Ibikoresho bya Shimi:

Methyl Ethyl ketone ni ifumbire mvaruganda hamwe na formula ya chimique CH3COCH2CH3 nuburemere bwa molekile ya 72.11. Nibintu bitagira ibara kandi bisobanutse bifite impumuro isa na acetone. Biroroshye guhindagurika. Ntibisanzwe hamwe na Ethanol, ether, benzene, chloroform namavuta. Gushonga mubice 4 byamazi, ariko gukomera kugabanuka mugihe ubushyuhe bwiyongereye, kandi birashobora gukora imvange ya azeotropique namazi. Uburozi buke, LD50 (imbeba, umunwa) 3300mg / kg. yaka, imyuka irashobora gukora imvange iturika hamwe numwuka. Ubwinshi bwumwuka wumuyaga ufite imiterere ya anesthetic.

Gusaba:

Methyl etyl ketone (2-butanone, Ethyl methyl ketone, methyl acetone) ni umusemburo wa organic wuburozi buke ugereranije, buboneka mubikorwa byinshi. Ikoreshwa mubicuruzwa byubucuruzi nubucuruzi nkigishishwa cyamavuta, amarangi, hamwe nogukora isuku kandi nkigishishwa cya de-shashara. Ikintu gisanzwe cyibiribwa bimwe na bimwe, methyl ethyl ketone irashobora kurekurwa mubidukikije nibirunga numuriro wamashyamba.Bikoreshwa mugukora ifu itagira umwotsi hamwe nubutaka butagira ibara, nkibishishwa, kandi bitwikiriye. Ikoreshwa kandi nka flavoursubstance mu biryo.

MEK ikoreshwa nk'umuti wa sisitemu zitandukanye zo gutwikira, urugero, vinyl, ibifata, nitrocellulose, hamwe na acrylic. Ikoreshwa mugukuraho amarangi, lacquers, langi, gusiga amarangi, kashe, kole, kaseti ya magneti, wino yo gucapa, resin, rozine, ibisubizo byogusukura, hamwe na polymerisation. Iboneka mubindi bicuruzwa byabaguzi, kurugero, urugo na sima zishimisha, nibicuruzwa byuzuza ibiti. MEK ikoreshwa mu gusiga amavuta yo gusiga, kwangirika kwibyuma, mugukora uruhu rwubukorikori, impapuro zibonerana hamwe na fayili ya aluminiyumu, kandi nkimiti hagati na catalizike. Numuti ukuramo mugutunganya ibiribwa nibiribwa. MEK irashobora kandi gukoreshwa muguhagarika ibikoresho byo kubaga no kuvura amenyo.
Usibye kuyikora, amasoko y’ibidukikije ya MEK arimo umwuka uva mu ndege na moteri yaka imbere, hamwe n’ibikorwa by’inganda nka gaze y’amakara. Biboneka ku bwinshi mu mwotsi w'itabi. MEK ikorwa mubinyabuzima kandi yamenyekanye nkigicuruzwa cya mikorobe. Yabonetse kandi mu bimera, feromone y’udukoko, no mu nyama z’inyamaswa, kandi MEK birashoboka ko ari umusaruro muto w’inyamabere zisanzwe z’inyamabere. Irahagaze mubihe bisanzwe ariko irashobora gukora peroxide kubikwa igihe kirekire; ibi birashobora guturika.
