5. What is the Function of Roll Forming Machine in the Production of PIR Sandwich Panel?
An uncoller is a machine used to uncoil the PIR coil using hydraulic power which gets driving energy from the motor.
This also involves the placement of a rubber roller on the top of the uncoller to ensure that the coil does not undergo uncoiling all at once or over uncoil during the process.
This is then followed by a major step in which the sheet is passed through a roll-forming machine for properly shaping the coils.
The roll forming machine has two sub-units; upper and lower roll forming units. The main function of these units is to shape the steel sheet from both sides.
6. Why does PIR Sandwich Panel Production Involve Preheating?
The next step in the PIR Sandwich Panel production is the preheating step. Once the sheet is rolled and shaped, it is passed through the heating process.
A moderate temperature is maintained during this heating to prevent deterioration of the material.
Due to the temperature rise, the steel sheet’s heating process is activated.
This increases the force of adhesion between the steel sheet and the foam ensuring strong bonding between the two.
7. What Happens in the Metering Step of PIR Sandwich Panel Manufacturing?
PIR is then sent to the foaming machine which determinesits quality.
Catalysts are added to this machine, which determines the number of components accordingly.
Special liquid components are mixed in a specific amount and added to the metering machine for the production of polyisocyanate.
8. What is the Purpose of Foaming Portal and Pouring in PIR Sandwich Panel Production?
The mixing head is responsible for the production of oscillations which further help in gaining optimum application of the PIR mixture on the facing layer present on the lower side.
An A.C motor is used for providing energy for moving the mixing head.
This mixing head is further facilitated by a toothed belt which helps in the creation of free oscillating movements that are also programmable throughout the entire panel width.
The operation of the foaming portal is completely noise-free and does not cause any disturbance in the operating environment.
9. How do Heating and Block System Work in PIR Sandwich Panel Manufacturing?
PIR foam is kept between the two layers is chemically treated and cured at a specific regular temperature.
A heating system is used to provide the regular temperature required for this process by producing warm air.
A block system is a unit that prevents the leakage of the PIR Sandwich Panel which helps in the maintenance of the uniform foaming process.
A conveyor helps in the pressing of the foaming pressure and then conveying the PIR Sandwich Panel.
10. What is the Function of a PIR Sandwich Panel Cross-Cutter?
A PIR Sandwich Panel cross-cutter works as a cutting unit. It is used for perfectly cutting the parts used in PIR Sandwich Panel construction.
Talking about its construction, at the rear end of the cross-cutter, a gantry is placed whereas on the right is a saw unit installed.
An important thing here to keep in mind is the speed of the cutter. The speed must be in synchronization with the speed of the conveyer.
The operation of the cross-cutter can be either manual or automatic.
11. Why is a Cooling Conveyor used in Manufacturing PIR Sandwich Panel?
A cooling conveyor is a unit that helps in cooling down the heat present in the PIR Sandwich Panel after it has undergone several reactions generating heat.
This cooling is necessary to bring its temperature equal to the room temperature to avoid any further reactions and deterioration.
12. What are the Applications of a PIR Sandwich Panel?
