Hydroxypropyl Methylcellulose (HPMC) ni polymer karemano ikoreshwa cyane mubwubatsi, ubuvuzi, ibiryo nibindi bice. Mu nganda za sima, AnxinCel®HPMC ikoreshwa kenshi nk'inyongeramusaruro mu kuzamura cyane imikorere ya sima, no kuzamura imikorere, imikorere ndetse nubukomezi bwa nyuma bwivanze rya sima.
1. Ibiranga shingiro nuburyo bwibikorwa bya HPMC
HPMC ni imiti yimiti yabonetse muguhindura selile binyuze muri Ethylation, hydroxypropylation na methylation. Imiterere ya molekuline ikubiyemo amatsinda menshi ya hydrophilique na hydrophobique, ituma igira uruhare runini muri sisitemu ya sima. HPMC ifite uruhare rukurikira muri sima:
Ingaruka
HPMC ifite ingaruka zikomeye zo kubyimba kandi irashobora kuzamura cyane ubwiza bwa paste ya sima, bigatuma imvange ya sima iba imwe mugihe cyo kuvanga no kwirinda gutondeka cyangwa gutembera. Ibi nibyingenzi mugutezimbere amazi no gutuza kwa sima, cyane cyane mubikorwa bya beto ikora cyane cyangwa nibindi bikoresho bisaba sima, kugirango byuzuze neza kandi bifite ubucucike buri hejuru.
Kunoza gufata neza amazi
HPMC irashobora kugenzura neza igipimo cyuka cyamazi muri paste ya sima kandi igatinda igihe cyambere cyo gushiraho sima. Cyane cyane mubushyuhe bwinshi cyangwa ahantu humye, irashobora kugumana ubushuhe bwa paste ya sima kandi ikarinda gukama imburagihe, bityo bikanoza imikorere yubwubatsi. Kubika amazi ni umutungo wingenzi mubikorwa byo kubaka ibikoresho bya sima kandi birashobora gukumira neza imvune.
Kunoza gufatira hamwe no kongera amazi
Ibindi byongewemo imiti byongewe kumasima ya sima, nka polymers, imyunyu ngugu, nibindi, bishobora kugira ingaruka kumazi ya sima. HPMC irashobora kongera imbaraga zo guhuza sima, bigatuma shitingi irushaho kuba plastike namazi, bityo bigatuma ubwubatsi bukorwa. Byongeye kandi, HPMC irashobora kandi kongera imbaraga hagati ya sima nibindi bikoresho byubaka (nkumucanga na kaburimbo) kandi bikagabanya kugaragara kwamacakubiri.
Kunoza guhangana
Kubera ko AnxinCel®HPMC ishobora kunoza amazi ya sima no gutinza inzira yo kuyobya amazi, irashobora kandi kunoza neza guhangana n’ibikoresho bya sima. Cyane cyane mugihe cyambere iyo imbaraga za sima zitageze kurwego ruhagije, ibikoresho bya sima bikunda gucika. Ukoresheje HPMC, igipimo cyo kugabanuka kwa sima kirashobora gutinda kandi imvune zatewe no gutakaza amazi byihuse zirashobora kugabanuka.
2. Ingaruka za HPMC mugukoresha sima
Kunoza imikorere ya sima
Ingaruka yibyibushye ya HPMC ituma paste ya sima ikora neza. Kubwoko butandukanye bwa sima (nka sima isanzwe ya Portland, sima-yumisha vuba, nibindi), HPMC irashobora guhindura amazi ya slurry kandi ikorohereza gusuka no kubumba mugihe cyo kubaka. Byongeye kandi, HPMC irashobora gutuma paste ya sima ihagarara neza mugihe cyo kubaka, kugabanya ikirere, no kuzamura ubwiza bwubwubatsi muri rusange.
Kongera imbaraga za sima
Kwiyongera kwa HPMC birashobora kunoza imikorere ya sima kurwego runaka. Irahindura ikwirakwizwa ryamazi muri sima, iteza imbere uburyo bumwe bwoguhindura ibice bya sima, bityo bikazamura imbaraga zanyuma zo gukomera kwa sima. Mubikorwa bifatika, wongeyeho umubare ukwiye wa HPMC urashobora guteza imbere hydrata yambere ya sima kandi igatera imbaraga zo kwikuramo, guhindagurika no gukomera kwa sima.
Kuramba kuramba
Kwiyongera kwa HPMC bifasha kunoza uburebure bwa sima. Cyane cyane iyo sima ihuye nibidukikije byangirika (nka acide, alkali, saline, nibindi), HPMC irashobora kongera imiti irwanya imiti hamwe na sima irwanya sima, bityo ikongerera igihe cyumurimo wububiko bwa sima. Byongeye kandi, HPMC irashobora kugabanya capillary porosity yimvange ya sima kandi ikongera ubwinshi bwa sima, bityo bikagabanya umuvuduko wacyo mubi ahantu habi.
Kunoza imihindagurikire y’ibidukikije
Mugihe cyikirere gikabije, imikorere ya sima ikunze kwibasirwa nihinduka ryubushyuhe nubushuhe. HPMC irashobora gutinza igihe cyo gushiraho sima kandi ikagabanya ibibazo biterwa no gukama vuba cyangwa hydrated nyinshi. Kubwibyo, irakwiriye cyane cyane mubidukikije byubaka hamwe nubushyuhe bwo hejuru, ubushyuhe buke hamwe nubushyuhe bunini.
3. Gukoresha neza HPMC
Nubwo ikoreshwa rya HPMC muri sima rishobora kunoza imikorere yayo, imikoreshereze yaryo igomba kwitonda, cyane cyane mumafaranga yongeyeho. Kwiyongera cyane kwa HPMC birashobora gutuma ubwiza bwa paste ya sima buba hejuru cyane, bikavanga kuvanga kutaringaniye cyangwa ingorane zo kubaka. Mubisanzwe, umubare wa HPMC wongeyeho ugomba kugenzurwa hagati ya 0.1% na 0.5% bya misa ya sima, kandi agaciro kihariye kagomba guhinduka ukurikije ubwoko bwa sima bwihariye, ikoreshwa nibidukikije.
Inkomoko zitandukanye, ibisobanuro hamwe nimpinduka zaHPMC irashobora kandi kugira ingaruka zitandukanye kumiterere ya sima. Kubwibyo, mugihe uhitamo HPMC, ibintu nkuburemere bwa molekile, hydroxypropyl na methylation degre bigomba gutekerezwa byimazeyo kugirango ubone impinduka nziza. Ingaruka.
Nibihinduka byingenzi bya sima, AnxinCel®HPMC itezimbere cyane imikorere, imbaraga, kuramba hamwe n’imihindagurikire y’ibidukikije ya sima mu kubyimba, kunoza imikoreshereze y’amazi, kongera imbaraga no kurwanya ibimeneka. Gukoresha kwinshi mu nganda za sima ntabwo bizamura imikorere rusange ya sima gusa, ahubwo binatanga inkunga ikomeye mubushakashatsi no guteza imbere ibicuruzwa bishya bya sima nkibikorwa byo hejuru bikora neza kandi byubaka ibidukikije. Mugihe imishinga yubwubatsi ikomeje kongera ibyo isabwa mubikorwa bifatika, HPMC ifite amahirwe menshi yo gukoresha mubikorwa bya sima kandi izakomeza kuba inyongera yingenzi yo guhindura sima.
