How to distinguish the material of the stainless steel airport chair?

There are many types of stainless steel materials, so how to distinguish them when purchasing stainless steel airport chairs?

304 is a kind of universal stainless steel, which is widely used to make equipment and parts that require good comprehensive performance (corrosion resistance and formability).

301 stainless steel shows obvious work hardening when deformed, and is used in various occasions requiring relatively high strength.

302 stainless steel is essentially a variant of 304 stainless steel with higher carbon content, which can be made to obtain higher strength through cold rolling.

302B is a kind of stainless steel with relatively high silicon content, which has relatively high resistance to high temperature oxidation.

303 and 303SE are free-cutting stainless steels containing sulfur and selenium respectively, which are used in occasions that require free cutting and high surface finish.

304L is a variant of 304 stainless steel with relatively low carbon content, and is used where welding is required. The lower carbon content minimizes the precipitation of carbides in the heat-affected zone near the weld, and the precipitation of carbides may cause the stainless steel to be

The structure design of the seat plate and back plate of the airport chair:

1. The seat plate and the back plate are separated.

The armrest is reserved between the seat and the seat, which can be easily removed.

The seat plate and back plate material of the airport chair:

1. Material: back plate 19mm; seat plate 27mm thick and high-density polyurethane (PU) (internal steel frame, steel frame standard: steel tube Q235, diameter 16mm, thickness 2.0~3.0mm) mold forming.

2. It has good elasticity, the material is tightly combined, and frequent use will not cause deformation, wrinkling, breakage, or breakage

3. Backplane performance index

Density: (ISO845:1995) 360/M3.

Load: (ISO2439:2000)330N/.

Tensile strength: (ISO1798:2000) 2400Kpa.

Elasticity: (ISO8307)MM=41%.

Degree of tearing: (ISO8067) 1710N/M.

4. The performance index of the seat plate Density: (ISO845:1995) 380/. Load: (ISO2439:2000) 350N. Tensile strength: (ISO1798:2000) 2600Kpa. Elasticity: (ISO8307) MM=42%. Degree of tearing:

How to judge whether the row chair is genuine leather

1. Definition and classification of leather:

    The so-called dermis is a material that is chemically resistant, not easy to rot, and not easy to damage after a series of physical machines and chemical treatments are carried out on the peeled skin of the plant.

Natural leather is divided into: pigskin, cowhide, sheepskin, crocodile skin, ostrich skin and so on.

According to the rules, it is divided into: first layer leather and second layer leather. The so-called scalp skin is processed from the skin of inferior materials with less disability. The second-layer leather is made by using a peeling machine to make the first layer of jade into a grain, and then finish it.

2. Storage of conference chair leather:

    The auditorium chair seat has the function of ventilation, leaving a novel atmosphere from the small holes in the auditorium chair seat cushion and backrest, avoiding sweating on the hip and back area, and providing a warm ride. In fact, leather is the same. It must be placed in a cool and ventilated environment, so that the leather will not be moldy due to moisture absorption and avoid insects and rat bites.

3. How to distinguish genuine leather:

    One look: There are very clear pores and skin patterns on the leather, which are not available in synthetic leather;

    Second touch: The feel of the leather is soft, elastic, smooth and not coarse;

    Three smells: Genuine leather has a natural leather scent, while natural leather has a strong irritating smell, which is harmful to the human body

Waiting chair black matt or bright is better

It is difficult to judge which color of the waiting chair is good, because everyone has different aesthetics, the layout and characteristics of each venue are different, so it is impossible to compare which color is good, only the material and the same design are the best The waiting chair is out.

Standard color:

Black, blue, red, purple, green, silver gray, matt gray.
