Kev txhais qhov viscosity yog qhov tseem ceeb rau kev saib xyuas qhov zoo ntawm cov khoom ntau yam, piv txwv li cov roj petroleum thiab cov khoom siv polymer, thiab rau cov khoom siv pharma thiab cov khoom siv noj. Tiamsis, cov viscometers tsis muaj ob leeg uas zoo ib yam. Ob qhov tseem ceeb tshaj plaws yog: kinematic thiab dynamic (uas kuj hu ua absolute) viscometers. Txhais kom paub qhov sib txawv ntawm ob qhov no yog tseem ceeb rau koj los xaiv cov khoom siv uas xav tau rau koj cov kev siv, kom paub tias cov lus txhais uas tau txais yog zoo rau qhov chaw uas koj xav tau thiab kom paub tias nws tau txhais raws li cov kev cai ntawm lub nroog. Ntawd yog cov qhov sib txawv tseem ceeb.
1. Qhov txhais thiab cov kev txhais kev sib txawv
Cov tshuam kev ntsuas kev tiv thaiv ntawm cov dej thiab cov dej tshuaj rau kev npaj los ntawm qhov cuab yeej ntawm qhov chaw nyob, thiab txheeb xyuas kev ntsuas kev npaj los. Kev ntsuas kev npaj los ntawm cov dej thiab cov dej tshuaj yog qhov sib piv ntawm kev ntsuas kev npaj los thiab qhov ntau ntawm cov dej thiab cov dej tshuaj. Cov kev ntsuas kev npaj los uas sib npaj dua yog cov kev ntsuas uas muaj lub cua (piv txwv li Ubbelohde thiab Cannon Fenske) uas cov neeg ntsuas txheeb xyuas qhov teeb meem uas cov dej thiab cov dej tshuaj npaj los ntawm lub cua uas tau muab txheeb xyuas, thiab qhov teeb meem no yog muab txais rau hauv cov thawv centistokes (cSt) lossis mm²/s.
Cov kev ntsuas kev npaj los (uas tseem hu ua kev ntsuas kev npaj los tshwj xeeb) txheeb xyuas kev tiv thaiv ntawm cov dej thiab cov dej tshuaj rau kev npaj los thaum muaj qhov cuab yeej uas tsis yog qhov cuab yeej ntawm qhov chaw nyob. Lawv txheeb xyuas kev npaj los tshwj xeeb (uas tseem hu ua kev npaj los tshwj xeeb) raws li qhov txheeb xyuas kev tiv thaiv ntawm cov dej thiab cov dej tshuaj rau kev npaj los thaum muaj qhov cuab yeej uas muab tuaj rau, tsis txhawm rau qhov ntau ntawm lawv. Cov kev ntsuas uas sib npaj dua yog: cov kev ntsuas uas muaj kev rov qab, cov kev ntsuas uas muaj lub roj rov qab, thiab cov kev ntsuas uas muaj lub roj rov qab thiab cov kev ntsuas uas muaj lub roj rov qab, thiab cov lus txais yog muab txais rau hauv cov thawv centipoise (cP) lossis millipascalseconds (mPa·s).
2. Cov nts kev siv thiab cov kev kawm tseem ceeb
Cov viscometers kinematic yog qhov zoo tshaj plaws rau kev txheeb xyuam rau cov khoom tsis muaj kev cuam tshuam. Lawv yog cov dej uas tsis muaj kev cuam tshuam thaum muaj kev cuam tshuam. Cov kev siv tseem ceeb yog:
Cov khoom ntawm petroleum (txwv. Lubricating oils, fuels thiab bitumen)
Cov polymers thiab resins
Cov lus thiab cov khoom siv rau lub tsho
Cov dej ntawm qhov noj thiab cov syrup
Ntau yam standards ntawm lub ntiaj teb, txwv. ASTM D445, siv kev txheeb xyuam kinematic rau cov khoom ntawm petroleum. Cov viscometers automation ntawm Zhongwang uas siv rau kev txheeb xyuam kev cuam tshuam ntawm dej thiab polymers tau sib tw rau kev txheeb xyuam thiab muaj kev ua haujlwm zoo heev.
Cov viscometers dynamic yog qhov muaj txiaj ntsig rau kev txheeb xyuam rau cov dej Newtonian thiab non-Newtonian. Lawv pab rau:
Cov adhesive, sealants thiab printing inks
Cov pharmaceuticals (gels, creams, pastes)
Cov ntsiab (piv txwv li cov lotion thiab cov shampoo)
Polymer melts thiab cov solution
Cov khoom noj (piv txwv li cov ketchup, yoghurts, chocolate)
3. Cov khoom siv thiab cov khoom siv automation
Cov viscometer kinematic tshaj tshuaj yuav tseem cia cov neeg siv qhia kom paub tias cov khoom yuav tawm los ntawm cov mark thiab yuav tsum kho cov khoom siv los ntawm cov glassware rau txhua lub sijhawm. Cov khoom siv uas neeg siv yuav tsum ua ntau yam thiab yuav muaj kev pab tsis zoo los ntawm cov neeg siv. Cov viscometer kinematic uas tau muab tuaj los ntawm Zhongwang yog cov khoom siv automation uas siv cov optical sensor los xam cov sijhawm flow, thiab muaj cov constant temperature bath thiab cov computer system uas yuav qhia kom cov sijhawm rov qab thiab rov qab los ntawm lub computer. Qhov no yuav tshem cov kev pab tsis zoo thiab cov kev pab tsis zoo los ntawm cov neeg siv. Nws muaj ntau lub sijhawm los siv rau ntau yam khoom siv hauv ib lub sijhawm.
Cov ntsiab ntawm kev siv cov viscometers tshwj xeeb yog los ntawm cov khoom siv uas yuav siv hauv qhov txheeb xyuas rau cov khoom siv uas siv rov qab thiab muaj kev cuam tshuam ntawm kev siv lub zog rov qab, thiab muaj cov khoom siv uas tuaj yeem kho kom tsis hloov qhov cua ntawm cov khoom siv. Cov viscometers tshwj xeeb uas siv tau zoo heev tuaj yeem txheeb xyuas cov khoom siv rau ntau qhov siv lub zog rov qab, piv txwv li rau kev pom cov cuab yeej ntawm kev siv lub zog rov qab thiab kev siv lub zog rov qab rau kev tshem tawm. Cov khoom siv uas siv rau kev siv cov khoom siv thiab kev tswj qhov cua ntawm Zhongwang yog qhov txaus siab rau cov viscometers tshwj xeeb vim nws tuaj yeem tswj kev ua cov khoom siv.
