Katundu wa hydroxypropyl methl cellulose ether ether ether

Monga imodzi mwazofunikira pa cellulose emeurs mu matope a ufa wa ufa, hydroxypropyl wa methylcellulose ali ndi ntchito zambiri matope. Udindo wofunikira kwambiri wa hydroxpyl methylcellulose mu matope a simenti ndi madzi osungira ndi kukula. Kuphatikiza apo, chifukwa kulumikizana kwake ndi simenti dongosolo, kumathanso kusewera ntchito yothandiza pamlengalenga, kutaya kukhazikitsa, ndikuwongolera mphamvu yaundana. Zotsatira.

Kugwiritsa ntchito kofunikira kwambiri kwa hydroxypropyl methylcellulose kuti matope ndi madzi. Monga ma cellulose entose ku matope, hydroxypropyll methylcellulose ingagwiritsidwe ntchito pafupifupi matope onse, makamaka chifukwa chosunga madzi. Nthawi zambiri, kugwiritsa ntchito madzi kwa hydroxypropyl methylcellulose ndikukhudzana ndi mawonekedwe ake, kuchuluka kwa cholowa m'malo mwake.

Hydroxypylpyl amagwiritsidwa ntchito ngati thicyllulose, ndipo zotsatira zake zakumwamba zimakhudzana ndi kuchuluka kwa miyeso, kukula kwa tinthu, ma vidiyo komanso ma detimentlfellulose. Nthawi zambiri, kuchuluka kwa gawo la kuloweza ndi kukweza kwa cellulose ether, ndi kocheperako tinthu tating'onoting'ono.

Mu hydroxypropyl methylcellulose, kuyambitsa kwa methoxy magulu kumachepetsa mphamvu yam'madzi okhala ndi methylcroselosell, kotero kuti hydroxypropyll meth, kotero kuti hydroxypropylll, kotero kuti hydroxypropylll, kotero kuti hydroxypropylll, kotero kuti hydroxypropyllll, ndiye kuti hydroxypropyl Yambitsani mankhusu oyenera a mpweya mu matope, chifukwa cha "mpira wamphamvu" wa thovu la mpweya,

Kuchita zomanga kwa matope kumakonzedwa, ndipo nthawi yomweyo, kuyambitsa kwa mafupa kumawonjezera kuchuluka kwa matope. Inde, kuchuluka kwa mpweya womwe umafunikira kulamuliridwa. Cholemba kwambiri cha mpweya chimakhala ndi vuto lamphamvu kwa matope.

Hydroxypylpyl a Methylcellulose adzazengereza kukhazikitsa simenti, potero ndikuchepetsa mapangidwe a simenti, koma izi sizabwino matope m'magawo ozizira.

Monga polymer chinthu chotalika, hydroxypropyl, meth methylcellulose imatha kukonza zolimbitsa thupi ndi gawo litawonjezeredwa ndi simenti pansi pa chinyezi.

Kuwerenga, kugwira ntchito kwaHpmcMu matope makamaka akuphatikiza: kusungidwa kwamadzi, kukulira, kutalika kwakhazikitsa nthawi, mpweya woopsa ndikuwongolera mphamvu yayikulu, etc.
