节煤炉外壳往往容易生锈腐烂,这是千家万户最烦恼的一件事。针对这一问题,我们利用非金属绝缘耐火材料和高强度阻燃粘合剂,进行配比试验,制成了永不生锈的节煤炉外壳。这种煤炉外壳厚度为一毫米,每个外壳重量1公斤左右,成本约1.5元,比同规格的金属外壳重量减轻1/2,成本降低1元以上(孝感价 Coal stove shell is often prone to rust and decay, which is the most troublesome thing for millions of households. In response to this problem, we use non-metallic insulating refractory materials and high-strength flame-retardant adhesives, ratio test, made of never rusting coal stove shell. The thickness of the coal stove shell is one millimeter, the weight of each shell is about 1 kilogram, the cost is about 1.5 yuan, which is 1/2 less than the weight of the metal shell of the same specification and the cost is reduced by more than 1 yuan
