Description

TARIFNAME FIBC ASTAR FILMI Bulus bir poliolefin homopolimeri veya kopolimeri, erime noktasi 100°C ve 120°C arasinda olan bir polieter kopolimeri ve oksijen bariyeri olusturan polimer ihtiva eden bir tabaka içeren, kalinligi tercihen 50 ila 300 mikron olan plastik filme iliskindir. BILINEN HUSUSLAR Plastik kaplar "gida ambalaj lari" gibi ambalaj lama uygulamalarinda giderek daha fazla kullanilmaktadir. Dökme gida (örnegin toz halinde gida, kahve, kakao, kabuklu yemis) ambalaj lamasinda siklikla kullanilan tipik bir plastik kap FIBC (= esnek ara dökme yük kabi) olarak adlandirilir. Bu tip kap genellikle bir dokuma polietilen veya polipropilendir. Dokuma malzemenin içinde veya disinda siklikla baska bir plastik astar kullanilir. Bu astar tek bir tabaka veya birden fazla tabakadir ve polimer malzemeleri içerir. US 6,3 74,579"da gösterildigi gibi bu astarin dis dokuma astara farkli yapisma biçimleri vardir. Birden fazla tabaka kullanildiginda, farkli tabakalar, nihai uygulamalar için farkli avantajlar saglar. Iç tabaka (= paketlenmis gidayla direkt temas eden tabaka) çogunlukla çok iyi sizdirmazlik saglamak üzere formüle edilir, böylece paketlenmis ürün için zararli olacak sizmalara karsi koruma saglar. Baska tabakalar, malzemenin mekanik direncini arttirmak için kötü kullanima dayanikli polimerler içerebilir. Oksijene duyarli gida maddeleri söz konusu oldugunda, çok tabakali konstrüksiyonun en azindan bir tabakasi oksijen geçirmeyen malzeme içerir. Bu alanda iyi bilindigi gibi, bu malzemeler örnegin poliamidler PVDC veya EVOH°tur. Çogunlukla çok tabakali film "körüklü boru" konfigürasyonundadir. Bunun nedeni bu konfigürasyonun dökme ürün doldurma, tasima ve bosaltma için bir basit boru konfigürasyonuna göre daha pratik olmasidir. Körükler, filmin izledigi iki "kirma konstrüksiyonu" (çogunlukla ahsap veya metal levhalar) kullanilarak islem sirasinda üretilir. Bu çok tabakali boru seklindeki malzemeler çogunlukla, katlanan çerçeve-sikistirma silindiri bölümünün döndürülmesini içeren "sicak üfleme film" usulüyle üretildigi için, genel bir problem dönmenin ardindan sürekli veya periyodik olarak kirismalar olmasidir ve bu kirpintiyi arttirir ve islem verimliligini azaltir. Kirismalarin boru seklindeki filmin körüklü bir boru haline getirilemeyecegi kadar sik oldugu durumlar vardir. Bu alanda, daha az sert polimerlerde, örnegin LDPE,de, HDPE gibi daha sert polimerlere göre daha iyi körük olusturulabildigi bilinmektedir. Üretim islemi sirasinda etkili bir sekilde bir körük olusturmak için malzemenin daha yumusak ve daha katlanabilir olmasi gerektigine inanilmaktadir. EVOH veya poliamid gibi oksijen bariyeri özellikleri iyi olan bariyer malzemeleri, poliolefinlerden genellikle daha sert olduklari için körük olusturma islemini daha da güçlestirmektedir. Patent basvurusu EP 3 216 599 A1"de filmin en az bir tabakasinda poliolefinlerle karisim halinde bir polieter kopolimeri (poliamidle veya poliolefinlerle) kullanarak körük olusturmayi kolaylastirmanin bir yolu açiklanmaktadir. Bu bulusun sakincasi, yapisma sicakliklarinin 140°C ila 160°C,de, yani polietilen gibi saf poliolefinlerinkinden yüksek sicakliklarda baslamasidir. Normal polietilen, bariyersiz astarlarla ayni veya benzer kosullarda astarlar üretmek için, yapisma sicakligi "pencere"sinin daha düsük sicakliklara, örnegin 120°C,ye indirilmesi gerekmektedir. Plastik yapisinin körüklü hale getirilmesinin kolaylastirilmasina, yani plastik filmin oksijen bariyeri özelliklerinden fedakarlik etmeden, yaygin olarak kullanilan 50-300 mikron araligindaki kalinlikta hiç kirisma olmaksizin körükler olusturmak için yeterli katlanabilirlige ve yeterli kabarcik stabilitesine sahip malzemelerin bulunmasina ihtiyaç vardir. Ayrica körüklü hale getirilebilirlikteki bu artisin düsük sicakliklarda yapistirmada yukaridaki gerekliliklerle kombine edilmesine ihtiyaç vardir. BULUSUN ÖZETI Poliolefinlerle karisimlara erime noktasi 100°C ila 120°C olan polieter kopolimerlerinin ilave edilmesinin, oksijen bariyeri saglayan plastik filmlerdeki körük olusturulabilirligi çok arttirdigi ve ayni zamanda filmin yapismaya baslama sicakligini 120°Csye düsürdügü beklenmedik bir sekilde tespit edildi.

Film katlanip bükülen çerçevenin bütün dönüsü sirasinda islem sirasinda herhangi bir kirisma olmadan mükemmel bir sekilde körüklü bir boruya dönüsmektedir. Tercihen iç tabakaya erime noktasi 100°C ila 120°C olan polieter kopolimerleri agirlikça %5 ila %20 araligindaki bir miktarda ilave edilir. Tercih edilen polieter kopolimerleri, poliolefinler, poliamidler veya poliesterler kopolimerlerdir. Bulus için yararli olan bir polieter kopolimerinin tipik bir örnegi Sanyo Chemical°dan Pelestat LM230,dur. Tercih edilen bir düzenlemede, polieter kopolimerlerinin erime noktalari 100°C ila 120°C, tercihen 110°C ila 120°C araligindadir. Erime noktasi daha düsükse, polimer yapiskanligina bagli olarak daha yüksek sürtünmeyle körük olusturulabilirlik azalir, erime sicakliklari daha yüksek oldugunda ise yapismaya baslama sicakligi artar. Polieter kopolimerinin tercih edilen eriyik akis indeksi (MFI) ASTM D 1238,e göre ölçüldügünde 190°C,de ve 21.18 N,de 12,nin üzerindedir. YAPISMAYA BASLAMA SICAKLIGI Bu terim bu basvuruda, yapistirma süresi 2 saniye, yapistirma basinci 4 bar ve yapistirma istasyonu darbeli tipte oldugunda ortalama yapisma kuvvetinin (ASTM F88,e göre ölçülür) en az 25N/ 15 mm yapisma genisligi olmasina izin veren düsük yapisma sicakligi olarak tanimlanmaktadir. Bu bulusun filmlerinde yapismaya baslama sicakligi 130°C,nin altinda, POLIETER KOPOLIMERININ ERIME NOKTASI Polieter kopolimerinin erime noktasi bu alanda iyi bilindigi gibi DSC"yle (=diferansiyel tarama kalorimetrisi) ölçülür. Bu bulusta kullanilan polieter kopolimerinin erime noktasi 100°C ile 120°C arasindadir. Bu bulusun filmini üretmek için tercih edilen usul bu alanda iyi bilindigi gibi sicak üfleme film usulüdür. ÖRNEKLER Ticari bir sicak üfleme film hattindan asagidaki filmi ürettik: * Dis tabaka, kalinlik 30 mikron * Ara tabaka 1, kalinlik 10 mikron * Baglayici tabaka 1, kalinlik 8 mikron * EVOH %38, kalinlik 8 mikron * Baglayici tabaka 2, kalinlik 8 mikron *Ara tabaka 2, kalinlik 20 mikron *Iç tabaka, kalinlik 12 mikron. Dis tabaka asagidakilerin bir karisimiydi: Ara tabaka l asagidakilerin bir karisimiydi: LDPE dis tabakada kullanilanla ayniydi. Baglayici tabaka 1 maleik anhidrür LLDPE bazli kopolimerdi. Balayici tabaka 2, baglayici tabaka l,e benzerdi. Ara tabaka 2 ara tabaka 1,in tamamen aynisiydi. Iç tabaka asagidakilerin bir karisimiydi: Kullanilan polieter kopolimeri Sanyo ChemicaFdan Pelestat LM230,du. Örnek 2,de, dis tabakada kullanilan LDPE,nin yerini ara tabaka 1"de kullanilan etilen heksen kopolimeri aldi. Bu örnekte EVOH %38 yerine daha sert olan ve körük olusturmanin daha güç oldugu düsünülen %32 kullanildi. KARSILASTIRMALI ÖRNEK Karsilastirmali örnek, örnek l,e benzerdi, ama polieter kopolimeri kullanilmayip onun yerine MV PEBAX 1074 SAOl kullanildi. Bu malzemenin erime noktasi diferansiyel tarama kalorimetrisiyle (DSC) ölçüldügünde 158°C"dir. INCELEME SISTEMI Üfleme film hattinin kulesi üzerine bu alanda bilindigi gibi iki körük levhasi monte edildi. Her örnek yapi 2 saat üretimde tutuldu ve kirisma sayisi izlendi. Kirismalar vakitli araliklarla ortaya çikma egilimi gösterdigi için, "kirisma vakalarini" kaydettik, yani 3,ten fazla kirisinanin üfleme film hattinin sikistirma bölümünden geçtigi her vakayi kaydettik. Dönme hizi bütün deneyler sirasinda sabit tutuldu. SONUÇLAR Örnek 1 ve 2,de 2 vaka, örnek 3,te ise 3 vaka kaydedildi. Karsilastirmali örnekte 2 vaka kaydedildi. Dolayisiyla, bulus önceki teknigin iyi körük olusturulabilirligini korumaktadir. YAPISMAYA BASLAMA Yapismaya baslama testi bir Toss yapistirma makinesinde, yapistirma süresi 2 saniye ve yapistirma basinci 4 barda tutularak yapildi. Yapistinnada iç taraf iç tarafa yapistirildi. Örnek 1,in ölçülen yapismaya baslama sicakliginin 120°C oldugu tespit edildi, karsilastirmali örnek içinse yapismaya baslama sicakligi 170°C olarak ölçüldü. TR
