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.

Ntawd li cas, peb muaj kev pab tus neeg siv khoom zoo heev uas tsis tau txhais kom pom. Yog tias koj muaj lwm yam nug lossis koj xav tau kev pab los xaiv lub viscometer uas zoo rau koj siv, thov koj hu rau peb thaum twg kuj tau. Peb qhov tiam ntawv yog kom qhov kev siv khoom yog qhov yooj yim thiab yooj yim rau koj. Yog tias koj nug peb, qhov khoom uas zoo rau koj tsis yooj yim los nrhiav. Qhov no yog peb txhais tau tias peb xav tau sib sib raug rau cov neeg siv khoom.
Yog qhov tseem ceeb ntawm lub oil rau lub cev yog nws qhov viscosity, uas yuav tsum yog ib qho zoo heev rau lub oil los ua haujlwm zoo rau hauv lub cev. Yog tias lub oil yog loj heev, nws tsis tuaj yeem hlub zoo; yog tias nws yog nyoo heev, nws tsis tuaj yeem pab saib xyuam lub cev zoo dua. ZONWON yog ib qho piv txwv ntawm ib qho kompam thiab uas muaj kev xaiv lub oil rau lub cev zoo los ntawm kev siv lub viscometer Ubbelohde, uas tom qab ntawd pab cov roj plaub ntawm lawv mus ua haujlwm zoo thiab safety.
Lub viscometer Ubbelohde muaj ntau qhov tseem ceeb dua li lwm qhov viscometer. Ib qho tseem ceeb tshaj plaws ntawm Ubbelohde hom viscometer yog tias lawv tuaj yeem muab cov lus nug tshwj xeeb. Thaum kawm txog kev ua haujlwm ntawm cov dej, nws yog qhov tseem ceeb kom tau cov lus nug tshwj xeeb, thiab cov viscometers Ubbelohde ua qhov no los ntawm kom muab cov lus nug tshwj xeeb. Qhov no yog tshwj xeeb heev rau cov qhov chaw uas tsuas yog qhov puas tsuas yooj yim tuaj yeem pab cuam tshuam rau qhov teeb meem loj. Piv txwv li, qhov viscosity tshwj xeeb ntawm cov dej rau kev kho mob yog qhov tseem ceeb rau qhov kev kho mob kom muaj kev nyab xeeb rau cov neeg siv. Cov viscometers Ubbelohde tuaj yeem siv los kawm kom paub tias cov lus kho mob no yog nyab xeeb thiab muaj kev ua haujlwm.
Cov viscometers Ubbelohde kuj yog qhov muaj kev sib thag ntau tshaj plaws. Lawv kuj tuaj yeem siv los kawm qhov viscosity ntawm cov dej piv li: cov lus npav, cov dej lub, thiab cov lus siv rau qhov noj. Txhua yam, qhov kev sib thag no yog qhov ua rau cov khoom no muaj kev sib thag rau ntau qhov chaw. Nrog rau ib qhov khoom, koj tuaj yeem kawm cov khoom ntau yam thiab qhov no tsis yog qhov tseem ceeb rau cov viscometers lwm yam. Qhov no yuav muaj kev pab heev thiab yuav sau qhov chaw rau koj lub tsev kho mob lossis lub tsev ua haujlwm.
