The production of phenolic resin-based abrasive with use of solid waste sand of foundry industry

Öz

Molding sand, which becomes solid waste after casting processes, is an important item to be recycled and used, as well as turning it into useful products with economic value, due to the fact that it creates an environmental problem and increases storage costs. The studies on this subject are still insufficient. In this study, the SiC phase were obtained from solid waste casting sand whose basic material is silica and from phenolic resin as a C source, and their usability as an abrasive was investigated. Densities of the products were measured with a Helium pycnometer; the hardness with a Shore D device; pore structure and distribution with the BET method; the surface functions with a FTIR Fourier Transform Infrared Spectrometer; the development of bonds in the structure and morphology with a Confocal Raman Microscope; the phase analysis using the XRD method; and microstructural examinations with SEM analysis. As a result, it was determined that a high temperature was needed to obtain the SiC phase with the conventional pressure less sintering method using solid waste casting sand, but the resin used did not withstand the required high temperature.

Döküm endüstrisi katı atık kumu kullanımı ile fenolik reçine bazlı aşındırıcı üretimi

Öz

Döküm işlemlerinden sonra katı atık haline gelen kalıp kumu, çevresel bir sorun yaratması ve depolama maliyetlerini artırması nedeniyle geri dönüştürülerek kullanılması ve ekonomik değeri olan faydalı ürünlere dönüştürülmesi önemli bir maddedir. Bu konuda yapılan çalışmalar henüz yetersizdir. Bu çalışmada, temel malzemesi silika olan katı atık döküm kumu ve C kaynağı olarak fenolik reçineden SiC fazı elde edilmiş ve aşındırıcı olarak kullanılabilirlikleri araştırılmıştır. Üretilen ürünlerin yoğunlukları Helyum piknometresi ile sertlik değeri Shore D cihazı ile gözenek yapısı ve dağılımı BET yöntemi ile; yüzey fonksiyonları FTIR Fourier Dönüşümlü Kızılötesi Spektrometresi ile; yapı ve morfolojideki bağların gelişimi Konfokal Raman Mikroskobu ile; faz analizi XRD yöntemi ile; mikroyapısal incelemeler SEM analizi ile yapılmıştır. Sonuç olarak, katı atık döküm kumu kullanılarak yapılan konvansiyonel basınçsız sinterleme yöntemi ile SiC fazının elde edilmesi için yüksek sıcaklığa ihtiyaç duyulduğu, ancak kullanılan reçinenin gerekli yüksek sıcaklığa dayanamadığı belirlenmiştir.
