Security gate this equipment can be used in many places, last year's epidemic, but also to the security equipment industry has brought another spring, it should be noted that because of the shortage of security equipment, so there are many inferior security equipment on the market, under the guise of affordable offers to deceive consumers, warm tips, buy security equipment, be sure to choose a regular manufacturer, then, Should we pay attention to the selection of the shell material when selecting the security gate?

The material of door frame is one of the main indexes that affect the quality of door inspection. Because in the electromagnetic environment, the signal generated by the measured metal is very small, it needs to be amplified tens of thousands of times to meet the circuit drive requirements. If the displacement of the sensor changes, an alarm will be issued, so the smaller the deformation of the door shell of the inspection door, the better.

Generally, inspection doors are designed as separate door frames. The door panels are thin and long and are equipped with sensors. The thickness is only 5-6 cm, and the length can reach more than 220 cm. Due to long-term work and installation environment, the door panel is easy to deform, making the parameters of the sensor and the parameters of the factory very different, affecting the detection effect, can not carry out long-term work.

At present, the shell of the inspection door produced by most domestic manufacturers is made of high-density wood fiber board material or wood bran board. As we all know, high-density wood fiber board or wood bran board is easy to absorb moisture and get damp. After a few months of use, it will deform, disperse, etc. Especially in coastal areas, because the air is humid and the rainy season is long, the security gate can not be used for a long time. Good security door manufacturers should pay attention to this. The shell can be made of high-strength polyvinyl chloride material, and the door frame is made of aluminum alloy. This kind of material will not be damp, not easy to deformation, can ensure long-term normal use, no maintenance after ten years of use.
