Redispersible latex hmoov yog lub ntsiab additive rau qhuav hmoov ua ntej sib tov mortar xws li cement-based los yog gypsum raws li mortar.
Redispersible latex hmoov yog macromolecular polymer lotion qhuav los ntawm cov tshuaj tsuag, uas sib sau ua ke los ntawm thawj 2um los ua 80-120um spherical hais. Vim hais tias saum npoo ntawm cov khoom no yog coated nrog ib qho inorganic anti nyuaj qauv hmoov, peb tau qhuav polymer hmoov. Lawv yog ib qho yooj yim rau ncuav thiab khaws cia rau hauv lub hnab hauv lub warehouse. Thaum cov hmoov tov nrog mortar nrog dej, cement los yog gypsum raws li cov khoom siv hauv paus, nws tuaj yeem rov ua dua, thiab cov khoom siv yooj yim (2um) yuav rov tsim ib lub xeev sib npaug rau cov latex qub, yog li nws hu ua redispersible latex hmoov.
Nws muaj zoo redispersibility. Thaum nws sib cuag nrog dej, nws yuav rov ua dua rau hauv cov tshuaj pleev, thiab nws cov khoom siv tshuaj zoo ib yam nrog cov tshuaj pleev ib ce qub. Los ntawm kev ntxiv cov kua roj hmab rov qab rau cov cement-based lossis gypsum raws li cov hmoov qhuav ua ntej sib xyaw mortar, ntau yam khoom ntawm cov tshuaj khib tuaj yeem txhim kho, xws li:
- Txhim kho qhov sib txuas thiab cohesion ntawm mortar.
- Txo cov dej nqus thiab elastic modulus ntawm cov khoom.
- Txhim khu lub zog flexural, cuam tshuam tsis kam, hnav tsis kam, thiab durability ntawm cov ntaub ntawv.
- Txhim kho kev tsim kho ntawm cov khoom siv, thiab lwm yam.
