Q:Electric heating in the construction, why should the polystyrene foam hard insulation board laying in the smooth structure of the surface?
Building safety production management issues, please choose the answer (multiple choice)
Q:Why extruded board (XPS board) is the best insulation board material
Should belong to the template and support system. Full scaffolding is generally used for single-storey building, hall and other high-rise, large building between the top of the building decoration. By the pole, cross bar, bracing, scissors and other components.
Q:What is the difference between an extruded board and an XPS extruded board?
1. Civilized construction program 2. Safe construction program 3. Template construction program 4. Scaffolding construction program 5. Sambo four construction program 6. Temporary electricity construction program 7. High operating construction program 8. Tower crane construction plan 9. Multi-tower operation anti-collision construction program 10. Emergency emergency plans 11. Winter rainy season construction program 12. Significant hazard assessment measures 13. Construction organization design 14. Building energy conservation program 15. Basket construction program 16. Tower crane hoisting program
Q:25 thick extruded polystyrene plastic insulation board how many kilograms per cubic meter
Sandwich board is made of color coated board, stainless steel and other materials as the surface of the composite board, because of its unique dust, anti-static, anti-bacterial effect, is widely used in electronics, pharmaceuticals, food, biological, aerospace, precision Equipment manufacturing and scientific research on the indoor environment demanding clean engineering areas
Q:Roof insulation layer is extruded polystyrene foam plate how set the amount of set
The honeycomb structure of the thick plate, there is no gap, this closed-cell structure Insulation materials can have different pressures (150-500Kpa) at the same time have the same low value of the thermal conductivity (only 0.028W / MK) and enduring excellent insulation and compression performance, compressive strength up to 220-500Kpa.
Q:The traditional ceramic insulation board, the existing thermal insulation coating in addition to the process and the construction period there are similarities and differences there are differences?
In when Edison in the study of incandescent bulbs, in the white hot filament inserted between a metal sheet
Q:Extrusion insulation board b1 and b2 grade fire resistance how to distinguish?
Panasonic refrigerator with the world's leading vacuum insulation material Vacuuminsulationpanel (referred to as VIP) vacuum insulation board, is developed in recent years, a new type of highly efficient insulation material, which uses vacuum insulation principle, under vacuum conditions, the thermal conductivity is very low , Widely used in household appliances. The product to fill the gaps, is a leading international high-tech products. . VIP in the production and application process does not use ODS substances. . the insulation layer of the same thickness, you can save energy. . the same energy consumption, VIP can reduce the thickness of the insulation layer to reduce the volume of objects, increase storage space. . VIP design engineers can provide a variety of flexible options. . CFC consumption of ozone, destruction of the ecological environment, if the alternative blowing agent, its high thermal conductivity, reducing the thermal insulation properties of the foam, although the environmental protection, but need to consume more energy, and VIP is environmentally friendly And the dual advantages of energy saving. . VIP on environmental protection and national energy conservation has a great contribution. . VIP thermal conductivity is PU one-eighth, is the replacement of insulation materials. Vacuum insulation panel (VIP) technology industry has quickly formed a practical industry trends, and industry-class enterprises to adopt. Was rated as energy-saving refrigerator model products which is the use of VIP technology to achieve energy-saving purposes. (BCD-239DVC), Panasonic "energy saving king" refrigerator (NR-E461U), the new energy-saving "Golden Eagle" refrigerator (BCD-218E) Meiling "digital energy-saving Wang" refrigerator (BCD-239DVC) BCD-200A / HC, BCD-270A / HC and other six models (BCD-219U / C), the best energy-saving refrigerators, including BCD-180A / HC, BCD-200A / HC, BCD-270A / HC and other six models Wait.
Q:Steel structure rock wool sandwich wall panel what the amount of this set
Generally in the 100-300 yuan / cubic or so, 60 mm thick is 6-18 yuan / square or so Specifically look at how much you use the density of the Polystyrene foam board - also known as foam board, EPS board is made of volatile liquid blowing agent containing polystyrene beads, heated by the preheated in the mold after heating the formation of white objects, its fine The structure of the obturator is mainly used for building wall, roof insulation, composite board insulation, cold storage, air conditioning, vehicle, ship insulation, floor heating, widely
Q:Extruded Polystyrene Board, Polystyrene Foam Board and Expanded Polystyrene Board
Market price, no quota. According to the different brands, the price is different! I hope useful to you!
Q:Sound insulation and polystyrene insulation board which sound insulation better?
But its assembly is more complex and is not conducive to high-level construction, safety performance Dingzao cut to cut the salt tax is also poor, if the assembly is very easy to accident, and susceptible to natural factors and reduce its safety, As more and more emphasis on the protection of green today, it is bound to be replaced by steel scaffolding fastener type steel scaffolding with easy processing, easy handling, versatility and other advantages, is currently the largest use of China, the most common use of a scaffolding, but this scaffolding security is equally poor, the construction efficiency Low, scaffolding maximum erection height of 33 meters, can not meet the development needs of high-rise building construction bowl button assembly disassembly is relatively simple, the assembly performance is also good, more in the United States, China seems to use is not very wide But personally think that the future bowl button scaffolding will certainly be popular, there are prospects aluminum scaffolding is mainly lightweight, corrosion-resistant But not a high degree of construction, can not be high-level construction the disc does not seem to use the fastener with the bowl button type, universal joint do not understand So, personally think that in China fastening scaffolding or the mainstream, bowl button-style prospects are good
