Cia thiab ceev faj
1. Khaws Tannic acid nyob rau hauv lub thawv kaw nruj nreem nyob rau hauv ib qho chaw txias, qhuav, thiab qhov chaw zoo - qhov cua, tiv thaiv los ntawm lub teeb thiab huab cua, vim nws yog rhiab heev rau ob qho tib si thiab nws cov xim darkens thaum raug. Pom zoo cia tej yam kev mob muaj xws li chav tsev kub (15-30 degree); Txawm li cas los xij, kev ruaj ntseg mus ntev rau cov ntaub ntawv hmoov tuaj yeem khaws cia ntawm -20℃txog li 3 xyoos.
2. Khaws Tannic acid kom deb ntawm cov muaj zog oxidizing cov neeg ua haujlwm thiab cov hauv paus muaj zog vim tsis sib haum, thiab tsis txhob sib cuag nrog hlau thiab lwm yam hlau hnyav, raws li Tannic acid CAS 1401-55-4 cov ntaub ntawv muaj xim zoo nkauj. Nws kuj yog rhiab heev rau cov dej noo thiab yuav tsum tau khaws cia rau hauv qhov chaw qhuav.
3. Ib txwm siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE), nrog rau cov hnab looj tes tiv thaiv thiab tiv thaiv qhov muag (ntxuav lub tsom iav kom ruaj ntseg), thaum tuav Tannic acid kom tsis txhob muaj tawv nqaij, qhov muag, thiab ua pa. Xyuas kom muaj qhov cua txaus hauv qhov chaw tuav thiab tsis txhob muaj plua plav.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd muaj cov Tannic acid spill siv inert, tsis yog -cov khoom siv hluav taws xob (xws li, xuab zeb) thiab tso cov khoom khaws cia rau hauv lub thawv ntim khoom ntim, sau cov tshuaj khib nyiab. Zam kom tsis txhob muaj plua plav thiab siv tsis yog- cov cuab yeej hluav taws xob rau kev ntxuav.
2. Tiv thaiv Tannic acid los ntawm kev nkag mus rau hauv cov dej ntws los yog cov dej, raws li kev tawm mus rau ib puag ncig yuav tsum zam. Tom qab khaws cov khoom, ntxuav qhov chaw nchuav kom huv si.
3. Cov neeg ua haujlwm Tannic acid CAS 1401-55-4 yuav tsum hnav PPE haum, nrog rau cov hnab looj tes tiv thaiv thiab tiv thaiv qhov muag, thaum ntxuav. Pov tseg Tannic acid thiab tag nrho cov khoom tsis huv raws li cov cai hauv zos, xeev, thiab tseem fwv ib puag ncig; tswj incineration yog ib qho kev xaiv rau kev pov tseg.
Cov ntaub ntawv kev nyab xeeb
1. Tannic acid yog cais nrog GHS teeb liab lo lus "Ceeb toom" thiab tej zaum yuav muaj teeb meem yog tias nqos tau (H303, Qeb 5), nrog rau qhov ncauj LD50 ntawm 2260 mg/kg hauv nas. Tannic acid CAS 1401-55-4 tuaj yeem ua rau xeev siab thiab mob plab thaum raug mob.
2. Tannic acid yog cov khoom siv hluav taws xob nrog lub teeb nyem ntawm kwv yees li 198-199℃thiab autoignition kub ntawm 526-527 degree. Thaum rhuab mus rau decomposition, nws yuav emit toxic fumes. Tannic acid CAS 1401-55-4 yog suav tias yog ruaj khov tab sis tsis sib haum nrog cov oxidizing muaj zog thiab cov hauv paus.
3. Tannic acid yog cais raws li IARC Pawg 3 carcinogen (tsis cais raws li nws cov carcinogenicity rau tib neeg). Txawm hais tias nws muaj kev mob toxicity tsawg, ntau qhov ntau yuav ua rau ntuav, mob plab, thiab raws plab, thiab nws yog siv rau R&D nkaus xwb, tsis yog siv rau tshuaj, tsev neeg, lossis lwm yam kev siv. Nco ntsoov sab laj nrog Daim Ntawv Qhia Kev Nyab Xeeb tshwj xeeb (SDS) kom muaj kev phom sij tag nrho, ua ntej - pab, thiab tuav cov ntaub ntawv .
