Pa electrostatic charging (CORONA CHARGING)

Cov pa hluav taws xob hluav taws xob (Corona Charging) los ntawm kev hla cov hmoov los ntawm qhov chaw siab-voltage electrostatic.

High voltage (40-100 kV) concentrated nyob rau hauv lub nozzle ntawm rab phom txau ua rau ionizing ntawm huab cua dhau los ntawm rab phom tsuag. Kev hla ntawm cov hmoov los ntawm cov huab cua ionized no ces tso cai rau cov ions dawb kom ua raws li qhov feem ntawm cov hmoov nplej thaum tib lub sijhawm siv cov nqi tsis zoo rau lawv.
Nyob nruab nrab ntawm rab phom electrostatic thiab cov khoom raug coated, muaj cov hauv qab no:

Nws yog ib qho tseem ceeb ntawm qhov tseem ceeb kom ua tiav qhov ua tau zoo tshaj plaws ntawm kev them cov hmoov hmoov thaum lub sij hawm tus txheej txheem nws tus kheej. Cov txheej txheem uas siv cov cuab yeej txau kuj ua rau muaj kev vam meej.
Cov hmoov uas tsis tau them nqi yuav tsis ua raws li cov khoom thiab yuav rov ua dua. Txawm hais tias kev rov ua dua tshiab yog ib txwm muaj hmoov txheej, nws yog qhov zoo dua los khaws cov khoom siv rov ua dua tshiab kom tsawg.
Dawb ions yog me me thiab nyob deb ntau ntawm cov xov tooj ntawm cov hmoov nplej. Ntau cov ions dawb yuav txav mus nrawm rau ntawm cov khoom xa mus, tib lub sijhawm, cov nqi tsis zoo rau nws. Qhov kom muaj nuj nqis ntawm cov ions dawb yog tag nrho nyob ntawm kev tswj hwm qhov xav tau voltage. Superfluous high voltage ua ib qho khoom siv ntau tshaj ntawm cov ion dawb, uas nyob rau hauv lem ua rau cov hmoov txheej zoo kom ua tiav thiab, tsis tsawg, muab cov dej tsis zoo (rov qab-ionizing). Qhov av tsis txaus ntawm cov khoom yuav ua rau qhov xwm txheej tsis zoo

Siv high voltages ua hluav taws xob teb kab ntawm lub nozzle ntawm rab phom thiab cov khoom, nrog rau cov hmoov uas qhia ib tug nyiam ua raws li cov kab no. Cov khoom ntawm cov qauv nyuaj yuav muaj qhov ceev tshaj plaws ntawm cov kab teb ntawm lawv qhov chaw sab nrauv, tshwj xeeb tshaj yog nyob rau sab nrauv. Ib yam li ntawd, qhov qis dua ntawm cov kab teb yuav tshwm sim ntawm sab hauv ces kaum thiab indentations.

Qhov tshwm sim no feem ntau hu ua Faraday Cage effect uas ua rau muaj teeb meem nrog cov hmoov thov uas cov kab teb qhov ceev yog qhov qis tshaj, raws li qhia hauv daim duab hauv qab no:

Cov hluav taws xob siab dua ua rau cov nyhuv Faraday Cage khaus ntau dua, ua rau cov yeeb yaj kiab tuab ntawm cov hmoov uas qhov chaw nkag tau yooj yim dua thiab cov txheej txheej nyias nyias rau thaj chaw nyuaj dua mus txog. Nws yog ib qho tseem ceeb uas yuav tsum tau teeb tsa rab phom rab phom voltage txaus siab uas tso cai rau kev them nyiaj zoo tshaj ntawm cov hmoov. Txawm li cas los xij, kev siv hluav taws xob hluav taws xob siab tsis tsim nyog muaj ntau yam tsis xav tau. Dab tsi characterizes ib tug txawj hmoov txheej tus neeg teb xov tooj yog muaj peev xwm mus cuag qhov zoo tshuav nyiaj li cas.
