RDP (redispersible polymer hmoov) ua lub luag haujlwm tseem ceeb hauv kev tsim cov phab ntsa putty. Phab ntsa putty yog cov hmoov dawb, cement-raws li cov hmoov zoo siv los muab kev sib tw, txawm tias lub hauv paus rau tha xim thiab kho cov phab ntsa sab hauv thiab sab nrauv. Qhov sib ntxiv ntawm RDP txhim kho ntau yam khoom ntawm phab ntsa putty, ua kom nws ruaj khov, tsim tau thiab tsim nyog rau kev siv sib txawv.
1. Taw qhia rau Redispersible Polymer Powder (RDP):
Redispersible polymer hmoov (RDP) yog ib tug copolymer ntawm yas acetate thiab ethylene los yog lwm yam unsaturated monomers. Nws yog tsim los ntawm cov tshuaj tsuag kom qhuav ntau yam polymer emulsions. RDP feem ntau yog siv los ua cov nplaum rau cov khoom siv hauv tsev vim nws cov yeeb yaj kiab zoo heev, kev ua kom zoo, ua kom yooj yim thiab dej tsis kam.
2. Nta ntawm RDP:
Kev tsim cov yeeb yaj kiab: RDP dries los ua ib zaj duab xis nyias, hloov tau yooj yim uas txhim kho lub zog thiab ua haujlwm ntawm phab ntsa putty.
Adhesion: RDP txhim kho adhesion ntawm phab ntsa putty rau ntau yam substrates xws li pob zeb, plaster, cib thiab ntoo.
Flexibility: Lub xub ntiag ntawm RDP muab cov phab ntsa putty saj zawg zog, tso cai rau nws los tiv thaiv me ntsis yam ntxwv txav tsis muaj cracking.
Kev Tiv Thaiv Dej: RDP txhim kho cov dej tsis kam ntawm phab ntsa putty, tiv thaiv dej nkag thiab kev puas tsuaj tom qab.
Kev ua haujlwm tau zoo: RDP txhim kho kev ua haujlwm ntawm phab ntsa putty los ntawm kev txhawb nqa daim ntawv thov thiab txo qis los yog poob thaum thov.
3.Lub luag haujlwm ntawm RDP hauv phab ntsa putty mis:
Binder: RDP yog siv los ua thawj binder hauv phab ntsa putty formulations los khi ntau yam ntawm cov khoom sib xyaw ua ke thiab muab kev sib koom ua ke.
Txhim kho adhesion: Qhov sib ntxiv ntawm RDP zoo txhim kho phab ntsa putty adhesion rau substrate, ua kom muaj kev ruaj khov thiab tiv thaiv tev lossis tev.
Ntxiv Flexibility: RDP muab phab ntsa putty yooj, tso cai rau nws hloov mus rau me me txav hauv substrate yam tsis muaj cracking los yog delaminating.
Kev Tiv Thaiv Dej: RDP txhim kho cov dej tsis kam ntawm phab ntsa putty, tiv thaiv qhov chaw hauv qab los ntawm kev puas tsuaj los ntawm cov dej noo thiab ua kom lub sijhawm ntev.
Txo Shrinkage: RDP pab txo qis qhov shrinkage ntawm phab ntsa putty tom qab nws qhuav, yog li txo qhov muaj feem ntawm cov kab nrib pleb los yog fissures tsim nyob rau hauv qhov chaw.
Txhim khu kev ua haujlwm zoo: Lub xub ntiag ntawm RDP txhim kho kev ua haujlwm ntawm phab ntsa putty, ua kom yooj yim sib tov, thov thiab kis tusyees mus rau saum npoo.
Txhim kho durability: Los ntawm imparting lub zog, yooj thiab dej tsis kam, RDP pab ua kom tag nrho cov kav ntev thiab ntev ntawm phab ntsa putty coatings.
4. Daim ntawv thov ntawm RDP phab ntsa putty:
Kev Npaj Nto: Ua ntej siv phab ntsa putty, saum npoo yuav tsum huv si, qhuav, thiab tsis muaj plua plav, roj, roj, thiab cov khoom xoob.
Mixing: Sib tov phab ntsa putty hmoov thiab dej nyob rau hauv cov proportions pom zoo kom tsim ib tug du, pob-dawb muab tshuaj txhuam. RDP pab xyuas kom muaj kev sib cais thiab kev ruaj ntseg ntawm cov khoom sib tov.
Daim ntawv thov: Siv ib rab riam los yog trowel los siv cov phab ntsa sib xyaw rau ntawm qhov chaw npaj, ua kom cov txheej nyias nyias.
Smoothing thiab Leveling: Siv rab riam los yog trowel kom du thiab qib ntawm cov phab ntsa siv kom ua tiav qhov kev xav tau.
Qhuav: Phab ntsa putty yuav tsum tau tso cai kom qhuav tag raws li cov chaw tsim tshuaj paus cov lus qhia ua ntej ntxiv nto los yog painting.
Redispersible polymer hmoov (RDP) yog ib qho tseem ceeb muaj nyob rau hauv phab ntsa putty formulations, pab txhim kho lub putty lub adhesion, yooj, dej kuj, workability thiab durability. Los ntawm kev ua raws li cov nplaum nplaum thiab txhim kho ntau yam khoom ntawm phab ntsa putty, RDP ua kom muaj cov txheej txheem ua haujlwm siab uas muab kev sib tw, txawm tias lub hauv paus rau kev pleev xim thiab kho kom zoo nkauj sab hauv thiab sab nrauv phab ntsa. Kev nkag siab txog lub luag haujlwm ntawm RDP hauv kev tsim cov phab ntsa putty yog qhov tseem ceeb kom tau txais txiaj ntsig zoo tshaj plaws hauv kev tsim kho thiab kho cov haujlwm.
