Matope a eps granilar outitsani matope ndi zopepuka zopepuka zokutira ndi chotupa cha itorganic, chomangira, kuphatikizika, kuphatikizika ndi kuphatikizika ndi kuwunikira mogwirizana. Mu kafukufuku wapano ndi kugwiritsa ntchito kwa ESS times zotchinga, ufa wobwezeretsedwanso umakhala ndi mphamvu kwambiri pakuchita kwa matope ndipo amakhala ndi chidwi chokwanira. Kugwirira ntchito kwa ma eps tinthu tating'onoting'ono totupa tout matenthedwe amachokera ku polymer comber, ndipo chinthu chake chimakhala cha vinyl acetate / ethyne Coolymer. Mtundu wamtunduwu wa elilme ukhoza kukhala wouma, wowuma kuti upeze ufa wokwezeka. Chifukwa cha kukonzekera kosinthika kwa matex ufa pomanga, mayendedwe osavuta ndi kusungidwa kosavuta, ufa womasuka wa oiwo wakhala chinthu chotukuka chifukwa chokonzekera bwino, mayendedwe abwino komanso kusungidwa kosavuta. Magwiridwe a ESS times otsimikiza zimatengera mtundu ndi kuchuluka kwa polymer omwe amagwiritsidwa ntchito. Ethylene-vinyl acetate matrax ufa (Eva) yokhala ndi Ethylene yokhala ndi ma ethylene (kutentha kwa galasi (kutentha kwagalasi) kumakhala ndi katundu wabwino kwambiri malinga ndi mphamvu yayikulu, kulimbikira mphamvu.
Kutha kwa ntchito ya matope osinthika pamatope ndi chifukwa chakuti polymer ufa ndi polar polar. Pamene Rdp imasakanikirana ndi ma cell eps, gawo lomwe silikusintha mu unyolo waukulu wa polymer ufa wa Adsorb ndi polar ya eps. Magulu a Polar mu polymer amadzimangirira kunja kwa ma eps tinthu tambiri, ndikupangitsa kuti tizilombo tosiyanasiyana tizilombo tokha. Chifukwa cha kusinthidwa kwa nkhope ya eps tinthu tating'onoting'ono ndi polymer, vuto lomwe limakhala ndi zovuta kukwaniritsa madzi amathetsedwa. Kuyandama, mavuto akulu othamangitsa matope. Pakadali pano, powonjezera simenti ndi kulimbikitsa, pamagulu a polarbed pamwamba pa eps tinthu tating'onoting'ono timalumikizana ndi matope ndi kuphatikiza kwambiri, zomwe zimawongolera kugwirira ntchito kwa matope. Izi zikuwonetsedwa pakuti tinthu tambiri tinthu tambiri timanyowa mosavuta ndi simenti pang'ono, ndipo mphamvu yolumikizana pakati pa awiriwa imayendetsedwa bwino.
Pambuyo pa emulsion ndikuyika ufa wa latx umapangidwa mu filimu, amatha kupanga mphamvu zapamwamba kwambiri ndikulimbana ndi zinthu zosiyanasiyana. Amagwiritsidwa ntchito ngati chingwe chachiwiri mu matope kuti athe kuphatikizapo ndi simenti ya zonunkhira, simenti ndi polymer motsatana. Sewerani nyonga yolingana ndikusintha matope. Poona microstruction ya simenti yopanga simenti, imawerengedwa kuti kuwonjezera kwa ufa wobwezeredwa mphamvu ya matope. Mphamvu ya Polimer, potero akuwonjezera kulephera kwa matope ndikuwonjezera zovuta. Kuti muphunzire kugwirira ntchito kwa nthawi yayitali mu matope ophatikizidwa ndi matope, zaka 10, micrestruction wa polymer mu matope sanasinthe, kubisalako kovuta, oyenda bwino komanso hydraphbic yabwino . Kutenga ufa waposachedwa monga chinthu chofufuzira, mphamvu yopanga mphamvu ya tile idaphunzirira, ndipo idapezeka kuti polima idauma mufilimu, kanema wa polymer adapanga kulumikizana pakati pa matope ndi matayala pa dzanja limodzi , ndipo mbali inayo, ma pointra a matope amawonjezera mpweya wa matope, akukhudza kuthyolako komanso kuwonongeka kwa mawonekedwe, ndipo pambuyo pake ma poizoni nawonso amagwiranso ntchito mokakamiza komanso shrinka simenti. Zochita zonsezi, izi zimathandizira kukulitsa mphamvu.
Kuwonjezera ufa wokwezeka wa latlex ku matope amatha kusintha kwambiri mphamvu yogwirizira ndi zinthu zina, chifukwa kuyimitsidwa kwamadzi kumalowa mu ma porerix, pomwe ufa wa latex umalowa mu ma pores ndi mu Capillary. Kanema wamkati amapangidwa ndikuwaletsa mwamphamvu padziko lapansi, motero kuonetsetsa kuti ubale wabwino pakati pa zinthu zopangidwa ndi zinthu.
