Hydroxypropyl methyl cellulose imatha kukulitsa kukana kwa matope a simenti

Hydroxypropyl methyl cellulose (hpmc)ndi polymer yosiyanasiyana yomwe nthawi zambiri imagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikizapo kupanga, mankhwala opangira mankhwala, ndi chakudya. Munthawi yomanga, makamaka pa matope a simenti, hpmc amagwira ntchito yofunika kwambiri yolimbikitsira katundu wosiyanasiyana, kuphatikizapo kubalalika kukana.

1.Kuona kuti hydroxypropyl me cellouse (hpmc):

Kapangidwe ka mankhwala:
HPMC ndi cellulose yochokera ku cellulose wachilengedwe kudzera mu kusintha mankhwala. Kapangidwe kake kamakhala ndi mayunitsi ophatikizira pamodzi, ndi methyl ndi hydroxypyl magulu omwe amaphatikizidwa ndi ena mwa magulu a hydroxyy pa mayunitsi a glucose. Kapangidwe ka mankhwala kumeneku kumapereka zinthu zapadera ku HPMC, ndikupangitsa kuti isungunuke m'madzi ndipo amatha kupanga ma viscous mayankho.

Katundu wathupi:
Madzi osungunuka: hpmc amasungunuka m'madzi, ndikupanga mayankho a colloidal ndi mafayilo apamwamba.
Kutha kwa makanema: Imatha kupanga mafilimu owoneka bwino, osungunuka akauma, zomwe zimathandizira kuti ndizothandiza komanso kaphiri.
Kukhazikika kwamafuta: hpmc kumawonetsa kukhazikika pamatenthedwe osiyanasiyana, ndikupangitsa kukhala koyenera kugwiritsa ntchito njira zosiyanasiyana, kuphatikizapo omwe ali m'makampani omanga.

2.Pasppastistion ya hpmc mu matope a simenti:

Kuthana ndi Kulimbana:
Kugwiritsa ntchito kugwirira ntchito: kuwonjezera kwa hpmc kwa matope a simenti kumawonjezera kugwirira ntchito pokonza madzi. Izi zimapangitsa kusakaniza kochulukirapo komanso kosasinthasintha, kufalitsa ntchito mosavuta panthawi yomanga.
Kuchepetsa tsankho ndi magazi: hpmc amachita ngati chofunda, kupewa kupatukana kwamadzi kuchokera ku simenti ya simenti. Izi zimachepetsa tsankho komanso magazi, potero amalimbikitsa coutheon ndi kukhazikika kwa matope.
Zotsatsa zosintha: Kapangidwe kake ka HPMC kumathandizira kutsatsa bwino pakati pa matope ndi gawo lapansi, zomwe zimapangitsa kulimbikitsa mphamvu ndi kukhazikika kwa zinthu zomwe zimapangidwa.
Kulamulidwa Nthawi: HPMC imathanso kusintha ndi nthawi ya matope a simenti, kumapereka kusinthasintha pakupanga madongosolo ndikulola kuwongolera bwino pa ntchito.

Njira Zochitikira:
Kuwongolera hydration: mamolekyulu a HPMC amalumikizana ndi mamolekyulu amadzi, ndikupanga malo otetezera mozungulira ma cemement. Izi zimabweza njira zamagetsi za simenti, zimalepheretsa kukangana ndikulola kuti pakhale kugwirira ntchito nthawi yayitali.
Tinthu tating'onoting'ono: hydrophilic chilengedwe cha HPMC imathandizira kufalikira mosiyanasiyana matonganisite, olimbikitsa kugawa yunifolomu ya simenti. Kufalitsa yunifolomu iyi kumathandizanso kusinthasintha ndi mphamvu yamatope.
Mapangidwe a filimu: pakuyanika,Hpmcamapanga kanema woonda pamwamba pa matope, ndikumanga tinthu tating'onoting'ono. Kanemayo amachita ngati chotchinga choletsa chinyontho komanso kuukira kwa mankhwala, kulimbikitsa kulimba komanso kukana matope ku zinthu zachilengedwe.

Hydroxypropyl me cellulose (hpmc) imagwira ntchito yowonjezera matope a simenti ya simenti, kupereka madongosolo osiyanasiyana, kuphatikizapo kubalalitsa kosinthana. Malo ake apadera, monga kusungunuka madzi, kuthekera kwamafilimu, komanso kukhazikika kwamatenthedwe, zimapangitsa kuti zikhale chinthu chofunikira kwambiri pamachitidwe omanga amakono. Mwa kulimbikitsa kugwirira ntchito, kutsatira, ndi ntchito zonse, hpmc kumathandizira kupanga nyumba zapamwamba kwambiri komanso zolimba.
