Effect of process parameter variation on properties of particle board made from Millet cob and rohida wood.

In this study, effects of process parameters, material compositions and adhesive binder content on some physical and mechanical properties of Millet cob and rohida wood particleboards for various categories were investigated as per IS 2380 and compared with medium density particle board as per IS 3087 standards. Particleboards were developed with various process parameters like pressing temperature, time and pressure, also MUF adhesive content variation was investigated for different compositions of millet and rohida wood particle boards. All sample boards had gone through testing for few mechanical properties (internal bond, MOE, screw holding capacity and MOR) and physical properties (density, surface Roughness SR, water absorption WA and thickness swelling TS). Obtained results have shown that increase in composition of rohida wood particles improves the properties of particle boards. After optimization of process parameters and adhesive content, most of the samples either made of rohida particles or with composition of rohida and millet particles had been passed through various tests as per IS 2380 and found fit for the medium and high-density particle boards category, when compared to IS 3087 Standards. While the boards made of millet cobs only can be utilised as low-density particle boards. [ABSTRACT FROM AUTHOR]
