Yuav ua li cas redispersible latex hmoov txhim kho kev ua tau zoo ntawm mortar siab?

Redispersible latex hmoov yog ua los ntawm polymer emulsion los ntawm cov tshuaj tsuag kom qhuav, tov nrog dej hauv cov cement mortar, emulsified thiab dispersed hauv dej, thiab tom qab ntawd rov tsim ib qho polymer emulsion ruaj khov. Tom qab redispersible latex hmoov yog emulsified thiab dispersed nyob rau hauv dej, cov dej evaporates, tsim ib tug polymer zaj duab xis nyob rau hauv lub mortar, txhim kho cov khoom ntawm mortar.

Dab tsi ntawm mortar tuaj yeem txhim kho los ntawm redispersible latex hmoov?

1. Txhim kho qhov cuam tshuam, kev ua haujlwm thiab hnav tsis kam ntawm mortar

Lub mortar yog ntim nrog cov cement mortar pore kab noj hniav, lub compactness ntawm cement mortar yog txhim kho, thiab hnav tsis kam yog zoo dua. Nyob rau hauv qhov kev txiav txim ntawm kev quab yuam sab nraud, nws tuaj yeem ua rau kev so tsis muaj kev puas tsuaj.

2. Txhim kho qhov adhesion ntawm mortar siv

Cov hmoov polymer hmoov muaj cov nyhuv ntub dej, yog li ob qho tib si ntawm cov cement mortar tuaj yeem ntws ntawm nws tus kheej. Tsis tas li ntawd, cov hmoov roj hmab muaj cov nyhuv inducing gas.

3. Txhim kho qhov sib txuas compressive zog thiab cohesive quab yuam ntawm mortar

Raws li cov organic tshuaj nplaum, redispersible latex hmoov tuaj yeem tsim muaj zog compressive thiab compressive zog ntawm cov laug cam. Nws ua lub luag haujlwm tseem ceeb hauv kev sib txuas ntawm cov cement mortar thiab organic chemical raw cov ntaub ntawv (lub plab, extruded insulating foam board) thiab qhov chaw ntawm lub rooj tsavxwm ntxuav.

4. Txhim kho kev laus tiv thaiv ntawm mortar, tiv thaiv lub voj voog khov-thaw, thiab tiv thaiv cov cement mortar los ntawm kev tawg.

Redispersible latex hmoov yog ib qho thermoplastic resin nrog kev ua haujlwm zoo, uas tuaj yeem ua rau cov mortar cuam tshuam nrog kev puas tsuaj los ntawm cov cua sov sab nraud thiab qhov chaw txias, thiab tsim nyog kom tsis txhob tawg ntawm lub mortar vim qhov kub thiab txias.

5. Ua kom cov hydrophobicity ntawm mortar thiab txo cov dej noo

Lub redispersible latex hmoov yog demulsified nyob rau hauv cov cement mortar kab noj hniav thiab nto txheej, thiab cov ntaub ntawv polymer tsis yooj yim rau redisperse tom qab dej kho, thaiv cov dej nkag thiab txhim kho impermeability.
