Fosfojips Katkısının Duvar Karosu Opak Sır Fiziksel Özelliklerine Etkisi

Bu çalışmada, duvar karosu opak sır (DKOS) reçetesine farklı oranlarda katılan fosfojips (FJ) in pişirme öncesi seramik çamurdaki etkileri viskozite, tiksotropi ve yoğunluk testleri incelenmiştir. Daldırma yöntemiyle hazırlanmış sırlı karolar 950, 1050, 1150°C de ayrı ayrı pişirilmiştir. Çarpmaya, ısıl şoka, kimyasallara dayanım ve renk testlerine tabi tutularak fiziksel özellikleri araştırılmıştır. DKOS1 örneği ile opak sırın akıcılığı artmış ve 1150°C pişirim sonrası tüm mekanik testler olumlu sonuçlanmıştır. FJ in sır reçetesine katılmasının geri dönüştürülmesi açısından uygun bir yöntem olduğu görülmüştür.

The Effect of Phosphogypsum Addition on Physical Properties of Wall Tile Opaque Glaze

The effects of addition of phosphogypsum to wall tile opaque glaze receipe are investigated by viscosity, thixpthropy and density tests before sintering. Tiles which are prepared by dipping method are sintered seperately at 950°, 1050° and 1150°C anda re subjected to impact resistence, thermal shock, resistance to chemicals and color tests for searching physical properties of the tiles. The flow behaviour of opaque glaze increased with DKOS1 sample and all mechanical tests gave positive results after firing at 1150°C. The addition of phosphogypsum is considered as an appropriate method for recycling phosphogypsum.
