Dej Resistance: RDP txhim kho cov dej tsis kam ntawm cov ntaub ntawv tsim kho, tiv thaiv lawv los ntawm kev puas tsuaj xws li efflorescence, spalling, thiab khov-thaw cycles.
Durability thiab Longevity: Cov ntaub ntawv hloov kho nrog RDP nthuav qhia kev ua kom ruaj khov thiab siv tau ntev, txo qhov kev xav tau kev kho thiab tu ntau zaus.
Thermal rwb thaiv tsev: Hauv qee qhov kev siv, RDP tuaj yeem txhim kho cov thermal rwb thaiv tsev ntawm cov ntaub ntawv, pab txhawb kev siv hluav taws xob hauv tsev.
Kev siv ntawm RDP
RDP yog siv nyob rau hauv ntau yam khoom siv thiab kev siv vim nws muaj ntau yam khoom:
Mortars thiab Plasters: RDP feem ntau ntxiv rau cov cementitious mortars thiab plasters los txhim kho lawv cov kev ua haujlwm, adhesion, thiab durability. Qhov no suav nrog cov pobzeb nplaum, kho cov mortars, thiab sab nraud rendering systems.
Self-Leveling Compounds: Nyob rau hauv tus kheej-leveling pem teb tebchaw, RDP kom ib tug du, theem nto nrog txhim khu kev qha ntws thiab txo shrinkage.
Grouts: Pobzeb grouts tau txais txiaj ntsig los ntawm RDP lub peev xwm los txhim kho adhesion, saj zawg zog, thiab dej tsis kam, ua rau cov pob qij txha ntev, tsis muaj kab nrib pleb.
Adhesives: RDP yog siv nyob rau hauv ntau yam nplaum formulations rau txhim kho kev sib raug zoo zog thiab saj zawg zog, haum rau kev sib txuas cov vuas, rwb thaiv tsev panels, thiab lwm yam kev tsim kho.
Thermal Insulation Systems: Sab Nraud Thermal Insulation Composite Systems (ETICS) koom nrog RDP los txhim kho qhov adhesion thiab yooj ntawm cov txheej rwb thaiv tsev, ua kom muaj kev ua tau zoo thiab ua haujlwm ntev.
Cement-Based Paints thiab Coatings: RDP txhim kho cov khoom ntawm cov cement-raws li cov xim thiab cov txheej txheem, muab cov adhesion zoo dua, yoog raws, thiab tiv thaiv ib puag ncig.
Environmental Impact thiab Sustainability
Kev siv RDP hauv kev tsim kho muaj ntau qhov cuam tshuam ib puag ncig. Ntawm qhov zoo, RDP-hloov cov ntaub ntawv feem ntau pom tias muaj kev ruaj khov thiab siv tau ntev, txo qhov zaus ntawm kev kho thiab hloov pauv thiab yog li txuag cov peev txheej.
