Iipropati zeMichiza:

I-Methyl ethyl ketone (MEK) lulwelo olungenambala olunevumba eliye lachazwa njengelibukhali ngokuphakathi, livumba elimnandi, i-peppermint, okanye i-acetone efana.Inyibilika emanzini ukuya kuthi ga kwi-28% ngobunzima kwaye iyadityaniswa nezinye izinyibilikisi ezininzi eziphilayo.Umda wokudubula osezantsi yi-1.4% kwaye umda ophezulu wokudubula yi-11.4%.I-Methyl ethyl ketone inokungahambelani ne-oxidizers eqinile, i-amines, i-ammonia, i-inorganic acids, i-caustics, i-isocyanates, kunye ne-pyridines.Xa isetyenziswa kwimizi-mveliso, i-methyl ethyl ketone kufuneka iphathwe ngononophelo, njengoko ilulwelo olunokutsha lwe-NIOSH yodidi lwe-lB.

Isicelo:

I-Methyl ethyl ketone (i-2-butanone, i-ethyl methyl ketone, i-methyl acetone) i-solvent ye-organic ye-toxicity ephantsi, efumaneka kwizicelo ezininzi.Isetyenziswa kwiimveliso zoshishino kunye nezorhwebo njenge-solvent ye-adhesives, iipeyinti, kunye nee-agent zokucoca kunye ne-solvent de-waxing.Inxalenye yendalo yokunye ukutya, i-methyl ethyl ketone inokukhutshwa kwindawo engqongileyo ngeentaba-mlilo kunye nomlilo wehlathi. Isetyenziselwa ukwenziwa komgubo ongenomsi kunye ne-synthetic resins engenambala, njenge-solvent, kunye ne-insurface coating.Ikwasetyenziswa njengencasa yencasa ekutyeni.

I-MEK isetyenziselwa ukunyibilikisa kwiinkqubo ezahlukeneyo zokugquma, umzekelo, i-vinyl, i-adhesives, i-nitrocellulose, kunye neengubo ze-acrylic.Isetyenziselwa ukususa ipeyinti, i-lacquers, ivanishi, iipeyinti zokutshiza, izitywini, iglue, iiteyiphu zemagneti, ii-inki zokuprinta, iireyini, iirosin, izisombululo zokucoca, kunye nepolymerization.Ifumaneka kwezinye iimveliso zabathengi, umzekelo, iisamente zendlu kunye nezinto zokuzilibazisa, kunye neemveliso zokuzalisa iinkuni.I-MEK isetyenziselwa ukuthambisa ioyile yokuthambisa, ukuthotywa kwesinyithi, kwimveliso yesikhumba sokwenziwa, iphepha elicacileyo kunye nefoyile ye-aluminium, kwaye njengekhemikhali ephakathi kunye ne-catalyst.Sisinyibilikisi esikhuphayo ekusetyenzweni kokutya kunye nezithako zokutya.I-MEK inokusetyenziselwa ukuvala inzala kwizixhobo zotyando kunye nezixhobo zamazinyo.
Ukongeza ekwenziweni kwayo, imithombo yokusingqongileyo ye-MEK ibandakanya ukukhupha ijethi kunye neenjini zokutsha zangaphakathi, kunye nemisebenzi yefektri efana nokufakwa kwegesi yamalahle.Ifumaneka kwisixa esikhulu kumsi wecuba.I-MEK iveliswa ngokwebhayoloji kwaye ichongiwe njengemveliso ye-microbial metabolism.Kwakhona kufunyenwe kwizityalo, i-pheromones yezinambuzane, kunye nezicubu zezilwanyana, kwaye i-MEK mhlawumbi imveliso encinci ye-metabolism ye-mammalian eqhelekileyo.Izinzile phantsi kweemeko eziqhelekileyo kodwa inokwenza iiperoxides ekugcinweni ixesha elide;ezi zinokugqabhuka.
