Cov kev lag luam twg siv PERC Perchlorethylene (CAS 127-18-4)?

Perc Perchlorethylene tseem hu ua PCE lossis tetrachloroethylene. Nws yog xim tsis muaj xim, tsis yog - cov kua hluav taws xob uas yog siv rau cov hlau degreasing xws li nres, cav, thiab xaim. Nws yog siv nyob rau hauv industrial chaw thiab kuj rau tu fabrics.

Dab tsi yog Cov Khoom Ntawm Perc Perchlorethylene?

CAS 127-18-4 Nryog ib qho tsis muaj xim, pob tshab kua uas muaj cov tshuaj chlorine muaj zog.

1. Solubility: Perchlorethylene yog soluble nyob rau hauv ntau cov organic solvents, xws li ethanol, ethers, thiab hydrocarbons, tab sis nws solubility kuj tsawg.

2. Chemical Stability: Tetrachlorethylene kuj ruaj khov ntawm chav tsev kub thiab tsis hnov ​​​​mob nrog cov tshuaj feem ntau. Txawm li cas los xij, nws yuav decompose los yog hlawv nyob rau hauv qhov kub thiab txias, ncaj qha tshav ntuj, thiab muaj zog oxidizing tus neeg sawv cev.

3. Toxicity: PERC/PCE muaj qee yam toxicity thiab tuaj yeem nkag mus rau tib neeg lub cev los ntawm kev nqus pa, sib chwv ntawm daim tawv nqaij, lossis kev noj, ua rau muaj kev puas tsuaj rau lub ntsws, lub siab, thiab lub hauv paus paj hlwb.

Cov kev lag luam twg siv PERC Perchlorethylene (CAS 127-18-4)?

Kev lag luam uas siv perchlorethylene (PERC) suav nrog kev ntxuav qhuav thiab ntxhua khaub ncaws, kev tsim tshuaj lom neeg, thiab hlau degreasing.

1. Qhuav Ntxuav:Nws txoj kev siv nto moo tshaj plaws yog siv los ntxuav cov ntaub, vim nws tshem tawm cov roj thiab cov roj yam tsis muaj kev puas tsuaj rau textiles.
2. Hlau Degreasing: PERCyog feem ntau siv los ntxuav thiab degrease hlau qhov chaw hauv kev tsim khoom.
3. Chemical Intermediate: Perchlorethylene (CAS 127-18-4)ua cov khoom siv raw (feedstock) hauv kev tsim khoom ntawm lwm cov tshuaj, tshwj xeeb tshaj yog hydrofluorocarbon (HFC) tub yees.
4. Lwm yam kev siv:PCE tau siv rau hauv cov xim tshem tawm, luam ntawv inks, thiab aerosol formulations.

txog peb

Henan Gneebiotau tsim nyob rau hauv 2016, ua raws li lub tswv yim ntawm "cov khoom siv tshuaj lom neeg thoob ntiaj teb" thiab tsom mus rau qib siab -kev lag luam tshuaj lom neeg zoo. Lub tuam txhab feem ntau cuam tshuam cov khoom siv tshuaj lom neeg, xws li dichloromethane; methyl sulfoxide DMSO ( qib kev lag luam thiab kws tshuaj); ethylene glycol (MEG); p-Xylene, thiab lwm yam.

Tag nrho peb cov khoom siv tshuaj lom neeg tau txais cov ntawv pov thawj thoob ntiaj teb suav nrog REACH, ISO, FMQS, HALAL, thiab Halal ntawv pov thawj, kom ntseeg tau tias muaj txiaj ntsig zoo thiab kev lees paub thoob ntiaj teb, Peb muaj cov tsev khaws khoom hauv coreports xws li Qingdao, Tianiin, thiab Shanghai, nrog rau 15-hnub kev xa khoom xa tuaj.
