Abstract

OCR 09WP 24 / 01 / 2568 This invention relates to a method for preparing composite fibers of titanium dioxide and zinc. Tungstate (TiO2-ZnWO4) on fiberglass sheets using the electrospinning method of the solution. The composite material is applied to the fiberglass sheet before firing, ensuring strong adhesion of the fiber layers to the fiberglass sheet. Due to their strength, the resulting composite sheets can be used as filters for accelerated wastewater treatment. The next photoreaction.

OCR 09WP 24 / 01 / 2568 1. Method for preparing titanium dioxide and zinc tungstate composite fibers on fiberglass sheets. Which consists of the following steps: a) Provide a composite solution consisting of: - Polyvinylpyrrolidone in the range of 3 to 8 percent by weight, - Alcohols containing 1 to 4 carbon atoms, in the range of 45 to 55 percent by weight. - Metatungstate salts in the range of 0.5 to 2 percent by weight, - Dimethylformamide in the range of 15 to 25 percent by weight, -Compounds that are sources of zinc, in the range of 0.5 to 2 percent by weight. -Compounds that are sources of titanium, in the range of 5 to 15 percent by weight, and - Acetic acid in the range of 5 to 15 percent by weight. b) Take the composite solution from step a) and form it into a fiber layer on a fiberglass sheet. Its unique characteristic is the formation of fibrous layers carried out using the electrospinning method. (Electrospinning) of the composite solution onto a fiberglass sheet, then it is fired at a temperature... In the range of 300 to 900 degrees Celsius. The electrospinning method described above works by specifying the distance of... The electrodes are in the range of 10 to 25 centimeters, the potential difference is in the range of 25 to 50 kilovolts, and the rate... The rotation speed is between 5 and 15 revolutions per minute.
