High speed shutter door is a rapid operating, anti-crash shutter door for indoor application . The most advantage of this door is that the opening/closing speed can reach to 0.6-1.8m/s, really fast action a lot than tranditional rollling shutter door. short opening and closing times reduce cooling loss, avoid airflow and enable a smooth operating procedure. They can also be designed in larger dimensions for the mining and aircraft industries.
High speed door can be easily installed, economical,quiet and efficient with electromechanical drive.
This door quickly though in/out open gate, ideal for warehouses,factories, hangars use, widths can be from 2m to 20 meters.
The material of this door are variety: PVC curtain to keep the insdie clean, heavy duty aluminum door with wind-resisitant function can wrok in heavy windy weather, and also the freezer door can be used in cold warehouse or somewhere like that.
Including models are:PVC High Speed Door, Aluminum Spiral High Speed Door, Self-Recovery repair door, Cold Storage Room Fast Door.

Superhard material surface plating technology and application
Abstract This paper systematically discusses the interfacial reaction, interface structure and interface bonding of all-gangue and cubic boron nitride superabrasives with typical metal interfaces. According to the interface between metal and diamond, the typical metal is: an affinity metal that reacts with the diamond interface to form a stable carbide, such as titanium, tungsten, chromium, molybdenum, etc.; an inert metal that does not react with the diamond interface, such as copper. A graphitized genus that contacts the diamond interface to promote diamond graphitization, such as iron, cobalt, nickel, and the like. The relationship between the affinity metal and the superabrasive interface to form the compound and the relationship between the structural characteristics of the chemical and the interfacial bonding strength are discussed, and the conditions for the strong bonding of the affinity metal to the diamond are given. Based on these theoretical results, the characteristics and application effects of various plating methods are explained.
