PET plastic molding processing can injection molding, extrusion, blow molding, coating, adhesive, machining, plating, vacuum metallized, printing, etc
PET in molten state of the rheological property is good, the influence of pressure on viscosity than temperature, therefore, mainly from the pressure to change the melt flow. 1, plastic processing because of PET macromolecular contains aliphatic, have certain hydrophilicity, aggregate at high temperature is more sensitive to water, when the water content more than limit, in the process of PET molecular weight drops, products with color, crisp. Trapped this, in the processing of materials are required before drying, the drying temperature of 150 ℃, 4 hours, generally for 170 ℃, 3-4 hours. Available empty reflection test material is completely dry. Recycling material proportion generally not more than 25%, and the recovery material completely dry.
