METHOD AND INSTALLATION FOR THE PRODUCTION OF PLASTIC PRODUCTS WITH THE AID OF A HOT MIXTURE OF PVC POWDER AND ADDITIVES, AND A HOT MIXER SUITABLE FOR USE WITH THIS METHOD

摘要

Disclosing one kind, with extruder (1), with extruder hopper (2), it is provided the PVC powder and additive hot mixing area that a hot-laid mixture is discontinuously obtained by mixing for producing extrusion plastic products, utilize supply frictional heat, the wherein frictional heat of the PVC powder of the first amount and excessive additive and supply, then by the PVC powder of the mixture homogenization so obtained same mixed zone and magnitude of recruitment, in this way, final mixture has the additive of required concentration, is directly fed to extruder hopper (2) after the homogenizing that hereafter mixture of the heat obtains. A kind of equipment is for producing plastic products by squeezing out, including discontinously operation hot mixers are also disclosed and the hot mixer (3).
