Abstract

336,754. Halizite Corporation, (Assignees of Hawerlander, A.). March 13, 1929, [Convention date]. Moulds.-Compressed fibrous products are made from materials such as sawdust etc., by first treating the fibrous material with a small amount of a volatile liquid such as petrol and then incorporating the treated material with sufficient phenol formaldehyde resin condensation product to cover the surface thereof, and subsequently subjecting the mass to heat and pressure using moulds with vents to allow the whole of the volatile liquid to escape before the binding agent hardens. Blocks having the appearance of wood are made by coating a sheet of veneer first with petrol and then with binding agent, placing this at the bottom of the mould, filling the mould with prepared sawdust, placing a second sheet of veneer on top and pressing. Example: About 1,000 grams of sawdust are spread upon a table and about 100 ccs of petrol are sprinkled evenly thereover after which the sawdust is treated with 100 ccs of liquid resin binder, and is placed in a steel mould having vents therein. The mould is closed and subjected to a temperature of 400‹ F. at 1,500 lbs. per square inch pressure for about 15 minutes.
