ڇا يو وي سي لائٽ وائرس ۽ بيڪٽيريا کي ماري سگهي ٿي?؟

وقت: 2020-04-21

For decades, scientists have been devoted to the research of UVC light for disinfection, especially when the UVC market is huge and the human pursuit of health is more important than ever before.

More and more reports indicate that UVC light products can kill viruses and bacteria higher than a 99.9% rate, which directly leads to the crazy purchase of UVC products.

But in fact, few people know exactly what UVC light is and whether UVC light is useful for sterilization.

Next, we'll explain in detail what UVC lights are, how they work, their precautions for use and some commercial applications to help you gain a clear understanding.

Wha is UVC light?

جيئن ته اسان سڀ knowاڻون ٿا ، سج جي روشني مختلف طول موج تي هلڪي توانائي جو هڪ ميلاپ آهي.

طول جي موج 380 نانو ميٽر کان (nm) کان 780 nanometer (nm) تائين ڏسڻ واري روشني سڏيو وڃي ٿو ، جڏهن ته موج جي ڊيگهه جي حد کان ٻاهر جيڪي پوشیدہ روشني سڏجن ٿيون.

Ultraviolet light is a type of invisible light ranging from 10 nm to 400 nm. And the function of UV light depends on the range of wavelength.

  • UV-A: 320nm کان 400 nm تائين

It makes up the majority of UV light reaching the Earth. And it can damage our skin.

  • UV-B: 280nm کان 320nm تائين

اهو چمڙي جي بيمارين جو علاج ڪري سگهي ٿو. پر گهڻو ڪري اچڻ جلن ۽ چمڙي جي ڪينسر جو سبب بڻجندو. ۽ صرف 2٪ کان گهٽ UVB زمين تائين پهچي سگهي ٿو.

  • UV-C: 200nm کان 280nm تائين

It is particularly good at sterilizing. But its penetration ability is very weak. Before reaching the ground, all UVC light will be absorbed by ozone in the atmosphere. That means, standing under the sun is useless for sterilization.

  • In summary: UV light Rule

نن theي موج جي ڊيگهه ، توانائي وڌيڪ مضبوط آهي ، پر اهو ڪم جو ڪمزور آهي ، آهستي آهستي اهو غائب ٿي ويندو آهي.

Because UVC light can be used for sterilization, coupled with the epidemic environment, the market demand for UVC products can be described as Crazy now.

۽ مارڪيٽ جو قدر 140,000,000،500,000,000،XNUMX آمريڪي ڊالر کان به وڌي XNUMX،XNUMX،XNUMX آمريڪي ڊالر تائين وڌي ويو.

The big question right now may be how does UVC light work and can it kill viruses & bacteria?

How does UVC light work?

Before the deep study of UVC light, I thought all sunlights have the sterilization effect. Bacteria and viruses will be killed by "sunburn" or heat.

But that's not the truth.

  • Sterilization Principle of UVC light

In fact, UVC light will destroy the DNA or RNA of the bacteria & viruses, without the use of chemicals, making them inactive and unable to reproduce.

Since the lifespan of single bacteria & viruses is very short, once they lose the reproduce ability, it means death. So the purpose of sterilization has been achieved.

In scientific research, it has been found that UVC light can use very little time to finish the disinfection process and make most microbes reduction up to 99.99%.

Research of UVC light

Based on this information, UVC light is believed to be quiet effective at killing viruses and bacteria.

However, the vitality of different viruses and bacteria are different. Some bacteria&viruses may be injured once they are exposed to UVC light, while others are not.

If the UV dose is insufficient, some viruses will only temporarily lose activity, and then slowly repair their own structure.

  • Special requirements of UVC lights

At present, there are no specific figures to show how much UV dose flu viruses needs to be killed. Maybe 1,085 mJ / cm2 or 3,640 mJ / cm2 . Anyway, a huge number.

You may be wondering if we stand under the sunlight containing UVC light, can we be disinfected by it?

Unfortunately, the answer is no. Although the sterilization ability of UVC light is extremely strong, the penetration ability to objects (including air) is extremely weak. Before reaching the ground, all UVC light will be filtered out by ozone in the atmosphere.

ان ڪري اسان کي ڌاتوءَ حاصل ڪرڻ جي لاءِ الٽراوائلٽ ڊزائيننگ لمپ وانگر ساڳيو ڪيريئر استعمال ڪرڻ جي ضرورت آهي.

Please pay attention to the fact that most UV lamps on the market are only designed to meet the common standard, that is, 40mJ / cm2 UV dose required for a 99.99% inactivation rate.

Study result of UVC light

Further considering the decay of UVC light in the air, those lamps make no sense for disinfection.

تنهنڪري آساني سان ڪجهه ڪمپني جي چوڻ تي يقين نه ڪريو "اسان وائرس ۽ بيڪٽيريا کي ماري سگهون ٿا" ، ڪڏهن ڪڏهن اهو صرف مارڪيٽنگ ٻولي آهي.

اسان کي اهو احساس رکڻو پوندو ته صرف يو آءِ لیمپ جي چونڊ ۾ مهارت ، وقت ۽ قيمت ئي اهم عنصر آهن.

Are ultraviolet lamps containing uvc light safe?

Although UVC light can indeed kill viruses and bacteria, there are various problems with household ultraviolet disinfection lamps on the market:

(1) روايتي الٽرايوائلٽ ڊزائينشن لیمپ وڏا آهن (گهٽ ۾ گهٽ 40 سي ايم قد يا وڌيڪ) ، گهٽ ڪارڪردگي. 1W LED لائٽ ذريعو بنيادي طور تي صرف 1 چورس ميٽر جڳهن جو احاطه ڪري سگهي ٿو.

(2) گھڻائي الٽراوائلٽ ڊيسينشن لیمپ جي روشني جو ذريعو مرکري تي مشتمل هوندو آهي ، جيڪو ماحول توڙي صحت کي خراب آهي جيڪڏهن ڇڏيل هجي.

(3) گھڻائي الٽرايوليٽ ڊس انفريشن لیمپ وسيع اسپيڪٽرم لیمپ آھن جن ۾ يو وي سي ، يو وي اي ، ۽ يو وي بي شامل آھن ، جيڪي اوزون پيدا ڪرڻ جا امڪان آھن ، جن جي ڪري جھيا ، ٿڪڻ ، ڇٽ جي تنگي ، nausea ۽ ياداشت جي نقصان.

Applications of UVC light

From this perspective, the main application scenarios of UVC light should be industrial types to maintain safe.

Applications of uvc light

To make better use of UVC light, we have developed a new lighting technology, which can make the UVC energy in a very small size with 3.5mm x 3.5mm without mercury.

هن سائيز سان ، اهو ڪيترن ئي پورٽبل سامان ۾ لاڳو ٿي سگهي ٿو ڊسڪ جي ڪارڪردگي سان.

(1) مٿاڇرو

آلود ٿيل سطحون جهڙوڪ اسپتال جا ڪمرا ۽ سامان ، رهڻ وارا ڪمرا ، هوائي اڏي ۽ تقريبن تمام عوامي جڳهه يا نجي شيون.

(2) پاڻي

Mercury-free UVC light is a clean and safe water disinfectant, UVC LED based solutions tackle these pathogens without impacting the water's smell, taste or mineral contents.

اسان پاڻي صاف ڪرڻ واري نظام يا ٽوائلٽ سسٽم ۾ يو وي سي حل استعمال ڪري سگهون ٿا.

(3) هوا

فضائي صاف ڪندڙ 99.97٪ هوا وارين ذرات کي ڪ removeي ڇڏيندا آهن ، جڏهن ته ، فلٽر نن pathي پيتھوجينڪ مائڪرو عضون کي نه ڪ doندا ، جهڙوڪ انفلوئنزا.

اسان هوا صاف ڪرڻ وارو نظام يا تجارتي هوائي ڪنڊيشن ڊڪٽ سسٽم ۾ يو وي سي حل استعمال ڪري سگهون ٿا.

How to use UVC light

All in all, UVC light can indeed kill viruses and bacterial if we choose the right system for specific applications.
