无机玻璃钢风管是一种轻质高强的非金属材料，由改性的菱镁材料做胶结料，用抗碱玻璃纤维布做增强材料，并加入效果显著的改性菱镁添加剂而制成。无机玻璃钢风管管壁结构合理先进，能充分发挥材料的作用，在满足使用强度的前提下，提高了钢度，保证了产品的稳定性和可靠性，广泛应用于各类工业与民用建筑的地下室、车库、厂房以及人防工程等中的通风和排烟。
Inorganic FRP duct is a kind of lightweight and high strength non-metallic material. It is made of modified magnesite material as cementing material, alkali-resistant glass fiber cloth as reinforcing material, and modified magnesite additive with remarkable effect. Inorganic FRP duct wall structure is reasonable and advanced, which can give full play to the role of materials. On the premise of satisfying the use strength, it improves the rigidity and guarantees the stability and reliability of products. It is widely used in ventilation and smoke exhaust in various industrial and civil buildings, such as basements, garages, factory buildings and civil air defense projects.
