Kugwiritsa ntchito polima polder inlyder mu matope

Kuchepetsa ufa wa polmer ndi kuphika kwina kokhazikika (monga sime, staket, encrophobic hydroxyprose ether, ndi matontheki osakanizika kuti apangitse matope osakanikirana. Matope owuma-osakaniza akasakanizidwa ndi madzi, mothandizidwa ndi colloid colloid komanso makina opanga magetsi, tinthu tating'onoting'ono timene timafalikira m'madzi.

Chifukwa cha mawonekedwe osiyanasiyana ndi ufa uliwonse waposachedwa, izi ndizosiyananso, ena amathandizanso kuyenda, pomwe ena amawonjezera kukula kwa thixotropy. Njira yodzitetezera imachokera ku zinthu zambiri, kuphatikizapo mphamvu ya matebulo a latx pakubalalitsa ufa wa latex ufa, mphamvu ya colloid, ndi lamba wamadzi. Mphamvu zotsatirazi zimaphatikizanso chidwi pakuwonjezeka kwa mpweya womwe umapezeka ndi matope ndi kugawidwa kwa thovu la mpweya, komanso chizolowezi chowonjezera ndi zowonjezera zina. Chifukwa chake, kusankhidwa kwachilendo ndi kutumizidwa kwaKubwezeretsedwa Polimer Polyderndi njira yofunika kwambiri yokhudzira malonda. Zina mwa izo, malingaliro ofala kwambiri ndikuti ufa wobwezeretsedwa umawonjezera mpweya wa matope, pomwepo potero amatulutsa matope, ndipo kulumikizana ndi mafayilo otetezedwa, makamaka pamene Colloit imabalalika, kumadzi. Kuchulukitsa kwa α α kumapangitsa kuti chilengedwe cha matope a matope omanga, potero kumawongolera kugwirira ntchito kwa matope. Pambuyo pake, matope onyowa omwe ali ndi mwayi wobalalitsa wa later wa latler amagwiritsidwa ntchito kuntchito. Ndi kuchepetsa chinyezi pamitundu itatu - kuyamwa kwa maziko osanjikiza, kugwiritsidwa ntchito kwa kapangidwe kake kamene kamayambira, ndipo malo otumphukira pang'onopang'ono amayandikirana, kenako ndikuphatikiza filimu yopitilira muyeso, ndipo pamapeto pake zimakhala filimu yopitilira Njirayi imachitika makamaka pamatope a matope ndi pamwamba.

Tiyenera kutsimikizika kuti, kuti izi zitheke, ndiye kuti, kanema wa polymer sakusinthidwanso madzi, colloid yoteteza ufa ayenera kulekanitsidwa ndi pulogalamu yamakanema ya polimame. Ichi si vuto mu matope a alkaline a alkaline, chifukwa lidzakhala losoweka ndi mpweya wamafuta, ndipo nthawi yomweyo, adsorption wa zinthu za Quarz pang'onopang'ono zidzatetezedwa ndi ma hydrophilic. Colloid, kanema yemwe amakhutitsidwa m'madzi ndipo amapangidwa ndi kufalikira kwa nthawi imodzi ya ufa waposachedwa, satha kugwiritsa ntchito malo owuma, komanso m'miyeso yayitali m'madzi. M'magulu omwe sakhala alkaline, monga gypsum systems kapena machitidwe omwe ali ndi mafilimu omaliza okha, ndipo poimba akadakhalapo kwakanthawi, sizikukhudzanso kugwiritsa ntchito ufa wa polima.
