The new lightweight composite protective equipment (fireproof airtight doors, airtight doors) jointly developed by the company and the Fourth Design and Research Institute of the General Staff has filled the current gap in domestic civil air defense equipment and is a national patent product. The company strictly implements: and quality management system management standards, strict inspection, reliable product quality and guaranteed after-sales service. It is a revolutionary change in the civil air defense engineering protective equipment industry. The product uses composite materials
It is produced using the molding process. The product has good sealing performance and has the advantages of light weight, high strength, corrosion resistance, long life, as well as good insulation and sound insulation. and flame retardancy. The product is also energy-saving and environmentally friendly, has no maintenance costs
, is easy to install, saves time and labor, and can play an important role in civil air defense construction. Other civil air defense equipment produced by the company include: reinforced concrete protective equipment, steel structure manual protective equipment and valves, as well as various models and specifications
Products that have won the needs and satisfaction of users.
, light weight, high strength
The material of the light civil air defense door leaf is low pressure molded fiber reinforced sheet mold composite material, which is light weight and high strength. Compared with the same specification of civil air defense door, the light weight of the light civil air defense door leaf is reduced by %. The above anti-explosion test proves that the strength of light civil defense doors fully meets the standards.
, Long corrosion resistance and long service life
The light civil air defense door is made of polymer thermosetting fiber reinforced sheet mold composite material, which has a certain ability to resist acid, alkali and other chemicals. The light civil air defense door can be used in the humid environment of the basement all year round. It will not rust or rot and has a service life of more than 10 years
Therefore, lightweight civil defense doors are an excellent substitute invented by traditional people.
, easy to install, maintenance-free
The light civil air defense door lock adopts a four-link driven slide bolt lock, which is light in weight, simple in structure and easy to operate. Compared with traditional reinforced concrete and steel structure protective equipment, it is lighter in weight and easier to install. In addition, the surface of the door leaf adopts a low-temperature baking process to avoid maintenance.
, Other advantages
Light civil air defense doors also have many advantages such as high productivity, good insulation, sound insulation, flame retardancy, moisture resistance and beautiful appearance.
