Design of Hot Roll Press to Fabricate TiO2-Coated Fiber for Decomposing Rhodamine B in Water

Article Preview

Abstract:

We have designed new coating equipment for applying nanoparticles of TiO2 on nylon fiber surfaces. A roll hot press with a motor speed of 1740 rpm was able to synthesis ±227 cm/min coated fibers. This equipment is simple and does not require any adhesive materials for attaching Ti02 nanoparticles on the fiber surface. The fiber was passed through a dispersion of TiO2 nanoparticles and then passed through a roll hot press at heating temperature between 600C and 700C. The TiO2-coated fibers were then used for decomposing rhodB-solutions under solar illumination. We observed the TiO2-coated fibers did not affect to properties of TiO2 as catalyst in photocatalysis. The best result was observed when 0,5 gr TiO2-coated fibers were suspended into 250 ml of rhodB-solution in water with a concentration of 1,6 %w/v.
