Combinations of expanded glass Svenska Aerogel AB, Gävle. 523 gillar · 46 pratar om detta · 2 har varit här. Svenska Aerogel tillverkar en unik produkt Quartzene® - Next Generation Aerogel. Quartzene används för att förbättra Product Description. Aspen Aerogels’ Spaceloft ® is a flexible aerogel composite blanket designed for insulating buildings and apparel. With a thermal conductivity of 14 mW m-1 K-1, Spaceloft is approximately two and half times better insulating than Styrofoam ®. 2 aerogel composites with different factions (from 0 to 10 %) of mullite fibers are in the range of 0.225–0.419 g cm-3 and corresponding porosities are in the range of 89–94 %.

Chitosan was investigated as a MFC/NFC aerogel reinforcing agent in this paper. The reinforced aerogel showed slightly tighter structure and very good water stability and mechanical strength. FTIR disclosed the chemical bonds formed between chitosan and cellulose. Aerogel blankets are composites of silica aerogel particles dispersed in a reinforcing fiber matrix that turns the brittle aerogel into durable and flexible insulating materials. In this study, silica aerogel was loaded on glass wool with different concentrations (0–18.6%) and morphological and thermal characteristics of the aerogel blankets were studied. The porosity of the aerogel (P) was calculated by Eq. 1, where ρ c was the density of bulk cellulose (1.528 g/cm 3).

2015-03-01 Phase change materials (PCMs) can be thermally enhanced by reduced graphene oxide (rGO)/expanded graphite (EG) aerogel with anisotropic microstructure. An rGO/EG aerogel with anisotropic microstructure was prepared by directionally freezing aqueous suspensions of graphene oxide (GO) and EG, followed by a freeze-drying process and thermal reduction at 250 °C.

When the laboratory moments were completed the only thing remaining was to analyse the test results and to compile these results to give Svenska Aerogel AB a better overview of their different variants of Quartzene®. 2 Background 2.1 Aerogels Needleless electrospinning and electrospraying of aerogel particles in comparatively lower electric voltage (9 kV) have been demonstrated in the paper. Aerogel particles were dispersed in polymer solution and then needlelessly electrospun/sprayed by creating high electric charge at the syringe tip using a curved wire.

Após dois anos de estudo, desenvolvimento e testes de novas formulações que permitissem resolver o problema da libertação de partículas e pó sem por em causa as propriedades únicas que fazem dos aerogéis excelentes isolantes térmicos (leveza, baixa condutividade térmica e versatilidade), o primeiro aerogel “limpo” produzido pelos investigadores da FCTUC e Active Aerogels está To visualize the microstructure of the SiBCO aerogel we employed SEM, and the SEM images of composites with different contents of NH 3 •H 2 O are shown in Figure 6. When the amount of NH 3 •H 2 O is small ( Figure 6 a), the gel speed is relatively slow, and small particles formed at the beginning of gel tend to bond evenly, forming a more uniform porous structure. The typical aerogel structure of KNA films endows them with excellent thermal insulation performance, which exhibited a thermal conductivity of 0.036 W/m·K (density of 29.35 mg/cm 3) at room temperature. This value is comparable to that of cellular aerogel (0.0304 W/m·K with a density of 9.6 mg/cm 3) and other thermal insulators.
