Reka tuvuge kuri hydroxypropyl methyl selulose HPMC nuburyo bwo gupima ububobere bwayo.Ubukonje hano bwerekana ububobere bugaragara, ni ikintu cyingenzi kuri hydroxypropyl methyl selulose.
Bisanzwe.Uburyo busanzwe bwo gupima ni ugupima ibizunguruka byuzuzanya, gupima capillary viscosity gupima no gupima ububobere bwo kugwa.Uburyo bwo kugena hydroxypropyl methyl selulose yari capillary adhesion.
Uburyo bwo kumenya impamyabumenyi, ukoresheje Uchs viscometer.Mubisanzwe kugena igisubizo ni 2% igisubizo cyamazi, formula ni: V = Kdt.V nubukonje muri mpa.s na K ni viscometer ihoraho.
D nubucucike bwubushyuhe buhoraho na T nigihe cyo kuva hejuru kugeza hasi unyuze kuri viscometero mumasegonda.Ubu buryo bwo gukora buraruhije, niba hari ikibazo kidakemuka.
Amagambo aroroshye gutera amakosa, biragoye kumenya ubwiza bwa hydroxypropyl methyl selulose.Ubu irakoreshwa mugupima ubwiza bwa rotc viscometer, ikoreshwa muri rusange mubushinwa.
Inzira ya viscometer ya NDJ-1 ni η = Kα.η ni viscosity, no muri mpa.s, K ni coefficient ya viscometer, na α ni ugusoma icyerekezo cya viscometer.
Hydroxypropyl methyl selulose 2% uburyo bwo gupima viscosity:
1, ubu buryo burakwiriye kugirango hamenyekane imbaraga zijimye zidafite amazi ya Newtonian (igisubizo cya polymer, guhagarika, gukwirakwiza amavuta ya emulsiya cyangwa igisubizo kiboneka, nibindi).
2. Ibikoresho n'ibikoresho
2.1 Rotc viscometer (NdJ-1 na NDJ-4 zisabwa na Pharmacopoeia yo mu Bushinwa)
2.2 Ubushyuhe burigihe amazi yo kwiyuhagira guhorana ubushyuhe 0.10C
2.3 Impamyabumenyi yo gutanga amanota ni 0,20C, igenzurwa buri gihe.
2.4 Imetero yumurongo Viscometero ukoresheje ingamba zo guhagarika imirongo (nka NDJ-1 na NDJ-4) igomba kubikwa.Ukuri kwa 1%.A.
8. Icyitegererezo cya Og cyapimwe neza hanyuma gishyirwa mu cyuma cyumye, gifite toni 400mL.Ongeramo hafi 100mL ya dogere 80-90 y'amazi ashyushye hanyuma ukangure 10min kugirango utandukanye
Kwirakwiza neza, koga no kongeramo amazi akonje kuri 400mL yose hamwe.Hagati aho, koga ubudahwema 30min kugirango ukemure 2% (W / W), hanyuma ubishyire muri firigo kugirango woge urubura kugirango ukonje kugeza bibaye urubura ruto hejuru.
Kuramo hanyuma ushyire mubigega bihoraho byubushyuhe kugirango ubushyuhe bwo hagati bugere kuri 20 ℃ 0.1 ℃.
3.1 Kwishyiriraho no gukoresha igikoresho bizakorwa hubahirijwe amabwiriza yimikorere yicyo gikoresho, kandi rotor na rotor ikwiye bizatoranywa hakurikijwe ubwiza bwibicuruzwa byageragejwe hamwe nibiteganijwe muri farumasi nkuko byanditswe ibicuruzwa
Umuvuduko wo kuzunguruka.
3.2 Hindura ubushyuhe bwamazi yubushyuhe burigihe ukurikije icyemezo kiri muri buri kintu cyibiyobyabwenge.
3.3 Igicuruzwa cyapimwe cyashyizwe mubikoresho byagenwe nigikoresho, hanyuma Inguni (a) ihindagurika yapimwe hakurikijwe amategeko nyuma yiminota 30 yubushyuhe buhoraho.Zimya moteri hanyuma utangire kugirango wiyemeze ubundi
Itandukaniro riri hagati yagaciro ntirishobora kurenga 3%, naho ubundi hagomba gukorwa igipimo cya gatatu.
3.4 Kubara agaciro kagereranijwe mubizamini byombi ukurikije formulaire kugirango ubone imbaraga za viscosity yibicuruzwa byapimwe.
4. Andika kandi ubare
4.1 Andika icyitegererezo cya viscometer yerekana, umubare wa rotor n'umuvuduko ukoreshwa, viscometer ihoraho (K 'agaciro), ubushyuhe bwapimwe, na buri gipimo.Agaciro.
Inzira yo kubara ya 4.2
Dynamic viscosity (MPa ”s) = Ka aho K ni viscometer ihora ipimwa hamwe namazi asanzwe yubusembwa buzwi na A nuburyo bwo gutandukana
