Investigation of starch additives in MDF manufacturing posibilities

In recent years wood based panels have found widely use area and because of this demand increased day by day. But placea of use moisture condition, liquid and vapor sensitivity effects using areas. Due to the fact that R&D researchs trying to enlight fiberboard composite materials production proces and add different additive improve some technological properties, find new way to development for market requirments. In this case changing of fiberboards properties with using Starch and examine boards exchanging water, increasing thickness, surface vertical tensile strenght and formaldehyde emission amount detection. In this study use as a additive Starch as known as commercial name Glucidex, adding ratio of UF glue sequentially 0%, 3%, 5%, 8%, 11% and 15% produced Medium Density Fiberboard's (MDF) different tecnological properties, dimentional stability and formaldehyde emission properties analysed and compare to control specimens. Achieving datas, using Glucidex produced boards dimentional stabilities are not changed. Increasing Starch use decrease mechanical properties and formaldehyde emission.
