Hydroxypropyl methylcelculose (hpmc)yindawo ye-semi-syburitic ye-polymer ye-polymer ye-polymer yenziwa kwi-selsulose yendalo ngokulungiswa kweekhemikhali. Isetyenziswe ngokubanzi kwindawo yamayeza, i-cosmetic, ukutya, ukwakhiwa kunye namanye amashishini. Inezixhobo ezigqwesileyo zomzimba kunye nekhemikhali, ezinokuhlaziywa zivela kwimiba ye-solity, uzinzo, iimpawu ze-viscosity, uzinzo lobushushu, njl.
I-1. Ukungasebenzi
I-solity ye-kimbacell®hpmc yenye yezinto zayo ezibalulekileyo zomzimba kunye neekhemikhali. Ingachithwa emanzini ukwenza isisombululo se-colloidal esibonakalayo. I-smolling inxulumene ngokusondeleyo nobunzima bayo kunye nenqanaba lokufakwa endaweni ye-hydroxyl kunye ne methyl. Ngokubanzi, i-HPMC ene-molecular ye-molecular iphosa ngokulula, ngelixa i-HPMC ine-molecular ephezulu iyanyibilika kancinci. Kwisisombululo esinamandla, i-HPMC ayisenzi ubume bobuchule bomeleleyo kwaye bonisa iimpawu zesisombululo esiqhelekileyo sePolymer. Ukongeza, i-HPMC ikwanokuqina okufanelekileyo kwezinye izinyibilikisi zezinto eziphilayo (ezinje ngotywala kunye neeKetones), nto leyo eyenza ukuba isetyenziswe ngokubanzi kwezinye iindawo ezikhethekileyo.
I-2. Iimpawu ze-viscosity
Ukuchithwa kwe-HPMC e-HPMC e-HPMC kungavelisa isisombululo seColodal sokomatiswahlukeneyo, kwaye ukubonwa kwayo kuchaphazeleka ikakhulu zizinto ezinjengokungafaniyo, isidanga sokufana, ukugxila kwi-HPMC. Njengoko uxinzelelo lwe-HPMC, i-viscosity yesisombululo inyuka kakhulu, kwaye i-viscosity yezisombululo ezenziwe yi-HPMC yeemolekyuli ezahlukeneyo zahluke kakhulu. Iipropathi ze-viscosity ye-HPMC yenza ukuba isetyenziswe ngokubanzi kumashishini okutya kunye nokutya, ngakumbi kulawulo lokukhutshwa kweziyobisi, ii-thi chulers kunye neearhente zeqela.
Kwisisombululo esinamandla, i-viscosity ye-HPMC ihlala incipha ngokukhulisa ubushushu obukhulayo, nto leyo ebonisa ukuba i-HPMC inobuthathaka. Xa iqondo lobushushu liphezulu kakhulu, ukubonwa kwesisombululo se-HPMC kunokuphumelela, oko kufuna ingqalelo eyodwa kwezinye iinkqubo.
3. Uzinzo lwe-therm
I-HPMC inozinzo oluhle lobufundisi ngaphakathi kuluhlu oluthile lobushushu. Uzinzo lwayo lwe-thermal luhambelana kakhulu nobunzima bemolekyuli, isidanga sokufakwa endaweni kunye neemeko zokusingqongileyo. Kwiqondo lokushisa eliqhelekileyo, isakhiwo se-MOLERUNE ye-HPMC sizinzile kwaye akukho lula ukubola. Nangona kunjalo, xa iqondo lobushushu liphezulu kakhulu, i-HPMC inokuthi ithathe inxaxheba ye-hydrolysis okanye i-DehydroxYyetion, echaphazela intsebenzo yayo.
Uzinzo lwe-HPMC lwenziwa ukuba lube nokusebenza kakuhle kwezinye iindawo zobushushu obuphakamileyo (njengokwendlela yokutya okanye yokwakha). Nangona kunjalo, xa iqondo lobushushu lidlula inqanaba elithile, ubume be-HPMC bunokuyonakala, kubangelwe kukonakala kwentsebenzo.
4. Uzinzo kunye nemvakalelo ye-pH
I-HPMC ibonisa uzinzo lweekhemikhali eziphantsi kweemeko ezahlukeneyo zePH. Ihlala izinzile phantsi kwe-acidic, engathathi hlangothi kwaye iphantsi kweemeko eziqinileyo ze-alkaline, imeko ye-Alkaline ye-Alkaline, i-molecular ye-kimbacell® inokuthi itshintshe, imphumo. Ke ngoko, kwizicelo ezithile, kubaluleke kakhulu ukuhlengahlengisa ixabiso le-pH ukulawula uzinzo lwe-HPMC.
Isisombululo se-HPMC sinemvakalelo ye-HPMC. Ingakumbi kwiimveliso zamayeza okanye zebhayiloji, i-HPMC ihlala isetyenziselwa ukulungiselela iifom zokukhutshwa kwe-iDosage kuba inokuba nexabiso elihlukeneyo le-PH. Le ndawo ibaluleke kakhulu kwinkqubo yokukhutshwa kweziyobisi kwaye inokulawula ukukhutshwa kweziyobisi.
I-5. Iipropathi zoomatshini
I-HPMC, njengezinto ze-polymer, inamandla athile oomatshini. Isisombululo se-AICO EYENZIWEYO EYENZIWEYO KWIZOBUCHULE ZAMANQAKU AMALUNGISELELO ALUNGISELELO NOKUFUNDA NGOKUGQIBELA. Ingakumbi xa usenza ifilimu, i-HPMC inokubonisa iipropathi ezintle zoomatshini. Oku kusenza ukuba ukubambelela ekubambelelekeni kwemozulu kunye nokungaxhathisi bemozulu xa kusetyenziswa njengemifanekiso yefilimu okanye i-thickener kwishishini lokwakha.
6. Ipropathi yeGell
I-HPMC inepropathi eqinileyo yokuthwala, ngakumbi ekugxininiseni okuphantsi, inokwenza inkqubo yokugcwalisa amanzi ngamanzi. Ukuziphatha kwayo geling kunxulumene ngokusondeleyo nobunzima bayo, uhlobo kunye nokuxinana kwempahla yokutshintsha. Phantsi kweemeko ezifanelekileyo, i-HPMC inokusetyenziswa njenge-thianer, iarhente yeglasi okanye i-mulsifier, eyenza isetyenziswe ngokubanzi ekutyeni, amayeza, cosmetics kunye namanye amasimi.
7. Umsebenzi womphezulu
I-HPMC inomsebenzi othile womphezulu kuba iqulethe amaqela e-hydrophobic kunye ne-hydrophobic. Phantsi kweemeko ezithile, i-kimbacell®hpmc inokunciphisa uxinzelelo lolwelo lolwelo kwaye isetyenziswe njenge-surfacnt. Kwii-chimeceticals kunye ne-cosmetics, i-HPMC isetyenziswa ngokubanzi njengomntu ongu-emulsifier kwaye osasazekileyo, onokukhuthaza ukuxutywa kwamanzi ioyile kwaye aphucule uzinzo lwemveliso.
8. I-BioMPiatise
I-HPMC ine-bimoMPini elungileyo kwaye isetyenziswa ngokubanzi kwintsimi ye-biodical. Ayigqalwa lula kwaye ingene emzimbeni kwaye ihlala isetyenziswa njengesixhobo sokukhupha iziyobisi okanye ukulungiselela iicaphules zeziyobisi. Ngenxa yempawu zayo eziphezulu zemolekyuli, i-HPMC ihlala ingabi kubangeli iimpendulo zomzimba okanye ezinye iziphumo kwaye ilungele ukulawulwa kweziyobisi ngeendlela ezahlukeneyo ezinjengenziweyo, ezinesihloko kunye nenaliti.
I-HPMCInezinto ezigqwesileyo zomzimba kunye nekhemikhali, kubandakanya ukubenzela imichiza, i-viscosity eguquguqukayo, uzinzo lwe-subrm, uzinzo lwekhemikhali kunye nokuzinza kwemichiza kunye ne-biomatise. Ezi ndawo zenza ukuba zisetyenziswe ngokubanzi kumashishini amaninzi anje ngamayeza, ukutya, i-cosmetics nolwakhiwo. Ukuqonda okunzulu kweepropathi zayo zomzimba kunye nekhemikhali kuya kunceda ekuqulunqweni iziphumo zazo zokwenza isicelo kwimimandla eyahlukeneyo.
