Enhance the properties of the stainless steel Solar basin by using new ceramic coatings

Abstract

Solar energy is increasingly being used as a renewable energy source in water analysis, energy devices, treatment systems, data logging, and analytical instruments, providing sustainable and cost-effective solutions. A 316 stainless steel sink was utilized with the aim of enhancing its thermal insulation properties. Ceramic materials such as mullite(3Al2o3.2sio2), titanium dioxide(Tio2) , and magnesium oxide(mgo ) are identified as effective insulating agents for improving the insulation processes of a stainless steel 316 basin.Mullite powder is added in weight ratios of 0.7%, 2.21%, 3.79%, and 3.78%. Titanium dioxide is also added in weight ratios of 0.3%, 0.79%, 1.39%, and 0.7%. To enhance the insulation ratio, add 0.6% magnesium oxide to S5. .The coating process involves air-brush painting on the stainless steel sheet to ensure a uniform and durable application. Various tests, including X-ray diffraction(XRD), scanning electron microscopy(SEM),Atomic force microscope (AFM), thermal conductivity measurement, adhesion strength testing, density measurement, coating thickness analysis, evaluation of UV radiation resistance, and porosity determination, are conducted to evaluate the performance and characteristics of the coatings. Thermal insulation was achieved for sample S4, resulting in a thermal conductivity value of 0.231411 W/m•°C, along with an associated increase in pore percentage of 0.88%. Additionally, sample S4 exhibited a lower density value of 1.22 kg/m³, attributed to the incorporation of oxide. In comparison, sample S5, composed of magnesium, exhibited the highest thickness among the remaining samples, measuring (540μm). The project's objective is to create a sustainable and enhanced method for water desalination by leveraging renewable energy sources and advanced insulation techniques incorporating ceramic coatings. This innovative approach aims to decrease energy consumption and minimize environmental repercussions, thereby facilitating the provision of safe drinking water, particularly in regions grappling with water scarcity. Additionally, the project seeks to enhance the properties of a stainless steel 316 basin by reducing thermal conductivity, ultimately increasing the insulation percentage. This endeavor involves harnessing solar energy as a means of achieving these goals.
