The Particleboard for Fire Retardation from Corn husk coated with Fish Gelatin Thai

Abstract

The objective of the study was the production process and examine the creation of a particleboard for fire Retardation from corn husk coated with fish gelatin. As for the study, first of all, the particleboard was pressed, forming a 50 x 50 x 10 mm³ sheet, and formaldehyde glue was used to be a potential adhesive with the proportion between the adhesive and dry corn husk 30 and 70 respectively, then the cold press was brought with the mold for 30 minutes with pressure force 35.56 kilogram per square centimeter, finally the material was soaked in fish gelatin for 1 hour. The findings showed that a particleboard for fire Retardation from corn husk coated with fish gelatin no burning rate, which passed the UL 94 standard HB. For industrial standard for particleboard with moderate density (TISI 876-2547) it showed that the particleboard for fire Retardation from corn husk coated with fish gelatin included physical properties of density 517.47 kilogram per square meter, moisture content 12.30%, thickness swelling 5.34% and mechanical properties of modulus of rupture (MOR) 6.92 MPa, modulus of elasticity (MOE) 348.43 MPa, tensile strength 0.060 MPa. So three of them did not conform to standard criterion. The findings showed that the surface of a particleboard for fire Retardation from corn husk coated with fish gelatin when looked at magnification power of 30x, 50x, 100x, 200x, and 500x was smooth and rough alternately due to the surface of the particleboard. The result shown a particleboard for fire Retardation from corn husk coated with fish gelatin can resist Fire Retardation and suitable for decoration industry and furniture.
