Refractory plastics in recent years in the number and range of application have great development, initially only for now, not only from the furnace bottom pipe wrap and soaking furnace mouth, and there have been entirely in plastic can stove. Refractory plastics compared with refractory concrete, there is in the raw material composition of similarities include aggregate, cement and additives, the difference is added to the plastic raw clay to a class of plasticizers, the material has plasticity. Depending on the different aggregates, fire-resistant plastic can be divided into clay, high alumina, magnesia, silica, quality and so on. China currently used are based on phosphate - clay as binding agent aluminum sulfate refractory to plastic. Ceramic fibers can be made of plastic using clay clinker aggregate, the aggregate is currently used flint size of less than 10mm of clinker containing aluminum oxide 46% silica 52%, and is required to bear angular, aggregates should be better The volume stability. Because plastic can be doped with a certain number of raw clay, so the drying shrinkage and heating requirements, such as excessive shrinkage cracks occur even destruction. Therefore, the aggregate can not be too thin, size appropriate to tie. To control the temperature shrinkage, such as adding high-alumina powder as admixture Shanxi lightweight refractory castable manufacturers, relying on free bauxite-alumina and silica clay, during heating secondary mullitization, produce expansion to offset the contraction caused by Inner Mongolia clay lightweight refractory castable manufacturer of plastic volume stability remains available. As China's urbanization process accelerated, increasing urban population, urban garbage and waste materials are also increasing year by year, in order to achieve pollution and resource recycling, the most effective way is to use municipal solid waste incineration and melting treatment and waste. Incinerators and melting furnaces also require refractories. Incineration Japan accounted for about 4% of refractory consumption. Our No detailed statistics. China's population, with the development, waste incineration, no less refractories. Incinerator lightweight refractory castable manufacturer of many types, such as furnace formula, fluidized bed Jilin lightweight refractory castable manufacturers, rotary kiln and so on. Incinerators have refractory products and refractories unshaped refractory materials, products are mainly refractory, aluminum bricks and silicon carbide bricks. Uncertainty mainly refractory clay and silicon carbide castable high alumina clay casting material.
