Product Description

Phosphate bonded high alumina brick from china

Alumina Block Phosphate Bonded High Alumina Brick with Fe2O3 Content of ≤2.0%

Phosphate combined high alumina brick is a kind of chemical combines high alumina refractory item, which is made by using a phosphoric acid solution or aluminum phosphate solution (aluminum dihydrogen phosphate, PA-80 glue, etc.) as a binder, bauxite clinker as aggregate, press molding, and then finished by firing in the 500-600C temperature.

Phosphate combined high alumina brick(referred to as phosphate brick) is With phosphoric acid solution and high-alumina brick combination; and wear-resistant phosphate combined high alumina brick (referred to as wear-resistant brick) is with aluminum phosphate solution and high-alumina brick combined together. The latter has a higher compressive strength.

Phosphate combined high alumina brick applications are: electric furnace top, cement rotary kiln transition zone, cooling zone and cement shaft high temperature zone.

Technical requirements for phosphate combined with high alumina bricks
Phosphate-bonded high-aluminum brick is made of high-alumina bauxite clinker as aggregate and fine powder, phosphoric acid or aluminum phosphate as binder, semi-dry pressed and heat-treated from 400 ° C to 600 ° C. Phosphate combined with high alumina bricks can be divided into two codes according to the bonding agent:
1. Phosphate combined with high alumina brick (referred to as phosphate brick), the binder is a concentration of 42.5%~50% phosphoric acid solution. Codenamed P;
2, aluminum phosphate combined with high-aluminum wear-resistant brick (referred to as wear-resistant brick), the binder is a solution of industrial phosphoric acid, industrial aluminum hydroxide, the molar ratio is Al2O3: P2O5 = 1:3.2. Codenamed PA.

Characteristics of Phosphate bonded high alumina bricks:
(1) Higher strength and good wear resistance.
(2) Good chemical resistance. (Its alkali resistance is better than clay bricks and high alumina bricks)
(3) Good thermal shock resistance.
(4) The load softening temperature is higher. Therefore, it is often found in the transition zone of the rotary kiln, the kiln mouth, the kiln door cover, the lining of the cooler and other parts where the refractory bricks are easy to loosen and fall.
