Plate Types

SALAMANCA Plate:

VALLADOLID Plate:

• Salamanca plate: flat plate with 2 interior ribs for securing light accessories without loss of water-tightness.

• Rapid mounting of flanges and manholes on site.

• Weight of the plate depends on Ø and height. Max weight: 600kg/plate.

• The Valladolid plate is specifically for settling tanks with a channel to be filled with self-levelling concrete.

• Decanter incorporated into plates.

• The Valladolid plate is highly resistant to buckling, thanks to the reinforcement of the isothermal body: whichallows to carry the weight of the bridge.

• Clean and hygienic settling tanks, easy to install and maintain.

• Weight of the plate depends on Ø and height. Max weight: 125kg/plate.

7

Plate Types

BURGOS Plate:

• Has a cellular structure in composite materials,ribbed, which increases its thickness by an additional 45 mm.

• The PUR foam covers the entire plate exceptthe screws and washers.

• Enhanced thermal insulation.

• Vertical load bearing capacity, for example:floating aerator moorings, walkways, buried tanks or tanks inside tanks with different levels of liquid.(Ask our engineering department about your case).

• Possibility to fasten and secure elements onthe entire interior surface of the plate.

• Optional Degasifier: clean water outlet fromsettler via overflow incorporated into the plate.

• Optional Air Pipe: ingress and egress ofblower air through the plate ascending and descending inside the same.

• Weight of the plate depends on Ø andheight. Max weight: 800kg/plate.

Fabrication Process

Flex Molding Fabrication Process:

The Flex Molding process is used to obtain reinforced plastic pieces with high glass fiber content, arranged in the direction of the stress, which leads to high mechanical strength.

It consists of injecting a reactive polymer under pressure into the mold which contains the reinforcement in form of fibers, all of which is done in a controlled vacuum environment.

This process of impregnation (Flex Molding) is used to build pieces in a closed mold, making it an ecological process by eliminating emissions and consumables.

It comprises a mold and a die that performs the sealing with the main mold, a vacuum being created between the two to be able to eliminate the air content. The impregnation of resin is achieved by a pressure difference between the injection and venting points inside the mold. The resin enrichment means that the composite has high external and internal protection against chemical agents.

(For strength and specialty chemicals production temperatures in vinylester)

Composition of the plate from inside to outside:

• Chemical barrier achieved with:- Isophthalic Top Coat, 600 microns (nautical quality). Treated towithstand UVA.

- Glass cap of 1 mm 150 gr/m2, special isophthalic resin enrichmentin Stratified with high content in high-tensile glass using isophthalic resins.

• Laminated high glass content of high tensile modulus performedon isophthalic resins.

• External chemical barrier: isophthalic Gel Coat 600 microns (nauticalquality). Treated to withstand UVA.

The isophthalic resin is authorized for foodstuff applications, such as drinking water for example. Vinylester can be applied on the inside sheet in case of specific liquids or high temperatures.

Other materials utilized:

Standard screws in galvanized steel headed into the tank inner side covered with polypropylene and external part with polypropylene cap.

Gasket of EPDM, ethylene propylene diene monomer or EPDM rubber, an elastomer that offers good resistance to friction and wear. Good resistance to atmospheric agents, acids and alkalis, and chemical products in general. The working temperature varies between -40 and 130 °C.

Screw-Tank sealing according to project specifications or tank contains. Sealed with mastic based polyurethane or nylon gasket.

Nylon has a temperature range from -40 to 90 °C; high mechanicalresistance, good fatigue resistance, high damping power, good sliding properties, outstanding wear resistance and self-extinguishing.

Internal PUR cores as in the Burgos Plate and Valladolid Plate.

High resistance and self-levelling mortar with low contraction coated with elastic non-harmful paint.
