The Difference Between a Differential Scanning Calorimeter DSC And a Differential Thermal Analyzer DTA

Differential Thermal Analysis (DTA) is an important thermal analysis method, which refers to a testing technique that measures the relationship between the temperature difference between a substance and a reference substance and the temperature or time under program temperature control. This method is widely used to determine the characteristic temperature of a substance and the amount of heat absorbed or released during thermal reactions, including physical or chemical reactions such as phase change, decomposition, compounding, solidification, dehydration, and evaporation [...]

Textile Fabric Rotawash Color Fastness Tester

Fabric And Textile Specimens Making For Color Fastness Washing Testing

  The color fastness test is to simulate the color fastness of textiles under different environments or conditions. There are many kinds of color fastness test items, such as soaping resistance, water stain, sweat stain, light fastness, etc. Different test items have certain differences in sampling. Even if it is the same test method, the sampling methods of different personnel are affected by factors such as habits and subjective judgments, which will cause certain differences in test results.        We roughly divide [...]

The Influence Of Atmosphere On The Analysis Of Thermo Gravimetric Analyzer

Thermo gravimetric Analysis measures the relationship between sample weight and weight change rate with temperature in a program controlled temperature and an atmosphere. Generally used to determine the decomposition of the sample and the stability of the material. It can also be used to determine the weight change of the sample in the process of decomposition, oxidation, dehydration, and adsorption.　　The basic principle of the thermo gravimetric analyzer is that the balance displacement caused by the sample weight change is [...]

Application and Experienceof Differential Scanning Calorimetry DSC In Polymer Material Research

1 The working principle of differential scanning calorimetry (DSC)Differential Scanning Calorimetry (DSC) is a thermal analysis method developed after the 1860s. It is a method of measuring the relationship between the power difference input to the sample and the reference material and the temperature under the control of the program temperature. Kind of technology [1,2]. The accuracy of this change in measurement difference is higher than the measurement of the absolute value of heat flow or power [3]. Its [...]

What is MFI mean in plastic testing area

MFI is abbreviated as melt index, also called melt flow rate, It is a numerical value indicating the fluidity of plastic materials during processing. It is formulated by the American Standards Association for Measurement and Testing (ASTM) according to the method used by DuPont to identify the characteristics of plastics. The test method is: First let the plastic pellets melt into a plastic fluid within a certain time (10 minutes), at a certain temperature and pressure (various material standards are [...]
