Characteristic of Chitosan Adhesive from Shell Shrimp Litopenaeus vannamei and Their Application for Producing Particleboard

Abstract

Abstract The shrimp shell that rich compounds of chitin can be converted to produce polysaccharides called chitosan. The chitosan can be utilized as bioadhesive for substitute chemical based adhesive for producing particleboard. The purpose of this study was to evaluate the effect of different concentration acetic acid (CH 3 COOH) as the solvent to made chitosan adhesive and physical and mechanical properties of the produced particleboard by using sawdust waste. Chitosan adhesive formulation will be used as an adhesive by dissolving chitosan powder with CH 3 COOH solvent. This research focused on optimization the solvent content wich is CH 3 COOH in different concentration such as 0.5%, 2% and 4%. Particleboard with size of 25 cm x 25 cm x 0.7 cm with 8%, target density 0.75 g/cm 3 were produced using sawdust waste of Paraserianthes falcataria. The processing condition were 180°C in temperature during 12 minutes with pressure of 25 kg/cm 2 . The research showed, there is no particular trend in particle board characteristics related to solvent concentration. Physical and mechanical Properties fulfill requirement of JIS A 5908-2003 for Moisture Content, MOE and IB. The produced particleboard that using chitosan as bioadhesive and sawdust waste as particle is potentially to be developed technically based on the quality of the particleboards produced.
