Nettet1. mai 1998 · The limit oxygen index of PP and fire retarded PP are listed in Table 3. It can be seen that the LOI value of pure PP is very low (17.8). It means that PP is flammable. By adding APP in pure PP, the LOI value of PA23 is 34.5 and shows good protection for PP. NettetThe peroxide value is defined as the amount of peroxide oxygen per 1 kilogram of fat or oil. Traditionally this was expressed in units of milliequivalents, although in SI units the appropriate option would be in millimoles per kilogram (N.B. 1 milliequivalents = 0.5 millimole; because 1 mEq of O2 =1 mmol/2=0.5 mmol of O2, where 2 is valence).
NettetThe composite material for molding a fiber-reinforced plastic is characterized by containing: a reinforced fiber component comprising at least one type of inorganic fiber selected from a glass fiber and a carbon fiber; and a matrix resin component comprising thermoplastic super-engineered plastic fibers having a limiting oxygen index of not less than 25, a … Nettet27. feb. 2024 · 1 INTRODUCTION. The Gill Oxygen Limitation Theory (GOLT) posits that in aquatic, water-breathing ectotherms, oxygen uptake at the gills limits the aerobic metabolic rate and ultimately, growth and other processes that rely on the energy produced by aerobic metabolism (Pauly, 1981, 2010, 2024).The basis of this theory is that the …
