Cov nyhuv ntawm kev ntxiv Redispersible polymer hmoov rau putty hmoov

Redispersible latex hmoov yog siv nyob rau hauv ib tug JS waterproof txheej, polystyrene board bonding mortar rau lub tsev rwb thaiv tsev, saj zawg zog deg tiv thaiv mortar, polystyrene particle thermal rwb thaiv tsev txheej, pobzeb nplaum, self-leveling mortar, qhuav sib tov mortar, putty, thiab lwm yam. teb ntawm kev hloov kho inorganic gelling cov ntaub ntawv tau dav siv.

 

Ntxiv redispersible latex hmoov rau putty hmoov tuaj yeem ua rau nws lub zog, muaj zog adhesion thiab txhua yam khoom, thiab pab txhim kho hardness. Nws muaj dej tsis kam, permeability, thiab zoo heev durability. Alkaline, hnav-tiv taus, thiab tuaj yeem txhim kho dej tuav, ua kom lub sijhawm qhib, thiab txhim khu kev ruaj ntseg.

 

Thaum cov hmoov redispersible latex yog nplawm tusyees nyob rau hauv cov hmoov putty thiab tov nrog dej, nws yog dispersed mus rau hauv zoo polymer hais; cement gel yog maj mam tsim los ntawm thawj hydration ntawm cement, thiab cov kua theem yog tsim los ntawm Ca (OH) 2 nyob rau hauv cov txheej txheem hydration. Saturated, thaum cov hmoov latex tsim cov ntaub ntawv polymer thiab tso rau ntawm qhov chaw ntawm cov cement gel / unhydrated cement particle sib tov; Raws li cov cement yog ntxiv hydrated, cov dej hauv capillaries txo qis, thiab cov polymer hais maj mam txwv hauv cov hlab ntsha. Adhesive / unhydrated cement particle sib tov thiab muab tub lim tsim ib txheej txheej kaw; nyob rau hauv qhov kev txiav txim ntawm hydration cov tshuaj tiv thaiv, lub hauv paus txheej nqus thiab nto evaporation, cov dej yog ntxiv txo, thiab tsim stacked txheej sib sau ua ke rau hauv ib zaj duab xis, uas khi cov hydration tshuaj tiv thaiv cov khoom nyob rau hauv ua ke lawv tsim ib tug tag nrho network qauv. Cov txheej txheem sib xyaw ua ke tsim los ntawm cov cement hydration thiab latex hmoov zaj duab xis tsim tuaj yeem txhim kho qhov kev sib tw tsis zoo ntawm putty los ntawm kev sib koom ua ke.

 

Lub putty siv los ua cov txheej txheem hloov pauv ntawm cov phab ntsa sab nraud thiab cov xim yuav tsum tsis txhob muaj zog dua li plastering mortar, txwv tsis pub tawg yuav yooj yim tshwm sim. Nyob rau hauv tag nrho cov rwb thaiv tsev system, qhov yooj ntawm lub putty yuav tsum siab tshaj ntawm cov khoom siv hauv paus. Nyob rau hauv txoj kev no, lub putty tuaj yeem hloov kho kom zoo dua rau qhov deformation ntawm lub substrate thiab tsis tuaj yeem ua rau nws tus kheej deformation nyob rau hauv qhov kev txiav txim ntawm ib puag ncig ib puag ncig, txo kev ntxhov siab, thiab txo qhov muaj peev xwm tawg thiab tev ntawm txheej.
