Seat description:
1. The design, selection and installation of the seat are in line with the design of the gymnasium, which is beautiful, comfortable, safe, durable, and easy to install, maintain and manage. The chair surface adopts the hollow blow molding manufacturing process, and selects high-density polyethylene material (HDPE) for one-time processing and molding. It has the characteristics of rounded edges and corners on the seat surface, relatively concentrated molecular weight, high bonding strength at the junction, excellent aging resistance, and excellent impact resistance.
High-density polyethylene (HDPE) is a milky white translucent waxy solid with a molecular weight of 100,000 to 300,000. The density of homopolymer is generally 0.955～0.965, linear structure, few branches, and crystallinity of 80%～90%. HDPE has the smallest degree of branching, and the molecules can be packed tightly, so the density is the largest (0.941g/cm3～0.965g/cm3) and the crystallinity is high. It has high rigidity and toughness, good mechanical properties and high operating temperature. Anti-aging, impact resistance, low temperature resistance and oil resistance are good. Polyethylene (HDPE) has little water absorption, is non-toxic, and has excellent chemical stability.
2. Overall dimensions of the chair surface: Width × Depth × Height = 430×475×420 (mm), the thinnest part of the seat is not less than 4mm. There is a water seepage hole in the most concave part to ensure that there is no water on the chair surface. The weight of the seat surface is 2.7KG, and the weight deviation is ±100g. The seat can carry more than 200kg and is impact resistant. The chair surface is loaded with 960N × 100,000 times, and the chair back is loaded with 330N × 100,000 times. The high and low temperature resistance requirements of the seat are +80°C to -60°C. The overall service life is ≥10 years.
3. The color of the seat group: determined by the owner, see the color chart for the color of the seat.
Accessories:
Bracket: It adopts precision aluminum pressure casting suspension bracket with polished surface and plastic spraying (the same color as the seat). It has the characteristics of beautiful appearance, dense structure, high strength, impact resistance and non-corrosion.
Connecting the round pipe: the outer diameter is Φ32mm thick galvanized pipe, and the end of the round pipe is sealed with a rubber plug.
All steel components: After silane treatment, the surface is oxidized and galvanized to enhance its corrosion resistance.
Fasteners: The seat, connecting plate and bracket are connected with Jinyi screws and cushioned soft pads. The bracket is connected with the side of the stand step by expansion bolts, and the connection is firm and not loose.
(Aluminum) seat number and row number setting: the seat number is set on the backrest, embedded design; the row number is set on the side of the seat on both sides of the aisle, using the same plastic row number seat as the seat, embedded installation .
Seat features:
The seat surface adopts Japanese formula and technology, and is produced by all Japanese imported production lines, South Korea imported high-density polyethylene material, and Dainippon Ink (DIC) color masterbatch, which has good performance in anti-aging, flame retardancy and water repellency. The seat surface adopts a hyperboloid and hollow double-layer structure, which greatly improves the strength of the seat and meets the safety of use in public places.
When designing the seat, the parting surface is considered on both sides of the seat surface, and the pre-embedded nuts are on the back and side of the seat surface to avoid accidental injury to people. The curve is naturally smooth and smooth, the surface is smooth and smooth, and the overall feel is pleasing to the eye.
The suspension bracket is made of aluminum alloy, and the surface is polished and the electrostatic spraying process is used to ensure the surface quality, corrosion resistance and strength of the product to the utmost extent.
The bracket is installed with special expansion bolts, and the perforation is uniform to ensure that the waterproof layer of the steps is not damaged, so as to ensure the installation strength and prevent water leakage from the steps.
