Kev tsim cov hmoov putty zoo yuav tsum nkag siab txog nws cov yam ntxwv thiab xyuas kom meej tias nws ua tau raws li qee qhov kev ua tau zoo thiab cov qauv siv. Putty, tseem hu ua phab ntsa putty lossis phab ntsa filler, yog cov hmoov cement dawb zoo siv los sau cov qhov tsis zoo ntawm cov phab ntsa plastered, cov pob zeb ua vaj tse thiab masonry ua ntej pleev xim lossis wallpapering. Nws lub luag haujlwm tseem ceeb yog kom du cov nplaim, sau cov kab nrib pleb thiab muab lub hauv paus sib npaug rau kev pleev xim lossis ua tiav.
1. Cov khoom xyaw ntawm cov hmoov putty:
Cov Khoom Siv Sib Txuas: Cov khoom sib txuas hauv cov hmoov putty feem ntau muaj cov cement dawb, gypsum lossis sib tov ua ke. Cov ntaub ntawv no ua rau cov hmoov lo thiab sib txuas ua ke, ua rau nws lo rau ntawm qhov chaw thiab tsim kom muaj kev sib txuas zoo.
Cov Tshuaj Sau: Cov tshuaj sau xws li calcium carbonate lossis talc feem ntau raug ntxiv rau kom txhim kho qhov zoo nkauj thiab qhov ntim ntawm cov putty. Cov tshuaj sau no pab txhawb rau qhov du thiab ua haujlwm tau zoo ntawm cov khoom.
Cov Khoom Hloov Kho/Cov Khoom Ntxiv: Muaj ntau yam khoom ntxiv uas koj ntxiv tau los txhim kho cov yam ntxwv ntawm cov hmoov putty. Piv txwv li, cov cellulose ethers los txhim kho kev khaws dej thiab kev ua haujlwm tau zoo, cov polymers los ua kom yooj ywm thiab lo rau, thiab cov tshuaj preservatives los tiv thaiv kev loj hlob ntawm cov kab mob me me.
2. Cov khoom uas yuav tsum tau muaj ntawm cov hmoov putty:
Kev Zoo: Cov hmoov putty yuav tsum muaj qhov loj me me kom ntseeg tau tias kev siv du thiab ua tiav qhov chaw sib xws. Qhov zoo kuj tseem pab kom lo rau thiab kho qhov tsis zoo.
Kev nplaum: Cov putty yuav tsum nplaum zoo rau ntau yam substrates xws li concrete, plaster thiab masonry. Kev nplaum zoo ua kom cov putty nplaum ruaj khov rau ntawm qhov chaw thiab yuav tsis tawg lossis tev tawm raws sijhawm.
Kev Ua Haujlwm Tau Zoo: Kev ua haujlwm tau zoo yog qhov tseem ceeb rau kev siv thiab ua kom yooj yim rau cov putt. Nws yuav tsum du thiab yooj yim rau kev siv yam tsis tas siv zog ntau dhau, ua kom puv cov kab nrib pleb thiab qhov zoo.
Kev Tiv Thaiv Kev Ntsws: Cov hmoov putty yuav tsum tsis txhob ntsws me me thaum nws qhuav kom tiv thaiv kev tawg lossis qhov sib txawv hauv cov txheej. Kev ntsws me me ua kom tiav tau ntev.
Kev Tiv Thaiv Dej: Txawm hais tias cov hmoov putty feem ntau yog siv rau kev siv sab hauv tsev, nws tseem yuav tsum muaj qee qib kev tiv thaiv dej kom tiv taus qee zaum raug dej noo thiab av noo yam tsis muaj kev puas tsuaj.
Lub sijhawm qhuav: Lub sijhawm ziab ntawm cov hmoov putty yuav tsum tsim nyog kom cov xim pleev xim lossis ua tiav tiav raws sijhawm. Cov mis qhuav sai yog qhov xav tau rau kev ua tiav qhov project sai dua.
Kev Xuab Zeb: Thaum qhuav lawm, cov putty yuav tsum yooj yim xuab kom muab qhov chaw du thiab tiaj rau kev pleev xim lossis phab ntsa. Kev xuab zeb pab txhawb rau qhov zoo thiab qhov tsos ntawm tag nrho.
Kev Tiv Thaiv Kev Tawg: Cov hmoov putty zoo yuav tsum tiv taus kev tawg, txawm tias nyob rau hauv ib puag ncig uas qhov kub hloov pauv lossis kev txav mus los ntawm cov qauv yuav tshwm sim.
Kev Sib Xws Nrog Xim: Hmoov Putty yuav tsum sib xws nrog ntau hom xim thiab txheej, kom ntseeg tau tias muaj kev sib txuas zoo thiab ruaj khov mus sij hawm ntev ntawm lub txheej txheej saum toj kawg nkaus.
VOC Qis: Cov pa phem ntawm cov organic compound (VOC) los ntawm cov hmoov putty yuav tsum tau txo kom tsawg kawg nkaus kom txo tau qhov cuam tshuam rau ib puag ncig thiab tswj tau qhov zoo ntawm huab cua hauv tsev.
3. Cov qauv zoo thiab kev sim:
Yuav kom ntseeg tau tias cov hmoov putty ua tau raws li qhov yuav tsum tau ua thiab cov qauv kev ua tau zoo, cov chaw tsim khoom feem ntau ua raws li cov cai ntawm kev lag luam thiab ua kev sim nruj. Cov kev ntsuas tswj xyuas zoo feem ntau suav nrog:
Kev tshuaj xyuas qhov loj ntawm cov khoom me me: Sim qhov zoo ntawm cov hmoov siv cov txheej txheem xws li laser diffraction lossis sieve analysis.
Kev sim nplaum: Soj ntsuam lub zog sib txuas ntawm cov putty rau ntau yam substrates los ntawm kev sim rub lossis kev sim daim kab xev.
Kev Ntsuas Qhov Ntsws: Ntsuas qhov kev hloov pauv ntawm cov putty thaum lub sijhawm ziab kom paub txog cov yam ntxwv ntawm qhov ntsws.
Kev Ntsuas Kev Tiv Thaiv Dej: Cov qauv yuav raug rau hauv dej los yog chav ntsuas av noo kom ntsuas kev tiv thaiv av noo.
Kev ntsuam xyuas lub sijhawm ziab: Saib xyuas cov txheej txheem ziab raws li cov xwm txheej tswj tau kom paub lub sijhawm uas xav tau kom qhuav tag.
Kev Ntsuas Kev Tiv Thaiv Kev Tawg: Cov vaj huam sib luag uas muaj putty raug rau kev simulated environmental pressures los ntsuas qhov tawg thiab kev nthuav dav.
Kev Ntsuas Kev Sib Xws: Soj ntsuam qhov sib xws nrog cov xim thiab cov tshuaj pleev xim los ntawm kev siv rau saum cov putty thiab soj ntsuam qhov lo thiab qhov zoo ntawm kev ua tiav.
Kev Tshuaj Xyuas VOC: Siv cov txheej txheem txheem los ntsuas qhov ntau ntawm cov pa phem VOC kom ntseeg tau tias ua raws li cov kev txwv ntawm txoj cai.
Los ntawm kev ua raws li cov qauv zoo no thiab ua qhov kev sim ua kom tiav, cov chaw tsim khoom tuaj yeem tsim cov putties uas ua tau raws li qhov yuav tsum tau ua thiab muab kev ua tau zoo hauv ntau yam kev tsim kho thiab kev ua tiav.
Cov yam ntxwv ntawm cov hmoov putty yog xws li nws ua tau zoo rau qhov tsis zoo thiab muab ib qho chaw du rau kev pleev xim lossis ua tiav. Cov chaw tsim khoom yuav tsum xav txog cov khoom sib xyaw thiab cov qauv ntawm cov hmoov putty kom ntseeg tau tias nws qhia txog cov yam ntxwv xav tau xws li kev nplaum, kev ua haujlwm tau zoo, kev tiv thaiv shrinkage thiab kev ruaj khov. Los ntawm kev ua raws li cov qauv zoo thiab kev sim ua tib zoo, cov hmoov putty zoo yog tsim los ua kom tau raws li qhov xav tau ntawm cov kws tshaj lij kev tsim kho thiab cov tswv tsev.
