Light Weight Mullite Insulation Brick can be widely used as lining or insulation layers of various industrial furnaces and kilns in metallurgical industry, machine building industry, ceramic industry, chemical industry. Brickwork with refractory slurry should follow the following principles: (1) to deal with all kinds of refractory slurry pre experiment and pre laying brick front, confirm the bonding time, different mud initial setting time, consistency and water; (2) Modulation of different mud to use different instruments, and timely cleaning; (3) Modulation is not homogeneous slurry to use clean water, water should be accurate weighing, blending uniformly, adjusted with the use. Have good hydraulicity and modulation of hard mud shall not add water use, has the initial setting of mud may not continue to use the; (4) Modulation with phosphate mud to ensure refractory material time trapped provisions, with the use of post set, well modulated mud arbitrarily diluted with water. This kind of mud for corrosive shall not be in direct contact with the metal shell. We take the zero defect management idea, through the refractory production process from beginning to end. All the time since, in the pursuit of perfect quality at the same time, also constantly improve the service system, concerned about each of your needs, to provide professional sales and technical service for you. http://www.yilongrefractory.com/news/Modulation%20principle%20of%20slurry%20used%20for%20refractory%20brick.html
