I. Sariyasenw ni taabolo minnu bɛ kɛ ka baara kɛ ni Corona sɛbɛnnikɛlan ye walasa ka filimu corona dɔn .
Corona pen ye baarakɛminɛn ye min bɛ se ka filimu dɔ sanfɛla fanga (Corona nafa) latigɛ joona ni enkiw ka jisigiyɔrɔ sumani ye. A sariyakolo sinsinnen bɛ jɛɲɔgɔnya kan dine nafaw (sanfɛ fanga hakɛ, 1 dyne=1 mn/m) ani tintiri jɛnsɛnni cɛ. Fɛn kɛrɛnkɛrɛnnenw ye ninnu ye:
1. Aw bɛ a yɔrɔ saniya: Aw bɛ filimu ko ni dɔlɔ ye walasa nɔgɔw kana nɔ bila sɛgɛsɛgɛli jaabiw la.
2. Layini sɛgɛsɛgɛli : Aw bɛ corona pen kɛ ka layini dɔ ja min janya bɛ se santimɛtɛrɛ 5 ma filimu sanfɛla la ani ka tintiri kɛcogo kɔlɔsi sekɔndi 2 kɔnɔ.
- Ni tintiri bɛ dɔgɔya ka kɛ jikuruw ye, a bɛ dugukolo sanfɛla fanga dɔgɔyali jira (korona nafa ka dɔgɔ ni hakɛ ye min taamasiyɛn bɛ sɛbɛnnikɛlan kan).
- Ni tintiri jɛnsɛnna cogo kelen na, a sanfɛla fanga bɛ sɔrɔ sɛbɛnfura kan walima a sanfɛ.
3. Gradient Verification: Aw bɛ segin sɛgɛsɛgɛli kan ni corona pen nafaw ye Dyne hakɛw danfaralenw na (misali la, 38, 40, ani 42 Dyne) walasa ka filimu ka corona hakɛ yɛrɛ dɔn ka ɲɛ.
*Kɔlɔsili*: Sɛgɛsɛgɛli sigida ka kan ka mara degere 25±5 la ani nɛnɛ hakɛ 60% duguma walasa ka funteni ni nɛnɛ bali ka nɔ bila tintiri baara la (aw ye ASTM D2578 lajɛ).
II. Corona nafa sɛgɛsɛgɛli ani sɛgɛsɛgɛli danfara filimuw la minnu bɛ lamini ani filimuw matte .
1. Laminated film corona value: industry standard ye 38-42 Dynes ye (Data Source: ISO 8296-2016). Kunba minnu b’a la:
- Laminatɔw bɛ dilan ni bopp/Pet fɛnw ye cogoya la, minnu bɛ fanga caman wajibiya dugukolo sanfɛla la walasa ka enki walima kola nɔrɔli sabati.
2. Matte film corona nafa: A ka ca a la, a ye 32-36 Dynes (Data Source: Tappi T458 Standard) ye. Danfara minnu bɛ olu ni ɲɔgɔn cɛ olu ye:
- Film matte surfaces ye frosté ye, ani ka dɔ fara gɛlɛya kan, o bɛ dɔ bɔ Dyne nafa nafama na;
- Ni aw bɛ sɛgɛsɛgɛli kɛ, aw bɛ corona pen kɛ ni a kun ye min ka bon walasa a kana jateminɛ kɛ ka ɲɛ ka da a kan a ɲɛda cogoya tɛ kelen ye.
iii. Ko kɛrɛnkɛrɛnnenw ani gɛlɛya minnu bɛ sɔrɔ tuma caman na .
1. Gɛlɛyaw ɲɛnabɔli corona nafaw kan minnu tɛ kelen ye filimuw kan:
- Ni sɛgɛsɛgɛli jaabiw bɛ wuli kosɛbɛ, a ka ɲi ka segin ka sɛgɛsɛgɛli kɛ ni joli furakɛli fɛɛrɛ ye (a tiɲɛni ±1 dyne).
- Ni korona ma dafa filimu matɛri yɔrɔ dɔw la, a bɛ se ka fara korona furakɛli sira kan (se ka kan ka ladilan ka se 50-100W ma).
2. Nafa minnu bɛ ɲɔgɔn sɔsɔ, olu ɲɛfɔli baarakɛlaw fɛ:
- Yɔrɔ wɛrɛw minnu bɛ filimu kelen kan, olu bɛ se ka danfara sɔrɔ 2-3 dynes, o ye normal ye (ISO standard tolerance range).
- Ni filimu corona nafa ka dɔgɔ ni dynes 38 ye, delamination composite bɛ se ka kɛ (aw ye GB/T 8808-2023 ka peel fanga sɛgɛsɛgɛli wajibiyalenw lajɛ).
