Dab tsi yog Redispersible Polymer Powder?

Redispersible polymer hmoov(RPP) yog cov hmoov dawb-ntws, dawb tau txais los ntawm cov tshuaj tsuag-drying polymer emulsions. Nws muaj cov khoom siv polymer uas tau tawg mus rau hauv dej los tsim cov emulsion, uas tom qab ntawd qhuav rau hauv daim ntawv hmoov. RPP muaj cov khoom sib xyaw ntawm cov polymers, feem ntau yog yas acetate ethylene (VAE), vinyl acetate versatate (VAc / VeoVa), acrylics, thiab lwm yam copolymer. Cov polymers no raug xaiv raws li lawv cov khoom tshwj xeeb thiab cov phiaj xwm siv.

Nov yog qee cov yam ntxwv tseem ceeb thiab cov khoom ntawm redispersible polymer hmoov:

1. Zaj duab xis tsim: Thaum sib xyaw nrog dej, RPP cov khoom rov ua kom tawg thiab tsim cov zaj duab xis hloov tau yooj yim thaum ziab. Cov yeeb yaj kiab no muab cov nplaum nplaum, cohesion, thiab durability rau ntau yam substrates, xws li pob zeb, mortar, pobzeb nplaum, thiab coatings.
2. Adhesion: RPP txhim kho adhesion ntawm cov khoom sib txawv, nrog rau cov substrates thiab coatings, vuas thiab adhesives, thiab fibers thiab binders. Nws txhim kho lub zog ntawm daim ntawv cog lus thiab tiv thaiv delamination lossis detachment ntawm cov ntaub ntawv dhau sijhawm.
3. Flexibility: RPP imparts yooj yooj yim rau coatings, adhesives, thiab mortars, tso cai rau lawv kom haum raws li substrate txav, thermal expansion, thiab lwm yam kev ntxhov siab yam tsis muaj cracking los yog tsis ua hauj lwm. Cov cuab yeej no tseem ceeb heev rau kev tswj xyuas kev ncaj ncees ntawm cov khoom siv.
4. Dej tsis kam: RPP txhim kho cov dej tsis kam ntawm cov qauv tsim, ua rau lawv haum rau qhov chaw sab nraum zoov lossis ntub dej. Nws pab tiv thaiv kom tsis txhob ya raws nkag mus thiab tiv thaiv hauv qab substrates los ntawm kev puas tsuaj.
5. Durability: RPP txhim khu kev ruaj khov thiab huab cua ntawm cov ntaub ntawv los ntawm kev txhim kho lawv cov tiv thaiv UV hluav taws xob, tshuaj lom neeg raug, puas, thiab kev laus. Nws prolongs lub neej ntawm cov coatings, adhesives, thiab mortars, txo cov kev tu thiab cov nqi.
6. Kev ua haujlwm tau zoo: RPP txhim kho kev ua haujlwm thiab kev ua tiav ntawm cov txheej txheem los ntawm kev txhim kho ntws, theem, thiab kev sib kis. Nws ua kom muaj kev tiv thaiv ib puag ncig, kev siv du, thiab kev ua tau zoo ntawm cov khoom siv.
7. Rheology Control: RPP ua haujlwm raws li kev hloov kho rheology, cuam tshuam cov viscosity, thixotropy, thiab sag kuj ntawm formulations. Nws pab optimize daim ntawv thov zog thiab kev ua tau zoo ntawm cov txheej, nplaum, thiab mortars.
8. Compatibility: RPP yog sib xws nrog ntau yam ntawm lwm yam additives, fillers, pigments, thiab binders feem ntau siv nyob rau hauv formulations. Nws tsis cuam tshuam rau cov khoom lossis kev ua tau zoo ntawm lwm cov khoom, ua kom muaj kev ruaj ntseg thiab sib xws.

Redispersible polymer hmoov pom kev siv dav hauv kev tsim kho, suav nrog cov nplais nplaum, cement-based mortars, self-leveling compounds, waterproofing membranes, thiab kho mortars. Nws kuj tseem muaj cov ntawv thov hauv cov coatings, adhesives, sealants, textiles, thiab ntawv industries, pab txhawb rau kev ua tau zoo thiab durability ntawm ntau yam ntaub ntawv thiab cov khoom.
