Tus poj niam yog dab tsi yog polymer hmoov?

1. Taw qhia rau recispersible polymer hmoov (RDP)

Recispersible polymer hmoov(RDP) yog ib qho khoom siv tsim khoom tau los ntawm polymer emulsions los ntawm txau-kom qhuav. Thaum sib xyaw nrog dej, RDP kev rov ua haujlwm rau hauv cov latex, muab cov yam ntxwv zoo sib xws raws li thawj disgersion. Nws txhim kho cov nplaum, yooj yim, dej tsis kam, thiab tshaj txhua yam kav ntawm cov xis thiab gypsum-based cov ntaub ntawv.

RDP feem ntau tsim ntawm Vinyl acetate ethylene (VAE), Acrylic, lossis STyrene-butadiene copolymers. Nws cov khoom ua rau nws tseem ceeb hauv kev tsim kho tshiab rau kev tsim cov kev ua tau zooQHUAV TAWSMortars, cov nplaum nplaum, thiab cov rwb thaiv tsev sab nrauv cov tshuab (EIFS).

2. Kev Tsim Kho Cov Txheej Txheem

Kev tsim khoom ntawm RDP koom nrog cov kauj ruam hauv qab no:

1. Polymer emulsion ntau lawm: Lub hauv paus puag polymers zoo li Vae yog synthesized los ntawm emulsion polymerization.
2. Kev koom ua ke ntxiv: Kev tiv thaiv kev tiv thaiv (piv txwv li, kev haus dej cawv polyvinyl) thiab tiv thaiv cov neeg sawv cev (piv txwv li, silica) ntxiv.
3. Txau Kom Qhuav: Cov polymer emulsion yog tshuaj tsuag-qhuav los ua cov hmoov dawb-ntws.
4. Ntim: Cov hmoov tau ntim rau hauv noo noo-resistant ntim los khaws nws cov khoom.

3. Hom thiab Tshuaj lom neeg muaj pes tsawg leeg

RDP sib txawv raws li hom polymer thiab tshuaj ntxiv siv. Cov lus hauv qab no qhia txog cov hom thiab lawv cov yam ntxwv thawj zaug:

Ntxiv:

• Kev tiv thaiv colids: Polyvinyl cawv kom rov ua haujlwm dua.
• Los tiv thaiv cov neeg sawv cev: Silica tiv thaiv clumping.

4. Cov khoom thiab cov txiaj ntsig

RDP txhim kho cov ntaub ntawv tsim kho los ntawm kev muab cov khoom siv hauv qab no:

Cov Khoom Siv Neeg Kho Tshuab

• Yooj yooj: Txo kev tawg hauv cov khoom noj kom haum.
• Kua nplaum: Enhance ua raws cov chaw sib txawv.
• Lub zog tensile: Nce tsis kam rau sab nraud rog.

Cov Khoom Siv Lub Cev

• Dej ceev: Qeeb dej evaporation, txhim kho hydration.
• Kev ua haujlwm: Kev txhawb nqa cov ntawv thov kom yooj yim dua thiab ua tiav smoother.
• Yam ruaj khov: Txhim kho kom tiv thaiv huab cua sov thiab khov-thaw mus.

5. Daim ntawv thov hla kev lag luam

RDP nrhiav cov ntawv thov hauv ntau cov haujlwm, tshwj xeeb siv.

Cov Khoom Siv Siv

• Cov nplaum nplaum thiab grouts: Xyuas kom muaj zog nplaum thiab tawg.
• Kev Ntsuas Tus Kheej: Txhim kho cov khoom ntws thiab cov npoo ua tiav.
• Plasters thiab Renders: Txhim kho cov haujlwm ua haujlwm thiab kav ntev.

Rwb Thaiv Tsev Tshuab

• Eifs (sab nraud rwb thaiv tsev xov tshuab tshuab): Muab kev hloov pauv tau thiab yoog raws.

Cov kev daws teeb meem waterpingofing

• Tsho thiab cov quav mis: Txhim kho cov dej tsis kam thiab tawg-bridging.

Kho cov neeg yuav khoom Mortars

• Kev Kho Qauv Txheej Txheem: Kom tau txais kev siv tshuab lub zog kho ua haujlwm.

6. Kev ua txuj ci hauv cov ntaub ntawv tsim kho

RDP txoj kev koom tes rau cov khoom siv tsim tuaj yeem raug tshuaj xyuas los ntawm nws cov kev cuam tshuam rau cov kev ntsuas tseem ceeb.

6.1 adhesion thiab cohesion

• RDP nce lub zog ntawm lub zog ntawm cov neeg nplua nuj rau ntau hom substrates, suav nrog kev ua vaj tse, ntoo, thiab hlau.

6.2 Cov dej ua ke

• Txhim kho cov dej khaws cia kev txhawb nqa tau zoo dua Maas dej khov thiab ua haujlwm.

6.3 tawg tsis kam

• Elasticity muab los ntawm RDP tiv thaiv kev tawg vim yog cov cua sov thiab kev ntxhov siab.

7. Kev Lag Luam Zoo thiab Tsim Tawm

Kev lag luam RDP thoob ntiaj teb yog loj hlob, tsav los ntawm kev nce ntxiv rau lub zog-txuag cov khoom siv. Qhov tseem ceeb tshaj plaws xws li:

• Eco-phooj ywg cov khoom: Kev txhim kho RDP nrog cov khoom siv qis dua voc (volatile organic compound) emissions.
• Cov qauv zoo kawg nkaus: Kev nrhav hauv cov copolymer muaj pes tsawg leeg rau kev ua tau zoo.
• Kev Xav Tau Tshaj Plaws hauv Cov Kev Cim Cim: Cov txheej txheem kev loj hlob hauv Asia-Pacific yog kev xav tau.

8. Cov nyom thiab cov kev txwv

Txawm hais tias nws cov txiaj ntsig, RDP muaj qee qhov kev txwv:

• Yuag rhiab rhiab: Yuav tsum muaj kev ntim khoom noo-tiv taus.
• Tus nqi yam: High-zoo RDP yuav nce cov nqi tes haujlwm.
• Cuam tshuam ib puag ncig: Voc emissions, tab sis txo nyob rau hauv niaj hnub sib txawv.

Cov hmoov Polymer Polymer yog qhov tsis tseem ceeb hauv cov ntaub ntawv tsim kho niaj hnub, muab cov khoom ua haujlwm hloov kho los ntawm kev txhim kho adhesion, yooj yim, thiab dej tsis kam. Kev tsim kho tshiab thiab lub ntiaj teb thawb rau cov ntaub ntawv tsim kev txhim kho kom ruaj khov yuav tsum tau kev saws cov kev coj los ntawm kev saws ntawm RDP cov qauv. Raws li kev lag luam ua ntej ua tau zoo, durability, thiab ib puag ncig kev ruaj khov, RDP yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev tsim kho cov khoom siv.
