Production process of environment-friendly brucite composite insulation board
The invention belongs to the field of insulation boards, and particularly relates to a production process of an environment-friendly brucite composite insulation board. The process comprises the following steps of material preparation, wheel grinding, winnowing, impurity removal, dissolution, pulping, papermaking, drying, leveling and edge cutting. The composite insulation board has good heat preservation effect, low thermal conductivity, and improved heat efficiency, is energy-saving, pollution-free, free of dust emission, free of harm and toxicity, high in compressive strength which is twicethat of a traditional ceramic fiber plate. The composite insulation board is suitable for heat preservation and insulation of the bottom of a large electrolytic cell with the power being 400 KA or above, and is high in toughness, bendable, capable of protecting a calcium silicate plate against breakage and low in manufacturing cost which is a half of the cost of a traditional heat preservation material ceramic fiber plate.
本发明属于保温板领域，尤其是一种环保水镁石复合保温板生产工艺，包括如下步骤：准备材料、轮碾、风选、除杂、溶解、制浆、抄取、干燥、整平和切边。本发明保温效果好，导热系数低，提高了热效率，节能环保无污染，无粉尘排放，无毒害，同时，抗压强度大，是传统陶瓷纤维板的两倍，适合400KA以上大型电解槽底部保温隔热使用，韧性强，可弯曲，可保护硅钙板不断裂，且造价低廉，是传统保温材料陶瓷纤维板的二分之一。
