Differential Scanning Calorimeter,DSC

What Can a Differential Scanning Calorimeter（DSC) Measure?

Differential scanning calorimeter is also referred to as DSC. DSC is to make the sample under the control of a certain temperature program (rise/decrease/constant temperature), and observe the change process of the heat flow power difference between the sample end and the reference end with temperature or time. Obtain relevant thermal effect information such as the endothermic, exothermic and specific heat changes of the sample during the temperature program, and calculate the endothermic and exothermic heat (enthalpy) and characteristic [...]

Fabric Air Permeability Testing Principle

Important factor that affects the comfort of the fabric is the air permeability of the fabric. Sportswear and windproof and coldproof clothing have higher requirements on the air permeability of fabrics. Some industrial textiles, such as aircraft parachutes and filter cloths, have special requirements for the air permeability of fabrics. The air permeability of the fabric is determined by the number and size of the warp and weft yarns and the fiber gap in the fabric, and is also [...]

Application and Characteristics of Synchronous Thermal Analyzer

During the heating process of the synchronous thermal analyzer, if the measured substance sublimates, vaporizes, decomposes or loses crystal water, the quality of the measured substance will change. At this point, the thermogravimetric curve is not straight, but decreasing. By analyzing the thermogravimetric curve, you can know at what temperature the measured substance has changed and calculate how much weight loss is lost. Below we introduce the application and characteristics of the synchronous thermal analyzer. The thermogravimetric curve shows that [...]

Surge Simulator For Surge Immunity Testing Method EMC Test

The Surge Simulator is an advanced high voltage source and measurement unit consisting of programmable pulse trains and advanced pattern analysis software. The instrument takes normal 115 or 220V AC power and converts it to the higher voltage required for surge testing. The higher voltage is rectified to a DC voltage, which charges the large discharge capacitor. The order of the surge tester tests is important, after the resistor is heated, the resistance will decrease. After the resistance is reduced, [...]

Melt Flow Index Tester(MFR)

Melt Flow Index Tester(MFR) Working Principle

Melt Flow Index Tester (MFR) is to use a high temperature heating furnace to make the measured object reach a molten state under the specified temperature conditions. The test object in this molten state is subjected to the extrusion test through a small hole of a certain diameter under the specified weight load. In the research of plastic production in industrial enterprises and scientific research units, “melt (mass) flow rate” is often used to represent the physical properties such as [...]

EN/IEC61000-4-2,ISO10605 EMC ESD Simulator

  Discharge Method Of Electrostatic Discharge Simulator ESD GUN and ESD Generator

Electrostatic discharge simulator, also called electrostatic discharge generator or ESD simulator. The electrical model of the ESD discharge source is very simple, but it is a very complicated task to produce an electrostatic simulator that can not only reflect the main characteristics of the real ESD process, but also have high discharge repeatability. General electrostatic discharge simulators use lumped parameter circuits to achieve their functions. However, ESD itself is a transient process involving high frequency components over 1 GHz. [...]

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 [...]
