Ndai plasma particles ni a n-gun gaw, plastic molecule ni a chemical bond n-gun hte bung ai majaw, electron volt law law kaw nna shi ning du hkra, shanhte gaw plastic molecule ni a kata hta chemical n-gun yawm mat ai hpe hkrak hkrak shabyin ya ai majaw, arung arai ni hpe jahten sharun ai lam ni byin wa nna, ntsa lam n-gun hpe grai jat wa shangun ai. Dai hta n-ga, corona pru wa ai lam gaw ozone law law hpe shapraw ya ai. Ndai n-gun ja ai oxidant gaw plastic ntsa na molecule ni hte n-gun dat nna, carbon{8}} hpe madung tawn ai n-gun dat ni, peroxides ni, hte kaga n-gun ni hpe shabyin ya ai.
4. Corona Tsi lajang ai a akyu ni:
Corona tsi gaw plastic ntsa kaw na sau, hka n-gun, n san seng ai lam ni hpe hkrak sha shapraw kau ya ai sha n-ga, hka lim ai lam hte n-gun ja ai lam hpe mung grai kaja hkra galaw ya ai majaw, dai arung arai a ntsa na n-gun hpe jat ya lu ai. Ndai tsi lajang ai lam gaw, ndai sumla hkrung a polarity hpe mung jat ya nna, ntsa lam n-gun hpe jat ya ai hte, dai hku nna, matut mahkai lam hpe grau kaja hkra galaw ya ai. Hkringmang daju a n-gun atsam npu hta, nbung hta oxygen hpe ozone de galai shai kau nna, dai hpe oxygen hte nascent oxygen atom ni hku nna grau nna garan mat wa ai. Ndai nascent oxygen atom ni gaw n-gun ja ai oxidizing n-gun nga ai rai nna, polyethylene (sh) polypropyle molecule ni hta -carbon atom ni hte bai htang lu ai, dai gaw carbonyl hte hydroxyl hpung ni hpe shalawm ya ai. Ndai hkrang galai shai ai lam gaw, sumla hkrung molecule ni a polarity hpe jat ya ai, shanhte a ntsa na n-gun hpe jat ya ai hte, shanhte a affinity hpe adhesive ni a matu jat ya ai, dai hku nna, composite film ni a lapran na bond n-gun hpe grau kaja hkra galaw ya ai. Dai hta n-ga, active hydrogen hpe shapraw ai gaw, polyester adhesive ni hta active groups ni hte chemical hku nna bai htang lu ai, dai gaw bonding effect hpe grau nna jat ya lu ai.
Corona tsi gaw ink adhesion hpe grai kaja hkra galaw ya lu nna, printing hte htuk manu ai lam hpe mung jat ya lu ai. Tsi lajang ai aten hta, plasma ozone particle law law gaw plastic a ntsa na molecule ni hte matut mahkai nga ai. Dai tsaw ai -hkawm n-gun ni gaw, ndai sumla hkrung a ntsa hpe bawm jahkrat nna, polymer bonds ni hpe daw kau ya nna, free radicals law law hte n-gun n rawng ai ginjaw ni hpe shabyin ya ai.
