Kugwiritsa ntchito kufalitsa polima ufa m'matamu

Kumwatsetsa ufa wa polima ndi emu youma youma, pomwe yosakanikirana ndi madzi kapena madzi mu matope, amapanganso kubalansi kofananira monga emulsion yoyambirira. Polymer amapanga mawonekedwe a polymer network mu matope, womwe ndi wofanana ndi polimer emulsion corties ndikusintha matope. Khalidwe la kumwaza ufa ndikuti ufa uwu ukhoza kubalalitsidwa kamodzi, ndipo sudzabalalika kachiwiri pomwe matope atakhala onyowa pambuyo polimbana. Kupanga kwa polimature polima ufa wasintha kwambiri matope owuma ufa. Mu matope olumikizana chifukwa cha zokongoletsera zokongoletsera, pali zofunikira zambiri za kuchuluka kwa polymer yobwezeretsedwa polymer. Kuphatikiza kwake kumasowetsa mphamvu yothana ndi kuthekera, kusokonekera kwamphamvu, mphamvu yamphamvu komanso kulimba kwa matope, omwe angapewe. Matope shrinkage ndi kusokonekera kumathanso kuchepetsa kukula kwa mgwirizano. Polymer polymer otemex ufa akhoza kusintha zinthu zomwe zili pamwambazi chifukwa zimatha kupanga kanema wa polymer pamwamba pa matope. Pali pores pam filimuyi, ndipo malo a ma pores amadzaza ndi matope, omwe amachepetsa kupsinjika komwe kumachitika ndikuchepetsa mphamvu yakunja. Pansi pa chochitikachi chidzapanga kupumula popanda kuwonongeka. Kuphatikiza apo, matope amapangira mafupa okhwima a simenti hydration, ndipo makanema omwe amapangidwa ndi polymer amatha kusintha mafupa komanso kulimba kwa polymer atrate mphamvu ya matope.

Kupaka kopatsirana pakati pa tinthu tating'onoting'ono tofana kumathandizira zigawo za matope kuti ziziyenda pawokha. Nthawi yomweyo, imakhala ndi mphamvu pamlengalenga, ndikuyika kusiyana kwa matope, motero kumatha kukonza zomanga ndi kugwirira ntchito kwa matope. Mphamvu yovuta kwambiri ya polymer imachepetsa ndi kuchuluka kwa ufa wa mphira, mphamvu yothana ndi kuthedwa kwa kuchuluka kwa ufa wa mphira, ndipo chiwerengero chokanizira chikuwonetsa mtsogolo.

Kuyeserera kumawonetsa kuti ufa wokwezeka watchlex ungasinthe matope ndikuwonetsa bwino kusintha kwa matope. Kubwezeretsedwanso Polymer Polydel kumatha kusintha mphamvu ya madzi osinthika, makamaka mphamvu yamphamvu yosinthika matope. Ma polima ophatikizika m'mapazi am'mimba a matope owuma ndi kumathandizanso. Kuphatikiza kwa kufalitsa ufa wowuma polima kumatha kusintha kwambiri matope a matope, makamaka mukaphatikiza zinthu zosiyanasiyana, monga mataikulu a ceramic. Ndi kuwonjezeka kwa ufa wa mphira, mphamvu yodzikuza komanso mphamvu zomatira zimawonjezeredwanso.

Kuphatikizira ufa wobwezeretsa polima kumatha kukonza mwadzidzidzi kukana kwa zinthuzo, motero kumathandizira kulimba kwa zinthuzo komanso kulimbitsa thupi. Pambuyo powonjezera polymer ku matrix, mphamvu yakuliya idzayendetsedwa bwino kwambiri. Panthawi yolimbana ndi simenti, padzakhala zikopa zambiri mkati. Mafuko awa ali ndi madzi pachiyambi. Simenti ikachiritsidwa ndikuwuma, magawo awa amakhala pamiyeso. Nthawi zambiri amakondera awa ndiosavuta a simenti. gawo. Pamene ufa wokwezedwa polima umapezeka mu simenti dongosolo, ufawu umabalalika nthawi yomweyo ndikuyang'ana kwambiri malo olemera m'madzi, ndiko kuti, m'mizindayi. Madzi atawuma. Polymer amapanga filimu kuzungulira zikopazo, potero zimalimbikitsa mfundo zofooka izi. Ndiye kuti, kuwonjezera pang'ono ufa wokwezeka waposachedwa kumatha kukonza kwambiri mphamvu.
