Air Permeability Test Machine

Analysis Influence Factors of Fabric And Textile Air Permeability

The air permeability of fabrics is one of the important indicators of fabric performance. The air permeability of wearing fabrics directly affects the thermal insulation and comfort of clothing. The air permeability of some industrial textiles is also closely related to its function. Effect of air permeability of parachute and hose on its performance, etc. At present, there are many studies on the air permeability of textiles in China, but they are often limited to the qualitative analysis between [...]

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 [...]

Electrostatic Discharge (ESD) Protection

Basic overview of ESD   Static electricity is caused by the mutual friction of two different substances, and a high voltage is formed by the accumulation of positive and negative charges in the two objects rubbing against each other. Man-made fibers and plastics are common triboelectric materials, and ESD problems arise when a voltage is generated by friction. For electronic components, electrostatic energy cannot be ignored, it can break down semiconductor components, thereby destroying electronic circuits.   Usually ESD creates EMC problems in [...]

THERMO GRAVIMETRIC ANALYZER(TGA)

THERMO GRAVIMETRIC ANALYZER(TGA) KNOWLEDGE

Thermo gravimetric analysis(TGA) refers to a thermal analysis technique that measures the relationship between the mass of the sample to be tested and the temperature change at a program-controlled temperature, and is used to study the thermal stability and composition of materials. Thermo gravimetric analysis（TGA) is a commonly used detection method in R&D and quality control. It is often used in combination with other analysis methods in actual material analysis to conduct comprehensive thermal analysis and analyze materials comprehensively and accurately. THERMO GRAVIMETRIC ANALYZER(TGA) The [...]

THERMO GRAVIMETRIC ANALYZER(TGA) TEST FAILURE REASONS AND SOLUTIONS

Thermo gravimetric analyzer(TGA)  is a device that measures the relationship between the mass of a sample and temperature or time under a program-controlled temperature and a certain atmosphere. In the early literature related to thermo gravimetric method, a few researchers used to call it “thermo gravimetric analysis method”. In fact, this title is inappropriate, because some samples will have almost the same mass during the experiment. or increase in quality. For example, when many metals are heated to a certain temperature in [...]

Color Fastness Tester

WHAT IS A COLOR FASTNESS TEST?

Color fastness, also known as color fastness, color fastness. Refers to the resistance of the color of textiles to various effects during processing and use.   It refers to the degree of fading of dyed fabrics under the action of external factors (extrusion, friction, washing, rain, exposure, light, seawater immersion, saliva immersion, water stains, sweat stains, etc.) during use or processing.   It grades the fastness based on the discoloration of the sample and the staining of the undyed backing fabric.   Textile color fastness [...]

Differential Scanning Calorimeter，DSC

TIPS WHEN USE THE DIFFERENTIAL SCANNING CALORIMETER(DSC)

In order to ensure the normal use of the differential scanning calorimeter, the sample must not be thermally decomposed within the test temperature range, will not react with metal aluminum, and will not corrode. If the sample to be measured can generate a large amount of gas during the heating process, or can cause an explosion, the instrument cannot be used. Therefore, you should have a general understanding of the nature of the sample before testing. Check whether all connections [...]
