Thermogravimetric Curve(TG Curve) Affect Factors Analysis
1) The influence of the instrument ① Influence of buoyancy a) When the thermal balance is in the hot zone, the weight of its components to displace the air during the heating process is decreasing, that is, the buoyancy is decreasing, that is, the performance of the sample increases. b) The atmosphere around the thermal balance sample becomes lighter when heated, and will rise upward, forming an upward hot air flow, which acts on the thermal balance and is equivalent to weight [...]
