Surface structure embossed

Type B1 Type Cl Packing made of 0.2 mm embossed metal sheet with special surface structure and round form flow channels Similar to type Bl, but made from IT FE or polypropylene Rectification under overpressure, normal pressure and vacuum Absorption 100-500 0.6-3.0 Bl-300 to 30 Bl-300 ca. 4 Bl-300 0.1-2.0 Bl-300... 

Mechanical softening treatments may involve fibre displacement, web buckling, and affect the absorbency of the resulting structure. Embossing, calendering surface glazing and other mechanical treatments can be utilized to modify web properties and the related absorbency characteristics. 

In contrast, the polyurethane dispersions used in the pigment coat are of medium hardness. A portion of the polyurethane dispersions may also be replaced by polyacrylate dispersions. These must not have an adverse effect on the cold flexing endurance and so the polyacrylate dispersions used must have a low glass transition temperature. The high rub-fastnesses are primarily achieved by the crosslinking of the top coat Useful crossHnkers include, for example, modified aliphatic polyisocyanates. The leathers are strongly embossed to conform the surface structure of the leathers to the interior styling of the car.

Malax high-performance structured packing (Fig. 8.11 ). Relatively flat crimps, somewhat rounded crimp apexes, and deeply embossed surfaces with tiny perforations distinguish lntalox high-performance structured packing. It is available in three sizes in metals from the Norton Company. 

Extrusion is the most commonly adopted shaping process used in the structural ceramic industry. The majority of products receive their final shape directly by means of the extrusion process. This does also apply to extruded roofing tiles, but these may, however, be subjected to ftirther forming, that is re-pressed, for example in the manufacture cambered tiles and to obtain an embossed surface. Slabs are extruded for the production of pressed roofing tiles, the final shape of which is achieved by a repressing process.
