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 njengesongezelelo sokutya, i-emulsifier, i-thickener, i-agent yokumiswa 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 lobuso I-42-56dyne / cm ye-2% isisombululo samanzi -
IHydroxypropyl Methylcellulose HPMC/HEC/MHPC
I-Hydroxypropyl methylcellulose, eyaziwa ngokuba yi-hypromellose, yenye ye-non-ionic cellulose exutywe ethers.Iyi-semi-synthetic, engasebenzi, i-viscoelastic polymer, edla ngokusetyenziswa njenge-lubricant kwi-ophthalmology, okanye njenge-excipient okanye i-excipient kwiyeza lomlomo.
Iyanyibilika emanzini kunye nezinye izinyibilikisi, ezifana ne-ethanol/amanzi, ipropanol/amanzi ngokwemilinganiselo efanelekileyo.Isisombululo samanzi sinomsebenzi ongaphezulu.Ukucaca okuphezulu kunye nokusebenza okuzinzileyo.Iimpawu ezahlukeneyo zeemveliso zinamaqondo okushisa e-gel ahlukeneyo kunye notshintsho lwe-solubility kunye ne-viscosity.I-viscosity ephantsi, i-solubility enkulu.Iinkcukacha ezahlukeneyo ze-HPMC zineentsebenzo ezahlukeneyo.Ukuchithwa kwe-HPMC emanzini akuchatshazelwa yi-pH.

IHydroxypropyl Methyl Cellulose HPMC F60S Yesamente esekwe kwiTile yokuncamathelisa udaka cps 400-200,000
IHydroxypropyl methylcellulose (HPMC) azinavumba, azinancasa, azinatyhefu ii-ether zeselulosi ebezinamaqela 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 izinto ezahlukeneyo zokusebenza.
