How To Measure The Pet (Polyester) Glass Transition Temperature?

In order to study the quality and characteristics of materials, many industries use differential scanning calorimeter （DSC） to test the glass transition temperature of materials, especially the glass transition temperature of PET (polyester), which is also a relatively common measurement. Differential Scanning Calorimeter  What is glass transition temperature? Glass transition temperature (Tg) refers to the temperature corresponding to the transition from glassy state to high elastic state. Glass transition is an inherent property of amorphous polymer materials and a macroscopic manifestation of [...]

ASTM E96 Automatic Textile Fabric Moisture Permeability Tester

Common Test Methods and Comparison of Fabric Water Vapor Permeability

What is Fabric Water Vapor permeability?         The Water Vapor permeability test of textile fabrics is mainly to test the Water Vapor permeability of fabrics under different temperature and humidity. It is to simulate the ability of textile fabrics to transfer the body to naturally discharge water vapor to the external environment after simulating the sweating state of the human body under different activities. Water Vapor permeability is the quality or efficiency of water vapor transmitted on both sides of the fabric; the [...]

What is Oxidation Induction Time Analyzer?

Oxidation induction time analyzer is a common thermal analysis instrument used to measure the thermal stability and oxidation stability of materials. The OIT test method can evaluate the thermal degradation process of a sample by measuring its oxidation induction time at high temperature, thereby obtaining important information about the stability and durability of the material.   OIT testing typically use differential scanning calorimetry (DSC), a technique that measures the thermal degradation temperature and reaction rate of a sample at elevated temperatures under a predetermined [...]

Vickers Hardness Tester

What Are The Factors That Affect The Vickers Hardness Tester Value?

What are the factors that affect the hardness value of the Vickers hardness tester? This should be analyzed from the test principle and test conditions, specifically the following aspects: 1. Hardness tester: (1) Load mechanism: mainly includes the change of weight weight; the movement condition of the load mechanism; the friction force of the main shaft; the perpendicularity between the main shaft and the worktable; the change of the load lever arm ratio. (2) Indenter: It mainly includes two aspects: the geometric [...]

General Reasons For Failure Of Thermogravimetric Analyzers（TGA) And Their Solutions

Thermogravimetric analyzer （TGA) is a device that measures the relationship between the quality of a sample and temperature or time under a program-controlled temperature and a certain atmosphere. In the early literature related to thermogravimetric method, a few researchers used to call it “thermogravimetric 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 [...]

Universal Testing Machine Testing Error Solution

  Universal testing machine is an important equipment in the research of material mechanics, but there are many kinds of testing machines, such as fatigue testing machine, etc. Different testing machines can meet different measurement needs. But no matter what type of testing machine it is, there will be errors in the measurement, so people will finally determine the precise value after many experiments.   The method of multiple experiments is used to avoid the error rate of the measurement value and [...]
