  • Air drying alkyd resins from seed oil of kara wi la MC43 
    Prashantha, MAB; Prernachandra, JK; Amarasinghe, ADUS [Conference-Extended-Abstract]
    Alkyd resins are a special family of polyesters which are mainly limited in application of surface coatings. The popularity of alkyd resins in surface coating industry throughout the world is due to cost effectiveness ...
  • Design of an effective heat exchanger for cinnamon oil extraction 
    Silva, MD; Amarasinghe, ADUS [Conference-Extended-Abstract]
    Lack of knowledge in heat exchanger design and fabrication is the major hindrance for improving the cinnamon oil extraction process in Sri Lanka. Most of the extraction plants use submerged coils in still water where the ...
  • Improvement of film properties of alkyd resins manufactured from seed oil of karawi la MC43 
    Prashantha, MAB; Premachandra, BAJK; Amarasinghe, ADUS [Conference-Extended-Abstract]
    Versatility of alkyd resins is due to its application in many different areas such as decorative paints, stoving paints (industrial paints), water dispersible alkyd paints and printing inks. Alkyd resins are also used to ...
  • Mathematical modeling of deodorization process for a cross current multistage deodorizer 
    Ariyapperuma, YP; Amarasinghe, ADUS [Conference-Extended-Abstract]
    Deodorization of fats and oils is necessary to remove the undesirable flavor and odor components that are naturally present or created during processing. A mathematical formula was derived to establish the relationship ...
  • A new mathematical model to predict the iodine value of fatty oils 
    Prashantha, MAB; Premachandra, BAJK; Amarasinghe, ADUS [Conference-Extended-Abstract]
    Iodine value is defined as the number of centigrams of iodine per gram of oil sample. Drying property of fatty oils mainly depends on the type of unsaturated fatty acids and relative amounts of each type of fatty acid in ...
  • Seed oil of kara wila mc43 as a source of drying oil 
    Prashantha, MAB; Premachandra, JK; Amarasinghe, ADUS [Conference-Extended-Abstract]
    Considerable amount of conjugated trienoic (eleosteric acid) or methylene interrupted trienoic (lenolenic acid) acids in fatty oil contribute to form a dried film when thin film of such fatty oil is exposed to air. Generally ...
