Production:

Natural rock, ore and other raw materials, melting in the cupola or other pool kiln (temperature below 2000 ℃), with 50 atmospheric pressure pressure, strong blowing, sudden cooling into fiber. Or dumping method, the molten liquid stream off in the multi-stage rotary rotor, by centrifugal force thrown into fibers, the diameter of the general 3 ~ 9 microns, capacity 50 ~ 200 kg / m ^ 3.

Marine Applications:

‌A-Class Bulkheads & Partitions‌: Primary material for constructing fire divisions between cabins, corridors, and machinery spaces.

‌Hull & Deck Insulation‌: Used as insulation lining on the ship's hull and under decks to prevent condensation and reduce heat transfer.

‌Fire Doors & Dampers‌: Core material for certified fire doors and ventilation fire dampers.

‌Cable Transit & Penetration Seals‌: Used in fireproof cable trays and penetration seals (as indicated by “Cable Panel” in the model table).

Features

‌Unmatched Fire Safety‌: The rock wool core is an inorganic, A-class non-combustible material (meeting B-0, B-15, A-60 standards as per model), providing critical fire resistance to contain flames and smoke, essential for SOLAS compliance.

‌Superior Thermal & Acoustic Insulation‌: The porous fibrous structure effectively traps air, drastically reducing heat transfer and absorbing sound energy, enhancing crew comfort and energy efficiency onboard.

‌Structural Integrity & Lightweight‌: The sandwich construction offers high rigidity and strength while maintaining a low weight, optimizing vessel stability and payload.

‌Durability & Corrosion Resistance‌: The galvanized steel faces protect the core from moisture and corrosion, ensuring long service life in harsh marine environments.
