1. Chii chinonzi UV?

Kutanga, ngationgororei pfungwa yeUV. UV, kureva ultraviolet, kureva ultraviolet, i electromagnetic wave ine wavelength pakati pe10 nm ne400 nm. UV mumabhendi akasiyana anogona kukamurwa kuita UVA, UVB uye UVC.

UVA: ine wavelength yakareba kubva ku320-400nm, inogona kupinda mumakore uye girazi muimba uye motokari, inopinda mukati meganda reganda uye inokonzera tanning. UVA inogona kupatsanurwa kuita uva-2 (320-340nm) uye UVA-1 (340-400nm).

UVB: wavelength iri pakati, uye wavelength iri pakati pe280-320nm. Ichatorwa neozone layer, ichikonzera kupisa kwezuva, kutsvuka kweganda, kuzvimba, kupisa uye kurwadziwa, uye kuputika kana kusvuuka muzviitiko zvakakomba.

UVC: iyo wavelength iri pakati pe100-280nm, asi iyo wavelength pazasi 200nm is vacuum ultraviolet, saka inogona kutorwa nemhepo. Naizvozvo, iyo wavelength iyo UVC inogona kuyambuka mhepo iri pakati pe200-280nm. Kana hupfupi hwayo hurefu hwayo, hunowedzera njodzi. Zvisinei, inogona kudziviswa neozone layer, uye zvishoma chete zvichasvika pamusoro penyika.

2. Nheyo yeUV sterilization?

UV inogona kuparadza DNA (deoxyribonucleic acid) kana kuti RNA (ribonucleic acid) mamolecular structure etwupukanana, zvekuti mabhakitiriya anofa kana kuti haakwanise kuberekana, kuti azadzise chinangwa chekuuraya.

3. UV sterilization bhendi?

Maererano neInternational ultraviolet Association, “ultraviolet spectrum (nzvimbo ‘yokubvisa utachiona’) iyo inokosha zvikuru pakuuraya utachiona hwemvura nemhepo ndiyo inotorwa neDNA (RNA mune mamwe mavhairasi). Iri bhendi rekuita sterilization rinenge 200-300 nm ”. Izvo zvinozivikanwa kuti sterilization wavelength inosvika kupfuura 280nm, uye ikozvino inowanzoonekwa kuti inosvika ku300nm. Zvisinei, izvi zvinogonawo kuchinja nekutsvakurudza kwakawanda. Vesainzi vakaratidza kuti ultraviolet light ine wavelengths pakati pe280nm ne300nm inogona kushandiswawo kuita sterilization.

4. Ndeupi wavelength yakanyatsokodzera yesterilization?

Pane kusanzwisisa kuti 254 nm ndiyo yakanakisa wavelength yesterilization, nekuti iyo peak wavelength yepasi-pressure mercury rambi (inotemerwa chete nefizikisi yemwenje) i253.7 nm. Muchidimbu, sezvakatsanangurwa pamusoro apa, imwe mhando yewavelengths ine bactericidal effect. Nekudaro, zvinowanzoonekwa sewavelength ye265nm ndiyo yakanyanya kunaka, nekuti iyi wavelength ndiyo yepamusoro yeDNA yekunyudza curve. Naizvozvo, UVC ndiro bhendi rakakodzera kwazvo rekuita sterilization.

5. Sei nhoroondo yakasarudza UVCLED?

Nhoroondo, mercury rambi ndiyo chete sarudzo yeUV sterilization. Nekudaro, iyo miniaturization yeUVC LEDzvikamu zvinounza kumwe fungidziro kune chiitiko chekushandisa, mazhinji ayo asingagone kuwanikwa neagara mercury marambi. Mukuwedzera, UVC inotungamirirwa inewo zvakawanda zvakanaka, zvakadai sekukurumidza kutanga, nguva inobvumirwa kuchinja, kuwanikwa kwebhatiri magetsi uye zvichingodaro.

6. UVC LED application mamiriro?

Surface sterilization: yakakwirira frequency yeruzhinji yekuonana nenzvimbo dzakadai semidziyo yekurapa, zvekushandisa zveamai nevana, chimbuzi chakangwara, firiji, tableware cabinet, fresh-cheep box, intelligent trash gaba, thermos cup, escalator handrail uye bhatani remuchina wekutengesa tikiti;

Yakadaro mvura sterilization: tangi yemvura yemuchina wemvura, humidifier uye ice maker;

Kuyerera kwemvura inoyerera: inoyerera mvura sterilization module, yakananga yekunwa mvura dispenser;

Air sterilization: air purifier, air conditioner.

7. Ungasarudza sei UVC LED?

Inogona kusarudzwa kubva pamaparamita akadai sesimba remaziso, peak wavelength, hupenyu hwebasa, kona yekubuda uye zvichingodaro.

Simba reOptical: iyo UVC LED Optical power inowanikwa mumusika wazvino inotangira pa2MW, 10 MW kusvika zana MW. Zvikumbiro zvakasiyana zvine simba rakasiyana zvinodiwa. Kazhinji kutaura, iro simba remaziso rinogona kuenzaniswa nekubatanidza kureba kwe irradiation, kudiwa kwesimba kana static kudiwa. Iyo yakakura kureba kweradiation, kunowedzera simba kudiwa, uye kukura kwesimba rekuona rinodiwa.

Peak wavelength: sezvataurwa pamusoro apa, 265nm ndiyo yakanakisa wavelength yesterilization, asi tichifunga kuti pane musiyano mudiki mukukosha kwekukosha kwepeak wavelength pakati pevagadziri, kutaura zvazviri, simba remaziso ndiyo inonyanya kukosha indekisi yekuyera sterilization kunyatsoshanda.

Hupenyu hwesevhisi: funga nezve kudiwa kwehupenyu hwesevhisi zvinoenderana nenguva yesevhisi yemashandisirwo chaiwo, uye tsvaga yakanyatsokodzera UVC inotungamirwa, inova yakanyanya kunaka.

Chiedza chinobuda pakona: kona yemwenje yekubuda kwemwenje yemarambi akavharidzirwa nelenzi yendege kazhinji iri pakati pe120-140 °, uye kona yekubuda kwechiedza yakavharidzirwa nespherical lens inogadziriswa pakati pe60-140 °. Muchokwadi, zvisinei kuti yakakura sei kona yekubuda kweUVC LED inosarudzwa, ma LED akakwana anogona kugadzirwa kuti avhare zvizere nzvimbo inodiwa yekubereka. Muchiitiko chisinganzwisisike kune sterillization renji, kakona kadiki kechiedza kanogona kuita kuti mwenje uwedzere kudzika, saka nguva yesterilization ipfupi.
