DTF PET filmde \u0131s\u0131 b\u00fcz\u00fclmesi nedir?<\/h2>\n

Is\u0131 b\u00fcz\u00fclmesi, bir film numunesi \u0131s\u0131t\u0131ld\u0131ktan ve ard\u0131ndan belirtilen \u00f6l\u00e7\u00fcm ko\u015fuluna geri d\u00f6nd\u00fcr\u00fcld\u00fckten sonra kalan kal\u0131c\u0131 bir boyut de\u011fi\u015fikli\u011fidir. PET film, film \u00fcretimi, \u0131s\u0131l i\u015flem, kaplama, kurutma, dilimleme ve sarma i\u015flemlerinden kaynaklanan y\u00f6nelim ve art\u0131k gerilimler i\u00e7erebilir. Is\u0131tma, depolanan bu gerilimin bir k\u0131sm\u0131n\u0131 serbest b\u0131rakabilir ve boyutlar\u0131 de\u011fi\u015ftirebilir.<\/p>\n

Is\u0131tma s\u0131ras\u0131ndaki termal genle\u015fme, so\u011futma sonras\u0131ndaki art\u0131k \u0131s\u0131 b\u00fcz\u00fclmesiyle ayn\u0131 \u015fey de\u011fildir. Bir film s\u0131cakken genle\u015febilir ve orijinal boyutuna yak\u0131n bir de\u011fere geri d\u00f6nebilir veya d\u00f6ng\u00fcden sonra daha k\u00fc\u00e7\u00fck veya daha b\u00fcy\u00fck bir boyutu koruyabilir. Test, son \u00f6l\u00e7\u00fcm\u00fcn ne zaman al\u0131nd\u0131\u011f\u0131n\u0131 tan\u0131mlamal\u0131d\u0131r.

DTF film, sadece \u00e7\u0131plak PET'ten ziyade kaplamal\u0131 bir yap\u0131ya sahiptir. PET taban, yap\u0131sal deste\u011fin b\u00fcy\u00fck k\u0131sm\u0131n\u0131 sa\u011flarken, m\u00fcrekkep alan ve arka y\u00fczey i\u015flemleri gerilim dengesini, nem tepkisini, s\u00fcrt\u00fcnmeyi ve k\u0131vr\u0131lmay\u0131 etkileyebilir. Genel bak\u0131\u015f PET film kal\u0131nl\u0131\u011f\u0131 ve kaplama kalitesi<\/a> Bu yap\u0131y\u0131 a\u00e7\u0131klayan bu k\u0131lavuz, kal\u0131c\u0131 boyut de\u011fi\u015fiminin \u00f6l\u00e7\u00fclmesine odaklanmaktad\u0131r.<\/p>\n

Makine ve enine do\u011frultular neden \u00f6nemlidir?<\/h2>\n

Film, d\u00fczlem i\u00e7inde iki temel y\u00f6ne sahiptir. Makine y\u00f6n\u00fc (MD), \u00fcretim boyunca \u015feridin izledi\u011fi yolu takip eder. Enine y\u00f6n (TD) ise \u015feridin enine do\u011fru uzan\u0131r. \u00c7ift eksenli y\u00f6nlendirme, \u0131s\u0131l i\u015flem, kaplama gerilimi, sar\u0131m ve termal ge\u00e7mi\u015f, bu y\u00f6nleri farkl\u0131 \u015fekillerde etkileyebilir.<\/p>\n

Bu nedenle tek bir b\u00fcz\u00fclme de\u011feri \u00f6nemli bilgileri gizler. MD b\u00fcz\u00fclmesi daha b\u00fcy\u00fckse, bask\u0131 uzunlu\u011fu ve tekrar aral\u0131\u011f\u0131 besleme y\u00f6n\u00fcne ba\u011fl\u0131 olarak de\u011fi\u015febilir. TD b\u00fcz\u00fclmesi rulo boyunca farkl\u0131l\u0131k g\u00f6steriyorsa, bask\u0131 geni\u015fli\u011fi, kenarlar\u0131 ve d\u00fczl\u00fc\u011f\u00fc etkilenebilir. MD ve TD aras\u0131ndaki dengesizlik ayr\u0131ca \u00e7apraz bozulmaya veya k\u0131vr\u0131lmaya da katk\u0131da bulunabilir.<\/p>\n

Numuneyi kesmeden \u00f6nce MD ve TD'yi i\u015faretleyin. Rulodan k\u00fc\u00e7\u00fck bir numune \u00e7\u0131kar\u0131ld\u0131ktan sonra, g\u00f6rsel inceleme orijinal y\u00f6n\u00fcn\u00fc ortaya \u00e7\u0131karmayabilir. Y\u00f6n\u00fc numune koduna ve aktif \u00f6l\u00e7\u00fcm \u00e7izgilerinin d\u0131\u015f\u0131ndaki bir \u015femaya kaydedin.<\/p>\n

Hangi standart y\u00f6ntemler ge\u00e7erlidir?<\/h2>\n

ASTM D2732, se\u00e7ilen numune s\u0131cakl\u0131klar\u0131nda plastik film ve levhalar\u0131n k\u0131s\u0131tlanmam\u0131\u015f do\u011frusal termal b\u00fcz\u00fclmesini kapsar. ISO 11501 ise \u0131s\u0131tmadan sonra plastik film ve levhalar\u0131n boyuna ve enine y\u00f6nlerdeki boyutsal de\u011fi\u015fimini ele al\u0131r. Y\u00f6ntemler ayn\u0131 genel konuyu ele al\u0131r ancak teknik i\u00e7erikleri farkl\u0131d\u0131r, bu nedenle bir sat\u0131n alma sipari\u015finde referanslar\u0131 birbirinin yerine kullan\u0131labilir olarak ele almak yerine, gerekli y\u00f6ntemin ve s\u00fcr\u00fcm\u00fcn belirtilmesi gerekir.<\/p>\n

Bu, \u00fcretim kontrol\u00fc i\u00e7in faydal\u0131 olabilir, ancak y\u00f6ntem yine de kontroll\u00fc bir numune, s\u0131cakl\u0131k, s\u00fcre, destek, so\u011futma, \u00f6l\u00e7\u00fcm ve hesaplama gerektirir.
