Chinese markets often have Chinese characteristics. When foreign products are emphasizing the security of access control, domestic users and integrators only emphasize convenience. From the application of the three-roller gate: because of the proximity of sensor cards or biometric-based identification, China is bound to develop intelligently. The prospect is “one card, one library, one platformâ€. This trend has gradually been accepted by the market.
The concept of the three-roller intelligent system was proposed. When the project was designed, a card was required to open the door, attendance, consumption, parking, patrol, elevator control and so on. The access card system is a small part of the Internet of Things. The Internet of Things contains a wide range, which poses a great challenge to the access control card system.
The ratio of high-end products and low-end products in the market is about 1:3, which puts high demands on the linkage, especially the linkage with TV monitoring, fire alarm and building automation system. It also highlights that the network provides convenience for software-based linkage, and only software linkage is more suitable for digitization and networking.
Biometrics will be favored by users, especially fingerprints, palms and face recognition. Multiple literacy techniques may also be required in the system being composed.
The three-roller intelligent system can also perform some functions of information release, such as displaying the weather conditions, welcome words and other information on the LCD screen of the card reader. Now with the development of automation, the system needs to be linked with fire alarms, linked with CCTV, effectively combined with BA system (building automation system), and effectively combined with information distribution system.
Tert-butyl Hydroperoxide
Tert-butyl Hydroperoxideis a hydroperoxide, in fact one of the most widely used in a variety of oxidation processes, for example the Halcon process.It is normally supplied as a 69–70% aqueous solution. Compared to hydrogen peroxide and organic peracids, tert-butyl hydroperoxide is less reactive and more soluble in organic solvents. Overall, it is renowned for the convenient handling properties of its solutions. Its solutions in organic solvents are highly stable.
Industrially, tert-butyl hydroperoxide is used to prepare propylene oxide. In the Halcon process, molybdenum-based catalysts are used for the reaction.
On a much smaller scale, tert-butyl hydroperoxide is used to produce some fine chemicals by the Sharpless epoxidation.
TBHP Is a volatile, yellowish liquid ,it is alkyl hydroperoxide initator for polymerization of acrylic emulsion ,and wiedely used as raw material for organic peroxides synthesis.
Miscible with organic solvents such as alcohols,esters,olefins and NAOH solution.Slightly miscible with water.
