj loj heev (feem ntau yuav tsum muaj lub nkoj dav hlau loj (chaw nres tsheb loj)
Tshuaj Tu: Organic kuab tshuaj (xws li acetone) yog siv los tshem tawm cov khoom siv tawm thiab muaj xeb me me, kom pom qhov ntev ntawm cov paug tsis muaj paug.
Kom qhuav: huab cua kub lossis infrared kom qhuav yog siv los tswj cov npoo av ntawm cov yeeb nkab steel rau qib qis (av noo<5%) to prevent bubbles during subsequent coating.
2. Anti {- corrosion txheej txheej: sib piv ntawm cov txheej txheem loj
Raws li hom anti - corrosion cov khoom thiab daim ntawv thov ntawm anti {1 s corrosion steel kav tuaj yeem muab faib ua peb qhov tseem ceeb:
(1) Peb {{-}}}}}) ov- corrosion {}} Cov txheej txheem siv dav tshaj plaws
3Pe anti {{{{1} pa corrosion yog ib qho qauv sib xyaw ntawm "Fusion Lorks Cov Khaub Ncaws epoxy (FUEETHENTAL Nruab Nrab Txheej + Polyethylene Txheej Txheej". Nws muab cov khoom zoo siab ntawm epoxy hmoov nrog ib puag ncig kev nyuaj siab tawg tsis kam ntawm polyethylene, thiab yog haum rau cov roj hnyav xws li cov roj faus thiab roj. Cov txheej txheem moulding yog raws li hauv qab no:
Cov Txheej Txheem Txheej Txheem: electrostatically tsuag fused loj epoxy hmoov (artring nws ntawm ib tug kub {{1} μm) ib yam.
Intermediate txheej txheej: cov nplaum nplaum (xws li hloov polyethylene copolymer) yog cov actees rau sab nraum lub puab epoxy los ntawm cov pwm, nrog ib qho tuab ntawm li 170-250 μm;
Txheej txheem extrusion: High - ntom polyethylene nrog ib qho tuab ntawm 1.8-3.7 hli (resistant rau ultraviolet rays thiab tshuab puas).
(2) epoxy thee tar - corrosion- - streter txoj kab uas hla
Cov txheej txheem no siv Epoxy Resin thiab ntim rau cov khoom siv raw lub ntsiab, thiab ua cov tshuaj tiv thaiv corrosion nyob rau saum npoo ntawm cov yeeb nkab ntawm cov hlau nplaum los ntawm txhuam hniav lossis ntsw txhuam hniav. Nws cov yam ntxwv yog tus nqi tsawg, tab sis nws yog nkag siab txog kev tsim kho kub (yuav tsum muaj ntau dua 5 degree) thiab feem ntau siv rau cov dej xau thiab dej paug lossis ib qho dej paug.
(3) Cug Cug Cug Hauv Cled Al ...-}} Ib qho kev daws teeb meem ntxiv rau cov xwm txheej tshwj xeeb
Rau tsawg -} pa taws uas tsis {{{{} {} {} Cov pa dej khov (xws li cov yeeb nkab hauv phab ntsa hauv phab ntsa 10 {- 30mm. Cov txheej txheem no yog tus nqi qis thiab hnav-resistant, tab sis tau tsis muaj zog tiv taus tshuaj corrosion.
3. Post {{{{{{{}} kev thiab kuaj: ua kom zoo ua cov khoom zoo
Tom qab sib sau, anti - corrosion txheej indergoes undergoes nruj heev tswj:
Thickness ntsuas: Ntsuas cov tuab ntawm txhua txheej lossis ultrasonic tuab txheej txheem yuav tsum muaj ntau dua lossis sib npaug ntawm 80μm, thiab cov polyethylene txheej yuav tsum loj dua lossis sib npaug ntawm 2 hli).
Adhesion kuaj: Tshawb xyuas lub zog ntawm cov anti {{0} {daug lossis rub tawm txoj kev (sib npaug nrog 5mpa).
Kev soj ntsuam hluav taws xob hluav taws xob tau txais: scan saum npoo ntawm anti- cov khoom siv corrosion nrog lub siab {2} {}} Tsom-{
Cov tsos tshuaj xyuas: Tshawb xyuas qhov tsis muaj qhov tsis xws luag xws li npuas, kab nrib pleb, thiab sensuring ib tug du thiab txawm saum npoo.
III. Ua cov qauv tshiab thiab yav tom ntej
Nrog kev nce qib ntawm kev thov kev lag luam, cov txheej txheem tsim rau corrosion - Cov thev naus laus zis tiv taus ntau ntxiv, kev ua phooj ywg ntse, thiab ib puag ncig cov thev naus laus zis:
Kev Txhawb Nqa Kev Ua Haujlwm: Nrig cov yeeb nkab txuas ua ke "steel yeeb nkab dov, thiab anti {{{} corrosion unating," shortening kycles thiab txhim kho kev sib xws;
Kev loj hlob tshiab ovi - cov ntaub ntawv corrosion: cov ntawv thov xws li lub neej corrosion (txog 50 xyoo lossis ntau dua);
Kev tshawb nrhiav ntawm cov txheej txheem ntsuab: txo kev siv cov organic cov kuab tshuaj (piv txwv li hloov cov txheej txheem {}
Tag
Cov txheej txheem tsim rau corrosion - tiv taus steel kav yog ib qho kev sib tshuam ntawm cov ntaub ntawv science, kev tsim khoom siv me nyuam, thiab tshuaj kho tshuab, thiab tshuaj kho tshuab, thiab tshuaj kho tshuab. Los ntawm cov yeeb nkab cov khoom ua piv txwv rau daim ntawv thov kom meej ntawm ove- corrosion txheej, txhua kauj ruam yuav tsum tau tswj ruaj khov ntawm cov tsis muaj kev ntsuas thiab cov ntsiab lus. Nrog kev txhim kho thev naus laus zis txuas ntxiv, xws li kev tsim kho ntawm corrosion) thiab tseem ua tiav kev txhawb nqa ntawm kev tsim kho ntiaj teb rau kev tsim kho thoob ntiaj teb.
