Dyne Level Guide ku bujjanjabi bwa Corona, okukebera n'ebigendererwa

Okwanjula

Ebizibu ebisinga eby’okunyweza ebinenya yinki, okusiiga oba okusiiga mu butuufu bizibu by’amasoboza ag’okungulu. Firimu eva mu extruder ku 31 mN/m tejja kukwata yinki esinziira ku mazzi-ne bwe kinaaba kiteereddwa kitya.Obujjanjabi bwa Coronaeriwo okusitula amasoboza ago ag’okungulu okutuuka ku ddaala enkola y’omugga wansi ly’esobola okukwata, era engeri yokka eyesigika ey’okumanya oba yakola kwe kupima omutindo gwa dayini.

Ekitabo kino kinnyonnyola kiki ekipima omutindo gwa dyne, emiwendo ebigendererwa ku substrates eza bulijjo, engeri y’okugezesaamu mu butuufu, n’engeri y’okugonjoola obuzibu mu nkola y’okujjanjaba corona epima wansi okusinga bwe yandibadde. Kiwandiikiddwa abaddukanya emirimu, bayinginiya b’omutindo, n’abakyusa abeetaaga ennamba okusinga okukakasa.

Dyne Level Kiki Mubutuufu Kipima

Dyne level - mu ngeri entuufu, amasoboza ag’okungulu oba okusika kw’okufukirira - kunnyonnyola engeri amazzi gye ganaasaasaana ku ngulu enkalu. Kilagibwa mu mN/m (millinewtons per metre), nga mu kubala kifaanagana ne dyne/cm enkadde, kale ebigambo bino byombi bikozesebwa mu ngeri ekyusibwakyusibwa mu bimera ebisinga obungi.

Polyolefins ezitalongooseddwa tezirina-polar era nga zirina amasoboza ag’okungulu matono. Yinki, ekyesiiga n’okusiiga biba bya polar. Amasoboza ag’okungulu bwe gaba wansi okusinga okusika kw’amazzi ku ngulu, amazzi gafuuka obululu mu kifo ky’okusaasaana, era ekiyungo ekikola kiba kya makanika okusinga eky’eddagala - kinafu, era kitera okulemererwa mu nnimiro.

Lwaki Dyne Level Kikulu Okusinga Amaanyi g'Ekyuma

Abaguzi bulijjo balambika enkola y’okulongoosa corona nga bakozesa amaanyi agafuluma mu kilowatts era omuwendo ogwo bagutwala ng’ekikiikirira omulimu. Si bwe kiri. Omutindo gwa dayini ogutuukiddwako gusinziira ku kugatta obungi bw’amaanyi, ensengeka y’obusannyalazo, obudde bw’okubeera, ebbugumu ly’omukutu, obunnyogovu, n’ensengeka ya firimu yennyini.

Ebyuma bibiri ebipimiddwa ku maanyi ge gamu bisobola okutuusa emitendera gya dayini egy’enjawulo ennyo ku substrate emu. Ennyonyola enkulu ye ddaala lya dayini erituukibwako ku sipiidi ya layini eragiddwa ku firimu eragiddwa - so si kigero kya kilowatt ku lupapula lw’erinnya.

Emitendera gya Dyne egenderere okusinziira ku Substrate

Emiwendo gino wammanga bye biruubirirwa ebikola eby’omugaso eby’okupakinga n’okukyusa ebikozesebwa ebya bulijjo. Ebyetaago byawukana okusinziira ku yinki oba ekyesiiga ekigere, kale bulijjo kakasa n’omugabi wo awamu n’ebipimo wansi.

Substrate	Omutindo gwa dyne ogugendereddwamu ogwa bulijjo	Enkola eya bulijjo wansi w’omugga
LDPE / firimu ya LLDPE	38–42 mN/m	okukuba ebitabo mu ngeri ya flexo, lamination
Firimu ya HDPE	40–44 mN/m	ebiwandiiko, okupakinga
Firimu ya BOPP	38–42 mN/m	labels, okusiiga okusiiga
Firimu ya PET	44–50 mN/m	okufuula ebyuma, okusiiga
Firimu ya PVC	38–42 mN/m	shrink emikono
Ekipande kya aluminiyamu	38–44 mN/m	okusalako (lamination).

Amateeka abiri gagoberera okuva ku mmeeza eno. Ekisooka, okujjanjaba okusukkiridde-musango ddala: okusika PET waggulu nnyo wa 50 mN/m kiyinza okumenyaamenya kungulu ne kireeta okuzibikira oba okulemererwa kw’okusiba. Ekyokubiri, kwata ku kiruubirirwa, so si ku kigero ekisinga - ekigendererwa ddirisa lya nkola, so si nnamba ya likodi.

Engeri y'okugezesaamu Dyne Level

Enkola ez’omutindo nnyangu ate nga tezigula ssente nnyingi.ASTM D2578 nga bwe kiriekwata ku kugezesa okunyigirizibwa kw’okufukirira kwa firimu za polyethylene ne polypropylene, neISO 8296etegeeza enkola eyenkanankana ku firimu z’obuveera n’okusiba ebipande. Bombi beesigamye ku nkola y’emu: ssaako omuddirirwa gw’amazzi ag’okugezesa ag’okusika kw’okungulu okumanyiddwa era weetegereze ani agamala okufukirira kungulu mu kifo ky’okusiiga obululu.

Dyne pens y’enkola esinga okusimbula mu nnimiro, naye erina ekkomo. Ensonga y’ekkalaamu esobola okubeera encaafu, yinki esobola okukaddiwa, era ekivaamu kiba kya muntu yenna singa oyo akiddukanya aba mu bwangu. Ku kintu kyonna kasitoma-ekitunuulidde, kakasa n'ekibinja ekipya ekya yinki ez'okugezesa ku sampuli ennyonjo, era wandiika ebbugumu n'obunnyogovu mu kiseera ky'okupima.

Amateeka ag’omugaso ag’okusoma okwesigika:

• Gezesa oludda olujjanjabiddwa, era tokwata ku kifo we bakeberedde n’emikono egy’obwereere - amafuta g’olususu agasomebwa nga wansi ow’obulimba.
• Pima okubuna obugazi bw’omukutu, si mu layini ya wakati yokka.
• Gezesa mu ddakiika ntono ng’omaze okujjanjabwa ku layini, era nate ng’omaze okutereka olabe engeri omutindo gye guvunda.
• Kozesa ekifaananyi ekipya; sala sampuli ennyonjo okusinga okugezesa oludda olukutuse.
• Wandiika ennamba, substrate, sipiidi ya layini, n’olunaku.

Ebivudde mu Kusoma: Enkola eza bulijjo

Ennamba emu ekubuulira kitono. Omusono oguli ku mukutu gwonna gukugamba bingi.

Level correct mu makkati, wansi ku mbiriiziesonga ku kwambala kw’obusannyalazo, ekituli ku mabbali, oba obusannyalazo obutali bwenkanya-okukwatagana n’okuyiringisibwa.Level high ku ntandikwa y’okudduka n’okugwa okumala essaawaebiseera ebisinga kiraga okweyongera kw’ebbugumu ly’omukutu oba amasannyalaze agawuguka.Level correct ku line emu ate low ku ndala nga eddukanya film y’emueraga enjawulo mu nteekateeka y’ebyuma okusinga ekizibu ky’okukola.

Level correct amangu ddala nga omaze okujjanjabwa naye wansi nga roll esumuluddwa oluvannyuma lw’ennakuye kuvunda okwa bulijjo, era y’ensonga lwaki enkola y’okujjanjaba corona bulijjo erina okuteekebwa okumpi n’enkola eya wansi nga ensengeka bw’ekkiriza. Ku firimu ezimu, siteegi y’okuddamu-obujjanjabi nga bannamawulire tebannaba kuteeka ssente mu ngeri ya magezi okusinga okuba ey’ebbeeyi.

Okugonjoola ebizibu mu nkola y'okujjanjaba Corona

Kola ng’oyita mu kukebera kuno mu nsengeka ng’omutindo gwa dyne ogupimiddwa guli wansi w’ekiruubirirwa:

1. Sooka okakasizza ekipimo.Kebera emyaka gy’ekkalaamu, obukodyo bw’omukozi, n’obuyonjo bwa sampuli nga tonnakwata ku kyuma.
2. Kebera electrodes era ozingule.Obujama, okuzimba oxide-up, n’obusannyalazo obwambala bikendeeza nnyo ku bulungibwansi bw’obujjanjabi.
3. Kebera ekituli n’okukwatagana.Electrode-oku-roll clearance ne wrap angle okusalawo obudde bw'okubeera; ensobi entonotono ez’ebyuma zireeta okufiirwa okunene.
4. Kakasa nti amasannyalaze gafuluma.Tulansifooma oba jenereta eremereddwa esobola okufiirwa amaanyi agafuluma nga tewali kabonero konna kalabika.
5. Laba enkola ya firimu.Slip ne anti-block additives zisenguka ku ngulu ne ziziyiza obujjanjabi; resini ezzeemu okukolebwa eyinza okwetaaga ensengeka ez’enjawulo.
6. Kebera obutonde bw’ensi.Obunnyogovu obw’amaanyi n’ebbugumu ly’omukutu omutono byombi bikendeeza ku mutindo gwa dayini ogutuukiddwaako.

Okuwandiika ebivudde mu kukebera kuno kifuula ekyama ekiddirira ne kifuuka enkola ennyimpi era eddibwamu.

Okuddaabiriza n’okulabirira obusannyalazo

Enkola y’okujjanjaba corona tetera kulemererwa mangu. Kiwuguka, era okuwuguka tekulabika okutuusa ng’ekiyungo kiremye wansi w’omugga. Embeera ya obusannyalazo y’enkyukakyuka enkulu, era esaana enkola etegekeddwa okusinga okufaayo ng’obuzibu bulabika.

Okwoza obusannyalazo ku bbanga erigere - buli wiiki mu mbeera ezikyusa enfuufu, buli mwezi mu nnyonjo - ng’okozesa enkola n’ebizimbulukusa omukozi by’alaga. Oxide build-up n’enfuufu ya yinki ku electrode surface bikendeeza ku kifo ekikola obulungi eky’okujjanjaba, kale amaanyi gasigala nga gakyukakyuka ate corona treatment output egwa mu kasirise. Ensimbi z’omuzingo gw’ettaka zeetaaga okufaayo kwe kumu: omuzingo ogufuuse obucaafu gukyusa ekiziyiza kya dielectric era ne gukyusa ebivaamu okubuna omukutu.

Wandiika olunaku lw’okwoza, omutindo gwa dayini ogwapimibwa nga tonnaba n’oluvannyuma, n’okukyusakyusa kwonna okw’obusannyalazo. Mu myezi mitono log eyo ekubuulira ekiseera ekituufu eky’okukyusa layini yo, mu kifo ky’ekyo ekiri ku datasheet. Era kikuwa obujulizi kasitoma bw’abuuza lwaki batch yeeyisa mu ngeri ya njawulo: ensobi y’obujjanjabi bwa corona efulumira mu log kizibu ekigonjoddwa, ate ekirabika mu nnimiro yokka kiba kya butakkaanya.

Kuuma obusannyalazo bwa sipeeya, ekibinja kya yinki empya ez’okugezesa, n’enkola y’okupima erongooseddwa mu kifo. Ebiseera by’okuyimirira nga olinda electrode okutuuka bigula ssente nnyingi nnyo okusinga ekitundu ekyo.

Olukalala lw’okukebera ebikwata ku nsonga

Ebibuuzo ebibuuzibwa

Q1: Dyne level ennungi eri etya okukuba ku BOPP?

38–42 mN/m ye range eya bulijjo ekola ku BOPP nga tebannaba kukuba flexo oba okusiiga adhesive. Kakasa omuwendo omutuufu n'oyo akugaba yinki oba adhesive, okuva enkola ezisinziira ku solvent n'amazzi- bwe zaawukana.

Q2: Obujjanjabi bwa corona bumala bbanga ki?

Kivunda okumala ekiseera, kivunda mangu ku firimu ezimu ne mu kutereka mu bbugumu. Abakyusa bangi baluubirira okukozesa firimu erongooseddwa mu nnaku, era baddamu-okujjanjaba amangu ddala nga tebannaba kukuba mu kyapa olw'emirimu emikulu. Ekifo ekijjanjaba corona we kituula mu layini kikulu: gye kikoma okusemberera ekyuma ekikuba ebitabo, omutendera gye gukoma okukendeera nga tegunnakozesebwa.

Q3: Osobola okusukka-okujjanjaba firimu?

Yee. Emiwendo gya dayini egy’amaanyi ennyo giyinza okuvaako okuzibikira, okulemererwa kw’okusiba, n’okumenyaamenya kungulu, era ne bwonoona amaanyi. Laba ku ddirisa ly’ekigendererwa okusinga okubeera waggulu nga bwe kisoboka.

Q4: Njawulo ki eriwo wakati w’omutindo gwa dayini n’amasoboza ag’okungulu?

Bannyonnyola eby’obugagga bye bimu. Dyne/cm ne mN/m byenkana mu muwendo, era byombi biraga okusika omuguwa okw’okufukirira. Ebigambo byawukana wakati w’amakolero, so si fizikisi.

Q5: Omutindo ki ogukwata ku kukebera dyne?

ASTM D2578 ekwata ku kugezesa okunyigirizibwa kw’okufukirira kwa firimu za polyethylene ne polypropylene, ate ISO 8296 ekwata ku firimu z’obuveera n’ebipande. Zombi zeesigamiziddwa ku mazzi ag’okugezesa ag’okusika kw’okungulu okumanyiddwa.

Q6: Lwaki dyne level yange ekka ku mbiriizi z’omukutu?

Ebiseera ebisinga electrode okwambala, ekituli ekitali kyenkanyi, oba obugazi bw’obujjanjabi obutamala. Kebera embeera ya electrode n’okukwatagana kw’ebyuma nga tonnaba kwongera maanyi.

Q7: Obujjanjabi bwa corona busaanira ku aluminiyamu?

Yee, era ekozesebwa nnyo okulongoosa okunyweza nga tebannaba kugisiiga n’okugisiiga. Foyili yeetaaga okuddukanya obulungi ebbugumu kubanga etambuza bulungi ebbugumu, n’olwekyo ensengeka z’okulongoosa zaawukana ku firimu z’obuveera. Kakasa nti enkola y’okulongoosa corona eragiddwa ku bikozesebwa eby’ebyuma, okuva ensengeka za electrode ne roll bwe zitafaanagana.

Mu bufunzi

Dyne level ye kipimo yokka entuufu oba obujjanjabi bwa corona bukoze omulimu gwabwo. Teekawo ekiruubirirwa kya buli substrate, kigezese ne yinki empya ng’okozesa enkola ewandiikiddwa, laba engeri ennamba gye yeeyisaamu mu mukutu gwonna n’okumala ekiseera, era okuume ekyuma nga kiyonjo era nga kirimu ebituli ebituufu. Laba omutendera gwa dyne ng’ekitundu ky’okufuga okufulumya okusinga okugezesebwa okw’okukkiriza omulundi gumu-, era ensengeka y’obujjanjabi bwa corona ku nkomerero etegeeza ekintu ku dduuka mu kifo ky’okubeera ku satifikeeti. Pima ebyava mu bujjanjabi bwa corona ku nteekateeka era obujjanjabi bwa corona busigala nga buddibwamu, batch ku batch.

Shenzhen Hefengjiada Technology Co., Ltd. ekola enkola ezijjanjaba corona, eddagala erijjanjaba pulasima, ebyuma ebiyonja omukutu, n’ebiggyawo ebitali bikyuka (static eliminators) eby’ebikyusa firimu, foil, ne sheet, omuli n’ebifo ebifunda-web coronastations, wansi-ebiyimiridde ne kabineti-style corona generators, n’ensengeka ezigatta n’ewaniriddwa. Tuweereze substrate yo, line speed, ne dyne level eyeetaagisa, era ttiimu yaffe ejja kulambika enkola entuufu era ejja kuwagira okugezesebwa kwo okw’okukkiriza.
