The article presents new possibilities of revealing fingerprints on non-absorbent surfaces by using Wet Powder White, known and used in Polish dactyloscopy. Powder suspension based on titanium dioxide has been successfully used to reveal fingerprints on the adhesive sides of non-porous tapes, as well as on the inner surfaces of rubber gloves. So far, however, the broader application of Wet Powder White has not been known in Polish dactyloscopic practice. Foreign publications quoted in the article, research conducted and the use of white suspension powder in dactyloscopic opinions dedicated to the visualization of traces unequivocally confirm the high effectiveness of Wet Powder White in revealing fingerprints on non-absorbent surfaces, especially on plastic packaging and areas that have been or could have been previously wetted or subjected to high humidity.

AbstractTwo types of plastic modules for laser diodes and photodiodes are developed and tested under various environmental conditions. The stable operations for both types of modules are confirmed under various long-term aging tests, high humidity high temperature tests (85°C, 85% RH), and temperature cycling tests (-40 / +85°C). These plastic moduless are potentially suitable for economic access networks.

The Ji’an PM No. 3 is the first linerboard machine in China to use multilayer curtain coating technology. Since successful startup at the end of 2011, further development has been carried out to optimize running conditions, coating formulations, and the base paper to provide a product with satisfactory quality and lower cost to manufacture. The key challenges include designing the base board structure for the desired mechanical strength, designing the surface properties for subsequent coating operations, optimizing the high-speed running of the curtain coater to enhance production efficiency, minimizing the amount of titanium dioxide in the coating color, and balancing the coated board properties to make them suitable for both offset and flexographic printing. The pilot and mill scale results show that curtain coating has a major positive impact on brightness, while smoothness is improved mainly by the blade coating and calendering conditions. Optimization of base board properties and the blade + curtain + blade concept has resulted in the successful use of 100% recycled fiber to produce base board. The optical, mechanical, and printability properties of the final coated board meet market requirements for both offset and flexographic printing. Machine runnability is excellent at the current speed of 1000 m/min, and titanium dioxide has been eliminated in the coating formulations without affecting the coating coverage. A significant improvement in the total cost of coated white liner production has been achieved, compared to the conventional concept of using virgin fiber in the top ply. Future development will focus on combining low cost with further quality improvements to make linerboard suitable for a wider range of end-use applications, including frozen-food packaging and folding boxboard.
