Matope a eps granilar outitsani matope ndi zopepuka zopepuka ndi zopepuka zokutira zophatikizika ndi zonunkhira zam'madzi, zomangirira, ma addictures, zowonjezera, zowonjezera m'maganizo munjira inayake. Pakati pa magetsi a EPS granilal zisudzo pakadali pano ndikugwiritsa ntchito, zitha kubwezeretsedwanso kufalitsa ufa wa lated Kugwirira ntchito kwa eps tinthu osonyeza matope a khoma lakunja kumachokera kumphepete mwa polymer, ndipo kapangidwe kake kamakhala vinyl acetate / ethyne Coolymer. Ufa wokwezedwa wa latx ukhoza kupezeka ndi utsi wowuma mtundu wa polima. Chifukwa cha kukonzekera mwatsopano, mayendedwe osavuta osungirako obwezeretsanso aposachedwa pomanga, mawonekedwe apadera omasuka chifukwa cha kukonzekera mwa njira yake, mayendedwe osavuta komanso osungira mosavuta. Magwiridwe a ESS times otsimikiza zimatengera mtundu ndi kuchuluka kwa polymer omwe amagwiritsidwa ntchito. Ethylene-vinyl acetate matrax ufa (Eva) yokhala ndi Ethylene Yokwera ndi TG yotsika (kutentha kwagalasi) kumakhala ndi magwiridwe antchito abwino malinga ndi mphamvu yayikulu, gwiritsani ntchito madzi.
Kutsindika kwa ufa wa matope pa matope ndi chifukwa chakuti matope a latx ndi polar polar. Pamene matex ufa umasakanikirana ndi ma cell eps, gawo lomwe silikugwiritsa ntchito mu unyolo waukulu wa polymer lidzasokonekera ndi polar sopo. Magulu a Polar mu polymer amadzimangirira kunja kwa ma eps tinthu tambiri, kotero kuti ma eps tinthu a epsphobicity to hydrophicity. Chifukwa cha kusintha kwa nkhope ya eps tinthu tating'onoting'ono tating'ono, zimathetsa vuto lomwe tinthu tambiri tambiri zimadziwika ndi madzi. Kuyandama, vuto la matope ambiri. Pakadali pano, simenti ikawonjezeredwa ndikusakanikirana, mabungwe a polarbed pamwamba pa eps tinthu tating'onoting'ono timacheza ndi simenti ndi kuphatikiza mosavuta, kotero kuti kugwirira ntchito kwa matope kumachitika bwino kwambiri. Izi zikuwonetsedwa pakuti tinthu tambiri tinthu tating'onoting'ono tambiri timenti, ndipo kukakamiza pakati pa awiriwo kumayendetsedwa bwino.
Emulsion ndikubwezeretsedwanso ufa wa mateyo amatha kupanga nyonga yayikulu ndikulimbana ndi zinthu zosiyanasiyana pambuyo popanga matope, simenti ndi polymer imagwirizanitsa mwamphamvu ku mapangidwe a matope. Poona microstruction wa simenti yopanga simenti yopanga, imakhulupirira kuti kuwonjezera kwa ufa wobwezeredwa ndikukhala gawo la khoma la bowo, ndikupanga mawonekedwe ake onse kudzera mu mphamvu yamkati, zomwe zimapangitsa mphamvu yamkati yamatope. Mphamvu za Polimani, potithandizanso kuti muwonjezere kulephera kwa matope ndikuwonjezera zovuta zonse. Kuti muphunzire magwiridwe antchito anthawi yayitali mu matope, idawonedwa ndi Sem kuti patatha zaka 10, micrestructuctuctuctuctuctuct ya matopeyo sinasinthe, kubisala mokhazikika, kuthekera kovuta komanso madzi abwino. Mapangidwe a Mphamvu ya Tile Amile adaphunzitsidwa pa ufa wokwezeka, ndipo adapezeka kuti polymer adautsidwa mufilimu, kanema wa polymer adapanga kulumikizana pakati pa matope ndi matayala mbali imodzi, ndipo Dzanja linalo, polymer mu matope limawonjezera mpweya wa matope ndikukhudza mapangidwe ake, ndipo pambuyo pake polymer imathandiziranso pazinthu zamagetsi komanso shrinkage Ma binder, zonsezi zithandiza kukonza mphamvu.
Kuwonjezera ufa wokwezeka wa matope ku matope amatha kusintha kwambiri mphamvu yogwirizira ndi zinthu zina, chifukwa gawo lamadzimalo la simenti ndi ma capullaries amalowa mu ma pores ndi capillaries . Kanema wamkati amapangidwa ndikukhomedwa molimba pansi pa gawo lapansi, ndikuwonetsetsa kuti ali ndi thanzi labwino pakati pa chinthu chokhazikika komanso gawo lapansi
