Lub Mooney viscometer yog ib qho cuab yeej siv dav hauv kev sim roj hmab thiab cov khoom siv polymer, tsim los ntsuas tus cwj pwm viscoelastic thiab kev ua haujlwm ntawm cov roj hmab hauv qab tswj cov cua sov. Los ntawm kev ntsuam xyuas qhov tsis kam ntawm cov khoom rau kev sib hloov lossis oscillation ntawm qhov kub thiab txias, viscometer muab cov ntaub ntawv tseem ceeb ntawm qhov pib viscosity, processability, thiab vulcanization kev ua, txhawb kev tsim kho kom zoo thiab kev tswj xyuas ntau lawm.
Lub hauv paus ntsiab lus ua haujlwm yog ua raws li kev ntsuas torque. Lub ntsiab tivthaiv yog ib tug rotating los yog oscillating rotor muab tso rau hauv ib tug rhuab qauv chamber. Thaum cov qauv roj hmab softens nyob rau hauv qhov kub thiab txias, lub rotor pib tig los yog oscillate, thiab cov khoom exerts tiv thaiv lub rotor. Qhov kev tiv thaiv no yog ntsuas tsis tu ncua los ntawm lub zog torque thiab hloov mus rau Mooney viscosity qhov tseem ceeb.
Kev tswj qhov kub thiab txias kom ntseeg tau tias cov qauv sib xyaw ua kom sov thiab khaws cia ntawm qhov kub thiab txias, lav qhov ua tau zoo dua. Raws li qhov kev sim nce mus, viscosity ntawm cov khoom hloov pauv. Piv txwv li, thaum lub sij hawm pib ntawm vulcanization, cov kuj maj mam nce. Kev sau cov kev tiv thaiv lub sijhawm tso cai rau kev txiav txim siab ntawm qhov tseem ceeb xws li thawj viscosity, yam tsawg kawg nkaus viscosity, siab tshaj plaws viscosity, thiab vulcanization kev ua.
Niaj hnub nimno Mooney viscometers tau nruab nrog cov lus qhia digital thiab cov ntaub ntawv kaw lus, ua kom pom tseeb tiag - lub sijhawm pom ntawm viscosity qhov tseem ceeb thiab nkhaus kom yooj yim txheeb xyuas. Cov qauv Advanced kuj tseem tuaj yeem suav Mooney indices, vulcanization tus nqi, thiab lwm yam tsis tseem ceeb, txhim kho kev ntsuas kev ua tau zoo thiab raug.
Zuag qhia tag nrho, Mooney viscometer quantitatively soj ntsuam cov roj hmab ua kev ua tau zoo thiab cov yam ntxwv vulcanization los ntawm kev ntsuas qhov tsis kam ntawm cov roj hmab softened rau rotor txav. Nws kev sib xyaw ua ke ntawm kev ntsuas qhov tseeb torque thiab kev tswj qhov kub thiab txias ua rau nws yog ib qho cuab yeej tseem ceeb hauv kev tsim cov roj hmab tsim thiab kev tswj kom zoo.
