Abstract

In this study, the availability of PMDI resin for non-load bearing particleboard for use in humid conditions was investigated. For this purpose, PMDI resin was added to the middle layers of the boards at different participation rates (0% Control, 0.5, 0.75, 1, 1.5 and 2). Industrial chips used in particleboard production that it consists of 15% spruce, 50% pine, 20% oak, 10% slab, 5% sawdust. Particleboards were produced by using 65% melamine urea formaldehyde (MUF) resin with a density value of 630 kg / m3. Some physical (density, moisture, thickness swelling and water absorption for 2 and 24 hours) and mechanical properties of particleboards (bending strength, modulus of elasticity, internal bond, surface soundness and screw holding performance) were tested according to TS EN standards. According to the test results, thickness swelling values of the test boards for 24 hour were found to be below 14%. It was found that there was no statistically significant difference between all mechanical properties of the test and control boards except for screw holding performance. The values of all physical and mechanical properties of the boards indicated that they meet the minimum requirements in the P3 type (non load-bearing boards for use in humid conditions) specified in TS EN 312 (2012) standard.

Özet

Bu çalışmada, nemli şartlarda kullanılan ve yük taşıyıcı olmayan yongalevhalarda PMDI tutkalının kullanılabilirliği araştırılmıştır. Bu amaçla PMDI tutkalı, farklı katılım oranlarında (%0-Kontrol, 0.5, 0.75, 1, 1.5 ve 2) yongalevhaların orta tabakalarına ilave edilmiştir. Levha üretiminde kullanılan endüstriyel yongalar; %15 ladin, %50 çam, %20 meşe, %10 kapak tahtası, %5’i atık talaştan oluşmaktadır. Yoğunluk değeri 630 kg/m3 olan, %65’lik melamin üre formaldehit (MÜF) tutkalı kullanılarak yongalevhalar üretilmiştir. Levhaların bazı fiziksel (yoğunluk, rutubet, 2-24 saat kalınlık artımı ve su alma oranı) ve mekanik özellikleri (eğilme direnci, eğilmede elastikiyeti modülü, yapışma direnci, yüzey sağlamlığı ve vida tutma direnci) TS EN standartlarına göre test edilmiştir. Deney sonuçlarına göre test levhalarının 24 saatlik kalınlık artış değerleri, %14’ün altında tespit edilmiştir. Vida tutma direnci dışındaki tüm mekanik özellikler bakımından test ve kontrol levhaları arasında istatistiksel olarak anlamlı bir farkın olmadığı anlaşılmıştır. Levhaların tüm fiziksel ve mekanik özelliklerine ait değerleri, TS EN 312 (2012) standardında belirtilen P3 tipi (nemli şartlarda kullanılan yük taşıyıcı olmayan levhalar) kullanım alanlarında aranan minimum gereksinimleri karşıladığını göstermiştir.
