Ubbelohde viscometers, uas pab tshuaj xyuam qhov ntev ntawm lub zis (qhov chaw uas muaj kev sib piv rau viscosity), yog ib qho ntawm cov khoom siv tseem ceeb no. Viscosity yog qhov sib piv rau qhov yuav li cas lub zis yuav dhau los ntawm qhov twj ywm. Piv txwv li, honey yog ntev thiab yuav dhau los yuav tshaub, tab sis dej yog tsis ntev thiab yuav dhau los yuav nyuaj. Ib qho Ubbelohde viscometer yog qhov tseem ceeb rau ntau qhov kev lag luam, los ntawm kev lag luam noj mov mus rau kev lag luam kho mob thiab kev lag luam cheeb tsam. Cov thawj coj xav tau kev xyuam tshuaj tshiab tshaj plaws thaum lawv xav paub qhov yuav li cas lub zis yuav ua haujlwm. Ntawd yog qhov uas cov viscosimeter Ubbelohde paub tshaj plaws. Lawv yog qhov tseem ceeb rau lawv kev tshuaj xyuam tshiab, uas pab cov thawj coj tsim cov khoom zoo dua. Ntawm ZONWON no, peb paub tias qhov tseem ceeb ntawm kev xyuam tshuaj qhov cua sov yog qhov tseem ceeb heev.
9. Cov Qhov Siv Tswv Yim ntawm Cov Ntawv Viscosity Intrinsic rau cov Tshuab Tshuab
Hauv cov thawv sib tshuam, cov tuam tshab muab cov khoom ntau dua kom tau txais kev siv tom ntej. Ib qho khoom siv uas cov tuam tshab siv dav rau hauv no yog intrinsic viscosity meter. Cov meter uas siv lub cev no yuav pab kuaj qhov ntev ntawm daim duab thiab qhov ...
