The Thermo wood process consists of drying, heat treatment and finally cooling/conditioning, and takes up to 72 hours. [4] The Plato process consists of hydrothermolysis, dry curing and conditioning, and can take up to 7 days. The required time depends on wood species, width and initial moisture content. [5]
These processes autoclave the treated wood, subjecting it to pressure and heat, along with nitrogen or water vapour to control drying in a staged treatment process ranging from 24 to 48 hours at temperatures of 180 °C to 230 °C depending on timber species. These processes increase the durability, dimensional stability and hardness of the ...
It has been hypothesized that warm-bloodedness evolved in mammals and birds as a defense against fungal infections. Very few fungi can survive the body temperatures of warm-blooded animals. By comparison, insects, reptiles, and amphibians are plagued by fungal infections.
Hot working or cold working after the annealing process alters the metal structure, so further heat treatments may be used to achieve the properties required. With knowledge of the composition and phase diagram , heat treatment can be used to adjust from harder and more brittle to softer and more ductile.
Heat treatment provides an efficient way to manipulate the properties of the metal by controlling the rate of diffusion and the rate of cooling within the microstructure. Heat treating is often used to alter the mechanical properties of a metallic alloy, manipulating properties such as the hardness, strength, toughness, ductility, and ...
A body is wrapped in a biodegradable shroud and placed in a long metal capsule — surrounded with a mixture of wood chips, mulch and wildflowers. As it decomposes, the body releases nitrogen and ...
Oh, to be a spoiled pet, cherished by an owner whose love knows no bounds and whose wallet has no limits. To never experience a day of work. To never pay rent. To have plenty of entertainment ...
Consolidation can also refer to the treatment of painted wood surfaces. Because of the complicated nature of wood as a material, consolidation of paint on a wooden artifact must be carefully undertaken. As wood expands and contracts with fluctuations in temperature and humidity, damages can occur to paint on the wood's surface.
