Environmental Impact Analysis of Automobile Laminated Glass Production

The rapid development of China’s automobile industry has led to increased demand for automobile glass. Combined with the present situation of China’s automobile glass industry, life cycle assessment(LCA) method was adopted for this study, through investigating the energy consumption and emissions during the raw and auxiliary materials acquisition stage and product production stage for auto laminated glass. Then a life cycle inventory was worked out and the data was characterized and normalized by CML analysis method. The results showed that the most serious environmental impacts were Marine Aquatic Ecotoxicity Potential, abiotic depletion potential-fossil and global warming potential, whose proportion of total environmental impact was 92.2%, 2.41%, 1.75%, respectively. Further analysis showed that the influence of float glass was 36%,42% and 33.9% respectively.

Standardization of an external (in air) PIGE methodology using tantalum as a current normalizer in conjunction with INAA for rapid and non-destructive chemical characterization of “as-received” glass fragments towards forensic applications

Rapid automobile glass forensics by non-destructive analysis of “as-received” samples by external (in-air) PIGE for low Z elements with tantalum as a current normalizer and INAA for minor and trace elements using reactor neutrons.

Technology development for automobile glass assembly

The analysis of glass assembly technology and impact of different factors upon strength and accuracy of glass positioning is presented. The modeling of residual stresses after manufacturing as a result of technological impact has shown the presence of residual stresses of stretching along the edges. To the stresses there are summed up assembly stresses caused by shrinkage processes in the glue joint. It is defined that at the minimum width of the glue roll during dry-out a discontinuity of the glue joint along the contour is possible and at the maximum layer width the additional technological stresses in glass arise.
