Cement binder for refractory castable, the last decade is widely used in engineering. For a long time, in the winter construction and winter maintenance, has been applied to refractory masonry clay binder method, even if the furnace construction is completed, when it is not immediately put into the oven, still using insulation measures, and to keep it winter at + 5 ℃ environment. Generally can not be put into the year. This is bound to spend a lot of manpower, materials and energy. Tianjin Gute refractory castable for winter construction has brought great convenience, and can save a lot of energy and money, there are clear economic benefits of this type of furnace lining construction and equipment of universal significance. Lightweight refractory castable light brick sand with cement, refractory powder and lightweight aggregate lightweight castable, its variety and amount of different properties are different; superplasticizer admixture castable, water loss and strength is increased, is evident; the incorporation of additional material accumulation density of small, lightweight castable castable reduces bulk density, improve its insulation properties, but the intensity decreased exponentially, and the more the amount is more obvious. Therefore, based on thermal furnace conditions of use and the use of castable parts, reasonable preparation and selection of refractory castable light brick sand to reach the 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 lightweight aggregate density is small, easy to absorb water, so the mixing should say good lightweight aggregate Qinghai lightweight castable, pour compulsory mixer, add after the first half of the water consumption 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, 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 castable lightweight Yunnan, Gansu decreased intensity light casting material, to 1300 ℃, the light casting material strength has gone up, which is the powder is due to sintering. Qinghai lightweight castable, lightweight castable, Tianjin Goodrich Goodrich provided by the Tianjin Science and Technology Co., Ltd. energy saving. Tianjin Gute energy saving Technology Co. (www.tjgtcl.com) strong, credible, in Tianjin fire, fire prevention materials industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the Tianjin Goodrich and you hand into the brilliant, for a better future!
