Waterproof: In the cold, dry and wet weather, magnesium plate glass is always solid consistent performance, without the impact of condensation of water droplets and humid air, even if placed in water for a few days after removing dry naturally, will not be deformed, soft, normal use will never happen hygroscopic brine back phenomenon. After testing, the board itself without water permeability. Light earthquake: Apparent density 0.8-1.2gcm3, reducing the load of the building, so the building interior weight reduced by more than 60 percent, while increasing the use of an area of ??5-8%. Lightweight structural seismic favor, effectively reducing the cost base and the main structure. Superior strength: 5.1.8 magnesite special phase, clouds fiberglass cloth and good toughness of plant fiber, is the glass magnesium board, although light weight, but compact, good stability, not deformed, with a wood-like toughness, anti- impact on the compressive, tensile and breaking excellent performance, both just tough, bending strength reaches 322kgfcm2 (vertical) and 216kgfcm2 (horizontal), impact strength up to 25MPa environmental health: not contain asbestos, formaldehyde, benzene and other harmful radioactive elements, fire smoke-free, non-toxic, no smell. The material for the production of natural mineral powder and plant fiber, the production process of natural conservation, low energy consumption, no sewage matter, energy saving, the use of the board out of powder-free, its unique natural pore structure, able to adjust the indoor temperature, to make room and office more comfortable. Thermal energy: uniform pores, dense, properties of inorganic materials, thermal conductivity 0.216wcm k, than the sand-lime brick diced 1.1wcm k more insulation, saving energy consumption, to make room to maintain a comfortable environment, fresh?? air. Magnesium composite duct is a new high-tech composite sheet, the product is made of high quality magnesium oxide, magnesium chloride, alkali-resistant glass fiber cloth and an inorganic binder by modern technology roll is made with light weight, high strength, Do not burn, noise, heat, moisture, water resistant, long life and other characteristics, is a new generation of energy-saving, environment-friendly green products. Magnesium composite duct by the State Building Materials Test Center and the national fixed fire extinguishing systems and fire Component Quality Supervision and Testing Center, the physical properties of the technical indicators are in line with the requirements of JC / T646-2006 standard of qualified products, the burning properties of GB8624A level. Magnesium composite duct is mainly used in construction, decoration, fire and other fields, especially for restaurants, hotels, shopping malls and other crowded places decoration and basement, damp environment such as air defense and mine engineering, glass magnesium fire board is to replace all kinds of plywood , MDF, particleboard, gypsum board and other sheet metal replacement products, is a key recommendation of the National Association of decorative green building materials. The main features of magnesium composite duct: 1, superior product quality: Shanghai high plus environmental Ventilation Engineering Co., Ltd. to establish a comprehensive quality management organization and product quality continued to improve the program, in strict accordance with the ISO9001: 2000 quality management system requirements for the production of products, At each stage of the process are set to the control points can be controlled, to ensure product quality. 2, high resistance to strong performance: High High plus brand magnesium duct strength, flexural strength greater than 1.8Mpa, can withstand wind pressure 2500pa meet high, the use of low-pressure air system. 3, the unique moisture resistance: High plus brand magnesium composite duct resistance to high water resistance, in a wet environment does not rust, corrode, even soaking wet, and still maintain the original shape, more than 97% anti-wet strength here . 4, excellent fire performance: High-plus brand magnesium duct made of non-combustible and non-combustible inorganic material composite insulation materials made by the high-tech process, through the National Fire Protection Building Quality Supervision and Inspection Center, identified as Class A non-combustible materials. High plus brand magnesium duct special glue and accessories are Class A non-combustible materials. 5, environmental protection, clean air: High plus brand magnesium composite duct as a new green building materials, from raw materials, process recipe, there are aspects of the production process emissions from energy recovery and other products have taken effective environmental protection measures, Duct whether in production, production, installation or during use not produce environmental pollution substances. The test duct even when burned, it produces smoke also contain toxic substances harmful to humans. Also has no rust, no mildew, no dust, no growth of bacteria, germs, dust and fibers, no odor, no particulate, gas-like pollutants and biological aerosol can improve indoor air quality 6, leakage rate, improve the efficiency of air transport: High plus brand magnesium composite duct used in all imported glue bonding structure is made flangeless connection, greatly improving the tightness of the duct, pipe compared to metal wind, reducing the seams and flange leakage, reducing duct leakage rate, improve the efficiency of air transport, air leakage rate plus brand high magnesium composite duct leakage rate is far below the metal duct. 7, good insulation properties, reducing the energy consumption of heat transfer: high plus brand magnesium composite duct direct recombination of insulation materials, no secondary insulation, duct small thermal conductivity, excellent thermal insulation properties, reducing the hot and cold air transportation process loss of heat conduction. 8, wind resistance and reduce friction loss: high plus brand magnesium composite duct mechanized production, smooth surface, low friction coefficient, low drag, duct surface roughness absolute minimum. 9, long life, save and invest: High plus brand magnesium composite wind pipe product design reasonable structure, reliable performance, stable quality, the service life of over 20 years, several of the cost savings to customers on investment (above the Shanghai Jian Sheng Construction Engineering Co., Ltd. published) declined counterparts theft, you are welcome to inquire, I promise: quality assurance! Excellent and inexpensive price! Honesty!
