IHydroxypropyl Methyl Cellulose (HPMC)
IHydroxypropyl methyl cellulose, yenza lula i-propyl methyl cellulose (i-HPMC hydroxypropylmethylcellulose, isifinyezo), ifanele ibe yeyodidi oluxubeneyo lwe-cellulose ether engeyo-ionic. Yi-semi-synthetic, engasebenziyo, i-viscoelastic polymer edla ngokusetyenziswa kwi-ophthalmology njenge-lubricant, okanye njenge-excipient okanye i-excipient kumayeza omlomo, edla ngokufunyanwa kwiintlobo ngeentlobo zeemveliso. Iselulosi yeHydroxypropyl ingasetyenziswa njengesongezo sokutya, i-emulsifier, i-thickener, i-agent yokunqunyanyiswa kunye ne-gelatin yezilwanyana.
IZINTO INGCACISO Imbonakalo Umgubo oMhlophe Ukubola kobushushu 200min Ubushushu bokutshintsha kwemibala 190-200℃ Viscosity 400 PH Ixabiso 5~8 Ukuxinana 1.39g/cm3 Ubushushu beCarbonization 280-300℃ Uhlobo Ibakala lokutya Umxholo 99% Uxinzelelo lwangaphezulu I-42-56dyne / cm ye-2% isisombululo samanzi -
IHydroxypropyl Methylcellulose (MHPC)
IHydroxypropyl methylcellulose (MHPC) azinavumba, azinancasa, azinatyhefu ii-cellulose ethers eziye zanamaqela e-hyrdroxyl kwikhonkco leselulosi endaweni yeqela le-methoxy okanye le-hydroxypropyl enokunyibilika kakuhle kwamanzi. I-HPMC F60S yibakala eliphezulu le-viscosity esetyenziswa njenge-thickener, i-binder, kunye nefilimu yangaphambili kwi-agrochemicals, i-coatings, i-ceramics, i-adhesives, i-inki, kunye nezinye izicelo ezahlukeneyo.

Iselulosi yeHydroxyethyl (HEC)
I-Hydroxyethyl Cellulose (HEC) yi-non-ionic, i-polymer enyibilikayo emanzini ephuma kwi-cellulose ngoluhlu lweenkqubo zemichiza kunye nezomzimba. I-HEC ngumgubo omhlophe ukuya kokukhanya okutyheli, ongenavumba kunye nongenancasa, onyibilika ngokulula emanzini ashushu okanye abandayo ukwenza i- i-viscous gel solution.Xa i-pH kwisisombululo se-2 ukuya kwi-12, isisombululo sizinzileyo.Kuba iqela le-HEC liyi-nonionic enye kwisisombululo samanzi, aliyi kusabela kunye nezinye i-anion okanye i-cations kunye nokungakhathali kwiityuwa.
Kodwa i-molecule ye-HEC iyakwazi ukuvelisa i-esterification, i-etherification, ngoko ke kunokwenzeka ukuba iyenze inganyibiliki emanzini okanye iphucule iimpawu zayo.I-HEC nayo inamandla okwenza ifilimu kunye nomsebenzi ongaphezulu.
