Static hluav taws xob

Static hluav taws xob yog lub teeb ntawm phenomena nyob rau hauv uas muaj yog khaws cia ib tug dawb thiab tsis muaj zog txog cov hluav taws xob xwb. Nws yuav tshwm sim nyob rau hauv cais conductors rau ntawm qhov chaw los yog nyob rau hauv lub ib thooj ntawm dielectrics.

Tus txhuam generated los ntawm hu rau ntawm ob yam sib txawv ntawm cov siab zoo, ua rau electrification dielectrics. Qhov no yog vim qhov sib txawv molecular thiab atomic rog. Peb yuav hais tias static hluav taws xob yog tau nyob rau hauv yuam cai ntawm qhov nqi koj tshuav vim cov tshaaj los yog poob ntawm ib qho electron.

Piav tus txheej txheem heev yooj yim. Atom equilibrium mob yog tiav qhov twg tib tooj ntawm protons thiab electrons. Tsiv los ntawm ib tug atom mus rau lwm lub, electrons tsim zoo thiab tsis zoo ions. Nrog lawv tsis txaus thiab muaj static hluav taws xob.

Protons thiab cov electrons muaj tib lub fais xwb, tiam sis muaj ntau polarity. Nws yog ntsuas nyob rau hauv coulombs thiab txiav txim seb tus nqi ntawm hluav taws xob uas sau rau 1 sec. nyob rau hauv tus ntoo khaub lig seem ntawm tus neeg xyuas pib. Zoo li qub xwb yog ncaj qha proportional rau tus xov tooj ntawm tsis ruaj tsis khov ions, piv txwv li lub nyiaj tsawg los yog ntau heev ntawm electrons.

Static hluav taws xob yuav muaj peev xwm ua kom muaj. Qhov no yog vim tsis muaj kev zoo ion ntawm ib electron, yog li ntawd nws yuav tau txais los ntawm qhov tsis zoo particle free electron. Nyob rau hauv lem, qhov tsis zoo ion tej zaum yuav ib tug atom los yog molecule muaj ib tug loj tus naj npawb ntawm electrons. Nyob rau hauv cov neeg mob muaj yog ib tug tib electron uas yog tau neutralize lub zoo xwb.

Lub ntsiab ua rau entailing qhov tshwm sim ntawm static hluav taws xob yog raws li nram no:

• distancing los yog hu rau ntawm ob ntaub ntawv;
• ceev ceev kub ua viav vias;
• UV-tawg, lub zog hluav taws xob field, X-X-rays ;
• ua hauj lwm ua los ntawm tej (Vaj Huam Sib Luag saws los yog shredder);
• taw, i.e. cov tsos ntawm cov hluav taws xob field tshwm sim los ntawm zoo li qub xwb.

Cov tshwm sim, lub npe hu ua static hluav taws xob, yog ubiquitous nyob rau hauv lub neej txhua hnub. Electrostatic paug tshwm sim nyob rau heev cov nqi ntawm sab, tab sis thaum uas tsis muaj dej tsaws ntxhee. Nyob rau hauv cov ntaub ntawv no, muaj yog tsis muaj kev phom sij rau tib neeg.

Dua li no, lub ESD tiv thaiv yog tsim nyog, raws li nws yuav ua tau txaus ntshai rau ntau yam ntawm hluav taws xob khoom siv. Los ntawm nws heev feem ntau txom nyem transistors, Microprocessors, circuits, etc. Ua hauj lwm nrog cov xov tooj cua-hluav taws xob lub Cheebtsam, nws yog tsim nyog los muab kev txiav txim thiab tiv thaiv kom txhob tsub zuj zuj ntawm zoo li qub xwb.

Direct txaus ntshai tshwm sim rau xob sawv thaum lub sij hawm tsim ntawm cua daj cua dub huab. Huab vim zog ntawm huab cua ntws uas noo nrog dej vapor, tej zaum yuav tsim hluav taws xob ntswg. Raws li xws ntswg feem ntau tshwm sim nruab nrab ntawm tus them huab av. Nyob rau hauv cov ntaub ntawv no, yuav tsum tau muaj kev tiv thaiv los ntawm cov static hluav taws xob nyob rau hauv daim ntawv ntawm cov xob laim. Lawv yog cov tau mus nqa tawm paug ncaj qha mus rau hauv lub hauv av. Dhau li xob laim cua daj cua dub huab tsim tej hluav taws xob potentials yog cais rau cov khoom ua los ntawm cov hlau vim hais tias ntawm tus txheej txheem ntawm electrostatic induction.

Teeb hluav taws xob shocks, ua los ntawm ntau yam ces zoo li qub hluav taws xob, thaum xub thawj siab ib muag txawm, tab sis nws tsis yog li ntawd. Qhov no tshwm sim muaj peev xwm zais ib tug zoo txaus ntshai, raws li sparks muaj peev xwm ua rau muaj mob tiv cav tseb. Static hluav taws xob thiab kev tiv thaiv los ntawm nws - cov no yog cov ob lub tswv yim uas yuav tsum tau hu mus rau txhua leej txhua tus, txij li thaum vim hais tias ntawm ignorance tshwm sim tej zaum teeb meem loj.

Nyob rau hauv lub tsev thiab tom hauj lwm, yuav tsum tiv thaiv kom txhob muaj tshwm sim ntawm xws li ib tug ntau yam ntawm hluav taws xob. Ua li no, nqa tawm kev ntub tu. Cov kua - qhov no yog lwm loj kev hem thawj. Lawv yuav tsum tau siv nyob rau hauv ib tug zoo ventilated cheeb tsam uas tau cov tiv thaiv static hluav taws xob (thiab los ntawm tus tiv thaiv nyob rau hauv cov ntaub ntawv uas koj yuav luag guaranteed). Siv thaum ua hauj lwm nrog kua xws tej yam ntuj tso cov khaub ncaws, hauv pem teb yam machinery thiab tsuas yog hlau ntim rau lub cia ntawm cov dej uas yuav tsum tau nroj cig cuag sai sai.
