（1）、产品概述
HQ—DA惰性瓷球具有高强度、高化学稳定性和热稳定性的特性，它可以耐高温、高压和酸、碱、盐及各种有机溶剂的腐蚀，广泛应用于石油、化工、化肥、天然气及环保等行业，作为反应器内催化剂的支撑和覆盖材料，可缓冲进入反应器内液体和气体对催化剂的冲击，保护催化剂，并改善反应器内液体和气体的分布。 Inert ceramic balls have the advantages of high strength, high stabilities to chemical and thermal circumstances. It can resist the corrosion to acid, alkali, salt and all organic solvents. Being used as a supporting and a covering material of catalyst in reactors, oil refinery, chemical, fertilizer production, natural gas and environmental protection industries. The main role of these ceramic balls is to increase the distribution spots of gas or liquid, and to support and protect the activating catalyst with low strength.
