HPMC (HydroxyPropyl methylcellose) iPolymer yakajairika inoshandiswa mune yemishonga, chikafu uye maindasitiri ezvekudya. Iyo mheremalose inobviswa yakagadzirwa nemakemikari kugadzirisa zvakasikwa cellulose. Imwe yeiyo yakakosha zvivakwa zveHPMC ndeyevavhu yayo, iyo inoshanduka zvichienderana nezvinhu zvakasiyana-siyana sekupisa.
Viscosity chiyero chekurwisa kwemvura kana chezvemukati kuyerera. Kune HPMC Polymers, viscosity inguva yakakosha paramende inokanganisa mashandiro ezvekushandisa mune dzakasiyana siyana. Iyo viscosity yeHPMC inokanganiswa nezvinhu zvinoverengeka zvakadai senge zvinorema, degree rekutsiva, uye tembiricha.
Viscosity-tembiricha hukama hweHPMC polymers
HPMC Polymers inoratidzira hushamwari hukama pakati peviscosity uye tembiricha. Kazhinji, kuwedzera kwe tembiricha kunokonzeresa kuderera kweViscosity. Maitiro aya anogona kutsanangurwa na:
1. Tembiricha inokanganisa hydrogen kusungwa
MuHPMC polymers, intermolecular hydrogen zvisungo zvine mutoro wekugadzira yakasimba network network network. Iyi network network inobatsira kuwedzera iyo visikopa yezvinyorwa. Kuwedzera tembiricha kunokonzeresa iyo hydrogen zvishuwo kuputsa, nekudaro kuderedza iyo intermolecular yekukwezva mauto uye nekudaro ichidzora mavhoti. Zvinotenderana, kuderera kwekushisa kukonzera kuwanda kwehydrogen zvisungo kuumba, zvichikonzera kuwedzera kwe viscosity.
2. Tembiricha inokanganisa molecular yekufamba
Kumba dzakakwirira, mamorekuru mukati meHPMC Polymer zvacho zvimiro zvine simba reKinetic uye inogona kufamba zvakanyanya. Izvi zvakawedzera mafambiro anokanganisa chimiro chePolymer uye anoderedza zvavakaita.
3. Tembiricha inokanganisa solvent zvivakwa
Iyo viscosity yeHPMC Polymer Solutions inoenderana nemhando yeiyo solvent. Mamwe masosi, akadai semvura, ratidza kuderera kweViscosity sezvo tembiricha inowedzera nekuda kwekushayikwa kwehydrogen zvisungo zveHydrogen. Mukupesana, mamwe mashiromita anoratidzira yakawedzera zvevisiko munzvimbo dzakakwirira dzekupisa, dzakadai se glycerol.
Izvo zvakakosha kucherechedza kuti ndizvo zvakajeka zvehukama hwekupisa-viscosity Semuenzaniso, mamwe magiredhi eHPMC anoratidza kutsamira kwakasimba kwakasimba, nepo vamwe vakagadzikana. Zvakare, iyo visikopa yeHPMC inowedzera sekuwedzera kwekuwedzera kunowedzera, uye hukama pakati pekudziya neViscosity shanduko zvakare.
Kukosha kweViscosity muHPMC application
Muindasitiri yemishonga, HPMC ishandirwi inowanzoitwa polymer mune zvinodhaka zvekushandisa zvinodhaka, uko chaiko kudzora kwekushandiswa kwezvinodhaka uye maitiro anodiwa. Viscosity inotora basa rakakosha mukusunungurwa kwezvinodhaka sekukanganisa kwezvinodhaka kuburikidza nePolymer Matrix. Uye zvakare, iyo viscosity yeHPMC yakakoshawo mukubatanidza mafomu, sezvo yakakwirira viscosity inodiwa kuti ive nechokwadi chekuvimbisa yunifomu uye inoenderera ichivharira.
Zvigadzirwa zvekudya zvinoshandisa HPMC semumiriri uye emulsifier inoda chaiyo viscosity kukosha kuti ive nechokwadi chekuti chigadzirwa chinoramba chichiiswa uye panguva yekugadzirisa. Saizvozvo
HPMC inzvimbo inoverengeka inoverengeka inoratidzira hukama husiri hweplitline pakati pevisikoka uye tembiricha. Kuwedzera tembiricha kunoguma nekudzikira muViscosity, kunyanya nekuda kwemhedzisiro yekupisa pane intermolecular hydrogen kusungwa, molecular kufamba, uye solvent zvivakwa. Kunzwisisa hukama hwekupisa Naizvozvo, kudzidza kweHPMC viscosity kwakakosha kuti uve nechokwadi chekureva kwekunyepedzera mune dzakasiyana-siyana zvibodzwa mumishonga yemishonga, chikafu uye cosmetic.
