Lub luag haujlwm ntawm Redispersible Polymer Powder (RDP) hauv Cement Mortar

Hauv kev tsim kho niaj hnub no, kev nrhiav kev ua haujlwm ruaj khov, hloov tau yooj yim, thiab kev ruaj ntseg tau tsav cov khoom siv siab heev.Redispersible Polymer Powder (RDP)sawv ntawm lub forefront ntawm no evolution, revolutionizing tsoos cement-based systems. Raws li cov khoom tseem ceeb hauv kev ua haujlwm siab mortars,RDPtxhim khu adhesion, waterproofing, thiab mechanical zog, ua rau nws indispensable rau architects, neeg cog lus, thiab manufacturers thoob ntiaj teb.

Kev nkag siabRedispersiblePolymerHmoov (RDP)

Redispersible polymer hmoov yog ib qho hloov pauv polymer hmoov tau los ntawm cov tshuaj tsuag kom qhuav binary los yog ternary copolymer ntawm vinyl acetate thiab versatate vinyl ester los yog ethylene los yog acrylate, thiab nws muaj zoo redispersibility. Thaum sib xyaw nrog dej, nws rov ua dua rau hauv qhov ruaj khov emulsion, tsim cov yeeb yaj kiab tiv thaiv uas khi cov aggregates thiab cov cement hais.

Cov txheej txheem no txhim kho cov mortar qhov kev ua tau zoo los ntawm kev sib txuas ntawm cov cement rigidity thiab niaj hnub kev tsim kho qhov kev thov rau resilience.

Core ZoontawmRedispersible Polymer Hmoov (RDP)

• · Txhim kho Adhesion: RDP tsim kom muaj kev sib raug zoo ntawm mortar thiab substrates zoo li cov vuas, cib, lossis pob zeb, txo cov kev pheej hmoo ntawm hollowing thiab delamination.
• · Flexibility & Crack Resistance: Los ntawm kev tsim cov yeeb yaj kiab elastic, RDP txo qhov tawg los ntawm thermal expansion lossis substrate txav, ncua lub mortar lifespan.
• · Kev ua haujlwm: RDP txhim kho cov mortar qhov sib xws, ua kom yooj yim rau kev thov thiab ua kom muaj kev sib haum xeeb.
• · Durability: Cov yeeb yaj kiab polymer txhim khu kev tiv thaiv kev puas tsuaj, tshuaj lom neeg, thiab khov-thaw cycles, zoo tagnrho rau ib puag ncig hnyav.

Vim li cas Ntxiv Redispersible Polymer Powder (RDP) rau hauv Cement Mortar?

Thaum cov cement muab lub zog compressive, nws tsis muaj tensile yooj thiab dej tsis kam.JINJI CHEMICAL covRDPhais txog cov kev txwv no los ntawm:

• √Bond Strength: Ua tiav mus txog2.0 MPa nplaum lub zog, zoo tagnrho rau pobzeb adhesives thiab sab nrauv rwb thaiv tsev.
• √Crack Resistance: Txo shrinkage tawg los ntawm40% -60%piv rau unmodified mortar.
• √Kev tuav dej: Ua kom pom dej kom zoo, tseem ceeb rau cov txaj txaj txaj txaj txaj muag.
• √Flexural zog: Txhim kho yooj los ntawm15% -25%, tiv thaiv delamination nyob rau hauv ib puag ncig dynamic.
• √Kev sib koom tes: Txhim kho sag kuj rau ntsug daim ntaub ntawv xws li plastering.

Txawm li cas los xij, raws li qhov sib txawv ntawm cov mortar, nrog rau qhov sib ntxiv ntawm cov hloov pauv hloov pauv polymer hmoov kuj tseem cuam tshuam rau daim ntawv thov kev ua haujlwm ntawm mortar:

Tus nqi ntxiv ntawm redispersible polymer hmoov yog Tus nqi ntxiv ntawm redispersible polymer hmoov yog 1% -2%, uas txhim kho lub zog, dej tsis kam thiab yoog raws ntawm mortar;Tus nqi ntxiv ntawm redispersible polymer hmoov yog 2% -5%, uas ua rau reticulation polymer zaj duab xis nyob rau hauv mortar, thiab pom tseeb txhim kho lub zog thiab saj zawg zog ntawm mortar nyob rau hauv txawv kev nyab xeeb thiab interfaces.
Raws li txoj cai, lub iav hloov pauv kub ntawm cov hmoov hauv qab 5 ℃ ntawm cov khoom nws tus kheej yog hloov tau yooj yim, feem ntau yog siv rau sab nrauv rwb thaiv tsev mortar, thaum lub iav hloov kub ntawm cov hmoov saum toj no 10 ℃ yog tsuas yog siv rau hauv cov nplaum thiab nws tus kheej-leveling mortar.
