Polyméthacrylate de méthyleLe poly(méthacrylate de méthyle) (souvent abrégé en PMMA, de l'anglais Poly(methyl methacrylate)) est un polymère thermoplastique transparent obtenu par polyaddition dont le monomère est le méthacrylate de méthyle (MMA). Ce polymère est plus connu sous son premier nom commercial de Plexiglas (nom déposé), même si le leader global du PMMA est Altuglas International9 du groupe Arkema, sous le nom commercial Altuglas. Il est également vendu sous les noms commerciaux Lucite, Crystalite, Perspex ou Nudec.

| Résumé : |
A great future is predicted for microalgae: Whether pharmaceutical, chemical, or foodstuffs industry, new application options keep on arising. Photobioreactors are used to cultivated algae on a large scale. During operation of these systems, the devil lies in the detail – as so often. The Algoliner company has developed a reactor made of acrylic glass, which solves many problems. Extrusion is done directly on a field. |
| Note de contenu : |
- High-tech between strawberries and asparagus
- Pipes as flexible as a hose
- Aseptic flange instead of dead space
- Pigs keep the pipes clean
- A patented suspension system keeps everything in line
- Capturing CO2 where it is produced
- Fig. 1 : The extruder is installed in a truck trailer, and consists of standard components. However, development of the mold proved to be tricky, Hans Väth explains to Plastics Insights editor Susanne Thyrauer
- Fig. 2 : Hans Väth, founder and CEO of Algoliner, demonstrates how light, and above all flexible, the PMMA pipes are, thanks to their small wall thickness
- Fig. 3 : The injection-molded flanges are also made of PMMA, and are chemically welded to the pipes. The resulting smooth inner surface prevents dead spaces in the system
- Fig. 4 : Every pipe has a profile, which enables the flexible pipes to be suspended, and can even be used to mount LED lighting strips, if necessary
- Fig. 5 : The movable suspension permits the PMMA pipes to deflect sideways to compensate the temperature-related linear expansion |
