Cov yeeb nkab steel anticorrosive txheej siv ntau thiab ntau cov ntaub ntawv sib xyaw lossis cov qauv sib xyaw. Cov ntaub ntawv thiab cov qauv no yuav tsum muaj qhov zoo dielectric, physics, chemistry, thiab qhov kub thiab txias adaptability.
Polyethylene tsis muaj ntxhiab tsw, tsis muaj tshuaj lom, waxy, thiab muaj qhov kub thiab txias tsis zoo (qhov tsawg kawg nkaus ua haujlwm kub tuaj yeem ncav cuag -70 ~ -100 ° C), tshuaj lom neeg ruaj khov, thiab tuaj yeem tiv taus feem ntau ntawm cov kua qaub thiab alkali corrosion (anaerobic acid). Nws yog insoluble nyob rau hauv nruab nrab hnyav ntawm chav tsev kub, thiab cov dej nqus tus nqi yog tsawg, tab sis vim hais tias nws yog ib tug linear molecule, nws yog yaj maj mam yaj, thiab nws tsis o nyob rau hauv tej yam organic solvents, yog li nws muaj zoo heev hluav taws xob rwb thaiv tsev kev ua tau zoo.
Sab nrauv phab ntsa anticorrosive txheej: hom thiab daim ntawv thov ntawm txheej phab ntsa txheej ntawm cov kav dej.
Sab hauv phab ntsa los tiv thaiv-antichematic txheej: Txhawm rau tiv thaiv corrosion hauv cov kav dej, txo kev sib txhuam, thiab txhim kho cov peev txheej ntau lawm, thov ib txheej ntawm zaj duab xis rau sab hauv phab ntsa ntawm cov kav dej. Cov txheej txheem muaj xws li amine khoom epoxy resin thiab polyamide epoxy resin. Lub thickness ntawm txheej yog 0 038-0.2 hli. Txhawm rau kom ntseeg tau tias cov txheej txheem thiab cov phab ntsa ntawm lub raj yog ruaj khov, cov phab ntsa sab hauv ntawm lub raj yuav tsum tau ua tiav. Txij li thaum xyoo 1970s, cov txheej txheem anticorrosive ntawm cov phab ntsa sab nrauv ntawm cov yeeb nkab steel tau xaiv cov xim tib yam, txawm tias nws yog nyob hauv tsev lossis txawv teb chaws, uas tau ua rau cov txheej txheem no muaj kev tiv thaiv corrosion ntawm cov kav hlau.
Anti-corrosion steel yeeb nkab rwb thaiv tsev txheej: Yuav kom txo tau cov cua kub dissipation ntawm nruab nrab thiab me-caliber tshav kub conductive roj los yog roj pipeline av, cov kev noj nyiaj txiag composite txheej yog teem rau sab nraum lub raj xa dej. Cov khoom siv rwb thaiv tsev feem ntau yog ib qho tawv polyurethane ua npuas ncauj nrog qhov kub ntawm -185 ~ 95 degrees. Qhov kev ntxhib los mos ntawm cov khoom no yog mos. Txhawm rau txhim kho nws lub zog, ib txheej ntawm high-density polyethylene yog coated rau ntawm thermal rwb thaiv tsev txheej los ua ib qho kev sib xyaw ua ke los tiv thaiv cov dej hauv av los ntawm kev nkag mus rau hauv txheej rwb thaiv tsev.
