Embodiment 1
[0026] Collect the bone china production waste sludge and sewage into a special sedimentation tank; press filter the bone china production waste sludge to make the moisture content below 25%, and store it in the sun for later use; the waste water can be used for landscaping and toilets rinse.
[0027] Mix the prepared bone china waste sludge and other raw materials according to weight percentage: bone china production waste sludge 76%, Fe 2 o 3 12%, plastic clay 5%, cellulose 5%, sodium polyacrylate 2%, put into ball mill, then add water with the same weight as dry material, ball mill for 8 hours, ball mill fineness ≥ 80%, then sieve, press filter , to obtain a filter cake; the filter cake is refined into a mud bar with a vacuum mud refining machine, pressed into a semi-finished product with a rolling press, and fired at a temperature of 1100±50°C to obtain a natural texture, fine hand feeling, and water permeability Red pottery is a high-end product for high-end gardens.
