In the process of taking, the fabric is constantly exposed to the top and pressure of the concentrated load and expands until it is damaged, especially the elbows, knees and other parts of the clothing. This damage is called bursting or bursting.
Because the fabric [...]
Electronic testing machine:
The electronic testing machine is a new generation of dual-space microcomputer controlled electronic testing machine specially designed for universities and research institutes. The design of the main machine and auxiliary equipment of the testing machine draws on the advanced technology of Shimadzu, [...]
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 [...]
A common type of interference is transient pulse interference . The characteristics of this type of interference noise are: large amplitude, short time, and wide frequency spectrum, which are more harmful to equipment. To solve this kind of interference, we need to use some [...]
Test temperature: The temperature of the laboratory for impact testing should generally be within the range of 10~35℃ (that is, the room temperature). For tests with strict requirements, such as the impact test of materials whose toughness is sensitive to temperature changes, the test [...]
Vacuum Sealing Tester adopts a new type of high-precision intelligent detector with modern mechanical design concepts and computer processing technology. The Vacuum Sealing Tester is widely used in seal quality leak detection, packaging integrity testing, micro-leak detection, bag leak detection, and blister packaging. Inspection, [...]
Fabric martindale abrasion wear tester is a kind of instrument used to measure the friction coefficient of fabric surface, which is widely used in textile, clothing, footwear and other industries. In order to ensure the accuracy and service life of the instrument, it is very [...]
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 [...]
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 [...]
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 [...]
