Acid-resistant Borosilicate Foam Glass Bricks

product description

Acid-resistant borosilicate foam glass bricks constitute an inorganic thermal insulation material, formed through the processing of borosilicate glass into closed-cell foam structural blocks. They combine the lightweight, low thermal conductivity, and non-absorbent properties of foam glass with acid corrosion resistance derived from their borosilicate composition, rendering them extensively applicable in chemical processing and cryogenic engineering.

The Characteristics of Acid-resistant Borosilicate Foam Glass Bricks

1 Using temperature range of acid resistant borosilicate foam glass brick: -196~ +450 ℃.

2. Acid resistant borosilicate foam glass brick is made up of countless independent airtight air vents, 100% closed hole structure, the airtight is good, do not influenced by the invasion of acid waste gas or sour liquid, the waste gas, moisture or condensing water within the chimney can not touch with the chimney directly.

3. Acid resistant borosilicate foam glass brick will has any chemical reaction with sulfuric acid, inferior sulfuric acid, hydrochloric acid, etc.  it is alkali proof, acid proof, not burning, and will not produce any poisonous gas.

4. The hot expansion coefficient of acid resistant borosilicate foam glass brick is little, bricks are bonded with acid proof elastic binder, even the temperature changed sharply, the system of the antiseptic inside lining is not destroyed.

5. Acid resistant borosilicate foam glass brick has little heat conduction coefficient, has good warm keeping performance, can keep the chimney waste gas temperature well, accelerate the discharge pace of the waste gas, and can solve the problem caused by the unbalanced heating and lengthen the service life of the chimney.

6. The construction work of acid resistant borosilicate foam glass brick is simple and convenient, the cycle of constructing is short, it is suitable for desulphurization and antisepsis of various steel chimneys, cement chimneys.

7. Acid resistant borosilicate foam glass brick is not wear out, service life is as long as the chimney.
