Effect of pressure holding time of extraction process on thermal conductivity of glassfiber VIPs

Structure of vacuum insulation panel in building system

“…New Material Co. Ltd. The general manufacturing process of glass fibre VIP core material has been reported elsewhere [12,16]. In addition to the reported manufacturing process, CaCO 3 powders were dissolved in the aqueous slurry pool tub.…”

“…The Al film is devoted to enhance folding endurance, toughness, and reducing heat radiation. FGC imparts toughness and protection against fire, stresses and alkaline environments [16,21]. Fig.…”

“…Some studies on concrete wall systems [6], wooden door systems [13], terrace constructions [14], and flat roof constructions [15], insulated with VIPs in some European countries, have been reported in literature. Likewise, the manufacturing process and parameters, and some durability issues related to glass fibre VIPs have been studied by experimental and modelling techniques [12,[16][17][18]. However, to the best of our knowledge, no studies have focused on the procedures for installation method and performance of glass fibre VIP, especially in building structures in China.…”

Fabrication and characterization of low-cost and green vacuum insulation panels with fumed silica/rice husk ash hybrid core material

“…Afterwards, it was pressed into a plat HCM. Afterwards, the plat HCM was dried at 120°C for 90 min and then vacuumed and sealed in an envelope using a vacuum machine (see details in our previous published research [28]). Following the same procedures, the 6 groups of VIP samples with dimensions of 290 mm × 290 mm were fabricated.…”

“…7, λ tot-v of the proposed FS/RHA HCM-VIPs under air pressures from 100 Pa to 100,000 Pa was in between that of GF-VIPs and that of opacified FS-VIPs. Table 5 shows the comparison of physical properties of various VIP core materials [12,28,29,38,41,[47][48][49][50][51]. A physical parameter P 1/2,g was used to evaluate λ tot-v stability of the as-prepared VIPs.…”
