Abstract

Çalışmanın amacı: İnorganik kaya tuzunun MDF üretiminde kullanılabilirliliğini araştırmaktır.
Çalışma alanı: Malzemeler sırasıyla Çankırı yöresinden kaya tuzu, Batı Karadeniz bölgesinden odun toplanmıştır. Üretim Düzce'de özel bir firmada gerçekleştirildi. Testler Düzce Orman Fakültesi Laboratuvarı ve Gazi Ağaç İşleme Endüstri Mühendisliği Laboratuvarından yapılmıştır.
Materyal ve yöntem: Asplund Defibrator'da cipsler 7-7.5 bar buhar basıncında, 180°C sıcaklıkta 4-5 dakika pişirilmiştir. Kuru lif ağırlığına göre liflendirmeden öncesi% 1.5 parafin, liflendirmeden sonra % 1 amonyum sülfat solüsyonu verildi.. 1m³ MDF üretiminde lignoselülozik liflerin yerine; inorganik dolgu minerali kaya tuzu kullanmak için ayrı bir tankta hazırlanmıştır. Üre formaldehit tutkalı ile birlikte sırasıyla % 3 (20 kg), % 6 (40 kg), % 9 (60 kg) kaya tuzu solusyonu liflere blow line hattında verilmiştir. Lifler pasta haline getirildikten sonra sıcak preste 185-190°C sıcaklık, 32-34 kg/cm² basınç uygulanarak ve 270 saniyede levhalar üretilmiştir. Presleme sonrasında MDF paneller (2100x4900x18 mm) ölçülerinde üretilmiştir. Fiziksel, mekanik ve yanma testleri gerçekleştirilmiştir.
Temel sonuçlar: Yüzde 3 kaya tuzu katkılı MDF ürünleri bu çalışmadaki diğer MDF panellerinden daha iyi performansa sahiptir.
Araştırma vurguları: Kaya tuzunun yüzde 3 oran ile MDF üretiminde kullanımı önerilir.

The Utilizing Rock Salt of Inorganic Filler in Medium Density Fibreboard (MDF) Production

Abstract

Aim of study: To research the usage opportunities of the inorganic rock salt mineral in MDF production.
Area of study: The materials were collected rock salt from Çankırı region, wood from the Western Black Sea region, respectively. The production was performed in a private company in Düzce. The tests were performed at Duzce Forest Faculty Laboratory and Gazi Woodworking Industrial Engineering Laboratory.
Material and methods: In the Asplund Defibrator, chips were baked wtihin 7-7.5 bar vapor pressure and 180 ° C temperature for 4-5 minutes. According to the weight of dry fiber, 1.5% paraffin was given before fibrillation, fibrillation later was given 1% ammonium sulfate solution. Inorganic fillers prepared in a separate tank in order to use rock salt instead of lignocellulosic fibers in the production of 1 m³ MDF. After that urea-formaldehyde glue is prepared as three different solutions which include the rock salt respectively with 3% (20 kg), 6% (40 kg), 9% (60 kg). This press applies 185-190 °C temperature and 32-34 kg/cm² pressure to the mixture material in 270 second pressing time. MDF panels (2100x4900x18 mm) were produced in the process. Physical, mechanical and combustion tests experiments are performed over boards.
Main results: MDF products which were added per cent 3 with the rock salt have more performance than the other MDF panels in this study.
Highlights: The usage of the rock salt with per cent 3 is recommended in MDF products.
