HydroxyPropyl methylcellse (HPMC) ni polymer ikoreshwa amazi ikoreshwa cyane mubikoresho byubaka, cyane cyane ingwate ishingiye kuri sima. Imiterere idasanzwe yimiti hamwe numutungo wumubiri wa HPMC, bikagira uruhare runini mugutezimbere uburomu, imikorere yubwubatsi, hamwe niramuco yingirakamaro.
(1) Ubumenyi bwibanze bwa HPMC
1. Imiterere yimiti ya HPMC
HPMC ni ko bakomoka kuri selile byabonetse muguhindura imiti ya selile. Imiterere yayo ikozwe ahanini na Methaxy (-OCH₃) na HydroxyPropoplexy (-CH₂chohch₃) Amatsinda asimbuza amatsinda ya hydroxyl kuri seligi. Iyi miterere iha Hpmc ubushobozi bwubusa nubushobozi bwo kurya.
2. Ibintu byumubiri bya HPMC
Gukemurwa: HPMC irashobora gushonga mumazi akonje kugirango akore igisubizo cya colloidared kandi gifite hydration nziza nubushobozi bwo kubyimba.
Umuti: Igisubizo cya HPMC kizakora gel iyo gushyuha ugasubira mubice byamazi nyuma yo gukonja.
Igikorwa cyo hejuru: HPMC ifite ibikorwa byiza byo hejuru mubisubizo, bifasha gukora imiterere ihamye.
Iyi miti idasanzwe yumubiri na shimi ituma hpmc ibikoresho byiza byo guhindura tile ishingiye kuri sima.
(2) Uburyo bwa HPMC buzamura imikorere yimyandikire ya sima ishingiye
1. Kunoza ihohoterwa rishinzwe kugumana amazi
Ihame: HPMC ikora imiterere ya viscous mumiti, ishobora gufunga neza mubushuhe. Ubu bushobozi bwo kugumana amazi biterwa numubare munini wamatsinda ya hydrophilic (nka hydroxyl matsinda) muri molekile ya HPMC, ishobora gukuramo no kugumana ubushuhe bunini.
Kunoza Adhesion: Imyifatire ya sima ishingiye ku nyungu zisaba ubuhehere mu kwitabira hydration reaction mugihe cyimikorere ikomeye. HPMC ikomeza kuba ahantu heza, kwemerera sima kwikuramo byuzuye, bityo bigatuma amazina afatika.
Kugura igihe: Gufata amazi birinda ibifatika kuva byumye mugihe cyo kubaka, kwagura igihe cyo guhinduka.
2. Kunoza imikorere yubwubatsi
Ihame: HPMC ifite ingaruka nziza yijimye, kandi molekile zayo zirashobora gukora imiterere yumuyoboro mubisubizo bitangaje, bityo byongera vicosiya.
Kunoza umutungo wo kurwanya urwanya: Gutandukanya Byinshi bifite imitungo myiza yo kurwanya mu buryo bwubaka, kugirango amabati adashobora kuguma mumwanya wateganijwe mugihe cyabujijwe.
Kunoza Amazi: Ubukwe bukwiye butuma ibintu byoroshye gusaba no gukwirakwira mugihe cyo kubaka, kandi icyarimwe bifite akazi keza, kugabanya ingorane zo kubaka.
3. Gutezimbere kuramba
Ihame: HPMC yongera kugumana amazi no gusohora ibifatika, bityo yongeza iherezo ryimikorere ya sima ishingiye kuri sima.
Kunoza imbaraga zo guhuza amakuru: sima yuzuye ya sigrate itanga igitangaza gikomeye kandi ntabwo ikunda kugwa cyangwa gucika intege mugihe kirekire.
Gutezimbere Kurwanya Crack: Hanze Amazi meza yirinda kugabanuka gukomeye kwibifata mugihe cyo kumisha, bityo bigabanya ikibazo cyo gucika intege cyatewe no kugabanuka.
(3) Inkunga ya Data
1. Gufunga amazi
Ubushakashatsi bwerekanye ko umubare wo kugumana amazi ashingiye kuri sima ashingiye ku kwiyongera kwa HPMC byateye imbere cyane. Kurugero, ongeraho 0.2% HPMM kumyifatire irashobora kongera urugero rw'amazi kuva kuri 70% kugeza 95%. Uku kunoza ningirakamaro kugirango utezimbere imbaraga zinkazi ndetse nigihe kirekire cyo kugendera.
2. Ikizamini cya STCcosity
Umubare wa HPMC wongeyeho ufite ingaruka zikomeye kuri viscosiya. Ongeraho 0.3% HPMC kuri sima ishingiye kuri sima ifatika irashobora kongera virusire inshuro nyinshi, kureba ko impeshyi ifite ibintu byiza byo kurwanya imikorere no guswera.
3. Ikizamini cya Bond
Binyuze mu bushakashatsi bugereranya, wasangaga imbaraga zingana hagati ya tile n'ibice by'ibisimba birimo hpmc byiza cyane kuruta ibyo bifatika bitagira HPMC. Kurugero, nyuma yo kongeramo 0.5% HPMC, imbaraga zo guhuza zirashobora kwiyongera kuri 30%.
(4) Ingero zisaba
1. Kurambika amabati hamwe n'amabati
Mu kurambura hasi amabati no mu makariso, fime ya epmc-yazamuye neza. Mugihe cyubwubatsi, ibifatika ntabwo byoroshye gutakaza amazi vuba, kwemeza ko nubwubatsi nuburinganire bwa tile.
2. Sisitemu yo kugenzura urukuta
HPMC-Yongerewe ingirakamaro kandi ikoreshwa cyane muri sisitemu yo kugenzura urukuta hanze. Kugumana amazi meza kandi ahisha kwemeza umubano ukomeye hagati yubuyobozi bwisuku nurukuta, bityo bigatuma iherezo rya sisitemu yo kwigomeka hanze.
Gusaba HPMC muri sima ishingiye ku nyenga ishingiye ku buryo butezimbere imikorere yimyitozo. Mugutezimbere amazi, kuzamura imikorere yubwubatsi no kunoza iherezo, HPMC ikora igihe cya sima ishingiye ku ikodeshwa ibereye ibyo bakeneye bigezweho. Hamwe no guteza imbere ikoranabuhanga no kwiyongera kwimikoreshereze yimikorere yo kubaka imikorere, porogaramu ya HPMC izaba yagutse.
