Hydroxypropyl methylcellulose (HPMC)ipolymer inoshandiswa zvakasiyana-siyana inoshandiswa mumaindasitiri akadai semishonga, kuvaka, zvizorwa, chikafu, uye kutarisira munhu. Iyo viscosity yeHPMC inoita basa rakakosha mukuona kukodzera kwayo kune akasiyana maapplication. Iyo viscosity inopesvedzerwa nehuremu hwemamorekuru, dhigirii rekutsiva, uye kuisa pfungwa. Kunzwisisa akakodzera viscosity mamakisi kwakakosha pakusarudza iyo chaiyo HPMC kune chaiyo maindasitiri zvinodiwa.
Viscosity Measurement
Iyo viscosity yeAnxinCel®HPMC inowanzoyerwa mumhinduro dzine mvura uchishandisa inotenderera kana capillary viscometer. Muyero wekushisa we20 ° C, uye viscosity inoratidzwa mumillipascal-seconds (mPa · s kana cP, centipoise). Akasiyana mamakisi eHPMC ane maviscosities akasiyana zvichienderana neavanoda kushandisa.
Viscosity Magiredhi uye Mashandisirwo Avo
Tafura iri pazasi inotsanangura akajairwa viscosity mamakisi eHPMC uye anoenderana mashandisirwo awo:
| Viscosity Giredhi (mPa·s) | Mafungiro Akajairika (%) | Application |
| 5 – 100 | 2 | Madonhwe eziso, zvokudya zvinowedzera, kumiswa |
| 100 - 400 | 2 | Mahwendefa ehuputi, mabhainda, zvinonamira |
| 400 - 1,500 | 2 | Emulsifiers, mafuta ekuzora, masisitimu ekutumira zvinodhaka |
| 1,500 - 4,000 | 2 | Kukobvura maajenti, zvigadzirwa zvekuchengeta munhu |
| 4,000 - 15,000 | 2 | Kuvaka (mataira anonamira, simende-yakavakirwa zvigadzirwa) |
| 15,000 - 75,000 | 2 | Kudzora-kuburitsa zvinodhaka kugadzirwa, kuvaka grouts |
| 75,000 - 200,000 | 2 | High-viscosity adhesives, simenti kusimbisa |
Zvinhu Zvinokanganisa Viscosity
Zvinhu zvinoverengeka zvinopesvedzera viscosity yeHPMC:
Molecular Weight:Yakakwirira molecular uremu kunotungamirira kuwedzera viscosity.
Dhigirii reKutsiva:Chiyero che hydroxypropyl uye methyl mapoka anokanganisa solubility uye viscosity.
Solution Concentration:Kuwedzera kwepamusoro kunokonzera viscosity yakakura.
Tembiricha:Viscosity inoderera nekuwedzera tembiricha.
pH Sensitivity:HPMC mhinduro dzakagadzikana mukati me pH renji ye3-11 asi inogona kudzikisira kunze kweiyo renji.
Shear Rate:HPMC inoratidza isiri-Newtonian kuyerera zvivakwa, zvichireva kuti viscosity inodzikira pasi pekunetseka kwekugera.
Mashandisirwo-Chaicho Kufunga
Pharmaceuticals:HPMC inoshandiswa mukugadzira mishonga yekudzora kuburitswa uye sebhainda mumapiritsi. Lower viscosity mamakisi (100–400 mPa·s) anosarudzwa pakupfekedza, nepo magiredhi epamusoro (15,000+ mPa·s) achishandiswa pakugadzirisa-kuburitswa.
Kuvaka:AnxinCel®HPMC inoshanda sechinhu chinochengeta mvura uye chinonamira muzvigadzirwa zvine simende. High-viscosity mamakisi (pamusoro pe4,000 mPa·s) akanakira kuvandudza kushanda uye kusimba kwekubatana.
Zvekuzora uye Kuchengeta Pamunhu:Mune shampoos, lotions, uye makirimu, HPMC inoshanda seyakakora uye inodzikamisa. Medium viscosity mamakisi (400–1,500 mPa·s) inopa mwero wakakwana pakati pemagadzirirwo uye kuyerera zvivakwa.
Indasitiri yeChikafu:Sekuwedzera kwechikafu (E464), HPMC inosimudzira magadzirirwo, kugadzikana, uye kuchengetedza mwando. Lower viscosity mamakisi (5–100 mPa·s) inovimbisa kupararira kwakakodzera pasina kukora zvakanyanya.
Kusarudzwa kweHPMCgiredhi re viscosity rinoenderana neyakarongedzerwa kunyorera, ine yakaderera viscosity mamakisi akakodzera mhinduro dzinoda kushoma kukora uye epamusoro viscosity mamakisi anoshandiswa mumigadziriso inoda yakasimba inonamira uye inodzikamisa zvivakwa. Yakafanira viscosity control inovimbisa kushanda kwakanaka mumishonga yemishonga, kuvaka, chikafu, uye maindasitiri ezvekuzora. Kunzwisisa zvinhu zvinopesvedzera viscosity kunobatsira mukugadzirisa kushandiswa kweHPMC kune akasiyana maindasitiri ekushandisa.
