6) The batch authorization mode for personnel grouping can be realized. Personnel import can be imported without the need of non-format, reducing workload and improving efficiency.
7) The ladder control system can access floor and building entrance authority according to authority, and restrict unrelated personnel from entering floors that do not belong to the authority. Avoid the arbitrariness of building traffic and enter into disturbing normal office orders without reservations.
8) Support building security personnel to implement patrol management with a card. Any reader can be set as a patrol point, and no special patrol apparatus needs to be configured.
9) Support video linkage video capture and capture, customize the number of snap shots and the length of video clips, and uniquely save on the card platform server, which can be remotely viewed and supports the linkage function under alarm conditions. Report-style image management. Can effectively protect the company's property during non-working hours.
10) The electronic map's alarm mode, real-time display of alarm locations and viewing of live video switching, fire alarms, temperature and humidity detection, smoke detection, water intrusion detection and other alarm information. Support multiple alarm modes such as flood prevention and tamper protection, duress alarm, and multi-level alarm processing modes.
11) Basic function rights management and permission application scope, basic calendar calendar function, can be used for any infinite number of daily table combination applications. Personnel information is imported into the template without formatting. Report management mode 12) Car park management function to realize the management of entrance and exit of building vehicles.
13) The phone and SMS alarm mode can be implemented to protect the building during non-working hours, and the non-authorized personnel can be quickly and non-authorized to access the non-authorized area, and a multi-level closed-loop alarm processing mode can be realized to quickly handle related events.
14) The main control and sub-control mode can be used, which can save the engineering cost and maintenance cost of the intelligent building in view of the relatively centralized characteristics of the gates in the building.
15) Due to the special features and application security of the intelligent building, dual controller hot backup mode can be used. In the event of a controller failure, the backup controller can seamlessly connect to ensure the continuous application of the entire system. Improve the overall safety of the building.
16) Lighting control of the building floor and air-conditioning credit card control can save energy.
17) Provide a standard OPC interface, which can be easily connected to the IBMS management platform of the Intelligent Building to achieve the overall control of the building.
PEI plastics (polyetherimide plastics) is an amber transparent solid. It has an inherent flame retardancy and low smoke concentration without adding any additives. The oxygen index is 47%, and the combustion level is ul94-v-0, and the density is 1.28~1.42 g/cm3.
PEI plastics has a strong thermal stability, and even the non-enhanced PEI plastics still has good toughness and strength.Therefore, the high thermal stability of PEI plasticsis used to make high temperature heat-resistant devices.
PEI plastics has excellent mechanical properties, electrical insulation performance, radiation resistance, high temperature resistance and abrasion resistance, and can be used by microwave.The PEI plastics also has good flame retardancy, chemical resistance and electrical insulation.Vitrification transformation temperature is very high, up to 215 ℃.PEI plastics also has a very low shrinkage rate and good mechanical properties.Adding fiberglass, carbon fiber or other fillings to enhance the purpose of modification;And other engineering plastics of heat-resistant polymer alloys, can be in 160 ~ 180 ℃ under the working temperature of use for a long time.
The long-term use of polyether amines in the us underwriters laboratory is 338T and 356T (according to the grade), and the combustion rating reaches UL94V - 0 (10 mille thickness).The oxygen index is 47, and the polyetherimide is in line with the requirements of the aircraft for the requirements of the FAA's flame retardant and thermal release material standards.It has a glass transition temperature of 419F and is allowed to be used intermittently under 392F, at higher temperatures, resulting in a short-term shift.Under 356T, the tensile temperature and flexural modulus were above 41 and 2068MPa respectively.The material reinforced with Glass Fiber and carbon fiber has higher strength and rigidity under the transition temperature of glass.
PEI plastics long-term resistance to creep under high temperature and stress allows it to replace metals and other materials in many structural devices.PEI plastics shows good performance in variable temperature, humidity and frequency.The low dissipation factor at GHz frequency makes the polyetherimide have high microwave wearability.Its ionic pollutant is low, at 250F100 % R.H.And 207kPa after 120 hours of water extraction with the conductivity, at 20 megaohm, it can be used as an electronic sensor element insulation.
PEI plastics is a fine coating and film forming material which can be used for the coating and film of electronic industry, and can be used in manufacturing aperture < 0.1 mu m, with high permeability microporous diaphragm.It can also be used as high temperature adhesive and high strength fiber.
Application field
Since PEI plastics has excellent comprehensive and balanced performance, PEI plastics has been applied to the departments of electronics, motor and aviation, and used as metal substitute materials for traditional products and cultural life supplies.Using PEI plastics instead of metal to make optical fiber connector, PEI plastics can optimize the structure of the component, simplify its manufacturing and assembly steps, and maintain a more precise size.Used in automobile industry, such as high temperature fittings for manufacturing, the high power lamp and light, control the car cabin outside temperature sensor (air conditioning temperature sensor) and the control of air and fuel mixture temperature sensor (effective combustion temperature sensor).Also can be used for high temperature erosion of lubricating oil vacuum pump impeller, distilling apparatus that operate at 180 ℃ of ground glass joints (following), the lighting of anti fog light reflector.
