I-Copper yeyona nto isebenzayo ye-antimicrobial material for surfaces.
Kangangamawaka eminyaka, kudala ngaphambi kokuba bazi ngeentsholongwane okanye ngeentsholongwane, abantu bebesazi ngamandla obhedu okubulala iintsholongwane.
Ukusetyenziswa kokuqala okurekhodiweyo kobhedu njengearhente yokubulala usulelo luvela kwi-Smith's Papyrus, eyona xwebhu lonyango lakudala elaziwayo kwimbali.
Ukusukela emva kwe-1,600 BC, amaTshayina asebenzisa iingqekembe zobhedu njengamayeza okunyanga iintlungu zentliziyo kunye nesisu kunye nezifo zesinyi.
Kwaye amandla obhedu ahlala. Iqela likaKeevil lijonge iireyili ezindala kwisiXeko saseNew York eGrand Central Terminal kwiminyaka embalwa eyadlulayo. Uthi: “Ubhedu lusasebenza kanye njengokuba lwalusenza mhla lwafakwa kwiminyaka eli-100 eyadlulayo. "Le nto yomelele kwaye i-anti-microbial effect ayihambi."
Isebenza njani kanye?
Ukwakheka kweathom ethile yeCopper inika amandla awongezelelweyo okubulala. Ubhedu ineelektroni simahla kwiqokobhe yayo yangaphandle orbital elektroni ngokulula ithatha inxaxheba reactions oxidation-ukunciphisa (nto leyo eyenza isinyithi umqhubi olungileyo).
Xa i-microbe ihleli phezu kobhedu, ii-ion zidubula i-pathogen njengokuhlaselwa kwemijukujelwa, ithintela ukuphefumla kweseli kunye nokugqobhoza imingxuma kwinwebu yeseli okanye i-virus kunye nokudala iiradicals zasimahla ezikhawulezisa ukubulala, ngakumbi kwindawo eyomileyo. Okona kubaluleke kakhulu, ii-ion zifuna kwaye zitshabalalise i-DNA kunye ne-RNA ngaphakathi kwebhaktheriya okanye intsholongwane, ukuthintela utshintsho oludala iibhugi ezinkulu ezinganyangekiyo ngamachiza.
Ngaba i-COVID-19 ingaphila kumphezulu wobhedu?
Uphononongo olutsha lufumanise ukuba i-SARS-CoV-2, intsholongwane ebangela ubhubhani we-corona-virus, ayisasuleli kubhedu phakathi kweeyure ezi-4, ngelixa inokuphila kwindawo yeplastiki kangangeeyure ezingama-72.
I-Copper inezixhobo zokulwa ne-antimicrobial, oku kuthetha ukuba inokubulala ii-microorganisms ezifana neebhaktheriya kunye neentsholongwane. Nangona kunjalo, i-microorganism kufuneka idibane nobhedu ukuze ibulawe. Oku kubhekiselwa kuko "njengokubulala umntu odibana naye."
Ukusetyenziswa kobhedu lwe-antimicrobial:
Esinye sezicelo eziphambili zobhedu kwizibhedlele. Ezona ndawo ziyingozi kakhulu kwigumbi lasesibhedlele - iintsimbi zokulala, amaqhosha okufowuna, iingalo zesitulo, itafile yetreyi, igalelo ledatha, kunye ne-IV pole - kwaye endaweni yazo kufakwe izinto zobhedu.
Xa kuthelekiswa namagumbi enziwe ngezinto zendabuko, kwakukho ukunciphisa i-83% yomthwalo webhaktheriya kwiindawo zokuhlala emagumbini anamacandelo obhedu. Ukongeza, amazinga osulelo lwezigulane athotywa ngama-58%.
Izixhobo zobhedu zinokuba luncedo njengendawo yokulwa neentsholongwane ezikolweni, kumashishini okutya, iihotele zeeofisi, iindawo zokutyela, iibhanki njalo njalo.
