Embodiment 26 (oxidation behavior of 304 stainless steels in the fire field environment of kerosene combustion adjuvant)
Use kerosene to burn as fuel simulation combustion adjuvant, uses 304 stainless steels common in daily life as simulation Metal oxide material uses the device analysis sample such as scanning electron microscope, energy disperse spectroscopy, atomic force microscope and X-ray diffractometer Product surface oxidation state;Because kerosene boiling point is 175-325 DEG C high, and degree of volatility is far smaller than ethyl alcohol and gasoline, so heating Device uses coil heats, and heating temperature is set as 300 DEG C, is first turned on all valves of equipment, allows its kerosene gas equipment Interior air discharge, the valve after turning off heat preservation air collector, air collector 2 to be kept the temperature store a certain amount of fuel gas, reach Make fuel spray volume keep stablizing by second heating apparatus 3 and pressure maintaining valve after certain air pressure, then lights, obtain stablizing combustion The kerosene flame of burning.304 stainless steel samples are the sheet of 2*10*20mm, and suspension sample, sample are hung for convenience for top punching Above at the flame-thrower nozzle vertical edge at 10cm, be not directly contacted with flame, oxidization time be respectively 0.5min, 1min, 2min, 3min, 4min, 5min, 10min, 20min, 30min carry out mechanical polishing processing to 304 stainless steels.Kerosene is mainly carbon original The high-boiling hydrocarbon mixture of subnumber C11-C17.Main component is saturated hydrocarbons, also contains unsaturated hydrocarbons and aromatic hydrocarbon.Because of product Kind is different to contain alkane 28-48%, aromatic hydrocarbons 20-50% or 8%~15%, unsaturated hydrocarbons 1-6%, cyclic hydrocarbon 17-44%.Carbon atom Number is 11-16.In addition, there are also a small amount of impurity, such as sulfide (mercaptan), colloid.Wherein sulfur content 0.04%~0.10%. Without benzene, alkadienes and cracked distillate.It therefore is mostly CO in kerosene combustion product2, H2O(g), CO etc., also containing a small amount of N Oxide, the oxide of S, these gases are all oxidizing gas, this more aggravates compared to the oxidation in ethanol combustion environment It is strong, it is not easy to be oxidized relative to 304 stainless steels in normal circumstances, but can ratio in the environment of oxidizing atmosphere It is easier to aoxidize in conventional environment.Kerosene burning generation corrosion products can also be to 304 stainless steels to a certain extent The protective oxide layer that sample generates generates corrosiveness, while the high heat for generation of burning also exacerbates to a certain extent The oxidation of 304 stainless steels.Meanwhile since the imperfect combustion of kerosene can deposit carbon in sample surfaces, and deposit the content of carbon Related with the carbochain length of combustible, these features are very different with aoxidizing in normal air, could act as judging Whether kerosene combustion adjuvant existing for reference point is had in the scene of a fire.
(304 stainless steels are in the fire field environment existing for kerosene combustion adjuvant and combustible paper, cotton, plastics for embodiment 27 Oxidation behavior)
Use kerosene to burn as fuel simulation combustion adjuvant, uses 304 stainless steels common in daily life as simulation Metal oxide material uses the device analysis sample such as scanning electron microscope, energy disperse spectroscopy, atomic force microscope and X-ray diffractometer Product surface oxidation state;Because 175-325 DEG C of kerosene boils up till, and degree of volatility is far smaller than ethyl alcohol and gasoline, so plus Thermal uses coil heats, and heating temperature is set as 300 DEG C, is first turned on all valves of equipment, its kerosene gas handle is allowed to set Standby interior air is discharged, and the valve after turning off heat preservation air collector, air collector 2 to be kept the temperature stores a certain amount of fuel gas, reaches Make fuel spray volume keep stablizing by second heating apparatus 3 and pressure maintaining valve after to certain air pressure, then lights, stablized The kerosene flame of burning.304 stainless steel samples are the sheet of 2*10*20mm, and suspension sample, sample are outstanding for convenience for top punching Hang at flame-thrower nozzle vertical edge at the 10cm of top, be not directly contacted with flame, oxidization time be respectively 0.5min, 1min, 2min, 3min, 4min, 5min, 10min, 20min, 30min, while being placed in the combustible addition accessory around burner Paper, cotton, plastics powder, sprayed, be mixed and burned with certain rate while burning.Paper, cotton, plastics are all families Common combustible in life if these combustibles once combustion adjuvant ignites, the intensity of a fire certainly will will increase, therefore is simulated have can The oxidation behavior of metal material is of great significance in the environment of combustion things and combustion adjuvant exist simultaneously.Because paper, cotton, plastics are Polymer substance, so combustion product is mostly CO, CO2, H2O(g)Deng, except that because cotton is handled by colouring, Also containing the oxide of S in combustion product, the oxide etc. of N, and because the C chain length molecular weight of plastics is big, while also containing very More S, N, the functional group of Cl is so product is more complicated in addition to CO, CO2, H2O(g)Outside equal conventional products, there are also S, the oxide of N, Containing benzene ring compound, HCl, phenols, the harmful substances such as aldehydes, these products are all oxidisability products, this more exacerbates kerosene The content for the oxide that burning generates, this can have more further facilitation, while combustible to the oxidation of 304 stainless steels The corrosion products generated of burning also can have corrosion function to the compact oxidation layer that 304 stainless steels itself are formed, and accelerate 304 not The corrosion of rust steel.304 stainless steels in the same time how much can be speculated according to the content of oxidizing substance in oxidation product The state of oxidation, protective oxide layer extent of the destruction etc., while sample surfaces can deposit carbon, as the increase carbon of flammable carbochain is heavy Product also will increase.These oxidation features could act as judging whether have kerosene combustion adjuvant and the existing reference of combustible in the scene of a fire Point.
