"Construction of fastener type steel pipe scaffold safety technical specifications" in the page 69 Table c-4 "minimum number 4" how to understand
Extrusion board (XPS board) is the third generation of rigid foam insulation material, from the process it to overcome the complexity of the EPS production process, with EPS board can not replace the superior performance. It is made of polystyrene resin and other additives through the extrusion process has a continuous uniform surface and closed-cell honeycomb structure of the plate, 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. Its mechanical properties are unmatched by EPS, in addition, due to the continuous extrusion caused by the tight closed-cell structure. Its density, water absorption, thermal conductivity and steam permeability are lower than other types of sheet metal, is the market recognized the best insulation materials. It is best to use the density of high point, easy to deformation by the impact of weathering better

Upstairs that is wrong, hot research technology is a hot flow meter, specifically for the vacuum thermal conductivity of the thermal insulation board to test. GB, ASTMC518. Vacuum insulation board VIP is mainly used for insulation, such as household refrigerators, yacht refrigerators, mini refrigerators, car refrigerators, deep freezers, electric water heaters, vending machines, freezers, refrigerated containers, building wall insulation and LNG Storage and transportation.
