【Frequently Asked Questions】

Q: What is the working principle of 70% high alumina refractory cement?
A: 70% high alumina refractory cement generates hydration products through the reaction of aluminate minerals and water, forming a hard structure, maintaining stability at high temperatures, and playing a refractory role.

 

Q: Where is 70% high alumina refractory cement mainly used?
A: 70% high alumina refractory cement is often used for masonry and repair of industrial kilns such as steel, glass, and ceramics, and is also suitable for lining casting of high-temperature pipes.

 

Q: How to clean tools that have been used with 70% high alumina refractory cement?
A: After use, the tools should be rinsed with clean water in time. If the cement has solidified, you can first use a scraper to remove the lumps, and then soak it in clean water and brush it.

 

Q: What should I pay attention to when installing 70% high alumina refractory cement?
A: When installing 70% high alumina refractory cement, ensure that the base is dry and clean, add water in proportion and stir evenly, and the construction environment temperature is not lower than 5℃.

 

Q: What are the requirements for storing 70% high-aluminum refractory cement?
A: 70% high-aluminum refractory cement should be stored in a dry and ventilated place to avoid moisture. Bags of cement should be kept away from the ground and walls. The shelf life is usually 3 months.
