2. Application
The rubber thermal shock climatic chamber, indispensable in materials industry such as metal, plastic, rubber, electronics etc, is applicable to test temperature endurance of material structure and composite materials under a rapid shift from extremely high temperature to a extremely low temperature or reverse, so as to find in shortest time the chemical changes or physical damages caused by thermal expansion and contraction.
3. Below are differences between 3-zone and 2-zone thermal shock chamber:
3-zone thermal shock chamber:
three chamber in total: test space, high temp. chamber and low temp. chamber;
Advantage: slight limitation for test sample’s weight, the test sample keep still, this can reduce the impact to samples by moving it, can be used for on-load testing.
Compared with 2-zone type, relatively low failure rate, low cost.
2-zone thermal shock chamber:
Only two chambers: high temp. Chamber and low temp. chamber
Advantage: short conversion time, smaller space needed
Disadvantage: test sample moving. test samples’ size is limited by the basket size
