Siding Composition

CNBM Siding consists of three layers: the top material isspecial aluminum-zinc coated metal board, the core material is rigidhigh-density Polyurethane foaming with fire-retardant treatment, and the backmaterial is fiber foil paper.

Product Features

Since CNBM Siding itself has the characteristics ofinsulation, water-proof and fire-retardant, lightweight anti-seismic,convenient construction, sound insulation and lower noise, environmentfriendly, and lasting beauty etc., in the meanwhile since its assembly methodof its siding body is simple and practical, without being limited by theseasons and environment, the installation is very safe and convenient, suitablefor four seasons.

Extensive Application Scope

CNBM siding is not only suitable for the newly set upbrick-concrete structure, framework structure, steel structure, lightweightbuildings, but also perfect for energy-saving reconstruction of the oldbuildings.

Q: What is the acceptance criteria for rock wool sandwich panels?: 1) upper and lower surface: the use of galvanized color steel plate, the thickness of 0.4-0.8mm. According to the specific requirements of customers, can also be used galvanized steel or galvanized steel plate. The steel plate is first molded by a molding machine and is compounded with the rock wool factory. ? 2) Yanmian core material: the use of density of 120kg / m yan rock block staggered laying, the fiber perpendicular to the sandwich plate on the upper and lower surfaces, and close contact to enrich the sandwich panel of the entire vertical and horizontal. The combination of rock wool and rock wool and the upper and lower steel plates through the high-strength foaming agent to form a whole, sophisticated production process to ensure that the high-density rockwool insulation and metal plate between the inner wall can produce poles Strong adhesion, so that the rock wool sandwich panel has a very good stiffness. ? Wujiang City Linxue purification Choi Board Co., Ltd. is the China Electronics Society Clean Technology Branch members. Commitment to various types of purification decoration, clean air-conditioning works, hydropower engineering facilities supporting the design, installation, commissioning through-train service.

Q: Sandwich board is how the synthesis: Should be "sandwich board" was right. Sandwich panel products are composed of two layers of metal panels (or other material panels) and directly in the middle of the panel foam, mature molding of the composition of the polymer core insulation. These sandwich panels are easy to install, lightweight and efficient. Filling system is also used to close the molecular structure, you can put an end to the condensation of water vapor. The forming of the outer steel sheet takes into account the structural and strength requirements, and takes into account the appearance, the inner layer is formed into a flat plate to suit various needs. Sandwich panels for large industrial plants, warehouses, gymnasiums, supermarkets, hospitals, cold storage, activities, building plus layer, clean workshop and the need to heat insulation fire places.

Q: The Development Trend of Color Steel Sandwich Board: Caigang sandwich board not only has high mechanical strength of steel, easy to shape the performance, but also both good decorative coating materials and corrosion resistance. Color steel sandwich panels are respected in today's world of emerging materials. With the progress of science and technology, environmental awareness, the improvement of people's living standards, Caigang sandwich panel activities room more and more show a strong vitality and broad market prospects, by the construction, home appliances, electrical and mechanical, transportation, interior decoration , Office appliances and other industries of all ages. Caigang sandwich panels used in the core of the main phenolic foam, polystyrene, extruded polystyrene, rigid polyurethane, trimer and rock wool, etc., and phenolic foam has excellent fire insulation properties, other materials can not be replaced , For example: phenolic foam insulation effect is more than 2 times the polystyrene, fire performance is also higher than the polyurethane, polyurethane combustion will release the hydrogen cyanide-rich smoke. With the country's attention to building fire and the introduction of relevant laws, I believe that phenolic color steel sandwich panels will create a blue sky in the construction field.

Q: What is the rigid polyurethane sandwich panel: This is a Caigang sandwich panel, can be used as a roof structure of the roof and wall panels, with a large stiffness, than the pressure plate stiffness, thermal performance is also very good, and the polyurethane sandwich panel fire Performance is also good

Q: Rock wool sandwich panel product parameters: Upper / lower plate thickness 0.4 ~ 0.8mm color steel / electric, hot galvanized sheet / stainless steel plate Core (Mine) rock wool capacity of 120 ~ 150kg / m thickness: 50-150mm Side seal steel strip or no side seal steel strip : 0.4mm ~ 0.8mm galvanized sheet Effective width of the mouth 950mm, 1150mm; thickness 40mm ~ 150mm; length is not limited Board protection form PVC protective film

Q: Whether the rock wool sandwich panel can replace the firewall for fire partition separation: Can not. The fire resistance of the firewall is not less than 3 hours. And rock wool sandwich board fire resistance up to only 2 hours. With rock wool sandwich panel replacement, the equivalent of reducing the fire rating. The above is a personal opinion.

Q: EPS sandwich panels, PU sandwich panels and rock wool sandwich panels of the sound effects which is good?: Rock wool sandwich panels are the most suitable

Q: Does anyone know the reason why the sandwich panel is bubbling and partially degumming during the pressing process?: Italian Prith hydraulic press gives the solution: 1, control the moisture content of the board in the range of 8 to 12% 2, control the amount of coating in line with process requirements 3, buck the second stage of the speed should be slow, hot pressing temperature should be appropriate to reduce 4, check the resin quality 5, the appropriate extension of hot pressing time Italy Pride & OKorder Ding Di CNC Equipment Co., Ltd., we have sufficient technical sales and administrative staff in the world to provide you with even the most challenging press engineering application solution for our customers. Provide spare parts replacement and factory direct on-site service to ensure that your satisfaction, so that your production operations at a moment of profitability.

Q: Polyurethane sandwich panels in the polyurethane is what material, what are the benefits of industrial building materials should choose polyurethane?: Polyurethane is a two-component AB material (isocyanate and combined polyether) mixed foam, is the thermal insulation material in the lowest thermal conductivity of 0.017 ~ 0.024 (thermal conductivity of the lower the better insulation). Polyurethane sandwich panels used in the filling process of polyurethane, pre-made pre-insulation board directly installed on-site use. If your plant area is relatively large, it is recommended that you only use the whole color plate, and then use the field of polyurethane spray foam process, this process than the infusion process is the advantage of spraying seamless, better insulation. The cost is still lower than the infusion process.

Q: Lightweight insulation color steel sandwich board clip what the core: Color steel plate sandwich material is divided into foam color steel plate (chemical name for the polystyrene color plate), rock wool color plate, polyurethane color plate, paper honeycomb sandwich panels, glass wool color plate.
