Hauv kev tsim cov Mg thiab Mg alloys; nyob rau hauv brightening ntawm Al; rau purifying thiab cleansing ntau qhov chaw ntawm npias-dispensing apparatus, hlab, thiab lwm yam., sterilizing mis nyuj thiab lwm yam khoom noj khoom haus; nyob rau hauv iav thiab porcelain kev lag luam; raws li mordant rau aluminium; raws li "qaub" hauv daim ntaub ntxhua khaub ncaws. Hauv kev tsim khoom ntawm HF. |
| Kev piav qhia dav dav |
Ammonium bifluoride tov yog cov dawb crystalline khoom yaj hauv dej. Ammonium hydrogen difluoride yog corrosive rau hlau thiab ntaub so ntswg. Ammonium hydrogen difluoride yog siv rau hauv ceramics. |
| Cua & Dej Reactions |
Dissolute hauv dej thiab tsim cov tshuaj tsis muaj zog ntawm hydrofluoric acid. |
| Reactivity Profile |
AMMONIUM BIFLUORIDE reacts hnyav nrog cov hauv paus. Nyob rau hauv lub xub ntiag ntawm noo noo yuav corrode iav, cement, thiab feem ntau hlau. Flammable hydrogen gas tuaj yeem sau rau hauv qhov chaw kaw. Tsis txhob siv steel, npib tsib xee, lossis txhuas ntim [USCG, 1999]. |
| Hazard |
Corrosive rau daim tawv nqaij. |
| Health Hazard |
TOXIC; nqus tau, noj los yog tawv nqaij ntawm cov khoom yuav ua rau mob hnyav lossis tuag taus. Kev sib cuag nrog cov khoom molten yuav ua rau mob hnyav rau ntawm daim tawv nqaij thiab qhov muag. Tsis txhob sib cuag ntawm daim tawv nqaij. Cov teebmeem ntawm kev sib cuag lossis nqus pa tuaj yeem ncua sijhawm. Hluav taws yuav ua rau khaus, corrosive thiab/los yog cov pa phem. Cov dej ntws los ntawm kev tswj hluav taws los yog cov dej dilution tuaj yeem ua rau corrosive thiab / los yog tshuaj lom thiab ua rau muaj kuab paug. |
| Hluav Taws Xob |
Tsis-combustible, tshuaj nws tus kheej tsis hlawv tab sis yuav decompose raws li cua sov los tsim corrosive thiab/los yog tshuaj lom pa taws. Ib txhia yog oxidizers thiab tej zaum yuav ignite combustibles (ntoo, ntawv, roj, khaub ncaws, thiab lwm yam). Kev sib cuag nrog cov hlau tuaj yeem hloov pauv cov pa hluav taws xob hydrogen. Cov thawv ntim khoom tuaj yeem tawg thaum cua sov. |
| Flammability thiab Explosibility |
Tsis yog nplaim taws |
| Kev ruaj ntseg Profile |
Caustic tshuaj lom thiab muaj zog irritant los ntawm txhua txoj kev. Saib kuj HYDROFLUORIC ACID. Thaum rhuab mus rau decomposition nws emits cov pa phem heev ntawm F-, TSIS, thiab NH3. |
| Ntxim yuav nphav raug |
Nws yog siv los ua kom tsis muaj menyuam, hauv cov khoom noj siv mis thiab brewery; nyob rau hauv ceramic, iav, thiab electroplating industries; raws li khaub ncaws qaub. |
| Kev xa khoom |
Muab cov pa oxygen yog ua pa nyuaj. Tshem tawm thiab cais cov khaub ncaws thiab khau uas tsis huv. Nyob rau hauv cov ntaub ntawv ntawm kev sib cuag nrog cov khoom, tam sim ntawd yaug daim tawv nqaij los yog ob lub qhov muag nrog dej ntws li 20 feeb. Rau kev sib cuag ntawm daim tawv nqaij me, tsis txhob kis cov khoom ntawm cov tawv nqaij tsis zoo. Cia tus neeg raug tsim txom sov thiab nyob ntsiag to. Kev cuam tshuam ntawm kev raug (inhalation, ingestion, los yog daim tawv nqaij sib cuag) rau cov khoom yuav ncua. Xyuas kom cov neeg ua haujlwm kho mob paub txog cov khoom (cov) koom nrog thiab ceev faj tiv thaiv lawv tus kheej. Kev soj ntsuam kev kho mob raug pom zoo rau 24 mus rau 48 teev tom qab ua pa ntau dhau, vim tias mob ntsws edema yuav qeeb. Raws li kev pabcuam thawj zaug rau pulmonary edema, tus kws kho mob lossis kws kho mob tau tso cai yuav txiav txim siab muab tshuaj lossis lwm yam kev nqus pa. |
| Kev tsis sib haum xeeb |
Tsis sib haum nrog oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, thiab lwm yam); kev sib cuag tej zaum yuav ua rau hluav taws kub los yog tawg. Khaws kom deb ntawm cov ntaub ntawv alkaline, muaj zog hauv paus, muaj zog acids, oxoacids, epoxides. Nyob rau hauv lub xub ntiag ntawm noo noo corrodes pob zeb, hlau, iav. |
| Pov tseg pov tseg |
Tej zaum yuav muab faus rau hauv ib qho chaw tshwj xeeb uas muaj tshuaj lom neeg pov tseg. Cov dej khib nyiab tuaj yeem tshwm sim nrog cov kua qaub ntau dhau los ntawm kev lag luam thiab rov qab los yog pov tseg av ntawm cov calcium fluoride sib cais. |
