低铝铬红柱石耐碱砖

The Low Aluminum Chromium Andalusite Alkali Resistant Bricks


特点：该砖采用焦宝石和红柱石为主要原料，外加氧化铬、微粉和增塑剂，采用高吨位压机成型，具有较低的气孔率，由于其致密并含有较高的玻璃相，可以有效阻挡碱的渗透侵蚀和缓冲与碱反应产生的膨胀，广泛应用于高钠盐、高钾盐等强碱腐蚀环境。

 Features: The brick is made of pyrophyllite and Andalusite as the main raw materials, with chrome oxide, micro powder and plasticizer added. It is formed by a high tonnage press, and has low porosity. Because it is compact and contains high glass phase, it can effectively block the penetration erosion of alkali and buffer the expansion caused by the reaction with alkali. Widely used in strong alkaline corrosive environments such as high sodium and high potassium salts.
