Revulsive to oxidation influence checks temperature of sample weight, constant temperature the experiment considers to report
Oxidation is revulsive time (isothermal OIT) , it is to show stability changes material to be able to bear or endure a kind of when oxidation decomposes opposite magnanimity, in often press, below oxygen or air atmosphere and formulary temperature, through measuring hot law to determine data appears the time with radiative oxidation.
We are in experimental process, discover sample weight, configuration, ply, to experimental result as good as Chang Ying rings; Constant temperature, bigger to experimental result influence, particular test operates as follows:
Scanning shows to measure hot appearance to accord with GB in difference " GB/T 19466.6-2009 plastic difference shows scanning to measure Refadi 6 parts: Oxidation is revulsive time and oxidation are revulsive of temperature determine " below the condition, to shorten experimental time, plan two duplex operation difference shows scanning to measure hot appearance DSC-BM2 (odd second check two sample at the same time, give data at the same time) ; Equipment falls in same moving pattern plate, full automatic move, identify oxidation automatically to be calculated revulsive end mark, automatically, remove artificial interference;
Graph 1: DSC-BM2 difference shows scanning to measure hot appearance
Graph 2: DSC-BM2 difference shows scanning to measure hot appearance and body of heater
Oxygen a bottle: First-rate product of 99.5% industry oxygen (particularly dry) ; Nitrogen a bottle: 99.99% purity nitrogen (particularly dry) ; Entrance electron balance (1/100000 gram) ; Common and plastic grain: Cut becomes 30mg (whole) , 15mg (1/2) , 5mg (1/6) a certain number of.
Graph 4: The plastic grain that this second experiment needs
We install 3 different temperature, 210 ℃ , 220 ℃ , 230 ℃ , the test expresses place to show as follows as a result:
Express one: Below weight of different temperature, different sample, oxidation is revulsive experimental result
By on the watch is shown, oxidation is revulsive time suffers temperature the impact is bigger, weight does not have an influence almost; Temperature, every are elevatory 10 ℃ , oxidation is revulsive time shortens for original 40%-50% .
Graph 5: Below 210 ℃ condition, 30mg sample oxidation is revulsive time
Graph 6: Below 210 ℃ condition, 15mg sample oxidation is revulsive time
Graph 7: Below 210 ℃ condition, 5mg sample oxidation is revulsive time
Graph 8: Below 220 ℃ condition, 30mg sample oxidation is revulsive time
Graph 9: Below 220 ℃ condition, 15mg sample oxidation is revulsive time
Graph 10: Below 220 ℃ condition, 5mg sample oxidation is revulsive time
Graph 11: Below 230 ℃ condition, 30mg sample oxidation is revulsive time
Graph 12: Below 230 ℃ condition, 15mg sample oxidation is revulsive time
Graph 13: Below 230 ℃ condition, 5mg sample oxidation is revulsive time
Accordingly, if you need to do data to contrast with other unit, want to had been communicated ahead of schedule, how much is comparative temperature, oxidation is revulsive the experiment is longer, otherwise, may appear greatly extremely data is opposite on, cause needless misunderstanding.
If to above paragraphs data and viewpoint He Yi is discussed, welcome to be contacted with us, have a test contrast and discuss, we are expecting the make a comment or criticism of each researcher.
