How to identify the quality of auditorium chairs?
There are many auditorium chairs and cinema chairs in the market, and people are dazzled at the exhibition, and there is no way to start when choosing. What are the specific styles of auditorium chairs and theater chairs? For those who don’t understand, they are the same except for the appearance. They don’t know how to identify the quality and where to choose. In fact, auditorium chairs and cinema chairs are classified from bottom to top. Looking down at the feet, auditorium chair tripods can be divided into aluminum alloy feet and iron feet.
Aluminum alloy feet: The aluminum alloy feet are made of aluminum alloy materials, which are light in weight and are not easy to corrode in a humid environment; they will not deform or crack in a high temperature environment; the service life is relatively long, which can meet the different needs of customers (bending or pulling straight).
Iron feet: The iron feet are hard, heavy, and brittle. The surface is electroplated and easy to rust.
Looking at the seat back outer panel, the outer panel is divided into paint panel and plastic shell.
Painted board: The high-quality multi-layer board is cold-pressed by a mold and painted to prevent cracking effectively.
Plastic shell model: The plastic back shell is made of high-quality PP (polypropylene) multi-element conforming material and is molded by injection molding, with a thickness of 3mm. The seat rubber shell is made of high-quality PP (polypropylene) multi-element conforming material by injection molding, with a thickness of 4-6mm. With a muffler hole, it can effectively remove ambient noise.
According to the above description, auditorium chairs can be roughly divided into 4 categories: aluminum alloy paint models, aluminum alloy plastic shell models, iron foot paint models, and iron foot plastic shell models.
We have a certain understanding of the types of auditorium chairs through the above, but after all, professional people are in the minority, how to distinguish the quality of auditorium chairs?
First, heating method: negotiate with the manufacturer for a small piece of leather or fabric, touch the leather or fabric with a cigarette butt for 3 seconds, and observe whether it is flame retardant. This avoids buying defective products.
Second, the certificate law: the leather and fabric used by regular manufacturers have a clear source, production place, trademark, leather test form, authorization letter and other basic information, you can check it, these certificates are indispensable.
Third, the wiping method: if the leather is used, you can wipe the surface of the leather with stain remover oil, and pay attention to whether there is fading and falling off, so as to avoid buying 2 color-changing leather.
Fourth, olfactory method: good leather and fabrics will not have a pungent smell after processing. If the smell is too large, then the quality of the auditorium chair can be considered.
Fifth, labeling method: the leather used by regular manufacturers will be marked with the date of manufacture, the name and area of the leather factory, etc. on the back. (The date of manufacture should not be too long, and if the leather is more than 3 years old, you should pay attention to whether there is mildew).
Sixth, the observation method: for the leather auditorium chair, the observation method can be used. Under a 30 times magnifying glass, it can be seen that there are obvious pores on the surface of the leather, which has the characteristics of the original skin, so the air permeability is good. After cutting the leather with a blade, it can be seen that the color of the leather from the outer layer to the inner layer must be the same.
Pay attention to whether there is a different color under the outer layer, and avoid buying second-hand leather that has been dyed or changed color. For fabric auditorium chairs, you can wipe it back and forth with your hands to see if it is pilling and whether there is a hook line.
