Bu çalışmada, MDF levhaların yangına dayanıklılık özelliklerini arttırmak için kalsit mineralinin MDF üretiminde kullanılma imkanları araştırılmıştır. Yongalar Asplund defibratörde 4 dakika 7.5 bar ve 180ºC sıcaklıkta pişirilmiştir. liflemeden önce % 1,5 sıvı parafin mantarlaşmış yongalara verilmiştir. 1 m³ MDF üretimi için kullanılan lignoselülozik liflerin yerine; %3, %6, %9 oranlarında kalsit minerali üre formaldehite tutkalı ile karıştırılarak blowlinedan liflere verilmiştir. Lifler % 12 rutubete kadar kurutulmuştur. Levhalar 185 °C sıcaklık, 32 kg/cm² basınç ve 270 saniyede sekiz katlı sıcak preste preslenmiştir. Üretilen levhalar 50, 80 ve 120 tane büyüklüğünde zımpara bantları ile zımparalanmıştır. Kalsit katkılı üretilen levhaların yanma testleri; AKY, KKY, KHY, AKY lüks, KKY lüks, KHY lüks, İYB, KHYS, Ağırlık kaybı deneyleri yapılmıştır. Sonuç olarak kalsit mineralleri; levhaların yangına karşı direnç testinde iyi bir performans göstermiştir.

In this study, in order to increase the fire resistance properties of MDF boards, the possibilities of using calcite mineral in MDF production were investigated. Wood chips were cooked 4 minutes, 7.5 bar, and 180ºC temperature in Asplund defibrator. Instead of lignocellulosic fibers used for the production of 1 m³ MDF, 1.5% liquid paraffin before fibrillation later hardener, 3%, 6%, 9% urea-formaldehyde and calcite mix solutions were added on fibers in blowline, respectively. The fibers were dried to 12% moisture by dryer. Boards were produced 185°C temperature, 32 kg/cm² pressure and 270 second pressing time by multi-day eight-layer hot press. Boards were sanded by 50, 80 and 120 grit size sanding belts. MDF Combustion tests; FIC, SC, ESC, FIC lux, SC lux, ESC lux, IST, ESCS and weight loss tests were carried out. Consequently, calcite minerals have increased the resistance to fire of MDF as good performance.
