1.Description
Our supply range of high alumina bricks are useful in the construction of steel refining furnaces, glass tanks, ceramic kilns, enamel kilns and rotary cement kilns. The high alumina bricks comprise of a blend of alumina and ferrous content and their apparent porosity is 15 to 23%. They have high refractoriness and can sustain themselves easily even in high temperature. This is the reason why they are used as high temperature equipments in various industries. These high alumina bricks are highly resistant to corrosion due to metal fluid and oxidation.

2.Feature
1. High refractoriness.
2. Good spalling resistance and wear resistance.
3. Good corrosion resistance.
4. Good thermal shock resistance.
5. High mechanical strength.
6. High-temperature creep rate is low.

3.High alumina bricks Application:

High alumina brick is widely used for widely used in blast furnaces, hot bast stove,steel ladle lining, reheating furnace, cement kiln, tunnel kiln,boiler, coke oven, carbon furnace,glass kiln , steel smelting furnace and various kiln lining and thermotechnical equipment, etc.

耐酸瓷板

生产工序一般为选料、配料、粉碎、沉浆、喷雾干燥、压坯成型、干燥、烧结、检验及包装等步骤。耐酸砖成分是二氧化硅,它在高温焙烧下形成大量的多铝红柱石,这是一种耐酸性能很高的物质.由于耐酸砖结构紧密,吸水率小,所以在常温下也可耐任何浓度的碱性介质,但不耐温度高的熔融碱.耐酸砖含有二氧化硅70%以上,经烧结而成,在化学工业中多应用于砌酸沟、酸井、贮酸库及载酸大的受冲击地面。

耐酸砖有很多的别名,又叫耐酸瓷砖,耐酸瓷板,耐酸耐碱砖等等,因其具有良好的防腐性能,吸水率低,使用时间长,耐压抗磨等性能深受广大消费者的喜爱。

1.产品特性:
(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。

2.产品应用
我公司生产的耐酸砖板广泛应用于石油、化工、制药、食品、造纸、化肥、农药、化纤、纺织、冶炼、电厂等行业,以及塔、池、罐、槽的防腐内衬,并在污水处理工程方面和露天地面等工作场地都发挥其耐酸防腐作用。耐酸砖能耐除氢氟酸、热磷、浓碱之外的大多数介质,对湿氯盐水,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。

3.使用说明
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; 用草酸清洗混凝土表面,达到酸碱中和; 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; 铺贴完毕后应用槽酸冲刷表面,以助于更加牢固。
