Kev luam ntawv yog nqa tawm ntawm qhov chaw ntawm cov khoom, electrostatic phenomena kuj tseem tshwm sim nyob rau saum npoo ntawm cov khoom. Cov txheej txheem luam ntawv vim muaj kev sib txhuam ntawm cov khoom sib txawv, kev cuam tshuam thiab kev sib cuag, kom tag nrho cov khoom siv rau kev luam ntawv ntawm hluav taws xob zoo li qub.
Kev puas tsuaj ntawm hluav taws xob static
1. cuam tshuam qhov zoo ntawm cov khoom luam tawm
Qhov saum npoo ntawm lub substrate them, xws li ntawv, polyethylene, polypropylene, cellophane, thiab lwm yam., yuav adsorb daim ntawv plua plav los yog ntab hauv huab cua, plua plav, impurities, thiab lwm yam., cuam tshuam rau kev hloov ntawm tus number case, kom lub paj tawg, thiab lwm yam. ., ua rau poob ntawm qhov zoo ntawm cov khoom luam tawm. Qhov thib ob, xws li tus cwj mem nrog cov nqi hluav taws xob, hauv kev txav ntawm qhov tso tawm, cov ntawv luam tawm yuav tshwm sim ntawm "electrostatic number case", nyob rau theem ntawm cov luam ntawv nyias feem ntau tshwm sim hauv qhov xwm txheej no. Nyob rau hauv lub tshav pob ntawm kev luam ntawv, xws li them tus number case tawm ntawm ntug ntawm cov luam ntawv, nws yog ib qho yooj yim mus tshwm nyob rau hauv lub ntug ntawm "ink whiskers".
2. cuam tshuam rau kev nyab xeeb ntawm kev tsim khoom
Nyob rau hauv cov txheej txheem luam ntawv vim muaj kev sib txhuam ceev, stripping yuav tsim hluav taws xob zoo li qub, thaum hluav taws xob zoo li qub tau yooj yim ua rau huab cua tawm, ua rau hluav taws xob poob lossis hluav taws. Thaum qhov hluav taws xob muaj zog heev, tus number case raug them yuav ua rau tus number case, hnyav hluav taws kub, ib qho kev hem thawj rau kev nyab xeeb ntawm tus neeg teb xov tooj.
Kev ntsuas hluav taws xob zoo li qub
1. Lub hom phiaj tseem ceeb ntawm kev ntsuam xyuas hluav taws xob zoo li qub hauv ntim thiab luam ntawv cov nroj tsuag yog txhawm rau txheeb xyuas qhov kev puas tsuaj; kawm kev tiv thaiv; txiav txim qhov ua tau zoo ntawm kev tshem tawm hluav taws xob zoo li qub. Yuav tsum xaiv tus neeg ua haujlwm rau cov khau tiv thaiv zoo li qub, cov khau ua haujlwm, cov khaub ncaws ua haujlwm tiv thaiv zoo li qub thiab txhua qhov kev kuaj xyuas hluav taws xob zoo li qub, cov txiaj ntsig yuav raug muab sib sau ua ke thiab tshaj tawm rau cov chaw haujlwm.
2. Kev faib tawm ntawm qhov kev tshawb nrhiav electrostatic: kev siv cov ntaub ntawv tshiab thaum cov khoom nrog kev ua haujlwm zoo li qub; cov txheej txheem ntau lawm them nqi kuaj xyuas; electrostatic kev ruaj ntseg ntsuas los txiav txim qhov ua tau zoo ntawm kev siv kev tshawb nrhiav.
(1) cov khoom uas muaj hluav taws xob zoo li qub kev ua haujlwm twv ua ntej yog raws li hauv qab no: cov khoom nto tiv taus. Kev siv cov ntsuas ntsuas siab lossis ntsuas ntsuas qhov ntsuas siab siab, qhov ntau ntawm 1.0-10 ohms.
(2) qhov tseeb ntawm lub cev raug them nrog cov khoom siv hluav taws xob zoo li qub yog raws li hauv qab no: kev ntsuas lub cev electrostatic muaj peev xwm ntsuas, electrostatic peev xwm ntsuas ntsuas nrog qhov siab tshaj plaws ntawm 100KV yog qhov tsim nyog, qhov tseeb ntawm 5.0 qib; nyob ib ncig ntawm qhov chaw kub thiab qhov txheeb ze humidity ntsuas; them lub cev khiav ceev ntsuas; combustible gas concentration txiav txim; conductive av rau av tiv thaiv tus nqi txiav txim; Deray lub tuam txhab ACL-350 yog tam sim no ntim Qhov tsawg tshaj plaws uas tsis yog-hu rau digital electrostatic ntsuas ntsuas.
Txoj kev tshem tawm hluav taws xob zoo li qub hauv kev luam ntawv
1. Tshuaj tua kab mob
Nyob rau hauv lub substrate nto coated nrog ib tug txheej ntawm antistatic tus neeg saib xyuas, kom lub substrate conductive, ua me ntsis conductive insulator. Kev tshem tawm tshuaj lom neeg ntawm daim ntawv thov hauv kev xyaum muaj ntau qhov kev txwv, xws li kev sib ntxiv ntawm cov tshuaj lom neeg hauv cov ntawv luam ntawv, cov ntawv zoo ntawm cov ntawv tsis zoo, xws li txo lub zog ntawm daim ntawv, adhesion, nruj, tensile zog, thiab lwm yam., yog li txoj kev siv tshuaj tsis tshua siv.
2. Txoj kev tshem tawm lub cev
Tsis txhob hloov qhov xwm txheej ntawm cov khoom siv cov khoom siv electrostatic tshem tawm, yog txoj kev siv ntau tshaj plaws.
(1) Txoj kev tshem tawm hauv av: kev siv cov hlau conductors tshem tawm cov hluav taws xob zoo li qub thiab lub ntiaj teb kev sib txuas, thiab lub ntiaj teb isotropic, tab sis txoj kev no tsis cuam tshuam rau lub rwb thaiv tsev.
(2) Kev tswj hwm kev tshem tawm cov av noo
Kev luam ntawv cov ntaub ntawv saum npoo tsis kam nrog cov huab cua noo nce thiab txo qis, yog li ua kom cov huab cua txheeb ze, koj tuaj yeem txhim kho cov conductivity ntawm daim ntawv nto. Lub khw luam ntawv tsim nyog rau ib puag ncig yog: kub txog 20 degrees, them lub cev ib puag ncig ntawm 70% lossis ntau dua.
(3) Cov txheej txheem xaiv cov khoom siv electrostatic tshem tawm
Lub tshuab luam ntawv feem ntau siv cov khoom siv electrostatic tshem tawm induction, high-voltage corona paug hom, ion flow electrostatic eliminator thiab radioisotope hom ob peb. Thawj ob ntawm lawv yog pheej yig, yooj yim rau nruab thiab siv thiab tsis muaj hluav taws xob atomic thiab lwm yam zoo yog siv dav:.
Induction hom electrostatic eliminator bar: uas yog, induction hom electrostatic tshem tawm txhuam, lub hauv paus ntsiab lus yog hais tias lub hau ntawm lub tshem tawm ze rau lub cev them, induction ntawm polarity thiab them lub cev ntawm electrostatic polarity ntawm qhov opposite nqi, yog li ua rau electrostatic neutralization. .
High-voltage paug electrostatic eliminator: muab faib ua hluav taws xob thiab high-voltage transformer hom, raws li qhov paug polarity yog muab faib ua unipolar thiab bipolar, unipolar electrostatic eliminator tsuas muaj kev cuam tshuam rau tus nqi, bipolar yuav tshem tawm txhua yam nqi. Nyob rau hauv cov txheej txheem luam ntawv yuav siv tau nyob rau hauv kev tshem tawm ntawm static hluav taws xob txhuam thiab high voltage paug hom ob ua ke ntawm txoj kev los mus tshem tawm cov hluav taws xob zoo li qub. Lub hauv paus ntsiab lus ntawm hluav taws xob zoo li qub tshem tawm qhov chaw teeb tsa: yooj yim rau kev khiav lag luam, tam sim ntawd tom qab qhov txuas ntxiv ntawm txheej txheej hnyav.
3. ntsuas tiv thaiv hluav taws xob zoo li qub
Qhov twg muaj cov khoom siv hluav taws xob hluav taws xob thiab qhov chaw muaj kev phom sij, yuav tsum nyob rau thaj chaw ib puag ncig uas muaj cov pa phem tuaj yeem tshwm sim, ntxiv dag zog rau kev ntsuas cua, kom cov concentration tswj tau qis dua qhov tawg; tiv thaiv electrostatic insulators nyob rau lub sijhawm ntawm hluav taws xob poob siab rau tus neeg teb xov tooj, lub insulator electrostatic muaj peev xwm tswj tau qis dua 10KV. Nyob qhov twg muaj qhov chaw tawg thiab hluav taws kub, cov neeg ua haujlwm yuav tsum hnav cov khau tiv thaiv zoo li qub thiab cov khoom tiv thaiv zoo li qub. Qhov chaw ua haujlwm yog paving nrog cov av conductive, conductive av tiv thaiv hauv av yog tsawg dua 10 ohms, kom tswj cov khoom siv hluav taws xob, cov neeg ua haujlwm raug txwv tsis pub hnav khaub ncaws hluavtaws fiber ntau (tshwj tsis yog cov khaub ncaws uas tau kho nrog cov tshuaj tiv thaiv zoo li qub. ) mus rau hauv cheeb tsam saum toj no, thiab nws yog nruj me ntsis txwv tsis pub hnav khaub ncaws hauv cheeb tsam saum toj no.
