belts in car engines

However, flat belts also have disadvantages. Their efficiency can decrease significantly under heavy loads, as they rely on friction to transmit power. This limitation can lead to slippage, especially when the load exceeds the belt's capacity. Consequently, flat belts are less suitable for high-torque applications where a consistent grip is essential. Furthermore, the alignment of the pulleys must be precise; any misalignment could cause significant wear or failure.

  • Besonderheiten: Wässrige HPMC-Gele neigen dazu, bei der Erwärmung bei einer bestimmten Temperatur sehr schnell ihre Viskosität zu erhöhen. Diese Temperatur wird häufig als Gelpunkt bezeichnet, was in diesem Fall jedoch nicht völlig korrekt ist. Dieser Verfestigungsprozess ist reversibel, das heißt, sobald die Temperatur genügend gefallen ist, wird auch das Gel wieder flüssiger. Diesen Effekt macht man sich z. B. in der Lebensmitteltechnologie zunutze: Bratlingen wird HPMC zugesetzt, damit sie beim Braten (hohe Temperatur) fest, beim Verzehr (niedrigere Temperatur) jedoch wieder zart sind.
