HPMC kwa zomatira matailosi

Ntchito ya HPMC (hydroxypropyl methylcellulose) mu zomatira matailosi makamaka imaphatikizapo mfundo izi:

Kusungirako madzi: HPMC imagwira ntchito yofunika kwambiri popititsa patsogolo kusungidwa kwa madzi kwa zomatira matailosi. Zimapanga filimu pamwamba pa tinthu tating'onoting'ono, kuteteza kutsekemera kwa madzi mofulumira komanso kusunga madzi osakanikirana kuti azitha kusungunuka bwino.

Thickener: HPMC imakhala ngati thickener, kuonjezera mamasukidwe akayendedwe a zomatira, amene bwino workability ndi kupewa matailosi kugwa kapena kutsetsereka pa unsembe.

Nthawi yotseguka yowonjezereka: Kuphatikizidwa kwa HPMC kumakulitsa nthawi yotseguka ya zomatira, kupatsa oyika nthawi yochulukirapo kuti akhazikitse ndikusintha matailosi zomatira zisanalimba.

Kulimbitsa mphamvu yomangira: HPMC imathandizira kulimba kwa zomatira polimbikitsa hydration yunifolomu ya tinthu ta simenti, zomwe zimapangitsa kuti pakhale mgwirizano wamphamvu pakati pa zomatira ndi gawo lapansi.

Kusinthasintha: HPMC imapereka zomatira ku matailosi kusinthasintha, kuchepetsa kuthekera kwa kusweka chifukwa chakuyenda kwa gawo lapansi kapena kusinthasintha kwa kutentha.

Kugwirizana kwa zomatira: HPMC imakulitsa mgwirizano wa zomatira, kuonetsetsa kuti pali mgwirizano wamphamvu pakati pa matailosi ndi gawo lapansi.

Anti-sagging: Makhalidwe akukhuthala a HPMC amathandiza kuti matailosi asagwere pamalo oyimirira.

Kupititsa patsogolo ntchito yomanga: HPMC imafulumizitsa nthawi yomanga zinthu monga simenti ndi gypsum, kuchepetsa ndalama zogwirira ntchito, potero kumapangitsa kuti zomangamanga zikhale bwino.

Kumamatira kowonjezera: HPMC imathandizira kumamatira kwa simenti- ndi zinthu zopangidwa ndi gypsum ku magawo osiyanasiyana, kuphatikiza konkriti, zomangira, ndi matailosi, potero kuchepetsa chiopsezo cholephera ndikupewa zovuta zomwe zingakonze pambuyo pake.

Kuwongolera bwino kwa ma rheology: HPMC imapangitsa kusakaniza kukhala kwamadzimadzi kwambiri komanso kudzipanga tokha popanda kukhudza kukhazikika kwake.

Kukhazikika kokhazikika: HPMC imachepetsa kuchuluka kwa madzi osakaniza konkire, potero kuchepetsa kugwiritsa ntchito simenti komanso kuwononga chilengedwe.

HPMC imagwira ntchito zosiyanasiyana zomatira matailosi, kuyambira kukonza kusungika kwa madzi ndi mphamvu zomangira zomangira mpaka kukonza zomanga ndi kusinthasintha, zonse zomwe zili zofunika kwambiri pakuwonetsetsa kuti zomatira za matailosi zikuyenda bwino komanso mtundu wa zomangamanga.
