Medium Crystal Panel

Board Structure

The Zhongjing board features a homogeneous, solid, one-piece structure, free of delamination, hollow areas, and laminated layers. The overall material is uniform and consistent, ensuring a stable structure that does not detach or powder:

1. Inorganic Substrate: Magnesium-based cementitious material forms the core of the board, guaranteeing fire resistance, water resistance, and high strength.

2. Plant Fiber Reinforcement Layer: High-quality plant fibers are incorporated to enhance the board's toughness, overcoming the brittleness and cracking issues of traditional inorganic boards.

3. Modified Stabilizing Layer: Special modifying agents are added to prevent efflorescence, blooming, and deformation, improving the board's weather resistance and stability.

Production Process

Precise Raw Material Proportioning (Magnesium Oxide + Magnesium Chloride + Plant Fiber + Modifier) → Fully Automatic Mixing and Emulsification → Material Laying and Leveling → High-Pressure Roll Forming → High-Temperature Curing and Maintenance → Constant Temperature Color Stabilization Treatment → Double-Sided Precision Sanding → Cutting to Length → Quality Inspection and Sorting → Packaging and Warehousing

Core Performance Characteristics

✅ Core Advantages

1. Class A Non-Combustible Fireproof: Pure inorganic material, non-combustible, smokeless, and non-toxic, with a high fire resistance limit, fully meeting the fire safety acceptance standards for large-scale industrial projects and public places, far exceeding the B1 fireproof rating of wood-based panels and SPC boards.

2. Completely Waterproof and Moisture-Proof: Completely non-absorbent, non-dampening, non-moldable, and non-deformable, with a water absorption rate approaching 0, suitable for long-term use in basements, high-humidity coastal areas, and damp kitchens and bathrooms, completely solving the problems of gypsum board powdering due to moisture and wood board mold bulging.

3. Zero Formaldehyde and Ultra-Environmentally Friendly: The entire production process is glue-free and free of harmful additives. Made from natural inorganic raw materials, it is formaldehyde-free, benzene-free, and odorless, making it a mother-and-baby grade environmentally friendly board material, ready for immediate occupancy after installation.

4. Extremely High Stability: With an extremely low coefficient of thermal expansion and contraction, it will not crack, warp, or deform even in environments with alternating wet and dry conditions and large temperature variations, superior to plywood, particleboard, and ordinary calcium silicate board.

5. Good Toughness and High Strength: The fiber-reinforced structure combines hardness and toughness, resisting impact, pressure, and bending. It is not prone to chipping or breaking and can be directly cut, drilled, and grooved.

6. Sound and Heat Insulation: The high-density solid structure with uniform internal micropores provides excellent sound and heat insulation performance, effectively reducing indoor noise and stabilizing room temperature.

7. Corrosion-Resistant and Insect-Proof: The inorganic material does not breed bacteria, attract insects, or corrode, resulting in a lifespan far exceeding that of wood-based boards.

⚠Disadvantages

1. Slightly heavier than wood-based panels and SPC wall panels, requiring reinforced framing for large-area ceiling installations to avoid structural damage.

2. Higher hardness makes hand-cutting more difficult than ordinary gypsum board, requiring specialized cutting tools and demanding higher workmanship.

3. Higher unit price than gypsum board and particleboard, resulting in a slightly higher overall renovation cost; less cost-effective for low-cost, simple commercial projects.

Applicable Scenarios

Recommended Application Scenarios: Hotel and guesthouse partition walls and ceilings, schools and hospitals, office building decoration, shopping malls and public places, clean rooms, basement moisture-proofing projects, decoration in coastal high-humidity areas, interior wall panels for container houses, interior decoration for makeshift hospitals, kitchen and bathroom wet and dry area partitions.

Key Selection Points

1. Check the flatness of the board surface: High-quality Zhongjing boards are smooth and flat on both sides, without bumps, sand marks, or cracks, and the surface is clean and uniformly white; inferior boards are dark in color, rough in surface, and have impurities and black spots.

2. Check the density of the substrate: The cut surface is tight and delicate, without voids or loose debris, and produces a crisp and clear sound when tapped; inferior boards have a loose cut surface, produce a dull sound when tapped, and are prone to powdering.

3. Test the waterproof performance: In a drip test, the board surface does not absorb water, does not penetrate, and leaves no water stains; it does not swell or mold even after long-term immersion.

4. Verify the qualification report: Legitimate products have an A-level fireproof test report, a formaldehyde-free environmental protection test report, and moisture and corrosion resistance test qualifications, making them suitable for project acceptance and foreign trade customs clearance.

5. Thickness and Application Considerations: 6-9mm is preferred for ceilings, 10-12mm for partitions, and 15mm or thicker boards are recommended for heavy-duty and high-humidity projects.

Export-Related Notes

1. Zhongjing boards are pure inorganic non-metallic boards, containing no wood or wood fibers, completely circumventing EU DR and US Lacey Act timber traceability controls. Exports to Europe, America, Australia, and Southeast Asia do not require timber legality traceability, facilitating customs clearance.

2. Core Export Testing Items: Class A fire resistance test, RoHS environmental protection test, formaldehyde-free test, salt spray moisture resistance test, and board strength and compressive strength test.

3. Product Advantages: Suitable for high-end overseas commercial projects, guesthouses, hotels, container houses, and medical purification projects. Fire resistance and environmental protection properties meet European and American import standards, giving it strong market competitiveness.

4. Transportation Precautions: Due to the high hardness and brittleness of the boards, corner protectors and reinforced packaging are necessary during transportation to prevent damage to edges and corners.
