Feem ntau yog pob zebCov ntaub npog nyob rau hauv daim ntawv ntawm ib qho grouted nto los yog ib tus neeg cov vuas rau nteg tawm sab nraum zoov tsis raug kho nrog cov tshuaj tiv thaiv, uas ua rau lawv hnav sai thiab cov tsos ntawm cov plua plav saum npoo.
Ib qho kev tiv thaiv tshwj xeeb tiv thaiv cov txheej txheem saum toj kawg nkaus ntawm cov khoom los ntawm kev puas tsuaj ntawm cov dej thiab khaws cov tsos. Tsis tas li ntawd, muaj kev tiv thaiv corrosion ntawm steel reinforcement nyob rau hauv pob zeb ua qauv. Chlorides los yog sodium cov ntsiab lus ntxiv rau cov khoom muaj pes tsawg leeg ua rau muaj kev nkag mus ntawm cov dej noo mus rau hauv qhov pores, tuaj yeem ua rau xeb thiab ua rau lub neej ua haujlwm luv. Nrog xws li additives, ib tug tshwj xeeb impregnation rau pob zeb yog ib tug yuav tsum.
Cov tshuaj muaj pes tsawg leeg uas tiv thaiv cov ntaub ntawv los ntawm kev nkag mus ntawm noo noo feem ntau hu ua hydrofabricators hauv kev tsim kho. Lawv tsis tsuas yog tiv thaiv cov qauv ntawm kev tawg thiab kev puas tsuaj, tab sis kuj tiv thaiv cov tsos ntawm efflorescence, uas yog, ntsev stains. Nws yog efflorescence uas tuaj yeem ua rau kev puas tsuaj ntawm txheej txheej ntawm cov pob zeb ua kom tiav. Tej impregnation rau pob zeb los ntawm ya raws yuav tiv thaiv lawv tsim.
Protexil
Rau kev tshem tawm thiab tsim cov txheej txheem tshwj xeeb, Protexil impregnation rau pob zeb kuj zoo heev thiab ntau yam.
