Product Introduction

Acid-resistant and anti-peeling brick is a new type of acid-resistant and anti-structural peeling material developed by our company according to the feeding characteristics of titanium dioxide kiln. The product uses low-aluminum mullite as the main raw material, adds nano-composite materials, and the pores exist in a closed and isolated manner. Ceramic glass body is formed at high temperature, which effectively prevents acid from eroding refractory materials. It is an ideal long-life material for preheating zone of titanium dioxide kiln.
