Abstract
Odun esaslı kompozit malzemeler içerisinde en önemli ürünlerden biri de liflevhalardır. Liflevhalar lignoselülozik yapıları sebebiyle kolay yanabilme ve tutuşabilme gibi bazı dezavantajlara sahiptir. Bu durum özellikle toplu yaşam alanlarında can ve mal güvenliğini tehdit edici bir unsurdur. Mobilya ve benzeri birçok odun esaslı malzemenin insan sağlığı ve güvenliği açısından yanmaya karşı daha dayanıklı hale getirilmesi önem teşkil etmektedir. Özellikle çeşitli kullanım yerlerinde yanmaya karşı belirli bir dirence sahip olan odun esaslı levha ürünleri zorunlu olarak tercih edilmektedir. Bu çalışmada; EcoChem (FR) (Flame Retardand Chemistry) ticari adıyla bilinen yanma geciktirici özelliğe sahip amonyum polifosfat (APP) ile üretilen orta yoğunlukta liflevhaların (MDF) yanma özellikleri incelenmiştir. Hem kontrol örnekleri hem de yanmaya karşı dayanıklı MDF’ler, laboratuar ortamında direk aleve maruz bırakılarak karşılaştırılmıştır. Ayrıca termogravimetrik analiz yöntemi ile de incelenmiştir. Sonuçta FR kimyasalı ile üretilen levhaların % 30 oranında yanmaya karşı daha fazla direnç gösterdiği gözlenmiştir.
One of the most important products in wood based composite materials is the fiberboard. The fiberboard has some disadvantages such as easy flammability and ignition due to its lignocellulosic structure. This situation is a threat to the security of life and property, especially in public areas. It is important to make furniture and many other wood based materials more resistant to burning in terms of human health and safety. In particular, wood-based sheet products having a certain resistance to combustion in various applications are necessarily preferred. In this study; The combustion properties of medium density fibers (MDF) produced by ammonium polyphosphate (APP), which is known as EcoChem (FR) (Flame Retardand Chemistry), were investigated. Both the control samples and the fire resistant MDFs were compared to the flame flame in the laboratory. It was also examined by thermogravimetric analysis method. As a result, it was observed that the panels produced with FR chemical showed 30% more resistance to combustion.
