In addition to 75% alcohol and various disinfectants, there is actually a good disinfection method that uses ultraviolet light for disinfection. Of course, like masks and disinfectants, अतिनील दिवे are also scarce products. It is difficult to buy them in a short time. But it’ठीक आहे त्यापूर्वी, यूव्ही निर्जंतुकीकरण दिवे वापरताना कोणत्या गोष्टींकडे लक्ष देणे आवश्यक आहे त्याबद्दल प्रत्येकाने जागरूक असणे आवश्यक आहे.
The main working principle of the ultraviolet lamp is to use the released ultraviolet rays to inactivate bacteria and viruses to achieve the effect of sterilization and disinfection. As for the specific working principle of the ultraviolet lamp, the light source of the ultraviolet lamp will be mentioned. At present, there are mainly two light sources: gas discharge light source and solid-state light source.
The most common अतिनील दिवाआम्ही विकत घेऊ शकतो गॅस डिस्चार्ज लाइट स्रोत, मुख्यत: कमी-दाब पारा दिवे. त्याचे कार्य सिद्धांत फ्लूरोसंट दिवेसारखेच आहे, दिवा ट्यूबमधील पारा वाष्प नळीतील पारा अणूंना ऊर्जा देऊन अल्ट्राव्हायोलेट किरण निर्माण करतो. लो-प्रेशर पारा वाष्प सहसा 254 नॅनोमीटर यूव्हीसी अल्ट्राव्हायोलेट किरण आणि 185 नॅनोमीटर यूव्हीडी अल्ट्राव्हायोलेट किरण तयार करते.
अल्ट्राव्हायोलेट दिवाच्या निर्जंतुकीकरण तत्त्वाबद्दल बोलल्यानंतर, आम्ही पुढील विशिष्ट निवडीबद्दल विचार करू. साधारणपणे, 1 घनमीटरअतिनील दिवा should not be less than 1.5W. According to this calculation, assuming your bedroom is 20 square meters and the floor height is 3 meters, then a simple calculation can know that you need to configure a 40W ultraviolet light for your bedroom.
Another thing to note is the material of the tube. At present, there are two main glass materials for low-pressure mercury lamps on the market: quartz glass and high boron glass. The transmittance and radiation of quartz glass are higher than those of high boron glass. The penetration ability of short-wave ultraviolet rays is extremely weak, so be sure to choose quartz glass.
