silicone pot lidBright and colorful is one of the popular kitchen uses among consumers, so is silicone pot lid safe? Will it burst after prolonged use?

Below, let me briefly introduce the characteristics of steel silicon bonded glass covers:

Tempered glass/tempered glass is classified as safety glass. Tempered glass package is actually a type of prestressed glass. In order to improve the strength of glass, chemical or physical methods are generally used to form compressive stress on the surface of the glass. When the glass receives external force, it first offsets the surface stress, thereby improving its load-bearing capacity and enhancing its resistance to wind pressure, heat and cold, impact, etc. The characteristics of tempered glass covers are strong safety. When the glass is damaged by external forces, the fragments will form blunt angled small particles resembling honeycomb shapes, which are not easy to cause severe damage to the human body. In addition, it has a high-strength function, with tempered glass of the same thickness having an impact strength 3-5 times that of regular glass and a bending strength 3-5 times that of regular glass. In terms of thermal stability, tempered glass has outstanding thermal stability, with an acceptable temperature difference of three times that of ordinary glass and a temperature difference variation of 300 ℃. Therefore, in the pot accessories of kitchen supplies, tempered glass is often used to make silicone pot covers, silicone pot covers, etc. The phenomenon of spontaneous explosion of tempered glass without direct mechanical external force is called self explosion of tempered glass. Self explosion is one of the unique properties of tempered glass, and there are many reasons for the occurrence of self explosion of tempered glass covers. However, it can be briefly summarized into the following two types:

1. The impact of glass quality defects: The parts of glass containing stones and impurities are the weak points and stress concentration areas of tempered glass.

Especially if the stone is located in the tensile stress zone of tempered glass, it is an important factor leading to explosion.

Stones exist in glass and have a different coefficient of expansion than the vitreous body. The stress in the crack area around the stone after glass tempering will increase exponentially.

When the expansion coefficient of the stone is smaller than that of glass, the tangential stress around the stone is in tension. The crack propagation that accompanies the stone is highly prone to occur.

2. Due to improper heating process or operation, the surface of the glass may have defects such as scratches, explosion edges, and deep edges, which can easily lead to stress concentration or self explosion of tempered glass.

But please feel free to use the silicone glass cover, no matter what the situation is, it will not burst at all and is safer!
