How thick is the glass in the enamel reactor

　　Glass lined reactor is a corrosion-resistant equipment widely used in industries such as chemical,pharmaceutical,and food.It forms a composite structure that combines metal strength and glass corrosion resistance by high-temperature sintering a layer of glass glaze on the surface of a metal substrate.The thickness of the glass layer directly affects the corrosion resistance,impact resistance,heat transfer efficiency,and service life of the equipment.So,how thick is the glass layer in the enamel reactor?What are the effects of different thicknesses on equipment performance?
　　1.Standard thickness of enamel glass layer
　　According to international and domestic industry standards,the glass layer thickness of enamel reactors is usually divided into the following categories:
　　(1)Bottom glaze layer
　　Thickness range:0.1-0.3 mm
　　Function:Enhance the bonding force between the metal substrate and the glass layer to prevent peeling.
　　(2)Surface glaze layer
　　Thickness range:0.8~1.5 mm(total thickness is usually controlled within 1.0~2.0 mm)
　　Function:Provide primary corrosion resistance and wear resistance.
　　Common industry standards:
　　Ordinary industrial grade:total thickness 1.0-1.5mm
　　High corrosion resistance level:total thickness 1.5-2.0 mm

　　Special applications:may be thicker to ensure higher safety and chemical resistance.

　　How to detect the thickness of the glass layer?
　　To ensure the quality of the glass lined reactor,the following methods are usually used to detect the thickness of the glass layer:
　　(1)Ultrasonic thickness gauge
　　Non destructive testing of glass lined reactors,suitable for finished equipment,with an accuracy of up to±0.1 mm.
　　(2)Metallographic microscope
　　After cutting the sample,observe the cross-section and measure the thickness.
　　Mainly used for laboratory or production quality control.
　　(3)Electric spark detection

　　Check whether the glass layer is uniform and free of defects.

　　2.Conclusion:What is the thickness of the enamel layer?
　　Based on industry standards and practical application requirements,the glass layer thickness of the enamel glass reactor should meet the following requirements:1.0~1.5 mm for general chemical applications and 1.5-2.0 mm for highly corrosive environments.Excessive or insufficient thickness may affect performance,so it is necessary to choose the appropriate thickness according to specific working conditions and strictly control the production process.
