Kub:Thov khaws nws rau hauv qhov chaw txias thiab qhuav kom deb ntawm kev tshav ntuj ncaj qha thiab cov khoom kub. Qhov tseeb, nws yuav tsum tau muab cia rau hauv chav tsev kub, tab sis yuav tsum tsis pub tshaj 25 ° C (77 ° F).
Qhov cua:Ua kom muaj cov chaw ntim khoom tau zoo kom txo qis kev sib txuam ntawm cov vapors.
Sau npe:Daim ntawv sau kom meej meej nrog lub npe tshuaj, kev xav, thiab tej yam kev ceeb toom kev phom sij los ua kom paub tseeb.
Sib cais:Khaws benzophenone deb ntawm cov ntaub ntawv tsis sib xws (xws li muaj zog oxidizing oxidizing cov neeg sawv cev) los tiv thaiv cov peev txheej.
Kev Ceev Fwm Kev Nyab Xeeb:Thaum tuav benzophenone, siv cov khoom tiv thaiv tus kheej tsim nyog (PPE) thiab xyuas kom meej cov ntaub ntawv nyab xeeb (SDS) muaj nyob rau hauv thaj chaw cia.
Benzophenone tau tsa cov kev txhawj xeeb txog kev noj qab haus huv, thiab nws cov peev xwm ntawm tib neeg yuav sib txawv raws li cov qib thiab tus kheej rhiab. Ntawm no yog qee cov ntsiab lus tseem ceeb txog nws kev nyab xeeb:
