RDP rau kho mortar

RedispersiblePolymer hmoov RDPlos ntawm qhov kub thiab txias, kev kub siab, tshuaj tsuag kom qhuav thiab ntau yam kev ua kom zoo dua cov hmoov ua ke, tuaj yeem ua rau cov mortar txhim kho lub peev xwm sib txuas thiab nws lub zog tensile, poob tsis kam, dej tuav thiab thickening kev ua haujlwm, dej tsis kam, khov- thaw kuj, kub aging kev ua tau zoo, cov khoom xyaw yooj yim, siv tau yooj yim. Kom tawg musPolymer hmoov RDPthiab cov cement muaj fusion zoo heev, pob txha pob txha tuaj yeem yaj tag nrho hauv cov cement mortar paste, lub zog ntawm cov cement, kho tsis txo ob qho tib si khaws cov nplaum nplaum, cov cuab yeej ua yeeb yaj kiab thiab yooj yim, tab sis kuj muaj kev tiv thaiv zoo corrosion, ruaj khov thiab kev sib koom ua ke. thiab tawg tsis kam, qhuav hind, tuaj yeem tiv thaiv kev yaig ntawm acidic huab cua ntawm phab ntsa, Nws tsis yooj yim rau powdery thiab deliquescent tom qab raug ya raws. Nws tuaj yeem txhim kho kev ua haujlwm ntawm mortar, txhim kho lub zog ntawm mortar, txhim kho kev sib raug zoo ntawm mortar thiab ntau yam substrates, txhim kho qhov yooj thiab hloov pauv kab ntawm mortar, compressive zog, flexural zog, hnav tsis kam, toughness, adhesion thiab dej tuav peev xwm, kev tsim kho. Ntxiv rau,Polymer hmoov RDPnrog hydrophobicity tuaj yeem ua rau mortar muaj dej tsis kam.

RedispersiblePolymer hmoov RDPfeem ntau yog sivin

1, Pobzebadhesive: ceramic pobzeb nplaum, lub tsev thiab rwb thaiv tsev board nplaum;

2, phab ntsa mortar: sab nrauv rwb thaiv tsev mortar, hniav mortar;

3, pem teb mortar: self-leveling mortar, kho mortar, waterproof mortar, qhuav hmoov interface tus neeg sawv cev;

4, hmoov txheej: sab hauv thiab sab nrauv phab ntsa thiab cov hmoov txhuam hniav,Polymer hmoov RDPhloov cov txiv qaub-cement plaster thiab xim;

5, cov khoom sib koom ua ke: ceramic pobzeb sib koom tus neeg sawv cev, sib koom ua ke mortar.

Qhov zoo ntawm redispersiblePolymer hmoov RDP

1, tsis tas yuav khaws cia thiab thauj nrog dej, txo nqi tsheb thauj mus los;

2, lub sijhawm cia ntev, tiv thaiv khov, yooj yim khaws cia;

3, me me, lub teeb yuag, yooj yim siv;

4, tuaj yeem sib xyaw nrog hydrocoagulable binder, nrog cov khoom siv hluavtaws hloov ua ntej, siv tsuas yog ntxiv dej tuaj yeem, uas tsis tsuas yog zam kev sib xyaw ua haujlwm ntawm qhov chaw, tab sis kuj txhim kho kev nyab xeeb ntawm cov khoom tuav.

Kev ua haujlwm ntawm redispersiblePolymer hmoov RDP

Nyob rau hauv lub mortar yog nyob rau hauv thiaj li yuav ua rau cov tsoos cement mortar tsis muaj zog xws li brittleness, siab elastic modulus ntawm kev txhim kho, fu nyob rau hauv cement mortar daim ntawv cog lus lub zog, zoo saj zawg zog thiab tensile kuj thiab ncua lub tawg ntawm cement mortar, vim hais tias thiab mortar daim ntawv interpenetrating polymer network qauv, lub pore tsim nyob rau hauv lub nruam polymer daim nyias nyias, ntxiv dag zog rau daim ntawv cog lus ntawm aggregate, Blocked ib feem ntawm lub pores nyob rau hauv lub mortar, yog li ntawd lub hardening ntawm modified mortar dua li cement mortar kev ua tau zoo muaj kev txhim kho zoo.

1, redispersiblePolymer hmoov RDPdisperses mus rau hauv ib zaj duab xis thiab plays lub luag hauj lwm txhim kho raws li ib tug thib ob nplaum;

2, kev tiv thaiv colloid yog absorbed los ntawm mortar system (zaj duab xis yuav tsis raug puas los ntawm dej, los yog "secondary dispersion");

3. Cov zaj duab xis-forming polymer resin yog faib nyob rau hauv tag nrho mortar system raws li cov khoom siv ntxiv, yog li ua kom cov cohesion ntawm mortar;

In khomortar

Txhim kho kev tsim kho kev ua haujlwm; Txhim kho kev khiav dej num; Nce thixotropy thiab sag kuj; Txhim kho kev sib raug zoo; Ntxiv sijhawm qhib; Txhim khu kev tuav dej.

Tom qab curing mortar

Txhim kho lub zog tensile; Ua kom muaj zog dabtsi yog khoov; Txo cov elastic modulus; Txhim kho deformability; Ua kom cov khoom compactness; Ua kom hnav tsis kam; Txhim kho lub zog cohesion; Txo carbonization qhov tob; Txo cov dej nqus ntawm cov khoom; Ua kom cov khoom muaj dej zoo ntxiv (ntxiv cov dej nce roj hmab hmoov)
