Redispersible Polymer Hmoov

Drymix Mortar Additive-RDP

Taw qhia

Drymix mortar yog ib qho tseem ceeb hauv kev tsim kho niaj hnub no, muab kev ua haujlwm zoo, sib xws, thiab ua haujlwm ntev hauv masonry, plastering, tiling, thiab lwm yam kev siv. Ntawm ntau yam additives siv los txhim kho nws cov kev ua tau zoo,Redispersible Polymer Hmoov(RDP)plays lub luag haujlwm tseem ceeb hauv kev txhim kho adhesion, yoog raws, tuav dej, thiab cov khoom siv kho tshuab.

Dab tsi yog Redispersible Polymer Powder (RDP)?

Redispersible Polymer Powder yog ib qho dawb-ntws, tshuaj tsuag-qhuav hmoov tau los ntawm polymer emulsions. Cov hmoov no redisperse nyob rau hauv dej kom rov tsim ib tug polymer emulsion, muab kev txhim kho zog rau cov tshuaj khib sib tov.

Kev sib xyaw ntawm RDP

RPPs feem ntau muaj xws li:

1. Base Polymer:Vinyl acetate ethylene (VAE), styrene-butadiene (SB), los yog acrylic-based polymers.
2. Kev Tiv Thaiv Colloids:Polyvinyl cawv (PVA) los yog lwm yam stabilizers tiv thaiv coagulation ntxov ntxov.
3. Anti-Caking Agents:Mineral fillers zoo li silica los yog calcium carbonate txhim kho flowability thiab cia ruaj khov.
4. Additives:Txhawm rau txhim kho hydrophobicity, yoog raws, lossis teeb tsa lub sijhawm.

Kev ua haujlwm ntawm RDP hauv Drymix Mortar

Kev suav nrog RDP hauv cov txheej txheem drymix mortar muaj ntau yam zoo:

1. Enhanced Adhesion:RDP nce kev sib raug zoo ntawm cov tshuaj khib thiab cov substrates xws li pob zeb, cib, vuas, thiab rwb thaiv tsev boards.
2. Txhim kho Flexibility & Deformation Resistance:Qhov tseem ceeb hauv cov ntawv thov uas yuav tsum tau ua kom tawg thiab ua kom yooj yim, xws li sab nraud thermal rwb thaiv tsev sib xyaw tshuab (ETICS).
3. Kev tuav dej & kev ua haujlwm:Ua kom muaj dej kom zoo ntawm cov cement, txo cov dej poob thiab txhim kho lub sijhawm qhib rau daim ntawv thov.
4. Mechanical Strength & Durability:Reinforces cohesion, abrasion tsis kam, thiab kev cuam tshuam tsis kam, ua kom lub cev ruaj khov mus ntev.
5. Dej Resistance & Hydrophobicity:Cov RDPs tshwj xeeb tuaj yeem faib cov dej-repelling zog, muaj txiaj ntsig zoo hauv kev siv dej tsis zoo.
6. Freeze-Thaw Resistance:Pab tswj kev ua tau zoo nyob rau hauv cov huab cua sib txawv.
7. Txhim kho Rheology & Application Properties:Txhim khu flowability thiab yooj yim ntawm kev siv nyob rau hauv ob qho tib si phau ntawv thiab tshuab siv.

Hom RDP Raws li Polymer Composition

1. Vinyl Acetate-Ethylene (VAE):
   • Feem ntau siv rau hauv cov pobzeb nplaum, plastering mortars, thiab tus kheej-leveling compounds.
   • Muab kev sib npaug yooj yooj yim thiab adhesion.
2. Styrene-Butadiene (SB):
   • Muab cov dej tsis kam thiab yoog raws.
   • Haum rau waterproofing mortars thiab kho mortars.
3. Acrylic-raws li RPP:
   • High adhesion zog thiab UV tsis kam.
   • Nyiam nyob rau hauv cov hniav txheej thiab daim ntaub ntawv waterproofing.

Kev siv ntawm RDP hauv Drymix Mortar

1. Pobzeb Adhesives & Pobzeb Grouts:Txhim kho adhesion thiab yooj rau kev sib txuas zoo ntawm cov vuas thiab substrates.
2. Plasters & Renders:Txhim kho cohesion, workability, thiab crack resistance.
3. Self-Leveling Compounds (SLCs):Muab smooth leveling nrog zoo flowability thiab lub zog.
4. ETICS (External Thermal Insulation Composite Systems):Pab txhawb rau kev cuam tshuam thiab yoog raws.
5. Waterproof mortars:Txhim kho cov khoom siv hydrophobic, ua kom muaj kev tiv thaiv tiv thaiv kev ya raws.
6. Kho Mortars:Txhim kho adhesion, mechanical zog, thiab durability rau kev kho pob zeb.
7. Masonry Mortars:Txhim khu kev ua hauj lwm thiab kev sib khi lub zog hauv kev siv cib.
8. Gypsum-Based Compounds:Siv hauv cov phab ntsa ntub dej thiab cov gypsum plasters kom zoo dua adhesion thiab yooj.

Cov xwm txheej cuam tshuam rau RDP Kev Ua Haujlwm

1. Particle Loj & Distribution:Muaj feem xyuam rau dispersibility thiab tag nrho kev ua tau zoo nyob rau hauv mortar.
2. Polymer muaj pes tsawg leeg:Txiav txim siab yooj, adhesion, thiab hydrophobicity.
3. Noj ntau npaum:Feem ntau yog nyob nruab nrab ntawm 1-10% ntawm qhuav mix hnyav nyob ntawm daim ntawv thov.
4. Compatibility nrog lwm yam additives:Yuav tsum tau kuaj nrog cov cement, fillers, thiab lwm yam tshuaj additives kom tsis txhob muaj kev phiv tshuaj.

Qhov zoo ntawm Kev Siv RDP hauv Drymix Mortar

1. Nce Txee Lub neej & Cia ruaj khovvim nws cov hmoov qhuav qhuav.
2. Yooj yim ntawm kev tuav & kev thauj mus lospiv rau kua latex additives.
3. Kev Ua Tau Zoo & Kev Ua Haujlwm Zoolos ntawm kev zam kev sib xyaw ntawm qhov chaw sib txawv.
4. Sustainable & Eco-phooj ywgraws li nws txo cov khoom siv pov tseg thiab siv cov khoom siv.

Redispersible Polymer Hmoovyog ib qho tseem ceeb additive nyob rau hauv drymix mortar, pab txhim kho txhua yam khoom, adhesion, yooj, thiab durability. Nws cov ntawv thov ntau yam ua rau nws tseem ceeb hauv kev tsim kho niaj hnub no, ua kom cov qauv zoo thiab siv tau ntev. Nkag siab txog hom RDP txoj cai, ntau npaum li cas, thiab kev tsim qauv yog qhov tseem ceeb rau kev ua tiav qhov kev ua tau zoo ntawm mortar.
