Abstract:

 Almond kernel, with a continuously increasing consumption, and is also important for our country, is a valuable agricultural product. Its production yields the hard shell as a by-product. The shell and the kernel have approximately the same weight. However, the shell is usually burned, or occasionally ground for use in the cosmetic industry or filters. Almond shell is a porous, hard, lignocellulosic, and a renewable resource. Particleboard industry is considered for sustainable, higher value-added, and environmentally lower-impact use of this resource. For this purpose, a detailed literature review was conducted, and the reviewed studies were compiled and summarized. The literature review reveals numerous studies on the re-evaluation of shells of hard-shell nuts as materials for various industrial sectors. However, studies on almond shells are limited in number. After the literature review and conceptualization stages, particleboards with different densities and almond shell contents were produced using almond shell particles. The thermal conductivities of the boards were determined experimentally. The thermal conductivity value increases with the increase in board density. The almond shell content, however, exhibits different effects depending on the board densities. The smallest thermal conductivity value obtained in the study was 0.07 WmK, while the highest value was found to be 0.19 WmK. Although the study was conducted with a constant temperature difference, the thermal conductivity value increases with increasing temperature values.

 Badem meyvesi, tüketimi sürekli artan, ülkemiz için de öneme haiz, değerli bir tarım ürünüdür. Üç katmanından dıştaki insanlar tarafından tüketilmez ve başka endüstrilerde kullanılmaktadır. Kalan iki katman çekirdeği oluşturur. Çekirdeğin kabuğu ile içi neredeyse aynı ağırlığa sahiptir. İç kısım insanlar için değerli bir yemişken kabuk genellikle yakılarak, nadiren de öğütülerek kozmetik sektöründe veya filtrelerde kullanılmaktadır. Badem kabuğu gözenekli ve sert, lignoselülozik, yenilenebilir bir kaynaktır. Bu kaynağa sürdürülebilir, daha yüksek katma değer oluşturan, çevre etkisi daha düşük bir kullanım için yonga levha endüstrisi düşünülmüştür. Bu amaçla detaylı bir literatür taraması yapılmış ve akabinde badem kabuğu parçacıkları kullanılarak yonga levhalar üretilmiştir. Badem kabuğu parçacıklarının yonga levha içerisindeki ağırlıkça farklı oranları ile bir üretim seti oluşturulmuş, daha sonra levhaların yoğunluk değişiminin incelenebilmesi için farklı yoğunluklarda ikinci bir üretim yapılmıştır. Levhaların ısıl iletkenlikleri deneysel olarak belirlenmiştir. Levha yoğunluğu artışı ile ısıl iletkenlik değeri artmaktadır. Badem kabuğu oranı ise levha yoğunluklarına bağlı olarak farklı etkiler göstermektedir. Çalışmada en küçük ısıl iletkenlik değeri 0,07 WmK olarak elde edilirken en yüksek değer 0,19 WmK olarak bulunmuştur. Çalışma sabit sıcaklık farkı ile gerçekleştirilmesine rağmen sıcaklık değerlerindeki artışa bağlı olarak ısıl iletkenlik değeri artmaktadır. En düşük ısıl iletkenlik 0,6 gcm3 ve 60 badem kabuğu katkılı levha için elde edilmiştir.
