Typical Projects: Building firewalls, industrial plant cable shafts, office building emergency stairwells

 

Building Exteriors: Focus on "Weather Resistance + Lightweight + Low Efflorescence" for Outdoor Adaptation

1. External Wall Insulation Integrated Substrate

Core Applications: Face/back panels of external wall insulation composite boards, base materials for real stone paint/imitation stone paint finishes

Adaptation Reasons:

Strong weather resistance (stable at -40℃ to 120℃), withstanding ≥50 freeze-thaw cycles, suitable for extreme climates in northern and southern regions;

Low efflorescence prevents white staining and finish peeling after rainwater immersion;

Lightweight design (50% lighter than cement boards) reduces external wall construction difficulty and keel load pressure.

Typical Projects: High-end residential external walls, commercial complex curtain walls, industrial park factory external walls

 

2. Outdoor Enclosures & Decoration

Core Applications: Balcony railings, equipment room external walls, walls, landscape corridor enclosures

Adaptation Reasons:

Wind load and UV resistant, maintaining shape and color after long-term exposure to sun and rain;

Insect, termite, and decay resistant, eliminating the need for regular maintenance and repainting, reducing outdoor maintenance costs;

Directly paintable or claddable with wood/stone-like finishes, balancing functionality and aesthetics.

Typical Projects: Community balcony railings, commercial park walls, landscape corridor enclosure walls

 

Special Scenarios: Focus on "Low Corrosion + Low Smoke Non-Toxic + Customization" to Break Traditional Limitations

1. Steel Structure Buildings

Core Applications: Fire protection cladding for steel structure beams/columns, base material for steel keel partition walls

Adaptation Reasons:

No free chloride ions, zero corrosion to steel components, extending steel structure service life by 30 years compared to magnesium chloride boards;

Lightweight feature avoids increasing steel structure load and structural reinforcement due to board weight;

Fire resistance rating ≥2 hours, meeting the requirement of "over 1.5 hours of fire protection for steel structures".

Typical Projects: Steel structure factories, steel-framed office buildings, prefabricated steel structure residences

 

2. Transportation & Marine Vessels

Core Applications: Rail transit carriage interior panels, marine cabin partition walls/ceilings

Adaptation Reasons:

Low smoke and non-toxic, complying with international safety standards such as IMO (marine) and EN 45545 (rail transit);

Moisture and fire resistant, suitable for high-humidity marine environments and enclosed rail transit spaces;

Lightweight and high strength, reducing transportation weight and improving energy efficiency.

Typical Projects: High-speed rail/subway carriage interiors, ocean cargo ship cabins, ferry partition walls

 

3. Fire Doors & Custom Furniture

Core Applications: Fire door core materials, high-end cabinet back panels, custom furniture base materials

Adaptation Reasons:

Lightweight design (25% lighter than traditional core materials) reduces fire door weight and extends hinge service life;

Moisture and insect resistant, formaldehyde-free, suitable for furniture in humid environments such as kitchen cabinets and bathroom vanities;

High strength and deformation resistance, serving as load-bearing base material for custom furniture, replacing multi-layer boards and density boards.

Typical Projects: Class A/B fire doors, high-end cabinets, bathroom vanity back panels

 

4. Special Industrial Scenarios

Core Applications: Chemical workshop partition walls, data center room enclosures, cold storage partition walls

Adaptation Reasons:

Strong chemical corrosion resistance (withstanding weak acid and alkali environments), suitable for chemical workshop working conditions;

Fire and moisture resistant, no dust shedding, meeting "clean + safe" requirements for data centers;

Excellent thermal insulation performance (thermal conductivity 0.12-0.18 W/m·K), reducing cold storage energy consumption.

Typical Projects: Chemical park factories, data center machine rooms, food cold storages

 

Export/International Projects: Focus on "Compliance + Environmental Friendliness + Multi-Standard Adaptation" to Break Trade Barriers

1. EU/North American Market Projects

Core Conclusion

The applicable scenarios of sulfate-based MGO boards essentially boil down to "where there is demand for fire resistance, moisture resistance, environmental friendliness, and lightweight, there is their value". They not only cover the interior and exterior of ordinary buildings but also break the limitations of traditional boards in humid, corrosive, and international scenarios. Particularly suitable for high-end projects with strict requirements for quality, safety, and compliance, their characteristics of "full-scenario adaptation + low whole-life cycle cost" make them the preferred building material to replace gypsum boards, magnesium chloride MGO boards, and cement boards, as well as a "customized solution" for high-end buildings and special scenarios.
