Qhov ntev koj siv cov cam khwb cia hlau manhole npog, qhov teeb meem ntau koj yuav muaj.Yog li ntawd, txhawm rau daws cov teeb meem no, koj thawj zaug yuav tsum paub yuav ua li cas nrog lawv thiab yuav kho lawv li cas.Hnub no kuv yuav nrog lawv tham.Cia peb tham txog tej teeb meem yav tom ntej.Yuav ua li cas yog tias kuv cov khoom yog xeb?Kawm los ntawm cov kws kho ntawm Xinsheng Plumbing yog vim li cas ductile cam khwb cia hlau manhole npog xeb thiab kev daws teeb meem.
1. Yog vim li cas ductile cam khwb cia hlau manhole npog xeb:
1. Oxidation ntawm manhole npog
Ductile cam khwb cia hlau yog ntsia sab nraum zoov.Qhov no yog cov txheej txheem oxidation ib txwm rau spheroidal graphite cam khwb cia hlau.Thaum ib txheej oxide tsim rau ntawm qhov chaw, nws tsis nkag mus rau hauv.Cov oxide txheej yog cais tawm ntawm huab cua thiab tsis xeb.Thaum kawg, cov hlau cam khwb cia hlau tsis xeb zoo li hlau, thiab xeb tawm ntawm txheej los ntawm txheej.
2. Chloride ions muaj nyob rau hauv qhov chaw ua hauj lwm ntawm lub manhole npog
Chloride ions xws li ntsev, hws thiab dej hiav txwv tau dav siv.Lub xub ntiag ntawm chloride ions ua rau corrosion sai dua li cov hlau me me.Yog li ntawd, muaj cov kev cai rau lub manhole npog siv ib puag ncig, uas yuav tsum tau wiped nquag kom tshem tawm cov plua plav thiab kom nws huv si thiab qhuav.
3. Tsis muaj tshuaj kho
Txij li thaum alloying ntsiab tsis yaj nyob rau hauv lub matrix, cov ntsiab lus alloy ntawm lub matrix qauv yog tsawg thiab corrosion kuj yog txo.Yog li ntawd, txhua tus neeg yuav tsum tau ua tib zoo saib xyuas cov kev tiv thaiv hauv qhov no.
4. Manhole npog yog ib txwm corroded los ntawm grain ciam teb
Qhov no titanium- thiab niobium-dawb cov ntaub ntawv yog nquag mus rau intergranular corrosion.Ntxiv titanium thiab niobium nrog rau kev kho kom ruaj khov tuaj yeem txo cov kev cuam tshuam ntawm intergranular.High alloy steel resistant rau atmospheric thiab tshuaj corrosive media.Yog li dab tsi yog qhov kev daws teeb meem rau rusting ductile cam khwb cia hlau manhole npog?
Thib ob, yuav ua li cas tshem tawm xeb los ntawm cov hlau cam khwb cia hlau manhole npog:
1. Txau xeb tshem tawm
Cov cua compressed npaj los ntawm cov roj-dej sib cais ua rau cov abrasive raug tshem tawm ntawm lub nozzle ntawm kev kub ceev, thiab cov huab cua thiab lub manhole npog yog tag nrho scraped tawm.Tam sim ntawd huv si, compressed cua siab yog feem ntau 4-0.6Mpa, thiab high-speed pressed nceb hu rau lub ductile cam khwb cia hlau manhole npog kom tshem tawm oxide nplai thiab xeb, ua rau kev sib txhuam thiab kev cuam tshuam.nce.Cov qauv no tsis tas yuav tsum tau muaj txoj haujlwm ruaj khov, muaj qhov ua tau zoo ntawm qhov chaw txhaj tshuaj, kev hloov pauv siab, tsis muaj qhov muag tsis pom kev, qhov zoo ntawm lub pas dej tshem tawm, thiab tib lub sijhawm muab qee qhov roughness rau saum npoo thiab ua raws li cov yeeb yaj kiab zaj duab xis.txhawb nws.Koj yuav tsum siv txoj kev.
2. Tshem tawm xeb ntawm qhov projectile
Kev kub ceev rotating impeller ntawm lub tshuab moj tej tawg yog siv los disperse lub moj tej tawg nruab nrab ntawm nws nto, uas pops tawm ntawm kev kub ceev thiab rubs tawm tsam ntawm lub ductile cam khwb cia hlau manhole npog.Txhawm rau tshem tawm cov xeb thiab oxide nplai, cov txheej txheem no ua haujlwm tau zoo thiab muaj cov xeb tshem tawm zoo heev, ua tiav qee qhov roughness ntawm qhov chaw thiab txhawb nqa cov adhesion ntawm zaj duab xis zaj duab xis, ua haujlwm.Nws txo qis kev siv zog thiab txo cov teeb pom kev zoo rau ib puag ncig.Yog siab, qhov zoo ntawm kev tshem tawm xeb yog qhov zoo, thiab kev tsim cov neeg ua haujlwm siab tau txo qis me ntsis.Yog li ntawd, nyob rau hauv dav dav, loj manufacturers siv txoj kev no los tshem tawm xeb.
Cov saum toj no yog ib qho kev qhia txog cov laj thawj thiab kev daws teeb meem rau rusting ductile cam khwb cia hlau manhole npog, tab sis cov no yog ob txoj kev kho mob tshwj xeeb, thiab cov kev kho mob uas tau maj mam nce hauv kev siv yuav tsis zoo ib yam.Txawm hais tias koj siv txoj kev tiv thaiv xeb twg, muaj kev pheej hmoo hauv kev ua haujlwm, yog li tsa koj txoj kev paub txog kev nyab xeeb thiab xyuas kom koj muaj kev nyab xeeb thaum ua haujlwm.Muaj lwm yam kev lag luam tiam sis muaj feem xyuam rau cov ductile manhole npog.https://www.lxcover.com/contact-us/
