Development of the patrol system

Electronic patrol systems are marginalized products, whether they are security products or office products. They are not very mainstream, but at the same time they are indispensable. Everyone may have seen it in their own community. A security guard is holding a patrol and patrolling the community. This is very close to everyone's life and gives the user a very personal feeling. The significance of electronic patrol products is more of a regulatory role. Regulatory patrol personnel are patrolling as required, strictly speaking, products that are separated from security products. In recent years, electronic patrol equipment has introduced some applications of biometrics, remote monitoring and other technologies.

The traditional patrol can tell the manager who has been there at what time. The current inspection requirements require not only the information indicated by the feedback, but also the problems found in the inspection. Whether the inspection information is returned in real time, can the problem be reflected immediately? Etc., are also required for today's devices. Therefore, the main difference between the new product and the previous product is also the improvement of the real-time nature of the product. After all, for the new system, when it is out of the access control system, the advantage is that it can pay attention to the position of the patrol personnel in real time. After reading the card, the information will immediately return to the management center, and the manager will immediately see it. For traditional equipment, it is difficult to install, requires wiring, and is also affected by the environment and distance in transmission, resulting in a relatively narrow application field.

Later, domestic and foreign companies gradually abandoned the way of wiring patrols, using offline patrols, which can be unaffected by the surrounding environment, because this is a mobile acquisition, so no wiring is required. However, such a configuration also has its drawbacks: that is, the real-time nature of the online patrol cannot be completed--offline patrols must be patrolled after the patrol is completed, and then the leader can see the record and become an after-the-fact monitoring. This is undoubtedly difficult to accept for more important occasions, such as the more important departments of the military, public security, fire protection and armed police.

So in order to complete the real-time performance, we can apply the new technology of mobile network to the patrol technology through CDMA or GPRS, and integrate the information of wiring and offline patrol, which can be transmitted back in real time. This is also the new type. The biggest advantage of electronic patrol. Of course, the application of new equipment also puts higher demands on patrol personnel. For some technical vulnerabilities or defects, the controller should also be more sensitive. In order to achieve higher linkage of the system, the electronic patrol system has realized the combination with the access control system.

Metal Attenuated Agent

Introduction: This product is white crystal powder, soluble in methanol and acetone, sparingly soluble in chloroform and ethyl acetate, insoluble in water. The product can exit in two different crystal modification(melting point at 200 ℃ to 230℃).White or off-white powder,melting point 175-177℃,flashing point 206℃.kindling point 273℃,stabilization for heat. Solubility (g/100g solvent):Acetone 10g,Chloroform 35g, Hexane 0.03g, styrene 5g,water 0.01g.



Applications: This product possesses the double structures of hindered phenol and acyl, and a function of anti-oxidation and metal deactivation. This product is a kind of metal deactivator,can be used either independently or together with antioxidant. It is applicable to polyethylene, polypropylene,polystyrene,polyamide, polyester and especially to the antioxidant used in phenolic resin. It is effectively preventing the polymeric substance from self-oxidation caused by transition metalion(the remains of the catalyst).  It protects polymers against oxidative degradation and metal catalyzed degradation during processing and in end- use applications. This antioxidant also provides long term thermal stabilization properties. This phenolic antioxidant is an excellent,non-discoloring, non-staining antioxidant and thermal stabilizer with outstanding metal deactivation properties. This product has the characteristics of low volatility and no coloring of products.
