The physical and mechanical properties are key indexes for determining the quality of particleboards. For this reason, a study on evaluating particleboard via new method has considerable value. Thus, based principal component regression (PCR) analysis random forest (RF) is proposed in paper. First, problems requiring resolution described after analyzing production process parameters as well par...
The objective of this paper was to examine the effect that chemical modification of raw material had on fire resistance of two panel products, namely Oriented Strand Board (OSB) and particleboard and to investigate the influence of the anhydride type. The results have shown that chemical modification affected the ignition and glowing time of two wood panel products.
Pleurotus ostreatus (PO) is one of the edible mushrooms cultivated in baglog as medium. Baglog’s productive age around 4-5 weeks. The more PO produced, amount waste also increases. main component wood sawdust, which contains lignocellulose; therefore, has great potential to be used a raw material for making particleboard. This research aims make particleboard from and determine effect type adhe...
Low mole ratio urea-melamine-formaldehyde (UMF) resins synthesized with 2.5% and 5.0% melamine levels added at the beginning, middle, and end points of the first alkaline step of the typical urea-formaldehyde (UF) resin synthesis procedure were compared with typical UMF resins synthesized with melamine additions made at the final alkaline step. Various resin analysis, particleboard preparation,...
particle size, board density and adhesive content are the most important factors, influencing on physical and mechanical properties of particleboard. in this study the effects of density, adhesive content and particle size on withdrawal strength of particleboard made from populus (populus alba) particles have been studied. three levels of density including 0.65, 0.7, and 0.75 g/cm3, three level...
For the development of a cost-effective melamine-modified urea formaldehyde resin (MUF), the study evaluated the effects of reaction pH and melamine content on resin properties and bond performance of the MUF resin adhesive systems. Eight resins, each with three replicates, were prepared in a factorial experiment that included two formulation variables: two reaction pHs (i.e., 4.5 and 8.0) and ...
Particle board is mostly used as alternative to wood at present age reduce the pressure on solid wood. Different raw materials, woody and non materials are particle various resins binder. Now-a-days, vegetable wastages also utilized. This study was conducted compare feasibility of using Brown Mustard (Brassica juncea (L.) Czern) plant wastage for manufacturing particleboard. The physical mechan...
The development of natural adhesives derived from non-fossil resources is very important for the future. In this study, by taking sugarcane bagasse as the raw material, without using any synthetic resin but adding some eco-friendly additives (citric acid and sucrose), low density particleboards were successfully developed. The effects of board density and additive contents on the physical and m...
