1.概况 耐火可塑料是一种以耐火材料为主,加入适当的粘土、化学胶结剂并掺入少量外加剂,经过混练制成的膏泥状物料,在规定的贮存期内具有良好的可塑性,烘烤后硬化成型的耐火材料。以高铝质可塑料为列。其主要理化指标为:Al_2O-3含量>60%,耐火度>1690℃,最高使用温度1400℃,荷重变形4%的温度>1320℃,烧后线变形<1%,耐压强度>196MPa,气孔率22~25%,热震稳定性>15次,容重2.1~2.4g/cm~3。 耐火可塑料一般可在现场按热工设备的具体形状及尺寸直接捣打施工。因此用可塑料捣打的炉衬整体性好,能增强气密性和抵
1. Overview Fire-resistant plastic is a refractory-based, by adding the appropriate clay, chemical cement and mixed with a small amount of admixture, made by mixing paste material, the provisions of the storage period has a good Plasticity, baked after hardening of the refractories. High aluminum plastic for the column. The main physical and chemical indexes are: Al 2 O 3 content> 60%, refractoriness> 1690 ℃, maximum service temperature 1400 ℃, load deformation 4% temperature 1320 ℃, burning line deformation 1%, compressive strength 196MPa, Porosity of 22 ~ 25%, thermal shock resistance> 15 times, bulk density of 2.1 ~ 2.4g / cm ~ 3. Fire-resistant plastic can generally be in the field by the specific shape and size of thermal equipment ramming construction. Therefore, the use of plastic ramming lining integrity, can enhance air tightness and arrived
