Benwei UV lamps are our common 0.9m UV lamps with powerful sterilization and disinfection functions. There are T8 ultraviolet lamps and T5 ultraviolet lamps.
Disinfect the air and leave the room in time after turning on the power. .When disinfecting the surface of the object, the lamp tube should be parallel to the surface of the object to be disinfected. Leave in time after turning on the power.
Precautions for UV lamp sterilization
1. The surface should be wiped lightly with an alcohol cotton ball frequently (usually once every 2 weeks) to remove dust and grease on the surface to reduce the impact on UV penetration. The room should be kept clean during ultraviolet disinfection. Ultraviolet rays can't reach the shaded places that are covered, so pay attention to it when using it. The surface that does not penetrate ultraviolet rays (such as paper, cloth, etc.), only the side directly irradiated can achieve the purpose of disinfection. Therefore, it must be turned on time so that all sides can receive a certain dose of irradiation. . Indoor air disinfection.
2. Speaking of ultraviolet germicidal lamps, many people think that this is a patent for medical institutions and food hygiene. Indeed, there are few household ultraviolet germicidal lamps on the market. In fact, it is as simple as that now, just use it like ordinary fluorescent lamps. Just install it on the light stand.
3. Generally, the disinfection effect can be achieved in about 30 minutes. The lamp can radiate strong 253.7nm short-wave ultraviolet rays. After half an hour of exposure, turn off the power to complete the disinfection. In the absence of protective measures, ultraviolet rays can cause direct damage to the human body. Please check the relevant knowledge on the Internet for specific conditions! Ultraviolet germicidal lamps have the strongest germicidal power in the UV-C band of ultraviolet rays, of which the 250-270nm range is the strongest.
4. Because the resonance spectrum of mercury is 2537A, this sterilization tube can generate 253.7nm ultraviolet light, which denatures bacterial and viral DNA and RNAV and prevents cells from reproducing. Ultraviolet disinfection lamps are effective against any bacteria or viruses, and concentrated high-intensity ultraviolet rays can be sterilized in a short time. It is widely used for disinfection and sterilization of air, various material surfaces, water or other liquids.
The detection of the use method of ultraviolet lamp sterilization
You buy a UV intensity detector, a few hundred yuan each!
Hang the UV germicidal lamp at a height of about 2 meters above the ground. Turn on the UV germicidal lamp. After 30 minutes, test its UV intensity at one meter vertical!
The national standard is that the intensity of 30W ultraviolet rays is at least 70μm/cm2. For ordinary domestic manufacturers, the intensity of 30W quartz ultraviolet germicidal lamps is about 100μm/cm2!
The use of ultraviolet lamp sterilization
The service life of the ultraviolet lamp is based on the attenuation of the radiated ultraviolet light as the standard.
Generally, the internationally accepted standard use time, low-power-density lamps, the power density is 40~80W/cm, and the service life is more than 1000h. The products of industrially developed countries will be determined by this standard as 2000h. High-power density lamps have a power density greater than 80W/cm and a service life of 600-800h. Products in developed countries will be determined as 1000h by this standard.
It should be noted that the end of the life of the uv lamp does not mean that it cannot be used, but that the available ultraviolet intensity generated by the lamp under the same energy input is not enough, that is to say, the low output power of ultraviolet light causes energy loss and cannot meet the curing requirements.
