高强度低气孔率耐酸砖的研制与生产

THE DEVELOPMENT AND PRODUCTION OF HIGHER STRENGTH AND LOWER POROSITY ACID-PROOF BRICK

本文详细叙述了高强度低气孔率耐酸砖的研制过程,指出合适的原料是生产该砖的关键所在。研制的耐酸砖主要性能指标为:耐压强度≥70MPa,显气孔率5～8％,耐酸度≥98％。为国内大型烟囱的内衬砌筑提供了优良的建筑材料。

The article gives a detailed description of the developing process of higher strength, lower -porosity & acid-proof brick, and it point ont that the key to the manufacturing of this kind of brick is the snitable raw material. The main features of the acid -proof brick areModulus of rapture ≥70 MPa;.Porosity 5~8%;Acid-resistance ≥98%The brick can serve as high standard consturction material for the lining structure of big chimneys.
