Premium Wheat Flour for Plywood Glue Mixes used for inside veneer core and face veneer lamination .

Wheat flours USED FOR the inside veneer core lay-up and wood face veneer lamination are much different ,but most of the factories they are using the same Wheat flours .If for commercial plywood ,just use a little lower quality Wheat flours for inside core ,a little higher quality of Wheat flours for face veneer lamination .This kind of Wheat flours we called them industrial grade Wheat flours can not be eaten .

how much percentage of the glue wheat flour with the mixed glue ?HOw is the viscosity and other requirements ?

Wheat flours are the only principal starch-based extenders that are employed today in urea-formaldehyde plywood glues. These products are unique in that they can provide viscosity in certain adhesive systems without the starch portion of the flour becoming gelatinized. This property is usually associated with the gluten protein portion of wheat flours. Wheat gluten has considerably different properties compared to the protein portions of other cereals, such as corn, rice, sorghum, etc. The gluten protein of wheat is responsible for the dough forming properties which make wheat flours particularly useful in the production of bread, cakes, pasta and related bakery products.

Plywood has been defined as a crossbonded assembly made of layers of veneer (a thin layer or sheet of wood) in combination with a core of lumber or of plies joined with an adhesive. The grain of alternate layers of veneer is crossed, generally at right angles, which provides a panel with improved strength and dimensional stability compared to the original wood.

To describe a veneer plywood completely it is necessary to indicate three criteria including the species or group of timber, the grade of veneer, usually confined to the face and back veneers, and the bond or type of adhesive used. These factors generally limit the application in which the plywood can be employed.Viscosity and bond quality of urea formaldehyde adhesive extended with acid modified It was the goal of this research to determine if sago starch could be used to replace wheat flour as an adhesive extender of Urea-formaldehyde plywood adhesives through either chemical modification of the starch or modification of the adhesive formulation strategy
