Cia thiab ceev faj
1. Khaws UV 284 nyob rau hauv lub kaw ntom nti, lub teeb- tiv taus lub thawv rau hauv qhov txias, qhuav, zoo- qhov cua qhov chaw kom deb ntawm tshav kub thiab cov khoom siv tsis sib xws.
2. Khaws 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid CAS 4065-45-6 kom deb ntawm cov muaj zog oxidizing cov neeg ua haujlwm thiab cov hauv paus muaj zog los tiv thaiv kev degradation lossis kev phom sij txaus ntshai.
3. Kov UV 284 nrog kev saib xyuas kom tsis txhob muaj plua plav thiab tsis txhob ua rau daim tawv nqaij ntev ntev thiab nqus cov plua plav.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm qhov chaw nchuav, xyuas kom muaj cua, thiab hnav cov khoom tiv thaiv (lub npog ncauj, hnab looj tes, tsom iav) ua ntej ntxuav.
2. Sau cov spilled UV 284 nrog ib daim ntaub ntub dej los yog lub tshuab nqus tsev uas muaj HEPA lim. Muab cov khoom pov tseg tso rau hauv lub thawv kaw.
3. Muab pov tseg 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid CAS 4065-45-6 ntawm cov khoom uas tau sau ua tshuaj pov tseg raws li cov cai hauv zos. Ntxuav thaj chaw muaj kab mob nrog dej thiab tshuaj ntxuav tes. Tiv thaiv kev nkag mus rau hauv cov dej ntws.
Cov ntaub ntawv kev nyab xeeb
1. UV 284 tuaj yeem ua rau tawv nqaij mos thiab qhov muag khaus thaum sib cuag. Nws yog feem ntau suav hais tias tsis tshua muaj toxicity tab sis tej zaum yuav muaj teeb meem yog tias nqos tau ntau heev.
2. 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid CAS 4065-45-6 plua plav tuaj yeem ua rau ua pa ua pa yog tias nqus tau.
3. Hnav cov khoom tiv thaiv tsim nyog (cov hnab looj tes, tsom iav kev nyab xeeb, plua plav npog) thaum tuav. Nrog rau Daim Ntawv Qhia Kev Nyab Xeeb rau cov ntaub ntawv tshwj xeeb.
