Kev ceev faj rau kev siv cov tshuaj tua kab mob ultraviolet hauv tsev

Ultraviolet sterilization yog ua kom puas thiab hloov DNA (deoxyribonucleic acid) qauv ntawm cov kab mob los ntawm kev siv hluav taws xob ultraviolet, kom cov kab mob tuag tam sim lossis tsis tuaj yeem tsim lawv cov xeeb ntxwv, thiaj li ua tiav lub hom phiaj ntawm kev ua kom tsis muaj menyuam. Qhov ua kom tsis muaj menyuam tiag tiag yog UVC ultraviolet rays, vim tias C-band ultraviolet rays yooj yim cuam tshuam los ntawm cov kab mob. DNA nqus, tshwj xeeb tshaj yog cov nyhuv ntawm ultraviolet rays nyob ib ncig ntawm 253.7nm yog zoo dua. Ultraviolet sterilization yog ib txoj kev siv tshuaj tua kab mob hauv lub cev ntshiab, yooj yim thiab yooj yim, tsis muaj kev ua qias tuaj, thiab daim ntawv thov ntau yam ntawm cov teeb hluav taws xob tua kab mob hauv tsev tau txuas ntxiv nthuav dav. Cia's tham txog kev ceev faj rau kev siv tshuaj tua kab mob ultraviolet hauv tsev.

1. Tsis txhob' tsis txhob cia lub teeb ci ultraviolet irradiate neeg, thiaj li tsis ua mob. Ultraviolet rays muaj kev cuam tshuam rau tib neeg cov tawv nqaij thiab qhov muag. Lub sij hawm luv luv rau tib neeg lub cev yuav ua rau liab, khaus, thiab ua xua pob liab liab; Kev raug mob mus ntev tuaj yeem ua rau muaj kev puas tsuaj loj rau cov ntaub so ntswg ntawm daim tawv nqaij, thiab kev raug mob txaus tuaj yeem ua rau mob qog noj ntshav. Ultraviolet rays kuj cuam tshuam rau tib neeg lub qhov muag. Kev phom sij heev, luv luv thiab siv tshuaj ntau heev tuaj yeem ua rau lub qhov muag liab thiab o, kua muag, thiab tsis muaj peev xwm qhib qhov muag. Kev raug ultraviolet ntev ntev tuaj yeem ua rau cataracts thiab txawm tias qhov muag tsis pom.

2. Thaum siv cov kab hluav taws xob ultraviolet los tua cov kab mob ntawm cov khoom, qhov chaw yuav tsum tau irradiated yuav tsum ncaj qha irradiated nrog ultraviolet lub teeb thiab ncav cuag ib tug txaus hluav taws xob koob. Vim yog qhov kev nthuav tawm ntawm lub teeb, thaum cov khoom raug thaiv, kev xav, kev nkag los yog nqus yuav tshwm sim. Ultraviolet tshuaj tua kab mob yuav tsum tau hais tias lub wattage ntawm lub teeb ultraviolet ib cubic meter ntawm qhov chaw yog ≥1.5W, thiab lub sij hawm irradiation feem ntau yog 30 mus rau 60 feeb. Nws kuj tau hais tias qhov kev siv ntawm ultraviolet hluav taws xob yuav tsum tsis txhob tsawg dua 70 ūW / cm2, txwv tsis pub cov nyhuv sterilization tsis zoo los yog tsis muaj txiaj ntsig, thiab kev ua kom tsis muaj menyuam yuav tsis ua tiav. Lub hom phiaj.

3. Qhov ntsuas kub tsim nyog rau kev tua kab mob UV yog 20 ℃ ~ 40 ℃. Qhov kub thiab txias dhau lawm yuav cuam tshuam rau kev tua kab mob. Thaum siv UV tshuaj tua kab mob hauv tsev, ua kom chav huv huv thiab qhuav kom tsis txhob muaj plua plav thiab dej pos huab. Thaum qhov ntsuas kub qis dua 20 Thaum qhov kub siab tshaj 40 ° C thiab cov txheeb ze av noo siab dua 60%, lub sij hawm irradiation yuav tsum tau txuas ntxiv kom tsim nyog.

4. Ua tib zoo so thiab ntxuav lub teeb hauv daim ntawv thov. Thaum siv lub teeb tshiab, siv 75% cawv gauze los so lub teeb lub raj kom tshem tawm cov plua plav thiab roj stains ntawm lub teeb raj. So tsis tu ncua thaum siv, thiab ntxuav lub teeb lub raj kom tsis txhob cuam tshuam rau lub teeb pom kev zoo thiab kev siv hluav taws xob.
