Organic Thermal Insulation Based on Wheat Straw

Development of Straw Insulation Board : Fabrication Methods , Structure , Thermal Performance

Insulation board is being fabricated and tested for use in developing countries. It is made at a low density, in the area of 5 to 10 pounds per cubic foot (80 to 160 kilograms per cubic meter), and has good thermal properties for an air based insulation, meaning R3 to R4 per inch (Btuin/hr-ft2-oF)-, or a conductivity of .048 to .036 W/m-K. The initial effort is to produce a straw insulation boa...

The effect of wheat straw bleaching on some mechanical properties of wheat straw/LDPE biocomposites

Using biocomposites containing wheat straw (WS) and synthetic polymers like polyethylene (PE) has gained tremendous popularity, but its application in the packaging industry is not substantial. Due to the prevalence of raw WS color which manifests itself in the WS/LDPE biocomposite, the present investigation is dedicated to fabricate a bleached WS/LDPE composite. Thus, raw WS and the pulp of WS...

Chemical Treatment of Wheat Straw

Biodegradable Nanocomposites from Wheat Straw

We investigate the mechanical and thermal properties of cellulose nanofiber reinforced starch based thermoplastic composites. Cellulose nanofibers were isolated from wheat straw by a chemi-mechanical technique. Their morphology, physicochemical and thermal properties were investigated to examine potential applications as reinforcement fibers in biocomposites. Transmission electron microscopy re...

Thermal degradation and fire behaviour of thermal insulation materials based on food crop by-products

Natural thermal insulation materials developed from renewable crop by-products and natural binders are analysed in terms of their thermal degradation and fire behaviour. A pyrolysis combustion flow calorimetre (PCFC) is used to characterise some kinds of crop by-products, including rice husk, corn pith and barley straw. This technique is complemented with a TG analysis. Six thermal insulation m...
