Kubwezeretsedwanso latx ufa ndi ena opanga zipatso (monga simenti, gypsim, encrophyl hydrobyprose ether, etc.) posakaniza matope osakanikirana. Matope owuma-osakaniza atawonjezeredwa kumadzi ndikusunthidwa, tinthu tating'onoting'ono tofana ndi matelex tidzakhala omwazika m'madzi pansi pa zochita za hydrophilic corloid ndi kukameta ubweya. Nthawi yofunikira kuti ikhale yokwezedwa mosavuta kuti ithe kufalitsa ndi yochepa kwambiri, ndipo malo obwezeretsanso nthawi iyi ndi gawo lofunikira kuti ayang'anire mtundu wake. Kumayambiriro koyambirira, ufa wa latedx wayamba kale kukhudza rheology ndi kugwirira ntchito matope.
Chifukwa cha mawonekedwe ndi mawonekedwe a ufa wa latedx iliyonse, izi zimasiyananso, ena amakhala ndi mphamvu yowonjezera, ndipo ena amakhala ndi chithunzi chowonjezera cha thixotropy. Njira yodzitetezera imachokera mbali zambiri, kuphatikizapo kutenthedwa kwa madzi a latex pa kupezeka kwa madzi a latex mutabala, mphamvu yoteteza simenti, komanso malamba amadzi. Zochita zimaphatikizapo kuchuluka kwa mpweya mu matope ndi kugawa kwa thovu la mpweya, komanso chizolowezi chowonjezera ndi zowonjezera zina ndi zina zowonjezera. Chifukwa chake, kusankhidwa kwachikhalidwe ndi kutumizidwanso kwaufa wobwezeretsedwa ndi njira yofunika kwambiri yokhudzira malonda. Malingaliro odziwika bwino ndikuti ufa wokwezeka umawonjezera mpweya wa matope, pomwepo potero umapangitsa kuti kuphatikizika kwa matope amathandizira kukonza matope omanga, ndipo potengera kugwiritsidwa ntchito kwa matope. Pambuyo pake, matongu onyowa omwe ali ndi mwayi wa latex ufa umagwiritsidwa ntchito pa ntchito. Ndi kuchepetsa madzi pamiyeso itatu - kuyamwa kwa maziko osanjikiza, kugwiritsidwa ntchito kwa madzi a simenti, ndipo masinthidwe a pansi pang'onopang'ono amayandikirana wina ndi mnzake, ndipo pamapeto pake khalani filimu yopitilira muyeso. Njirayi imachitika makamaka pamatope a matope ndi pamwamba.
Ziyenera kutsimikiziridwa kuti kuti izi zitheke, ndiye kuti, pamene kanema wa polymer akumananso ndi madzi, sadzabalalika kachiwiri, ndipo colloid yotetezedwa ya atchlex iyenera kulekanitsidwa ndi dongosolo la filimu ya polymer. Uwu si vuto mu matope a alkaline a Alkaline CETRAR, chifukwa lidzawonongedwa ndi alkali omwe apangidwa ndi zida za Quartz mikhalidwe, komanso motalika mathithi nthawi yayitali. M'magulu omwe sakhala alkaline, monga gypsum systems kapena machitidwe omwe ali ndi mafakitale, chifukwa cha zotetezedwa komaliza.
Ndi mapangidwe a filimu yomaliza ya Polymer, makina opangira mphamvu a aborican ndi otchuka amapangidwa m'matope obisika, ndiye kuti, utoto wa hydralic umapanga filimu pakati pa kusiyana kwa kusiyana ndi mawonekedwe okhazikika. Kulumikizana kosinthika. Kulumikizana kwamtunduwu kumatha kuganiziridwa kuti kulumikizidwa ndi mafupa okhwima ndi akasupe ang'onoang'ono. Popeza kulimba kwa mphamvu ya polimatu chopangidwa ndi ufa wa latex kumachitika nthawi zambiri kumakhala kovuta kwambiri kuposa za mitundu ya Hydraulic, ndiye kuti, Coutheon ingatheke. Popeza kusinthasintha ndi kusinthika kwa polymer ndipamwamba kwambiri kuposa simenti, kuwonongeka kwa matope, potengera kufalikira kwa matope.
