Corona Tsi lajang ai lam a hpang na hpaji masa
Corona tsi ladat gaw nbung plasma tsi ladat langai rai nna, plastic ntsa grup yin na nbung hpe ionize galaw na matu, n-gun kaba ai-wan n-gun hpe jai lang ai. Ndai ladat gaw ion, electron, free radicals ni a n-gun rawng ai makau grup yin hpe shabyin ya ai. Ndai n-gun ja ai amyu bawsang ni gaw polymer npu hte hkrat sum mat ai shaloi, molecular matut mahkai lam ni hpe dawm kau nna, carbonyl, hydroxyl, carboxyl zawn re ai polar bungli hpung ni hpe shapraw ya ai.

Print galaw mai ai lam hte Product galaw lu ai atsam a matu ahkyak ai akyu ara ni
Corona tsi lajang ai hku nna ntsa lam a atsam ni hpe jat ya ai gaw plastic arung arai galaw shapraw ai a matu hkam sha lu ai akyu ara ni hpe hkrak sha ga gale ya ai:
1. Grau kaja ai Ink n-gun hte dip shapraw ai atsam:Ntsa n-gun jat wa ai hte polar shara ni nga ai gaw ink molecule ni a matu ngang kang ai anchoring point ni hpe jaw ya ai. Dai hku galaw yang, grau htuk manu ai, grau htoi tu ai resolution hte nsam hpe sadi dung ai hku ka shapraw lu ai. Dai gaw n gram lajang ai, n-gun n law ai -npu ntsa ni hta byin chye ai ink beading, crawling, shing nrai n bung ai coverage zawn re ai n kaja ai lam ni hpe yeng seng kau ya ai.
2. Hkrang shapraw ai hte lamination hpe grau kaja hkra galaw ai:Laika shapraw ai hta lai nna, corona tsi lajang ai lam gaw, bungli galaw ai shingnip ni (ga shadawn, makawp maga ai varnish, pat shingdang ai shingnip ni) hpe kam mai ai hku shinggrup da lu na matu hte lamination galaw ai lam ni hta ngang kang ai hku shinggrup da lu na matu ahkyak nga ai. Dai gaw, dai arai a ngang grin ai lam, n-gun n rawng ai lam, yawng hpe n-gun jaw ya ai.
3. Waste hpe shayawm ya nna, Process hpe grau kaja hkra galaw ya ai:Misprints hte adhesion hkrat sum ai lam ni hpe pat shingdang ai hku nna, corona tsi lajang ai lam gaw, galaw shapraw ai lam hta jai lang ai lam, bai galaw ai lam, n bungli galaw ai aten ni hpe shayawm ya lu ai. Dai gaw, galaw shapraw hpang ai aten kaw nna, n galai shai ai, madang tsaw ai -quality pru ai lam hpe madi shadaw ya nna, grau n-gun ja ai hte grau ngang grin ai galaw shapraw ai lam ni hpe galaw lu na matu karum ya ai.
4. Hkamja lam hte tsawm htap ai masat masa ni hpe hkan sa ai lam:Packaging, tsi mawan ni, hte jai lang ai arung arai ni a matu, kam mai ai hku dip shapraw ai lam gaw tara upadi ni hpe hkan sa ai lam (ga shadawn, hti mai ai masat da ai lam, batch codes) hte brand hpe hkam la ai lam ni hte matut mahkai nga ai. Corona tsi lajang ai lam gaw, gat lawk ni ra sharawng ai premium aesthetic finish hpe lu la ai sha n-ga, ngang kang ai shimlam madang ni hpe hkan sa lu hkra karum ya ai.
Application hpe myit yu ai lam hte galaw sa wa ai lam hpe hkang ai lam
Corona tsi ladat a akyu gaw masa lam law law hpe hkrak hkrak hkang lu ai hta madung nga ai. Ra ai tsi tsi ai lam a n-gun gaw, arung arai amyu, web a lawan ai lam, galu kaba ai lam ni a majaw re. Ndai lam ni hpe madung tawn nna ra ai n-gun hpe sawn la nna, npu ntsa hpe atsawm sha galai shai lu na matu sawn la mai ai. Dai lam hpe hkang zing da ai masa langai a daw langai hku nna mu mada na matu mung ahkyak nga ai. Ga shadawn, quality hpe hkang zing na matu lang ai chyam dinglik ntsin ni a atsam ni hpe (diiodomethane (sh) hka zawn re ai) hkrak chye ra ai (sh) grup yin masa ni hta shadawn ra ai, hpa majaw nga yang, galai shai ai lam ni gaw n bung ai npu na n-gun hpe sawn shapraw ai lam ni hpe byin shangun nna, dai hku nna kam hpa n mai ai lam hpe yu reng ai lam ni hpe byin shangun chye ai.
Dai hta n-ga, plastic amyu myu gaw corona tsi lajang ai hpe laklai ai hku bai htang ai. Hpaji masa hte seng ai hpun palawng ni hta law law lang ai nylon hte polyester zawn re ai synthetic fiber ni mung ndai tsi ladat hpe lai di nna, dye hpe hkam la lu ai hte fiber hpe hka ja lu hkra galaw ai. Tsi ladat a akyu gaw, hpang na lam law malawng a matu aten galu-nga ai raitim, aten ladaw ni na wa ai hte maren yawm mat wa chye ai-dai hpe "aging" ngu shamying ma ai. Dai majaw, tsi tsi ngut ai hpang kade nna yang, dip shapraw ai (sh) coating galaw ai shaloi, kaja dik ai mahtai hpe lu la mai ai.
