| Popis: | Hollow ceramic product is fabricated generally using slip casting technique. The conventional processes produce slip and mould waste which require for disposal schedule. A rotary moulding technique is a feasible process for producing hollow shape ceramic product and eliminates the waste. This paper focuses formulation of the slip and process parameters of the rotary moulding for hollow ceramic product fabrication. The formulated ceramic slip is poured inside the mould rotated at 2-axis system inside a controlled chamber with specific temperature, speed and time for producing green body hollow ceramic product. This process uses minimum amount of ceramic slip and long lasting mould material which will reduce ceramic waste to environment and simplify the manufacturing process for mass production. Using small amount of polymer based dispersant and coagulant agents, experimental analysis resulted the green hollow porcelain product which was successfully removed during de-moulding process without any breaks. The hollow product produces homogeneous forms of ceramic structure after firing procedure and 1.9 MPa green strength with addition of small amount of binder. |
