Tab sis tib lub sijhawm nws tseem nyiam tshaj plaws thiab ntshai ntau yam, tab sis kev ua siab phem, puas yooj yim, thiab nyuaj rau tos dawb marble hauv anti-fouling tau ua rau qee cov neeg siv kev zam txim rau nws, tshwj xeeb yog qhov tseeb tias dawb marble yooj yim daj. Cov neeg siv dawb marble nyob deb.
Yog tias peb xav kom daws tau cov teeb meem zoo xws li cov plaub hau dawb plaub hau daj, ces peb yuav tsum txheeb xyuas qhov teeb meem sab hauv thiab sab nraud, nkag siab zoo kom paub meej ntawm cov khoom ntawm marble, thiab lub hauv paus ntawm cov teeb meem zoo, ces peb tuaj yeem daws cov teeb meem tseem ceeb. Yog li dab tsi ua rau yellowing ntawm dawb marble? Yuav ua li cas dawb marble tuav nws cov thawj cov tsos? Nov' s yuav ua li cas!
1. Cov qauv thiab cov khoom siv ntawm lub pob zeb nws tus kheej
Kev soj ntsuam hluav taws xob hauv tshuab hluav taws xob tsom rau qhov feem ntau dawb dawb marble pom pom tias cov hlau muaj hlau nrog cov qhov ntau thiab tsawg ntawm 2 microns mus txog ntau pua microns muaj nyob rau saum npoo thiab kev ntxhib los mos ntawm dawb marble. Qee qhov muab faib rau ntawm cov npoo, thiab qee qhov ntxiv tawm hauv kab.
Qhov oxidation ntawm cov hlau tsis muaj nyob hauv dawb marble yog ntseeg tau hais tias yog lub hauv paus tseem ceeb ntawm yellowing ntawm lub marble. Vim tias feem ntau ntawm cov moj bis muaj ib qho qauv thiab qhov tsis sib xws tshwj tsis yog cov nplej, thaum cov hlau uas muaj cov khoom noj khoom tawg yooj yim tawg rau hauv cov pob zeb yog oxidized tsim cov xim daj los yog xim av hydrated hlau oxides, tsis xws luag ntawm lub rooj tsavxwm yog tsim, thiab kev zoo nkauj yog Qhov tshwm sim no tshwj xeeb tshaj yog rau cov dawb marble.
Cov hlau nyob hauv dawb marble feem ntau muaj nyob rau hauv daim ntawv ntawm ferrous sulfide, hlau carbonate thiab magnesium hlau silicate. Cov khawb hlau tsis zoo no tau ua rau hauv marble matrix lossis nplua nuj hauv qhov kev ntxhib los mos marble.
Thaum cov hlau sib txawv hauv cov pob zeb saum npoo zeb tau oxidized los ntawm oxygen nyob rau hauv huab cua kom trivalent hlau thiab txuas nrog dej los ua hydrated hlau hydroxide, nws ua cov dab tsi peb feem ntau hu xeb, feem ntau hu ua daj. Yog tias tsis muaj kev tiv thaiv kev ntsuas, qhov hom ntawm kev txhawm rau marble yuav tshwm sim hauv 8-12 lub hlis tom qab tau muab tso rau ntawm marble.
Qhov tshwm sim nthuav dav yog tias qhov kev hais xim daj no tsis tshwm sim thaum muab tso rau ntawm cov khoom siv cua sov, xws li marble ntawm ib sab dej kub. Qhov no qhia tau hais tias daj daj ntawm dawb marble yog ze ze rau ya raws. Txawm li cas los xij, kev sib cuag nrog cov dej tsis tas yuav ua rau yoov txhav dawb.
Qhov ntsuas kub ntawm lub teeb dawb ntawm marble pom pom tias cov qauv pob zeb tau tsau hauv cov dej deionized ntawm 15-25oC rau 6h, thiab tom qab ntawd cov hnoos qeev tau muab ci hauv qhov cub ntawm 100-110oC rau 18h. Tom qab 20 lub voj voog tas li, nws tau pom tias tsuas yog cov qauv ntawm cov hlau uas muaj saum npoo av tau pom tias maj mam daj me ntsis, thiab lub ntsej muag daj tau qis dua lub ntuj daj dua.
Qhov kev sim no tau qhia tias, vim muaj qhov qis heev ntawm kev deionized dej, qhov oxidation-txo cov tshuaj tiv thaiv ntawm divalent hlau rau trivalent hlau proceeds qeeb heev. Yog li no, txawm hais tias qhov qauv tau muab raus hauv dej ntev thiab rov ua ntau zaus, tsis muaj qhov pom tseeb tias daj daj pom tshwm.
Qhov kev ntsuas no qhia tau hais tias qhov yellowing phenomenon ntawm dawb marble yog txiaj ntsig ntawm oxidation thiab hydration ua rau ntawm lub pob zeb. Ob qho ntawm cov mob no yog qhov tseem ceeb. Tsis zoo li raus hauv dej ionized, dawb marble immersed hauv alkaline kev daws yog yooj yim heev los ua kom daj.
Tso cov pob zeb tib qho hauv 15-25 ° C alkaline dej tsau dej rau 6 teev, thiab tom qab ntawd muab cov hnoos qeev coj los tso hauv qhov cub ntawm 50-60 ° C rau 18 teev. Tom qab 20 qhov kev voj voog, qhov kev kuaj pom pom tias txhua tus moj bis dawb xaiv rau qhov kev sim tau daj, thiab Carrara dawb marble yog qhov loj tshaj.
Cov tshuaj Alkaline yog ib qho yooj yim kom dawb marble daj. Qhov laj thawj yog tias nyob hauv nruab nrab alkaline, lub redox muaj peev xwm ntawm ferric hlau yog oxidized rau ferric iron, thiab nws yog yooj yim oxidized rau ferric hlau los ntawm oxygen hauv huab cua. Dej sib xyaw ua ke ua cov xim av daj rau saum npoo ntawm pawg thawj coj.
Qhov zawv hlau ntawm pob zeb saum npoo yog oxidized rau trivalent hlau los ntawm oxygen nyob rau hauv huab cua thiab ua ke nrog dej los tsim hydrated ferric hydroxide, uas muaj solubility tsis tshua muaj siab. Yog li ntawd, lub teeb meem daj ntawm lub rooj tsavxwm los ntawm cov hlau tsis tuaj yeem tshem tawm yooj yim. Qhov thib ob hom yellowing kev ua qias tuaj ntawm dawb marble slab nto los ntawm cov organic teeb meem hauv marble. Cov organic teeb meem no muaj nyob rau hauv cov txheej txheem tsim ntawm marble, thiab nws cov qauv zoo ib yam li cov nroj tsuag rot.
Cov dej-soluble organic tshuaj tshwm sim nyob rau sab hauv ntawm marble feem ntau tshwm sim xim daj-daj daj thaum cuam tshuam nrog dej alkaline. Vim hais tias muaj cov teeb meem ntawm cov organic no sab hauv marble, thaum marble pob zeb los yog phab ntsa tsis muaj kev kho dej tsis qab nyob rau sab nraum qab ntawm lub rooj tsavxwm tau nruab rau hauv cov dej ntub, cov dej alkaline ntawm lub grout nkag mus rau ntawm marble thiab reacts nrog cov organic teeb meem hauv cov khoom lag luam ua xim zeb ua rau cov khoom lag luam xim Thaum cov khoom siv xim no coj mus rau saum npoo ntawm pob zeb los ntawm dej, hom ob ntawm cov pa phem rau saum npoo ntawm lub pob zeb yog tsim.
Txawm nyob rau lub sijhawm siv tom qab lub pob zeb tau txhim kho, vim yog huab cua, thaum twg dej txia tawm ntawm cov pob zeb saum npoo tom qab dhau ntawm cov pob zeb ua vaj tse, nws yuav ib txwm coj tawm cov xim muaj kuab paug rau cov pob zeb.
2. Sab nraud vim li cas
Qhov saum toj no ob hom kev ua qias tuaj ntawm dawb marble yog los ntawm kev sib xyaw ua ke sab hauv thiab cov qauv ntawm pob zeb, uas tshwm sim nyob rau hauv kev cuam tshuam ntawm cov xwm txheej sab nraud. Ntxiv rau ob hom kev ua qias tuaj ntsig txog cov pob zeb thiab cov qauv, kev ua qias tuaj sab nraud muaj cov hauv qab no:
1. Cov daj daj ua rau hnav
Raws li qhov chaw polished ntawm pob zeb hnav, av yog coj mus rau hauv lub qhov hws ntawm marble saum npoo nrog taug kev, thiab cov av no ua rau dawb marble saum npoo daj.

Lub pob zeb siv hlau siv rau kev kho mob saum npoo, nrog cov hmoov me me zoo uas tseem tshuav nyob hauv cov micropores ntawm polished marble slab, dhau los ua qhov chaw daj, tshwj xeeb tshaj yog thaum marble tseem siv lead ua saum npoo kho nyob rau hauv lub xeev ntub, yellowing kev hloov yog nquag tshwm sim.
5. Kev daj ua tshwm sim los ntawm cov txheej txheem teeb tsa
Kev daj daj tshwm sim los ntawm kev teeb tsa yog yooj yim rau kev saib xyuas, tab sis nws yog thoob plaws.
Ua ntej pob zeb hauv pem teb lossis phab ntsa tau teeb tsa, txawm hais tias qhov thiaj li hu ua kev sib tua ua rau 6 qhov dej yog ua rau ntawm lub pob zeb qhia kom meej: qhov chaw hauv qab yog dej thiab nplaum, plaub sab thiab sab pem hauv ntej yog kho nrog tus neeg sawv cev dej nkag.
Yog tias qhov kev tso dej zoo li 6-qhov no ua tau zoo heev, qhov zoo ntawm cov khoom siv dej uas raug xaiv kuj tseem lav tau, thiab raws li kev xav yuav tsum tsis muaj qhov dej daj ntsig txog daj. Tab sis qhov tseeb yog tias txawm li ntawm 6-ib tog kev thim dej ntawm lub pob zeb txiag ua ntej kev teeb tsa yog suav tias yog qhov ua tau zoo heev, thiab lub suab daj ntawm lub rooj tsavxwm sab nraud tseem tshwm sim txij ua ke mus ua ke tom qab kev teeb tsa.
6. Cov ntawv daj ua pob zeb cuam tshuam txog kev teeb tsa
Nws yog tsuas yog tshwm sim los ntawm ob yam. Ib qho yog vim tias qhov teeb tsa loj me me, kev txiav tawm ntawm lub tsev kawm raug rhuav tshem cov kev kho dej tsis huv ntawm qee yam; lwm qhov xwm txheej tau yog qhov chaw tsim kho yog qias neeg thiab cov cement slurry poob rau ntawm lub rooj tsavxwm saum npoo av thaum lub sijhawm kev tsim kho. Txhawm rau tiv thaiv kom tsis txhob poob cov cement slurry los ntawm kom qhuav ntawm lub rooj tsavxwm saum npoo, so cov ntaub pua plag slurry nrog cov phuam ntub. Nyob rau lub sijhawm no, nws muaj peev xwm ntau los so lub zog lim dej alkaline cement rau qee qhov tawg me me ntawm daim txiag. Tso cai siv dej tshuaj pleev xim rau ntawm qhov chaw tswjhwm, tab sis cov tshuaj me me tshuaj pleev cov dej tsis tuaj yeem tsim ib zaj duab xis tiv thaiv thoob plaws ntawm pob zeb tawg kom tawg thiab tiv thaiv qhov tawg.
Yog li ntawd, cov kev tiv thaiv cov dej los ntawm cov dej sawv cev ntawm cov kab nrib pleb no tsawg heev. Thaum txhim kho, siv lub ntsej muag txho los txhuam sab ntawm lub vaj huam sib luag los ua pawg nrog cov xis mas muab rov qab thiab dua, uas tseem yuav rhuav tshem cov kev kho dej tsis ua haujlwm uas tau ua tiav. Yog tias cov dej hauv cov pob zeb tsis ncaj ncees nqa mus rau hauv qhov tawg ntawm pawg thaum so lub rooj tsav xwm, lub suab daj ntawm lub rooj tsavxwm yog qhov teeb meem ntawm lub sijhawm, tsis hais nws yuav tig daj.
3.Txog kev tiv thaiv yellowing ntawm dawb marble thiab lwm yam teeb meem zoo, cov ntsiab lus hauv qab no yuav tsum tau them sai sai rau hauv kev tsim thiab txheej txheem, kom cov dawb marble tuaj yeem nthuav qhia qhov zoo nkauj ntawm kho kom zoo nkauj.
1. Vim muaj sab hauv muaj pes tsawg leeg ntawm marble
Qhov kev daj ua rau cov qauv tshwm sim los ntawm cov xwm txheej sab nraud. Qhov xwm txheej sab nraud yog cov pa oxygen hauv dej thiab cua. Yog li no, ntev npaum li qhov dej tau tiv thaiv kom tsis txhob dhau los ntawm lub pob zeb, yellowing tshwm sim los ntawm cov lus muaj pes tsawg leeg thiab cov qauv ntawm lub pob zeb yuav raug tswj hwm zoo.
2. Txoj hauv kev tiv thaiv txoj hauv kev los tiv thaiv dej los ntawm lub pob zeb yog dej thaiv dej ua ke sab nraum qab ntawm lub rooj tsavxwm ua ntej txhim kho lub pob zeb. Kev kho thaum ntxov dej ntawm pob zeb slab thaub qab tau pleev xim nrog siloxane / silane permeable waterproofing tus neeg sawv cev.
