Because of the relatively low temperature used, AAC blocks are not considered to be a fired brick but a lightweight concrete masonry unit. After the autoclaving process, the material is stored and shipped to construction sites for use. Depending on its density, up to 80% of the volume of an AAC block is air.
The autoclave was invented by Charles Chamberland in 1879, [3] although a precursor known as the steam digester was created by Denis Papin in 1679. [4] The name comes from Greek auto-, ultimately meaning self, and Latin clavis meaning key, thus a self-locking device. [5] Video demonstrating how autoclaves work
Autoclave tape is an adhesive tape used in autoclaving (heating under high pressure with steam to sterilise) to indicate whether a specific temperature has been reached. [1] Autoclave tape works by changing color after exposure to temperatures commonly used in sterilization processes, typically 121°C in a steam autoclave.
The crystallization vessels used are autoclaves. These are usually thick-walled steel cylinders with a hermetic seal which must withstand high temperatures and pressures for prolonged periods of time. Furthermore, the autoclave material must be inert with respect to the solvent. The closure is the most important element of the autoclave.
The upper mould is installed, and the vacuum is applied to the mould cavity. The assembly is placed into an autoclave. This process is generally performed at both elevated pressure and elevated temperature. The use of elevated pressure facilitates a high fibre volume fraction and low void content for maximum structural efficiency. [1] [2]
Italian-made Calzuro clogs take cleanliness to a new level in their classic clog style, which can not only be machine washed and bleached, it can be sterilized in an autoclave at temperatures up ...
Out of autoclave (OOA) is a process that achieves the same quality as an autoclave but through a different process. [1] OOA curing achieves the desired fiber content and elimination of voids by placing the layup within a closed mold and applying vacuum, pressure, and heat by means other than an autoclave.
Polymerization in an autoclave is a technique which allows laminates with the best mechanical properties to be obtained, but it is the most expensive and permits only the use of open moulds. The advantage is due to the fact that the pressure helps to bond the composite layers and to eject air inclusions and volatile products, increasing the ...
