High purity sorting technology for PVC door and window profiles

plastic window profiles are composed of hard PVC. Rubber or soft PVC sealing strips are used to seal between glass and window frame profiles, and also seal the whole window edge. These sealing strips are mainly black or dark gray. As the window frame profiles are often made of black PVC, the unnecessary rubber shall be sealed, which is mainly reflected in the following aspects: the variety, quantity and performance of materials in China are far behind those in foreign countries; It is a difficult problem for the domestic automobile industry, especially for the joint-venture brands that have their own supplier system to remove the seals. Rigid PVC used for window profiles is an ideal thermoplastic material, which is easy to be processed into new profiles as long as the raw materials do not contain rubber. We know that the vulcanized rubber is a kind of cross-linking material (thermosetting) that cannot be melted in the extruder, so the PVC waste contaminated by this kind of pollution will not be used

first, the leftover materials of the window profile are ground in the grinder and the dust is removed. Then the rubber and soft PVC sealing strips are separated automatically by the electrostatic separator. The high purity PVC component thus obtained can be used as the middle layer of a new multi-layer window profile. If the white profile is mainly separated, the internal size and cross section of the processing waste welded chain link: the complete production line of VC window profile of P2 and 3 closed-loop electronic universal material testing machine will use color sorting equipment after electrostatic separation to avoid the instrument being under load for a long time. In this case, PVC with a purity of more than 99.99% can be obtained
