Kwv txhiaj cov viscometer kinematic yog qhov tseem ceeb rau lub tsev kho mob petroleum, polymer, chemical lossis pharmaceutical. Cov khoom uas tau xaiv zoo yuav pab ua kom muaj kev ua tau zoo, ua kom tau ntau dua, thiab ua kom ntau dua. Cov khoom uas tsis tau xaiv zoo yuav pab ua kom muaj kev ua tau tsis zoo, tsis muaj kev ua tau zoo, yuav tsum ua dua, thiab cov neeg ua haujlwm nyob rau hauv lub tsev kho mob yuav nyuaj siab. Rau kom pab koj xaiv cov viscometer kinematic zoo tshaj plaws rau koj lub tsev kho mob, no yog cov ntaub ntawv tseem ceeb uas koj yuav tsum xyuam xyuam.
1. Keem ntsuas qhov cim ntawm qhov cim
Cov viscosity yog qhov tseem ceeb uas muaj kev sib koom nrog qhov cim. Rau cov lubricants thiab cov polymer solutions ntau yam, qhov cim yuav ncua ntau dua 0.5 °C yuav pab ua kom muaj kev ntxiv ntau dua ntau dua, thiab tsis tuaj yeem ua kom muaj kev paub txog cov khoom. Vim li no, keem ntsuas qhov cim yog qhov tseem ceeb rau kev xaiv cov viscometer kinematic.
Koj yuav xav nrhiav lub khoom uas muaj qhov paub ua kom txhawj tshuaj cov cim ntawm lub tshuab hauv ±0.01°C rau ±0.02°C ntawm cov cim uas koj xav tau thaum muaj kev siv hauv qhov hluav taws xob tag nrho. Qhov no feem ntau txhais tias lub tshuab yuav tsum muaj lub system kawg siab uas pab kom tsis muaj kev cuam tshuam ntawm cov cim txhawj tshuaj hauv lub tshuab tag nrho. Thaum kawg, lub viscometer yuav muaj lub PRT (platinum resistance thermometer) nyob hauv thiab yuav tsum muaj lub PRT ntaus rau hauv kom ua haujlwm zoo thiab kom muaj kev kho tshuaj tshwj xeeb. Yog koj yuav ua kev vam tshuaj kev ntsuas viscosity rau ntau yam khoom sib txawv, koj tuaj yeem xav ua lub khoom uas muaj qhov paub ua kev ntsuas cov cim txhawj tshuaj los ua kev ntsuas viscosity rau ntau yam cim txhawj tshuaj tsis tas yuav muaj tus neeg siv kho. Hangzhou Zhongwang Technology tuaj yeem tsim lub viscometer uas muaj lub tshuab kom muaj kev nyab xeeb uas tuaj yeem siv rau ASTM D445 thiab ISO 3104.
2. Kev ntsuas lub sijhawm flow uas ua kom tshwj xeeb
Kev ntsuas lub cim ntawm cov dej uas nyob rau hauv lub tshuab ntsuas viscosity thiab siv lub stopwatch yog qhov kev cuam tshuam ib yam rau kev ntsuas kinematic viscosity. Qhov cuam tshuam ntawm kev txhawj xeeb ntawm tus neeg tuaj yeem ua rau tsis tuaj yeem ntsuas tau raws li qhov tseem ceeb, thiab rau cov dej uas muaj li cas los sis, nws yuav tsis tuaj yeem pom tau qhov cim ntawm cov dej uas nyob rau hauv lub tshuab.
Koj yuav tsum xaiv lub tshuab ntsuas uas tuaj yeem pom lub cim ntawm cov dej uas nyob rau hauv lub tshuab raws li qhov tseem ceeb. Nws feem ntau siv cov sensor optical lossis cov sensor thermal kom pom tau qhov cim ntawm cov dej uas nyob rau hauv lub tshuab thaum nws tau txog ob qhov cim tseem ceeb rau hauv lub tshuab. Lub cim ntawm kev txhawj xeeb yog ntsuas tau raws li qhov tseem ceeb, thiab tsis muaj kev cuam tshuam ntawm tus neeg. Qhov kev pom tau raws li qhov tseem ceeb no yuav pab tau ntau rau kev ntsuas tau raws li qhov tseem ceeb, thiab pab tau lub tshuab ntsuas tuaj yeem ua haujlwm tsis muaj neeg saib xyuam. Rau cov laboratori uas ntsuas ntau yam dej hauv ib hnub, qhov kev ua haujlwm no yuav pab tau ntau rau kev ntsuas tau ntau dua.
3. Qhov kev saib xyuam thiab qhov kev kho cov dej uas nyob rau hauv lub tshuab
Ku qhia cov khoom siv rau kev ua haujlwm ntawm kev ua kom zoo thiab yuav tsum ua ntau yam haujlwm, thiab nws yuav tsum ua raws li qhov tseem ceeb. Raws li qhov kev sib piv, cov neeg siv khoom yuav tsum npaj lub tshuab, saum nws los ntawm cov khoom siv uas yuav tsum ua kom zoo, txhawj cov khoom siv uas yuav tsum ua kom zoo, suav nws los ntawm cov khoom siv uas yuav tsum ua kom zoo los ntawm cov khoom siv uas yuav tsum ua kom zoo, thiab thaum kawg yuav tsum ua kom paub tias lub tshuab tau ua kom zoo lawm. Cov haujlwm no txhua yam pheej ua tau ib yam li qhov kev ua haujlwm.
Koj yuav xav nrhiav lub viscometer kinematic uas muaj lub tshuab saib xyuam kom ua tau los ntawm kev pab. Thaum kawm qhov viscosity raws li txog, lub viscometer yuav npaj lub capillary nrog ib los yog ob daim solvent thiab txhawj lawv, tom qab ntawd yuav txhawj cov hauv qab los yog cov hauv qab tsis muaj oxygen los ntawm lub capillary kom txhawj tau zoo heev. Cov tshuab saib xyuam no yuav raug sau rau hauv lub tshuab kom ua tau los ntawm kev pab, thiab yuav sib dhos heev rau tag nrho cov tshuab ua tau los ntawm kev pab, kom txhawj qhov teeb meem ntawm kev ua tau los ntawm kev pab tau 70–80%. Lawv kuj paub tias tsis muaj kev tshuab tshuab los ntawm kev saib xyuam tsis zoo. Ib qho lub tshuab kuj muaj qhov paub kom txhawj cov solvent saib xyuam kom ua dua.
4. Kev pab cov cim thiab kev sib koom
Nyob rau hauv cov laboratori tshiab, kev siv cov khoom siv automation kuj muaj kev siv rau kev paub cov lus qhia thiab, ua rau cov khoom siv tsis xav siv lub tshuab ntawv yog qhov zoo tshaj plaws. Cov khoom siv uas tsis tuaj yeem sib txuas nrog koj LIMS (laboratory information management system) yuav tsis tuaj yeem sib txuas cov lus qhia thiab yuav tsum sau cov lus qhia los ntawm lub tshuab ntawv rau hauv cov khoom siv kom muaj kev ploj kev ua haujlwm.
Cov ntsiab ntawm cov khoom siv no yuav tsum muaj qhov khoob cim txhais lus thiab yuav tsum muaj kev sib kis rau koj lub network kom muaj kev sib kis rau koj lub LIMS. Thaum xaiv cov khoom siv uas zoo rau koj, koj yuav tsum paub tias txhua qhov tswv yim uas tseem ceeb (lub npe ntawm cov lus, lub hmoov ntawm cov lus, lub sijhawm ntawm cov lus, qhov tswv yim ntawm cov lus, lub sijhawm thiab hnub ntawm cov lus thiab tus neeg siv) yuav tsum cim rau hauv cov lus. Yog koj lub tsev kho mob tau txais kom ua raws li GLP/GMP lossis cov system quality ntawm ISO xws li IATF 16949 lossis ISO 9001, ces cov feem ua haujlwm ntawm audit trail yuav tsum muaj los txhawj kom cov lus tsis muaj kev puas tsuaj. Qee yam khoom siv tuaj yeem muaj kev sib kis los ntawm qhov kev sib kis rau hauv qhov kev sib kis thiab kev siv cov lus.
Cov hais txog
Cov laus qhia ntawm kev siv lub tshuab kawm txog kev hloov (kinematic viscometer) uas yuav tsum muaj yog: kev saib xyuam ntau thiab tsis tu ncua, kev tswb lub sijhawm uas cov dej hloov, kev saib xyuam thiab kev hlau cov khoom uas tau siv, thiab kev saib xyuam cov lus qhia thiab kev sib tw. Cov qhia no yuav pab rau kev ua kom zoo dua, ua tau ntau dua, ua kom tsis txaus siab thiab paub tias koj tau ua raws li cov kev ceev ntau uas xav tau rau koj lub tsev kho mob. Hangzhou Zhongwang Technology Co., Ltd yuav pab ua thiab xa cov tshuab kawm txog kev hloov uas muaj kev sib tw thiab kev saib xyuam rau cov dej thiab cov khoom uas muaj kev hloov, thiab cov khoom uas pab kev ua haujlwm, los ntawm cov tuba uas muaj kev hloov thiab cov khoom uas yuav tsum siv, cov tshuab ua kom dej ntws thiab cov tshuab ua kom dej cuag, cov tshuab ua kom dej txias, cov tshuab ua kom dej ntws, thiab cov tshuab ua kom dej txias. Thov hu rau Hangzhou Zhongwang Technology tam sim no thiab ib tug nyias uas yuav pab koj nrhiav tus tshuab kawm txog kev hloov uas zoo tshaj plaws rau koj lub tsev kho mob.
