Acid resistant castable is mainly used to resist chemical erosion. The SiO in the castable is acidic oxide. So it will not react with acidic solutions. Ronghua acid proof castable has great present to resist acidic materials in high-temperature equipment. Compared with regular castable, the acid resistance is better. We will give customers a suitable price for castable.

Features of Acid Refractories Castable
- Excellent Acid Resistance: Acid refractories have excellent chemical resistance. Silica oxide is an acidic chemical material. It will not eroded by acidic solutions in the high-temperature environment. In this situation, using acid refractories in the equipment can effectively prolong the life cycle of industrial equipment.
- Good Refractoriness: The refractoriness of acidic refractory is 800-1000℃. Although the refractoriness is lower than refractory castable, it also can be used in the flue and chimney of the high-temperature equipment.
- Easy Construction: Acid refractory castable can save more construction time because it is easy to operate. Castable just need to add water and stir. It is more easily constructed than Ronghua refractory bricks. In this situation, many people tend to use acid refractory under suitable temperatures.
- Good Compressive Strength: Acid proof castable has good compressive strength. It can withstand high pressure in the industrial furnaces. In this situation, it can keep a steady structure of industrial equipment.
Applications of Acidic Refractories
Acidic refractories can used for the metallurgy industry, petroleum, chemical, and electric power industry. They can used as anti-erosion flue and chimney linings, acid storage tanks, pickling tank linings, nitric acid puncture tower linings, acid recovery furnace linings, and other container linings corroded by acidic high-temperature gas. On our website, we shared many cases. If you want to get more details, you can browse our case page.
