Ultraviolet hluav taws xob muaj kev cuam tshuam rau tib neeg daim tawv nqaij, qhov muag, thiab hauv nruab nrab lub paj hlwb.Nyob rau hauv qhov muaj zog ntawm cov hluav taws xob ultraviolet, photodermatitis tuaj yeem tshwm sim;Cov mob hnyav kuj yuav ua rau mob qog noj ntshav.Thaum raug ultraviolet hluav taws xob, qhov degree ntawm qhov muag raug mob yog proportional rau lub sij hawm, inversely proportional rau lub square ntawm deb ntawm qhov chaw, thiab muaj feem xyuam rau lub kaum sab xis ntawm lub teeb projection.Ultraviolet rays ua rau lub hauv nruab nrab lub paj hlwb thiab tuaj yeem ua rau mob taub hau, kiv taub hau, thiab ua kom lub cev kub.Ua rau ntawm qhov muag, nws tuaj yeem ua rau mob conjunctivitis thiab keratitis, hu ua photogenic ophthalmia, thiab kuj tuaj yeem ua rau mob cataracts.Yuav ua li cas tiv thaiv kev ntsuas thaum ua haujlwm ntawm UV aging test chamber.

1. Ntev wavelength ultraviolet teeb nrog UV wavelengths ntawm 320-400nm tuaj yeem ua haujlwm los ntawm kev hnav khaub ncaws ua haujlwm hnyav me ntsis, UV tiv thaiv iav nrog fluorescence li kev ua haujlwm, thiab cov hnab looj tes tiv thaiv kom ntseeg tau tias daim tawv nqaij thiab qhov muag tsis raug UV hluav taws xob.

2. Lub sij hawm ntev raug rau lub nruab nrab yoj ultraviolet teeb nrog lub wavelength ntawm 280 ~ 320nm tuaj yeem ua rau tawg ntawm capillaries thiab redness nyob rau hauv tib neeg daim tawv nqaij.Yog li thaum ua haujlwm nyob rau hauv nruab nrab yoj ultraviolet lub teeb, thov nco ntsoov hnav cov khaub ncaws tiv thaiv kev tshaj lij thiab cov iav tiv thaiv kev tshaj lij.

3. Ultraviolet wavelength 200-280nm luv yoj ultraviolet teeb, UV aging test chamber, luv yoj ultraviolet yog kev puas tsuaj thiab tuaj yeem ncaj qha decompose cell nucleic acid ntawm cov tsiaj thiab cov kab mob, ua rau cell necrosis, yog li ua tiav cov kab mob bactericidal.Thaum ua haujlwm nyob rau hauv luv luv ultraviolet hluav taws xob, nws yog ib qho tsim nyog yuav tsum hnav lub npog ntsej muag tiv thaiv ultraviolet kom huv si tiv thaiv lub ntsej muag thiab zam kev puas tsuaj rau lub ntsej muag thiab ob lub qhov muag los ntawm hluav taws xob ultraviolet.

Lus Cim: Cov tsom iav tiv thaiv UV thiab lub ntsej muag tuaj yeem ua tau raws li lub ntsej muag sib txawv, nrog kev tiv thaiv plaub muag thiab sab tis tiv thaiv, uas tuaj yeem thaiv UV rays los ntawm cov lus qhia sib txawv thiab tiv thaiv tus neeg teb xov tooj lub ntsej muag thiab ob lub qhov muag.
