Glass high-temperature viscometer

1、 Product Introduction:

The glass high-temperature viscometer can not only measure viscosity values, but also determine the softening point of glass according to the ASTM 1351M standard method. The softening point of glass is a widely used production control parameter, and changes in the softening point temperature indicate changes in the chemical composition of glass. If the softening point temperature of glass cannot be obtained through glass fibers, it can be obtained quickly and simply through a flat plate viscometer.

2、 Testing principle:

The cylindrical glass sample is placed in a high-temperature furnace, and a sample cup is placed with a Theta rotor connected to a Brookfield viscometer. After heating to the test temperature, the rotational viscometer is started. The slurry glass sample will rotate under the drive of the viscometer rotor, and the DV3T detector will detect its resistance and rotation rate to calculate the viscosity value of the glass.
