Second Genaration Pultrusion Machine

Maceration device.

 

Maceration device means to completely impregnate the glass material through a resin paste, curing agent.

Wrapping machine/ Rebar development mechanism (RDM).

 

Wrapping machine is designed for formation of glass material filaments into a tow and winding the filament in a spiral around the beam to create corrugated surface of the product.

 

Heat-treatment chamber/ Polymerization tunnel-like chamber


 

Heat-treatment chamber is used for the polymerization and production of fiber yarn adhesives.

The temperature control panel is used to heat the bonding elements in the molded fiberglass bars to a specific temperature.

The production line is controlled by 7 panels and 7 ovens.

Each panel is divided into two separate independently regulated temperature loops.

Temperature control in each loop is carried out by a temperature controller with PID control and thermocouple.



Cooling chamber.

 

Cooling bath is is used to continuously lower the temperature of the fiberglass bar, and the cold water in the circulation system will not be discharged from the drain.

The water temperature is always in a closed cycle, but the water needs to be changed once after a certain period of time, so there will be no severe temperature shock, cooling chamber will ensure the continuity of the products and enhance their strength

 

Main drive gear/ Pulling mechanism.

 

 

Pulling mechanism is used to pull the rebars at the specified speed and compression pressure.

Since the composite fiberglass bars do not aggregate 100% after the cold water circulation system during production, which means they are prone to crack when overstretched by tension, extrusion devices must be provided for extrusion..

GFRP REBAR

FRP Rebar is a Spiral Wrapped Structural Reinforcing Rod made from a combination of fiberglass roving and resin. Developed as a superior alternative to steel in concrete reinforcement, FRP Rebar is suitable for applications requiring a lightweight material that has high tensile strength, with non-corrosive and non-conductive properties. For example, properly reinforced FRP concrete slabs exposed to heavy traffic, such as bridge decks and driveways, last approximately 20 times longer than conventional methods.
