HIgh Density High Alumina Cement

【Product Features】

Durable
High-density high-alumina cement is made of high-quality high-alumina aggregate with Al₂O₃ content ≥70%, which has strong anti-scouring ability and a service life 2-3 times longer than ordinary refractory materials.

High-strength Structure
Its compressive strength is ≥70MPa, and its flexural strength is ≥8MPa. After hardening, its structure is dense and it can withstand thermal load and mechanical impact for a long time without cracking.

Suitable For A Variety Of Thermal Equipment
High-density high-alumina cement is suitable for various heat treatment furnaces, rotary kilns, preheaters, coolers, flue linings and other heat load systems in industries such as steel, electrolytic aluminum, cement, chemicals, waste incineration, and electricity.

【Frequently Asked Questions】

Q: What are the main components of high-density high alumina cement?
A: The main components of high-density high alumina cement are alumina (content ≥ 70%) and dicalcium silicate, containing a small amount of iron oxide, etc. It is made by high-temperature calcination and grinding, and has high density.

Q: What high-temperature equipment can it be used for?
A: It can be used for metallurgical kiln lining, glass melting furnace bottom, and industrial boiler refractory layer.

Q: Are there any special requirements for installing high-density high alumina cement?
A: The installation of high-density high alumina cement needs to be carried out in a dry environment (humidity ≤ 60%) to avoid direct contact with water. It needs to be poured in layers, and the thickness of each layer does not exceed 50mm.

Q: How to clean and maintain it daily?
A: You can use a dry soft brush to clean the surface dust. If there are stubborn stains, wipe it quickly with a small amount of clean water and dry it immediately to prevent moisture absorption.

Q: What precautions should be taken during storage?
A: It needs to be stored in a sealed moisture-proof iron barrel in a dry and ventilated place. The shelf life is 6 months and it must be used up within 3 days after opening.
