Identification and monitoring of the polymer thermo-shrinkable couplings and coatings by the relief marking

The advanced identification and monitoring method of both shrink couplings and coatings operating, typically used as building services or utility lines, based on relief (tactile) marking is offered. The determination method of temperature operating marking mode for different shrink polymer types using adapted hot stamping press equipped both isothermal processing and thermo-cycling laboratory tools is proved. Applicability of the developed time-temperature superposition principle for polymer marking mode definition is shown as exemplified by both PET and PVC shrink films processing. The optimal time-temperature mode calculation procedures at the local polymer processing according to both shrinkage force maximum speed dropping criteria and fixed difference of polymer contractile force as a result as isothermal stamping processing are shown.The advanced identification and monitoring method of both shrink couplings and coatings operating, typically used as building services or utility lines, based on relief (tactile) marking is offered.
