Frequently asked by customers about the difference between an automatic three-roll gate and an electric three-roll gate.
In fact, the fully automatic three-roll gate is an electric three-roll gate, equipped with a motor, and the entire operation of the gate is driven by a motor. At the same time, when the power is turned on, the motor drives the brake lever to turn on the power automatically, which is very convenient to use.
The difference is the semi-automatic three-roll gate: equipped with a motor or two electromagnets to control the inbound and outbound locking and unlocking. After authorization passes, the electromagnet drives the unlocking arm to unlock, and the release lever can rotate in one direction, and the user can light Push the lever through the channel. The semi-automatic three-roll gate design anti-reverse function can effectively prevent pedestrians from retrograde.
Raw Material Of Epoxy Resin
Epoxy resin is a kind of high polymer, the molecular formula is (C11H12O3) N, refers to the molecule containing more than two epoxy groups of a polymer. It is a polycondensation product of epichlorohydrin and Bisphenol S or polyols. Because of the chemical activity of the epoxy group, it can be opened by a variety of compounds containing active hydrogen, cured and crosslinked to form a network structure, so it is a thermosetting resin. Bisphenol S epoxy resin is not only the largest yield, the most complete variety, and new modified varieties are still increasing, the quality is constantly improving.
