PVDF a plastic for high-purity water

PVDF is a high-crystalline thermoplastic plastic with outstanding mechanical, physical and chemical characteristics. The FDA conformal high speed plastic belongs to the group of the fluorine polymers, which are inserted for over 20 years in the chemical industry due to the excellent corrosion resistance and/or into Reinstmedienversorgungssystemen of the semiconductor industry due to the high purity. The maximum usual operating temperature is to Rouging with +140 �C, thus is PVDF for a steam sterilization heedlessly einsetzbar.PVDF piping systems without subsequent treatment such as a pickling or passivation is used, cannot material conditionally not occur. PVDF exhibits besides a high chemical stability in relation to passivation means or ozone admission. By the outstanding interior surface quality of the PVDF of pipes, fittings and armatures of RA �m the system crucial advantages offers 0.2 on the micro-biological behavior. The production of the components takes place in the pure area with selected raw material types without softeners or other additives, and ensures thus highest purity of the components. PVDF in the overview highly pure material: freely of softeners, additives and pigment production in the pure area: Pipes, fitting, armature interior surface RA During the entire welding process a flexible Druckk�rper supports the inside of the welding zone for the avoidance of a welding bead. The necessary welding pressure is produced by the thermal expansion of the melted material in axial direction. Will steered during the welding process electronically, examined and documented all necessary welding parameters and cannot by the service personnel be manipulated. The parameters become in detailed minutes by PC printers� and on a label printer printed, in order to ensure the clear traceability of each welding seam. The examination of the WNF� weld takes place by optical control with a source of light from the outside. Due to the Transluszens of PVDF a 100%ige is very simple control of all welding seams also at a later time to accomplish. The confirmation of optical perfect control of the WNF� weld is documented on minutes. Endoskopie or video recordings of the welding seams are not necessary. WNF� welded joints are unstressed, exhibit a homogeneous welding zone with very high mechanical firmness as well as a outstanding surface quality of RA 0.25 �m. Picture: WNF Schweissresultat
