Ukusetshenziswa kwe-hydroxypropyl methylcellulose kubanzi kakhulu, futhi kuhlobene kakhulu ne-viscosity yayo, futhi i-viscosity edingekayo ekusetshenzisweni okuhlukile kwe-hydroxypropyl methylcellulose nayo ihlukile, ngakho-ke uma sisebenzisa imikhiqizo yayo Okokuqala, kufanele sazi ukuthi i-viscosity yayo ingakanani. kodwa i-viscosity ye-hydroxypropyl methylcellulose ithintwa izici eziningi.Uma isitoreji singanakile, singabangela ukuba i-viscosity yayo ihluleke.Ngakho-ke nge-hydroxypropyl methylcellulose, Yiziphi izici i-viscosity yayo ehlobene nazo?Ake ngikwethule kafushane.
Ngokuvamile, i-viscosity ye-hydroxypropyl methylcellulose izothinteka yizici ezilandelayo:
1. Izinga eliphakeme le-polymerization ye-cellulose ether kanye nesisindo se-molecular sikhulu, ukuphakama kwe-viscosity yesisombululo sayo esinamanzi;
2. Uma uphakeme umthamo (noma ukugxila) kwe-cellulose ether, kulapho i-viscosity yesisombululo sayo esinamanzi iphezulu, kodwa kufanele kuthathwe ukunakekelwa ukuze kukhethwe umthamo ofanele uma uyisebenzisa, ukuze ungaphazamisi ukusebenza kodaka nokhonkolo uma umthamo uphezulu kakhulu;
3. Njengoketshezi oluningi, i-viscosity yesisombululo se-cellulose ether izokwehla ngokunyuka kwezinga lokushisa, futhi ukuphakama kwe-cellulose ether, ithonya elikhulu lokushisa;
Ngokuvamile, lapho silawula i-viscosity ye-hydroxypropyl methylcellulose, sibheka kulawa maphuzu angenhla, ngakho-ke kufanele siyihlole futhi siyisebenzise izikhathi eziningi lapho sigcina i-hydroxypropyl methylcellulose.
