Hauv ntau thaj chaw xws li roj av, tshuaj lom neeg, thiab cov khoom siv dej thiab cov kav dej, tiv thaiv -corrosion steel kav yog cov khoom tseem ceeb ntawm cov yeeb nkab uas ua kom lub sijhawm ntev - lub sijhawm ua haujlwm ruaj khov ntawm kev thauj mus los. Cov txheej, raws li tus yuam sij rau nws txoj kev tiv thaiv corrosion, ncaj qha txiav txim siab txog kev pabcuam lub neej thiab kev nyab xeeb ntawm cov yeeb nkab steel.
Epoxy coal tar txheej yog ib txwm siv thiab siv los tiv thaiv - xaiv corrosion. Nws yog tsim los ntawm epoxy resin thiab thee tar, combining lub zog nplaum ntawm epoxy resin nrog corrosion kuj ntawm thee tar. Cov txheej yog tuab heev, zoo cais tawm corrosive hauv dej thiab av. Nws muaj kev cuam tshuam zoo heev thiab kev puas tsuaj, ua rau nws haum rau qhov hnyav ib puag ncig xws li faus thiab hauv qab dej. Cov txheej txheem kev tsim kho yog paub tab thiab tus nqi nruab nrab. Nws yog feem ntau siv rau kev tiv thaiv kev tiv thaiv sab nraud ntawm cov dej hauv nroog thiab cov kav dej thiab cov roj thiab cov kav dej. Txawm li cas los xij, nws cov huab cua tsis kam yog qhov tsis muaj zog; Nws yog nquag mus rau kev laus thaum raug tshav ntuj rau ncua sij hawm. Rau kev siv sab nraum zoov, yuav tsum muaj txheej tiv thaiv.
3PE txheej (peb- txheej polyethylene txheej) tam sim no yog qhov kev xaiv tseem ceeb hauv kev tiv thaiv- teb. Nws muaj cov qauv sib xyaw ntawm cov txheej hauv qab ntawm epoxy hmoov, txheej nruab nrab ntawm cov nplaum, thiab txheej txheej ntawm polyethylene. Cov txheej hauv qab ntawm epoxy hmoov adheres nruj rau cov yeeb nkab steel nto nrog adhesion muaj zog heev; nruab nrab txheej ntawm cov nplaum ua kom muaj kev ruaj khov ntawm ob txheej txheej; Cov txheej txheej ntawm polyethylene muaj cov huab cua zoo heev, tshuaj tiv thaiv corrosion, thiab UV tsis kam. Cov txheej no muaj kev ua tau zoo tag nrho, kev pabcuam lub neej txog li ob peb xyoos, thiab tuaj yeem hloov mus rau ntau qhov chaw xws li av, dej hiav txwv, thiab tshuaj lom neeg. Nws yog dav siv nyob rau hauv siab -kawg tej yaam num xws li ntev - roj thiab roj tsheb thauj mus los thiab tob - hiav txwv pipelines. Txawm li cas los xij, nws yuav tsum tau siv cov cuab yeej siv kho kom zoo thiab muaj tus nqi siab.
Epoxy hmoov txheej siv epoxy resin ua nws cov khoom tseem ceeb thiab yog tsim los ntawm electrostatic txau thiab kho. Nws yog ib qho hnyav -dawb txheej nrog zoo ib puag ncig tus phooj ywg. Nws muaj zog heev adhesion rau steel yeeb nkab nto, ib tug zoo li thiab tuab txheej, zoo heev tshuaj corrosion kuj thiab puas kuj, thiab yog ib qho yooj yim mus thov thiab kho sai, ua rau nws haum rau ob sab hauv thiab sab nraud corrosion tiv thaiv ntawm pipelines. Cov txheej no muaj qhov kub thiab txias ntau, siv tau nyob rau hauv ib puag ncig ntawm -50℃txog 120 degree, thiab haum rau cov kav dej tshuaj, cov kav dej kub kub thauj mus los, thiab lwm yam. Txawm li cas los xij, nws cov huab cua tsis kam tsuas yog qhov nruab nrab, thiab kev tiv thaiv yuav tsum tau siv rau sab nraum zoov.
Hauv cov ntsiab lus, kev xaiv los tiv thaiv -corrosion steel yeeb nkab txheej yuav tsum xav txog ib puag ncig kev hloov pauv, tiv thaiv- cov kev xav tau corrosion, thiab cov nqi siv nyiaj: 3PE txheej yog nyiam rau siab -kawg tej yaam num, epoxy coal tar coatings yog haum rau cov pa faus pipelines, thiab epoxy hmoov txheej yog tsim nyog rau high-temperature kev siv tshuaj lom neeg. Xaiv cov txheej txheej zoo tuaj yeem ua rau lub neej ua haujlwm siab tshaj plaws ntawm cov kav dej steel thiab txo cov nqi tu qhov project.
