Planti hevi bilong korona tritmen i save stat wantaim wanpela namba we nogat wanpela man i raitim. Ol opereta i save kisim wanpela 'treater', na putim pawa long wanem kain seting ol i bin yusim pastaim, na ol i no save sekim sapos dispela namba i givim stretpela 'dose' bilong 'substrate', 'width' na 'line speed' bilong nau. Corona trita pawa em i no wanpela samting yu laikim - em i wanpela 'derived value', na sapos yu skelim stret em i narapela samting namel long 'consistent adhesion' na wanpela lain we i no wok gut inap long tripela aua. Dispela gaid i karamapim ol fomula, ol yunit, na ol mak bilong korona pawa long prodaksen.
As Fomula Bilong Korona Trita Pawa
Tritmen dos em ol i soim olsem 'watt density': 'watts' long wan wan skwea sentimita long wan wan minit bilong ples we ol i bin tritim.
Watt density (W/cm2/min)=Applied power (W) ÷ [ Web width (cm) × Line speed (cm/min) ]
Wok long ol wankain yunit. Sapos ol i givim bikpela bilong en long mita na spit long mita long wanpela minit, yu mas multiplaim tupela long 100 long tanim i go long sentimita.
Wanpela gutpela eksampel: wanpela 1.6 m waid lain i ron long 250 m/min na jenereta i yusim 24 kW.
- Web width=160 cm
- Spit bilong lain=25,000 cm/min
- Tritim eria long wanpela minit=160 × 25,000=4,000,000 cm2/min
- Watt density=24,000 ÷ 4,000,000=0.006 W/cm2/min
Dispela namba i luk liklik bikos dispela fomula i save kamapim ol 'watts' long wanpela 'square centimeter' long wanpela minit. Em i gutpela long multiplaim long 1,000 na ripotim risal long miliwat, o long wok long W/m2/min long ol indastrial namba. Ol data pepa bilong indastri i save kolim 'watt density' long W/cm2/min na skelim i go long wanpela 'practical range', olsem na oltaim yu mas save long wanem kain 'convention' wanpela saplaia i yusim pastaim long yu skelim ol namba.
Rilesensip we i bikpela samting:pawa bilong korona trita i mas i go stret wantaim spit bilong lain na wantaim bikpela bilong web.Dabol spit na yu nidim dabol pawa bilong wankain dos. Dispela em i as na wanpela 'treater' we i wok gut long 150 m/min i no wok gut long 300 m/min maski i no gat senis long ol ikwipmen.
Wok i go bek long sabstret bilong yu
Gutpela rot em long stat long 'substrate' na kisim pawa yu nidim.
- Luksave long famili bilong sabstretna 'surface energy' bilong en we ol i no bin stretim.
- Setim mak bilong 'dyne'long daunstrim proses - planti taim 38 i go long 42 dynes bilong ol polyolefin, 45 i go long 48 bilong PET.
- Yu mas makim wanpela 'baseline watt density'long rekomendesen bilong saplaia o long ol data bilong prodaksen bipo bilong dispela sabstret.
- Multiplaim long web eria long wanwan minityusim bikpela na spit bilong nau.
- Putim wanpela mak- planti taim 15 i go inap 25 pesen - bilong karamapim lapun, senis bilong ples na bagarap bilong 'electrode'.
- Toksave olsem jenereta inap long givimna olsem 'electrode' na 'dielectric' inap long rausim hat we i kamap.
Ol 'baseline watt densities' bilong ol komon kes i stap insait long ol dispela 'band':
| Sabstret | Tipikel dyne mak | Beslain watt densiti | Ol toksave |
|---|---|---|---|
| LDPE / LLDPE film | 38–42 | 6–10 | Ful waid tritmen |
| BOPP piksa | 38–40 | 5–8 | Ol 'slip aditives' i save daunim bon |
| PET film | 45–48 | 3–6 | Ova-risk bilong tritmen |
| Aluminium foil | 42–46 | 6–12 | Bikpela rol 'thermal load' |
| Pepa / bod | 40–44 | 4–8 | I save pilim wara |
| Film we i gat ain long en | 44–50 | 3–5 | Lukautim metal leia |
| Sabstret we i gat koting | 40–46 | 3–6 | Diuti saikel i go daun |
Dispela em ol stating poin. Olgeta lain i gat 'heat balance' bilong en, 'dwell geometry' na 'ambient conditions', olsem na tingim ol olsem namba wan estimet na konfemim long rot bilong skelim.
Korona Trita Pawa Reting na Jenereta Hedrum
Ol jenereta i save kisim mak long autput pawa, tasol namba bilong nemplet i no samting we i save kamap long web. Ol lus i save kamap long trensfoma, long hai-voltej kebol na long 'electrode assembly' yet. Tingim olsem namel long 10 na 25 pesen bilong 'nameplate rating' bai i no stap long taim bilong 'discharge'.
Lo bilong sais:makim wanpela jenereta we i no winim 30 pesen antap long mak bilong prodaksen yu bin skelim.Dispela 'headroom' i karamapim tripela bikpela nid. Namba wan, ol senis bilong prodak i go long ol hevi watt density. Namba tu, 'electrode' na 'dielectric ageing', we i save apim 'voltage' we i nidim long wankain 'dose'. Namba tri, ol kondisen bilong ples - bikpela humiditi i save pasim wara i kapsait, olsem na wanpela lain we i ron gut long taim bilong kol i ken hatwok long taim bilong monsun.
Sapos yu no sais tumas long wanpela jenereta, dispela i save mekim na yu no inap mekim wanpela samting oltaim. Taim ol i winim mak bilong pawa bilong korona trita, spit bilong lain i kamap olsem wanpela samting tasol, na daunim spit bilong lain long mekim tritmen i wok em i wanpela rot we i gat bikpela pe bilong stretim hevi bilong sais bilong ol ikwipmen.
Sapos yu mekim bikpela samting tumas, dispela i gat pe bilong en yet. Wanpela jenereta we i ran aninit tru long mak bilong autput bilong en i no save wok gut long sait bilong wevfom kwaliti, na ekstra kapasiti em i kepital we i sindaun nating. Traim long kisim gutpela mak, na i no bikpela samting.
Wanem samting i pasim strong bilong korona trita long wok
Yu no inap long apim pawa tasol. Planti ol mak bilong bodi i kam insait.
Dielektrik brukdaun bilong rol karamapim.Olgeta 'dielectric' i gat mak bilong 'watt density' we ol i ken karim. Sapos yu winim dispela na karamapim bai kamapim ol 'conductive tracks', na bihain ol i sutim. Ol silikon karamapim i no inap long karim hevi olsem ol 'ceramic'. Dispela em i strongpela siling long planti instolesen.

Ansa bilong ol enjinia em long mekim wok long taim bilong stap longpela taim na i no long pawa. Wanpela bikpela rol diamita, wanpela bikpela tritmen futprin o wanpela slopela lain olgeta i save mekim taim we web i spendim long rausim wara, na larim yu long kisim mak bilong marasin long liklik pawa bilong korona trita. Pawa i liklik i min olsem i no gat planti hat, i gat longpela laip bilong 'dielectric' na i gat bikpela 'operating window'.

Wanpela kalkulesen we ol i makim long taim bilong kirapim wok em i no wanpela set poin oltaim. Mekim ol dispela pasin i go insait long lain.
Raitim 'dose', na i no 'power setting' tasol.Rekodim bikpela, spit, pawa na 'watt density' long stat bilong olgeta ran. Taim 'adhesion' i go daun, 'log' i soim sapos dispela wok i senis.

FAQ
Q1: Hau bai mi ken skelim pawa bilong korona trita mi nidim?
Multiplaim mak bilong 'watt density' bilong yu wantaim eria we yu bin tritim long wanpela minit, we em i 'web width' taims 'line speed' na tanim i go long ol 'consistent units'. Orait putim 15 i go inap 25 pesen mak na konfemim olsem mak bilong jenereta i stap antap long dispela namba inap 30 pesen.
Q2: Bilong wanem tritmen bilong mi i no wok gut taim mi skruim spit bilong lain?
Spit i save daunim taim bilong stap insait long 'discharge', olsem na wankain 'corona triater' pawa i save givim liklik 'dose'. Yu ken apim pawa stret o apim mak bilong tritmen wantaim bikpela rol.
Q3: Wanem em i nomol watt densiti bilong korona tritmen?
Long ol 'polyolefin films' long wanpela 'extrusion coating' o 'printing line', 5 i go inap 12 W/cm2/min i karamapim planti taim taim ol i skelim i go long konvensen bilong saplaia. PET na ol metalised film i save ron daunbilo, ol foil na bod i save ran antap.
Q4: Mi ken tritim planti tumas?
Yes. Ova-tritmen i save kukim pes, kamapim wanpela wik baundri leia, kamapim planti ozone, hariapim 'dielectric wear' na inap long kamapim tritmen long baksait long ol liklik film. Moa pawa bilong korona trita i no gutpela hariap.
Q5: Hamas spes mi mas lusim insait long jenereta?
Inap 30 pesen antap long mak bilong prodaksen we ol i bin skelim. Dispela i save kisim olpela 'electrode', senis bilong 'humidity' long olgeta sisen na ol senis bilong prodak long bihain taim na i no fosim 'line speed reduction'.
Q6: Kondisen bilong 'electrode' i save senisim pawa we ol i nidim?
Em i save mekim. Taim arere bilong 'electrode' i raun na 'dielectric' i bagarap, spes i senis gut na moa 'voltage' i mas kamap long wankain 'dose'. Wanpela pawa rikwaemen i go antap em i wanpela eli mentenens signal.
Q7: Hamas taim mi mas skelim gen 'dose'?
Kalkuletim gen taim 'substrate', 'width' o 'line speed' i senis, na sekim gen 'set point' long olgeta kwata. Ranim kalkulesen long stat bilong olgeta prodaksen kempen na noken dipen long wanpela inherited seting.

Corona trita pawa em i wanpela veliu we ol i kisim. Stat wantaim 'substrate' na 'dyne level' yu laikim, makim wanpela 'baseline watt density', multiplaim wantaim 'trited area' long wanwan minit long 'width' na 'speed' bilong yu, putim 'margin', na konfemim olsem jenereta na 'dielectric' inap long karim hevi. Orait raitim risal na lukluk long 'trend', bikos namba we i wok tude bai i go daun taim ol 'electrode' i go lapun na ol sisen i senis.
