In today's era, with the improvement of people's safety awareness, more and more buildings, vehicles, public facilities and other scenarios have laid out passive fire protection systems, such as in factories, the purpose of passive fire prevention is to protect critical processing and safety equipme

Nano Microporous Insulation is made from silica particles which diameter is only dozens of nano ,with Infrared sunscreen and fibers together .After series of physical and chemical reaction ,we got the Nano Microporous insulation materials ,there are lots of nanopores in it .What is the characteristi

The elevator refractory heat-insulation door is the elevator plus a \"heat-insulating fire door\". If such a fire-resistant insulation door is installed in the elevator hall of the high-rise building, it will be very beneficial to delay the fire through the wellway through the wellway during the fire. It is conducive to the limitations of the trapped person to fire, heat and smoke, and save the life of the trapped person. Therefore, the fire-fired gate door is of great significance for the safety of the person's life and prevents the spread of fire.

In the cold winter, building roof and wall insulation have become the focus of attention. At present, nearly 2 billion square meters of new buildings are newly built every year in my country, which is more than the total construction volume of all developed countries, but more than 95% of buildings
