Fumes generated during laser processing of polyvinyl chloride
نویسنده
چکیده
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 presented together with an appraisal of the problems involved in extending this to quantitative analysis. Benzene, hydrogen chloride (HCI) and methyl methacrylate were found to be the dominant emissions.

Introducing a novel Polyvinyl chloride/Tungsten composites for shielding against gamma and X-ray radiations
Introduction: This study introduces a novel polyvinyl chloride (PVC)/tungsten composites with characterization of their shielding properties by employing different techniques. Methods: The PVC/tungsten composites were produced by employing various weight fractions of tungsten micro-particles including 0, 20, and 40 % wt via melt blending method. In the next st...
متن کاملRespiratory illness caused by overheating of polyvinyl chloride.
On 9 August 1979, 62 (30.8%) of 201 workers and one of 60 management personnel in a polyvinyl chloride (PVC) fabricating plant developed acute upper and lower respiratory irritation, headache, nausea, and fainting. All were taken to hospital; none died. Sixty of the patients were women. Interviews two weeks later with 57 affected and 14 unaffected workers disclosed that illness had followed exp...
متن کاملThe Role of Exposure to Phthalates from Polyvinyl Chloride Products in the Development of Asthma and Allergies: A Systematic Review and Meta-analysis
BACKGROUND Phthalates from polyvinyl chloride (PVC) plastics may have adverse effects on airways and immunologic systems, but the evidence has not been reviewed systematically. OBJECTIVE We reviewed the evidence for the role of exposure to phthalates from PVC products in the development of asthma and allergies. METHODS We conducted a Medline database search (1950 through May 2007) for relev...
متن کاملDust emission rates from food processing.
A field study was performed to develop emission rates for dust exposure at a food processing facility. Eight 2-hour periods were monitored over 2 days. Area total suspended particulate samples were collected on 37 mm polyvinyl chloride filters with 5 mum pore size according to NIOSH Method 0500. Filters were analyzed gravimetrically. Ventilation and production activity data were collected durin...
متن کاملTensile properties and fatigue behavior of AHSS-DP 350/600 subjected to laser shock processing
This work presents the effects of strain rate on the tensile properties and fracture morphologies of AHSS-DP 350/600 subjected to LSP. Fatigue crack growth test was performed to evaluate fatigue behavior in the metallic plate of AHSS-DP350/600. However, this material is used in automobile industry and enhancing it fatigue resistance is a challenge in material engineering. In order to evaluate a...
