Abstract

Wood flour is the most common filler used in the production of wood plastic composite (WPC) materials. In scientific studies on this subject, wood flours obtained from different trees and fillers obtained from different annual plants are used. In addition, some mineral-based fillers are also used in materials made of plastic. In this study, a low-density polyethylene polymer obtained from recycling was used as the matrix. Larch wood flour and glass flour obtained by grinding soft drink bottles were used as fillers. Composite boards were produced using 60% polymer as the matrix, along with wood flour and glass flour in varying proportions. The density, flexural strength, flexural modulus, tensile strength, tensile modulus, elongation at break, and hardness values of the produced composites were determined. Based on the data obtained, the density increased with the addition of wood flour and glass flour as fillers, and the density-increasing effect of the glass flour was higher than that of the wood flour. Compared to the control samples, it was determined that the bending strength and elongation at break of the experimental groups decreased, and the flexural modulus and tensile modulus increased in the experimental samples using wood flour and glass flour.

Polietilen, odun unu ve cam unu ile üretilen odun plastik kompozit malzemelerin bazı özellikleri üzerine karşılaştırmalı bir çalışma

Abstract

Odun plastik kompozit (OPK) malzemelerin üretiminde dolgu maddesi olarak çoğunlukla odun unu kullanılmaktadır. Bu konuda yapılan bilimsel çalışmalarda da farklı ağaçlardan elde edilen odun unları ve değişik yıllık bitkilerden elde edilen dolgu maddeleri kullanılmaktadır. Ayrıca, bazı mineral esaslı dolgu maddeleri de plastikten üretilen malzemelerde kullanılmaktadır. Bu çalışmada, geri dönüşümden elde edilen düşük yoğunluklu polietilen polimer matris olarak kullanılmıştır. Dolgu maddesi olarak Karaçam odun unu ve kullanılmış meşrubat şişelerinin öğütülmesi ile elde edilen cam unu kullanılmıştır. Kompozit levhalarda polimer matris %60 oranında ve odun unu ve cam unu ise değişen oranlarda kullanılmıştır. Üretilen kompozitlerin; yoğunluk, eğilme direnci, eğilmede elastikiyet modülü, çekme direnci, çekmede elastikiyet modülü, kopmada uzama ve Shore D sertlik değerleri belirlenmiştir. Elde edilen verilere göre; odun unu ve cam ununun dolgu maddesi olarak eklenmesi ile yoğunluğun arttığı ve cam ununun yoğunluğu artırıcı etkisinin daha fazla olduğu belirlenmiştir. Kontrol örneklerine kıyasla, odun unu ve cam ununun kullanıldığı deney örneklerinde, eğilme direncinin ve kopmada uzama miktarının azaldığı, eğilmede ve çekmede elastikiyet modülünün artığı belirlenmiştir.
