Information

The physical performance of tranter gasketed plate heat exchanger gaskets at high temperatures is an important indicator for judging the quality of gaskets. The physical properties of tranter gasketed plate heat exchanger gaskets mainly depend on the formula-mixing and vulcanization process. Generally, the pressure of vulcanization-molding should not be less than 9.8MPa, the temperature is 160~185C, and the time is 3~15min, depending on the type of rubber.

The physical properties of tranter gasketed plate heat exchanger gaskets will deteriorate with the use of time and temperature. Generally, the average life span of continuous use is about two years at the highest recommended temperature of rubber gaskets. Above the maximum temperature of 10°C, the average life expectancy is about half shortened. However, short-term over-temperature has little effect. Gaskets with good physical properties at room temperature may become poor under high temperature and continuous use. For this reason, it is very important to ensure the physical properties of the tranter gasketed plate heat exchanger gasket at high temperatures.

The compression set rate is an important basis for measuring the elastic recovery ability of the tranter gasketed plate heat exchanger gasket material and determining the use temperature limit. Under the allowable use temperature, the smaller the value, the better the elastic recovery performance, and the better the sealing performance and average life of the gasket.

The tear strength reflects the sensitivity of the tranter gasketed plate heat exchanger gasket to the gap and the ability to resist cracking under a certain pressure. The gaskets with low tear strength are easy to crack at the sharp corners when the plates are loaded and removed under pressure. This is especially important for non-adhesive gaskets. After the rubber is aged, the degree of change in its physical properties has a significant impact on the temperature resistance and service life of the gasket.

Hardness is one of the indicators to measure the degree of vulcanization of rubber products, and it has a certain impact on the temperature resistance of tranter gasketed plate heat exchanger gaskets. The hardness is higher, and the service temperature of the tranter gasketed plate heat exchanger gasket is also higher.
