Today, the fireproof filling material manufacturer introduces the steps of pouring fireproof materials into fireproof windows:

1, take the material: according to the volume ratio of the raw materials, the vermiculite or perlite for the puffed treatment of vermiculite or perlite;

2. Mixing materials: mix the above raw materials with a mixer at high speed for 510min, and mix them evenly;

3. Infusion: inject the evenly stirred materials into the aluminum alloy empty pipe through a high-pressure pump, and seal the nozzle with a shaped rubber plug after filling;

4. Drying: The molded product shall be cured at room temperature for 4 hours and dried at 110 ℃ for 6 hours. The invention saves a large amount of material cost by pouring fireproof slurry into the aluminum alloy pipe of doors and windows, and also greatly improves the fireproof effect.
