Tej zaum koj yuav xav kom khov lub roj teeb rau -40℃ua ntej qhov ntsuas txias crank. Los yog koj yuav xav khiav lub voj voog av ntawm +85℃nrog 95 %
RH los xyuas seb lub rooj tsav xwm Circuit Court corrodes. Cov chav puv loj tuaj yeem ua qhov no, tab sis lawv nqa ib nrab ntawm chav tsev, suab zoo li lub tsheb tub yees, thiab yuam kom koj taug kev rov qab peb zaug ib zaug. Nws puas yuav zoo dua yog tias lub thawv me me, nyob ntsiag to ntawm koj lub rooj zaum tuaj yeem cuam tshuam cov huab cua kub zoo ib yam -thiab ua sai dua?
Ib tus neeg siv khoom hauv Ukrainian lab tsis ntev los no tau sau rau peb tus thawj tswj haujlwm Alice: "Nyob zoo Alice, ua tsaug rau koj tus email. Yog lawm, installation tiav lawm. Nws ua haujlwm zoo." Cov lus luv luv ntawd tuaj tom qab lawv tau txais lawv LIB TH-80 Mini Sub-Zero Chamber. Tsis muaj kev daws teeb meem hu. Tsis muaj kev cob qhia ntev. Tsuas yog ib chav ua haujlwm uas dhau lawv thawj pawg ntawm kev ntsuas txias-soak yam tsis muaj kev ua yeeb yam. Qhov ntawd yog hom kev ntseeg siab nyob ntsiag to peb cov chav tsim-vim thaum lub cuab yeej khiav ntawm -60℃rau plaub teev ncaj thiab tuav qhov kub ntawm ± 0.5 degree, tsuas yog tsis muaj dab tsi los yws txog.
Tsab ntawv xov xwm no qhia koj txog qhov kub thiab txias npaum li cas ntawm lub tshuab hluav taws xob me me tuaj yeem xa tuaj, uas yog cov qauv hauv ntiaj teb uas nws ua tau raws li, LIB lub kaw lus ua haujlwm li cas, ua tiav cov txheej txheem ua tiav raws li tus qauv Lavxias, thiab cov lus teb rau cov lus nug nquag txog kev xa khoom thiab kev txhawb nqa.
Qhov ntsuas kub dab tsi tuaj yeem ua rau Mini Sub-Zero Chamber Ua tiav?
Mini sub-zero chamber tsis yog khoom ua si. Nws yog ib lub chaw soj ntsuam-qib ib puag ncig uas haum rau ntawm lub rooj zaum tab sis tseem muaj qhov kub thiab txias txaus kom khov cov khoom siv hluav taws xob thiab siab txaus los ua cov nplaum nplaum.
1. Tsawg-Tsuas Muaj Peev Xwm: qis rau -86 degree
LIB's benchtop qauv ncav cuag tsawg li-86 degree(tsawg-hom D configuration). Qhov ntawd nyob deb dua tus qauv hauv lub freezers (-18 degree) lossis txawm tias muaj chaw txias txias (-40 degree). Ntawm -86 degree, feem ntau cov roj teeb lithium-ion poob ntau dua 80% ntawm lawv lub zog cranking, LCD cov ntxaij vab tshaus tig dub, thiab cov roj hmab ntsaws ruaj ruaj ua nkig li iav.
2. Muaj Peev Xwm Kub Kub: Txog li +150 degree
Tib chamber heats li+150 degreetsis xav tau lub qhov cub cais. Qhov no suav nrog cov kev sim solder yaj (feem ntau yog +138℃rau +150℃rau cov uas tsis kub kub) thiab ua kom cov kev tshawb fawb txog kev laus uas txhua +10℃roughly doubles cov tshuaj tiv thaiv.
3. Cov av noo: 20% txog 98% RH
Ntau lub mini sub-zero chambers kuj tswj cov av noo. LIB cov chav tswj hwm 20% mus rau 98% txheeb ze av noo nrog qhov sib txawv hauv qab ± 2.5% RH. Qhov ntawd txhais tau hais tias koj tuaj yeem sim ua cov suab puam qhuav thaum sawv ntxov (20 % RH) ntawm +40 degree, tom qab ntawd hloov mus rau huab cua sov huab cua (98 % RH) ntawm +60℃-tag nrho hauv ib lub thawv uas zaum ntawm koj lub keyboard.
4. Precision Qhov tseem ceeb
Lub chamber siv PT100 Class A sensors nrog 0.001℃daws teeb meem. Qhov kub hloov pauv nyob hauv ± 0.5 degree, thiab av noo nyob hauv ± 2.5% RH. Cov lej no tsis yog kev lag luam thov; Lawv raug txheeb xyuas tau raws li IEC 60068-3-5 calibration txoj kev.
Cov ntawv thov twg thiab cov qauv ntsuas twg siv cov ntsuas kub no?
Qhov kub ntau yam tsis muaj txiaj ntsig yam tsis muaj qhov kev sim tiag tiag. LIB's mini sub-zero chamber ncaj qha txhawb peb
tsev neeg ntawm cov qauv.
1. Khoom siv hluav taws xob: IEC 60068-2-1 thiab IEC 60068-2-2
Kev kuaj mob khaub thuas (IEC 60068-2-1, Ab):Tuav ntawm -40℃rau 2 txog 96 teev. Siv rau sab nraum zoov sensors, automotive ECUs, thiab cov khoom siv hauv chaw nres tsheb.
Cov cua sov qhuav (IEC 60068-2-2, Bb):Tuav ntawm +125℃rau 16 teev. Validates solder joints, yas vaj tse, thiab LCD polarizers.
LIB's T-50 model cycles from –40℃to +125℃with akub-up tus nqi ntawm 3℃/ minthiabtxias-down tus nqi ntawm 1℃/ min, yog li koj tsis tos txhua hnub rau kev hloov pauv.
2. Automotive: ISO 16750-4 thiab LV 124
Cov kauj ruam kub:-40℃rau +85 degree, 5℃kauj ruam, 1 teev ib kauj ruam.
Thermal shock (tsis ua haujlwm):-40℃rau +85 degree, 30-feeb dwells, 10 cycles.
Automotive labs feem ntau khiav cov kev xeem no rau kev tswj hwm roj teeb, ADAS lub koob yees duab, thiab lub qhov rooj kaw qhov rooj. LIB's chamber± 0.5℃stabilitytxawm tias thaum lub sij hawm ramps ceev, yog li qhov kev xeem tau rov ua dua.
3. Pharmaceutical: ICH Q1A Stability Test
Kev khaws cia ntev ntev:25℃± 2 degree, 60% RH ± 5% RH rau 12 lub hlis.
Nruab nrab:30℃± 2 degree, 65% RH ± 5% RH.
Ceev:40℃± 2 degree, 75% RH ± 5% RH rau 6 lub hlis.
Vim hais tias LIB lub chamber tswj cov av noo mus rau ± 2.5% RH, nws yooj yim haum rau hauv lub qhov rais ICH kam rau ua yam tsis xav tau ib qho chaw taug kev hauv chav.
Li cas LIB's Mini Sub-Zero Chamber Ua Haujlwm
Cov chav me me feem ntau siv lub tshuab tub yees ib-theem uas tawm tsam qis dua -40 degree. LIB's design txawv.
1. Lub Txias System
Lub siab hermetic compressor thawb cov tub yees los ntawm finned evaporator. Lub kiv cua centrifugal high-speed centrifugal tshuab cua sab hauv thoob plaws lub evaporator fins, ces circulates nws rov qab los ntawm qhov chaw ua hauj lwm. Kom ncav cuag –86℃, LIB siv lub tshuab tub yees cascade: ob compressors nyob rau hauv series, nrog ib tug kub exchanger ntawm theem. Thawj theem ua ntej txias rau theem ob lub tub yees, yog li theem thib ob tuaj yeem rub lub chamber mus rau qhov kub thiab txias.
2. Lub tshuab cua sov
Nickel-chromium hluav taws xob cua sov (cov lus teb ceev ceev) zaum ncaj qha rau hauv txoj kev airflow. Nrog 3℃/ min muaj peev xwm ua kom sov, lub kaw lus ua haujlwm sai thaum PID maub los hu rau cua sov. Tsis muaj thermal lag.
3. Humidity Control
Lub tshuab hluav taws xob tsim hluav taws xob ua kom sov me me ntawm cov dej deionized thiab txhaj cov vapor rau hauv cov dej ntws. Rau dehumidification, evaporator nto condenses ntau tshaj noo noo, uas ntws mus rau hauv lub kaw-voj dej-recovery system uas recycles txog li 50% ntawm condensate.
4. Tswj Logic
Lub 7-nti xim touchscreen khiav PID algorithm nrog kev them nyiaj pub rau tom ntej. Tus maub los kuaj cov PT100 sensors 10 zaug ib ob thiab kho cov cua sov lub zog, compressor lub luag hauj lwm, thiab humidifier tso zis txhua 2 vib nas this. Tias yog vim li cas qhov kub thiab txias hloov nyob rau hauv ± 0.5℃txawm tias muaj qhov rooj qhib lossis cov qauv cua sov.
Khiav tus qauv Lavxias (GOST 16962-1) ntawm LIB's Mini Sub-Zero Chamber
Ib qho ntawm cov kev xav tau tshaj plaws ntawm qhov txias-kub raws tu qauv yog los ntawmGOST 16962-1, tshwj xeeb tshaj yog qhov kev kuaj mob khaub thuas rau cov khoom siv hluav taws xob ntsuas rau kev ua haujlwm sub-Arctic.
Lub voj voog uas yuav tsum tau muaj (Test Method)
Tus qauv hu rau:
1. Stabilization ntawm -60℃± 2 degreerau 4 teev, nrog rau cov qauv kuaj tsis ua haujlwm.
2. Ruaj rau -10 degreentawm 0.5℃rau 1℃ib feeb.
3. Stabilization ntawm -10℃rau 1 teev.
4. Txoj kev mus rau +25 degreentawm 1℃/ min siab tshaj plaws.
5. Kev xeem ua haujlwmntawm ambient kub, xyuas cov kab nrib pleb, foob tsis ua hauj lwm, los yog parameter drift.
LIB Model That Executes This Test
LIB'sTSI-80(80 litre capacit) nce mus txog -86℃qhov kub thiab txias, yog li nws tuaj yeem tuav tau yooj yim -60℃nrog cov npoo. Dimensions: 900 mm × 1100 mm (dav × qhov tob), nyob tsuas yog 0.99 m² ntawm lub rooj ntev zaum.
