Development of Industrial Automotive Paint with Natural Raw Material Castor Oil as a Substitute of Polymeric Plasticizer

Polymeric materials from natural resources have engrossed a set of developmental interests in recent years. The development of low priced automotive paints by the use of caster seed oil which has been introduced as a substitute of polymeric plasticizer materials focusing at this time to the polymer and paint industries due to the massive world wide availability, embedded biodegradability, low cost, and outstanding environmental characteristics (i.e., low toxicity toward human beings). The advantages of these outstanding natural characteristics are now being taken in the fields of research and development. Oil derived polymeric materials and composites are being utilized in many applications including paints, surface coatings, adhesives and nanocomposites. The endeavor of this research paper is likely to provide a basic enlightenment on the castor seed oil applications in polymeric activities with reference to their recent developments. Particular emphasis has been placed on the study and applications of drying oils in almost all low priced decorative and protective surface coatings. For the purpose of extraction of the oil, simple distillation method was used. Paint formulations i.e., the theoretical formulation, milling with calculated constituents to get mill-base, grinding and dispersion of pigment particles, stabilization, let-down and make-up processes were carried out within the laboratory conditions. Different paints were formulated by incorporating the base pigment rutile TiO2, alkyd resin alongwith other constituents as determined. The compatibility, viscosity, opacity, gloss, adhesion, flexibility and other quality control tests of castor seed oil plasticized automotive paints were carried out as per ASTM/BIS test methods and compared with the testingrsquos standard of the Berger Paints Limited. The results were found as specific gravity: 0.95plusmn 0.02), refractive index @ 280C: (1.79plusmn 0.01), viscosity @ 28nbspoC: (0.425 plusmn 0.12), pH: (5.800 plusmn 0.00), flash point: (256.000plusmn 1.20oC), adhesion: 100%, gloss: 95-99%, 650 hours passed in salt spray test and 600 hours passed in weathering resistance test all parameters were within the range of automotive paint applications and quality specifications. Castor-seed-oil has been appraised as an effective plasticizer and film-former in automotive paint formulations. The humidity content of the caster seeds was low, therefore, has been introduced as a material of good quality for the further use in other glossy automotive paint formulations.

High efficiency multi-junction solar cell design

Energy from the sun is the best option for electricity generation as it is abundantly available everywhere and sustainable source. Advance of Photovoltaic (PV) technology in recent years has made solar energy one of the practical alternative energy sources available in the energy market. In order to make the PV energy more affordable and cost effective, major focus of the research community and industry is improvement on power efficiency of PV systems. Early stage of solar panel manufacturing known as process technology plays a crucial role in achieving above limits. This paper presents a novel process technology for solar panel with 6 junctions.

Prediction of seam performance of light weight woven fabrics

Light weight fabrics are selected for their aesthetic qualities, drape, and handle. But these fabrics are difficult to sew. Seams are the basic elements in a structure of any apparel. Seam performance affects the quality of the apparel product. In this research seam performance of two kinds of light woven fabrics differs in their construction (chiffon and satin) were studied in terms of seam strength, efficiency, and seam strain. The effect of some sewing parameters (sewing thread count, stitch density, needle size, stitch type) on seam strength, efficiency, and seam strain were investigated. Regression equations which can predict each of the previous parameters were concluded in both warp and weft directions. It was found that the stitch density and the interaction between thread count and stitch type affect warp seam strength for both chiffon and satin fabric. Sewing thread count has significant effect on seam stress in both directions for both fabrics under study. Also it affects seam strain in warp direction for satin fabric. The significant effect of sewing needle count on seam performance appears only in seam stress in warp direction for chiffon fabric.
