Indawo ephantsi yeHydroxypropyl Methylcellulose (HPMC) luhlobo lweseliulose ephuma kwi-cellulose edla ngokusetyenziswa kumashishini ahlukeneyo, kubandakanywa amayeza, ulwakhiwo, ukutya, kunye nezinto zokuthambisa.Ithathwe kwi-cellulose, eyipolymer yendalo efumaneka kwizityalo.I-HPMC ilungiswa ngokusabela kweekhemikhali ukuphucula iimpawu zayo kwizicelo ezithile.I-HPMC ene-low-placement idla ngokuba ne-DS esezantsi xa kuthelekiswa ne-HPMC eqhelekileyo, ekhokelela kwiimpawu ezahlukeneyo kunye nokusebenza kwizicelo ezahlukeneyo.
Iimpawu ze-HPMC yokuTshintsha indawo ePhantsi:
Ubume be-Hydrophilic: Njengezinye izinto eziphuma kwi-cellulose, i-HPMC ene-low-placement yi-hydrophilic, oku kuthetha ukuba inobudlelwane namanzi.Le propati yenza ukuba ifaneleke kwizicelo apho ukugcinwa komswakama, ukuqina, okanye iipropati zokwenza ifilimu zifunwa.
Uzinzo lwe-Thermal: I-HPMC ibonisa uzinzo oluhle lwe-thermal, iyenza ilungele ukusetyenziswa kwimixube eyenziwa ngokulungiswa okanye ukuvezwa kubushushu obuphezulu.
Ubuchule bokwenza iFilimu: I-HPMC ene-low-replacement inokwenza iifilimu ezicacileyo kunye neziguquguqukayo xa zomile, nto leyo eyenza ibe luncedo kumashishini ahlukeneyo, kubandakanywa amayeza kunye nokutya, kwiipilisi zokugquma okanye izithako ezifakelweyo.
Ukutyeba kunye nokuguqulwa kweRheology: I-HPMC yi-arhente esebenzayo yokuqina kwaye inokuguqula i-rheology yezisombululo ezimanzi.Kwifom yokutshintshwa ephantsi, ibonelela ngokuphucula i-viscosity ephakathi, ivumela ulawulo oluchanekileyo kwiipropati zokuhamba kwezinto zokuqulunqa.
Ukuhambelana kweMichiza: Ihambelana noluhlu olubanzi lwezinye izithako eziqhelekileyo ezisetyenziswa ekuqulunqweni, kubandakanywa neetyuwa, iswekile, i-surfactants, kunye ne-solvents eziphilayo.Oku kuguquguquka kunegalelo ekusetyenzisweni kwayo ngokubanzi kumashishini ahlukeneyo.
Ubume be-Non-Ionic: I-HPMC ye-low-replacement ayikho i-ionic, oku kuthetha ukuba ayithwali intlawulo yombane kwisisombululo.Le propati ivumela ukuhambelana noluhlu olubanzi lwezinye iikhemikhali kunye nokunciphisa umngcipheko wokusebenzisana okunokuthi kuthintele ukuzinza okanye ukusebenza kokuqulunqwa.
I-Biodegradability: Ithathwe kwi-cellulose, i-HPMC i-biodegradable phantsi kweemeko ezifanelekileyo, nto leyo ebaluleke kakhulu ingqalelo kwizicelo zendalo.
Usetyenziso lwe-HPMC yoTshintsho oluPhantsi:
Amachiza:
I-Tablet Coating: I-HPMC ene-low-replacement ingasetyenziselwa ukwenza i-uniform kunye neengubo zokukhusela kwiipilisi, ukubonelela ngokukhululeka okulawulwayo okanye ukufihla ukunambitha.
Iifomyula eziLawulwayo zokuKhululwa: Isetyenziselwa kwiinkqubo ze-matrix ukwenzela ukukhululwa okuqhubekayo okanye okulawulwayo kwezithako ezisebenzayo zamachiza.
Izisombululo ze-Ophthalmic: I-HPMC iqeshwe kwi-eye drops kunye ne-ointments ngenxa yeempawu zayo ze-mucoadhesive kunye nokuhambelana nezicubu ze-ocular.
Ulwakhiwo:
I-Tile Adhesives: I-HPMC isebenza njenge-ejenti yokuqina kunye nokugcinwa kwamanzi kwi-adhesives ye-tile, ukuphucula ukusebenza kunye neempawu zokubambelela.
Udaka olusekwe kwisamente: Ukwandisa ukusebenza, ukugcinwa kwamanzi, kunye nokunamathela kwiidaka ezenziwe ngesamente, ezifana ne-renders, plasters, kunye ne-grouts.
IiMveliso zeGypsum: I-HPMC enendawo ephantsi iphucula ukungaguquguquki kunye nokusebenza kweemveliso ezisekwe kwigypsum njengeekhompawundi ezidityanisiweyo kunye neeplasta eludongeni.
Ukutya kunye neziselo:
I-Emulsions kunye nokuSuspensions: I-HPMC izinzisa i-emulsions kunye nokumiswa, ukuthintela ukuhlukana kwesigaba kunye nokuphucula ukuthungwa kunye nomlomo weemveliso zokutya.
Iimpahla ezibhakiweyo: Iphucula i-viscosity yentlama, ukuthungwa, kunye nobomi beshelufu kwizinto ezibhakiweyo njengesonka, iikeyiki kunye neepastries.
Iimveliso zobisi: I-HPMC ingasetyenziswa kwizicelo zobisi ezifana neyogathi kunye ne-ayisikrimu ukuphucula uzinzo kunye nokuthungwa.
Ukhathalelo loBuqu kunye neZithambiso:
