4. Procedure for extracting chessboard from recycled materials generated by four packaging paper wastes

摘要

The program uses polyurethane as a polymeric material and requires mechanical equipment to make a homologous mixture through a tombola and a news media, especially because it has an optimal process control temperature system, as well as normal news and mold systems. The recovered material is ground in the form of flakes by a shredder, which does not tear it when shredding, and the measurement range is from 5mm to 25mm.It is finished by sieving or sieving in the mill. The specific quantity is 20-25kg per plate as the weight reference, which is used for the use of the formula, depending on the size, thickness or density of the processed plate.
