Usability of Recycled Plastic Wastes for Particle Board Production as Construction Material

Abstract

The aim of this study is to examine important physical and mechanical properties of particle boards which were produced by adding plastic waste grinded to a certain particle size into wood shavings and using urea formaldehyde glue. The following values were obtained from the samples which were prepared to have different mixture proportions: unit weight was 684-966 kg/m3, thickness increment after a 24 hour water exposure was 1% -12%, the amount of water absorption was 21% -85%, bending strength was 5.20-17.94 MPa, perpendicular tensile strength was 0.15-1.32 MPa and heat conduction 0.128-0.160 W/mK. According to the results of the study, it was concluded that most of the characteristics of particle boards which are suggested under the related standards could be improved by reusing plastic waste for the production of particle boards, and that, in addition to this, negative environmental consequences caused by wastes could be minimized by utilizing plastic waste in this way.

Plastik Atıkların Yonga Levha Üretiminde Yapı Malzemesi Olarak Değerlendirilme Olanakları

Öz

Bu çalışmanın amacı, odun yongasına belirli büyüklüğe kadar öğütülmüş atık plastik ilavesiyle üre formaldehit tutkalı kullanılarak üretilen yonga levhaların önemli fiziksel ve mekanik özelliklerini incelemektir. Farklı karışım oranlarına sahip olmak üzere hazırlanan örneklerin, birim ağırlık değeri 684-966 kg/m3, 24 saat suda bekletme sonucu kalınlık artışı % 1-12, su emme miktarı % 21-85, eğilme direnci 5.20-17.94 MPa , yüzeye dik çekme direnci 0.15-1.32 kgf/cm2 ve ısı iletim katsayısı 0.28-0.160 W/mK olarak elde edilmiştir. Araştırma sonuçları; yonga levha üretiminde plastik atığın kullanımı ile yonga levhanın ilgili standartta öngörülen bir çok özelliğinin iyileştirilebileceği ve bunun yanında atık plastiklerin bu şekilde değerlendirilmesiyle olumsuz çevresel etkisinin azaltılabileceği kanısına varılmıştır.
