Why are acoustic magnetic security doors better than radio frequency ones?

• Why are supermarket security doors with acoustic magnetic systems better than those with radio frequency systems? What is the reason?
• Answer: This is because the acoustic magnetic system uses ultra-low frequency technology, which is not easily affected by environmental interference.
• In addition, the detection performance has also been improved.
• Therefore, the acoustic magnetic security door has greatly improved in anti-interference ability, equipment workmanship, and performance.
• It is a high-end product, so it is much more expensive than the radio frequency system's anti-theft device.

What is the difference between fully automatic three-roller gate, semi-automatic three-roller gate and manual three-roller gate?

• The fully automatic three-roller gate is actually an electric three-roller gate, but it is called differently. The fully automatic three-roller gate is equipped with a motor, and all operations of the gate are driven by the motor. At the same time, when the power is on, the motor drives the gate rod to rotate, realizing automatic pole-up when the power is on, which is very convenient to use.
• After the fully automatic three-roller gate is swiped, the gate rod will automatically rotate forward at an angle of about 5 degrees, and then, after the gate rod is gently touched with the body, the gate rod will automatically rotate and reset. This is because the fully automatic three-roller gate is driven by a motor inside, while the ordinary three-roller gate is reset by the solenoid valve, but not driven.

• The difference is the semi-automatic three-roller gate: the semi-automatic three-roller gate is an upgraded product of the manual three-roller gate, equipped with a motor or two electromagnets to control the locking and unlocking of the inbound and outbound directions. After the passage is authorized, the movement positioning arm opens, and the hand pushes the gate rod to rotate 120°, the electromagnet drives the unlocking arm to unlock, and the gate rod can be released to rotate in one direction, and the user can gently push the gate rod to pass through the passage. When the authorization is not passed, the authorization for illegal intrusion is cancelled within the specified time, the gate bar blocks the passage, and the power is cut off and the bar automatically drops, which can effectively prevent pedestrians from going in the opposite direction.
• Semi-automatic three-roller gate is a three-roller gate in the ordinary sense: after swiping the card, the person pushes the gate bar forward and passes with his body.
• Manual three-roller gate is a purely mechanical three-roller gate, without any electrical equipment, controlling free passage in one direction, only one-way entry or one-way exit, and the other direction is locked and prohibited from passing, and single-machine two-way control cannot be achieved, and there is no need to swipe the card, and the automatic positioning and reset system. When passing, the user only needs to gently push the gate bar with his hand to pass, and the structure is simple.

• Extended-arm barriers are a specially designed type of barrier with longer arm lengths compared to standard arm barriers. This design is typically used in situations that require wider passages or more stringent management of vehicle traffic.
• Here are some key features and possible specifications of extended-arm barriers:

1. **Arm Length**: The arm length of an extended-arm barrier is longer than that of a standard barrier, providing a wider passage suitable for large vehicles or special requirements. 2. **Material**: The arms are usually made of durable materials such as stainless steel, aluminum alloy, or special plastics to ensure strength and durability. 3. **Drive Method**: Extended-arm barriers can be driven by hydraulic, electric, or pneumatic systems to achieve smooth and stable arm movement. 4. **Control Method**: The control of the barrier can be manual or automated through remote control, ticketing systems, or computer software. 5. **Safety Features**: Extended-arm barriers may be equipped with safety sensors or infrared detection devices to prevent closure when there are vehicles or pedestrians under the arm, thereby enhancing safety. 6. **Weather Resistance**: As extended-arm barriers may be used in outdoor environments, they are usually designed with good weather resistance to withstand various weather conditions. 7. **Stability**: Due to the longer arm length, extended-arm barriers require stronger stability design to prevent deviation or damage under the influence of strong winds or other external forces. 8. **Maintenance**: Extended-arm barriers may require more frequent maintenance to ensure long-term stable operation, including regular inspections and lubrication of moving parts. 9. **Customization Options**: Depending on the specific application needs, extended-arm barriers may offer customization options, such as different colors, logos, or additional safety features. 10. **Installation Requirements**: Due to their size and weight, the installation of extended-arm barriers may require special foundations and support structures. 11. **Compatibility**: Extended-arm barriers should be compatible with existing security and monitoring systems to achieve unified management and control. Extended-arm barriers are suitable for controlling the passage of large or special vehicles in places such as industrial parks, large parking lots, and freight terminals. When selecting and installing, factors such as size, load capacity, safety features, and compatibility should be considered.

What problems should be paid attention to during the use of mobile houses?

• 1. Heat insulation of container mobile houses Container mobile houses are developing rapidly, and more and more people are using them. However, in the hot summer, people are facing such a problem, that is, the temperature inside the container mobile house is too high and cannot be insulated. Even if air conditioners or cooling appliances are installed, if the container mobile house is not insulated, it will be very hot under the sun. So let's take a look at how to insulate the container mobile house. 1. Rock wool also has a certain heat insulation effect, and rock wool can be properly combined with container mobile houses. 2. When building container mobile houses, the thickness of the foam can be appropriately increased to play a good insulation role. 3. Use black steel plates, which contain polystyrene foam, and are processed into a new type of building material. Such materials have a high heat insulation effect.
• 2. Anti-corrosion treatment of container mobile houses 1. Hot-dip galvanizing: Hot-dip galvanizing has a high degree of industrialization, long durability, and stable quality. Therefore, it is widely used in outdoor steel structures that are severely corroded by the atmosphere and difficult to repair. In recent years, a large number of corrugated steel plates in light steel structure systems have appeared. Hot-dip galvanizing is also widely used for corrosion protection. The first step of hot-dip galvanizing is pickling and rust removal, followed by cleaning. Incompleteness of these two steps will leave hidden dangers for corrosion protection, so they must be handled thoroughly. For steel structure designers, they should avoid designing components with mating surfaces to avoid incomplete pickling or incomplete acid washing in the gaps of the mating surfaces, causing the phenomenon of yellow water flowing on the galvanized surface. Hot-dip galvanizing is carried out at high temperatures. 2. Coating method: High-quality coatings rely on thorough rust removal. Commonly used fluorocarbon coatings have an anti-corrosion life of up to 50 years. Therefore, they are more used for indoor steel structures or relatively easy-to-maintain outdoor steel structures. It has a low one-time cost, but the maintenance cost is high when used outdoors. The first step of the coating method is rust removal. Therefore, high-requirement coatings generally use sandblasting and shot blasting to remove rust, reveal the luster of the metal, and remove all rust and oil stains. The coating constructed on site can be rust-removed manually. The choice of coating should take into account the surrounding environment, and different coatings have different tolerances to different corrosion conditions. The coating construction should have appropriate temperature and humidity, the construction environment of the coating should be less dusty, and there should be no condensation on the surface of the components. Do not get wet in the rain within 4 hours after painting, and the coating is generally applied 4 or 5 times. At the seaside or at sea or in a highly corrosive atmosphere, the total thickness of the dry paint film can be thickened.
• 3. Pay attention to fire prevention in container mobile houses When purchasing, pay attention to choosing mobile houses with rock wool boards as insulation materials, rather than foam color steel plates, which are very easy to cause fires. Other fire prevention precautions are: electric welding construction should be kept away from walls; heating equipment should be equipped with fire prevention devices in winter; it is strictly forbidden to use blowtorches on house materials; when laying lines, use refractory pipes.

Container manufacturers share some tips on cleaning containers

• When we use containers, we usually use them on ships, ports, routes, roads, transfer stations, bridges, and tunnels. Friends who use them frequently should know that the environment in such places is not particularly clean. How should we clean the dirty containers? The editor summarizes three methods for everyone. The specific situation is as follows:
• 1. Steam cleaning method During its operation, attention should be paid to the protection against high temperature damage. This method is suitable for containers that require high temperature degreasing, deodorization, and disinfection.
• 2. Manual and mechanical cleaning methods When choosing manual and mechanical cleaning, it is necessary to determine the degree of harm to the staff caused by the goods loaded in the container, and also to protect the box body. This method may cause some damage to the box body, so it should be used as little as possible or not at all.
• 3. Chemical cleaning method The operating environment of chemical cleaning is relatively dangerous in the container cleaning method, so before the operation, the operator's safety protection, on-site protection, environmental protection, etc. should be done, and the operation should be strictly in accordance with the specifications.
