Kwapera gore kubva pakatanga Covid-2019.Muna 2020, vanhu kutenderera pasirese vari kurarama mumhepo inotyisa yedenda.Zvinoenderana nehuwandu hwakaburitswa neJohns Hopkins University muUnited States, kubva 23:22 muna Ndira 18, Beijing nguva, Huwandu hwenyaya dzakasimbiswa dzemabayo matsva pasi rose dzakakwira kusvika pa95,155,602, idzo 2,033,072 vakafa.Mushure medenda iri, nzanga yese yakawedzera ruzivo rwehutano hwayo, uye chimiro cheindasitiri yekuuraya hutachiona uye yekuchenesa mukuchengetedza hupenyu hwevanhu uye hutano hwave nani pasina mubvunzo.Pakati pavo, ultraviolet LED sterilization, senzira yekudzivirira disinfection, yakawedzerawo kukurumidza kwekukura nekuda kwe catalysis yedenda.
Ultraviolet disinfection inzira yechinyakare uye inoshanda.Munguva yeSARS, nyanzvi kubva kuInstitute of Viral Disease Control and Prevention yeChinese Center for Disease Control and Prevention yakawana kuti kushandiswa kwemwaranzi yeultraviolet ine simba rinopfuura 90μW/cm2 kwemaminetsi makumi matatu kuvhenekera coronavirus kunogona kuuraya SARS. utachiona.Iyo "New Coronavirus Infection Pneumonia Diagnosis uye Kurapa Chirongwa (Trial Version 5)" yakaratidza kuti iyo coronavirus itsva inonzwa kune ultraviolet mwenje.Nguva pfupi yadarika, Nichia Chemical Industry Co., Ltd. yakazivisa kuti mukuyedza kushandisa 280nm yakadzika ultraviolet LEDs, zvakasimbiswa kuti iyo nyowani coronavirus (SARS-CoV-2) yekudzima moto mhedzisiro mushure memasekondi makumi matatu eyakadzika ultraviolet irradiation yaive 99.99%.Naizvozvo, mune dzidziso, iyo sainzi uye zvine musoro kushandiswa kwe ultraviolet mwenje inogona kunyatso misa coronavirus.
Kubva pane yazvino mashandisiro ekuona, yakadzika ultraviolet ma LED anoshandiswa zvakanyanya muminda yevagari vemo sekuchenesa mvura, kucheneswa kwemhepo, kuuraya hutachiona hwepasi, uye kuona biological.Pamusoro pezvo, kushandiswa kwechiedza cheultraviolet masosi kwakatonyanya kudarika sterilization uye disinfection.Iyo ine zvakare tarisiro yakafara mundima dzakawanda dziri kusimukira dzakadai sekuona biochemical, sterilization uye kurapwa, polymer kurapa uye maindasitiri photocatalysis.
Zvichienderana nehukuru hwekushandisa kweyakadzika ultraviolet LED, yakadzika ultraviolet LED inogoneka zvachose kusimudzira kuita indasitiri itsva yetrillion-level yakasiyana nemwenje we LED muna 2021. Sezvo LED ine zvakanakira zviduku uye zvinotakurika, zvakatipoteredza uye zvakachengeteka, zviri nyore kugadzira. uye pasina kunonoka kuvhenekera, kuiswa kweyakadzika ultraviolet LED kuri nyore kukwidziridzwa kune inotakurika disinfection zvigadzirwa zvemagetsi, senge sterilizer yaamai nemwana, lifti handrail sterilizer, mini yekuwachisa muchina wakavakirwa muUV Germicidal mwenje, marobhoti anotsvaira, nezvimwe. mercury rambi ultraviolet mwenje, UVC-LED ine yakakwira simba density, iri nyore kushandiswa munzvimbo diki dzakavharirwa.Inogona kugarisana nemunhu uye muchina.Inokunda zvikanganiso zvevanhu nemhuka izvo zvinofanirwa kudururwa panguva yebasa rechinyakare mercury rambi ultraviolet marambi.UVC -LED zvikumbiro zvine hombe nzvimbo yekushandisa munguva pfupi iri kutevera.
