Abstract

Bu bulus; degisik polimerlerin, özellikle poliesterin (Polietilen Tereftalat) ayni yönde dönen çift vidali vakumla vent edilen bir extruderin içerisinde "Ön Kurutma Yapilmadan Karistirilarak Eritilmesi" ve "Elyaf, Filament, Spunbonded ve Melt Blow Vatka, Film,pet sise preformu (isenin sisirilmeden önceki formu),pet sise ve plaka üretimi"hakkindadir. Farkli menseli poliesterlerin ve pet sise tiklarinin vakum altinda karistirilarak eritilmesi; eriyik içersindeki sudan kaynaklanan hidrolosis sonucu bozunmanin, dolayisi ile viskosite düsüsünün önlenmesi için sart olan "Ön Kurutma Islemini" ortadan kaldirmaktadir. Bu yöntemle; buhar,elektrik veya isitma yagi ile yapilan kurutma islemi ortadan kaldirilmakta ve önemli maliyet düsüsleri saglanmaktadir."Ayni Yönde Dönen Çift Vidali Vakumla Vent Edilen Extruderin" kullanilmasi; hammaddenin orjinal moleküller viskositesinin korunmasina, buna bagli olarakta elyaf üretim ve kaliplama performansina yardimci olmaktadir.This invention; "Melting by blending without pre-drying" and "Fiber, Filament, Spunbonded and Melt Blow Wadding, Film, pet fog preform (pre-wet form) of different polymers, especially polyester (Polyethylene Terephthalate) in a twin screw vacuum ventilator rotating in the same direction. , pet bottle and plate production ". Melting polyesters and pet mists ticks by mixing them under vacuum; It eliminates the "Pre-Drying Process" which is essential for the prevention of degradation due to hydrolosis caused by the water in the melt, and thus the viscosity drop. With this method; drying process with steam, electricity or heating oil is eliminated and significant cost reductions are provided. It helps to preserve the original molecules viscosity of the raw material, and accordingly, the fiber production and molding performance.
