耐酸砖

产品概述

耐酸砖,是以石英、长石、粘土为主要原料,经高温氧化分解制成的耐腐蚀材料,具有耐酸碱度高,吸水率低,在常温下不易氧化,不易被介质污染等性能,除氢氟酸及热磷酸外,对温氯盐水、盐酸、硫酸、硝酸等酸类及在常温下的任何浓度的碱类,均有优良的抗腐作用。广泛应用于石油、化工、冶金、电力、化纤、造纸、制药、化肥、食品、乳业、果汁、电镀室以及塔、池、罐、槽等防腐工程,并在地下污水道和露天地面等工作地都可发挥其耐腐蚀力。

产品特点

1)耐酸砖板具有耐酸度高、耐温耐酸效果好,吸水率低、在常温下不易氧化、不易被介质污染等性。
( 2)
除氢氟酸以及热磷酸外,对湿氯、盐水、盐酸、硫酸、硝酸等酸类以及在常温下的任何浓度的碱类均有优良的抗腐蚀作用。

使用说明

1、一般环氧树脂,耐酸胶泥、耐酸水泥铺贴,铺贴时可根据上述生产厂家产品使用说明书进行施工;
2
、用草酸清洗混凝土表面,达到酸碱中和;
3
、工业瓷耐酸砖,间缝宽度约8--10mm,间缝深度与砖厚相平为宜,以防泄露;
4、铺贴完毕后应用草酸冲刷表面,以助于更加牢固。
