Optimum preparation and thermal conductivity of novel glossy paint prepared from waste of palm oil fly ash composite

Abstract

The optimum preparation and the thermal conductivity of environmental-friendly glossy paint that was prepared from the waste of Palm Oil Fly Ash (POFA) were investigated. For optimum pigment preparations, the aqueous precursor of 45 % wt POFA mixed with 25% wt sulphur, 20% wt calcium and 10% wt fine graphite was sintered at 900 o C to produce a complete crystalline product. The sintered product was milled to become a grayish fine powder pigment. From the SEM images, the grain size was approximately 0.404 µm. The pigments were mixed with a binder, solvent and additives and grinded to become a paint and was then tested (Glossy test, hardness test, adhesion test and thermal conductivity test). From the results, the optimum compositions of a paint are 22% wt POFA pigment, 29% wt alkyd binder, 39% wt polyurethane thinner and 10% wt mix additives (cobalt 10%, lead 32% and N.C Solution). It was also discovered that the paint is a good insulator with thermal conductivity of approximately 78.95 Wm -2 .

The Influence of Injection Molding Parameter on Properties of Thermally Conductive Plastic

“…Figure 3 shows the schematic of the experimental set-up for the conductivity test as refer to Sia C.K. et al [6]. The results were calculated using equation 2 with the assumption that all specimens were subjected to the same atmosphere of measurement.…”

“…Currently, POFA usage is very limited and uncontrollable, and most of it is disposed of towards landfills. Consequently, it has caused numerous environmental harms [13,14]. Earlier, POFA was applied for variety of application and typically used in concrete application.…”
