Zomata za matailosi zimagwiritsidwa ntchito kwambiri pantchito zomanga zamakono. Ntchito yawo yayikulu ndikumamatira mwamphamvu matailosi pamalo omangapo kuti atsimikizire kuti matailosi sagwa kapena kusuntha. Ma cellulose ether, monga chowonjezera chofala, amagwiritsidwa ntchito kwambiri pazomatira matailosi kuti apititse patsogolo ntchito yawo.
Basic zigawo zikuluzikulu za matailosi zomatira
Zomata za matailosi nthawi zambiri zimakhala ndi simenti, mchenga, cellulose ether, guluu ufa ndi zina zowonjezera. Simenti imagwiritsidwa ntchito ngati chinthu chachikulu chomangira kuti chipereke mphamvu ya maziko; mchenga umagwiritsidwa ntchito ngati filler kuonjezera voliyumu ndi kuchepetsa kuchepa; mapadi a cellulose ether ndi ufa wa rabara amagwiritsidwa ntchito ngati zosintha kuti apititse patsogolo magwiridwe antchito komanso mawonekedwe amtundu wa zomatira.
Udindo wa cellulose ethers
Cellulose ether ndi gulu la polima lochokera ku cellulose yachilengedwe. Ntchito zake zazikulu ndi izi:
Kusungirako madzi: Ma cellulose ether amatha kupititsa patsogolo mphamvu yosungira madzi ya zomatira za matailosi a ceramic ndikuchepetsa kutuluka kwa madzi, potero kuonetsetsa kuti simenti yokwanira komanso mphamvu.
Thickening zotsatira: Ma cellulose ether amapanga zomatira kukhala zabwino thixotropy ndi kutsetsereka kukana, facilitates yomanga ndi bwino kugwirizana kwenikweni.
Limbikitsani magwiridwe antchito: Ma cellulose ether amatha kupangitsa zomatira kukhala zosalala komanso zosavuta kugwira ntchito panthawi yomanga, kupititsa patsogolo ntchito yomanga bwino komanso yabwino.
Zomwe zili mu cellulose ether pakugwira ntchito kwa zomatira za matailosi a ceramic
Kusungirako madzi: kuonjezera zomwe zili mu cellulose ether zidzathandiza kwambiri kusunga madzi kwa zomatira. Pa nthawi ya simenti ya hydration, kusungirako madzi ndikofunikira kuti mutsimikizire kuti simentiyo imakhala ndi madzi okwanira. Kukwera kwa hydration, ndipamenenso ma hydration amapangidwa ndi simenti ndikuwonjezera mphamvu ya ma bond. Chifukwa chake, kuchuluka koyenera kwa cellulose ether kumathandizira kukulitsa mphamvu ndi kulimba kwa zomatira.
Mphamvu yomangirira: Pamene zinthu za cellulose ether zikuwonjezeka, mphamvu yomangirira ya zomatira idzawonjezeka kwambiri. Ichi ndi chifukwa madzi posungira ndi thickening zotsatira za mapadi etero kulola zomatira bwino kudutsa pamwamba matailosi ceramic ndi gawo lapansi, kuwongolera mawonekedwe kugwirizana kwenikweni. Komabe, kuchuluka kwambiri kwa cellulose ether kungayambitse kukhuthala kwakukulu, kumakhudza magwiridwe antchito, ndipo kumatha kuyambitsa ming'alu ya zomatira panthawi yowumitsa, zomwe zimachepetsa mphamvu yolumikizirana.
Kugwira ntchito: Ma cellulose ether amakhudza kwambiri zomatira. Kuchuluka koyenera kwa cellulose ether kumatha kupangitsa zomatira kukhala zosavuta kuziyika ndikuzisintha panthawi yomanga, kuchepetsa kutsetsereka kwa matailosi a ceramic, ndikuwongolera ntchito yomanga. Kutsika kwambiri kwa cellulose ether kumapangitsa zomatira kukhala ndi mamasukidwe osakwanira komanso kutsetsereka mosavuta; pomwe kuchuluka kwa cellulose ether kumapangitsa zomatira kukhala zowoneka bwino komanso zovuta kupanga.
Kukana kwa Slip: Pakumanga matailosi pakhoma, kukana kuterera ndi chizindikiro chofunikira. Ma cellulose ether amatha kusintha kwambiri magwiridwe antchito a zomatira, kuwonetsetsa kuti matailosi sangatsike atayikidwa. Kafukufuku akuwonetsa kuti kuchuluka koyenera kwa cellulose ether kumatha kupititsa patsogolo luso la zomatira ku anti-slip, pomwe ether ya cellulose yochulukirapo imapangitsa kuti zomangamanga zikhale zovuta chifukwa kutsekemera kwa zomatira kumakhala kochepa kwambiri.
Zoyeserera ndi Kusanthula
Kuti muwone momwe zinthu za cellulose ether zimakhudzira magwiridwe antchito a zomatira za matailosi a ceramic, zoyeserera zotsatirazi zitha kuchitidwa:
Zida zoyesera: Gwiritsani ntchito mtundu womwewo ndi mtundu womwewo wa simenti, mchenga, ndi ufa wa rabara, ndikuwonjezera zinthu zina za cellulose ether (monga 0.1%, 0.2%, 0.3%, 0.4%, 0.5%).
Njira Zoyesera:
Mayeso osungira madzi: Yesani mphamvu yosungira madzi ya zomatira pansi pa zinthu zosiyanasiyana za cellulose ether kudzera mu njira yoyamwitsa madzi pamapepala.
Kuyesa kwamphamvu kwa ma bonding: Malinga ndi njira yapadziko lonse, mphamvu yomangira yomata ya zomatira pansi pa zinthu zosiyanasiyana zama cellulose ether imayesedwa.
Constructability test: Unikani kumasuka kwa kugwiritsa ntchito komanso kukana kwa zomatira kudzera muzomanga zenizeni.
Kusanthula deta: Kusanthula deta yoyesera, jambulani mgwirizano pakati pa zomwe zili mu cellulose ether ndi zizindikiro zogwirira ntchito monga kusungirako madzi, mphamvu zomangira, ndi kugwira ntchito kuti mupeze kuchuluka kwa cellulose ether.
Zomwe zili mu cellulose ether zimakhudza kwambiri kusungidwa kwa madzi, mphamvu zomangirira komanso kugwira ntchito kwa zomatira za matailosi a ceramic.
Kuchuluka koyenera kwa cellulose ether kumatha kusintha kwambiri magwiridwe antchito a zomatira, koma kuchuluka kwambiri kwa cellulose ether kungayambitse kukhuthala kwa zomatira, zomwe zimakhudza kugwira ntchito komanso kulumikizana.
Kupyolera mu kuyesera deta kusanthula, mulingo woyenera kwambiri mapadi etero zili osiyanasiyana akhoza anatsimikiza kukwaniritsa mulingo woyenera bwino katundu zomatira.
Kuwongolera koyenera pakuwonjezera kuchuluka kwa cellulose ether ndiye chinsinsi chothandizira zomatira za matailosi a ceramic. Kafukufuku wamtsogolo atha kuwunikiranso zotsatira za mitundu yosiyanasiyana ya ma cellulose ethers pa zomatira kuti apange zinthu zomatira zamatayilo apamwamba.
