Lub luag haujlwm ntawm cov hmoov latex uas tawg tau dua tshiab hauv kev lag luam kev tsim kho tsis tuaj yeem raug kwv yees qis. Raws li cov khoom siv ntxiv uas siv dav tshaj plaws, nws tuaj yeem hais tias qhov tsos ntawm cov hmoov latex uas tawg tau tau tsa qhov zoo ntawm kev tsim kho ntau dua ib qib. Cov khoom tseem ceeb ntawm cov hmoov latex yog cov organic macromolecular polymer nrog cov khoom ruaj khov. Tib lub sijhawm, PVA ntxiv rau ua cov colloid tiv thaiv. Nws feem ntau yog hmoov ntawm chav tsev kub. Lub peev xwm lo yog muaj zog heev thiab kev ua haujlwm tsim kho kuj zoo heev. Tsis tas li ntawd, cov hmoov latex no tuaj yeem txhim kho qhov kev tiv thaiv hnav thiab kev nqus dej ntawm phab ntsa los ntawm kev txhim kho lub zog sib koom ua ke ntawm cov mortar. Tib lub sijhawm, lub zog sib koom ua ke thiab kev hloov pauv kuj paub tseeb. qib ntawm kev txhim kho.
Lub luag haujlwm ntawm cov hmoov latex redispersible hauv cov mortar ntub:
(1) Txhim kho qhov khaws dej ntawm cov mortar;
(2) Ntev lub sijhawm qhib ntawm cov mortar;
(3) Txhim kho qhov sib koom ua ke ntawm cov mortar;
(4) Ua kom cov thixotropy thiab sag tsis kam ntawm mortar;
(5) Txhim kho qhov fluidity ntawm mortar;
(6) Txhim kho kev ua tau zoo ntawm kev tsim kho.
Lub luag haujlwm ntawm cov hmoov latex uas rov ua dua tom qab cov tshuaj khib kho tau:
(1) Txhim kho lub zog khoov;
(2) Txhim kho lub zog tensile;
(3) Kev hloov pauv ntau ntxiv;
(4) Txo qhov modulus ntawm elasticity;
(5) Txhim kho lub zog sib koom ua ke;
(6) Txo qhov tob ntawm carbonization;
(7) Ua kom cov khoom siv ntom ntom dua;
(8) Txhim kho kev hnav tsis kam;
(9) Txo qhov nqus dej ntawm cov khoom siv;
(10) Ua kom cov khoom muaj cov dej tsis zoo.
