Los ntawm qhov kev xav ntawm txheej txheej kub, epoxy hmoov txheej thiab polyurea los tiv thaiv corrosion txheej yuav siv tau ib txwm nyob rau hauv cov av corrosion ib puag ncig xws li -30 ° C lossis -25 ° C mus rau 100 ° C, thaum peb txheej txheej polyethylene. Qhov siab tshaj plaws kev pabcuam kub ntawm cov txheej tiv thaiv corrosion yog 70 ℃. Nyob rau hauv cov nqe lus ntawm txheej thickness, tshwj tsis yog rau ob epoxy hmoov txheej, lub thickness ntawm lwm yam peb txheej yog tag nrho saum toj no 1 hli, uas yuav tsum tau muab faib mus rau hauv qeb ntawm tuab txheej.
Ib qho ntawm cov khoom siv dav dav ntawm cov txheej txheem txheej txheem yog cov khoom siv kho tshuab thiab lub cev ntawm cov txheej txheem, uas yog, qhov xwm txheej tiag tiag uas yuav raug ntsib hauv cov txheej txheem kev tsim cov kav dej, xws li xav txog kev khoov ntawm cov kav dej tom qab vuam thiab hoisting qis dua. ditch thaum lub sij hawm tsim kho cov kav dej ntev. Cov khoom uas tsis tshua muaj kub dabtsi yog khoov qhov ntsuas yog tsim raws li qhov sib txawv ntawm cov yeeb nkab diameters, qhov cuam tshuam cov khoom ntawm cov txheej yog txiav txim siab los ntawm kev sib tsoo puas tsuaj los ntawm kev thauj mus los ntawm cov kav dej thiab cov khoom siv rov qab, qhov khawb tsis kam thiab khawb tsis kam ntawm cov txheej yog txiav txim siab los ntawm khawb thiab abrasions thaum cov kav dej tau hla. Hnav tsis kam, thiab lwm yam Los ntawm qhov kev xav ntawm cov khoom no, tsis muaj teeb meem epoxy hmoov txheej, peb txheej txheej los yog polyurea txheej, lawv txhua tus muaj kev ua tau zoo, tab sis nyob rau hauv cov nqe lus ntawm txheej thickness, peb-txheej polyethylene muaj qhov zoo tshaj plaws cuam tshuam tus nqi, thaum txau Qhov tsawg kawg nkaus cuam tshuam tus nqi ntawm 14.7J rau polyurea tiv thaiv txheej kuj zoo heev.

Txij li thaum txheej txheej ntawm cov kav dej ntev ntev feem ntau yog siv nrog kev tiv thaiv cathodic, tsim ntawmpipeline txheejCov ntsuas tau them nyiaj ntau dua rau kev tiv thaiv cathodic disbondment kev ua tau zoo ntawm txheej txheej, yog li teeb tsa cov phiaj xwm luv luv thiab nruab nrab los tiv thaiv cathodic disbondment, suav nrog kev siv cov kav dej ntev. Qhov kub yog li teeb tsa qhov kub siab cathodic disbondment project. Los ntawm qhov ntsuas qhov ntsuas ntawm qhov pom, nws pom tseeb tias qhov kev tiv thaiv cathodic disbondment Performance index ntawm epoxy txheej yog siab dua, qhov siab tshaj plaws cathodic disbondment yog 8.5 hli ntawm chav tsev kub rau 28d, thiab qhov siab tshaj plaws cathodic disbondment ntawm qhov kub thiab txias yog 6.5 hli ntawm 48h. . Qhov ntsuas ntawm urea txheej yog qhov xoob, 12mm thiab 15m feem.
