UVC Chiedza Inoshanda kune Bhakitiriya neVhairasi?

Utachiona uye mavhairasi ma microscopic microorganisms anogona kukonzera siyana zvirwere uye

mamiriro. Kudzivirira kutapurirana kwezvirwere zvakadaro nehurwere, hutachiona uhu hunofanirwa kubviswa kubva kumusoro uye nemhepo. Kushandisa ultraviolet (UV) mwaranzi ndiyo imwe nzira inoshanda yekuita izvi. UVC chiedza yakaratidza kuti ndiyo inonyanya kushanda yeUV mwenje yekuparadza mabhakitiriya nemavhairasi. Chinyorwa chino chichatsanangura zvakadzama chinonzi ultraviolet C (UVC) mwaranzi, inoshanda sei, uye inoshanda sei pakuuraya mabhakitiriya nemavhairasi.

UVC mwenje ine wavelength pakati pe200 ne280 nanometers (nm). Iine hurefu hupfupi pane chiedza chinooneka, pamwe nemwaranzi yeUVA neUVB inobva kuzuva kwatinobudirwa nayo.Inozivikanwawo se germicidal UV nekuti inogona kubvisa DNA yezvipembenene zvakaita semavhairasi nemabhakitiriya.

UVC Chiedza Chinoshanda Sei?

UVC radiation inoshanda nekukonzeresa kukuvara kweDNA kune tupukanana senge mabhakitiriya nemavhairasi. Imwe yeayo mana nucleotides anosanganisira DNA, thymine, inoumba covalent zvisungo pamwe ari padyo thymine mamorekuru kana akafumurwa UVC mwaranzi. Izvi zvinoguma nekuumbwa kwe thymine dimer, iyo inokanganisa DNA helix chimiro uye inodzivisa kudzokorora kweDNA. Iyo microorganism haigone kutsungirira uye kubereka pasina kugona kutevedzera.

UVC radiation inofanirwa kuve neiyo wavelength uye kusimba kuti ishande. UVC chiedza  kusimba kunopimwa nema microwatts per centimeter square (W/cm2). Kusimba kunodiwa kubvisa mabhakitiriya uye mavhairasi zvinoenderana nerudzi rwemicroorganism, chinhambwe chiri pakati pechivheneko chechiedza uye microorganism, uye nguva yekuratidzwa.

UVC Radiation uye Utachiona

UVC mwenje wakaratidzwa kuve unoshanda pakurwisa akasiyana siyana ehutachiona. Mune chimwe chidzidzo, UVC chiedza yakaderedza nhamba yeStaphylococcus aureus bacteria pamusoro pepamusoro ne 99.9% mushure memasekondi mashanu chete ekuonekwa kune 0.32 W / cm2 yeUVC chiedza. Imwe miniti yekuratidzwa kune UVC mwenje ine simba re 1.8 W / cm2 yaive yakakwana kubvisa 99.9% yePseudomonas aeruginosa mabhakitiriya, maererano neimwe ongororo.

UVC chiedza yakaratidzawo kuparadza mabhakitiriya asingaurayiwi nemishonga yakawanda. Mune imwe tsvakurudzo, 10 seconds yekutarisana neUVC chiedza pane simba re 0.2 W / cm2 yakaderedza nhamba yeAcinetobacter baumannii isingagadziriswi nemishonga yakawanda pamusoro pe99.9%. Masekonzi mashanu ekuratidzwa kune 0.5 W/cm2  UVC chiedza t yakaderedza huwandu hwehutachiona hwehutachiona hweKlebsiella pneumoniae pamusoro pe99.9%, maererano nekuongorora kwakasiyana.

UVC Radiation uye Virusi

UVC mwenje unowanikwa uchishanda kurwisa mavhairasi akasiyana. Mumaminitsi gumi nemashanu, UVC chiedza  nekusimba kwe 0.1 W/cm2 yakaderedza hutachiona hwefuruwenza A ne99.99%, maererano neimwe ongororo. Mune chimwe chidzidzo, maminitsi gumi nemashanu ekuratidzwa UVC chiedza nekusimba kwe0.5 W/cm2 yakaderedza kutapukira kweconavirus yemunhu OC43 ne99.9%.

Yakaratidzawo kuti inoshanda kurwisa COVID-19-inokonzera SARS-CoV-2 hutachiona kuburikidza a ir di chivi . Mumasekonzi 25, UVC chiedza  nekusimba kwe0.1 W/cm2 yakaderedza kutapukira kwehutachiona hweSARS-CoV-2 ne99.9%, maererano neimwe ongororo. Mune chimwe chidzidzo, kuratidzwa kune UVC chiedza nekusimba kwe0.05 W/cm2 yakaderedza kutapukira kwehutachiona hweSARS-CoV-2 ne99.9% muminiti imwe chete.

Izvo zvakakosha kuti uzive kuti efficacy ye   iyo mukuparadza mavhairasi inotsamira pane zvakasiyana-siyana, kusanganisira rudzi rwevhairasi, kusimba kwechiedza, uye nguva yekuratidzwa. Nekudaro, tsvagiridzo yakaratidza kuti UVC mwenje inogona kuve chishandiso chinobatsira kudzivirira kupararira kwehutachiona senge furuwenza, vanhu coronavirus, uye SARS-CoV-2.

Kurambidzwa kweUVC Chiedza

UVC mwenje wakaratidzwa kuva unoshanda pakuuraya tupukanana nemavhairasi, asi kushandiswa kwayo kune zvishoma.

●  Chekutanga, mamicroorganisms chete anoratidzwa zvakananga kwairi anogona kuurayiwa kusanganisira iyo Mvura yeUV . Naizvozvo, nzvimbo uye zvinhu zvisingabatane zvakananga neUVC radiation zvinogona kunge zvichine mabhakitiriya nemavhairasi.

●  Chechipiri, kuratidzwa kwakananga kwairi kwenguva yakareba kunogona kukanganisa vanhu.Kunyanya kuratidzwa kunogona kutungamirira kukutsamwa kweganda, kukuvara kwemaziso, uye dzimwe nyaya dzehutano. Naizvozvo, zvakakosha kuomerera kune UVC mwenje mirairo yekuchengetedza uye kuona kuti vanhu havasi kuratidzwa zvakananga kuchiedza.

●  Chechitatu, inongokwanisa kuparadza mabhakitiriya nemavhairasi kana ikashandiswa nesimba rakakodzera uye nguva. Zvinogona kusashanda mukupedza tupukanana kana kusimba kana nguva yekuratidzwa isina kukwana.

●  Chekupedzisira, mwaranzi yeUVC inogona kusashanda kurwisa mabhakitiriya ese nemavhairasi. Mamwe ma microorganisms uye mavhairasi anogona kuramba achidzivirira kuUVC mwenje kupfuura mamwe.

Haasi ese eUV Mwenje akafanana!

Haasi ese e UV mwaranzi inoshanda zvakaenzana pakuparadza mabhakitiriya nemavhairasi. Kune akasiyana emhando dzemwenje dzeUV, imwe neimwe iine akasiyana wavelengths uye zvivakwa. Kuti unzwisise mutsauko uripo pakati pemhando dzechiedza cheUV, zvinodikanwa kuongorora ultraviolet spectrum.

UV-A uye UV-B

UV-A neUV-B ndiwo anonyanya kuzivikanwa marudzi echiedza cheultraviolet, uye ndiwo maranzi ezuva anosvika pasi pePasi. Nekudaro, mamwe mafomu emwenje weUV anowanzo kushandiswa muzvigadzirwa zvinouraya hutachiona hwemhepo.

UV-C

UV-C, inozivikanwawo se germicidal UV, ine mafungu akareba ari pakati pe200 ne280 nanometers. Iyi ndiyo nzira yakajairika yehutachiona hweUV yakashandiswa nesainzi kweanopfuura zana kuuraya utachiona hwemvura, mweya, uye nzvimbo. UV-C inoparadza uye inodzima marudzi ese ehutachiona, kusanganisira mavhairasi, mabhakitiriya, mold, uye fungi.

Kure-UVC

Far-UVC chikamu cheUV-C, chinosanganisira wavelengths pakati pe207 ne222 nanometers. Far-UVC yakasiyana pakuti inofungidzirwa kuti haina ngozi pakuratidzwa kwevanhu. Ichi chizere chechiedza chine bandwidth yakatetepa kwazvo chinoidzivirira kuti isapinda kunze kwekunze kweiyo epidermis yedu, asi inogona kuuraya mavhairasi nemabhakitiriya. Mumakore gumi apfuura, masayendisiti akatanga kutarisa kure-UVC, saka tsvakiridzo yezvingangoita mhedzisiro inogumira pane UV-C.

Pedyo neUV

Pedyo neUV inonyanya kuve neUV-A wavelengths, iyo ichine zvimwe zvinouraya hutachiona asi isingakwanise kuparadza hutachiona seUV-C. Munzvimbo dzekurapa uye nzvimbo dzekuchengeta vakuru, padhuze nechiedza che ultraviolet chinogona kubatsira kuderedza huwandu hwehutachiona hwehutachiona. Aya mawavelength ari pedyo zvakanyanya nechiedza chinooneka uye anofungidzirwa kuti akachengeteka kuvanhu.

Kana iwe’zvakare kunakidzwa nemwenje weUV uye unoda kuongorora zvimwe, tarisa Tiuhani Electronic , Vagadziri vemadhiyo yeUV LED DI !
