Cov qauv kev xeem thiab cov txheej txheem kev ntsuam xyuas rau cov hnab looj tes tiv thaiv
Cov hnab looj tes los tiv thaiv los ntawm cov hnab looj tes tshwj xeeb los tiv thaiv. Cov ntaub ntawv siv yog nylon thiab cov fibers conductive. Qhov deb ntawm cov fibers yog 4 hli. Nws muaj zog elasticity thiab anti-static zog. Nws tsis muaj zog hluav taws xob uas tsim los ntawm tib neeg lub cev. Ua rau muaj kev puas tsuaj thiab tuaj yeem siv hauv chav tu chav.
Rau cov hnab tes tiv thaiv kev tiv thaiv kab mob, txoj kev kuaj thiab cov qauv xeem ntawv tseem ceeb heev. Ntau yam khoom siv yuav raug siv thaum kuaj. Muaj ob pawg ntawm megohmmeters rau kev ntsuam xyuas, 100V thiab 10V (± 5%), ntawm cov uas siv 100V los ntsuam xyuas ≧ 1X106 ohms thiab 10V siv los kuaj <1x106> Nyob rau tib lub sijhawm, koj xav tau lub pluaj los tiv thaiv qij pob zeb, lub plhaub hlau, thiab qhov ntsuas hluav taws xob.
Kev xeem yuav tsum tau ua tiav raws li cov txheej txheem qee yam. Cov txheej txheem tshwj xeeb yog raws li nram no:
1. Dej kub thiab av noo noo thaum lub sij hawm soj ntsuam yog: kub: 23 ± 3oC, txheeb ze ntawm cov av: 40% -60% ± 5%.
2. Ntsuam xyuas seb puas yog qhov ntaus ntawv hauv qhov kev kuaj thiab cov electrode megrow yuav ua tau zoo. Yog tias tsim nyog, ntxuav nws nrog ib daim ntaub mos muag nrog 70% isopropyl cawv.
3. Thaum lub sijhawm kuaj thawj zaug thiab tshuaj ntsuam, yuav tsum kuaj yam tsawg kawg yog rau yam khoom ntawm 6 yam.
4. Kos sab nraud pov thawj ntawm cov hnab looj tes. Muab cov qauv coj los soj ntsuam ntawm lub teeb vaj tse, thiab tom qab ntawd tso tus electrode ntawm lub megohmmeter rau sab nraud ntawm cov hnab looj tes. Lub electrode tsis pub tshaj tus qauv.
5. Tom qab cov electrode raug muab tso rau, thaum kuaj cov hnab looj tes tiv thaiv los tiv thaiv, siv 10V ntawm megohmmeter los xyuas. Yog tias qhov kev nyeem ntawv yog <1.0x107 ohm,="" siv="" daim="" ntawv="" no="" los="" txuas="" ntxiv="" mus=""> Yog tias qhov kev nyeem ntawv yog> 1.0X107 ohm, siv daim ntawv 100V rau kev kuaj xyuas. . Tom qab nyeem ntawv khov kho, sau cov ntawv nyeem thiab xyuas nws.
6. Siv tib lub sijhawm los soj ntsuam lwm cov qauv. Specification ntawm sab nraud kuj: ≥1.0 X 105 ohms rau <1.0x109>
Rau cov hnab looj tes tiv thaiv los tiv thaiv, yog cov ntaub ntawv tsuas yog ntsuas los ntawm kev soj ntsuam hauv nruj raws li txoj kev kuaj xyuas. Tsuas yog kom tsis txhob muaj kev raug mob rau cov khoom siv hluav taws xob thiab cov chips hauv kev ua haujlwm.
