Chemical Properties:

Methyl ethyl ketone (MEK) ndi madzi opanda mtundu okhala ndi fungo lomwe limanenedwa kuti ndi lakuthwa pang'ono, lonunkhira bwino, peppermint, kapena acetone ngati.Imasungunuka m'madzi mpaka 28% kulemera kwake ndipo imasakanikirana ndi zosungunulira zina zambiri.Malire apansi ophulika ndi 1.4% ndipo malire apamwamba ndi 11.4%.Methyl ethyl ketone ikhoza kukhala yosagwirizana ndi oxidizer amphamvu, amines, ammonia, inorganic acids, caustics, isocyanates, ndi pyridines.Mukagwiritsidwa ntchito m'mafakitale, methyl ethyl ketone iyenera kusamaliridwa mosamala, chifukwa ndi Class lB yamadzi yoyaka moto ya NIOSH.

Ntchito:

Methyl ethyl ketone (2-butanone, ethyl methyl ketone, methyl acetone) ndi organic zosungunulira wa kawopsedwe otsika, amene amapezeka ntchito zambiri.Amagwiritsidwa ntchito m'mafakitale ndi malonda monga zosungunulira zomatira, utoto, ndi zoyeretsa komanso ngati zosungunulira zosungunulira.Chigawo chachilengedwe cha zakudya zina, methyl ethyl ketone imatha kutulutsidwa m'chilengedwe ndi mapiri ndi moto wa nkhalango. Amagwiritsidwa ntchito popanga ufa wopanda utsi ndi utomoni wopanda utoto, monga zosungunulira, ndi zokutira zamkati.Amagwiritsidwanso ntchito ngati chokometsera m'zakudya.

MEK imagwiritsidwa ntchito ngati chosungunulira pamakina osiyanasiyana okutira, mwachitsanzo, vinyl, zomatira, nitrocellulose, ndi zokutira za acrylic.Amagwiritsidwa ntchito pochotsa utoto, ma lacquers, ma varnish, utoto wopopera, zosindikizira, zomatira, matepi a maginito, inki zosindikizira, ma resin, ma rosin, zotsukira, komanso polima.Amapezeka muzinthu zina zogula, mwachitsanzo, simenti zapakhomo ndi zosangalatsa, ndi zinthu zodzaza matabwa.MEK ntchito dewaxing mafuta mafuta, degreasing zitsulo, kupanga kupanga zikopa, mandala pepala ndi zojambulazo aluminiyamu, ndi monga mankhwala wapakatikati ndi chothandizira.Ndi zosungunulira m'zigawo pokonza zakudya ndi zosakaniza chakudya.MEK itha kugwiritsidwanso ntchito kutsekereza zida za opaleshoni ndi zamano.
Kuphatikiza pakupanga kwake, gwero lachilengedwe la MEK limaphatikizapo utsi wochokera ku injini zoyatsira zamkati, ndi zochitika zamafakitale monga kutulutsa malasha.Amapezeka mu utsi wochuluka wa fodya.MEK imapangidwa mwachilengedwe ndipo yadziwika kuti idapangidwa ndi tizilombo toyambitsa matenda.Zapezekanso muzomera, ma pheromones a tizilombo, ndi minyewa ya nyama, ndipo MEK mwina ndi chinthu chaching'ono cha metabolism yachibadwa ya mammalian.Imakhala yokhazikika pansi pazikhalidwe wamba koma imatha kupanga peroxides pakusungidwa kwanthawi yayitali;izi zitha kukhala zophulika.
