铸钢保温冒口套的制作,有的厂用粉煤灰作主料,再添加膨胀珍珠岩、硅藻土、水泥,耐火纤维等,也在用烟道灰作主料,另加石英粉、水玻璃等,使用效果都不错,但保温套的制造工艺较为复杂,且需要一定的设备才能办到。我厂锅炉房烟囱里捕集下来的烟道灰呈空心球状,容重只有343公斤/米~3,适于作保温材料。虽然有增炭问题,但只要有适当的防范措施,还是可用的。我们确定以烟道灰作主料而不用打成保温套的办法进行试验。
Casting steel insulation riser sets of production, and some plants fly ash as the main ingredient, then add the expanded perlite, diatomaceous earth, cement, refractory fibers, are also used as raw material flue ash, plus quartz powder , Water glass, the use of effects are good, but insulation cover manufacturing process is more complex and requires some equipment to do it. The flue gas trapped in the chimney of the boiler room in our factory is hollow and spherical, weighing only 343 kg / m ~ 3, suitable for thermal insulation materials. Although there is a problem of increasing carbon, it is still available as long as there is proper precautionary measures. We have decided to use flue ash as the main ingredient instead of being labeled as a thermal insulation sleeve.
