Introduction to common materials for exterior wall maintenance structure
The main materials of the external wall maintenance structure are aerated concrete exterior wall panels, prefabricated reinforced concrete exterior wall panels, glass fiber reinforced cement inorganic composite exterior wall panels and glass curtain walls.
1. Aerated concrete wall panel: aerated concrete wall board and silicon-containing materials such as sand, fly ash and tailings powder. After grinding and adding aluminum powder and other gas generating agent, mix and mix according to the ratio. After pouring, the gas forming is statically stopped, and the body is cut and autoclaved to form a lightweight porous building material.
2. Prefabricated reinforced concrete exterior wall panels: The exterior wall panels are both heavy components and meet the requirements of maintenance functions such as heat preservation, heat insulation and prevention of rainwater infiltration. Prefabricated reinforced concrete exterior wall panels have two main forms: single material. Exterior wall panels, composite exterior wall panels.
3. GRC composite exterior wall panel: is a siding made of glass fiber as reinforcing material, cement as cementing material, lightweight material as core-filling thermal insulation material and composite molding process.
4. Glass curtain wall exterior wall: The glass curtain wall is mainly composed of glass, skeleton and sealing material.
The main requirements for the maintenance structure of the outer wall of the high-rise building are: light weight, red thermal insulation performance, waterproof, durable, beautiful, simple construction and reasonable price.
Fiber Optic Light kits comes in two configurations -single sheathed or unsheathed strands of 0.25mm, 0.50mm, 0.75mm, 1mm, 1.5mm,2mm or 3mm diameter fibre, or as multiple sheathed strands of 0.75mm,1.0mm fibre.
Single strands of fibre give starry points of light and normally require no termination, whilst multi-stranded varieties are normally terminated with a ferrule to allow the attachment of an end fitting.
