Atık Ofis Kâğıtları Üzerinde Yapılan Mürekkep Giderme İşleminin Hamur Verimi ve Atık Çamur Üzerine Etkileri

Abstract

Bu çalışmada, atık ofis kâğıtları üzerine öncelikle siyah lazer baskı yapılmış ve daha sonra bu kâğıtlardan mürekkep giderme işlemleri gerçekleştirilmiştir. İkinci basamak olarak, baskılı kâğıtlar farklı şartlar altında Hobart hamurlaştırıcısı ile hamurlaştırılmış ve süspansiyonlar hazırlanmıştır. Hamurlaştırma ve süspansiyon hazırlama aşamalarında farklı oranlarda kimyasal ve enzimler katılmış ve bunların etkileri analiz edilmiştir. Ultrases etkisi de ayrıca incelenmiştir. Son olarak işlem görmüş olan atık kâğıt hamuru, yüzdürme esaslı mürekkep giderme işlemine alınarak mürekkeplerinden tamamen arındırılmaya çalışılmıştır. İşlem sonunda ise hamur ve atık çamur analizleri yapılmıştır. Bu sayede, test kâğıtlarında mukavemet değer kaybı olup olmadığına bakılmıştır. Çalışma sonunda, genel olarak test kâğıtlarında bir mukavemet artışı görülmüştür

In this study, firstly standart laser printing were applied on waste office papers and then deinking treatments were carried out on these papers. In the second step, printed papers were repulped using Hobart mixer under different conditions and the suspension were prepared. İn the stages of pulping and suspension preparetion, different level of chemicals and enzymes were added and their effects were analysed. The effect of ultrasound was also studied . In the final stage,the waste paper pulp treated was tried completely to purify from the deinks taking flotation deinking method. In the last of process, pulp and waste sludge were analysed. At this point, it was checked whether the lost of value strength on the test papers. At the end of the study, a strength increase was generally observed on the test papers
