Evaluation of furniture industry wastes in polymer composite production

Abstract

In this study, composite materials were produced by adding medium density fiberboard (MDF) waste and massive timber waste from furniture industry into PVC polymer matrix at different ratios. For the production of PVC composite materials, each waste material was mixed with PVC polymer and then, they were converted into pellets using twin screw extruder and combined pelletizer. The obtained pellets were molded into composite boards in 250 x 250 x 2 mm dimensions via hot press molding technique. The mechanical properties of the produced composites were compared with each other and with pure PVC based board in order to determine whether they can be used in various applications. The result of the mechanical tests showed that the tensile strength value of 10% wood flour-added PVC composites had the highest tensile strength value of 24.51 MPa. On the other hand, the highest bending strength value of 61.20 MPa was found for composite material with 10% MDF powder.

Mobilya endüstrisi atıklarının polimer kompozit üretiminde değerlendirilmesi

Abstract

Bu çalışmada, PVC polimer matrisi ile mobilya endüstrisi atıklarından orta yoğunluklu lif levha (MDF) ve masif kereste atıkları kullanılarak kompozit malzemeler üretilmiştir. Kompozit malzemelerin üretimi için her bir atık malzeme PVC polimeri ile çift vidalı bir ekstruder ve peletleyici kullanılarak pelet haline getirilmiştir. Elde edilen pelletler, sıcak pres kalıplama tekniği ile 250x250x2 mm boyutlarında kompozit levhalar haline getirilmiştir. Kompozitlerin çeşitli uygulamalarda kullanılıp kullanılamayacaklarını belirlemek için yapılan testler ile elde edilen kompozitlerin birbirleriyle ve saf PVC ile mekanik özellikleri karşılaştırılmıştır. Mekanik testlerin sonucu %10 odun unu katkılı PVC kompozitlerin çekme mukavemeti değerinin 24.51 MPa ile en yüksek çekme dayanım değerine sahip olduğunu göstermiştir. Öte yandan en yüksek eğilme direnci değeri, %10 MDF tozu katkılı kompozit malzemede 61.20 MPa bulunmuştur.
