FAQ

Recommend to you the purchase of industrial doors：

There are many types of industrial anti-collision doors. There are many types of anti-collision door products on the market. First of all, we must figure out the composition and internal filling classification of anti-collision doors so that we can distinguish the difference between quality and design and the difference in price when purchasing. The types of internal filling of industrial anti-collision door products can include the following. According to the material, they are divided into wood panels with the core, polyurethane foam with the core, plastic with the core, and aluminum honeycomb with the core. The sandwich is made of aviation aluminum with waterproof and soundproof treatment, and the aviation aluminum plate sandwiched inside the anti-collision door is currently a best-selling type on the market. Anti-collision doors with a good reputation have done a better job in the internal structure treatment process, so that the molded door body does not deform or crack, and has a long life span.

The cost of anti-collision doors is high and the price is high. If the internal structure is not properly treated, the door body of the anti-collision free door is easy to deform, the tenon joints crack, and the door core shrinks and corrodes the surface. Therefore, the industrial anti-collision doors filled with aviation aluminum plates in the door industry all avoid the above problems. They are impact-resistant and have a relatively long service life. They are resistant to water and inflation, and do not rust. They have the characteristics of smooth feel and soft color. , Environmentally friendly, strong and durable. The performance is more stable, it has the characteristics of thermal insulation, impact resistance, flame retardant, etc., and the sound insulation effect is good. Generally, the flame-retardant properties of the internal filled wooden panels and other filled anti-collision doors are relatively poor. Compared with the anti-collision door of our aviation configuration, it has no obvious advantages in appearance and is not cost-effective. It is easy to corrode, and the sound insulation effect is not good, and it does not heat or keep warm. The disadvantage is that it is easy to bump. The free door adopts specially designed hinges and can be opened in both directions. Using the principle of eccentric shaft and the principle of self-weight reset, relying on the self-weight of the door, the door can be completely closed automatically after a person or vehicle passes through. Enable people or goods to pass faster and improve work efficiency. The characteristics of corrosion resistance, easy to clean and maintain, and long service life make it widely used in a variety of fields.

The types of industrial anti-collision doors, there are many types of anti-collision door products on the market, first of all, we must figure out the composition and internal filling classification of anti-collision doors, and only when purchasing can we distinguish the difference in quality and design, and the distinction of price. The types of internal filling of industrial anti-collision door products can include the following, which are divided into wood panels, polyurethane foam, plastics, and aluminum honeycombs according to the material. The sandwich is made of waterproof and soundproof treatment aviation aluminum, and the sandwich aviation aluminum plate inside the crash door is the best-selling type in the market. The anti-collision door with a good reputation has done a good job in the internal structure treatment, so that the formed door body is not deformed and cracked, and the service life is longer.

The cost of the anti-collision door is high, the price is high, if the internal structure is not properly treated, the door body of the anti-collision free door is easy to deform, the tenon joint is cracked, and the door core plate shrinks and corrodes the surface. Therefore, the industrial anti-collision door filled with aviation aluminum plate inside the door industry avoids the above problems, is impact-resistant and has a long service life, water-resistant, inflatable, no rust and other advantages, with the characteristics of smooth feel, soft color, environmental protection, sturdy and durable. The performance is more stable, with the characteristics of heat preservation, impact resistance, flame retardant, etc., and the sound insulation effect is good. However, the flame retardancy of the internal filling wood board and other filled anti-collision doors is relatively poor. Compared with our aviation configuration padded anti-collision door, it has no obvious advantages in appearance, and the cost performance is not high. It is easy to corrode, and the sound insulation effect is not good, and it is not heat insulated or insulated. The disadvantage is that it is easy to bump, and the free door is a specially designed hinge that can be opened in both directions. Using the principle of eccentric shaft and the principle of self-repeating position, the door can be completely closed automatically after the person or vehicle passes through by relying on the self-weight of the door. Enable people or goods to pass faster and improve work efficiency. Corrosion-resistant, easy to clean and maintain, and long service life make it widely used in a variety of fields.
3. According to the structure of the library

(1) Civil cold storage, which is currently built more than one kind of cold storage, can be built into a single or multi-storey. The main body of the building is generally a reinforced concrete frame structure or a brick-concrete structure. The civil cold storage enclosure structure is a heavy structure, the thermal inertia is larger, the outdoor air temperature fluctuates day and night and the outer surface of the enclosure structure is caused by solar radiation to cause diurnal temperature fluctuations, and the attenuation in the enclosure structure is larger, so the temperature fluctuation of the inner surface of the enclosure structure is small, and the storage temperature is easy to stabilize.

(2) Combined plate cold storage, this cold storage is a single-layer form, and the library plate is a steel frame lightweight prefabricated heat insulation board assembly structure, and its load-bearing components are mostly made of thin-walled steel. Since all components are prefabricated in professional factories according to unified standards and assembled on the construction site, except for the ground, the construction progress is fast and the construction period is short.

(3) Covering soil cold storage, it is also known as soil kiln cave cold storage, the cave body is mostly arched structure, there is a single cave type, there is also a continuous arch form. Generally, it is masonry masonry, and a certain thickness of loess overburden is used as an insulating layer. Used as a low-temperature soil covering cold storage, the foundation of the cave body should be located on the sand and gravel layer or bedrock that is not easy to frost heave. Because it has the advantages of adapting measures to local conditions, local materials, simple construction, low cost, sturdy and durable, etc., it has been more developed in the northwest of China.

(4) Cave cold storage, generally built in the stone is relatively hard, good integrity of the rock formation, the inner side of the cave is generally lined or spray anchor treatment, the thickness of the cave rock layer is generally not less than 20m.
