\nTek bir \u00e7\u00f6z\u00fcc\u00fcn\u00fcn buharla\u015fma h\u0131z\u0131 fiziksel parametreleri taraf\u0131ndan belirlenirken, bask\u0131 m\u00fcrekkebi filmindeki \u00e7\u00f6z\u00fcc\u00fcler kar\u0131\u015f\u0131k \u00e7\u00f6z\u00fcc\u00fclerdir ve her \u00e7\u00f6z\u00fcc\u00fcn\u00fcn farkl\u0131 bir buharla\u015fma h\u0131z\u0131 vard\u0131r. Bu, karma\u015f\u0131k bir kimyasal kokteyl gibidir; u\u00e7uculu\u011fu y\u00fcksek bile\u015fenler \u00f6nce ka\u00e7arken, daha az u\u00e7ucu olanlar geride kal\u0131r ve \u00e7\u00f6z\u00fcc\u00fc bile\u015fiminde de\u011fi\u015fikliklere neden olur. Sabit bir s\u0131cakl\u0131kta sabit bir h\u0131zda buharla\u015fan tek bir \u00e7\u00f6z\u00fcc\u00fcn\u00fcn aksine, \u00e7\u00f6z\u00fcc\u00fc buharla\u015fma h\u0131z\u0131 kademeli olarak yava\u015flayacakt\u0131r. Solvent safl\u0131\u011f\u0131 standartlara uygun de\u011filse (\u00f6rne\u011fin \u00e7ok fazla y\u00fcksek kaynama noktal\u0131 bile\u015fen i\u00e7eriyorsa) veya yava\u015f kuruyan solventler a\u015f\u0131r\u0131 kullan\u0131l\u0131yorsa, normal ko\u015fullar alt\u0131nda ciddi kal\u0131nt\u0131 solvent sorunlar\u0131 ortaya \u00e7\u0131kacakt\u0131r. Bu nedenle, kar\u0131\u015f\u0131k \u00e7\u00f6z\u00fcc\u00fc form\u00fclasyonlar\u0131n\u0131n rasyonel tasar\u0131m\u0131 son derece \u00f6nemli bir teknik g\u00f6revdir ve ikame maddeler kullan\u0131l\u0131rken daha da dikkatli olunmal\u0131d\u0131r.
\nAyr\u0131ca, pigmentin y\u00fczey \u00f6zellikleri, spesifik y\u00fczey alan\u0131 ve konsantrasyonu da solvent buharla\u015fmas\u0131 \u00fczerinde etkilidir. Ayn\u0131 pigment i\u00e7in, solvent buharla\u015fma oran\u0131 artan pigment konsantrasyonu ile azal\u0131r; farkl\u0131 pigmentler i\u00e7in, genel olarak, solvent buharla\u015fma oran\u0131 d\u00fc\u015f\u00fck yo\u011funluklu ve k\u00fc\u00e7\u00fck partik\u00fcll\u00fc pigmentler i\u00e7in d\u00fc\u015f\u00fckt\u00fcr.
\n2. Kurutma ko\u015fullar\u0131
\nKurutma ko\u015fullar\u0131 aras\u0131nda kurutma havas\u0131 s\u0131cakl\u0131\u011f\u0131, hava hacmi (hava h\u0131z\u0131) ve kurutma cihaz\u0131n\u0131n yap\u0131s\u0131 yer al\u0131r. K\u00f6t\u00fc kurutma art\u0131k solvent miktar\u0131n\u0131 art\u0131racakt\u0131r. Hava s\u0131cakl\u0131\u011f\u0131n\u0131n ve hava hacminin (hava h\u0131z\u0131) artt\u0131r\u0131lmas\u0131 kurutma ko\u015fullar\u0131n\u0131 iyile\u015ftirebilir. Bununla birlikte, bas\u0131l\u0131 m\u00fcrekkep katman\u0131 kal\u0131nsa, \u00e7ok h\u0131zl\u0131 kurutman\u0131n m\u00fcrekkep katman\u0131 y\u00fczeyinin h\u0131zla bir film olu\u015fturmas\u0131na neden olaca\u011f\u0131 ve i\u00e7 \u00e7\u00f6z\u00fcc\u00fcn\u00fcn ka\u00e7mas\u0131n\u0131 \u00f6nleyece\u011fi unutulmamal\u0131d\u0131r. Bu bir araban\u0131n h\u0131zlanmas\u0131na benzer. \u0130yi kontrol edilmezse frenlerin bozulmas\u0131na neden olabilir.
\n3. Bask\u0131 h\u0131z\u0131
\nBask\u0131 h\u0131z\u0131, bas\u0131l\u0131 malzemenin kuruma s\u00fcresini belirler. Sadece bask\u0131 m\u00fcrekkebi tabakas\u0131 tamamen kurudu\u011funda bask\u0131 h\u0131z\u0131 art\u0131r\u0131labilir. Bu bir ko\u015fu yar\u0131\u015fmas\u0131 gibidir, \u00f6nce fiziksel g\u00fcc\u00fcn\u00fcz\u00fcn t\u00fcm s\u00fcreci destekleyebilece\u011finden emin olmal\u0131s\u0131n\u0131z ve sonra h\u0131zlanmay\u0131 d\u00fc\u015f\u00fcnebilirsiniz.
\n4. Kurutma ortam\u0131n\u0131n nemi (hava)
\nKurutma ortam\u0131n\u0131n (hava) nemi, art\u0131k solvent miktar\u0131 \u00fczerinde \u00f6nemli bir etkiye sahiptir. Bir yandan, m\u00fcrekkebe giren havadaki nem, solventin genel u\u00e7uculu\u011funu k\u00f6t\u00fcle\u015ftirirken; di\u011fer yandan, kurutma ortam\u0131nda b\u00fcy\u00fck miktarda nem bulunmas\u0131, solventin u\u00e7mas\u0131n\u0131 engelleyecektir. Ortam neminin iki kat\u0131na \u00e7\u0131kt\u0131\u011f\u0131 ya\u011fmur mevsimi boyunca, m\u00fcrekkebin kuruma h\u0131z\u0131 genellikle yakla\u015f\u0131k iki kat yava\u015flar. Bu nedenle plastik film \u00fczerine bask\u0131da yap\u0131\u015fma sorunlar\u0131 en \u00e7ok bu d\u00f6nemde ya\u015fan\u0131r. Bu nedenle, y\u00fcksek nemli ortamlarda, m\u00fcrekkep ile hava aras\u0131ndaki temas\u0131 azaltmak ve m\u00fcrekkebin tamamen kurumas\u0131n\u0131 sa\u011flamak i\u00e7in bask\u0131 h\u0131z\u0131 yava\u015flat\u0131lmal\u0131d\u0131r. Ayn\u0131 zamanda, bask\u0131 at\u00f6lyesindeki ba\u011f\u0131l nem genellikle 70%'yi ge\u00e7memelidir, ancak \u00e7ok kuru da olmamal\u0131d\u0131r, aksi takdirde statik elektrik sorunlar\u0131 ortaya \u00e7\u0131kabilir.
\n5. Alt tabaka filmi
\nFarkl\u0131 malzemelerden filmler solventler i\u00e7in farkl\u0131 se\u00e7ici emilim e\u011filimlerine sahiptir. Al\u00fcminyum folyo ve polyester gibi emici olmayan filmler genellikle daha az \u00e7\u00f6z\u00fcc\u00fc kal\u0131nt\u0131s\u0131na sahiptir; polipropilen filmler hidrokarbon \u00e7\u00f6z\u00fcc\u00fcleri tutma e\u011filimindeyken, emici filmler (naylon ve selofan gibi) alkol \u00e7\u00f6z\u00fcc\u00fcleri tutma e\u011filimindedir. Buna ek olarak, baz\u0131 filmlere eklenen katk\u0131 maddeleri de solvent buharla\u015fmas\u0131n\u0131 etkileyebilir ve b\u00f6ylece art\u0131k solvent miktar\u0131n\u0131 art\u0131rabilir.
\nKar\u015f\u0131 \u00f6nlemler: M\u00fcrekkepteki \u00e7\u00f6z\u00fcc\u00fclerin buharla\u015fma h\u0131z\u0131 sadece \u00e7\u00f6z\u00fcc\u00fcn\u00fcn kaynama noktas\u0131na, buhar bas\u0131nc\u0131na ve gizli buharla\u015fma \u0131s\u0131s\u0131na de\u011fil, ayn\u0131 zamanda \u00e7al\u0131\u015fma ortam\u0131n\u0131n s\u0131cakl\u0131\u011f\u0131na, nemine, hava hacmine, \u00e7\u00f6z\u00fcnen maddeye ve m\u00fcrekkep tabakas\u0131 kal\u0131nl\u0131\u011f\u0131na da ba\u011fl\u0131d\u0131r. Bu nedenle, m\u00fcrekkep i\u00e7indeki \u00e7\u00f6z\u00fcc\u00fclerin buharla\u015fma h\u0131z\u0131, ko\u015fullardaki de\u011fi\u015fikliklere g\u00f6re her an ayarlanmal\u0131d\u0131r. M\u00fcrekkep tabakas\u0131 normal s\u0131cakl\u0131klarda \u00e7ok h\u0131zl\u0131 kuruyorsa, buharla\u015fma h\u0131z\u0131 daha yava\u015f olan bir \u00e7\u00f6z\u00fcc\u00fc eklenebilir; de\u011filse, buharla\u015fma h\u0131z\u0131 daha h\u0131zl\u0131 olan bir \u00e7\u00f6z\u00fcc\u00fc eklenebilir. Ayr\u0131ca ksilen, etanol ve izopropanol kar\u0131\u015f\u0131m\u0131 bir \u00e7\u00f6z\u00fcc\u00fc ile seyreltilebilir (\u00fc\u00e7 \u00e7\u00f6z\u00fcc\u00fcn\u00fcn her biri 1\/3 oran\u0131nda kar\u0131\u015ft\u0131r\u0131l\u0131r ve kar\u0131\u015f\u0131k \u00e7\u00f6z\u00fcc\u00fc tek bir \u00e7\u00f6z\u00fcc\u00fcden daha etkilidir). \u00c7ok h\u0131zl\u0131 kurudu\u011funu d\u00fc\u015f\u00fcn\u00fcyorsan\u0131z, etanol\u00fcn bir k\u0131sm\u0131n\u0131 b\u00fctanol ile de\u011fi\u015ftirebilirsiniz (b\u00fctanol m\u00fcrekkebin parlakl\u0131\u011f\u0131n\u0131 art\u0131rabilir). Ancak, bas\u0131l\u0131 malzemenin kurumas\u0131n\u0131 etkilememek i\u00e7in eklenen miktara dikkat edin.
\nPlastik film \u00fczerine grav\u00fcr bask\u0131 i\u00e7in kullan\u0131lan \u00e7\u00f6z\u00fcc\u00fcler \u00e7o\u011funlukla alkollerdir ve benzenlerle desteklenir. Alkoller \u00e7o\u011funlukla etanol ve izopropanol, benzenler ise \u00e7o\u011funlukla toluen ve ksilen'dir. Nitrosel\u00fclozun ihtiya\u00e7lar\u0131 nedeniyle etil asetat ve butil asetat gibi esterler de eklenir. K\u0131sacas\u0131, m\u00fcrekkepteki organik \u00e7\u00f6z\u00fcc\u00fclerin sar\u0131mdan \u00f6nce tamamen buharla\u015fmas\u0131na izin verilmelidir.

\nBas\u0131l\u0131 m\u00fcrekkep katman\u0131n\u0131n yap\u0131\u015fmas\u0131, yap\u0131\u015fma ile yak\u0131ndan ilgilidir. Bas\u0131l\u0131 m\u00fcrekkep katman\u0131n\u0131n yap\u0131\u015fmas\u0131 zay\u0131f oldu\u011funda, bas\u0131n\u00e7 alt\u0131nda bas\u0131l\u0131 m\u00fcrekkep filmi kendisiyle temas eden ba\u015fka bir filme kolayca ge\u00e7erek yap\u0131\u015fmaya neden olabilir. Bu nedenle, iyi bir m\u00fcrekkep yap\u0131\u015fmas\u0131 sa\u011flamak \u00e7ok \u00f6nemlidir. Zay\u0131f m\u00fcrekkep yap\u0131\u015fmas\u0131n\u0131n nedenleri a\u015fa\u011f\u0131daki gibidir:
\n1. Yanl\u0131\u015f m\u00fcrekkep kullan\u0131lm\u0131\u015f veya farkl\u0131 m\u00fcrekkep t\u00fcrleri kar\u0131\u015ft\u0131r\u0131lm\u0131\u015f olabilir. Bu, yemek pi\u015firirken yeme\u011fin tad\u0131n\u0131 tamamen de\u011fi\u015ftirebilecek yanl\u0131\u015f baharat kullanmaya benzer.
\n2. Plastik filmin k\u00f6t\u00fc korona i\u015flemi g\u00f6rmesi veya a\u015f\u0131r\u0131 nem emmesi. Korona i\u015flemi film y\u00fczeyine \"y\u00fcz germe\" yapmak gibidir ve k\u00f6t\u00fc i\u015flem m\u00fcrekkep yap\u0131\u015fmas\u0131n\u0131 etkileyebilir.
\n3. Plastik filmdeki katk\u0131 maddeleri \u00e7\u00f6kelir veya hava, m\u00fcrekkebin yap\u0131\u015fmas\u0131n\u0131 etkileyen toz taraf\u0131ndan film \u00fczerine adsorbe edilir.

\n7. Film rulosu \u00fczerindeki bas\u0131n\u00e7 \u00e7ok y\u00fcksek. Film rulosu \u00fczerindeki a\u015f\u0131r\u0131 bas\u0131n\u00e7, m\u00fcrekkep tabakas\u0131n\u0131n temas y\u00fczeyine aktar\u0131lma e\u011filimini art\u0131racakt\u0131r. Film rulosunu dikey olarak saklamak, m\u00fcrekkep filmi ile temas y\u00fczeyi aras\u0131ndaki bas\u0131nc\u0131 etkili bir \u015fekilde azaltabilir.

\n4. Yap\u0131\u015fma hatalar\u0131na y\u00f6nelik \u00e7\u00f6z\u00fcmler ve \u00f6nlemler
\nYap\u0131\u015fmay\u0131 etkileyen \u00e7e\u015fitli fakt\u00f6rlerin analizi sayesinde, plastik grav\u00fcr bask\u0131daki yap\u0131\u015fma hatalar\u0131 i\u00e7in \u00e7\u00f6z\u00fcmleri ve \u00f6nlemleri \u00f6zetleyebiliriz.
\n1. Re\u00e7ineye katk\u0131 maddeleri eklemek, i\u00e7 yap\u0131\u015fmay\u0131 etkili bir \u015fekilde \u00f6nleyebilir ve iyi bir etkiye sahiptir. \u00d6rne\u011fin, oleik asit amid (kimyasal yap\u0131 C17H33CONH2, iyot de\u011feri \u2264 86g iyot \/ 100g, asit de\u011feri < 0.8mgKOH\/, erime noktas\u0131 72 - 76\u00b0C, beyaz veya sar\u0131 mumsu) kullan\u0131labilir. Kayd\u0131r\u0131c\u0131 bir maddedir. PE re\u00e7ineye eklenir ve yakla\u015f\u0131k 50\u00b0C s\u0131cakl\u0131kta vida ile kar\u0131\u015ft\u0131r\u0131l\u0131r. Erir ve plastik i\u00e7inde e\u015fit olarak da\u011f\u0131l\u0131r. Y\u00fcksek s\u0131cakl\u0131kta ekstr\u00fczyondan sonra, bir miktar oleik asit amid y\u00fczeye s\u0131zarak son derece ince bir mum filmi olu\u015fturur. Bu, film katmanlar\u0131n\u0131n do\u011frudan temas etmesini ve bir afinite olu\u015fturmas\u0131n\u0131 \u00f6nler, b\u00f6ylece yap\u0131\u015fmay\u0131 \u00f6nler.
\n\u00c7al\u0131\u015fma y\u00f6ntemi a\u015fa\u011f\u0131daki gibidir: \u0130lk olarak oleik asit amidi ezin, \u00e7\u00fcnk\u00fc gelen malzeme homojen olmayabilir ve ezilmemesi katk\u0131 maddesinin lokal olarak konsantre olmas\u0131na neden olur. Ezme i\u015fleminden sonra, kaba partik\u00fclleri gidermek i\u00e7in 50 g\u00f6zl\u00fc elekten ge\u00e7irin, AYPE peletlerine ekleyin ve 100 k\u0131s\u0131m re\u00e7ine ile 0,1 k\u0131s\u0131m oleik asit amid oran\u0131nda kar\u0131\u015ft\u0131r\u0131n. Basit bir kar\u0131\u015ft\u0131rmadan sonra, hazneye ekleyin ve proseste ba\u015fka hi\u00e7bir de\u011fi\u015fiklik yapmadan do\u011frudan kal\u0131ba \u00fcfleyin. Bunun \u00f6nemli bir etkisi vard\u0131r, sadece filmin i\u00e7 katmanlar\u0131n\u0131n birbirine yap\u0131\u015fmas\u0131n\u0131 \u00f6nlemekle kalmaz, ayn\u0131 zamanda film \u00fczerinde d\u00fczg\u00fcn, son derece ince bir balmumu tabakas\u0131 olu\u015fturur, bu da filmin y\u00fczeyini ve \u015feffafl\u0131\u011f\u0131n\u0131 b\u00fcy\u00fck \u00f6l\u00e7\u00fcde geli\u015ftirir. Grav\u00fcr bask\u0131dan sonra, m\u00fcrekkebin parlakl\u0131\u011f\u0131 \u00f6nemli \u00f6l\u00e7\u00fcde iyile\u015ftirilir ve m\u00fcrekkep al\u0131c\u0131l\u0131\u011f\u0131 \u00fczerinde herhangi bir etkisi yoktur. Bununla birlikte, dozaj 0.3%'yi a\u015ft\u0131\u011f\u0131nda, filmin y\u00fczey gerilimini kontrol etmek zordur ve m\u00fcrekkep al\u0131c\u0131l\u0131\u011f\u0131 azal\u0131r. Bu nedenle, dozaj 0.3%'nin alt\u0131nda kontrol edilmeli ve bas\u0131l\u0131 filmin y\u00fczey gerilimini 38\u00d710 - 5N\/cm\u00b2'nin \u00fczerinde kontrol etmek i\u00e7in \u015fi\u015firme kal\u0131plamadan sonra film korona i\u015flemine tabi tutulmal\u0131d\u0131r. Form\u00fcldeki i\u00e7erik 0.2% oldu\u011funda, viday\u0131 ve kal\u0131p kafas\u0131n\u0131 s\u00f6kmek ve temizlemek daha kolay olacakt\u0131r. Ayn\u0131 zamanda ya\u011flay\u0131c\u0131l\u0131\u011f\u0131 vida, kovan ve pafta ba\u015f\u0131 \u00fczerinde koruyucu bir etkiye sahiptir. Oleamid ayr\u0131ca plastiklerde belirli bir antistatik etkiye sahiptir. Renkli filmleri \u015fi\u015firirken oleamid eklemek renk da\u011f\u0131l\u0131m\u0131n\u0131 iyile\u015ftirebilir, renk masterbatchinin birikmesini \u00f6nleyebilir ve renk \u00fczerinde olumsuz bir etkisi yoktur. Ayr\u0131ca \u0131s\u0131l yap\u0131\u015ft\u0131rma torbalar\u0131 ve dilme ve kesme gibi i\u015flemler \u00fczerinde de etkisi yoktur.
\n2. Yava\u015f kuruyan solventlerin ve art\u0131k solventlerin kullan\u0131m\u0131n\u0131 kontrol edin. Yeterli \u0131s\u0131 ve hava hacmi sa\u011flayabildi\u011finden emin olmak i\u00e7in kurutma f\u0131r\u0131n\u0131n\u0131n performans\u0131n\u0131 en \u00fcst d\u00fczeye \u00e7\u0131kar\u0131n. So\u011futma silindirinin d\u00fczg\u00fcn bir \u015fekilde d\u00f6nd\u00fc\u011f\u00fcnden emin olun. Geri sararken, ka\u011f\u0131t t\u00fcp\u00fc ve silindirin kaymas\u0131ndan kaynaklanan anormal s\u0131cakl\u0131k art\u0131\u015f\u0131na dikkat edin. Bask\u0131 veya geri sarma denetimi s\u0131ras\u0131nda PET ve NY gibi ince filmlere \u00f6zellikle dikkat edin. Ta\u015f\u0131ma ve elle\u00e7leme s\u0131ras\u0131nda, d\u00fc\u015fmesini \u00f6nlemek ve film rulosu \u00fczerinde yap\u0131\u015fmas\u0131na neden olacak b\u00f6lgesel a\u015f\u0131r\u0131 bas\u0131nc\u0131 \u00f6nlemek i\u00e7in bask\u0131l\u0131 filmi dik olarak sar\u0131lm\u0131\u015f halde tutun. Bas\u0131l\u0131 desen belirli bir alanda yo\u011funla\u015fmamal\u0131d\u0131r. \u00c7ok renkli bask\u0131 i\u00e7in, desenin tasar\u0131m\u0131 \u00e7ok fazla renk \u00f6rt\u00fc\u015fmesi olmamas\u0131 gerekti\u011fi ger\u00e7e\u011fini dikkate almal\u0131d\u0131r. M\u00fcmk\u00fcnse, m\u00fcrekkep katman\u0131n\u0131n baz\u0131 alanlarda \u00e7ok kal\u0131n olmas\u0131n\u0131 \u00f6nlemek i\u00e7in spot renkli m\u00fcrekkep kullan\u0131labilir.
\n3. Plastik film \u00fczerindeki bask\u0131l\u0131 desen bir tarafa do\u011fru e\u011fimli ise, bask\u0131l\u0131 desenin oldu\u011fu taraf sarma s\u0131ras\u0131nda daha fazla bas\u0131n\u00e7 alt\u0131nda kalacakt\u0131r ve bu da kolayca yap\u0131\u015fmaya neden olabilir. Bu nedenle, bu t\u00fcr bir bask\u0131l\u0131 \u00fcr\u00fcn i\u00e7in, m\u00fcrekkep katman\u0131n\u0131n yap\u0131\u015fmas\u0131n\u0131 iyile\u015ftirmek i\u00e7in \u00f6nlemler al\u0131n\u0131rken \u00e7ok s\u0131k\u0131 sar\u0131lmamas\u0131na \u00f6zellikle dikkat edilmelidir. Plastik filmler \u00fczerine grav\u00fcr bask\u0131da, metal tozu i\u00e7eren m\u00fcrekkep tabakas\u0131 zay\u0131f kohezyona ve zay\u0131f yap\u0131\u015fmaya sahiptir ve \u00e7ok az bas\u0131n\u00e7 alt\u0131nda yap\u0131\u015fmaya neden olmak kolayd\u0131r.
\n4. Selofan, naylon veya her iki taraf\u0131 korona i\u015flemli filmler, sar\u0131mdan sonra arkadaki m\u00fcrekkep tabakas\u0131 ile g\u00fc\u00e7l\u00fc bir afiniteye sahiptir ve yap\u0131\u015fma riski y\u00fcksektir. Bu nedenle, bask\u0131dan \u00f6nce uygun kar\u015f\u0131 \u00f6nlemler al\u0131nmal\u0131d\u0131r. Yaln\u0131zca bir tarafa bask\u0131 yap\u0131l\u0131yorsa, korona i\u015flem cihaz\u0131 yaln\u0131zca bir taraf\u0131 i\u015flemden ge\u00e7irecek \u015fekilde ayarlanmal\u0131d\u0131r.
