Abstract

The utilization and usage areas of the wood plastic composites (WPC) have increased over the years. In addition, the importance of wood plastic composites produced by adding pigments has increased in terms of usage area. To be able to increase the coating ability of plastics, different pre-treatment had been used and some improvements were achieved. It is the purpose of this study to determine the wear index in abrasion of the WPC with pigmented using various coating and pre-treatments. For this purpose, it was used 2 different coating types (acrylic and cellulosic based) and 4 different pretreatments (sanding, acid treatment, UV, microwave). WPC with pigmented were manufactured and samples after various pretreatment and coating were prepared. The adhesion strength values were determined after coating. The results showed that pre-treatments used in this project affected the wear index. Acrylic based coating gave the best results of wear index in abrasion

Effect of Pre-Treatments On Wear Index Of Varnished Wood Plastic Composites (Wpc) With Pigmented

Abstract

Ahşap plastik kompozitlerin (WPC) kullanım ve kullanım alanları yıllar içinde artmıştır. Ayrıca pigment ilavesiyle üretilen ahşap plastik kompozitlerin kullanım alanı açısından önemi artmıştır. Plastiklerin kaplama kabiliyetini artırabilmek için farklı ön işlemler kullanılmış ve bazı iyileştirmeler yapılmıştır. Bu çalışmanın amacı, çeşitli kaplama ve ön işlemler kullanılarak WPC'nin pigmentli aşınmasındaki aşınma indeksini belirlemektir. Bu amaçla 2 farklı kaplama tipi (akrilik ve selülozik esaslı) ve 4 farklı ön işlem (kumlama, asit muamelesi, UV, mikrodalga) kullanılmıştır. Pigmentli WPC üretildi ve çeşitli ön işlem ve kaplamalardan sonra numuneler hazırlandı. Kaplama sonrası yapışma mukavemeti değerleri belirlenmiştir. Sonuçlar, bu çalışmada kullanılan ön işlemlerin aşınma endeksini etkilediğini gösterdi. Akrilik esaslı kaplama, aşındırmada en iyi aşınma indeksi sonuçlarını vermiştir.
