Waterproof mortar yog hais txog cov cement mortar uas muaj cov dej tsis zoo thiab impermeability tom qab hardening los ntawm kev kho cov mortar piv thiab siv cov kev tsim kho tshwj xeeb. Waterproof mortar muaj huab cua tsis zoo, ua haujlwm ntev, impermeability, compactness thiab tsis tshua muaj siab adhesion nrog rau cov dej tsis muaj zog thiab tiv thaiv corrosion. Daim ntawv thov ntawm redispersible polymer hmoov raws li lub ntsiab additive nyob rau hauv waterproof mortar tau ho txhim kho lub zuag qhia tag nrho kev ua tau zoo ntawm waterproof mortar, ua rau nws ib tug ntawm indispensable cov ntaub ntawv nyob rau hauv kev tsim kho tej yaam num.
Daim ntawv thov ntawm redisoersible hmoov nyob rau hauv waterproof mortar mas qhia nyob rau hauv cov nram qab no yam:
Waterproof thiab anti-seepage: Cov hmoov redispersible tuaj yeem sau cov pores hauv cov tshuaj khib nyiab, tsim cov txheej txheem dej tsis zoo hauv cov tshuaj khib nyiab, tiv thaiv dej nkag thiab txhim kho cov dej tsis zoo ntawm tag nrho cov mortar txheej.
Kev sib raug zoo ntawm lub zog: Redispersible polymer hmoov tuaj yeem txhim kho kev sib txuas thiab adhesion ntawm mortar thiab txheej txheej, ua rau cov txheej txheem dej tsis zoo thiab tsis tshua muaj kev poob.
Freeze-thaw kuj: redispersible polymer hmoov tuaj yeem pab txhim kho lub khov-thaw tiv thaiv ntawm mortar, ua rau nws haum rau cov huab cua sib txawv; redispersible polymer hmoov tuaj yeem txhim kho lub zog tensile ntawm mortar, ua rau cov mortar ntau ruaj. Los ntawm kev ua kom muaj kev sib koom ua ke sab hauv thiab viscosity ntawm mortar, tag nrho lub zog ntawm mortar tau txhim kho.
Kev siv yooj yim: Redispersible polymer hmoov feem ntau tuaj yeem yaj sai sai hauv dej txias thiab tuaj yeem txhim kho cov txheej txheem kev ua haujlwm ntawm cov cement mortar, uas yuav pab tswj tau cov txheej txheem kev tsim kho ntawm mortar thiab txhim kho kev tsim kho.
Cov teebmeem ntawm redispersible polymer hmoov ntawm cov dej tsis zoo mortar tshiab:
A, Txhim kho kev ua haujlwm;
B 、 Ntxiv dej tuav, txhim kho cov cement hydration;
Cov teebmeem ntawm hardening waterproof mortar:
A 、 Txo cov elastic modulus ntawm mortar thiab txhim khu nws qhov haum txuam nrog puag txheej;
B, Ua kom yooj thiab tiv thaiv kev tawg;
C 、 Txhim kho mortar ceev;
D, Hydrophobicity;
E, Ua kom adhesion.
