FRP duct can be divided into inorganic and organic. Inorganic FRP and organic FRP have different compositions, properties and functions, which are suitable for different scenes.

一、玻璃纤维氯氧镁水泥通风管道（无机玻璃钢风管）

1、 Glass fiber magnesium oxychloride cement ventilation duct (inorganic FRP duct)

无机玻璃钢是指采用轻烧氧化镁、稀盐酸、盐卤、黄河沙、防水粉、树脂、促进剂、固化剂、地板蜡、玻璃布等制作而成，也叫氧化镁。

Inorganic glass fiber reinforced plastic is made of light burned magnesium oxide, dilute hydrochloric acid, bittern, yellow river sand, waterproof powder, resin, accelerator, curing agent, floor wax, glass cloth, etc., also known as magnesium oxide.

玻璃纤维氯氧镁水泥通风管道（亦称无机玻璃钢风管）是一种新型环保通风管道，按其用途可分为P类和D类。P类风管主要应用于公用建筑，人防工程及一般需要安装通风及空调设施的工业厂房和矿井等的通风管、防、排烟管；D类风管主要应用于住宅建筑的通风、排油烟风道。无机玻璃钢的韧性较差于有机玻璃钢，易返卤，裂口；防水性能仅次于有机玻璃钢；可净化空气，能吸收空气的二氧化碳；可降解，具有物理系数上的优点。

Glass fiber magnesium oxychloride cement ventilation duct (also known as inorganic FRP duct) is a new type of environmental protection ventilation duct, which can be divided into P and D categories according to its purpose. Class P air ducts are mainly used in public buildings, civil air defense projects, industrial plants and mines that generally need to install ventilation and air conditioning facilities, such as ventilation ducts, smoke control and exhaust ducts; Class D air ducts are mainly used in ventilation and fume exhaust ducts of residential buildings. The toughness of inorganic glass fiber reinforced plastics is poorer than that of organic glass fiber reinforced plastics, which is easy to return halogen and crack; The waterproof performance is second only to that of organic glass fiber reinforced plastic; It can purify the air and absorb carbon dioxide from the air; It is degradable and has the advantage of physical coefficient.

二、玻璃纤维增强塑料通风管道（有机玻璃通风管道）

2、 Glass fiber reinforced plastic ventilation duct (plexiglass ventilation duct)

有机玻璃钢根据采用的纤维不同分为玻璃纤维增强复合塑料（GFRP），碳纤维增强复合塑料（CFRP），硼纤维增强复合塑料等。它是以玻璃纤维及其制品（玻璃布、带、毡、纱等）作为增强材料，以合成高分子树脂作基体材料的一种复合材料。

According to the different fibers used, PMMA can be divided into glass fiber reinforced plastics (GFRP), carbon fiber reinforced plastics (CFRP), boron fiber reinforced plastics, etc. It is a composite material with glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as reinforcement and synthetic polymer resin as matrix material.

玻璃纤维增强塑料通风管道（亦称有机玻璃钢风管）是空调、除尘、通风、净化以及气体输送等理想的管道材料，它具有重量轻、耐腐蚀、强度高、耐老化、特别适用于潮湿河有酸碱的场合。有机玻璃钢风管采用不饱合聚酯树脂和玻璃纤维制成。树脂型号可根据风管用途不同选用相应型号的树脂。玻璃钢风管内表面平整光滑、外表面整齐美观，厚度均匀，美观大方。玻璃钢风管可以按用户要求做成各种颜色，色泽明快，可以按用户要求做成阻燃风管，氧指数不小于30。玻璃钢风管适用于输送腐蚀性气体的通风系统中；当通风系统要求外观色泽美观时，也可采用玻璃钢风管。

Glass fiber reinforced plastic ventilation duct (also known as organic glass fiber reinforced plastic duct) is an ideal pipe material for air conditioning, dust removal, ventilation, purification and gas transmission. It has light weight, corrosion resistance, high strength, aging resistance, and is especially suitable for wet rivers with acid and alkali. The plexiglass steel air duct is made of unsaturated polyester resin and glass fiber. The resin model can be selected according to the different uses of the air duct. The inner surface of FRP air duct is flat and smooth, the outer surface is neat and beautiful, the thickness is uniform, and the appearance is generous. FRP air duct can be made into various colors according to user requirements, with bright color. It can be made into flame-retardant air duct according to user requirements, and the oxygen index is not less than 30. Fiberglass reinforced plastic air duct is applicable to the ventilation system conveying corrosive gases; When the ventilation system requires beautiful appearance and color, FRP air ducts can also be used.
