Cov hmoov tshauv ntawm redispersible polymer hmoov (RDP) yog qhov tseem ceeb tsis zoo uas cuam tshuam rau lawv cov kev ua tau zoo hauv ntau yam kev siv, tshwj xeeb tshaj yog nyob rau hauv kev tsim kho kev lag luam. Txawm hais tias ib tus neeg yuav xav tias cov ntsiab lus qis dua yog qhov zoo dua, nws yog ib qho tseem ceeb kom nkag siab txog lub luag haujlwm ntawm cov hmoov tshauv hauv RDP cov khoom thiab kev ua haujlwm.
Kawm txog Redispersible Polymer Powder (RDP):
RDP yog cov hmoov hluavtaws hluavtaws uas tsim cov yeeb yaj kiab zoo ib yam li cov polymer qub thaum tov nrog dej. Nws yog dav siv nyob rau hauv kev tsim kho daim ntaub ntawv xws li mortar thiab pob zeb los txhim kho lawv cov khoom. RDP yog muab los ntawm emulsion polymerization ntawm ntau hom monomers, xws li yas acetate, ethylene thiab acrylates.
Lub ntsiab lus ntawm cov hmoov tshauv:
Cov ntsiab lus tshauv yog hais txog cov inorganic residue tshuav tom qab ib qho qauv raug hlawv. Hauv RDP, cov ntsiab lus tshauv feem ntau yog cuam tshuam nrog cov khoom seem ntawm cov zaub mov thiab lwm yam khoom siv tsis zoo hauv cov polymer. Kev txiav txim siab ntawm cov ntsiab lus tshauv yog qhov tseem ceeb vim tias nws cuam tshuam rau kev ua haujlwm ntawm polymer nyob rau hauv cov nqe lus ntawm dispersion, tsim zaj duab xis thiab tag nrho cov zoo.
Cov ntsiab lus qis qis: qhov zoo
Txhim kho dispersion:
Cov hmoov tshauv qis feem ntau cuam tshuam nrog kev sib cais zoo dua hauv dej. Qhov no yog ib qho tseem ceeb rau RDP vim nws yuav tsum tau tsim kom muaj kev ruaj ntseg dispersion thaum tov nrog dej kom ntseeg tau tias txawm faib nyob rau hauv lub mortar los yog qhob mix.
Txhim khu kev tsim zaj duab xis:
Cov hmoov tshauv qis qis pab tsim cov yeeb yaj kiab zoo sib xws thiab hloov tau yooj yim. Qhov no pab txhim kho adhesion thiab cohesion ntawm cov khoom siv hauv tsev kawg.
Txo cov dej xav tau:
RDPs nrog cov hmoov tshauv qis dua tuaj yeem xav tau dej tsawg dua rau kev rov ua dua tshiab. Qhov no yog qhov zoo rau cov formulations uas cov ntsiab lus dej yuav tsum tau txo qis kom ua tiav cov khoom xav tau.
Txhim kho mechanical zog:
Cov hmoov tshauv qis dua tuaj yeem ua rau muaj txiaj ntsig zoo ntawm cov khoom siv hauv tsev kawg. Qhov no suav nrog kev txhim kho tensile zog, yooj thiab durability.
Txo cov huab cua:
Efflorescence, deposition ntawm soluble ntsev nyob rau saum npoo ntawm cov khoom, tuaj yeem txo qis los ntawm cov hmoov tshauv qis. Qhov no yog qhov tseem ceeb rau kev tswj kom zoo nkauj thiab kev ncaj ncees ntawm cov khoom siv hauv tsev.
Cov ntsiab lus tshauv siab dua: xav txog
Kev xav txog tus nqi:
Kev tsim cov txheej txheem uas ua tiav cov ntsiab lus qis qis yuav raug nqi ntau dua. Yog li ntawd, muaj kev sib pauv ntawm kev ua tiav qhov xav tau kev ua tau zoo thiab kev siv nyiaj zoo.
Daim ntawv thov tshwj xeeb:
Nyob ntawm daim ntawv thov, qee cov formulations tuaj yeem zam cov hmoov tshauv ntau dua yam tsis muaj kev cuam tshuam rau kev ua haujlwm. Hauv qhov no, kev txheeb xyuas qhov txiaj ntsig ntawm tus nqi yog qhov tseem ceeb hauv kev txiav txim siab cov ntsiab lus ntawm cov hmoov tshauv.
Txoj Cai Ua Raws Cai:
Cov cheeb tsam sib txawv tuaj yeem muaj cov kev cai tshwj xeeb lossis cov qauv rau qhov siab tshaj plaws tso cai cov hmoov tshauv ntawm cov khoom siv hauv tsev. Kev ua raws li cov qauv no yog qhov tseem ceeb rau kev lees paub hauv khw.
Optimization thiab kev tswj kom zoo:
Txhawm rau tawm tsam qhov kev sib npaug ntawm cov txiaj ntsig thiab muaj peev xwm txwv cov ntsiab lus tsis tshua muaj tshauv, cov tuam txhab feem ntau koom nrog kev ua kom zoo dua qub thiab cov txheej txheem tswj kom zoo. Cov txheej txheem no suav nrog kev kho cov txheej txheem polymerization, siv cov ntaub ntawv zoo, thiab siv cov txheej txheem ua kom huv huv.
nyob rau hauv xaus:
Thaum cov hmoov tshauv qis dua hauv RDP feem ntau muaj ntau qhov zoo, cov kev cai tshwj xeeb ntawm daim ntawv thov yuav tsum raug txiav txim siab. Qhov zoo tshaj plaws tshauv cov ntsiab lus yuav txawv nyob ntawm seb yam xws li cov khoom uas yuav tsum tau ntawm cov khoom siv hauv tsev, kev txiav txim siab nqi thiab kev tswj xyuas. Cov neeg tsim khoom yuav tsum ua tib zoo sib npaug cov ntsiab lus no los tsim cov RDP zoo uas ua tau raws li cov kev xav tau sib txawv ntawm kev tsim kho kev lag luam. Kev nkag siab tiav ntawm kev sib cuam tshuam ntawm cov ntsiab lus tshauv thiab RDP cov khoom yog qhov tseem ceeb los ua kom ntseeg tau tias kev ua tiav ntawm kev tsim kho thiab kev siv lub neej ntev ntawm cov khoom siv.
