Can oily sludge be reused?
Gold mud cannot be reused.
In the casting of small items, sludge is used to squeeze molten metal water. Because molten metal has a certain tension, molten metal cannot enter tiny parts, so it is necessary to give liquid metal water a certain pressure to make it enter those parts.
Sludge is formed by mixing oil and dust. Mainly used in handicrafts, hardware, plastic mold opening, student sculptures, etc., which can be recycled and will not deteriorate for a long time. Sculptures such as handicrafts are highly plastic.
