1. Putty yog siv los ua cov khoom siv rau kev kho ua ntej ntawm qhov chaw uas yuav tsum tau coated hauv architectural coatings
Putty yog ib txheej nyias nyias ntawm cov mortar leveling. Putty raug khawb rau ntawm qhov chaw ntawm cov substrates ntxhib (xws li concrete, leveling mortar, gypsum board, thiab lwm yam). Ua kom cov xim phab ntsa sab nraud du thiab mos, tsis yooj yim rau khaws cov hmoov av thiab yooj yim los ntxuav (qhov no tseem ceeb dua rau cov chaw uas muaj huab cua phem dua). Putty tuaj yeem muab faib ua ib feem putty (paste putty paste thiab hmoov qhuav putty hmoov) thiab ob feem putty (muaj hmoov putty thiab emulsion) raws li cov khoom tiav. Nrog rau tib neeg txoj kev saib xyuas rau cov txheej txheem kev tsim kho vaj tse, putty ua cov khoom txhawb nqa tseem ceeb kuj tau tsim raws li. Ntau lub tuam txhab tsim khoom hauv tsev tau tsim cov putty nrog ntau lub hom phiaj thiab ntau yam duab, xws li hmoov putty, paste putty, sab hauv phab ntsa putty Putty, sab nraud phab ntsa putty, elastic putty, thiab lwm yam.
Los ntawm kev siv cov txheej txheem vaj tse hauv tsev tiag tiag, feem ntau muaj qhov tsis zoo xws li ua npuas dej thiab tev tawm, uas cuam tshuam loj heev rau kev tiv thaiv thiab kho kom zoo nkauj ntawm cov txheej txheem ntawm cov tsev. Muaj ob qho laj thawj tseem ceeb rau kev puas tsuaj ntawm cov zaj duab xis txheej:
Ib qho yog qhov zoo ntawm cov xim;
Qhov thib ob yog kev tswj tsis zoo ntawm lub substrate.
Kev xyaum tau qhia tias ntau tshaj 70% ntawm cov txheej txheem tsis ua haujlwm yog cuam tshuam nrog kev tswj hwm cov khoom tsis zoo. Cov putty rau cov txheej txheem architectural tau siv dav ua cov khoom siv raw rau kev kho qhov chaw ua ntej kom pleev xim. Nws tsis tsuas yog tuaj yeem ua kom du thiab kho qhov chaw ntawm cov tsev, tab sis kuj tseem tuaj yeem txhim kho kev tiv thaiv thiab kho kom zoo nkauj ntawm cov txheej txheem ntawm cov tsev. Kev ncua lub neej ua haujlwm ntawm cov txheej txheem yog ib qho khoom txhawb nqa tseem ceeb rau cov txheej txheem architectural ua tau zoo, tshwj xeeb tshaj yog cov txheej txheem phab ntsa sab nraud. Cov hmoov qhuav putty ib qho muaj txiaj ntsig zoo rau kev lag luam, kev siv tshuab thiab ib puag ncig hauv kev tsim khoom, kev thauj mus los, kev khaws cia, kev tsim kho thiab lwm yam.
Lus Cim: Vim muaj tej yam xws li cov khoom siv raw thiab tus nqi, cov hmoov polymer dispersible feem ntau yog siv rau hauv cov hmoov putty tiv thaiv kev tawg rau phab ntsa sab nraud, thiab kuj siv rau hauv cov khoom siv polishing phab ntsa sab hauv qib siab.
2. Lub luag haujlwm ntawm cov tshuaj pleev thaiv kev tawg rau phab ntsa sab nraud
Feem ntau cov cement ua cov khoom siv sib txuas inorganic, thiab me ntsis calcium tshauv tuaj yeem ntxiv rau kom ua tiav cov txiaj ntsig synergistic. Lub luag haujlwm ntawm cov cement-based anti-cracking putty rau phab ntsa sab nraud:
Cov txheej txheem putty muab qhov chaw zoo rau saum npoo, uas txo cov xim thiab txo cov nqi ntawm qhov project;
Putty muaj kev nplaum zoo thiab tuaj yeem txuas tau zoo rau phab ntsa hauv qab;
Nws muaj qee qhov kev tawv, tuaj yeem tiv thaiv cov teebmeem ntawm kev nthuav dav thiab kev ntxhov siab ntawm cov txheej txheem sib txawv, thiab muaj kev tiv thaiv tawg zoo;
Putty muaj kev tiv thaiv huab cua zoo, tsis muaj dej nkag, tiv thaiv dej noo thiab lub sijhawm ua haujlwm ntev;
Tus phooj ywg ib puag ncig, tsis muaj tshuaj lom thiab muaj kev nyab xeeb;
Tom qab kev hloov kho ntawm cov khoom siv ntxiv, xws li hmoov roj hmab putty thiab lwm yam khoom siv, cov phab ntsa sab nraud putty kuj tseem tuaj yeem muaj cov txiaj ntsig ntxiv hauv qab no:
Kev ua haujlwm ntawm kev khawb ncaj qha rau ntawm cov khoom tiav qub (xim, pobzeb, mosaic, pob zeb thiab lwm yam phab ntsa du);
Zoo thixotropy, ib qho chaw du zoo meej tuaj yeem tau txais los ntawm kev tsuas yog smearing, thiab qhov poob los ntawm ntau yam kev siv coatings vim yog qhov tsis sib xws ntawm lub hauv paus yog txo qis;
Nws yog elastic, tuaj yeem tiv taus cov kab nrib pleb me me, thiab tuaj yeem them rov qab qhov puas tsuaj ntawm kev ntxhov siab kub;
Zoo dej repellent thiab waterproof function.
3. Lub luag haujlwm ntawm cov hmoov latex uas tau tawg ua dua tshiab hauv cov hmoov putty sab nraud ntawm phab ntsa
(1) Cov nyhuv ntawm cov hmoov roj hmab putty rau cov putty sib xyaw tshiab:
Txhim kho kev ua haujlwm tau zoo thiab txhim kho kev ua haujlwm ntawm cov khoom siv putty batch scraping;
kev khaws dej ntxiv;
ua haujlwm tau zoo dua;
Tsis txhob tawg ua tej daim me me thaum ntxov.
(2) Cov nyhuv ntawm cov hmoov roj hmab putty rau ntawm cov putty tawv:
Txo qhov elastic modulus ntawm putty thiab txhim kho qhov sib phim rau txheej puag;
Txhim kho cov qauv micro-pore ntawm cov cement, ua kom muaj kev ywj pheej tom qab ntxiv cov hmoov roj hmab putty, thiab tiv taus kev tawg;
Txhim kho cov hmoov tsis kam;
Hydrophobic los yog txo qhov nqus dej ntawm cov txheej putty;
Ua kom qhov nplaum ntawm cov putty rau ntawm phab ntsa hauv paus.
Plaub, qhov yuav tsum tau ua ntawm cov txheej txheem tsim kho phab ntsa sab nraud
Cov txheej txheem tsim kho putt yuav tsum tau them sai sai rau:
1. Qhov cuam tshuam ntawm cov xwm txheej kev tsim kho:
Qhov cuam tshuam ntawm cov xwm txheej kev tsim kho feem ntau yog qhov kub thiab txias ntawm ib puag ncig. Hauv huab cua kub, txheej hauv paus yuav tsum tau txau dej kom zoo, lossis khaws cia kom ntub, nyob ntawm qhov ua tau zoo ntawm cov khoom siv hmoov putty tshwj xeeb. Vim tias cov hmoov putty phab ntsa sab nraud feem ntau siv cement ua cov khoom siv cementitious, qhov kub thiab txias ib puag ncig yuav tsum tsis txhob qis dua 5 degrees, thiab nws yuav tsis khov ua ntej khov tom qab kev tsim kho.
2. Kev npaj thiab kev ceev faj ua ntej khawb cov putty:
Yuav tsum tau ua tiav qhov project tseem ceeb, thiab lub tsev thiab lub ru tsev tau ua tiav lawm;
Yuav tsum tau teeb tsa txhua qhov chaw, qhov rooj, qhov rai thiab cov kav dej ntawm lub hauv paus tshauv;
Txhawm rau tiv thaiv kev ua qias tuaj thiab kev puas tsuaj rau cov khoom tiav hauv cov txheej txheem khawb ntau ntau, cov khoom tiv thaiv tshwj xeeb thiab kev ntsuas yuav tsum tau txiav txim siab ua ntej khawb ntau ntau, thiab cov khoom cuam tshuam yuav tsum tau npog thiab qhwv;
Lub installation ntawm lub qhov rais yuav tsum tau ua tom qab lub putty batch raug scraped.
3. Kev kho qhov chaw:
Qhov saum npoo ntawm lub substrate yuav tsum ruaj khov, tiaj tus, qhuav thiab huv si, tsis muaj roj, batik thiab lwm yam khoom xoob;
Qhov saum npoo ntawm cov plastering tshiab yuav tsum tau kho rau 12 hnub ua ntej cov putty tuaj yeem khawb tau, thiab cov txheej plastering qub tsis tuaj yeem calendered nrog cov cement paste;
Yog tias phab ntsa qhuav dhau ua ntej kev tsim kho, phab ntsa yuav tsum tau ntub ua ntej.
4. Cov txheej txheem ua haujlwm:
Ncuav dej kom txaus rau hauv lub thawv, tom qab ntawd ntxiv cov hmoov putty qhuav, thiab tom qab ntawd do tag nrho nrog lub tshuab sib tov kom txog thaum nws yog cov nplaum sib xws tsis muaj cov hmoov me me thiab nag lossis daus;
Siv cov cuab yeej khawb ib pawg rau kev khawb ib pawg, thiab qhov thib ob ntawm kev khawb ib pawg tuaj yeem nqa tawm tom qab thawj txheej ntawm kev ntxig ib pawg tiav rau li 4 teev;
Khawb cov txheej putty kom du, thiab tswj cov tuab kom txog li 1.5 hli;
Cov cement-based putty tuaj yeem pleev xim nrog alkali-resistant primer tsuas yog tom qab kev kho kom zoo nkauj ntuj tau ua tiav kom txog thaum alkalinity thiab lub zog ua tau raws li qhov yuav tsum tau ua;
5. Cov Lus Cim:
Yuav tsum txiav txim siab qhov ntsug thiab qhov tiaj tiaj ntawm lub substrate ua ntej kev tsim kho;
Cov tshuaj mortar sib xyaw yuav tsum tau siv tsis pub dhau 1 ~ 2 teev (nyob ntawm tus qauv);
Tsis txhob sib tov cov putty mortar uas tau siv dhau lub sijhawm siv nrog dej ua ntej siv;
Nws yuav tsum tau polished tsis pub dhau 1 ~ 2 hnub;
Thaum lub hauv paus ntawm lub hauv paus raug calendered nrog cement mortar, nws raug pom zoo kom siv cov neeg sawv cev kho interface lossis interface putty thiab elastic putty.
Qhov ntau npaum li cas ntawmhmoov polymer uas yaj tau dua tshiabtuaj yeem xa mus rau cov ntaub ntawv ntau npaum li cas hauv cov mis ntawm cov hmoov putty sab nraud phab ntsa. Nws raug pom zoo kom cov neeg siv khoom ua ntau qhov kev sim me me ua ntej tsim ntau yam kom ntseeg tau tias cov hmoov putty zoo.
