Dry heat shrinkage tester


The dry heat shrinkage tester is a crucial instrument for testing the dimensional changes of materials under high-temperature conditions, and is of great importance in ensuring product quality and stability.

Application

It is used to test the dry heat shrinkage performance of tire cord, yarn, polyester, cotton and other materials under certain temperature conditions.

Standards

GB/T9101-5.4-2017: Polyamide 66 dipped tyre cord fabric

GB/T9102-6.8-2016: Nylon 6 dipped tyre cord fabric

GB/T19390-7.4.1-2023: Dipped polyester cord fabric for tyres

ASTM D4974-2002: Standard Test Method for Rubber Thread - Determination of Dry Heat Shrinkage

Features

One machine for dual use, can separately test shrinkage rate and shrinkage force;

The system uses touch screen to carry out man-machine dialogue and input operation directly on the interface;

The temperature module is directly used to collect temperature, the thermocouple is built-in, PID control output heater, and heating temperature and heating speed can be set on the touch screen;

Through the LCD display, can directly display the current test data, while providing data storage function, can query multiple groups of test results, and can calculate the test results;

Equipped with a micro printer to print two values of shrinkage and shrinkage force respectively.
