Lub luag haujlwm ntawm cov hmoov latex hauv cov txheej txheem rwb thaiv tsev phab ntsa sab nraud thiab cov nplaum pobzeb

Cov txheej txheem rwb thaiv tsev sab nraud ntawm phab ntsa sab nraud yog muab ib lub tsho tiv thaiv cua sov rau ntawm lub tsev. Lub tsho tiv thaiv cua sov no tsis yog tsuas yog khaws cua sov xwb, tab sis kuj yuav tsum zoo nkauj thiab. Tam sim no, kuv lub teb chaws cov txheej txheem rwb thaiv tsev sab nraud feem ntau suav nrog cov txheej txheem rwb thaiv tsev polystyrene nthuav dav, cov txheej txheem rwb thaiv tsev polystyrene extruded, cov txheej txheem rwb thaiv tsev polyurethane, cov txheej txheem rwb thaiv tsev hmoov latex polystyrene, cov txheej txheem rwb thaiv tsev inorganic vitrified bead, thiab lwm yam. Cov txheej txheem rwb thaiv tsev sab nraud tsis yog tsuas yog tsim rau cov tsev sov hauv thaj chaw sab qaum teb uas xav tau kev txuag cua sov thaum lub caij ntuj no xwb, tab sis kuj rau cov tsev txias hauv thaj chaw sab qab teb uas xav tau kev rwb thaiv tsev thaum lub caij ntuj sov; nws tsim nyog rau ob qho tib si cov tsev tshiab thiab kev kho dua tshiab txuag hluav taws xob ntawm cov tsev uas twb muaj lawm; kev kho dua tshiab ntawm cov tsev qub.

① Cov txiaj ntsig ntawm kev ntxiv cov hmoov latex uas tau tawg ua tej daim me me rau hauv cov tshuaj khib sib xyaw tshiab ntawm lub kaw lus rwb thaiv tsev phab ntsa sab nraud:

A. Txuas ntxiv cov sijhawm ua haujlwm;

B. Txhim kho qhov kev ua haujlwm ntawm kev khaws dej kom ntseeg tau tias cov cement tau noo;

C. Txhim kho kev ua haujlwm tau zoo.

② Cov nyhuv ntawm kev ntxiv cov hmoov latex uas tau tawg ua tej daim me me rau ntawm cov mortar uas tawv ntawm lub tshuab rwb thaiv tsev phab ntsa sab nraud:

A. Zoo adhesion rau polystyrene board thiab lwm yam substrates;

B. Kev ywj pheej zoo heev thiab kev cuam tshuam tsis kam;

C. Cov dej ua pa zoo heev;

D. Kev hydrophobicity zoo;

E. Kev tiv thaiv huab cua zoo.

Qhov tshwm sim ntawm cov nplaum pobzeb, rau qee qhov, ua kom ntseeg tau tias cov nplaum pobzeb muaj kev ntseeg siab. Cov cwj pwm tsim kho sib txawv thiab cov txheej txheem tsim kho muaj cov kev cai ua haujlwm tsim kho sib txawv rau cov nplaum pobzeb. Hauv kev tsim kho pobzeb hauv tsev tam sim no, txoj kev nplaum tuab (cov nplaum nplaum ib txwm muaj) tseem yog txoj kev tsim kho tseem ceeb. Thaum siv txoj kev no, cov kev cai rau cov nplaum pobzeb: yooj yim do; yooj yim rau kev siv kua nplaum, riam tsis lo; viscosity zoo dua; zoo dua tiv thaiv kev plam. Nrog rau kev txhim kho ntawm cov thev naus laus zis nplaum pobzeb thiab kev txhim kho ntawm cov thev naus laus zis tsim kho, txoj kev trowel (txheej txheem nplaum nyias) kuj maj mam siv. Siv txoj kev tsim kho no, cov kev cai rau cov nplaum pobzeb: yooj yim do; riam nplaum; zoo dua tiv thaiv kev plam; zoo dua ntub rau pobzeb, lub sijhawm qhib ntev dua.

① Cov nyhuv ntawm kev ntxiv cov hmoov latex uas tawg tau rau ntawm cov tshuaj nplaum sib xyaw tshiab ntawm cov nplais pobzeb:

A. Ntev lub sijhawm ua haujlwm thiab lub sijhawm hloov kho tau;

B. Txhim kho qhov kev ua haujlwm ntawm kev khaws dej kom ntseeg tau tias cov cement tau noo;

C. Txhim kho kev tiv thaiv sag (hmoov latex hloov kho tshwj xeeb)

D. Txhim kho kev ua haujlwm tau zoo (yooj yim rau kev tsim kho ntawm lub substrate, yooj yim rau nias lub pobzeb rau hauv cov nplaum).

② Cov nyhuv ntawm kev ntxiv cov hmoov latex uas tawg tau rau ntawm cov pob zeb nplaum uas ua kom tawv:

A. Nws muaj kev nplaum zoo rau ntau yam khoom siv, suav nrog cov pob zeb ua vaj tse, plaster, ntoo, cov vuas qub, PVC;

B. Nyob rau hauv ntau yam huab cua, nws muaj kev hloov pauv zoo.
