Inorganic glass fiber reinforced plastic (GFRP) ducts are classified according to the performance of their binder materials, including those made with sulfate-based binders and glass fiber mesh cloth for hydro-setting inorganic glass fiber reinforced plastic ducts.
Two types of aerated magnesium oxide chloride cement pipes: one made of pipes and modified magnesium oxide chloride cement as the binder with glass fiber mesh, and the other with the binder hardening.
The pH value of the substance should be less than 8.8, and it should not cause alkaline corrosion to glass fiber.
Non-flammable inorganic glass fiber reinforced plastic ventilation ducts, made with modified cement as the binder, glass fiber fabric as the reinforcing material, and an effective third
Manufactured with a substitute for modified additives, the main technical key lies in the domestic advanced modification of the materials used, and structurally, it employs two different performance types.
A new process where bonding materials are compounded together. Non-combustible inorganic glass fiber ducts are mainly used for central air conditioning air supply in buildings with centralized refrigeration and heating systems.
Supplying hot air.
Non-flammable inorganic glass fiber reinforced plastic duct features
(1) Smooth, glossy appearance with rich colors
Non-flammable inorganic glass fiber reinforced plastic ducts are a composite structure, which not only effectively enhances product strength but also offers a variety of colors for selection in the produced products.
Choose from either all white inside and out or outer red with white inside. The surface is smooth and glossy, with an aesthetically pleasing and generous appearance.
(2) Excellent fire resistance properties
Non-combustible inorganic glass fiber air ducts are Grade A non-combustible materials, with better fire resistance than galvanized steel ventilation pipes.
(3) Good water resistance
Regular brand composite duct products are prone to water resistance, which is a major drawback. Ventilation ducts are often used in humid environments, and water resistance will shorten their service life.
Service Life – To address this issue, we have added waterproofing agents, ensuring that the specimens remain softer than 0.9 after being soaked in water for a month, exceeding the national规定的 standard.
Specification.
(4) Product is not prone to deformation
The hardening process of non-flammable inorganic glass fiber reinforced plastic ducts is a volume expansion process, and the subsequent drying process after hardening will result in shrinkage, along with uneven expansion.
Swelling and shrinkage can cause product deformation. To address this drawback, we have implemented effective modification measures, strengthened production control, and ensured proper product maintenance to resolve
Addressed the product's deformation issues.
(5) Good flexibility, no脆ification
Non-flammable inorganic glass fiber reinforced plastic ducts have a significant drawback of poor toughness and proneness to脆化. We have addressed this challenge by utilizing a well-designed formulation.
Title, indicator of toughness -- Initial crack deflection value ≥15%, unmodified ≤8%.
(6) Non-absorbent and non-salting
Ventilation duct surfaces without modification technology exhibit moisture absorption and brine reflux phenomena (a layer of salt frost and water droplets appear on the surface), affecting appearance and usability.
Effectiveness. The moisture-proof and salt back inhibitor we add effectively prevents the product from absorbing moisture and salting back, even in humid environments, without any damp feeling on the surface.
Additionally, non-flammable inorganic glass fiber reinforced plastic ventilation ducts also feature low production costs, heat insulation, lightweight strength, and corrosion and aging resistance, making them a popular choice in today's market.
Ideal new building materials products.
Non-flammable inorganic glass fiber ventilation duct applications and usage
Non-flammable inorganic glass fiber ventilation ducts are mainly used in industrial factory buildings, mines, civil air defense projects, and public building ventilation and air conditioning systems, such as textile factories.
Theatres, hotels, shopping malls, air-raid shelters, etc. Also suitable for manufacturing smokestacks for the discharge of smoke and toxic gases in the chemical industry and other industries, as well as for water storage and various installations.
Storage tanks for oils and chemical liquids, as well as downspouts for construction projects.
