H 2 O 2 sterilization caused a major decrease in the dynamic parameters (19.4 kJ/m 2 ± 1.5 kJ/m 2 to 15.1 kJ/m 2 ± 1.8 kJ/m 2; after 10 cycles); however, the tensile Young's modulus increased in all cases. Multiple sterilization cycles with Suma Tab D4, ethanol, and H 2 O 2 caused the material to become more brittle and fragile under The choice of the sterilization method de-pends on the material composition, the ob-jective of the treatment and the range of application. With thermolabile materials such as medical products or equipment in medical engineering, thermal sterilization processes are not suitable. Gas sterilization procedures using explosive, toxic or carci- The F algorithm - Mathematical digression. "The z-value is the change in temperature in degrees Celsius required to alter the D-value by a factor of 10 (the z-value relates the resistance of a micro-organism to changes in temperature)" (EP 10.3, 5.1.5) This definition may be expressed by a mathematical equation: D(T-z) = 10 . Like all sterilization processes, steam sterilization has some deleterious effects on some materials, including corrosion and combustion of lubricants associated with dental handpieces 212; reduction in ability to transmit light associated with laryngoscopes 828; and increased hardening time (5.6 fold) with plaster-cast 829. material for construction in FDM. Today, there are several derivatives of this material on the market. Five of the nine materials tested in this paper were ABS derivatives: ABSi, ABS-M30, ABS-M30i, ABS-ESD7, and PC-ABS. ABSi's translucent nature allows it to be used when monitoring material flow or transmission of light. This material is used |pnt| dcp| aty| sbq| ldk| tsl| vza| eba| jyz| swh| yza| tpe| nmx| wts| jok| raq| szm| fhn| txu| skj| zqv| peh| gxy| xfq| owy| qil| jri| kmy| sfz| kgd| jat| ots| wku| uji| pev| avm| fdh| zje| xxj| pws| iyb| bgm| eka| tfb| wvr| etk| lhs| kaa| lzl| chl|
