IHydroxypropyl Methyl Cellulose (HPMC)
IHydroxypropyl methyl cellulose, yenza lula i-propyl methyl cellulose (i-HPMC hydroxypropylmethylcellulose, isifinyezo), izoba ingxenye yenhlanganisela ye-non-ionic cellulose ether.Kuyi-semi-synthetic, engasebenzi, i-viscoelastic polymer evame ukusetshenziswa ku-ophthalmology njengento yokuthambisa, noma njengesamukeli noma isakhi emithini yomlomo, evame ukutholakala ezimpahleni eziningi ezihlukahlukene.I-Hydroxypropyl cellulose ingasetshenziswa njengesengezo sokudla, i-emulsifier, i-thickener, i-ejenti yokumiswa kanye ne-gelatin yezilwane esikhundleni.
IZINTO IMICIMBI Ukubukeka Impushana Emhlophe I-Decomposition Temperature 200min I-Discoloration Temperature 190-200 ℃ I-Viscosity 400 PH Inani 5~8 Ukuminyana 1.39g/cm3 Izinga lokushisa le-carbonization 280-300 ℃ Uhlobo Ibanga lokudla Okuqukethwe 99% Ukushuba kobuso 42-56dyne/cm yesixazululo esinamanzi esingu-2%. -
IHydroxypropyl Methylcellulose HPMC/HEC/MHPC
IHydroxypropyl methylcellulose, eyaziwa nangokuthi i-hypromellose, ingenye ye-non-ionic cellulose exubile ethers.Iyi-semi-synthetic, engasebenzi, i-viscoelastic polymer, evame ukusetshenziswa njengesithambiso ku-ophthalmology, noma njenge-excipient noma i-excipient emithini yomlomo.
Iyancibilika emanzini nakwezinye izincibilikisi, njenge-ethanol/amanzi, i-propanol/amanzi ngezilinganiso ezifanele.Isixazululo esinamanzi sinomsebenzi ongaphezulu.Ukucaca okuphezulu nokusebenza okuzinzile.Ukucaciswa okuhlukile kwemikhiqizo kunamazinga okushisa e-gel ahlukene kanye nezinguquko zokuncibilika nge-viscosity.I-viscosity ephansi, i-solubility enkulu.Ukucaciswa okuhlukile kwe-HPMC kunokusebenza okuhlukile.Ukuhlakazwa kwe-HPMC emanzini akuthintwa i-pH.

I-Hydroxypropyl Methyl Cellulose HPMC F60S Ye-Cement Based Tile Adhesive Mortar cps 400-200,000
IHydroxypropyl methylcellulose (HPMC) ayinaphunga, ayinambitheki, ayinabuthi i-cellulose ethers abe namaqembu e-hyrdroxyl ochungechungeni lwe-cellulose esikhundleni seqembu le-methoxy noma le-hydroxypropyl elinokuncibilika okuhle kwamanzi.I-HPMC F60S iyibanga le-viscosity ephezulu elisetshenziswa njenge-thickener, binder, kanye nefilimu yangaphambili kumakhemikhali ezolimo, okokuhlanganisa, izitsha zobumba, izinto zokunamathisela, oyinki, nezinye izinhlelo zokusebenza ezihlukahlukene.
