4 Νοε 2020 · Acidic aluminum sulfate hydrolysis solutions can be used to catalyze the thermal degradation of wood in a low-temperature environment. Thermally stable hydrogenated hydroxides encapsulate and fill the wood, which increases its thermal stability and mechanical properties.
7 Δεκ 2015 · Alum, or potassium aluminum sulfate, is one of the most useful chemicals during the age of alchemy in 13-18th century. Based on chemical properties, ions of aluminum, antimony, chromium, zirconium, and titanium, as well as boron, are very useful for crosslinking carbohydrates groups in wood fibers. http://www.ashland.
1 Απρ 2022 · In this study, wood samples exhibiting ultraviolet (UV) resistance were successfully fabricated by joint aluminum sulfate (Al2 (SO4)3) impregnation and thermal modification, and the samples...
Acidic aluminum sulfate hydrolysis solutions can be used to catalyze the thermal degradation of wood in a mild temperature environment, and thus reduce the temperature required for heat treatment ...
1 Μαρ 2009 · Here we investigated the retention, fixation, and fungal resistance of Scots pine and beech wood treated with plant extracts and a combination of boric acid, borax, aluminum sulfate, and copper sulfate.
Polydimethylsiloxane (PDMS) and hydrophobic silica nanoparticles (HSNP) were applied to coat wood surfaces to decrease boron release from DOT (disodium octaborate tetrahydrate) treated wood. The … Expand
3 Ιουν 2021 · From the mid-1800s to the late 1960s, conservation by alum salts (KAl(SO4)2·12H2O—potassium aluminium sulphate), using various recipes, was a common method to prevent shrinkage and to strengthen waterlogged archaeological wooden objects. This method was mainly used in Scandinavia.
