Daim ntawv thov
1. 3-Fluorophthalic anhydride feem ntau yog siv los ua ib qho tseem ceeb nruab nrab ntawm kev sib txuas ntawm cov polymers siab heev, xws li fluorinated polyimides thiab epoxy resins.
2. 3-Fluorophthalic anhydride CAS 652-39-1 ua lub tsev thaiv rau cov tshuaj, agrochemicals, thiab tshwj xeeb dyes lossis pigments.
3. Cov khoom siv no kuj tseem siv rau hauv cov ntaub ntawv tshawb fawb txog kev tsim kho siab -kev ua tau zoo, cua sov- cov ntaub ntawv tiv taus uas tsis tshua muaj dielectric.
Cia thiab ceev faj
1. Khaws 3-fluorophthalic anhydride nyob rau hauv ib qho chaw txias, qhuav, zoo-ventilated qhov chaw, tiv thaiv los ntawm noo noo thiab deb ntawm tshav kub.
2. Khaws lub thawv kaw kom nruj thiab sib cais los ntawm cov khoom muaj zog oxidizing, muaj zog hauv paus, cawv, thiab amines.
3. Kov 3-Fluorophthalic anhydride CAS 652-39-1 nrog cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE), nrog rau cov hnab looj tes tiv thaiv tshuaj, tsom iav kev nyab xeeb, thiab lub ntsej muag plua plav, tiv thaiv kev sib cuag thiab nqus plua plav lossis vapors.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm ntawm qhov chaw nchuav, ua kom qhov cua, thiab hnav cov khoom tiv thaiv tsim nyog ( hnab looj tes, tsom iav, khaub ncaws tiv thaiv, lub tshuab ua pa yog tias muaj plua plav).
2. Ua tib zoo 3-Fluorophthalic anhydride CAS 652-39-1 sau cov khoom spilled nrog cov cuab yeej huv, qhuav. Tsis txhob tsim cov plua plav. Muab cov khoom tsis huv tso rau hauv ib lub thawv ntim khoom kaw, uas muaj cov ntawv pov tseg rau kev pov tseg pov tseg.
3. Tiv thaiv cov khoom los ntawm kev nkag mus rau hauv qhov dej los yog ib puag ncig. Ntxuav thaj chaw muaj kev cuam tshuam nrog dej thiab tshuaj ntxuav tes, sau cov ntxhua khaub ncaws kom raug. Neutralize residuals ceev faj yog tias xav tau.
Cov ntaub ntawv kev nyab xeeb
1. 3-Fluorophthalic anhydride muaj teeb meem yog tias nqos, nqus tau plua plav, lossis tiv nrog daim tawv nqaij. Nws ua rau tawv nqaij kub hnyiab heev, qhov muag puas, thiab ua pa ua pa . 3-Fluorophthalic anhydride CAS 652-39-1 yog corrosive thiab noo noo-rhiab heev.
2. Nws tuaj yeem hlawv tau ntawm qhov kub thiab txias thiab tuaj yeem decompose los tsim cov pa phem thiab corrosive (hydrogen fluoride, phthalic anhydride derivatives).
3. Nco ntsoov sab laj nrog 3-fluorophthalic anhydride Safety Data Sheet (SDS) kom paub meej txog kev phom sij, tuav, thiab cov ntaub ntawv tswj hwm.
