Kev rwb thaiv tsev ntawm cov phab ntsa sab nraud yog muab lub tsho tiv thaiv thermal rau ntawm lub tsev. Lub tsho tiv no thermal rwb thaiv tsev yuav tsum tsis tsuas yog ua kom sov, tab sis kuj zoo nkauj. Tam sim no, kuv lub teb chaws sab nrauv phab ntsa rwb thaiv tsev feem ntau suav nrog nthuav dav polystyrene board rwb thaiv tsev, extruded polystyrene board rwb thaiv tsev system, polyurethane rwb thaiv tsev system, latex hmoov polystyrene particle rwb thaiv tsev, inorganic vitrified hlaws rwb thaiv tsev, thiab lwm yam. Sab nrauv thermal rwb thaiv tsev tsis yog tsim rau cua sov vaj tse nyob rau sab qaum teb cheeb tsam uas xav tau kev txuag hluav taws xob thaum lub caij ntuj no, tab sis kuj rau cov tsev cua txias nyob rau sab qab teb. uas xav tau cua sov rwb thaiv tsev nyob rau lub caij ntuj sov; nws tsim nyog rau ob lub tsev tshiab thiab kev txuag hluav taws xob kho dua tshiab ntawm cov tsev uas twb muaj lawm; kho tsev qub.
① Cov nyhuv ntawm kev ntxiv redispersible latex hmoov rau cov khoom sib xyaw tshiab ntawm cov phab ntsa sab nrauv:
A. Txuas sijhawm ua haujlwm;
B. Txhim kho cov dej tuav kev ua haujlwm kom ntseeg tau cov dej ntawm cov cement;
C. Txhim kho kev ua haujlwm.
② Cov nyhuv ntawm kev ntxiv redispersible latex hmoov ntawm lub hardened mortar ntawm sab nraud phab ntsa rwb thaiv tsev system:
A. Zoo adhesion rau polystyrene board thiab lwm yam substrates;
B. Zoo heev yooj thiab cuam tshuam tsis kam;
C. Cov dej vapor permeability zoo heev;
D. Zoo hydrophobicity;
E. Zoo huab cua tsis kam.
Qhov tshwm sim ntawm pobzeb nplaum, rau ib qho twg, kom ntseeg tau tias cov pobzeb muab tshuaj txhuam. Cov cwj pwm sib txawv ntawm kev tsim kho thiab kev tsim kho muaj qhov sib txawv ntawm kev tsim kho kev ua haujlwm rau cov nplais nplaum. Hauv kev tsim cov pobzeb hauv tsev tam sim no, cov txheej txheem tuab tuab (cov tshuaj nplaum ib txwm siv) tseem yog txoj hauv kev tsim kho. Thaum siv txoj kev no, qhov yuav tsum tau ua rau cov pobzeb nplaum: yooj yim rau do; yooj yim siv kua nplaum, tsis-stick riam; Zoo dua viscosity; zoo dua los tiv thaiv plam. Nrog rau kev tsim cov pobzeb nplaum thev naus laus zis thiab kev txhim kho ntawm kev tsim kho tshuab, trowel method (nyias paste method) kuj maj mam txais. Siv txoj kev tsim kho no, qhov yuav tsum tau ua rau pobzeb nplaum: yooj yim rau do; nplaum riam; zoo dua los tiv thaiv kev ua haujlwm; zoo dua wettability rau cov vuas, qhib lub sij hawm ntev.
① Cov nyhuv ntawm kev ntxiv redispersible latex hmoov rau ntawm cov khoom sib xyaw tshiab ntawm cov nplais nplaum:
A. Nthuav lub sijhawm ua haujlwm thiab lub sijhawm kho tau;
B. Txhim kho cov dej tuav kev ua haujlwm kom ntseeg tau cov dej ntawm cov cement;
C. Txhim kho sag kuj (tshwj xeeb hloov latex hmoov)
D. Txhim kho kev ua haujlwm (yooj yim tsim ntawm lub substrate, yooj yim nias lub pobzeb rau hauv cov nplaum).
② Cov nyhuv ntawm kev ntxiv redispersible latex hmoov rau ntawm cov pobzeb nplaum hardening mortar:
A. Nws muaj adhesion zoo rau ntau yam substrates, xws li pob zeb, plaster, ntoo, vuas qub, PVC;
B. Nyob rau hauv ntau yam climatic tej yam kev mob, nws muaj zoo adaptability.
