Yog li dab tsi ua rau yellowing ntawm dawb marble? Yuav ua li cas cov dawb marble tuav nws thawj tsos? Cia peb muab rau koj ua kom yuam kev!
1. Cov qauv thiab muaj pes tsawg leeg ntawm pob zeb nws tus kheej
Kev tshawb fawb electron microscope ntawm cov dawb marble feem ntau pom tias cov hlau tsis muaj hlau nrog qhov ntau thiab tsawg ntawm 2 microns mus rau ntau pua microns muaj nyob rau saum npoo thiab kev ntxhib los mos ntawm dawb marble. Ib txhia muab faib rau saum npoo ntawm lub rooj tsavxwm, thiab ib txhia yog enriched nyob rau saum npoo ntawm cov dawb marble. Kab.
Cov oxidation ntawm hlau cov zaub mov muaj nyob rau hauv dawb marble yog ntseeg tias yog lub ntsiab ua rau yellowing ntawm marble. Vim tias feem ntau ntawm cov marbles muaj ib qho qauv zoo ib yam tshwj tsis yog rau cov nplej, thaum cov hlau uas muaj cov ntxhia hauv cov pob zeb sib xyaw ua ke tau oxidized los ua cov xim daj lossis xim av hydrated hlau oxides, cov teeb meem ntawm lub rooj tsavxwm tau tsim, thiab Kev xav zoo nkauj yog qhov tshwm sim no tshwj xeeb tshaj yog rau cov dawb marble.
Cov hlau hauv dawb marble feem ntau muaj nyob rau hauv daim ntawv ntawm ferrous sulfide, hlau carbonate thiab magnesium hlau silicate. Cov hlau ntxhia no tau tawg mus rau hauv marble matrix lossis enriched hauv marble kev ntxhib los mos.
Thaum cov hlau divalent hlau nyob rau saum npoo ntawm lub pob zeb yog oxidized los ntawm oxygen nyob rau hauv cov huab cua mus rau trivalent hlau thiab ua ke nrog dej los tsim hydrated hlau hydroxide, nws ua dab tsi peb feem ntau hu ua xeb, feem ntau hu ua yellowing. Yog tias tsis muaj kev tiv thaiv kev tiv thaiv, qhov zoo li no ntawm marble nto qaub ncaug yuav tshwm sim hauv 8-12 lub hlis tom qab lub pob zeb tso.
Ib qho tshwm sim nthuav yog tias qhov yellowing zoo li no tsis tshwm sim thaum muab tso rau ntawm qhov chaw sov, xws li marble ntawm ib sab ntawm cov kav dej kub. Qhov no qhia tau hais tias yellowing ntawm dawb marble yog ze ze rau kev ya raws. Txawm li cas los xij, kev sib cuag nrog dej tsis tas yuav ua rau yellowing ntawm dawb marble.
Kev kuaj thermal shock ntawm dawb marble pom tias cov qauv pob zeb tau tsau rau hauv dej deionized ntawm 15-25oC rau 6h, thiab tom qab ntawd cov qauv tau ci hauv qhov cub ntawm 100-110oC rau 18h. Tom qab 20 lub voj voog zoo li no, nws tau pom tias tsuas yog cov qauv hlau nplua nuj nyob rau saum npoo tau pom qhov tshwm sim daj me ntsis, thiab cov xim daj tau qis dua li qhov tshwm sim daj daj.
Qhov kev sim no qhia tau hais tias vim yog cov dej deionized tsawg heev, oxidation-txo cov tshuaj tiv thaiv ntawm divalent hlau mus rau trivalent hlau pib qeeb heev. Yog li ntawd, txawm hais tias tus qauv tau muab tso rau hauv dej rau lub sijhawm ntev thiab rov ua dua ntau zaus, tsis muaj qhov pom tseeb yellowing tshwm sim.
Qhov kev sim no qhia tau hais tias qhov tshwm sim daj daj ntawm cov pob zeb dawb yog qhov tshwm sim ntawm oxidation thiab hydration ua rau ntawm lub pob zeb nto divalent hlau minerals, thiab ob qho xwm txheej no yog qhov tseem ceeb. Tsis zoo li immersing nyob rau hauv dej ionized, dawb marble immersed nyob rau hauv alkaline tov yog heev yooj yim mus ua yellowing.
Muab tib lub pob zeb qauv tso rau hauv 15-25 ° C alkaline dej tsau rau 6 teev, thiab tom qab ntawd muab cov qauv tso rau hauv qhov cub ntawm 50-60 ° C rau ci rau 18 teev. Tom qab 20 lub voj voog zoo li no, qhov kev sim pom tias txhua qhov dawb marbles xaiv rau qhov kev sim tau daj, thiab Carrara dawb marble yog qhov hnyav tshaj plaws.
Alkaline tov yog ib qho yooj yim ua kom dawb marble daj. Yog vim li cas yog nyob rau hauv alkaline nruab nrab, oxidation-txo lub peev xwm ntawm ferric hlau yog oxidized rau ferric hlau, thiab nws yog yooj yim oxidized rau ferric hlau los ntawm oxygen nyob rau hauv cov huab cua. Kev sib xyaw ua ke ntawm cov dej ua rau muaj kuab paug daj rau ntawm lub rooj tsavxwm.
Cov hlau divalent ntawm lub pob zeb yog oxidized rau trivalent hlau los ntawm oxygen nyob rau hauv cov huab cua thiab ua ke nrog dej los tsim hydrated hlau hydroxide, uas muaj tsawg heev solubility. Yog li ntawd, yellowing pollution ntawm board nto tshwm sim los ntawm hlau yog tsis yooj yim rau muab tshem tawm. Hom thib ob ntawm yellowing kuab paug nyob rau saum npoo ntawm dawb marble slabs los ntawm cov organic teeb meem hauv marble. Cov organic teeb meem no muaj nyob rau hauv cov txheej txheem tsim ntawm marble thiab muaj cov qauv zoo ib yam li saprophytes.
Cov dej-soluble organic tshuaj tam sim no nyob rau sab hauv ntawm marble feem ntau tshwm xim daj-daj thaum reacting nrog dej alkaline. Vim muaj cov organic teeb meem no nyob rau hauv lub marble, thaum lub marble pem teb los yog phab ntsa tsis muaj dej kho nyob rau tom qab ntawm lub rooj tsavxwm yog ntsia rau hauv ntub pasting, alkaline dej ntawm cov cement slurry nkag mus rau hauv marble thiab reacts nrog cov organic. teeb meem hauv marble los tsim cov khoom xim Thaum cov khoom xim no tau coj mus rau saum npoo ntawm pob zeb los ntawm dej, qhov thib ob hom kev ua qias tuaj ntawm lub pob zeb yog tsim.
Txawm tias thaum lub sijhawm siv tom qab lub pob zeb tau teeb tsa, vim yog vim li cas huab cua, thaum twg dej nkag los ntawm cov cement pob zeb thiab tom qab ntawd ntws tawm ntawm pob zeb nto, nws yuav ib txwm coj tawm cov xim muaj kuab paug rau hauv pob zeb.
2. Sab nraud yog vim li cas
Qhov saum toj no ob hom kev ua qias tuaj ntawm dawb marble los ntawm cov khoom siv sab hauv thiab cov qauv ntawm cov pob zeb thiab tshwm sim nyob rau hauv kev cuam tshuam ntawm sab nraud. Ntxiv nrog rau ob hom kev ua qias tuaj cuam tshuam nrog cov khoom siv pob zeb thiab cov qauv, cov pa phem sab nraud kuj muaj cov hauv qab no:
1. Yellowing tshwm sim los ntawm hnav
Raws li polished nto ntawm marble hnav tam sim ntawd, av yog coj mus rau hauv qhov hws ntawm marble nto nrog taug kev, thiab cov av no ua rau saum npoo ntawm cov dawb marble tshwm daj.
2. Yellowing tshwm sim los ntawm kev saib xyuas tsis raug
Qhov kev saib xyuas tsis raug feem ntau yog mop hauv pem teb ntub nrog mop qias neeg. Cov av uas coj los ntawm cov qias neeg qias neeg hauv cov marble, ua rau saum npoo ntawm marble paug thiab daj.
3. Yellowing tshwm sim los ntawm waxing
Thaum siv quav ciab feem ntau yog siv los txhuam cov marble saum npoo, cov ntaub tuab tuab hloov daj vim nws txoj kev laus.
4. Yellowing tshwm sim los ntawm kev kho lub ntsej muag siv lead ua
Cov ntaub plaub hlau siv rau kev kho mob siv lead ua, nrog cov hmoov me me uas tseem tshuav nyob rau hauv micropores ntawm polished marble slab, dhau los ua lub hauv paus ntawm yellowing, tshwj xeeb tshaj yog thaum marble yog siv lead ua nto kho nyob rau hauv ib tug ntub lub xeev, yellowing hloov yog nquag tshwm sim.
5. Yellowing tshwm sim los ntawm cov txheej txheem installation
Yellowing tshwm sim los ntawm kev teeb tsa yooj yim rau kev saib, tab sis nws yog dav.
Ua ntej lub pob zeb hauv pem teb lossis phab ntsa raug teeb tsa, txawm hais tias lub npe hu ua rau-sided waterproof kev kho mob yog nqa tawm ntawm lub pob zeb specification board: lub hauv qab nto yog waterproof thiab glued, thiab plaub sab thiab pem hauv ntej nto yog kho nrog ib tug nkag mus rau waterproofing. tus neeg sawv cev.
Yog hais tias xws li ib tug 6-sided waterproof kev kho mob yog ua tau zoo heev, qhov zoo ntawm cov khoom uas xaiv waterproof yog guaranteed, thiab theoretically yuav tsum tsis txhob muaj ntau yellowing ntawm dej. Tab sis qhov tseeb yog tias txawm tias 6-sided waterproofing ntawm lub pob zeb slab ua ntej kev teeb tsa tau suav tias yog qhov zoo heev, thiab cov xim daj ntawm cov slab nto tseem tshwm sim ib ntus tom qab kev teeb tsa.
6. Yellowing ntawm pob zeb cov ntaub ntawv ntsig txog kev teeb tsa
Nws yog feem ntau tshwm sim los ntawm ob yam. Ib qho yog vim qhov loj me me, kev txiav ntawm qhov chaw rhuav tshem cov kev kho dej tsis zoo ntawm ib sab; Lwm qhov teeb meem tshwm sim yog tias qhov chaw tsim kho yog qias neeg thiab cov cement slurry ntog rau ntawm lub rooj tsavxwm nto thaum lub sijhawm tsim kho. Txhawm rau tiv thaiv cov cement slurry ntog los ntawm ziab ntawm lub board nto, so cov cement slurry nrog cov phuam ntub dej. Nyob rau lub sijhawm no, nws yog qhov ua tau los so cov dej alkaline cement uas muaj zog rau hauv qee qhov tsaus nti ntawm lub rooj tsavxwm, vim tias txawm tias nws tau ua tiav ntawm lub rooj tsavxwm yog permeable waterproof kev kho mob, tab sis nws yog tsis yooj yim sua rau me me dej- repellent molecules los tsim cov yeeb yaj kiab tiv thaiv thoob plaws qhov tawg ntawm qhov tawg kom tiv thaiv thiab tiv thaiv qhov tawg.
Yog li ntawd, qhov kev pab them nqi ntawm cov tshuaj tiv thaiv dej ntawm cov kab nrib pleb yog tsawg heev. Thaum txhim kho, siv rab riam grey txhawm rau txhawm rau sab ntawm lub rooj tsav xwm tshwj xeeb nrog cov cement muab tshuaj txhuam rov qab, uas tseem yuav rhuav tshem cov kev kho dej tsis zoo uas tau ua tiav. Yog tias cov dej cement tau raug coj mus rau hauv cov kab nrib pleb ntawm lub rooj tsavxwm thaum so lub rooj tsavxwm, qhov yellowing ntawm lub rooj tsavxwm yog qhov teeb meem sai dua lossis tom qab ntau dua li qhov nws yuav daj.
3. kev tiv thaiv cov teeb meem zoo xws li yellowing ntawm dawb marble, cov ntsiab lus hauv qab no yuav tsum tau them sai sai rau hauv cov txheej txheem ntawm kev ua thiab kev teeb tsa, txhawm rau ua kom cov dawb marble zoo kawg nkaus nthuav tawm kev zoo nkauj ntawm kev kho kom zoo nkauj.
1. Vim muaj cov khoom siv sab hauv ntawm marble
Lub yellowing tshwm sim los ntawm cov qauv tshwm sim los ntawm sab nraud tej yam kev mob. Qhov xwm txheej sab nraud no yog cov pa oxygen hauv dej thiab cua. Yog li ntawd, tsuav yog dej tau zoo tiv thaiv kom tsis txhob dhau los ntawm sab hauv ntawm lub pob zeb, lub yellowing los ntawm cov muaj pes tsawg leeg thiab cov qauv ntawm lub pob zeb yuav zoo suppressed.
2. Qhov zoo txhais tau tias tiv thaiv cov dej los ntawm sab hauv ntawm lub pob zeb yog kom tsis txhob muaj dej tsis zoo rau sab nraum qab ntawm lub rooj tsavxwm ua ntej txhim kho lub pob zeb. Kev kho dej thaum ntxov ntawm pob zeb slab rov qab tau pleev xim nrog siloxane / silane permeable waterproofing tus neeg saib xyuas. Cov ntaub ntawv tseeb qhia tau hais tias siv hom dej tsis zoo no los pleev xim rau sab nraum qab ntawm lub rooj tsavxwm tsis tuaj yeem cuam tshuam qhov tshwm sim ntawm pob zeb qhov txhab nrog rau yellowing. Permeable waterproofing agents muaj qee yam kev txwv.
Txawm hais tias tus neeg saib xyuas dej tsis zoo npaum li cas, nws cov dej tsis zoo yuav maj mam poob vim muaj kev cuam tshuam ib puag ncig. Qhov no yog vim li cas tom qab thawj daim ntawv thov ntawm tus neeg saib xyuas waterproofing, nws yuav tsum tau repainted nyob rau lub sij hawm tsis tu ncua los kho qhov deterioration ntawm nws cov dej tsis zoo. Vim li no, cov tshuaj tiv thaiv dej tsis zoo tsuas yog tsim rau cov laug cam uas tuaj yeem rov ua dua txhua lub sijhawm, xws li pem hauv ntej hauv pem teb lossis phab ntsa sab nraud.
Thaum siv cov tshuaj tua dej nkag mus rau hauv qab ntawm lub rooj tsavxwm, cov dej tshuaj tiv thaiv kev ua haujlwm ntawm cov tshuaj tiv thaiv dej tsis tuaj yeem saib xyuas. Txawm hais tias muaj cov cim qhia tias kev ua haujlwm ntawm tus neeg saib xyuas dej tsis zoo, peb tsis tuaj yeem rov ua dua thiab kho nws. Peb tsuas tuaj yeem cia nws deteriorate thiab thaum kawg poob cov dej tsis zoo tag nrho. Qhov no yog qhov laj thawj tseem ceeb vim li cas ntau qhov haujlwm siv cov txheej txheem kev teeb tsa hauv pem teb no thiab tseem tsis tuaj yeem zam cov pob zeb tawg.
Lub pob zeb tsis muaj dej nplaum nrog cov cement ua cov khoom siv hauv paus thiab siab molecular polymer emulsion tuaj ua. Hom dej nplaum no yog hu ua ob-tiv thaiv cov nplaum nplaum.
Ib qho kev tivthaiv yog cov cement ua lub cev tseem ceeb, nrog rau lwm cov khoom siv inorganic thiab ib qho me me ntawm cov khoom siv polymer, thiab lwm yam yog cov organic polymer emulsion. Qhov no ob-tiv thaiv cov nplaum nplaum yuav tsum muab sib xyaw rau ntawm qhov chaw. Cov neeg ua haujlwm uas tsis muaj kev paub txog kev txawj ntse feem ntau tsis paub txog qhov tseem ceeb ntawm qhov kev faib ua feem ntawm ob qho tib si thiab tsis sib xyaw ua ke nruj raws li qhov kev faib ua feem. Yog li ntawd, qhov zoo tsis tuaj yeem lav tag nrho.
Tsis tas li ntawd, muaj ntau lub npe ntawm hom no cov nplaum nplaum, thiab qhov zoo tsis sib xws. Piv txwv li, yog tias hom polymer hauv emulsion tsis raug xaiv kom raug lossis cov ntsiab lus ntawm cov khoom qis dhau lawm, nws yuav zoo li tsis muaj dej tsis zoo. Cov nplaum nplaum ob lub ntsiab lus no tsis haum rau dawb marble nrog cov ntsiab lus hlau siab lossis marble nrog cov kab nrib pleb tsaus nti, vim tias thaum siv cov nplaum nplaum no, cov dej muaj zog alkaline cement yuav nkag rau hauv cov pob zeb tam sim ntawd. Los yog capillary pores thiab nkag los ntawm lub rooj tsavxwm nto, yellowing ntawm lub rooj tsavxwm nto yuav tshwm sim sai.
3. Lub yellowing ntawm dawb marble tshwm sim los ntawm cov laj thawj sab nraud tuaj yeem tiv thaiv los ntawm kev siv thiab kev saib xyuas, xws li muab cov ntaub pua plag fiber ntau rau ntawm qhov nkag kom tshem tawm cov xuab zeb los yog lwm yam nyuaj ua ntej nkag mus rau hauv marble paving cheeb tsam kom txo cov tawv nqaij sab nraud. Kev puas tsuaj ntawm cov khoom ntawm cov pob zeb nto.
Lub mop uas siv los ntxuav hauv pem teb yuav tsum huv si, thiab cov dej uas siv los ntxuav hauv pem teb yuav tsum huv. Tom qab mopping hauv pem teb, so cov dej hauv av kom huv si, thiab siv cov mopping qhuav kom tsawg li sai tau. Yog tias ua tau, nws yog qhov zoo tshaj plaws los siv cov dej ntxuav marble rau kev tu. Pem teb waxing tau ua pov thawj tias yog ib txoj hauv kev tswj hwm marble slabs uas ua rau muaj kev phom sij ntau dua li qhov zoo.
Ua ntej tshaj plaws, lub gloss ntawm av polished nrog wax tsis kav ntev. Ntawm qhov tod tes, feem ntau ntawm cov quav ciab thaiv cov qhov cua ntawm lub pob zeb, uas cuam tshuam cov pa roj ntawm cov marble uas hloov nrog huab cua.
Thaum kawg, thaum cov khoom siv quav ciab ntau dhau los ua daj vim kev laus thiab yuav tsum tau muab tshem tawm, yuav tsum siv cov quav quav quav quav. Kev siv cov wax tshem tawm yuav cuam tshuam rau huab cua sab hauv tsev. Crystal deg kho yog ib qho kev kho polishing feem ntau siv rau hauv pem teb marble. Xaiv qhov tseeb siv lead ua tus neeg sawv cev tuaj yeem ua rau saum npoo ntawm cov pob zeb kho kom tau txais cov yeeb yaj kiab tuab, ci ntsa iab uas tsis cuam tshuam rau cov pob zeb permeability.
Txawm li cas los xij, thaum ua cov khoom siv lead ua, xws li polishing nrog steel wool, cov hmoov hlau tawg tawg yuav tsum tau nqus. Ib qho hlau wool nplua hmoov nyob rau hauv av yuav dhau los ua ib qho kev ua qias tuaj rau yellowing ntawm lub rooj tsavxwm.
4. Cov kws tshaj lij ntawm kev teeb tsa pob zeb yuav tsum muaj lub hauv paus kev tshaj lij, nkag siab txog cov laj thawj ntawm pob zeb daj, muaj cov kev txawj tsim nyog rau kev txhim kho pob zeb, ua kom lub tsev tsim kho kom huv si thiab huv si, thiab tsis txhob yellowing ntawm pob zeb los ntawm kev teeb tsa.
Kev saib xyuas rau pob zeb, tsis txhob qhia cov hlau uas yuav ua rau lub pob zeb daj los ntawm kev ntxuav dej los yog hauv pem teb polishing txheej txheem. Siv cov khoom zoo zoo nkag mus rau cov dej tsis zoo los tiv thaiv hauv pem teb tsis tu ncua kom txo tau lub sijhawm thiab lub sijhawm ntawm dej thiab pob zeb sib cuag.
Yog li ntawd, kev tiv thaiv zoo ntawm yellowing ntawm dawb marble yuav tsum yog ib qho kev ntsuas. Nyob rau hauv cov ntaub ntawv uas cov cement pem teb los yog phab ntsa tsis zoo waterproofed, kev kho mob ntawm lub nraub qaum ntawm lub pob zeb slab yog ib qho tseem ceeb tshwj xeeb. Xaiv qhov zoo-gua kom tsis muaj dej nplaum nplaum rau cov dej tsis qab ntawm lub rooj tsavxwm yog qhov tseem ceeb tshaj plaws hauv txhua qhov kev ntsuas.
4.Qhov kev tshem tawm ntawm yellowing ntawm pob zeb nto
Thaum lub yellowing ntawm cov dawb marble saum npoo yog pom, ua ntej nrhiav qhov laj thawj rau yellowing. Ua ntej tig qhov xav tias ua rau yellowing yuav cuam tshuam nrog xeb, ua ntej kom paub tseeb tias qhov yellowing tsis yog tshwm sim los ntawm kev laus wax los yog lwm yam sab nraud. Tom qab tsis suav nrog lwm yam tsis yog hlau, pib npaj rau kev tshem tawm xeb.
Tam sim no, muaj ntau hom hlau thiab yellowing agents nyob rau hauv cov khw muag pob zeb. Txawm hais tias tsis muaj cov khoom lag luam nthuav tawm cov tshuaj lom neeg muaj pes tsawg leeg, feem ntau ntawm cov hlau thiab yellowing agents ntawm lub khw yog acidic. Vim tsis zoo acid tsis kam ntawm marble, ntau acidic xeb tshem tawm muaj corrosion zoo heev ntawm lub rooj tsavxwm thaum tshem tawm xeb. Kev yaig ntau dhau ntawm marble nto yuav ua rau muaj kev puas tsuaj mus tas li.
Yog li ntawd, thaum siv cov xeb tshem tawm, nco ntsoov lo ob peb txheej ntawm daim ntawv tso quav tso rau ntawm qhov chaw ntawm lub pob zeb thaum tshem cov xim daj, thiab tom qab ntawd muab cov tshuaj txhuam hniav tso rau ntawm daim ntawv. Tos li ob teev, daj yuav maj mam txo, thiab tom qab ob peb zaug, cov daj tuaj yeem raug tshem tawm. Cov neeg ua haujlwm saib xyuas pob zeb feem ntau siv cov tshuaj tsis muaj zog acidic lossis txawm tias cov neeg ua haujlwm huv huv kom txo qis kev puas tsuaj rau pob zeb.
Rau cov tawv nqaij xeb, ib txoj kev muab tshuaj txhuam yog saws, uas yog, cov xeb tshem tawm yog tov nrog diatomaceous lub ntiaj teb rau hauv ib qho muab tshuaj txhuam nrog dej, thiab tom qab ntawd muab tshuaj txhuam yog siv rau cov kab xeb, npog nrog yas zaj duab xis thiab kaw nrog daim nplaum nplaum.
