Lub cev yog qhov feem tseem ceeb, "lub cev pob txha" ntawm lub tsheb. Nws yog ib qho tseem ceeb tiv thaiv lub cev tsheb los ntawm kev puas tsuaj thiab xeb. Nrog rau thawj zaug, txhua yam muaj tseeb heev, tab sis lub thib ob tau muaj kev sib cav rau ntau xyoo.
Ua rau thiab thaj chaw tiv thaiv xeb
Txoj kev xeb nws tus kheej yog qhov yooj yim heev. Qhov no yog qhov oxidation ntawm hlau thaum cuam tshuam rau huab cua thiab dej. Raws li, qhov muaj kev ntxim nyiam tshaj plaws yog xeb yog cov ntu ntawm lub tsheb uas tau chwv nrog ob yam khoom no tib lub sijhawm.
Ib daim ntawv luv luv ntawm cov corroded lub cev feem ntau.
- log arches;
- ntu ntawm seem hauv qab uas tau nyob tam sim tom qab ntawm lub log;
- spars.
- sab hauv ntu ntawm qhov pib;
- racks;
- sab hauv qis ntawm qhov rooj;
- log arches.
- hlau, uas yog nyob tom qab lub qhov rooj ntawm lub qhov rooj, pob tw, lub kaus mom;
- txhob txhaws;
- qis qis ntawm lub qhov rooj;
- cov kab noj hniav zais hauv qab cov nqaj, chaw ua haujlwm;
- sab xub ntiag ntawm lub hood.
Xeb tuaj yeem tuaj yeem tshwm sim ntawm cov xim pleev xim (cov tawv me).
Cov hau kev rau kev tiv thaiv xeb ntawm lub tsheb
Txhua ntu ntawm lub tsheb nws muaj nws tus kheej los tiv thaiv xeb.
Lub ntsiab ntawm lub tsheb yog pleev xim rau hauv cov xim pleev xim rau qee yam xim, uas yuav tsum tiv thaiv qhov tseem ceeb ntawm cov khoom lag luam hlau los ntawm kev xeb. Rau qhov ua haujlwm kom raug ntawm no los tiv thaiv corrosion txheej, nws yog ib qho tsim nyog los tiv thaiv nws kom ntau li ntau tau los ntawm kev puas tsuaj. Tab sis yog tias cov xim pleev xim raug puas tsuaj, nws yog qhov yuav tsum tau pleev xim dua lub nti nrog lub pob tshwj xeeb xaum. Yog tias qhov kev puas tsuaj loj heev (kev sib tsoo), tom qab ntawd yuav tsum ua tiav qhov tsis ua rov qab.
Muaj ntau qhov chaw ntawm cov xim cia li yuav tsis pab tswj kom muaj kev ncaj ncees ntawm lub cev, lossis muaj ntau qhov chaw uas tsis tuaj yeem pleev xim. Cov chaw zoo li no tau tsim los ntxiv rau.
Hauv qab ntawm lub tsheb tau kho nrog ib yam khoom hu ua mastic. Nws muaj li ntawm kev sib xyaw ntawm cov cob thiab bitumen. Qee zaum corrosion inhibitors thiab dyes tau ntxiv rau nws, kuj yog qee yam lwm yam tshuaj ntawm kev txiav txim siab ntawm tus tsim khoom. Xws li cov txheej txheem tuaj yeem siv nrog txhuam los yog daim nyias nyias, tab sis feem ntau cov txheej txheem ntawm thov txheej nrog rab phom txau yog siv. Koj tseem tuaj yeem yuav cov tshuaj zoo li hauv poom.
Sab hauv lub tsheb tsis tau kho thiab xav tau kev kho xeb ntxiv. Txog kev kho cov kab noj hniav zoo li no, siv cov tshuaj tiv thaiv kab mob ua kua, uas nrov npe hu ua "Movil". Hauv qee qhov chaw (lawv tau qhia los ntawm lub tuam txhab tsim cov tsheb) qhov yog qhov, thiab siv rab phom txau tshwj xeeb nrog lub tog raj siv tau yooj yim thiab cov tshuaj tsuag tom kawg, lawv tau siv rau hauv cov kab noj hniav sab hauv. Txog kev yooj yim, koj tuaj yeem siv lub koob yees duab mini. Tom qab cov txheej txheem, cov qhov yog ntsaws nrog cov kaus mom roj hmab tshwj xeeb, uas tau muag hauv cov tsheb muag khoom.
Yuav ua li cas yog tias kev xeb twb tau pib lawm
Yog tias xeb tau pib rau hauv qee qhov chaw, tom qab ntawd qhov kev daws teeb meem zoo tshaj plaws yog kom tshem nws thiab siv cov txheej txheem tshiab los tiv thaiv corrosion. Txhawm rau ua qhov no, siv lub hau ntswj ntsia hlau, daim tawv me ntsia hlau los yog lwm yam cuab yeej ntse kom tshem tawm cov tshuaj tiv thaiv rau ntawm qhov chaw ntawm xeb thiab nyob ze nws. Tom ntej no, siv ntaub nplaum, koj yuav tsum ntxuav tawm cov xeb txhawm rau ntxuav hlau. Txo nrawm nrawm, koj tuaj yeem siv lub kaum ntsej muag sib tsoo los yog lub tshuab hluav taws xob nrog rau cov ntawv tsim nyog. Tom qab ntawd, siv lub xeb hloov pauv rau thaj tsam no thiab tos 2-3 teev. Tom qab ntawd yaug nws nrog dej, degrease saum npoo thiab siv txheej txheej tshiab ntawm txheej los tiv thaiv xeb (pleev xim lossis mastic).
