Fumes generated during laser processing of polyvinyl chloride
An approach to the assessment of fumes produced in laser material processing is presented. The subsequent design of the fume containment system and sampling strategy is detailed. Polyvinyl chloride (PVC) has been selected for investigation and the complexity resulting from the plethora of additives is discussed. Qualitative results from the preliminary studies of CO2 laser cutting of PVC are pr...
متن کاملEffect of processing temperature on the properties of a polyvinyl chloride maxillofacial elastomer.
Mechanical properties and color of a plasticized polyvinyl chloride (PVC) maxillofacial elastomer were evaluated at processing temperatures from 140 to 190 degrees C. The properties were dependent on processing temperature. Specimens prepared at 170 degrees C had optimum mechanical properties with minimal discoloration.
متن کاملThermal Degradation of Polyvinyl Chloride
A survey is given of the recent advances in the study of and the present knowledge of the thermal degradation of polyvinyl chloride. The sites for initiation of the thermal degradation, the mechanism of the dehydrochiorination, the discolouration of PVC by heat and the influence of plasticizers on the rate of degradation are discussed.

قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...
