Строительная сэндвич-панель

Building sandwich panels combine a polypropylene honeycomb core with outer skin layers, typically Continuous Fiber Reinforced Thermoplastic (CFRT) sheets. The honeycomb structure, approximately 95% air, delivers exceptional strength-to-weight ratios while maintaining structural integrity across temperatures from -40°C to +80°C.

The polypropylene core fuses to skin layers through glue-free bonding under heat and pressure, eliminating adhesives. CFRT skins may include multiple unidirectional tape layers and protective films for enhanced bonding and scratch resistance. Panels resist moisture, corrosion, and chemicals while remaining fully recyclable.

Available thicknesses range from 5mm to 120mm, with maximum dimensions reaching 2.8 meters wide by 12 meters long. Core densities typically span 60-100 kg/m³, with compressive strength values from 1.47 to 2.6 MPa. The thermoplastic nature enables CNC machining, thermoforming, and bending without delamination concerns.

Applications include commercial vehicle bodies, mobile homes, transportation flooring, marine decks, architectural partitions, and building formwork. Surface treatments offer glossy or matte protective films, embossing, and custom paint coatings. UV protection through carbon black additives maintains mechanical properties in outdoor environments.

At RaxPanel, our engineering team manufactures high-performance composite panels to deliver durable, moisture-resistant, and energy-efficient solutions for industrial and commercial projects worldwide.

💡 Профессиональный совет: Предотвращение расслоения при термических циклах
В RaxPanel мы используем автоматизированное вакуумное ламинирование с высокоэффективными двухкомпонентными полиуретановыми клеями для обеспечения прочности связи, которая поглощает разницу термических расширений без микрорасслоения.

1. Как выбрать правильную сплаве оболочки и толщину

Выбор наружной оболочки определяет сопротивление механическим ударам, защитные барьеры от коррозии и конструкционную жёсткость в различных условиях эксплуатации.

2. Насколько хорошо ядро изолирует и выдерживает тяжёлые нагрузки?

Материал ядра принимает сдвиговые напряжения и сохраняет тепловую изоляцию R-value в диапазонах рабочих температур:

Показатель эффективности	Инженерный стандарт RaxPanel	Преимущество для применения
Спецификация наружной обшивки	Pre-Painted Aluminum / GRP Sheet (0.3mm – 2.0mm)	Высокая прочность на растяжение и коррозионная стойкость
Теплопроводность	~ 0.020 – 0.038 W/m·K	Стабильное значение R и энергосбережение
Клеящий состав	Двухкомпонентный полиуретановый / эпоксидный адгезив	Delamination-free performance under freeze-thaw cycles

3. Какое покрытие поверхности обеспечит защиту ваших панелей на 20+ лет?

Заводское полимерное покрытие обеспечивает долгосрочную стабильность цвета, УФ-защиту и стойкость к промышленным загрязнениям или морскому солевому туману.

Часто задаваемые вопросы (FAQ)

1. What are the standard panel thicknesses, maximum lengths, and width options available for Building Sandwich Panels?

Стандартные толщины панелей варьируются от 10 до 150 мм. Стандартные ширины составляют 1000 мм, 1220 мм и 1500 мм, при этом максимальная длина одного листа достигает 5800 мм (5,8 м) для соответствия габаритам контейнерных перевозок морским транспортом.

2. What are the primary engineering benefits of using Building Sandwich Panels?

Building Sandwich Panels deliver an exceptional stiffness-to-weight ratio, rot-proof moisture resistance, reliable thermal insulation, and dynamic fatigue endurance for high-stress applications.

3. How do these composite panels perform under high humidity and outdoor weathering?

The closed-cell core prevents water logging and condensation absorption, while pre-painted skins provide a 20+ year weatherability barrier against UV degradation.

4. What fire safety ratings and quality certifications do these composite panels meet?

Flame-retardant formulations meet EN 13501-1 Class B-s1,d0 and GB8624 Class B1 fire performance standards. Manufacturing quality is governed under ISO9001 management systems, with raw material performance verified under SGS and CE testing.

5. What surface coating options are available for exterior UV protection?

70% PVDF Fluorocarbon Coating PVDF coating provides a 20+ year exterior weatherability warranty against UV fading and acid rain. FEVE offers high gloss retention, while PE coating is cost-effective for indoor partitions.

6. Can these composite panels be CNC grooved, bent, or edge-sealed on-site?

Yes. Pre-painted skins can be V-grooved at 90° or 135° on the reverse side using standard CNC routers or hand tools, allowing manual edge folding into architectural cassettes without surface paint cracking.

7. How are large panel shipments packaged to prevent freight damage during ocean transit?

Panels are packed with protective PE film on both skins, separated by inter-sheet foam layers, and secured on heavy-duty export wooden pallets or CKD steel crates to prevent shipping damage during 20ft and 40ft container freight.
