JİPS ARTIĞINDAN TAGUCHİ YAKLAŞIMI KULLANILARAK ÇÖKTÜRÜLMÜŞ KALSİYUM KARBONAT (ÇKK) ÜRETİMİ

Bu çalışmada, desülfürizasyon ünitesinden elde edilen jips (DJ) taneciklerinin çöktürülmüş kalsiyum karbonat (ÇKK) taneciklerine direk mineral karbonatlaştırma yöntemi ile dönüştürülmesi sırasında ultrasonik güç uygulama, sıcaklık, karbondioksit (CO2) besleme hızı deneysel parametrelerinin etkileri Taguchi yaklaşımı kullanılarak araştırılmıştır. Deneylerde venturimetre ünitesi karbonatlaştırma zonu olarak kullanılmıştır. Elde edilen ürünlerin karakterizasyonu XRD, SEM ve tane boyutu analiz yöntemleri ile belirlenmiştir. Ayrıca ürünlerin özellikleri ASTM standartları dikkate alınarak değerlendirilmiştir. Sonuç olarak; üretim şartlarına bağlı olarak iğnemsi, kübik veya delikli yapıda kalsit kristallerinden oluşan ÇKK tanecikleri elde edilmiştir. ASTM standartlarına göre endüstriyel bir artıktan üretilen bu ürün, boya ve plastik sektörlerinde değerlendirilebilmesi için gereken özellikleri sağlamaktadır.
