Seat and back inner board

Using high-quality plywood to be formed by injection molding, the appearance of the back plate is curved, beautiful and curvaceous, thicknesss is 9mm

Seat and back shell board

The seat back outer panel is made of 15mm high-quality high-density hardwood multilayer board by injection molding, painted
finish, formaldehyde emission is 0mg/m³. And TVOC≤0.02mg/M²·h, the seat board is equipped with unique honeycomb sound-absorbing
vents. Ensure good breathability of the seat and noiselessness of the entire venue

Armest

385mm±2mm*62mm±2mm*26mm±2mm oak board is processed and formed through multiple processes. All exposed surfaces of solid wood are
treated with high-grade polyurethane environmentally friendly baking varnish. The surface is crystal clear, scratch-resistant, no
color change, and durable

Recovery system

The automatic turning spring and hydraulic damping recovery mechanism is adopted, so that there is no impact or noise during the
recovery, and it can be used for more than 200,000 times without failure. The recovery speed can be adjusted according to the
user's needs. The method is simple, reliable, and can be greatly improved. The service life of the seat

Seat

The seat bag contains 1.5mm high-quality cold-rolled steel plate stamped and welded, and the thick iron frame + plywood structure
has abandoned the wooden frame + plywood structure that is still widely used in the market. It has stronger bearing capacity, is
not easy to deform and break, and is more durable.

Writing pad

The built-in folding writing pad adopts aluminum alloy support structure with aluminum alloy yards, and the panel adopts
melamine board. When not in use, it can be stored in the armrest, which is extremely convenient to use, saves space, and fully
meets the load-bearing requirements when writing. size is 270*237*15mm

370±2mm, the lower end width is 255mm±2mm, the lower end width is 255mm±2mm, and the lower end width is 155mm±2mm. ±2mm, covered
with sponge and hemp, and use movable buckle, easy to disassemble

Armrest leg and frame

Leg:It is made of high-quality aluminum alloy by injection molding. The shape is beautiful and the craftsmanship is sophisticated. The
surface of the tripod is smooth and free of burrs, and there is no welding trace on the whole. The surface of the tripod is
treated with anti-oxidation and high-temperature spraying treatment to improve the powder adhesion. Strong, to ensure that the
tripod is resistant to corrosion, rust and color. The total height of the tripod: 234mm±2mm, the specification of the connection
position between the top of the tripod and the armrest frame is: length 147mm±2mm, width 65mm±2mm, thickness 10mm±2mm, sole
specifications: length 406mm±2mm, width 55mm±2mm, height 32mm ±2mm, the distance between the front and rear center holes of the
foot board foot hole is 361mm±2mm. The overall design of the tripod conforms to the principles of mechanics and ergonomics, with
uniform force, impact resistance, and durability. Both sides of the tripod are equipped with reinforcing ribs to strengthen the
seat. The stress point and strength of the chair, the tripod is fixed to the ground with M8 expansion screws + M12 expansion glue,
and the surface snap-fit PP rubber cover is embedded, which plays a dust-proof and beautiful effect. a length of 405mm±5mm, a lower end length of 245mm±5mm, a width of 85mm±5mm, and a height of 350mm±5mm. The corrosion resistance
of the metal surface is tested by acetic acid salt spray for 60 hours of continuous spraying, and the test result reaches 10 levels.

How to fixed

All connecting screws are carburized and hardened. The chair leg and the floor are firmly connected with Ø12mm explosive glue and
M8×60mm self-tapping thread. It is durable and has no shaking feeling. The surface snap-in PP rubber cover is embedded to prevent
dust and beautiful.

Production process and quality requirements

The main dimensions, wooden moisture content, appearance requirements, structural requirements, material requirements, physical
and chemical performance requirements, mechanical performance requirements and formaldehyde emissions of the seats are all in line
with the standards of "Cinema Theater Public Seats" (QB/T2602-2013). All metal surfaces of the seats are sandblasted to remove
rust, electrostatic sprayed, with strong adhesion, and the metal surface is corrosion-resistant. Acetic acid salt spray test
continuously sprays for 60 hours and the test result reaches 10 Grade, not easy to rust, good finish, beautiful and durable; all
welded joints are straight, firm, without welding defects, the welded joints are smoothly polished, the parts of the components
