Core Issue: Matsan ai Corona tsi lajang ai lam a akyu ara ni hpe hparan ai lam ni
Hpa majaw nga yang, n kaja ai hku ka ai, n-gun n rawng ai, n-gun n rawng ai, n-gun n rawng ai, npu ntsa na n-gun n-gun (dyne pen chyam dinglik ai lam hkrat sum ai) n-gun n-gun n-rawng ai.
Root Cause: N law htum n-gun n rawng ai arung arai ni. Corona tsi gaw nbung hpe tsaw ai- ai hku nna ionize galaw nna, ozone hte plasma hpe shapraw na matu, n-gun kaba ai{2}}voltage hpe shapraw ya ai. Ndai tsaw ai-}energy particles ni gaw, n-gun kaba ai arung arai ni (ga shadawn, PE, PP, BOPP), oxidation hte etching byin shangun ai majaw, npu na n-gun hpe jat wa shangun nna, ink hte coatings ni hte matut mahkai lam hpe jat wa shangun ai.
Core Parameter masum a matu tuning Tips ni
1. Power – Tsi lajang ai lam a "myit masa"
Parameter Definition: Corona tsi lajang ai jak a pru wa ai n-gun, law malawng gaw kilowatts (sh) watts hta centimeter langai hta. Dai gaw, n-gun dat n-gun hpe hkrak dawdan ya ai.
Tara:
Insufficient Power: N-gun n rawng ai hka n-gun gaw, arung arai ntsa hta molecular chain ni hpe atsawm sha hpaw ya lu ai majaw, tsi lajang ai lam hta n-gun kya ai hte npu na n-gun hpe shayawm ya lu ai.
N-gun grai law ai: Arung arai ni hpe "hten run mat ai" (sh) "ntsa{ 0}} tsi lajang ai lam ni hpe shabyin ya lu ai". Over-treatment gaw, arung arai ntsa hpe jahten kau ya ai, molecular chain ni hpe daw kau ya ai, n-gun hpe shayawm ya ai, manam pyaw ai baw ni hpe pyi shapraw ya ai (ozone htum mat ai arung arai ni), shing nrai, pat shingdang ai lam ni hpe shabyin ya ai (dai gaw kaga roll langai a hpang maga de hkan nang hkan sa ai).
Tuning Tips:
Low to High: Shawng ningnan lang lang ai arung arai nnan hpe tuning galaw ai shaloi, n-gun n law ai kaw nna hpang nna, loi loi hte loi loi hte jat wa u.
Observe Electrodes: Kaja dik ai hka pru ai masa gaw, electrode hte roller lapran na langai sha re ai nsam hpraw ai corona rai nna, ngang grin ai hte matut manoi "hpyi ai" nsen hte rau. Bright white arcs (sparking) gaw grai n-gun (sh) awu asin byin ai/hka n-gun n rawng ai electrodes/dielectric layers ni hpe madun ai.
Reference Standard: Shapraw ai plastic sumla hkrung ni a matu (ga shadawn, BOPP, CPP, PE) a matu, n-gun atsam gaw 1.5~3.0 W/cm2 lapran rai nga ai. Ndai range a median kaw na chyam dinglik hpang mai ai (ga shadawn, 2.0 W/cm2).
2. Lawan ai – Tsi lajang ai "Aten"
Parameter Definition: Corona tsi lajang ai electrode npu kaw lai wa ai arung arai ni a lawan ai lam.
Tara:
Grai law hkra High Speed: Dai arung arai gaw aten kadun laman hta n-gun n rawng ai shara hta nga ai, dai majaw, n-gun ja ai wa n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-nga ai hte tsi tsi ai lam n kaja ai.
Grai law hkra n-gun n rawng ai: Aten galu tsi lajang ai aten gaw, tsi tsi hkam la ai lam hta grau loi ai hku byin wa ai (grau nna, n-gun kaba ai aten hta), n-gun hpe jahten kau nna, arung arai ni hpe jahten sharun ai lam ni byin chye ai.
Tuning Tips:
Linkage hte rau nga ai:Power hte lawan ai lam gaw grai matut mahkai ai parameters ni re. Tsun mayu ai gaw: Tsi lajang ai lam a akyu ≈ Power / Speed. Dai akyu hpe grau kaja hkra galaw na matu, "n-gun hpe jat wa ai" (sh) "- lawan ai hpe shayawm ya ai" ngu ai hpe.
Speed Fixing and Power Tuning: Production hta, bungli galaw ai lam hta, shawng nnan e, kaja dik ai galaw shapraw ai lam hpe dawdan nna, ra ai tsi tsi ai lam a akyu hpe lu la na matu, ndai lawan ai lam hte maren, n-gun hpe gram lajang u.
Testing Method: Fix power hte tsan gang ai, lawan ai hku lawan ai hku jat wa ai, ra ai npu na n-gun (ga shadawn, 38 dynes) de du lu ai n-gun kaba dik htum hpe tam na matu dyne pen hte chyam yu u, dai gaw galaw shapraw ai atsam grau law ai shara re.
3. tsan gang ai lam – Tsi lajang ai lam a "Concentration"
Parameter Definition: Electrode hte corona tsi lajang ai lam lapran na gap hkat ai lam, shing nrai, electrode kaw nna arung arai ntsa de tsan ai shara (machine amyu hta hkan nna) lapran na gap hkat ai lam.
Tara:
Grai law hkra Long Disstance: Wan n-gun n-gun gaw n-gun yawm mat ai, corona hka pru ai lam ni gaw n-gun yawm mat ai, n-gun gaw arung arai ntsa hta hkrak hkrak n mai galaw ai, tsi lajang ai lam hpe shayawm ya lu ai.
Excessively Short Distance: Wan n-gun gaw grai tsaw ai, loi loi hte arc ni hpe sumla ka ai, sumla hkrung hpe jahten kau ai (sh) wan nat ai, electrodes hte dielectric layer ni hpe hkra machyi shangun ai, dai gaw grai hkrit tsang hpa rai nga ai.
Tuning Tips:
Ladat hpe hkan sa na Manual: Disance gaw shawng nnan na parameter rai nna, set galaw ngut ai hpang loi loi hte n mai galai shai ai. N bung ai jak amyu myu hte electrode hkrang ni gaw shanhte a myit mada da ai kaja dik htum gap ni nga ai (ga shadawn, 1.5-3.0mm).
Parallelism hpe kam hpa na: tsan ai shara hpe gram lajang ai shaloi, electrode hte roller ting a lapran na gap gaw tsep kawp bung ai hpe sadi ra ai; n rai yang, tsi tsi ai a akyu gaw maga mi de ngang kang nna, maga mi de gawng kya na re.
Fine a-Mungkan npawt tara: N-gun hte lawan ai lam hpe shadawn sharam de galai shai ai gaw ra kadawn ai lam ni hpe naw n lu galaw ai rai yang, galaw shapraw ai wa ahkang jaw da ai range kata na tsan gang ai lam hpe kaja ai-tuning galaw mai ai. Dai tsan ai shara hpe shayawm ai gaw tsi lajang ai lam hpe grai jat ya lu ai, raitim, nhtoi htoi ai hpe koi lu na matu grai sadi maja let galaw ra ai.
Test gaw lawan ai hpe jat wa ai hpang hkrat sum mat yang, shawng na lawan ai lam hpe bai gram lajang u (sh) n-gun hpe loi mi jat nna, n-gun nnan hpe hkap la lu na matu galaw u.
Ahkyak ai Note: Parameter langai hpra hpe galai shai ngut ai hpang, chyam dinglik ai lam garai n galaw shi yang, n yawm htum roll langai mi hpe lai na matu la nga u. Corona tsi lajang ai lam hta lag hte accumulation langai ngai nga ai majaw, kalang ta chyam dinglik ai a mahtai gaw n teng n man ai.
Kaga Common Factors ni gaw akyu hpe hkra machyi shangun ai
Material shi hkum nan: Masterbatch hte additives ni a shadawn shadang n bung ai ni (ga shadawn, slip agents) ni gaw tsi tsi ai lam a akyu hte aten shayawm ai lam hpe grai hkra machyi shangun ai.
Electrodes hte Dielectric Layers ni hpe san seng ai lam: Electrodes hte dielectric cover ni hpe ga yun, sau nsam, shing nrai oxides ni gaw grai sawng ai hku pat shingdang kau nna, tsa chyaru hte ayan san ra ai, etc.
Ambient Temperature hte Humidity: Nbung laru kaba ai gaw, hka lim ai atsam hpe hkra machyi shangun ai; workshop makau grup yin gaw loi mi sha ngang grin ra ai.
Aten dep galaw ngut ai hpang na tsi ladat: Corona tsi lajang ai a akyu gaw aten ladaw hte maren shayawm kau na re (grau nna slip agent ni lawm ai sumla hkrung ni a matu), laika dip ai (sh) lamination hpe tsi tsi ngut ai hpang hkying hkum 24 laman hta mai byin ai daram ngut kre hkra galaw ra ai.
Summary Rhyme: Shawng nnan e parallelism hpe hkam la lu na matu tsan ai shara hpe gram lajang nna, n-gun hpe gram lajang nna, n-gun hpe gram lajang u, dyne pen chyam dinglik ai hte jep yu u, fine{0}tune hpe margin hpe ngang grin hkra galaw u.
Ndai core parameters masum hpe hpaji masa hte jawm galaw ai hku nna, nang gaw n kaja ai corona tsi lajang ai lam a manghkang hpe teng sha hparan lu nna, n-gun ja ai{0}} manu dan ai hte hkrak hkra galaw lu ai.
