Qhov sib ntxiv ntawm polymer additives rau mortars yog ib qho kev coj ua hauv kev tsim kho thiab masonry los txhim kho kev ua tau zoo thiab kev ua haujlwm ntawm cov mortars. Polymer additives yog cov khoom sib xyaw rau hauv cov tshuaj khib nyiab los txhim kho nws cov haujlwm ua haujlwm, adhesion, yooj, durability thiab lwm yam khoom tseem ceeb. Tus nqi ntawm cov khoom siv polymer ntxiv rau hauv mortar tuaj yeem sib txawv nyob ntawm seb hom polymer tshwj xeeb, cov khoom xav tau ntawm mortar, thiab cov chaw tsim khoom cov lus pom zoo.

Hom ntawm polymer additives:

1.Redispersible polymer hmoov (RDP):
Muaj nuj nqi: RDP feem ntau yog siv los txhim kho qhov adhesion, yoog raws thiab ua haujlwm ntawm mortars.
Dosage: Feem ntau 1-5% ntawm tag nrho qhov hnyav qhuav ntawm mortar mix.

2. Latex polymer additives:
Muaj nuj nqi: Latex additives txhim kho qhov yooj, adhesion thiab dej tsis kam ntawm mortar.
Kev Siv: 5-20% ntawm cov cement hnyav, nyob ntawm seb cov latex polymer tshwj xeeb.

3. Cellulose ether:
Muaj nuj nqi: Txhim kho dej tuav, ua haujlwm tau zoo, thiab txo qis hauv kev siv ntsug.
Kev Siv: 0.1-0.5% ntawm cement hnyav.

4. SBR (styrene-butadiene roj hmab) latex:
Function: Txhim kho adhesion, yooj thiab durability.
Kev Siv: 5-20% ntawm cement hnyav.

5. Acrylic polymer:
Function: Txhim kho adhesion, dej tsis kam, durability.
Kev Siv: 5-20% ntawm cement hnyav.

Cov lus qhia rau kev ntxiv polymer additives rau mortars:

1. Nyeem cov chaw tsim khoom cov lus qhia:
Nco ntsoov xa mus rau cov chaw tsim khoom cov lus qhia thiab cov ntaub ntawv kev qhia txog cov lus pom zoo ntawm polymer additive hom thiab ntau npaum li cas.

2. Kev sib xyaw ua ke:
Ntxiv cov polymer additive rau cov dej los yog sib tov nrog cov tshuaj khib nyiab qhuav ua ntej ntxiv dej. Ua raws li cov txheej txheem sib xyaw ua ke kom ntseeg tau tias muaj kev cuam tshuam zoo.

3. Kev tswj kev noj tshuaj:
Ntsuas ntsuas cov polymer additives kom tau txais cov khoom xav tau. Cov nyiaj ntau dhau tuaj yeem cuam tshuam tsis zoo rau kev ua haujlwm mortar.

4.Compatibility xeem:
Ua kev ntsuas kev sib raug zoo ua ntej siv cov khoom siv polymer tshiab los xyuas kom meej tias nws tsis cuam tshuam nrog lwm cov khoom xyaw hauv cov tshuaj khib nyiab.

5. Kho raws li ib puag ncig:
Nyob rau hauv huab cua huab cua, xws li qhov kub thiab txias los yog cov av noo tsawg, yuav tsum tau hloov cov tshuaj noj kom zoo.

6. Kev sim ntawm qhov chaw:
Kev ntsuam xyuas teb tau ua los ntsuas qhov ua tau zoo ntawm cov khoom siv polymer-hloov kho raws li lub ntiaj teb tiag tiag.

7. Ua raws li cov cai hauv tsev:
Xyuas kom tseeb tias cov khoom siv polymer yog siv ua raws li cov cai hauv zos thiab cov cai.

8. Kev txiav txim siab ntawm daim ntawv thov:
Hom kev thov (xws li flooring, vuas, plastering) tuaj yeem cuam tshuam rau kev xaiv thiab ntau npaum li cas ntawm cov khoom siv polymer.

nyob rau hauv xaus:
Tus nqi ntawm cov khoom siv polymer ntxiv rau hauv mortar yog nyob ntawm ntau yam, nrog rau hom polymer, cov khoom xav tau thiab cov chaw tsim khoom cov lus pom zoo. Ua tib zoo saib xyuas, ua raws li cov lus qhia thiab kev sim tsim nyog yog qhov tseem ceeb kom tau txais cov txiaj ntsig zoo tshaj plaws. Nco ntsoov sab laj nrog cov chaw tsim khoom thiab ua raws li cov kev coj ua zoo tshaj plaws kom ntseeg tau tias muaj kev vam meej ntawm kev siv polymer-hloov mortar hauv kev tsim kho thiab masonry.
