Los tiv thaiv zoo li qub nkawm khau tu thiab ntxuav
Cov khau tiv thaiv zoo li qub (zoo li qub dissipative) xav tau kev tu nquag thiab tu kom lawv ua haujlwm kom zoo. Yog tias khau tsis tau tswj, lawv yuav plam tag nrho ESD cov haujlwm. Los tiv thaiv zoo li qub nkawm khau
Txhawm rau txhawm rau tswj ESD kev ua tau zoo, nkawm khau yuav tsum raug tswj thiab tu huv si tsis tu ncua. Hauv qab no yog cov kev qhia kom tu txhua lub limtiam:
1. Khaws qhov tawm sab nraud kom huv, tsis muaj plua plav, tshuaj khib nyiab thiab lwm yam paug. Siv cov tshuaj ntxuav tes nruab nrab thiab dej los txhuam cov khoom seem.
2. Khaws sab hauv ntawm nkawm khau kom huv. Tshem tawm cov insole thiab ntxuav lub insole thiab sab hauv ntawm lub khau nrog lub tshuab nqus tsev.
3. So cov tawv kom tawv dua nrog ib daim ntaub damp.
Lub insole yog qhov tseem ceeb rau qhov kev tawm tsam los tiv thaiv kev ua haujlwm ntawm cov khau. Tsis txhob hloov lossis hloov cov qub nrog cov pob zeb tsis muaj ESD.
Ob txhais ko taw qhuav lossis thom khwm thiab ib puag ncig qhuav yuav ua rau kev ua haujlwm ntawm ESD nkawm khau. Vaum yog qhov tseem ceeb rau ESD kev ua tau zoo. Tsis txhob siv cov hmoov txheej khau uas yuav txo cov av noo hauv nkawm khau.
Cov lus qhia rau kev siv:
1. Cov khau tiv thaiv zoo li qub yog cov khau tiv thaiv uas tuaj yeem tshem tawm hluav taws xob zoo li qub ntawm tib neeg lub cev thiab tiv thaiv cov hluav taws xob hluav taws xob qis dua 250 volts. Cov khoom no yog tsim raws li GB4385-1995 tus qauv.
2. Mas siv los tiv thaiv tib neeg lub cev los ntawm hluav taws xob zoo li qub, xws li roj av, tshuaj lom neeg, thee, luam ntawv, roj hmab, kho mob, huv, hluav taws xob thiab lwm yam kev lag luam uas muaj hluav taws xob zoo nkauj, xws li hlawv, tawg, thiab lwm yam.
3. Thaum hnav cov khau uas muaj conductive, thov tsis txhob hnav cov hnab looj tes insulating thiab tiv thaiv ins insoles ntawm tib lub sijhawm. Nws yog txwv tsis pub siv khau los tiv thaiv kev tiv thaiv zoo li insulating nkawm khau.
4. Qhov chaw uas cov khoom siv los tiv thaiv kev tiv thaiv zoo li qub yuav tsum tau tawm tsam ntawm hluav taws xob zoo li qub, thiab qhov chaw uas siv cov khau hluav taws xob yuav tsum tau xaim hluav taws xob kom ua tiav qhov zoo los tiv thaiv kev ua haujlwm lossis kev coj ua.
5. Nws yuav tsum siv nrog cov khaub ncaws tiv thaiv zoo li qub, them sai sai rau cov khoom ua kom huv, tsis muaj dej tsis muaj pov thawj thiab dej noo.
6. Feem ntau, qhov tshuaj tiv thaiv yuav tsum ua nyob rau hauv 200 teev thaum hnav. Yog tias qhov tawm tsam tsis dhau qhov teev hauv siab, nws siv tsis tau ua cov khau tiv thaiv tawv tawv. Cov khau los tiv thaiv zoo li qub xav tau qhov tawm tsam ntawm 100K thiab 1000 ohms.
