Dab tsi ntawm mortar tuaj yeem hloov pauv tau polymer hmoov txhim kho?

Redispersible polymer hmoov (RPP) feem ntau yog siv rau hauv mortar formulations los txhim kho ntau yam khoom thiab kev ua tau zoo. Nov yog qee yam ntawm cov khoom tseem ceeb ntawm mortar uas RPP tuaj yeem txhim kho:

1. Adhesion: RPP txhim kho qhov adhesion ntawm mortar rau substrates xws li pob zeb, masonry, ntoo, thiab hlau nto. Qhov no txhim kho adhesion pab tiv thaiv delamination thiab ua kom muaj kev sib raug zoo ntawm cov tshuaj khib thiab cov substrate.
2. Flexural Strength: Kev sib xyaw RPP rau hauv mortar formulations tuaj yeem ua rau muaj zog flexural, ua rau cov mortar tiv taus kev tawg thiab deformation. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov uas lub substrate yuav muaj kev txav los yog thermal expansion thiab contraction.
3. Kev tuav dej: RPP txhim kho cov dej tuav cov khoom ntawm cov tshuaj khib nyiab, tso cai rau lub sijhawm ntev ntawm cov ntaub ntawv cementitious. Qhov no ua rau muaj kev ua haujlwm zoo dua, qhib lub sijhawm qhib, thiab txhim kho adhesion, tshwj xeeb tshaj yog thaum kub lossis cua txias.
4. Kev ua haujlwm tau zoo: RPP txhim kho kev ua haujlwm tau zoo thiab sib xws ntawm mortar, ua kom yooj yim rau kev sib xyaw, thov, thiab sib kis. Qhov no tso cai rau kom muaj kev tiv thaiv zoo dua thiab daim ntawv thov sib xws, txo qhov kev pheej hmoo ntawm cov voids lossis qhov khoob hauv cov mortar tiav.
5. Txo Shrinkage thiab Cracking: Los ntawm kev txhim kho adhesion, yooj, thiab tuav dej, RPPs pab txo qis shrinkage thiab cracking nyob rau hauv mortar. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov uas shrinkage tawg tuaj yeem cuam tshuam qhov kev ncaj ncees thiab kav ntev ntawm cov tshuaj khib.
6. Durability: Kev siv RPP tuaj yeem txhim kho qhov ua tau zoo ntawm cov tshuaj khib nyiab los ntawm kev ua kom nws tiv taus huab cua, tshuaj tua kab mob, thiab puas. Qhov no ua rau cov mortar ntev ntev uas tswj nws cov qauv kev ncaj ncees nyob rau lub sijhawm.
7. Thermal and Moisture Resistance: RPP tuaj yeem txhim kho cov thermal thiab noo noo tsis kam ntawm mortar, ua rau nws haum rau siv nyob rau hauv ib tug ntau yam ntawm tej yam kev mob, xws li freeze-thaw mus, high humidity, thiab kub hloov.
8. Bond Strength: RPP pab txhawb rau kev sib raug zoo ntawm cov tshuaj khib nyiab, ua kom muaj zog adhesion ntawm ib tus neeg mortar txheej thiab nruab nrab ntawm cov mortar thiab substrate. Qhov no yog qhov tseem ceeb rau kev ua tiav cov kev sib dhos txhim khu kev qha thiab siv tau ntev.

Kev koom ua ke ntawm redispersible polymer hmoov nyob rau hauv mortar formulations muaj ntau yam kev pab cuam, nrog rau kev txhim kho adhesion, flexural zog, dej tuav, workability, durability, thiab kuj rau shrinkage, cracking, thiab ib puag ncig yam. Cov kev txhim kho no ua rau RPP-hloov mortars haum rau ntau hom kev tsim kho, nrog rau kev teeb tsa pobzeb, stucco thiab plastering, kho thiab kho dua tshiab, thiab waterproofing.
