Ar Cov caws pliav tsis zoo: Redispersible latex hmoov ua kom lub zog muaj zog rau txhua qhov chaw qis, txo cov txheej txheem elastic, nce dej kom ruaj khov, txo cov dej nkag, thiab muab cov khoom lag luam nrog kev hloov pauv siab, huab cua tsis kam thiab siab dej siab yuav tsum tau ua. Nws muaj lub txiaj ntsig ntev ntev ntawm kev sib khi nrog lub siab xav tau ntawm cov dej tsis kam thiab dej tsis kam.

Ar Lub pob zeb thaiv sab nrauv sab nrauv: Redispersible emulsion hmoov nyob rau sab nrauv phab ntsa sab nrauv txheej txheem rwb thaiv tsev txhim kho txoj kev sib haum xeeb ntawm cov cug thiab cov hlua khi rau cov rwb thaiv tsev, kom koj tuaj yeem nrhiav cov rwb thaiv tsev thaum txo kev siv zog. Yuav kom ua tiav qhov kev ua haujlwm tsim nyog, ua kom muaj lub zog thiab hloov tau yooj yim hauv cov cuab yeej siv thaiv phab ntsa sab nraud, koj tuaj yeem ua koj cov khoom siv cug muaj qhov ua tiav zoo nrog rau cov khoom siv rwb thaiv tsev thiab lub hauv paus. Nyob rau tib lub sijhawm, nws tseem pab txhim kho qhov cuam tshuam tiv thaiv thiab tiv thaiv kev tawg xim.

◆ Kho Cov Cug: Redispersible latex hmoov muaj qhov yuav tsum tau ua kom yooj yim, txo qis, siab cohesiveness, haum flexural thiab tensile lub zog. Ua kho pob cug tau ua tiav raws li qhov xav tau saum toj no rau kev kho vaj tse thiab txheej txheem pob zeb tsis zoo.

Face Kev cuam tshuam cov tshuaj khib: Redispersible latex hmoov yog tsuas yog siv los kho lub pob zeb saum npoo av, aerated pob zeb, kua av xuab zeb thiab ya cov hmoov av cib, thiab lwm yam, los daws qhov teeb meem uas qhov interface tsis yooj yim los lo vim muaj dej ntau dhau lossis ua rau du. , thiab plaster txheej khoob. Nruas, nrib pleb, nti, thiab lwm yam Nws ua kom lub nplaum ruaj khov, tsis yooj yim kom poob tawm thiab dej tsis kam, thiab zoo heev khov-kuab kuj. Nws muaj cov nyhuv tseem ceeb ntawm kev ua haujlwm yooj yim, kev tsim kho tau yooj yim.

Redispersible hmoov feem ntau yog siv hauv:

Sab hauv thiab txheej sab nrauv phab ntsa putty hmoov, pob zeb nplaum, pob zeb sib koom nrog tus neeg sawv cev, qhuav hmoov interface tus neeg sawv cev, cov cuab yeej tshuaj thaiv phab ntsa sab nrauv, nws tus kheej qib caws, kho tshuaj khib, kho hniav caws, tshuaj khib dej hauv hluav taws xob sab nraud thermal rwb thaiv tsev qhuav-sib xyaw cov tshuaj khib. Txhua yam ntawm lub tshuaj khib siv los txhim kho lub brittleness thiab siab elastic modulus ntawm tsoos cement mortars, thiab kom lawv zoo dua yooj thiab tensile daim ntawv cog lus lub zog los tiv thiab ncua lub cim ntawm cov nrib pleb hauv cov cement mortars. Vim tias lub polymer thiab tshuaj khib tsim cov txheej txheem ua ntu nrog network, ib zaj duab xis nruam polymer yog tsim nyob rau hauv lub qhov hws, uas ntxiv dag zog rau kev sib khi ntawm qhov kev sib xyaw thiab thaiv qee qhov pores hauv lub tshuaj khib. Yog li ntawd, hloov kho dua tshiab tom qab cov qhov txhab muaj qhov ua tau zoo dua li cov nplai cug. Muaj tau muaj kev txhim kho zoo.
