The difference between security doors and security doors
The security door is very familiar with the word, indeed, we have seen the security gate, but many people do not know whether the security door is flawed, and even some people think that security is the security door, this statement right?
Most of the security gates are used at airports, subways, etc. as ticket gates. Now everyone knows that security doors are not security doors. With the progress of the ages, security gates are now widely used in high-end office buildings, libraries, theaters, factory companies, convention centers, stadiums, tourist attractions, etc. The intention is to provide a highly effective two-way controllable channel.
First, the security door has a ripple effect:
With the development of science, the variety of security gates is also diverse. It can be divided into: 1. Retractable speed-through doors (wing gates), characterized by its rapid, smooth single or two-way control of revenue and expenditure; Swing gate, it is a kind of pedestrian channel control equipment with a high degree of safety protection; 3, optical gates, mainly used to deal with income and expenditure flows and ID cards and planning monitoring and revenue control equipment; 4, three roller gate This is a line-limited revenue and expenditure control device that specifically handles visit control and personnel flow; 5, revolving doors, mainly designed for high-level security needs of the two-way high-speed channel control equipment, can be used for unmanned channels under supervision Handling; 6, Pingkai Men, mainly for the channel called the majority of the venue planning limit line channel control equipment.
Second, the difference between security doors and security doors:
The legal difference between security door and security door is that the first security door must have a permanent fixed symbol in the national standard's national standard directory. This symbol is used to determine the position of the hinge on the side of the inner hinge and the height of 160 cm from the ground. The anti-theft security level of the security door is indicated; the security door does not have the corresponding national standard.
Security doors and security doors in the difference in life, security doors are mostly used for home decoration, up to also used for the community's door, the effect is mainly anti-theft, sound insulation, etc.; and security doors, we all know that non-public places will not No one will use the security door at home.
Security doors and security doors, of course, also have a feature together, that is, to ensure everyone's safety, and therefore, from this point of view, security doors and security doors have a great effect on the safety of people.
(1)Tubing : CPVC is mainly used for processing tubing and hot water delivery and corrosion medium. It can keep enough strength if the temperature is less than 100℃ and can be used for long time under higher inner pressure. CPVC pipe can be used as hot sewage pipe, electroplating solution piping, thermochemistry agent transfer piping of enterprises and the wet chlorine transfer piping.
(2) Fitting : CPVC Resin can be used to produce the fittings of flow pipe, filtering material, and spin-drier etc, as well as electrical appliances and electronic parts such as wire way, conductor protective layer, electric switch, fuse closure door and insulation material of cable. etc.
(3) Corrugated board : the CPVC corrugated board has the natural corrosion resistance, resistance to high (low) temperature, heat insulation performance is excellent.
(4)Foaming material :The heat resistance of foaming material of CPVC is better than that of PVC. The shrinkage at high temperature is very small. It can be used as heat preservation material of heat water pipe and steam pipe and so on. The retentivity to solvent of CPVA with chlorine content more than 60% is very good. The CPVC can be put into the solvent for foaming which can produce the gas while heated, and you can get the homogeneous and minor forming gas. The solvent such as hydrocarbon, aether and aldehyde etc with boiling point of 50- 160℃ can be used as vesicant.
Packing and Storage :
Kraft-paper bag, Net Weight of 25±0.2kg per bag ; the product should be stored in dry and ventilated warehouse, to prevent sunlight and moisture, stack height no more than 10 bags, It is not dangerous cargo.
Advantage of CPVC Resin
CPVC resin has excellent high temperature resistance, corrosion resistance and flame retardant properties, widely used in production of different industrial pipe, hot and cold water pipe and fire fighting pipeline, superiority as follows :
(1) Widely use scope: CPVC the vicat softening point higher 40℃ than PVC resin, rigid PVC products safe use of the average temperature is not more than 60℃, and CPVC hard products can be used between 40℃ and 98 ℃ for a long time, it`s the few polymer can be used in high temperature and high pressure.
(2) The superior mechanical properties : CPVC tensile strength than PVC increases by about 50%, than ABS resin, PP resin increases by about 1 times. Especially close to 100℃, CPVC can still maintain a strong rigidity, can fully meet at this temperature to the requirements of the equipment and pipeline.
(3) Chemical resistance: CPVC not only in room temperature resistance to chemical corrosion performance is excellent, and at higher temperature still has the very good acid and alkali resistance, chemical resistance, far better than PVC and other resin.
(4) Good flame retardant : CPVC excellent flame retardant automatic quench, the time limit oxygen index is sixty, because in the air will not fire, with no flame drip, restricted diffusion flame and the smoke generation characteristics.
(5) Thermal conductivity: heat conduction coefficient of CPVC is only 0.105 KW/(mk), with CPVC processing of heat pipe, heat loss, less of heat insulating layer.
(6) From the influence of residual chlorine in water, Polyolefin materials (such as PP, PE) meet water residual chlorine can be decomposed, and CPVC is not be water residual chlorine influence, won't appear crack and drip.
(7) Processing formability: The same processing methods with PVC products, very easy and convenient
