Tshuaj Tiv Thaiv:Tiv thaiv kev loj hlob microbial, txuas ntxiv rau lub neej.
Tsim Tsim Txheej Txheem Txheej Txheem
Sib tov qhuav:
Muab cov tshuaj calcium carbonate, talcum hmoov, thiab hydrated txiv qaub kom huv.
Ntxiv cov cement dawb thiab sib tov rau kev sib xyaw.
Txuas ntxiv ntawm kev ua haujlwm ntxiv:
Ua kom paub cov neeg sawv cev tawg (PVA, fiberglass hmoov) thiab sib tov tusyees.
Teeb meem polymer polymer (RDP) thiab cov neeg sawv cev dej uas muaj dej ntws (ua si).
Kev sib xyaw ua ke kawg:
Ntxiv HPMC, Warch ether, defoober, thiab txuag tshuaj pov tseg.
Xyuas kom meej pem kev sib xyaw rau tsawg kawg yog 15-20 feeb rau kev faib tawm cov khoom sib txuam.
Ntim:
Khaws rau hauv cov dej noo-pov thawj ntim kom muaj qhov zoo.
Cov yam ntxwv ua tau zoo
| Ntiag tug | Cov Qauv Xav Tau |
| Tawg | Tsis pom cov tawg tom qab ziab |
| Dej ragentit | ≤ 5% |
| Adhesion lub zog | ≥ 1.0 MPA (tom qab kho) |
| Kev ua haujlwm | Du, yooj yim mus sib kis |
| Txee lub neej | 6-12 hlis (hauv cov xwm txheej qhuav) |
Cov Lus Qhia Thov
Npaj Kev Npaj Deg:
Ua kom cov phab ntsa yog huv si, qhuav, thiab pub dawb los ntawm hmoov av, roj, lossis cov ntaub ntawv xoob.
Kho cov kab nrib pleb thiab qhov ua ntej thov.
Nws:
Sib tov kev sib xyaw nrog cov dej huv (pom zoo) piv txwv: 1: 0.4-0.5).
Do kom zoo kom txog thaum tus paste du ua tiav.
Daim Ntawv Thov:
Thov nrog tus trowel steel hauv nyias txheej (1-2 hli ib lub tsho tiv no).
Tso cai rau txhua txheej kom qhuav ua ntej thov rau tom ntej.
Kho:
Maim Ceeb rau saum npoo rau 1-2 hnub los txhim kho lub zog thiab tiv thaiv kev tawg.
Qhov kev tiv thaiv no tawg thiab tiv thaiv cov hmoov nplaum putty yog tsim los muab cov adhesion zoo heev, thiab kav ntev rau phab ntsa sab nrauv. Los ntawm cov kev xaiv ua tib zoo xaiv thiab ntsuas txhua qhov ua tau, lub putty kom paub ntev ntev, du, thiab tiv thaiv txheej. Kev npaj kom tsim nyog thiab daim ntawv thov yuav ntxiv txhim kho kev ua tau zoo ntawm lub putty, ua nws txoj kev xaiv txhim khu kev qha rau sab nrauv sau.
