Nrog rau txoj kev loj hlob ntawm kev tsim kho kev lag luam thiab kev nce qib ntawm kev tsim kho technology, nyob rau hauv lub tshav pob ntawm granite, ntau yam ntaub ntawv tshiab thiab cov thev naus laus zis tshiab tau siv rau ntau yam kev kho kom zoo nkauj sab nrauv. Ntuj granite nws tus kheej muaj cov yam ntxwv ntawm kev ntxhib los mos zoo, zoo nkauj, zoo heev lub cev, thiab lwm yam, thiab tau them nyiaj mloog mus rau thiab nqa mus tom ntej los ntawm tib neeg. Txawm li cas los xij, hauv qee qhov haujlwm, tom qab lub sijhawm ua tiav, qee qhov haujlwm yuav muaj teeb meem zoo xws li "efflorescence" ntawm pob zeb, uas yog ib qho teeb meem loj. Muaj feem cuam tshuam qhov kawg ntawm tag nrho cov kev kho dua tshiab. Yog li, pob zeb "efflorescence" yog dab tsi thiab nws tshwm sim li cas?
Yuav ua li cas "efflorescence" nyob rau hauv lub pob zeb tu tuaj txog?
Lub npe hu ua pob zeb grout feem ntau yog vim qhov zoo ntawm kev teeb tsa ntawm cov khoom siv hauv tsev, ua rau cov dej noo ntau dhau hauv lub tsev. Tom qab lub sijhawm ntev, qhov saum npoo yuav tshwm sim dawb ntws cov cim, cov pob dawb, cov dej me me, cov cim ntub dej thiab lwm yam xim tsis sib xws. Cov lus hais txog kev rov qab los ntawm pob zeb efflorescence tsis tshua siv, thiab tam sim no ntau cov neeg pob zeb nyiam siv cov lauj kaub-alkali thiab rov qab-alkali los piav txog qhov tshwm sim no.
Qhov tshwm sim ntawm qhov xwm txheej no feem ntau cuam tshuam nrog cov calcium carbonate exudation los ntawm cov cement siv rau kev sib cuag mus ntev.
Yog vim li cas rau "efflorescence" nyob rau hauv lub pob zeb tu
1. Nws yog feem ntau siv cov cement mortar dai ntub txoj kev thaum lub sij hawm installation ntawm lub tsev cov ntaub ntawv. Thaum lub sij hawm lub installation txheej txheem ntawm lub tsev cov ntaub ntawv, tom qab installation, cov dej sab nraud yuav infiltrate lub gypsum thiab alkali ntsev Cheebtsam nyob rau hauv cov cement, ua rau cov ntaub ntawv thiab ntau yam kua ntawm internal impurities maj nkag mus rau hauv lub pob zeb thiab hangs nyob rau saum npoo ntawm lub pob zeb. thiaj li hu ua efflorescence;
2. Nyob rau hauv cov txheej txheem installation ntawm qee lub tsev, tshwj xeeb tshaj yog nyob rau sab nrauv phab ntsa, cov neeg ua haujlwm nyias nyias nyob rau hauv cov txheej txheem ntawm kev sib xyaw thiab npaj cov cement thiab pob zeb, thiab cov dej ntau volatilizes maj mam tom qab kev teeb tsa, ua rau muaj qhov tshwm sim ntawm hollowing sab hauv. , cia dej nkag los ntawm sab nraud. Sab hauv tsis tu ncua reacts nrog cement los tsim efflorescence;
3. Qee cov neeg ua haujlwm tsis tau xyuam xim rau kev siv cov khoom siv hauv tsev thaum txhim kho cov khoom siv hauv tsev, uas tseem yuav ua rau hollowing sab hauv, ua rau cov pob zeb efflorescence tsim;
4. Qee tus neeg ua haujlwm tsis quav ntsej txog kev kho dej tsis zoo ntawm cov pob qij txha thaum ua haujlwm. Tom qab nkag los ntawm nag thiab dej vapor (tshwj xeeb tshaj yog cov kua qaub nag), nws yog ib qho yooj yim los nqa tawm cov gypsum sab hauv thiab ua rau phab ntsa rov qab mus rau lub grout. Qhov xwm txheej no muaj qee qhov xwm txheej. Nws muaj ntau heev nyob rau yav qab teb cheeb tsam;
5. Txawm hais tias qee tus neeg ua haujlwm tau pom qhov kev kho dej tsis zoo ntawm cov pob qij txha, vim yog kev xaiv ntawm qee cov kua qaub silicone sealants, structural adhesives, marble glues, thiab maj mam corrosion ntawm cov khoom siv hauv tsev thiab cement tom qab kev teeb tsa, cov nyhuv ntawm cov dej tom qab ntawd maj mam. tsim efflorescence ntawm pob zeb nto. Hauv ntau qhov chaw sab nraum zoov, muaj qhov tshwm sim siab ntawm pob zeb rov qab grout ntawm tus ntaiv.
Ntxiv nrog rau cov xwm txheej saum toj no, cov khoom siv hauv tsev thiab cov veneers tsis raug ntxuav thaum ua haujlwm, uas yuav ua rau qee cov pa phem (greas, plua plav, grit, thiab lwm yam) rau cov khoom siv hauv tsev thiab veneers lawv tus kheej. Tom qab lub veneer yog veneered, nws yog ib qho yooj yim ua rau lub tsev cov ntaub ntawv thiab cov cement mortar kom tsis txhob kaw nruj nreem, ua rau lub phenomenon ntawm hollowing. Thaum cov dej nkag mus tob, nws yuav ua rau cov calcium carbonate tawm thiab tsim cov pob zeb efflorescence.
