Siv qhov cua kom txaus thiab txo cov plua plav tawm.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais qhov chaw nchuav thiab ua kom muaj cua txaus. Muaj 1,5-Diphenylcarbazide siv cov khoom siv qhuav, inert, tsis-combustible absorbent, zam plua plav tsim, thiab tiv thaiv kev nkag mus rau hauv cov dej los yog cov dej.
2. Ua tib zoo cheb 1 5-Diphenylcarbazide CAS 140-22-7 siv cov cuab yeej huv, tsis muaj hluav taws xob lossis lub tshuab nqus tsev / cheb cov khoom rau hauv cov thawv pov tseg uas tsim nyog. Rau me me spills / leaks, cheb thiab tso rau hauv lub thawv tsim nyog rau kev pov tseg.
3. Cov neeg ua haujlwm yuav tsum hnav PPE tsim nyog suav nrog tshuaj lom neeg- cov hnab looj tes tiv thaiv thiab tiv thaiv qhov muag thaum ntxuav. 1,5-Diphenylcarbazide tsis raug tswj raws li cov khoom phom sij rau kev thauj los ntawm qee cov kev cai (DOT).
Cov ntaub ntawv kev nyab xeeb
1. 1,5-Diphenylcarbazide yog cais nrog GHS teeb liab lo lus "Tseeb". Nws ua rau tawv nqaij khaus (H315), mob qhov muag loj (H319), thiab tej zaum yuav ua rau mob ua pa (H335).
2. 1,5-Diphenylcarbazide muaj teeb meem yog tias nqos tau thiab tuaj yeem nqus tau los ntawm daim tawv nqaij hauv qhov teeb meem ntau npaum li cas . 1 5-Diphenylcarbazide CAS 140-22-7 yog qhov ruaj khov nyob rau hauv ib txwm muaj tab sis decomposes thaum cua sov, tsim cov pa phem thiab ua rau khaus nrog rau nitrogen oxides, carbon monoxide, thiab carbon dioxide. NFPA kev ntsuam xyuas kev noj qab haus huv yog 2 (mob txaus ntshai), flammability 1, thiab instability 0.
3. 1,5-Diphenylcarbazide muaj qhov melting point ntawm 170-177℃. Nws yog soluble hauv glacial acetic acid, cawv, thiab acetone, thiab me ntsis soluble hauv dej. Nco ntsoov sab laj rau Daim Ntawv Qhia Txog Kev Nyab Xeeb tshwj xeeb (SDS) kom tiav cov ntaub ntawv txaus ntshai thiab cov txheej txheem pab thawj zaug (P305+P351+P338 rau qhov muag, P302+P352 rau daim tawv nqaij, P304+P340 rau kev nqus pa).
