Formation and structure of glass layer in glass lined reactor equipment

Today we will introduce the formation and structure of the glass layer of the glass lined reactor.

The glass lining glaze of the glass lining reactor equipment experienced a series of complex physical and chemical reactions when it became the glass lining layer (porcelain layer for short).

First of all, the glass lining layer includes not only the bottom porcelain layer and the surface porcelain layer, but also the permeable layer between the steel plate and the bottom porcelain layer and the surface porcelain layer.

In order to make the porcelain layer firmly adhere to the steel surface of the glass lined reactor equipment, generally, the glass lined equipment such as the glass lined reactor is divided into five layers, which are called interpenetrating layer, bottom porcelain layer and interpenetrating layer between the bottom porcelain layer and the surface porcelain layer.

Glass lined equipment such as glass lined reaction kettle has the above layered combination phenomenon, which we call “interlayer penetration phenomenon” in the glass lined layer.

Because of this phenomenon, the original composition of the whole glass lining glaze layer has changed greatly, and the physical and chemical properties of the glass lining glaze layer have also changed accordingly. The composition and structure of the outer surface layer of the glass lining layer are also different from that of the glass lining layer, so their physical and chemical properties are also different.

For example, mechanical properties (including surface tension, friction, mechanical strength, adsorption, etc.), chemical properties (including chemical activity, chemical stability) And optical properties (including the reflection intensity of light on the surface of the porcelain layer) are different from those of the glass lined glaze, but they are closely related to the structure of the glass lined layer.

The glass lining layer of the glass lining reactor is the vitreous porcelain layer. Its properties depend on the chemical composition, melting process and firing process of the glass lining glaze. The quality of the porcelain layer determines the service performance of the glass lining equipment. The stability of the glass lining glaze can be controlled or adjusted by detecting the performance of the glaze. The properties of glass lined layer include mechanical properties, thermal properties, optical properties, chemical properties, etc

The above is the knowledge about the glass lining of glass lined reactor equipment. The formation of this layer is very complex. Have you got any help after reading these contents? If so, please pay more attention to us.
