Fluoro-K Tus Neeg Saib Xyuas: Kev Tiv Thaiv Hluav Taws Xob, vs Novec 1230, PFAS & Cov Ntaub Ntawv Kev Nyab Xeeb

 

 

Hauv thaj tsam ntawm kev tiv thaiv hluav taws,Fluoro-K tus neeg sawv cevtau tshwm sim los ua cov hluav taws huv huv -tus neeg tua hluav taws uas tsim los hloov cov laus, ib puag ncig kev puas tsuaj xws li halons thiab qee yam hydrofluorocarbons (HFCs). Raws li kev lag luam saib xyuas qhov tseem ceeb ntawm kev nyab xeeb, kev ua tau zoo, thiab kev ruaj khov, kev nkag siab Fluoro-K- suav nrog nws cov ntawv thov, kev cuam tshuam ib puag ncig, thiab kev qhia tshwj xeeb- ua qhov tseem ceeb. Kab lus no tshawb txog qhov tseem ceeb ntawm Fluoro-K, los ntawm nws lub luag haujlwm hauv kev tua hluav taws mus rau kev sib piv nrog cov khoom zoo sib xws, thiab cov ntsiab lus ntawm cov ntaub ntawv kev nyab xeeb.

 

Tau txais Fluoro-K tus neeg sawv cev MSDS Tam sim no

Fluoro-K tus neeg sawv cev, luv luv los ntawm fluoroketone, tshuaj hu ua perfluoro-2-methyl-3-pentanone (C₆F₁₂O, CAS No. 756-13-8), yog fluorinated ketone cais raws li "tus neeg saib xyuas huv" vim nws muaj peev xwm tua hluav taws, tsis muaj hluav taws kub hauv ib puag ncig. Nws yog ib feem ntawm tsev neeg ntawm lwm tiam hluav taws tua hluav taws uas tsim los kom sib npaug ntawm cov hluav taws kub-tawm kev ua haujlwm zoo nrog rau kev cuam tshuam ib puag ncig.

Kev lag luam, Fluoro-K feem ntau yog siv los ntawm lwm lub npe lag luam, suav nrog FK-5112, MH-5112, thiab Novec 1230 (ib lub cim lag luam ntawm 3M). Qhov kev sib tshooj no feem ntau ua rau muaj kev tsis sib haum xeeb, tab sis cov npe no txhua tus xa mus rau tib yam tshuaj lom neeg sib txawv tsuas yog los ntawm cov chaw tsim khoom sau npe.

Fluoro-K ua tau zoo hauv kev tua hluav taws vim muaj ob txoj kev ua haujlwm:

1. Kev nqus cua sov: Thaum tso tawm, nws sai vaporizes, nqus cov cua kub tseem ceeb ntawm qhov hluav taws kub, txo qhov kub thiab txias hauv qab qhov hluav taws kub ntawm cov roj.

2. Tshuaj inhibition: Nws cuam tshuam cov combustion saw cov tshuaj tiv thaiv los ntawm kev cuam tshuam nrog cov dawb radicals, halting nplaim propagation.

Qhov kev sib xyaw ua ke no ua rau nws muaj txiaj ntsig zoo tiv thaiv Class A (khoom siv roj), B (cov kua hluav taws xob), thiab C (hluav taws xob) hluav taws kub. Nws cov txiaj ntsig tseem ceeb hauv kev tua hluav taws muaj xws li:

 Tsis yog -conductivity:Muaj kev nyab xeeb rau siv nyob ib puag ncig cov cuab yeej hluav taws xob, cov chaw khaws ntaub ntawv, thiab chav tswj hwm.

 Tsawg toxicity:Thaum siv los ntawm cov lus pom zoo, nws ua rau muaj kev pheej hmoo tsawg rau tib neeg, tso cai rau "nyob thiab sib ntaus" raws tu qauv.

 Tsis muaj residue:Tso tseg tsis muaj kev puas tsuaj rau cov khoom siv hluav taws xob, tshuab, lossis cov khoom qub qub, txo cov nqi xa tawm - hluav taws kub.

Cov ntawv thov feem ntau suav nrog cov chav server, tsev cia puav pheej, chaw dav hlau, thiab cov txheej txheem kev lag luam uas ib txwm siv dej los yog ua npuas dej yuav ua rau muaj kev puas tsuaj ntxiv.

Cov lus nug nquag yog qhov txawv ntawm Fluoro-K thiab Novec 1230. Cov lus teb luv luv: tsis muaj tshuaj lom neeg sib txawv. Ob nqe lus hais txog perfluoro-2-methyl-3-pentanone; "Novec 1230" yog 3M lub npe, thaum "Fluoro-K" yog kev lag luam dav dav siv los ntawm lwm tus neeg muag khoom.

Thaum muab cov npe no sib piv, tsom mus rau cov qauv tsim khoom (xws li, qib purity) lossis cov tshuab xa khoom (xws li, khaws cia-siab vs. inert gas- cov thooj voos kheej kheej siab) muab los ntawm cov tuam txhab sib txawv, raws li cov khoom siv tshuaj tseem ceeb zoo ib yam.

Fluoro-K yog cais raws li PFAS (ib - thiab polyfluoroalkyl tshuaj), ib tsev neeg ntawm cov tshuaj uas paub txog lawv cov stability thiab dej/roj kuj. Txawm li cas los xij, tsis yog txhua tus PFAS sib npaug, thiab Fluoro-K sawv tawm rau nws qhov kev cuam tshuam ib puag ncig qis piv rau PFAS qub txeeg qub teg zoo li PFOA lossis PFOS:

Ozone Depletion Potential (ODP): 0, txhais tau tias nws tsis ua mob rau cov txheej txheem ozone.

Lub Ntiaj Teb Warming Potential (GWP): Tsawg (qhia ntawm ~ 1, raws li 100-xyoo suav), qis dua HFCs xws li HFC-227ea (GWP 3,220).

Lub neej hauv huab cua: luv luv (kwv yees li 5 hnub), txhais tau tias nws tawg sai sai hauv huab cua, txo qhov ntev - cov teebmeem huab cua.

Cov cwj pwm no ua rau Fluoro-K ua raws li cov kev cai thoob ntiaj teb xws li Montreal Protocol thiab Kigali Amendment, tso nws ua lwm txoj hauv kev rau cov laus laus.

Hauv qhov tseem ceeb, Fluoro-K yog qhov hloov pauv ncaj qha rau Novec 1230, muab PFAS- cov tshuaj dawb rau cov hluav taws tua hluav taws thaum tswj xyuas cov txiaj ntsig thiab kev nyab xeeb ntawm tus neeg sawv cev qub.

Rau kev nyab xeeb tuav, cia, thiab siv,Fluoro-K MSDS (Cov Ntaub Ntawv Kev Nyab Xeeb Cov Ntaub Ntawv)thiabFluoro-K Daim Ntawv Teev Npeyog cov peev txheej tseem ceeb. Cov ntaub ntawv no, raug yuam los ntawm cov qauv thoob ntiaj teb (xws li OSHA hauv Asmeskas, REACH hauv EU), suav nrog:

MSDS Cov ntsiab lus:

Tshuaj muaj pes tsawg leeg thiab kev phom sij (xws li, muaj peev xwm rau asphyxiation hauv qhov chaw kaw).

Kev pab thawj zaug (piv txwv li, kev tswj xyuas cov pa oxygen rau kev nqus pa).

Kev ceev faj txog kev tuav pov hwm (piv txwv li, cia ntawm qhov ntsuas kub kom tiv thaiv lub tog raj kheej tawg).

Cov ntaub ntawv ecological (piv txwv li, qib dej toxicity).

Daim Ntawv Teev Npe:

Lub cev muaj zog (qhov kub kub: ~ 49 degree; ceev: ~ 1.6 g / cm³).
Kev tua hluav taws ntau ntau: feem ntau 4-6% los ntawm ntim rau feem ntau cov roj).

Compatibility nrog cov ntaub ntawv (xws li, tsis yog -reactive nrog hlau, yas, los yog elastomers).
