Kugwiritsa Ntchito Ether Wowuma mu Zopangira Simenti

Starch ether ndi mtundu wa Hydroxypropyl starch ether yomwe imagwiritsidwa ntchito kwambiri ngati chowonjezera muzinthu zopangidwa ndi simenti monga matope, konkire, ndi ma grouts. Ntchito yayikulu ya wowuma ether muzinthuzi ndikuwongolera magwiridwe antchito awo, kusunga madzi, komanso kumamatira. Kuyika kwa starch ether muzinthu za simenti kungafotokozedwe motere:

1. Kupititsa patsogolo ntchito: Wowuma ether amatha kusintha magwiridwe antchito a zinthu zopangidwa ndi simenti pochepetsa kukhuthala kwake. Izi zimatheka ndi adsorption wa wowuma etere mamolekyulu pamwamba pa particles simenti, amene amachepetsa awo amalipiritsa electrostatic ndi kumawonjezera kuyenda. Izi zimathandiza kuti particles za simenti ziziyenda momasuka, zomwe zimapangitsa kuti pakhale madzi ambiri komanso osavuta kugwira ntchito ndi osakaniza.
2. Kusungirako madzi: Wowuma ether amatha kukonza kusungirako madzi kwa zinthu zopangidwa ndi simenti popanga filimu yoteteza kuzungulira tinthu tating'ono ta simenti. Firimuyi imalepheretsa madzi omwe ali mumsanganizowo kuti asatuluke msanga, zomwe zimapangitsa kuti simenti ikhale yogwira ntchito kwa nthawi yaitali. Izi ndizofunikira makamaka pakatentha komanso kowuma, komwe madzi amatuluka kuchokera ku simenti yopangidwa ndi simenti.
3. Kumamatira: Wowuma ether amatha kupititsa patsogolo kumamatira kwa zinthu zopangidwa ndi simenti ku gawo lapansi powonjezera mphamvu zawo. Izi zimatheka ndi mapangidwe zomangira haidrojeni pakati pa wowuma etere mamolekyulu ndi gawo lapansi pamwamba, amene kumawonjezera interfacial adhesion mphamvu. Izi zimakulitsa mphamvu yomangirira pakati pa chinthu chopangidwa ndi simenti ndi gawo lapansi, kuchepetsa chiopsezo chachitetezo kapena kulephera.
4. Mng'alu kukana: Wowuma ether amathanso kukulitsa kukana kwa ming'alu ya zinthu zopangidwa ndi simenti powonjezera mphamvu zawo zolimba. Izi zimatheka ndi mapangidwe atatu-dimensional maukonde wa wowuma ether mamolekyu mu osakaniza, amene amachita monga kulimbikitsa ndi kuthandiza kugawira kumavuta kwambiri mofanana. Izi zitha kupititsa patsogolo kukhazikika komanso moyo wautali wazinthu zopangidwa ndi simenti.

Mwachidule, kugwiritsa ntchito ether wowuma muzinthu zopangidwa ndi simenti kungawongolere magwiridwe antchito awo, kusunga madzi, kumamatira, komanso kukana ming'alu. Wowuma ether amakwaniritsa izi mwa kuchepetsa kukhuthala kwa osakaniza, kupanga filimu yoteteza kuzungulira tinthu ta simenti, kukulitsa mphamvu ya osakaniza, komanso kukulitsa mphamvu yamphamvu ya mankhwalawa. Kugwiritsiridwa ntchito kwa starch ether muzinthu zopangidwa ndi simenti kungathe kupititsa patsogolo ntchito yonse ndi kukhazikika kwa osakaniza, zomwe zimapangitsa kuti ntchito yomanga ikhale yogwira mtima komanso yogwira mtima.
