Cov ntaub ntawv siv:
Epoxy cob: Kev txhaj tshuaj epoxy yog ib txoj hauv kev uas muaj kev txhaj tshuaj epoxy resin rau hauv cov kab nrib pleb. Epoxy yog cov khoom siv nplaum uas muaj zog heev uas tuaj yeem sib txuas nrog cov pob zeb, zoo sealing qhov tawg thiab muab cov txheej txheem ntxiv.
Polyurethane Resin: Polyurethane txhaj tshuaj yog lwm txoj kev siv los kho cov kab nrib pleb. Polyurethane nthuav dav thaum txhaj tshuaj, sau cov voids thiab cov kab nrib pleb thaum tseem muab lub foob hloov tau. Nws yog tshwj xeeb tshaj yog pab tau rau cov ntawv thov waterproofing.
Txheej txheem:
Cov txheej txheem txhaj tshuaj feem ntau muaj cov kauj ruam hauv qab no:
Kev npaj nto: Cov pob zeb uas puas lawm yog ntxuav thiab npaj kom zoo adhesion ntawm cov khoom txhaj tshuaj. Qhov no yuav suav nrog tshem cov khib nyiab, plua plav, lossis cov khoom paug.
Drilling qhov: Cov qhov me me yog drilled raws qhov ntev ntawm qhov tawg los yog ntawm cov ntu tshwj xeeb, nyob ntawm txoj kev kho. Cov qhov no ua cov ntsiab lus nkag rau cov khoom siv txhaj tshuaj.
Txhaj tshuaj: Cov khoom siv txhaj tshuaj uas tau xaiv (epoxy lossis polyurethane) yog txhaj rau hauv qhov npaj siv cov khoom siv tshwj xeeb. Cov txheej txheem txhaj tshuaj yog ua tib zoo saib xyuas kom ntseeg tau tias cov khoom ntws los ntawm tag nrho qhov ntev ntawm qhov tawg lossis tsis muaj dab tsi.
Expansion thiab sealing: Yog tias siv polyurethane, nws nthuav dav thaum txhaj tshuaj kom sau cov kab nrib pleb lossis void kiag li. Epoxy resin bonds nrog cov pob zeb thiab ua kom muaj zog, tsis muaj dej tsis zoo.
Kho: Cov khoom siv txhaj tshuaj raug tso cai kho thiab tawv. Lub sijhawm kho nws txawv nyob ntawm seb cov khoom siv thiab ib puag ncig.
Daim ntawv thov:
Kev txhaj tshuaj yog ua haujlwm rau ntau lub hom phiaj, suav nrog:
Kev kho vaj tse: Nws yog siv los kho cov kab nrib pleb thiab qhov tsis xws ntawm cov pob zeb ua vaj tse xws li cov tsev, txuas hniav, thiab cov dams. Qhov no yuav pab kho cov txheej txheem kev ncaj ncees ntawm cov pob zeb.
Waterproofing: Kev txhaj tshuaj tuaj yeem siv los kaw cov kab nrib pleb thiab tiv thaiv cov dej nkag hauv qab daus, qhov av, thiab lwm cov qauv hauv qab.
Kev kho vaj tse: Nws yog siv rau kev kho dua tshiab ntawm cov vaj tsev ua vaj tse historic, khaws cia lawv cov vaj tse thiab kev ncaj ncees.
Pob Tawb Strengthening: Kev txhaj tshuaj tuaj yeem ntxiv dag zog rau pob zeb los ntawm kev sau cov voids thiab cov kab nrib pleb, txhim kho nws lub peev xwm thauj khoom.
Qhob Preservation: Kev saib xyuas tsis tu ncua thiab kev txhaj tshuaj tuaj yeem txuas ntxiv lub neej kev pab cuam ntawm cov vaj tse pob zeb, txo qhov kev xav tau ntawm kev kho tus nqi lossis kev hloov pauv.
Kev txhaj tshuaj pob zeb yog ib txoj hauv kev zoo thiab siv tau zoo rau kev kho thiab khaws cov vaj tse pob zeb, thiab nws feem ntau siv ua ke nrog lwm cov kev kho vaj tse. Kev ua tiav cov pob zeb ua kom zoo tuaj yeem txuas ntxiv lub neej ntawm cov pob zeb ua vaj tse thiab txhim kho lawv cov kev ua tau zoo thiab kev nyab xeeb.
