Anti-corrosion steel yeeb nkab yog hais txog cov txheej txheem los tiv thaiv corrosion, tuaj yeem tiv thaiv kom tsis txhob muaj kev cuam tshuam los yog qeeb hauv kev thauj mus los thiab siv cov tshuaj lom neeg lossis cov tshuaj electrochemical tshwm sim nyob rau hauv corrosion phenomenon ntawm steel kav. Anti-corrosion steel yeeb nkab tuaj yeem tiv thaiv kom tsis txhob muaj kev cuam tshuam los yog qeeb qeeb kom ntev kev pab cuam lub neej ntawm cov yeeb nkab steel, txo cov nqi khiav lag luam ntawm cov yeeb nkab steel.
Daim ntawv thov ntawm ntau cov yeeb nkab steel tiv thaiv txheej txheej muaj roj av asphalt, PE tsho thiab PE ua npuas ncauj tsho, epoxy thee asphalt, thee tar enamel, epoxy hmoov thiab peb-txheej cov qauv, epoxy coal asphalt txias qhwv daim kab xev (PF-type), roj hmab-yas epoxy coal asphalt txias-wrapped daim kab xev (RPC-hom), thiab yog tam sim no txhawb kev siv ntawm cov feem ntau lug siv ob peb hom pipeline anticorrosive txoj kev rau peb-txheej PE composite qauv, ib txheej ntawm hmoov epoxy, PF-hom txias-pob daim kab xev, RPC hom txias qhwv daim kab xev.
- Petroleum asphalt, raw khoom, tus nqi qis. Tab sis kev ua haujlwm tsis zoo, qhov ua tau zoo yog qhov nyuaj los xyuas kom meej, muaj kuab paug ib puag ncig loj.
- Epoxy thee asphalt, yooj yim rau kev khiav lag luam, tab sis lub npog txheej kho lub sij hawm ntev, cuam tshuam los ntawm ib puag ncig, tsis haum rau kev ua haujlwm, 10 degree hauv qab qhov kev tsim kho nyuaj.
- Epoxy hmoov anticorrosion, siv electrostatic txau, nrog tib cov khoom siv los tiv thaiv corrosion ntawm cov yeeb nkab lub cev fusion yog qhov zoo, muaj zog adhesion, tab sis epoxy hmoov waterproofing tsis zoo (siab dej nqus tus nqi, mus txog 0.83%), mus rau cathodic tiv thaiv tsim coj ib co teeb meem. Cov kev xav tau siab rau cov cuab yeej siv hauv teb, kev ua haujlwm nyuaj, qhov zoo tsis yooj yim rau kev tswj.
- 3PE tshav kub-shrinkable cov ntaub ntawv, pipeline anticorrosive sealing, siab mechanical zog, waterproof, ruaj khov zoo, yooj yim siv, zoo applicability, tsis muaj kuab paug ib puag ncig. Cov dej nqus dej tsawg ntawm PE (tsawg dua 0.01%), tib lub sijhawm, nrog lub zog siab ntawm epoxy, tsis tshua muaj dej nqus ntawm PE thiab kub-melt nplaum nplaum, thiab lwm yam, muaj cov qib siab ntawm anticorrosive kev ntseeg siab, qhov tsis zoo: piv nrog rau lwm cov khoom siv kho mob, tus nqi siab.
- PF-hom, RPC-hom txias wrapping daim kab xev siv tau yooj yim thiab yooj yim, txhawb nqa peb hom stereotypes ntawm cov nplaum, kom PF-type epoxy-coal asphalt txias wrapping daim kab xev tuaj yeem nyob hauv ib puag ncig, txhua lub caij, txhua qhov kub thiab txias. ntawm kev tsim kho.
- Txias wrapping daim kab xev thiab 3PE tshav kub shrinkable daim kab xev yog tus cwj pwm los ntawm: muaj feem xyuam rau ntau yam ntaub ntawv, lub ntsiab lub cev ntawm anti-corrosion txheej pipeline, thaum lwm txoj kev yog muaj feem xyuam rau tib yam los yog ze rau cov khoom ntawm lub ntsiab lub cev. anti-corrosion txheej pipeline.
Thib ob, nrog rau kev txhim kho ntawm qee cov kav dej hauv kev tiv thaiv corrosion tib lub sijhawm kuj xav tau thermal rwb thaiv tsev, roj yog qhov sib xyaw ua ke, yooj yim rau corrode lub raj xa dej, kev tiv thaiv corrosion yog qhov tsim nyog, tab sis cov roj refined pipeline nyob rau hauv rooj plaub. anti-corrosion kuj yuav tsum tau ua thermal rwb thaiv tsev, nyob rau hauv Northeast thiab nyob rau hauv lub caij ntuj no, lub thermal expansion thiab contraction yuav khov thiab tawg raj, cuam tshuam rau stability ntawm mov.
