BRIEF DESCRIPTION OF THE PRESENT INVENTION pND IMPLICATION
Powder blasting nozzle Figure 1. (Further P.B.N.) is used in the application of powdered adhesive into a rotating drum. The neccessary blasting force to blast powder is created by two or single source of compresed air. Primary air is supplied by main blower, which is currently used to deliver powder into one exit orifice usually at the infeed of the rotating blender.
The secondary source of compressed air is what makes this invention special equaly distributes the total quantity of powder through several orifices from the main delivery pipe, via P.B.N. (Figure 2).
Figure 3 is a cross section view of the powder blowing nozzle.

These simple systems do not influence the distribution of the powder on the strands that are coated with wax emulsion.
The conventional way of distributing the powder resin is to dump it into the blender and let the tumbling of the equipment do the work. The probability of even distribution of the powder resin is totaly dependant on the residential time the strands in the blender.
(dwell time), the RPM of blender, the humidity of the strands, angle of the blender, the wax dosage, the power dosage, etc..
It has been determinated that the distribution on the powder resin on the strands in industrial blenders can be improved by «blasting» or in other words blowing the powdered adhesive against the flow of strands, in the blender.
The jets of air-powder resin come in contact with the airborn strands forcing them to twist more frequently, while they are « air bom » during dwell time in the blender.
The end result is that strands or wafers exiting the blender have uniform and superior distribution of anchored powder on both sides of strands or wafers.
Ultimatly the wafers or strands have a more «EFFECTIVE COVERAGE» of anchored powder in the droplets of liquid catalyst or wax emulsion and this way coated strands or wafers give the manufacturer a superior product. It has to be stressed that choice of dirrecting the jets of powder and liquid anchoring droplets (catalyst of wax emulsion) allows user of such blending, to achive permanent residency of droplet-powder grain combination on surface of strands or wafers. Since it is essential for panel of OSB or waferboard to have high strength and mainly uniformity of properties, through the whole area of panels, such described coverage of strands or wafers will insure that.
In the case when hardwood species are used to make strands or wafers, powdered resin has a tendency to fall off the strands, due to the smoothness of the surface of hardwood strands or wafers. To compensate this fact, wax emulsion or liquid catalyst (for catalysing the powder), can be used in situe with powdered resin, to anchor the powder to the surface of the hardwood strands or wafers.
EXAMPLE
Hardwood species (sweat gum) and southern yellow pine, birch, were used to prepare strands in pilot plant flaker. Such mixture of strands were blended three different ways.
FIRST WAY : 1% wax emulsion was sprayed of strands, than 2.3% Phenolic powder was added is one dosage strands were than tumbles in rotating blender for 4 minutes and than stored for a mat forming.
SECOND WAY : 1% wax emulsion was sprayed on identical mixture of strands, follow by 2.3% Phenolic powder blowen via P.B.N. for time of 45 seconds.
Then blender was stopped and coated strands were stored for a mat forming.
THIRD WAY : 1 % wax emulsion was sprayed on identical mixture of strands, 1 liquid catalyst (on mass of wood) was sprayed through J.M. Brooks liquid nozzles simultaneusly with 1.3% Phenolic powder blowen through P.B.N. Also in this case liquid catalyst and Phenolic powder were spray-blowen within 45 seconds (dwell time), coated strands were stored for mat forming.
24X24 three layers panels were pressed for 2 minutes 40 seconds (day light to day light) at 190°C.
Adhesives (surface and core powders as well as liquid catalyst were used in this experiment).
Random oriented mat was hand formed and panels were pressed.
Target density was 42 lb/ft3.
PANELS per each way were presse to insure validity of results.
