China's "Shenzhou" spacecraft return cabin insulation raw material manufacturer
High-performance resin and composite new material industry
The high-performance resin industry is the company's traditional pillar industry, which mainly includes three major types of multi-series products, including furan resin-based casting materials, phenolic resins, and special epoxy resins.
The production and sales of furan resin are among the highest in the world, with an annual production capacity of 100,000 tons. It is widely used in the production of castings for automobiles, ships, aircraft, wind power, general machinery, precision instruments and other high-end precision castings. The company has more than 100 casting material products represented by furan resin, ceramic filters, risers, etc., and provides customers with multi-functional and comprehensive integrated solutions. The products are exported to more than 40 countries and regions. One of the world's largest suppliers of foundry materials.
The annual production capacity of phenolic resin is 400,000 tons, and the market is broad in the fields of refractory materials, friction materials, thermal insulation materials, coated abrasives, insulation materials, tire rubber, aerospace, military industry and other fields. The company is a manufacturer of raw materials for the insulation of the return space of the "Shenzhou" series spacecraft and the drafting unit of phenolic resin standards for refractory materials in China. The products are exported to more than 50 countries and regions, becoming the world's major supplier of phenolic resins.
Special epoxy resin is produced by advanced epoxy resin production technology and DCS fully automatic distributed control system. The cured product has excellent heat resistance, chemical resistance, humidity resistance, excellent electrical insulation and adhesion, and is suitable for EMC electronic packaging materials, copper clad laminates, electronic inks, high heat-resistant laminated composite materials, and High temperature adhesives and other fields.
SQ is committed to being a leader in China's new materials and achieving rapid development of new composite materials. Anteford phenolic foam exterior wall insulation board developed based on the phenolic resin industry has the advantages of light weight, good thermal insulation, flame retardancy, low smoke, and no dripping, which has promoted the green, energy saving, safety, Environmental protection development.
SQ light core steel produced by phenolic resin and reinforcing fiber through a special process, has light weight and high strength, sound insulation and noise reduction, flame retardant insulation, corrosion resistance and weather resistance, and has been successfully applied to the track represented by the "Fuxing" high-speed rail The transportation field is seeking applications in new energy vehicles, aircraft, military and other fields.
Light Core SteelTM New Composite
A lightweight composite material made of modified phenolic resin as the main binder, flame retardant reinforcing fiber and other auxiliaries.
Applications
Air duct
Light core steel products can be used as interior decoration and structural materials. They have been widely used in the main air ducts and branch air ducts of railway trains to provide strong support for their weight reduction and fire safety, and to provide more secure and reliable guarantees for vehicle speeding.
Roof
Middle roof panel and side roof panel: The structure of pre-diffuse sandwich core light core steel is used for hot-press forming to produce flat and different shaped profiles to meet the needs of different shapes of middle roof panel and side roof panel. It can also be combined with phenolic SMC to achieve corner positions where molding is difficult. It not only guarantees the light weight of the product, but also meets the requirements of fire prevention, and can realize different thickness and density products according to requirements.
Subway train skirt
Existing solution: unsaturated hand-laminated FRP sandwich light core steel.
Case: Suzhou Line 2 and Suzhou Line 1 increased purchases, and Hexi increased purchases.
Improvement scheme: directly using prepreg pressing, you can make different radians
Floor
According to different requirements, the light-core steel M composite plate can be compounded with FRP, aluminum plate, plywood, etc. The core layer of light-core steel can be tiled or vertical; it can also be used directly with high-density light-core steel, no other The surface layer can be directly nailed and inlaid with structural parts.
Light core steel flooring is a new application range of light core steel composite materials. Because of its excellent FST performance and superior quality-strength ratio, the surface layer can be designed according to product requirements. The core layer is low density light core steel, which can be customized according to customers. For compression, flat drawing and heat insulation requirements, the core layer density is adjusted. The density range is generally 160 ～ 800kg / m3
