Ukuthandwa kweHydroxypropyllylylylylylylyll methylcellulose ulwazi lwe-methylcellulose hpmc

IHydroxypropyl Methylcellose HPMC i-ether engeyona eye-cellulose eyenziwe nge-polymer mattule cellulose ngochungechunge lokucutshungulwa kwamakhemikhali. Bangamaphunga, angenambisi futhi angenambitha futhi avuvukala emanzini abandayo aya kusixazululo esicacile noma esincane se-colloidal. Inezakhiwo zokuqina, ukubopha, ukusabalalisa, ukusabalalisa, ukwakha amafilimu, ukumisa ama-adsorbing, ukugcinwa phansi, indawo esebenzayo, ukugcina umswakama nokuvikela umswakama. I-Hydroxypropylm methylcellulose, i-methylcellulose ingasetshenziswa ezintweni zokwakha, imboni yezenhlaya, i-sonthetic resin, imboni ye-ceramics, imishanguzo, umuthi, ezolimo, amakhemikhali nsuku zonke kanye nezinye izimboni.

Umphumela wokugcina amanzi kanye nomgomo we-hydroxypropyllllykylylylylyly hpmc

I-Celsulose Ether HPMC ikakhulukazi idlala indima yokugcinwa kwamanzi futhi ikhule ku-pement datair kanye ne-gypsum esekelwe ku-slurry, ongathuthukisa kahle ukubumbana nokuphikisana nokuqina kwe-slurry.

Izici ezinjengokushisa komoya, izinga lokushisa nokucindezela komoya lizothinta izinga lokuzithambisa kwamanzi emikhiqizweni yodaka kasimende nemikhiqizo esekwe e-gypsum. Ngakho-ke, ngezinkathi ezahlukahlukene zonyaka, kukhona umehluko othile emthethweni wokugcina amanzi wemikhiqizo ngenani elifanayo le-HPMC elingeziwe. Ekwakhiweni okuthize, umphumela wokugcinwa kwamanzi we-slurry ungashintshwa ngokwanda noma ukwehlisa inani le-HPMC elingeziwe. Ukugcinwa kwamanzi kwe-methyl cellulose ether ekushiseni okuphezulu kuyinkomba ebalulekile yokuhlukanisa ikhwalithi ye-methyl cellulose ether. Imikhiqizo emihle yochungechunge lwe-HPMC ingaxazulula inkinga yokugcinwa kwamanzi ngaphansi kokushisa okuphezulu. Esikhathini sokushisa esiphakeme, ikakhulukazi ezindaweni ezishisayo nezomile kanye nokwakhiwa kwesendlalelo ohlangothini olunelanga, i-HPMC esezingeni eliphakeme iyadingeka ukuthuthukisa ukugcinwa kwamanzi kwe-slurry. I-HPMC esezingeni eliphakeme, ngokufana okuhle, amaqembu ayo we-methopp kanye ne-hydroxypropoxy asatshalaliswa ngokulandelana kwama-athomu ama-athomu asolaka ama-athomu asomathe ama-hydrogel, ukuze akwazi ukuhambisa amanzi okushisa okubangelwa isimo sezulu esiphakeme futhi athole ukugcinwa kwamanzi okuphezulu.

I-cellulose hpmc ephezulu ye-cellulose HPMC ingahlakazeka ngendlela efanayo nangokufanelekile kwimikhiqizo esekwe omanzini nemikhiqizo esekwe e-gypsum, futhi ihlanganise zonke izinhlayiya, futhi yakha ifilimu eliqinile, futhi umswakama osesisekelweni udedelwa kancane kancane isikhathi eside. Ukusabela kwe-hydration kokuqukethwe okuhlanganisiwe kwenzeka, ngaleyo ndlela kuqinisekiswe amandla okuqinisa namandla acindezelayo wezinto ezibonakalayo. Ngakho-ke, ekwakhiweni okushisa okuphezulu kwehlobo, ukuze kufinyelelwe umphumela wokugcinwa kwamanzi, kuyadingeka ukwengeza imikhiqizo ye-HPMC ephezulu ngokuya ngefomula, ngaphandle kwalokho, ukuncishiswa kwamandla, ukuqhekeka, ukuqhekeka, ukuqhekeka, ukuwa nokuwa nokuwa okubangelwa ukomisa okusheshayo. Iphinde yandise ubunzima bokwakhiwa kwabasebenzi. Njengoba izinga lokushisa lincipha, inani lokungezwa le-HPMC lingancishiswa kancane kancane, futhi imiphumela efanayo yokugcina amanzi ingatholakala.

Ukugcinwa kwamanzi kweHydroxyproppropylylylylylylylylylyl hpmc umkhiqizo uqobo uvame ukuthinteka yizinto ezilandelayo:

1. I-cellulose ether hpmc homogeneity
I-HPMC ephendulwe ngokufanayo inokusatshalaliswa okufanayo kwamaqembu e-methoxy ne-hydroxypropoxy kanye nokugcinwa kwamanzi okuphezulu.

2. I-cellulose ether hpmc Thermal gel lokushisa le-gel
Ukushisa okushisa kakhulu kwe-gel lokushisa, kuphakama inani lokugcinwa kwamanzi; Ngaphandle kwalokho, ukwehlisa inani lokugcinwa kwamanzi.

3. I-cellulose ether hpmc viscosity
Lapho i-viscosity ye-HPMC inyuka, inani lokugcina amanzi liyanda; Lapho i-viscosity ifinyelela ezingeni elithile, ukwanda kwamazinga okugcina amanzi kuvame ukuba mnene.

4. I-cellulose ether hpmc yengeze yezengezo
Kukhudlwana inani elingeziwe le-cellulose ether hpmc, kuphakama inani lokugcinwa kwamanzi kanye nokuba ngcono ukugcinwa kwamanzi. Ebangeni le-0.25-0.6%, inani lokugcinwa kwamanzi likhuphuka ngokushesha ngokwanda kwenani lokungezwa; Lapho inani lokungezwa libuye lenyuka, umkhuba owandayo wamanani okugcinwa kwamanzi uya ngokuya kancane.
