How to judge the quality of enamel storage tanks?

The quality of enamel storage tanks can be judged from the following aspects:

1. Appearance and coating quality: The surface of high-quality enamel storage tanks should be smooth, evenly coated, and free of defects such as cracks, notches, fish scale explosions, porcelain peeling, explosion points, cracks, boiling marks, pores, and exposed black. ‌

2. Enamel thickness: The enamel layer thickness should be between 0.15-0.5mm, and the enamel layer should be uniform and continuous. ‌

3. Tightness: A good enamel storage tank should have strong adhesion, that is, the porcelain layer should be tightly bonded to the metal substrate and not easily detached.

4. Impact resistance and thermal shock resistance: glass lined storage tanks should have certain impact strength and thermal shock resistance to adapt to different usage environments and conditions. ‌

5. Chemical properties: Enamel storage tanks should be resistant to boiling water and cold acids, and the enamel should not contain harmful substances to the human body, such as lead, cadmium, arsenic, antimony, etc. ‌

In summary, judging the quality of enamel storage tanks requires comprehensive consideration of multiple aspects such as appearance, enamel thickness, adhesion, impact resistance, heat shock resistance, and chemical properties. ‌‌
