Acrylic binders for dry pressing ceramics.

Wax emulsions behave like inter particle lubricants when bodies are wet and like binders when dry. The performance of binders such as polyvinyl alcohol pva polyethylene glycol peg and polyacrylic commonly used in forming ceramics by dry pressing methods was evaluated on spray dried. Binders are substances that improve the mechanical strength of green ceramic bodies so they can pass through production steps before firing without breakage. Wall floor tile is made of high quality earthenware clay as main raw materials which is firstly added in other materials to make raw meal and then after semi dry pressing molding fired at a temperature around 1100 c it is classified to glazed and unglazed types.
