Acid resistant refractory bricks

Acid resistant refractory bricks, plate and pipe: 1. good acid resistance 2. can be made according to requirements

 Acid resistant refractory bricks are used as inner lining for drying, absorption, tower and reactor in chemical plant, chemical fertilizer plant and sulfuric acid plant or used as inner lining for anticorrosive pools and channels and covered the anti acid ground etc.

Acid resistant brick is a kind of acid-proof product that takes many mine products with inorganic and nonmetal as raw material, via crashing, grinding , classification of the integrated grain separately, And then via molding and shaping by pressing , high temperature burning, etc.

PXZT high temperature alumina bricks are designed to increase the insulation with its lower thermal conductivity measures at higher temperatures. These alumina bricks are made with superior raw materials to improve strength, insulation and overall performance at higher temperatures. When exposed to the higher temperatures, the typical alumina bricks should not expand much which should lead to better performance and longer life.

Typical alumina brick sizes are for 4.5 x 9 x 2.5'' and 4.5 x 9 x 3''Other shapes made upon request.
