Makulidwe wamba omwe ali mu hpmc pomanga mapulogalamu
1 Kuyamba
Hydroxypylfelllulose (hpmc) ndi chowonjezera chowonjezera ndipo chimagwiritsidwa ntchito ndi matope osiyanasiyana, omata ufa, kusunthika kwamadzi, ndi kukonza zomangamanga. Kuchita kwake kumadalira kwakukulu pakuwoneka. Nkhaniyi ifotokoza mwatsatanetsatane ma vikiti omwe amawoneka ngati hpmc mu kapangidwe ka HPMC munthawi zosiyanasiyana komanso momwe amathandizira pantchito yomanga.
2. Makhalidwe oyambira a HPMC
HPMC ndi njira yopanda madzi osungunuka yamadzi ya ether ether ether yopezedwa ndi kusintha kwa mankhwala a cellulose yachilengedwe. Ili ndi zinthu zotsatirazi:
Kukula: HPMC imatha kuwonjezera mafayilo omanga ndikupereka ntchito zabwino.
Kusungidwa kwamadzi: Kuchepetsa bwino madzi ndikusintha ma hydration kugwirira ntchito kwa simenti ndi gypsum.
Thuma: limapangitsa kuti zinthu ziziyenda bwino panthawi yomanga komanso kosavuta kugwiritsa ntchito.
Katundu wopanga makanema: Kanema wopangidwa umakhala ndi mphamvu yabwino komanso kusinthasintha ndipo amatha kusintha zinthu zomwe zili.
3. Kugwiritsa ntchito HPMC pakumanga zida
Tile zomatira: Udindo waukulu wa HPMC mu tile zomatira ndikuwongolera kulimbikira ndi nthawi yotseguka. Kuchulukitsa kwa ma Iscceckera nthawi zambiri kumakhala pakati pa 20,000 ndi 60,000 kukhalamo kuti apereke katundu wabwino komanso nthawi yotseguka. Kukwera kwambiri HPMC kumathandizira kukulitsa kulimba kwa tile kumalimbikitsa ndikuchepetsa.
Pukuta la putty: pakati pa ufa wotsimikizira, hpmc makamaka imagwiritsa ntchito gawo la kusungidwa kwamadzi, mapangidwe ndikuwongolera kugwirira ntchito. Makutu nthawi zambiri amakhala pakati pa 40,000 ndi 100,000 a MPPIM. Maonekedwe apamwamba amathandizira kusungira chinyezi mu ufa wa putty, kukonza nthawi yake yomanga ndi yosalala.
Matope owuma: hpmc amagwiritsidwa ntchito pouma matope osakaniza kuti apititsetse zomatira ndi zida zamadzi. Maonekedwe wamba m'matumba ali pakati pa 15,000 ndi 75,000 Mpachi. Mu zochitika zosiyanasiyana zofunsira, kusankha kwa HPMC ndi ma visction yoyenera kumatha kukulitsa magwiridwe antchito ndi kusungidwa kwamadzi kwa matope.
Matope okhaokha: Kuti matope omwe amadzilimbitsa okha ali ndi madzi abwino, mafano a HPMC nthawi zambiri amakhala pakati pa 20,000 ndi 60,000 a MPPIM. Ma utoto a ma Iscccinwa amatsimikizira kuti matopewo ali ndi madzi okwanira osakhudza mphamvu atachiritsidwa.
Kuphimba kwamadzi: mumadzi ovala madzi a HPMC ali ndi mphamvu yayikulu pa zokutira ndi katundu wamafilimu. HPMC yokhala ndi mawonekedwe a pakati pa 10,000 ndi 50,000 nthawi zambiri amagwiritsidwa ntchito kuonetsetsa kuti madzi abwino ndi opanga mafilimu.
4. Kusankha kwa HPMC
Kusankhidwa kwa ma visc makamaka kumadalira gawo lake pakugwiritsa ntchito ndi zomangamanga. Nthawi zambiri, mamasukidwe apamwamba a HPMC, yabwino kwambiri yolimbitsa thupi ndi kusungidwa kwamadzi, koma mafano ambiri angayambitse zovuta zomanga. Chifukwa chake, kusankha kwa HPMC yokhala ndi mawonekedwe oyenera ndiye njira yopezera zotsatira za zomanga.
Kukula Kwakukulu: HPMC yokhala ndi mafayilo apamwamba ali ndi mphamvu yokulirapo ndipo ndiyoyenera kugwiritsa ntchito zomatira kwambiri, monga holo yamatayala ndi ufa.
Magwiridwe Osunga Madzi: HPMC yokhala ndi ma visccy apamwamba ndi abwino kwambiri mu chinyezi ndipo ndi yoyenera kuti musunge chinyontho kwa nthawi yayitali, monga matope osakaniza owuma.
Kugwira ntchito: Pofuna kukonza kugwiritsidwa ntchito kwa zinthuzo, mafati oyenera amathandizira kukonza maopaketso omanga, makamaka m'matavala odzilimbitsa okha.
5. Zinthu zomwe zikukhudza mafayilo a HPMC
Ma digiri ya polymerization: Wokwera pamlingo wa polymerization wa HPMC, ma visc. Ntchito zosiyanasiyana zimafuna kusankha kwa HPMC yokhala ndi madigiri osiyanasiyana a polymerization kuti mukwaniritse zabwino.
Njira Yothetsera: Kuzunzidwa kwa HPMC m'madzi kudzakhudzanso mafayilo. Nthawi zambiri, kuchuluka kwa njira yothetsera vutoli, mafayilo akulu.
Kutentha: Kutentha kumakhala ndi vuto lalikulu pakukweza kwa HPMC. Nthawi zambiri, mafayilo a mayankho a HPMC amachepetsa pamene kutentha kumawonjezeka.
Monga chowonjezera chofunikira pomanga zida zomangira, mafakisoni a HPMC amakhudza kwambiri ntchito yomanga ndikugwiritsa ntchito zotsatira zomaliza. Mawonekedwe a ma viscc amasiyanasiyana pakati pa mapulogalamu, koma nthawi zambiri amakhala pakati pa 10,000 ndi 100,000 a Rop. Mukamasankha HPMC yoyenera, ndikofunikira kuganizira momwe mafakitsire amafananira chifukwa cha zofunikira ndi zofunikira, kuti mukwaniritse bwino ntchito.
