Product Features of Foshan Auditorium Chair Production Base
1. The seat and back sponge of the auditorium chair: real material, high resilience, never deformed. It adopts aluminum alloy mold and high-quality PU foam material and high-density cold foaming to shape. The seat density is 60KG/M3, and the back density is 45KG/M3. It has heat preservation, heat insulation, sound absorption, shock absorption, flame retardant, anti-static, and good air permeability.
2. Auditorium seat and back inner panel: high-quality plywood is formed by bending with a mold, and the thickness is 10 mm. Screw fixation is watermelon screw fixation with double-sided grip
3. Adhesive shell of auditorium chair: It is made of high-quality PP (polypropylene) multi-element composite material by die casting, with a thickness of 3mm. Book nets can be added to the back rubber shell.
4. Seat rubber shell: It is made of high-quality PP (polypropylene) multi-element composite material by die-casting, with a thickness of 4-6 mm; with a silencer hole, which effectively removes environmental noise; the seat shell is designed with reinforcing ribs for use It is not easy to break.
5. Return function: The seat bag supporting shaft is a through-type cold drawn round steel with a diameter of not less than 14mm. Seat return options:
(1) Spring plus steel frame return structure: The spring adopts ϕ3.0 spring steel with a stroke of 38mm, which is durable, fast and effective, and there is no failure;
(2) Gravity return: the use of stable density/weight, non-powdering marble stone to ensure that the return time error is within the minimum range, the return is stable, and the return function will never fail.
6. Fabric: The seat and back material are made of special fabric or West leather, wear-resistant and non-fading, and can be flame-retardant and anti-fouling. Manual sewing, high temperature and low temperature resistant "strong environmental protection glue" sticks to the sponge, and then pulls the thread to fix it. The appearance is smooth and wrinkle-free.
7. Writing board: "built-in" folding writing board (can be equipped with "rear-mounted" folding writing board), can be stored in the armrest frame, the panel is made of high-density medium-density fiberboard, and the surface is pasted with "cold-pressed fireproof panel". The surrounding PU edge is 18mm thick.
8. Side panels: The side panels on both sides of the seat frame are built-in design, which is more stable and durable than the traditional external buckle type. It is made of high-quality high-density board or PP board with a thickness of 4mm.
9. Bracket and armrest side frame: 2mm high-quality cold-rolled steel is used for stamping and folding forming, which has the load-bearing and anti-bending function of angle iron. All hardware parts are processed by grinding, polishing, rust removal, phosphating, electrostatic powder spraying, high temperature furnace and other processes. Ensure that the salt spray for 400 hours or the salt bath for 100 hours, the paint film corrosion resistance test does not rust, and the paint film adhesion exceeds the second level.
10. Water cup/beverage holder: A "cylindrical water cup holder" or a "foldable square water cup holder" can be installed at the lower front end (or lower end of the rear) of the armrest.
11. Fire-resistant and flame-retardant: According to the needs of fire-fighting safety, different materials can be selected for flame-retardant. The flame-retardant is produced according to the national standard:
(1) Low-grade flame retardant fabric: soak in environmentally friendly flame retardant and then dry;
(2) High-grade flame-retardant fabric: activated carbon is strongly adhered to the back of the fabric to achieve permanent flame retardancy.
(3) Sponge surface flame retardant: the environmentally friendly flame retardant is sprayed on the sponge surface, sucked into the sponge surface, and then air-dried;
(4) Sponge flame retardant as a whole: the flame retardant is fully mixed with the foaming material, and the foam is integrated. Own foaming workshop and self-made flame-retardant sponge have great cost and quality advantages.
12. Foot soleplate: It has been processed with [reinforced lacing] (patented), which doubles the bearing capacity of the "most easily deformed and damaged part" of the seat (see the comparison chart below).
13. Standing foot: The foot tube is made of 80X40XT1.5 high-quality square tube welded by carbon dioxide, and processed by processes such as grinding, polishing, rust removal, phosphating, electrostatic powder spraying, and high temperature furnace.
