Overlay mat

Surfacing mats are relatively strong and stiff and are applied when molding flat areas or parts of simple contour. Overlay mats are more drapable and harder to handle but can be used on parts of more complex shape.

A small amount of particleboard is made with a fire-retardant treatment for use in locations where codes require this material, as in some offices and elevators. Particleboards receive overlay and finishing treatments with ease. Wood veneers, melamine overlays, printed paper overlays, vinyl overlays, foils, and direct grain printing can all be done quite simply. A small amount of particleboard is also made in the form of shaped, molded articles such as furniture parts, paper roU plugs, bmsh bases, and even toilet seats. There is another small increment of particleboard made by the extmsion process. These products are made in small captive operations owned by furniture manufacturers which consume all of this production in their furniture. The extmsion process differs from conventional flat-pressed particleboard in that the wood furnish is forced between two stationary heated surfaces. The mats are formed from one edge and this edge is alternately formed and pushed between the heated platens, which are maintained at a distance equal to the thickness of board produced. This is an old, slow, small-scale process, but is stiU in use in at least one location. 

One year later, Burrows published results from a comprehensive series of experiments using 100% Douglas-fir bark as furnish for particleboard (35). No binder was used he relied upon the "self-bonding" properties of Douglas-fir bark. Variables included bark particle size, mat moisture content, pressing pressure, and use of various overlays. Additional boards were made from ponderosa pine, western hemlock, and white fir barks. A pilot-plant-size run was made using results gathered from the study. 

Mycelium overlays the casing and then "mats", becoming flattened and impervious to water. No primordia form. Improper watering and/or too low humidity in the external environment. Evaporation rate too extreme. Scratch and/or re-case. Maintain 95% humidity at pinning. Reduce evaporation rate. If watering, mist lightly and evenly.

An exttemely smooth surface can be obtained on a reinforced plastic molding by placing a thin overlay sheet on the exposed surface of the composite. This type of mat provides little actual reinforcement. It does, however, facilitates a resin-rich surface layer to be incorporated into the molded part. 

After the particles have been prepared, they must be laid into an even and consistent mat to be pressed into a panel. This can be accomplished in a batch mode or by continuous formation. The batch system uses a caul or tray on which a cover frame is placed. Mat formation is induced either by the backwards and forwards movement of the tray or the backwards and forwards movement of the hopper feeder. After formation, the mat is usually pre-pressed prior to hot pressing. Producing a panel this way gives better material utilisation and the smooth face presents a better surface for overlaying or veneering. 

To address these limitations, we developed MatLink, an enhanced matrix-based graph visualization that overlays a linear node-link diagram on the edges and adds dynamic feedback of relationship between nodes (Figure Ic). To assess its effectiveness, we performed an experiment comparing user performance with NL, MAT and MatLink on a set of representative social network analysis tasks. 

A modified SIMCON system, called DUCON [42] was evaluated for overlay and floor applications. In this system the reinforcement consists of mat layers, rather than discrete fibres, allowing a better control of the reinforcement, as well as production of cages with cavities.
