Lightweight refractory castable light brick sand with cement, refractory powder and lightweight aggregate, their variety and amount of different properties are also different; superplasticizer admixture castable, water loss and strength increase is clear; incorporation of additional bulk density of small objects, light casting material can reduce the bulk density of the castable, improve its insulation performance, but the intensity decreases exponentially corundum castable, and the more the amount thereof, the more obvious. Therefore, based on thermal furnace conditions of use and the use of castable parts, reasonable preparation and selection of light brick refractory castable Zhejiang sand corundum castable to achieve furnace longevity and energy saving. Lightweight refractory castable preparation and molding, and finally to light castable refractory castable is basically the same, the difference is small lightweight aggregate density, easy to absorb water, so the mixing should say good lightweight aggregate, compulsory mixer poured in water before adding half the amount of water, wet mixing uniformity, coupled with refractory powder and cement, and add the remaining water mixing. When forming, lightweight aggregate easy to float, causing delamination, so vibration time should be shorter Fujian corundum castable, should be controlled. Light brick refractory castable in accordance with the requirements of the sand, forming the initial setting after mixing should be cured in a moist environment. 1 day Chaimo conservation, portland cement and cement CA-50 lightweight refractory castable test body, should continue conservation six days and two days respectively. Then, to test its performance. Light brick sand formulated refractory castable bulk density, typically 1.18-1.58 g? Cm3. Drying compressive strength greater than 6Mpa, with heating temperature, the strength decreased to 1300 ℃, the light casting material strength has gone up, which is caused by the powder is sintered. Buy light casting material, energy-saving choice for Tianjin Goodrich Goodrich saving light casting material is cement, high alumina fines, ceramic, plus a number of additives dispositions, the product has a light volume, high compressive strength , acid and acid gas corrosion. Insulation, thermal insulation, low water absorption, the construction is simple, there is a construction site of alkali corrosion best products at high temperatures. Workability is good, strong bond, the initial setting time and construction operational for a long time, fast growth strength, impermeability and strong, no acidification, easy to guarantee full dense masonry mortar joints, can significantly improve the chimney liner corrosion resistance wall tightness, integrity and lined, high chimney, high temperature flue duct liner ideal cementation material, can also be used in petroleum, chemical, non-ferrous metallurgical industries acid pools, tank and other acid project.
