Kev rwb rwb thaiv tsev sab nraud ntawm phab ntsa sab nraud yog muab tso rau lub tsho cua sov ntawm lub tsev. Qhov no thermal rwb thaiv tsev lub tsho tiv no yuav tsum tsis tsuas yog khaws cia kub, tab sis kuj tseem zoo nkauj. Tam sim no, kuv lub teb chaws sab nraud phab ntsa rwb thaiv tsev cov txheej txheem tsuas yog suav nrog Polystyrene Board System, thiab lwm yam. Sab nraud thermal rwb thaiv tsev yog tsis tsuas yog haum rau Kev ua cua sov nyob rau sab qaum teb uas xav tau kev kub kub hauv lub caij ntuj no, tab sis kuj yog cov tsev cua txias nyob rau lub caij ntuj sov nyob rau lub caij ntuj sov; Nws haum rau ob lub tsev tshiab thiab kev txuag hluav taws xob ntawm lub tsev uas twb muaj lawm; Kev kho cov tsev laus.
① Cov nyhuv ntawm kev ntxiv redispersible looj cov hmoov kom ua ke ntawm phab ntsa sab nraud ntawm phab ntsa sab nraud:
A. Txuas lub sijhawm ua haujlwm;
B. Txhim kho cov dej ua kom muaj kev ua tau zoo kom ntseeg tau tias cov hydration ntawm cov cement;
C. txhim kho kev ua haujlwm.
② Cov nyhuv ntawm kev ntxiv redispersible looj cov hmoov ntawm lub tawv tawv ntawm phab ntsa sab nraud rwb thaiv tsev:
A. Cov nplaum zoo rau polystyrene board thiab lwm yam substrates;
B. Kev yooj yim heev thiab cuam tshuam kev cuam tshuam;
C. Zoo tshaj dej vapor permeability;
D. Zoo hydrophobicity;
E. Cov huab cua zoo tsis kam.
Qhov tshwm sim ntawm cov nplais nplaum, rau qee yam, xyuas kom txoj kev ntseeg tau ntawm cov pobzeb paste. Kev siv kev kho sib txawv thiab cov qauv kev tsim kho muaj cov kev tsim kho kom sib txawv cov khoom ua paug. Nyob rau hauv cov vuas tam sim no ua kev tsim kho, cov tuab txhuam cov txheej txheem (cov khoom siv tsoos nplaum ib txwm) tseem yog txoj kev tsim qauv kev tsim kho. Thaum cov qauv no siv, qhov yuav tsum tau rau cov nplais nplaum nplaum: yooj yim mus do; yooj yim mus thov kua nplaum, tsis-tus riam; Zoo dua viscosity; Zoo dua los tiv thaiv plam. Nrog rau kev txhim kho ntawm cov nplais nplaum thev naus laus zis thiab kev txhim kho ntawm kev tsim kho thev naus laus zis, cov txheej txheem trowel (nyias muab coj los siv. Siv txoj kev tsim qauv no, cov cai rau cov nplaum nplaum: yooj yim mus do; Cov riam nplaum nplaum; zoo dua kev ua yeeb yam plam; Zoo dua Wettability rau cov vuas, lub sijhawm qhib ntev dua.
① Cov nyhuv ntawm kev ntxiv redispersible looj hmoov ntawm cov tshiab sib nphium ntawm cov pobzeb nplaum:
A. Txuas lub sijhawm ua haujlwm thiab kho tau lub sijhawm;
B. Txhim kho cov dej ua kom muaj kev ua tau zoo kom ntseeg tau tias cov hydration ntawm cov cement;
C. Kev txhim kho Sag tiv thaiv (tshwj xeeb hloov cov hmoov yas)
D. Txhim kho kev ua haujlwm (yooj yim los tsim ntawm cov txheej txheem, yooj yim rau nias cov pobzeb rau hauv cov nplaum).
② cuam tshuam ntawm kev ntxiv redispersible latex hmoov ntawm vais nplaum nplaum cug:
A. Nws muaj cov nplaum zoo rau ntau hom substrates, suav nrog cov pob zeb ua, plaster, cov vuas qub, PVC;
B. Nyob rau hauv ntau huab cua huab cua, nws muaj kev yoog tau zoo.
