Abstract According to the anticorrosion demand of petrochemical pressure vessel storing acid medium, phenolic epoxy resin and modified amine curing agent was used, a tertiary accelerator added, fast-curing acid-resistant anticorrosive coating with excellent acid-resistance developed by adding appropriate amount flake pigments fillers such as graphene chemical additives. Through Performance Test...

UNLABELLED The purpose of the study was to compare temperature rise during polymerisation of resin based composites (RBCs) with two LED light curing units (LCUs) compared to a halogen control light. METHODS Forty-five extracted molars, patients aging 11-18 years were used. Thermocouples (TCs) were placed in contact with the roof of the pulp chamber using a 'split-tooth' method. Teeth were pla...

To reduce the labor cost and the workload required in the tobacco curing process, an intelligent tobacco curing control technique adopting color identification of the tobacco leaves is proposed. The HSI color space is used in color segmentation and the color recognition with fuzzy decision is used in the curing process. The curing controller can identify the curing stage by the color features o...
