Safety work is serious. Those bloody cases of safety accidents always remind us of the importance and urgency of safety, and also remind us that this is a battlefield without gunpowder smoke. Let's carry out and implement all kinds of work in a down-to-earth manner, without missing a detail or leaving a hidden danger, so as to put the hidden danger at the source.

2. What are the similarities between fast rolling shutter door and ordinary rolling shutter door? When it comes to the similarities between the two, the big thing may be that their materials are the same; the door frames are all made of aluminum alloy. Of course, in addition to the similar materials used for the doors, there is no big difference in the modeling industry. The color of the curtain can also be selected according to the consumers' preference.
High quality rolling shutter door has the following elements: control system, rolling shutter door piece, auxiliary materials, and more important installation process!!! First of all, the most important part is the control system, which is also the part of motor and remote control or switch. Because of the different requirements of frequency and environment, the single air shower room has different emphasis on service life, noise, safety and control. Therefore, the control system is very important! Secondly, the performance of the curtain is also very important. Basically, the roller shutter materials used in the market include aluminum alloy (thermal insulation polyurethane foam), galvanized steel strip (also has foam), aluminum profile (hollow), etc.; the thickness of the tape is 0. 2-0。 The surface treatment includes baking paint, zinc plating, epoxy resin back coating, and fluorocarbon, etc.; the foam material is basically fluorine-free polyurethane. The material of rolling shutter door directly affects the performance of rolling shutter door, such as thermal insulation, sound insulation, weather resistance and strength.
The power-off ground lock of wind resistant rolling shutter door is more prominent than the existing technology, and the beneficial technical effects are as follows: 1. Through the signal controller to control the power supply state of the wind resistant rolling shutter door motor power socket, and then control the applicable state of the rolling shutter door motor. The installation of the electric rolling shutter door manufacturer can avoid the damage caused by remote starting the rolling shutter door when the ground lock is not opened. The material of rolling shutter door directly affects the performance of rolling shutter door, such as thermal insulation, sound insulation, weather resistance and strength. PVC characteristics and molding characteristics specific gravity: 1. 38 g / cm3, forming shrinkage: 0. 6-1。 5%, molding temperature: 160-190 ℃. 1、 High speed rolling shutter door is also what we often call high-speed door and fast rolling shutter door. It has many functions, such as heat preservation, cold insulation, insect prevention, wind protection, dust prevention, sound insulation, fire prevention, odor prevention, daylighting, etc. The fire resistance performance of fire shutter door is from the time when the heat radiation intensity of the back fire surface exceeds the critical value, or when there is fire on the curtain panel surface.
Workers are not allowed to stop at the port without permission. In case of special circumstances, the port crane operator on duty hears the safety alarm bell, connects with the upper and lower personnel, stops the port crane to a safe position, opens the port crane safety door, and closes the safety door when the personnel leave.
Radar is equivalent to the eyes of PVC high-speed door. It is mainly used to detect whether there are moving objects. When it is detected, the fast door will open automatically and close automatically after reaching a certain delay time.
4. The operation mode of the self fast shutter door in the air shower room can be divided into: manual button operation, remote control operation, geomagnetic induction, radar induction, IC / ID card swiping, automatic opening and intermittent closing function, and self-contained servo frequency conversion function, which is suitable for factory, sealed space, food processing room and electronic processing room.
3. What's the difference between fast rolling shutter door and ordinary rolling shutter door? If you want to mention their differences, of course, their working principles are different. Ordinary rolling shutter doors can only close and open the door manually. However, fast rolling shutter doors can only be operated by remote control. They can complete themselves in a short time without too much noise. Of course, after power failure, they must be the same as ordinary rolling shutter doors, Moving door company manual operation.

Recently, the blast furnace raw material maintenance team of the second sintering plant has made protective safety doors for 26 port cranes in the port crane section to avoid unnecessary accidents caused by non port crane personnel entering the operation area.
A fast rolling shutter door needs many accessories. Although these accessories seem insignificant, they play an important role in the operation of PVC fast door. It has four buttons to open, close, stop and lock. The receiving end is directly connected with the main control box. In the range of 10 meters from the door body, the remote control can be used for operation, and once it happens, it can be operated by remote control In case of emergency, press the stop key to stop the PVC fast door at any position.
What is a fast rolling shutter door? It is a kind of electric rolling shutter door, and its running speed is more than 0 per second. It can open and close the door quickly to a large extent without manual operation. It only needs to see the command line. The air shower room can provide convenience for users to a large extent, and can greatly reduce the noise generated by opening and closing the door.
