With the increasing popularity of network digital surveillance, POE power supply is gradually familiar to everyone. Perhaps you have also used POE power supply to install network cameras or wireless engineering coverage, but you have not noticed it.
To understand POE power supply, you must first know its full name: Power Over Ethernet.

In our own language, POE power supply refers to the technology of providing DC power supply in this device while transmitting data signals for IP terminals in Ethernet. More generally, a network cable transmits both data and power.
The times are developing, the technology is improving, and the overall advantages of POE power supply are still many. Let's take a look at POE power supply and its advantages!
advantage:
1, flexible wiring: the previously considered power supply socket will not be too far to reach, now do not need to pay attention. Now the device location of the terminal can be flexibly installed to the remote location where you want to install, without restrictions.
2, cost savings: First of all, the power cord is reduced, and at the same time the power cord's supporting equipment will also be saved, sockets, pipes, transformers and so on. In addition, the time cost, labor cost, and maintenance cost of the power wiring in the integrated wiring are saved.
3, safe and reliable: can be centralized power supply such backup is very convenient, you can also connect the power supply equipment to the UPS, so once the power input is interrupted, you can also use UPS to ensure the normal operation of the system. ?
Typical application of POE switches:

PVC RESIN SG8

In terms of building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, and fibers, PVC was the world`s largest production of general-purpose plastics, and its applications are very widely. Widely used in all aspects

PVC is a white powder with an amorphous structure. The degree of branching is relatively small. The relative density is about 1.4. The glass transition temperature is 77~90°C. It begins to decompose at about 170°C. It has poor stability to light and heat. After prolonged exposure to sunlight, it will decompose to produce hydrogen chloride, and further automatically catalyze the decomposition, causing discoloration, and the physical and mechanical properties also rapidly decline. In actual applications, stabilizers must be added to improve the stability of heat and light.

The production process of PVC Resin SG8 and PVC RESIN SG5 is basically the same, and the production equipment is exactly the same. The main difference lies in the formulation of additives, polymerization temperature, reaction pressure and so on. The reaction temperature and reaction pressure of SG-8 resin have basically reached the working pressure limit of the polymerizer. The reaction requirements are relatively strict, and the requirements on operation, safety, technology, and personnel quality are more stringent, and the resin quality is more difficult to control.
