Foam glass tube

　　Foam glass is a glass as main raw materials, adding suitable amount of foaming agent, through high temperature tunnel kiln roasting heating and annealing cooling obtained after processing, independent closed with uniform air gap structure of new inorganic thermal insulation materials. Because it is completely retained the inorganic glass chemical stability, low bulk density, small coefficient of thermal conductivity, permeability, water absorption, not burning, not mildew to change, not affected by the rat tooth, high mechanical strength and easy processing, chemical erosion ability all except hydrogen fluoride.
　　Foam glass not only itself is nontoxic, stable chemical performance, and can in turn to high temperature and wide temperature range didn't spoil the good heat insulation performance, and itself and moistureproof, fire prevention, anti-corrosion effect. It in low-temperature cryogenic, underground, open-air, flammable, easy tide and chemical erosion and other harsh environment use, not only safe and reliable, and durable, has been hailed as "the permanent insulation does not need to change".
The main use is as follows:
1, petroleum chemical industry: response equipment, chemical pipeline, oil pipeline, liquefied natural gas pipelines, storage tank foundation, liquefied petroleum gas pipeline.
2, construction, cold storage, shipbuilding, roof insulation, both inside and outside wall heat preservation, parking lot, screen, environmental protection inside the chimney lining insulation.
3, underground engineering, subway, tunnels, underground warehouse. 4, other industries: national defense war industry, grinding foot stone, brick teppanyaki cleaning, air separation equipment of low temperature pipes, cryogenic liquid storage tank, basic insulation.
Specifications:
1, plate: 610 * 457 * (30 ~ 152) mm.
2, piping, equipment sealing cap and special products, can help processing according to the requirements of customers.
In wall insulation foam glass has the following features:
1. Light weight, moisture permeability, water absorption;
2. The coefficient of thermal conductivity small and stable, no combustion;
3. Non-toxic itself does not produce any toxic gas, is completely harmless to the human body fire protection building materials, national fireproof construction quality supervision and inspection center identified as "a-class fire protection building materials";
4. High mechanical strength, easy cutting processing, can use normal woodworking saw the scene on-demand cutting;
5. Stable performance and expansion shrinkage rate is close to cement and steel, very suitable for cement and caigang the structure of the heat preservation material;
6. Resistance to chemical corrosion (except hydrofluoric acid), do not contain any fabric, CFC, as is completely environmental inorganic materials;
7. High compressive strength, is a cold insulation material and thermal insulation material, can withstand the roof parking, building, air terminal and cold storage and so on building roof and heavy load on the ground;
8. Not mildew, prevent rodents, insects, bacteria biological damage;
9. Affected by the temperature change one of the smallest insulation materials, can adapt to the cryogenic to higher temperature range (200 ℃ ~ + 450 ℃).
10. The elder will not use bad, can improve the surface of the wall base and crack resistance;
11. Good heat preservation effect: 26 mm thick foam glass heat insulation brick is equivalent to 250 mm wall heat preservation effect.
Foam glass insulation fire belt system
Since most of the current wall thermal insulation system with organic material thermal insulation layer could not reach the requirements of the national a-class non-combustible firefighters: during A fire can produce such as: the collapse of the whole metope, produce poisonous gas, and many other problems. In this context, it puts forward the solution to fire belt, and in many fire prevention materials, only foam glass can achieve the requirement of fireproof and heat preservation.
