Lub teeb-kho prepreg tsis tsuas yog muaj kev tsim kho kom zoo, tab sis kuj muaj kev tiv thaiv zoo rau cov kua qaub, alkalis, ntsev thiab cov kuab tshuaj organic, nrog rau cov neeg kho tshuab zoo tom qab kho, zoo li FRP tsoos.Cov khoom zoo heev no ua rau lub teeb-kho tau prepregs haum rau tshuaj, roj av cia tso tsheb hlau luam, cov kav dej hauv av thiab hauv av, thiab lwm yam, los tsim cov khoom siv tiv thaiv corrosion nrog kev ua tau zoo heev.
1. Daim ntawv thov kev tiv thaiv corrosion ntawm cov roj cia tank
Piv nrog rau kev kho cov txheej txheem ntawm kev sib cuag molding hauv ob sab phlu, vim hais tias lub teeb-kho prepreg tuaj yeem prefabricated rau hauv cov nplooj ntawv los yog yob, thiab muaj cov yeeb yaj kiab yas nyob rau sab saud thiab qis, qhov hnyav volatilization thaum lub sij hawm tsim kho yog me me, uas zoo heev txhim kho kev tsim kho. ib puag ncig thiab kev nyab xeeb.poj niam deev.Lub teeb tsis kho lub teeb-kho prepreg yog mos thiab tuaj yeem txiav lossis txiav raws li qhov xav tau ntawm qhov project thiab tom qab ntawd thov ncaj qha.Nws yog kho los ntawm UV teeb.Lub sijhawm kho tsuas yog 10 mus rau 20 feeb.Nws tsis tshua cuam tshuam los ntawm ib puag ncig thiab tuaj yeem siv tau txhua xyoo puag ncig.Kev tsim kho, tuaj yeem muab tso rau hauv kev siv tam sim tom qab kho, txo lub sijhawm tsim kho thiab cov nqi zog.
Ntawm PetroChina Chongming No. 3 chaw nres tsheb roj, lub teeb-kho prepreg npaj los ntawm MERICAN 9505 tau siv los kho lub hauv ob sab ntawm cov roj cia tank.Cov xwm txheej kev tsim kho muaj nyob hauv daim duab hauv qab no.Lub hardness tuaj yeem ncav cuag 60, thiab nws muaj qhov zoo corrosion kuj.
2. Anti-corrosion daim ntawv thov nyob rau hauv directional drilling pipeline
Directional Drilling yog cov txheej txheem kev tsim kho kav dej hauv kev lag luam thev naus laus zis engineering.Nws yog dav siv nyob rau hauv kev tsim kho cov roj, natural gas thiab ib co municipal pipelines.Yuav ua li cas los tiv thaiv corrosion sab nrauv sheath thaum lub sij hawm pipeline directional drilling yeej ib txwm yog ib qho teeb meem nyuaj nyob rau hauv lub teb ntawm pipeline kev tsim kho..Feem ntau ntawm cov kav dej hloov pauv tau siv nyob rau hauv kev taw qhia drilling hla, thiab qhov nyuaj ntawm cov txheej txheem tiv thaiv corrosion ntawm qhov chaw ntawm cov yeeb nkab lub cev tsis txaus.Thaum lub sij hawm tus txheej txheem rub, cov txheej txheem tiv thaiv corrosion feem ntau tawg los yog ntug ntawm cov khoom siv patching yog warped los yog tawg, uas cuam tshuam rau cov nyhuv anti-corrosion thiab ua rau muaj kev phom sij rau kev nyab xeeb ntawm cov kav dej.Nyob rau hauv kev saib ntawm cov teeb meem saum toj no, lub teeb-kho prepreg tuaj yeem siv los ua cov txheej txheem tiv thaiv ntawm txheej txheej ntawm cov kav dej.Nws cov yam ntxwv tseem ceeb yog siab hardness, khawb kuj thiab kev sib txhuam tsis kam, uas tuaj yeem tiv thaiv cov txheej txheem tiv thaiv corrosion.
Kev sib piv ntawm lub teeb-kho lub tes tsho tiv thaiv ua ntej thiab tom qab siv cov kev taw qhia drilling pipeline yog qhia hauv daim duab hauv qab no:
Nws tuaj yeem pom tseeb los ntawm kev sib piv tias lub teeb-kho prepreg txheej muaj kev tiv thaiv zoo ntawm cov kav dej thiab txhim kho cov kev ua haujlwm tiv thaiv corrosion ntawm cov kav dej.
3. Anti-corrosion daim ntawv thov ntawm cov roj thiab roj cia tank ru tsev
Feem ntau ntawm cov roj thiab roj cia tank yog steel hlau tank.Vim tias cov roj thiab roj feem ntau muaj cov tshuaj corrosive, corrosion ntawm hlau tso tsheb hlau luam yog qhov hnyav heev.Piv txwv li, nyob rau hauv qhov kev txiav txim ntawm kub siab nyob rau hauv lub tank, cov teeb meem gases xws li yaj oxygen, hydrogen sulfide thiab carbon dioxide yuav volatilize thiab ua rau muaj zog corrosion nyob rau sab saum toj ntawm lub tank, ua rau muaj kev puas tsuaj loj rau sab saum toj ntawm lub tank. tsis tsuas yog ua rau cov roj loj loj thiab roj poob, tab sis kuj nce kev nyab xeeb.zais kev phom sij.Rau kev nyab xeeb ntawm kev siv roj thiab roj tso tsheb hlau luam, kev saib xyuas hauv zos lossis hloov lub tank sab saum toj yog xav tau ntau zaus.Cov txheej txheem ntawm kev kho lub ru tsev tank yog hloov cov hlau tank ru tsev steel phaj, uas yuav tsum tau lub tank yuav tsum tau nres, huv si, chav tsev tsim los tsim kev ntsuas kev nyab xeeb, thiab lub chaw saib xyuas kev nyab xeeb kom pom zoo cov txheej txheem los ntawm txheej.Lub sijhawm tsim kho yog ntev thiab cov nqi kho mob siab.Txawm li cas los xij, siv lub teeb-kho prepreg, lub tank sab saum toj uas twb muaj lawm yog siv los ua tus qauv, thiab nws tau tsim thiab txiav rau ntawm qhov chaw, thiab nws tau sib koom nrog cov hlau qub tank saum toj kawg nkaus.Raws li kev tswj hwm tus thawj lub tank sab saum toj lub zog, lub zog ntawm cov txheej txheem sib xyaw yog sib npaug thiab tuaj yeem siv los ua cov kev daws teeb meem tshiab rau lub ru tsev kho cov roj thiab roj tso tsheb hlau luam.
Ntxiv nrog rau cov lus hais saum toj no los tiv thaiv corrosion, lub teeb-kho prepregs kuj tseem siv tau rau hauv thaj chaw tiv thaiv corrosion xws li cov pas dej ua ke hauv cov chaw hauv av, cov kav dej hauv av, cov tso tsheb hlau luam hauv cov khib nyiab pov tseg, nkoj decks, thiab kev kho vaj tse fais fab.Tam sim no, feem ntau ntawm lub teeb-kho cov ntawv prepreg nyob rau hauv kev ua lag luam yog cov khoom tuaj txawv teb chaws, thiab tus nqi yog siab, uas txwv lawv daim ntawv thov.Txawm li cas los xij, nrog kev txhawb nqa ntawm lub xeev, kev saib xyuas ntawm kev ua lag luam, thiab kev nqis peev ntau ntxiv ntawm kev tshawb fawb thiab kev tsim kho cov peev txheej, yuav muaj ntau thiab ntau ntau hom kev siv hluav taws xob kho hluav taws xob hauv tsev prepreg siv nyob rau hauv ntau qhov chaw.
