Ukusetyenziswa kwe-hydroxypropyl methylcellulose kubanzi kakhulu, kwaye kunento eninzi yokwenza kunye ne-viscosity yayo, kwaye i-viscosity efunekayo yokusetyenziswa kwe-hydroxypropyl methylcellulose nayo yahlukile, ngoko xa sisebenzisa iimveliso zayo Okokuqala, kufuneka sazi ukuba yintoni i-viscosity yayo. kunjalo, kodwa i-viscosity ye-hydroxypropyl methylcellulose ichatshazelwa zizinto ezininzi.Ukuba ugcino aluqapheli, lunokubangela ukuba i-viscosity yayo ingaphumeleli.Ke kwi-hydroxypropyl methylcellulose, Zeziphi izinto ezihambelana ne-viscosity yayo?Makhe ndinazise ngokufutshane.
Ngokubanzi, i-viscosity ye-hydroxypropyl methylcellulose iya kuchatshazelwa zezi zinto zilandelayo:
1. Iqondo eliphezulu le-polymerization ye-cellulose ether kunye nobukhulu be-molecular weight, iphezulu i-viscosity yesisombululo sayo samanzi;
2. Okukhona idosi ephezulu (okanye i-concentration) ye-cellulose ether, iphezulu i-viscosity yesisombululo sayo samanzi, kodwa kufuneka kuthathelwe ingqalelo ukukhetha idosi efanelekileyo xa uyisebenzisa, ukwenzela ukuba ingachaphazeli ukusebenza kodaka kunye nekhonkrithi ukuba idosi iphezulu kakhulu;
3. Njengamanzi amaninzi, i-viscosity yesisombululo se-ether ye-cellulose iya kuncipha ngokunyuka kweqondo lokushisa, kwaye iphezulu i-concentration ye-cellulose ether, impembelelo enkulu yeqondo lokushisa;
Ngokubanzi, xa silawula i-viscosity ye-hydroxypropyl methylcellulose, siqwalasela kula manqaku angasentla, ngoko ke kufuneka sijonge kwaye siyisebenzise amaxesha amaninzi xa sigcina i-hydroxypropyl methylcellulose.
