►Software introduction:
- Oxidation period test of PE, PPR and other pipes:
The oxidation induction time (OIT) was measured by DSC
(differential scanning calorimeter). The sample is usually heated
to the specified temperature and constant temperature under
nitrogen atmosphere, and then switched to oxygen atmosphere. After
a period of time, the material begins to oxidize and release heat.
The released heat is detected by the sensor, and the induced
oxidation time (OIT) is obtained through software analysis. The
length of the oxidation induction time is a parameter of the
oxidation decomposition resistance of the reaction material, which
is still very meaningful. Usually, the parameter must be detected
for buried plastic pipes.
- Glass transition test of resin and other materials:
For amorphous polymers, when the polymer changes from a high
elastic state to a glass state through cooling, or from a glass
state to a high elastic state through heating, the process is
called the glass transition, and the temperature at which the glass
transition occurs is called the glass transition temperature. For
crystalline polymers, the glass transition refers to the transition
of the amorphous part from the high elastic state to the glass
state (or the glass state to the high elastic state). Therefore,
glass transition is a common phenomenon in polymers. However, the
glass transition phenomenon is not limited to polymers, and some
small molecular compounds also have glass transition.
- Material melting point and enthalpy test (thermal stability test)
The melting point is the temperature at which a solid changes its
state of matter from solid to liquid, and the peaks of
multi-component mixtures are also multi-peaks; The measurement of
enthalpy value is also applicable to the measurement and analysis
of crystallinity.
- Curing test of glue and other materials
Refers to the process of material from low molecular weight to high
molecular weight, and the strength of solidified sample will be
higher;
