Hospital Medical airtight Sliding Door The medical automatic door is a door that is generally installed in the operating room or the ICU ward for the medical staff to push in and out of the hospital bed. The medical automatic door has the function of inductive opening and safety anti-pinch. The medical staff only needs to extend the foot into the light control foot sensing box next to the entrance, and the door will automatically close.
After a period of time, the door will automatically close after the cart and medical staff have fully entered. If someone or a cart is next to the door leaf, the door will not close to provide a safe anti-pinch. In addition, the door frame of the medical automatic door is made of sealed profile, which has the characteristics of high air tightness; the light control foot sensing is adopted for the entrance and exit, so that the medical staff can open the door [without contact", which can effectively isolate the bacteria and personnel.

The frequency of electromagnetic waves listed in the National Standard for Environmental Electromagnetic Waves (GB 9175-88) of the People's Republic of China is above 100KHz. The frequency of AC power in our country is only 50Hz, which is far below the frequency of harmful radiation. Therefore, the harmful radiation itself is basically non-existent, but in fact our carbon fiber heating cable is actually a heating element with a higher heat, and its frequency is the same as the frequency of the power supply. The electromagnetic field produced by it is far lower than the electromagnetic field produced by electrical work, so the impact on people is negligible. Therefore, we recommend that you do not panic too much. So why are people so sensitive to the word radiation? In fact, this ability is very much related to people's misdirection and lack of understanding. And our experts in electric heating also introduced a lot of installation of electric floor heating. Many customers in the installation of floor heating are the first considerations and concerns that are electromagnetic radiation problems. Our experts warmly reminded, it is recommended: we do not blindly panic, because many people on electromagnetic Do not understand, so there is a fear of psychology.
Experts briefly analyze the electromagnetic radiation related knowledge of heating cables
1. The book “Conclusion and Recommendations of the WHO International Electromagnetic Field Program Evaluation†stated in the book that the public often encounter in life is the low-frequency 0-100kHz electric field level, and it does not have any actual health problems. The WHO low-frequency field health risk assessment concluded that for the electric field, the public usually encounters the level of extremely low-frequency electric fields, and there is no actual health problem;
Second, in electromagnetics, 50Hz power frequency radiation is called electromagnetic induction, its radiation properties are weak, and will not affect the human body.
3. The “Regulations on Protection against Electromagnetic Radiation†(GB8702-88) formulated by the State Environmental Protection Administration The scope of protection limits in this regulation is 100KHZ to 300GHZ. The frequency of the heating cable is 50HZ, which is not included in the electromagnetic radiation protection limit at all. Therefore, our experts in carbon wall warming suggest that we should not be excessive panic.
Fourth, China's safety standards for electromagnetic radiation are far more stringent than in Europe and the United States: China's current electromagnetic radiation protection standard (GB8702-88) has a value of 40 microwatts/cm2, which is more stringent than that of industrialized countries in Europe and America. See the table below for details. Unit: microwatt/square centimeter National Electromagnetic Radiation Protection Safety Standard
United States <3000
EU <450
China <40
For instruments related to battery radiation detection, the measurement range is also divided. As far as I know, no instrument can be used to detect the magnetic field strength of all frequency electromagnetic waves. Some people use low-frequency detectors to detect the field strength of high-frequency appliances. Our correct approach is to use low-frequency detectors to detect low frequencies.
Carbon fiber is a kind of fiber material with chemical inertness and intrinsic semi-conductor properties of carbon materials. It is a carbon material and has a light weight, high elastic modulus, high temperature resistance, corrosion resistance, high electrical conductivity, high thermal efficiency, and low coefficient of friction. Other excellent performance. After special treatment of carbon fiber material, with stable electrical properties, with many other advantages of resistance materials can not be compared, such as: use in a specific environment, strong anti-oxidation performance, long service life; heating power is stable, at a power of 500W (Including 500W) The following uses electrothermal conversion efficiency up to 100%, and above 500W, the electrothermal conversion efficiency is 98%. Compared with the widely used metal wires, PTC, and silicon carbide electric heaters, the thermal efficiency is improved by 30 to 40%, and the electric heating power is hardly attenuated. It can be heated to 3000°C in a specific environment without any change in its mechanical properties and elastic modulus. In addition, the carbon fiber material is used in an electrothermal state, does not follow the Weideman-Franz law, and mainly depends on the lattice vibration of the lattice wave to overcome the low strength of the wire, the PTC, and the silicon carbide heating body. The disadvantage of oxidation. Nowadays it has become an outstanding new material that combines many superior features.
Far-infrared carbon fiber far-infrared radiation heating system uses clean energy—electric energy, clean and pollution-free. Each room is heated independently, and the temperature of each room can be adjusted to make it easier to operate. Installed under the floor heating speed, more energy-efficient, warm feet and feet in line with the body's requirements for heating comfort, feel more comfortable. Far-infrared radiant heat principle promotes blood circulation and health products are healthier.
Implementation of the standard "Radiation heating and cooling technology specification" JGJ142-2012;
In August 2012, the Ministry of Housing and Urban-Rural Development officially approved the “Technical Specification for Radiant Heating and Cooling†(No. JGJ 142-2012, hereinafter referred to as “New Regulationâ€) as an industry standard, and is scheduled to be implemented on June 1, 2013. . Compared with the revised "Technical Specification for Ground Radiant Heating" (JGJ 142-2004) before the revision, the new regulation not only adds new contents such as radiation cooling, electric heating film (cable), electric floor heating, foamed cement insulation layer, etc. The original water and floor heating content has also been modified to some extent, such as increasing the effective heating (cooling) amount of the radiant surface and the test method for the reverse heat transfer (cold) amount. As China's only department-level technical specification that specifically addresses the radiant heating and cooling industry, the new regulations will “protect and escort†the healthy development of the radiant heating and cooling industry.

Today, with the rapid development of science and technology, many furniture appliances such as computers and televisions are used by people in our lives. In the face of numerous things with radiation, each of us fears that our bodies will be hurt unnecessarily. In recent years, our electric floor heating system has been used by many people in our home life. However, at the same time, people are also worried that the warm radiation will affect people's health. In fact, our floor heating really has Does radiation really affect our healthy life?
