Yuav ua li cas tiv thaiv hluav taws xob hauv hluav taws xob hauv cov tuam txhab tsim hluav taws xob?
Ua ntej, qhov cim ntawm hluav taws xob muaj hluav taws xob yog qhov tseem ceeb hauv cov hauv qab no:
(1) Kev ua haujlwm ntawm tib neeg lub cev, qhov hluav taws xob uas tau tsim los ntawm kev sib txhuam, kev sib cuag thiab kev sib cais ntawm tib neeg thiab khaub ncaws, khau, thom khwm, lwm yam zoo li no yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob.
(2) Thaum cov tshuaj fiber los yog cov paj rwb tag nrho cov rubbed tiv thaiv qhov chaw ua haujlwm thiab lub rooj zaum, ib qho hluav taws xob ntawm 6000V lossis ntau dua ntawm qhov hluav taws xob tau tuaj yeem tsim los ntawm cov tsoos tsho, thiab tib neeg lub cev raug them. Thaum sib cuag nrog lub ntaus ntawv, nws yuav ua rau paug thiab yooj yim ua puas tsuaj.
(3) Cov rwb thaiv tsev ntawm cov roj hmab los yog cov yas yas yog siab li 1013 Ω. Thaum nws rubs tawm tsam hauv av, nws generates hluav taws xob muaj hluav taws xob thiab them nyiaj rau tib neeg lub cev.
(4) Thaum pob zeb, xim zaj duab xis, thiab yas hnab yas nqa mus rau hauv lub ntim, qhov ntim ntawm lub cuab yeej thiab cov khoom ntim tuaj yeem ua hluav taws xob ntawm ntau pua volts los mus tawm ntawm lub cuab yeej siv.
(5) Cov hauj lwm ncaj ncees nto, uas yog electrostatically generated los ntawm kev sib txhuam.
(6) Cov rwb thaiv tsev tsis sib haum ntawm cov pob zeb, waxed ci, pem teb, roj hmab ntawv thiab lwm cov plag tsev yooj yim, thiab tus nqi sab nraud ntawm tib neeg lub cev tsis yooj yim.
Hauv kev tsim cov khoom hluav taws xob, nws tsis tuaj yeem tsim kom muaj hluav taws xob zoo li qub. Lub sijhawm ntawm hluav taws xob zoo li qub tsis yog muaj kev pheej hmoo, qhov kev nyab xeeb nta ntawm cov hluav taws xob uas muaj hluav taws xob thiab lub qhov hluav taws xob uas ua tawm. Qhov tseem ceeb ntawm kev tiv thaiv electrostatic yog "kev ntsiag to tshem tawm".
Yog li them sai sai rau cov khoom tiv thaiv electrostatic hauv cov chaw saum toj no.
Qhov thib ob, cov qauv ntawm kev tiv thaiv electrostatic yooj yim yog: a, inhibit qhov txua khoom ntawm cov nyiaj hauv lub xeev; b, ceev nrooj, yam xyuam xim thiab zoo tshem tawm cov nqi them uas muaj nuj nqi uas tau tsim tawm. Cov kev ntsuas muaj raws li nram no:
1. Hwjchim: Huv si yog tawm ncaj qha tawm ntawm hluav taws xob hauv lub ntiaj teb los ntawm kab kev txuas. Qhov no yog txoj kev coj ncaj tshaj thiab siv tau zoo rau kev ntsuas los tiv thaiv teeb meem. Rau cov neeg lag luam, txoj kev ua av xws li hlua los tiv thaiv txoj hlab pas, qhov av thiab av ua haujlwm, thiab lwm yam.
Huv yog siv los ntawm txoj kev hauv qab no:
1) Cov tib neeg lub cev yog grounded los ntawm lub dab teg.
Tib neeg lub cev yog grounded los ntawm nkawm khau puag (los yog khau khiab) thiab ib qho av zoo li qub.
2) Lub qhov chaw ua haujlwm yog grounded.
3) Qho kev ntsuas, cuab tam, cuab kav hlau.
4) Chav lo av zoo li qub, hauv pem teb (rooj) ncoo av.
5) Lub rooj sib txig thaiv kev thaiv tsheb, lub npov, cov av av.
6) Thaj tsam hauv lub rooj zaum uas muaj teeb meem los tiv thaiv.
2. Electrostatic shielding: Cheebtsam xoos xaim hluav taws xob (electrostatic sensitive components) yuav raug rau hluav taws xob hauv lub sijhawm thaum kev cia khoom lossis kev thauj mus los. Txoj kev tiv thaiv electrostatic tiv thaiv tau tuaj yeem ua rau lub zog ntawm sab nraud hluav taws xob hluav taws xob hauv cov cheebtsam hluav taws xob. Txoj kev siv ntau tshaj yog siv cov hnab looj (electrostatic shielding) thiab anti-static. Lub npov puv npo yog tiv thaiv. Tsis tas li ntawd, cov khaub ncaws hnav zoo li qub tau muaj qee cov tshuaj shielding ntawm cov khaub ncaws ntawm tib neeg lub cev.
3. Ion neutralization: Insulators yuav tsim hluav taws xob zoo li qub, thiab tshem tawm cov hluav taws xob hauv hluav taws xob los ntawm insulators yog siv tsis tau los ntawm kev siv av. Feem ntau siv txoj kev yog ion neutralization (siv cov shielding), piv txwv li hauv chaw ua haujlwm.
Qhov peb, cov ntaub ntawv tiv thaiv hluav taws xob thiab cov chaw tiv thaiv electrostatic
Yog li, nyob rau hauv cov ntaub ntawv los tiv thaiv static thiab anti-static cov chaw, lawv yog derived ntawm peb txoj kev, uas yuav muab faib ua anti-static metres, anti-static khoom rau grounding tshuab, anti-static ntim rau shielding, kev thauj mus los thiab cia ntawm ntaub ntawv pov thaiv cov khoom qub. Neutralized cuab yeej tshem tawm zoo li qub, nrog rau lwm cov khoom uas tsis zoo li qub.
Anti-static ntsuas
1. Lub pluaj pluaj / lub plab hnyuv / lub plab hnyuv npab ntawm cov ntom ntom siv: Siv lub tsho ntawm lub dab teg, cov xuab zeb, cov khau puag ncig los ua kom tau raws li txoj cai.
2. Thaum kuaj cov hlua khau thiab cov khau tiv thaiv zoo li qub, nws yuav tsum ntxiv ib daim hlau thiab cov xov hlau txuas nrog lub ntsuas.
3. Ntxiv rau lub tshuab hluav taws xob electrostatic ion cua siv: Siv sij hawm xyuas thiab tshawb xyuas qhov ion kiv cua tshuav thiab lwj sijhawm kom paub meej tias cov ion kiv cua ua haujlwm nyob rau hauv kev nyab xeeb ntau ntawm cov ntsuas.
4. Siv Electrostatic Field Tester Siv: Ntsuas daim teb electrostatic kom pom tau tias muaj qhov hluav taws xob hauv hluav taws xob, thiab nyeem ntawv nyob rau ntawm daim ntawv hluav taws xob kom kuaj lub zog ntawm lub tshuab hluav taws xob. Feem ntau cuam tshuam los ntawm ib puag ncig thiab qhov sib luag ntawm cov hluav taws xob zoo li qub, nws tsis yooj yim rau kev cuam tshuam qhov teeb meem tiag tiag.
5. Electrostatic shielding hnab tester Siv: Paub cov nyhuv ntawm daim thaiv electrostatic shielding.
6. Cov dej ntom ntom ntsuas kev ntsuas siv: ntsuas cov khoom xuabpeem, ua haujlwm tsis haum.
