First of all, Kerui Refractory sincerely thanks this Colombian customer for his long-term trust and support for Kerui acid resistant brick products! In June 2025, we shipped a new batch of high-quality acid resistant brick products to Colombia. We specially prepared customized solutions for this customer to meet the professional needs in the fields of chemical equipment corrosion protection and activated carbon regeneration.
Acid Resistant Bricks Shipped to Colombia in June 2025
The acid resistant bricks we plan to ship to Colombia in June 2025 include:
- Standard acid resistant brick linings: 230×113×40mm regular size;
- Features: water absorption <0.5%, acid resistance >99.8%;
- Application: acid trenches, acid wells, acid storage tanks and impacted ground, etc.
- Supporting materials: acid-resistant mortar, acid-resistant cement.
Acid Resistant Bricks for the Conical Bottom of Chemical Reactors
We learned that this customer recently encountered special needs in the anti-corrosion project of the conical bottom of the chemical reactor-special-shaped acid resistant bricks are needed to reduce the use of mortar and improve construction efficiency. This is exactly the core expertise of Kerui.
- Precisely match the equipment structure: Customized according to the special geometric shape of the conical bottom, it can achieve seamless fitting and reduce the number of joints by 30-50%;
- Significantly reduce the amount of glue: The specially designed bite structure can reduce the amount of glue used by about 40%, while improving the overall structural strength;
- Excellent corrosion resistance: In addition to hydrofluoric acid and hot phosphoric acid, it has excellent corrosion resistance to warm chlorine brine, hydrochloric acid, sulfuric acid, nitric acid and other acids and alkalis of any concentration at room temperature;
- Reduce maintenance costs: The one-piece molding design reduces weak links and extends the maintenance cycle.
Overall Upgrade Plan for Refractories in Activated Carbon Regeneration Production Line
In response to the refractory material upgrade needs of the rotary kiln of the activated carbon regeneration production line mentioned by the customer, we have specially developed a comprehensive refractory solution to replace traditional refractory mud with a more advanced refractory brick and ceramic fiber combination system.
- High temperature resistance: Our refractory bricks can withstand temperatures above 1350℃, which is much higher than the limit of ordinary refractory mud;
- Thermal shock stability: The special formula gives the product excellent thermal shock stability and reduces the risk of cracking;
- Energy-saving effect: The thermal conductivity of the ceramic fiber module is only 1/10 of that of traditional materials, significantly reducing heat loss;
- Long service life: Although the initial investment is about 20-30% higher than that of refractory mud, the service life can be extended by 3-5 times;
- The thermal energy utilization rate is increased by 15-20%, which can save a lot of fuel costs every year;
- Maintenance intervals are extended to reduce production stoppage losses;
- Environmental compliance: All materials meet international environmental standards.
