lSunshine 22A gel time tester, conforming to ASTM D3056-85, convenient and quick to obtain the gel time of thermosetting compounds

L Accurately obtaining the gel point of thermosetting compounds is crucial for evaluating the properties of polymer materials such as resin, wax, styrene, monomer, perfusion mixture, melamine, formaldehyde, unsaturated grease, thermosetting food and other polymeric materials

L The viscosity of the compound usually increases rapidly and significantly at the gel point, and the gel point can be used to infer the storage time of the substance (by describing the gel time -1/t (temperature) curve)

L The gel time can be simply obtained at two or more temperature rise points, and can be inferred according to the surrounding environment. The gel point should be located in a straight line with an inclined descent.

L The gel tester provides an accurate and reliable method for measuring the gel point of compounds (or other materials). Generally, the gel point of a substance is defined as the time point at which the substance reaches the initial solidification state under constant temperature.

L It is an ideal choice for production, quality management and research. It is simple to operate and can obtain gel points. The results are reproducible (within ± 1% error). When reaching the gel point, it automatically shuts down, and eliminates error testing. When reaching the gel point, it generates an audible and visual alarm signal and automatically indicates the closing time of Z in seconds

Typical steps for measuring gel points:

Add the test sample into the test tube and immerse it in a constant temperature dish

Insert the stirring glass rod into the test tube

The glass rod is connected to a torsion metal wire, which is driven by a synchronous motor with a rotation rate of 1 revolution per minute

L When timing starts, the gel tester monitors the test process until the gel point is reached

L When reaching the gel point, the gel time will be displayed and the audible and visual alarm signal will be sent at the same time

Digital temperature controller provides safe and automatic constant temperature control for gel process, which is an ideal choice for constant temperature immersion in gel process. As long as the temperature control point (Z can reach up to 315 degrees) is simply set on the front panel, the controller will control the temperature within ± 0.2 degrees of the set point after constant temperature.
