Hot air is one of the simplest ways to get materials sealed together. Not nearly as intrusive as sewing (which leaves a series of holes in the material and call allow water permeation) or as labor intensive as RF welding (which necessitates a smaller work/sealing areas due to technical constraints), a properly calibrated heat seal creates a water-tight link between panels that is as strong as the base fabric.
Here at Celina we fancy ourselves fairly knowledgeable about industrial fabrics. From the standard PVC vinyl that is the mainstay of our commercial production lines to tricot and biological/chemical resistant fabrics, we’ve done massive amounts of trial-and-error study and research into sealing and sewing the products.
The Joint Enterprise Research, Development, Acquisition and Production/Procurement (JE-RDAP) program is tasked with supporting the research and development in the field of Chemical, Biological, Radiological, Nuclear, and High-Yield Explosives (CBRNE) items. This includes defense systems, capabilities, equipment, supplies, and general materials that in one way or another are in used in situations that deal with CBRNE circumstances. To fulfill their goal, JE-RDAP occasionally issues contracts for their research efforts.
Insulated Ducting is made with wire reinforcement, keeping the duct in shape no matter where it’s installed. Sandwich ducting has this wire added while the duct itself is being fabricated. This puts the wire within the four layer seams, and can still have wear stripping added for extra protection. Duct-in-Duct is made with a standard wire reinforced duct on the inside, and doesn’t need additional wire on the outside.
