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.

There are many kinds of desk and chair sets on the market, the price difference is large, and the quality is also uneven. If you choose cheap ones, the quality cannot be guaranteed. There are many factors that affect the quality. If you want to buy good quality products , we must first understand the factors that affect the quality of desk and chair sets.

Process factors affecting the quality of desk and chair sets

1. Welding wheel diameter

The diameter of the welding wheel determines the diameter of the nugget. As the new welding wheel is ground again and again, the diameter gradually becomes smaller, the contact area between the desk and chair and the steel strip is reduced, the current density is increased, and the pressure on the welding point is increased. Also added, so the diameter of the welding wheel cannot be too small.

2. Welding current

The influence of the welding current of desks and chairs on the heat is a quadratic relationship. As an adjustable parameter, it can be selected according to the thickness of the welded steel strip. The factors that affect the actual current change are the fluctuation of the power supply voltage and the resistance of the secondary circuit. In order to ensure that desks and chairs are not affected by external conditions, it is necessary to adopt a constant current control system.

3. Welding time

The welding heat of desks and chairs is proportional to the welding time, but the power-on time is controlled by the speed of the welding wheel. Generally, no adjustment is required. Even if the adjustment is made, only small-scale adjustments are required.

4. Touch resistance

The biggest influence on the occurrence and spread of heat is the resistance of the touch surface of the steel belt. The main factors affecting the touch resistance are the cleanliness and roughness of the touch surface. If the touch surface of desks and chairs has oxides or dirt with high resistivity layer, which will add resistance, and if only part of the dirt or oxide is present, will make the current spread unevenly, so the touch surface needs to be kept clean and tidy. If the touch surface is rough and uneven, the desks and chairs will form part of the touch point, and a large current will occur at the touch point, and the touch resistance will increase due to the reduction of the current channel.

2. Factors affecting the quality of desks and chairs

1. Deliberate destruction: Deliberately destroying, stepping on desks and chairs, hitting desks and chairs with hard objects, or carving on desks and chairs with sharp objects, even the best quality desks and chairs are easily damaged, resulting in deformation or falling apart. directly affect the shortening of its service life.

2. Improper maintenance: If you encounter strong corrosive detergents, the tables and chairs will be corroded. After a long time, the tables and chairs or the main frame will rust. Rust will cause the material to become thinner and directly affect the product quality.

3. Inadequate cleaning: If it is not cleaned for a long time during use, it will cause residual oil on the desk. If it is not cleaned regularly, it will cause the desktop to be corroded.

4. Pulling and pulling: Sometimes the school needs to carry or move the desks and chairs for activities. When moving, the desks and chairs must be lifted and moved.

The above is the entire content of the process factors and use factors that affect its quality. The process factors include welding wheel diameter, welding current, welding time, touch resistance, etc., and the use factors include deliberate destruction, improper maintenance, and inadequate cleaning. Pull hard and so on.

The use of school desks and chairs will have a greater impact on schools and students, so there are many aspects that need to be paid attention to when configuring desks and chairs. So how to correctly choose school desks and chairs manufacturers?

How to choose the school desk and chair manufacturer correctly

1. First of all, before we choose the school desk and chair manufacturer, we can conduct a systematic inquiry on the manufacturer on the Internet, so that we can have a certain basic understanding of the manufacturer, but we need to pay attention to not blindly believe that its online Because they are basically beautified, they are not necessarily true. Therefore, after having a basic understanding, you can conduct on-the-spot inspections in several favorite manufacturers, so that you can see more intuitively. The strength of the manufacturer.

2. Then we can observe more about the scale of the manufacturer during the on-site inspection, such as its production equipment, technicians and processes, etc. Generally, manufacturers with sufficient strength are relatively complete as a whole, and their requirements are relatively high. Therefore, from these aspects, it can be seen whether the manufacturers of school desks and chairs are good or not, so that the selected products can be guaranteed enough and avoid unnecessary hidden dangers and troubles to themselves.

3. Because desks and chairs are used more frequently, and the users are mainly students, but the school’s procurement itself also has certain restrictions, so the quality of school desks and chairs is more valued by everyone, so school classes Table and chair manufacturers must ensure that their quality is good enough, but some damage will inevitably occur after a period of use, so its after-sales is very important, so when choosing a manufacturer, pay attention to whether it can provide good after-sales.

Several tips for purchasing school desks and chairs

1. The color of school desks and chairs should not be too bright

When choosing school desks and chairs, many people think that they should choose brighter and more active colors, or choose a lot of cartoon patterns according to children’s preferences, etc. They feel that bright and bright colors help children form optimistic and lively characters. . However, some agency tests have shown that the brighter the paint color, the more heavy metals such as lead it contains. This is mainly caused by the lead compounds contained in the paint pigment, so the brightly colored school furniture has a much higher content of harmful substances than ordinary ones. Therefore, when purchasing desks and chairs, remember to ask the manufacturer for the school furniture paint inspection report to check whether the desks and chairs are qualified.

2. School desks and chairs with environmentally friendly materials should be selected

The wood material maintains the original color of the wood, which is natural and rustic, environmentally friendly and healthy, and most of them belong to good school furniture. Most of the non-wood materials are synthetic materials with fashionable appearance and low price. However, due to the application of some chemical materials in the material synthesis process, they have hidden dangers of environmental protection. It is recommended that consumers choose natural wooden school furniture or some well-known brands of non-wood desks and chairs as much as possible when choosing.

3. Be careful to buy the material of the metal edge

Many desks and chairs are decorated with shiny aluminum edges, but most of the metal edges are sharp, and children are likely to scratch their hands when they touch them. Now more and more plastic edges are used. And some of the metal that acts as a support for the frame, the sharp corners are installed inward to minimize the possibility of children touching. Like screws may also have sharp metal edges, which requires special hardware fasteners to cover sharp screws in classroom furniture.

4. Choose less furniture made of glass

Generally speaking, desks and chairs are not suitable for use of ordinary glass materials, because the glass is fragile, and the sharp edges and corners formed after shattering can easily cause injury. If you want to use transparent materials for reasons such as aesthetics, the designer recommends using tempered glass or organic sheets instead.

The above is the introduction of how to correctly choose the school desk and chair manufacturer and the skills of purchasing desks and chairs. I hope it can be helpful to everyone. Whether it is choosing a manufacturer or a desk and chair, you can choose the right one.

The use of student desks and chairs in schools is very common, because if the school does not have student desks and chairs, students cannot carry out normal learning, and the study desk is very important, so the school is choosing student classes.

Students’ classroom teaching is an important part of students’ receiving systematic education. With the continuous improvement of living standards, students’ physical development is getting better and better, but the desks and chairs used in many schools are still designed according to the height ratio of previous students. Height and width will be somewhat inappropriate.

If students study on such desks for a long time, they will often form bad postures, which will not only affect the quality of students’ learning, but also be detrimental to the cervical spine and spine. So, how should we choose the desks and chairs for students correctly?

How to choose student desks and chairs

1. Purchase according to the student’s height and size

The height of desks and chairs and the height of the human body cooperate with each other, which can adjust the sitting posture. Among all types, lift desks and chairs are more suitable. We all know that children’s bodies grow rapidly. If the desks and chairs are not properly selected, Then it will not be suitable for a long time, and it will not be able to be used again after a year or two. Therefore, it is better to choose a lift desk and chair. Lifting student desks and chairs can not only lift the chair, but also the table, which is more convenient and practical. The desk top adopts multi-angle adjustment components, which can be adjusted to the angle suitable for students to read and write.
