Lignocellulosic fibers have received much more attention than ever before from the research community all over the world during the past few years because of their enormous advantages. A study on the preparation of new series of polymer composites using Pine Needles as a reinforcing material in Urea Formaldehyde resin has been made. Mechanical properties of intimately mixed particle reinforced ...

Bamboo is suitable to be a material for the production of new products that can used indoors and outdoors. Five-, seven- nine-ply laminated woven bamboo mat boards from semantan bamboo, Gigantochloa scortechinii, were fabricated in this study. G. scortechinii has been commercially structural application easily available Malaysia. The present work investigated physico-mechanical properties flamm...

Woodceramics were fabricated in a vacuum through carbonization of wood powder impregnated with phenol formaldehyde (PF) resin. The effects of carbonization temperature and mass ratio of wood/resin on electromagnetic interference (EMI) shielding effectiveness (SE) and morphology of woodceramics were explored. The PF resin made wood cell walls have the characteristics of glassy carbon. Wood axial...

Abstract This article proposes the preparation and microwave thermal cured (MTC) epoxy-modified phenolic fibers for first time. Epoxy-modified thermoplastic resin was prepared in acidic condition using phenol, formaldehyde, epichlorohydrin as reactants, then underwent additive reaction with formaldehyde to obtain thermosetting resin, which converted into nascent through wet spinning. Finally, w...

COMPARATIVE PHENOLIC CONTENT AND ANTIOXIDANT ACTIVITIES OFBLUEBERRY (VACCINIUM CORYMBOSUM) AFECTED BY IN VITRO DIGESTION

This paper reports on formaldehyde exposure and its health hazards in a melamine manufacturing industry. The mean of workers' exposure was measured according to 3500 NJOSH and was found to be 1.44±O.2l, and 2. 17±O.24 ppm in morning and evening shifts, respectively. For stationary ones it was 1.37±O.20, and 2.06±O.25ppm, respectively. The results show that formaldehyde concentration at the...
