Yiziphi izinyathelo zokuphepha zokulinganisa i-viscosity ye-hydroxypropyl methyl celluloseI-HPMC? Lapho sihlola i-viscosity ye-cellulose. Ukuze kuqinisekiswe ukunemba kwemiphumela yokuhlolwa, ukunakwa okukhethekile kufanele kukhokhwe kulezi zici ezine ezilandelayo.
1. Izinkomba zokusebenza zethuluzi kufanele zihlangabezane nezimfuneko zemithetho kazwelonke yokuqinisekiswa kwe-metrological.
Ii-hydroxypropyl methyl celluloseIthuluzi lokulinganisa i-viscosity lisetshenziswa emjikelezweni wokuhlola. Uma kudingekile (ithuluzi livame ukusetshenziswa noma esimweni esibucayi sokufaneleka), ukuzihlola kwangaphakathi kuyenziwa ukuze kuqinisekiswe ukuthi ukusebenza kokulinganisa kuyafaneleka futhi iphutha le-coefficient lingaphakathi kwebanga elivumelekile, ngaphandle kwalokho idatha enembile ayikwazi ukutholwa.
2. Naka ngokukhethekile izinga lokushisa loketshezi olulinganiswayo.
Abasebenzisi abaningi bakuziba lokhu futhi bacabanga ukuthi izinga lokushisa cishe alibalulekile. Ukuhlola kwethu kubonisa ukuthi: uma ukuchezuka kwezinga lokushisa kungu-0.5℃, ukuchezuka kwe-viscosity kolunye uketshezi kungaphezu kuka-5%. Ukuchezuka kwezinga lokushisa kunomthelela omkhulu ku-viscosity, izinga lokushisa kanye ne-viscosity. Ngakho-ke, ukunakekelwa okukhethekile kufanele kuthathwe ukuze kugcinwe izinga lokushisa loketshezi olulinganisiwe eduze nendawo yokushisa eshiwo, futhi ukuze kulinganiswe okunembile, kungcono kakhulu ukuthi kungadluli ku-0.1℃.
3. Ukukhethwa kwesitsha sokulinganisa (ithubhu langaphandle).
Ukuze uthole ama-viscometers ajikelezayo anemiphongolo emibili, funda ibhukwana lensimbi ngokucophelela futhi ufanise i-rotor (isilinda sangaphakathi) ngokufanele. Isilinda sangaphandle, ngaphandle kwalokho imiphumela yokulinganisa izochezuka kakhulu. Ukuze uthole i-viscometer yokujikeleza kwe-cylinder eyodwa, i-radius yesilinda yangaphandle kufanele ingapheli ngokomthetho. Isilinganiso sangempela sidinga ukuthi ububanzi bangaphakathi besilinda bungabi ngaphansi kosayizi othile. Isibonelo, i-viscometer ye-rotary ye-NDJ-1 idinga i-beaker yokulinganisa noma isiqukathi seshubhu eliqondile elingekho ngaphansi kuka-70 mm ububanzi. Ukuhlola kubonise ukuthi amaphutha amakhulu okulinganisa angabangela uma ububanzi bangaphakathi bomkhumbi buncane kakhulu, ikakhulukazi uma i-rotor no. 1 isetshenziswa.
4, khetha kahle i-rotor noma ulungise isivinini, ukuze inani legridi yamandla libe phakathi kuka-20-90.
Lolu hlobo lwensimbi lusebenzisa ukufundwa kwesikhombi sokudayela kanye, futhi inhlanganisela yokuzinza nokuchezuka kokufunda kunamagridi angu-0.5. Uma ukufundwa kukuncane kakhulu, kusondela kumagridi angu-5, iphutha elihlobene lingaba ngaphezu kuka-10%. Uma i-rotor efanele ikhethiwe noma ukufundwa kwejubane kungu-50, iphutha elihlobene lingancishiswa libe ngu-1%. Uma inani libonisa ngaphezu kwe-90, i-torque ekhiqizwa entwasahlobo inkulu kakhulu, ejwayele ukukhasa futhi ilimaze i-hairspring, ngakho-ke kufanele sikhethe kahle i-rotor nesivinini.
Leli phepha lethula izindaba ezidinga ukunakwa ekukaleni i-viscosity ye-hydroxypropyl methyl cellulose, ngethemba lokuthi okuqukethwe okungenhla kungakusiza ukuthi uhlole.I-KIMA CHEMICALihambisana nesimiso "sokusungula izinto ezintsha, ikhasimende kuqala, ikhwalithi kuqala". Umqondo wokuthuthukiswa kwebhizinisi uwukwakha phezu kokwethenjwa nokuthuthukiswa kwesikhathi eside, ukusungula izinto ezintsha njalo nobuchwepheshe, ekuvikelweni kwemvelo okuluhlaza kanye nokuthuthukiswa kobuchwepheshe obuphezulu. Inkampani izimisele ukubambisana nemikhiqizo yasekhaya nezangaphandle okusezingeni eliphezulu nabangane isikhathi eside, ukubambisana okuqotho.
