mek kuab tshuaj lwm txoj
Methyl ethyl ketone (MEK, CAS No. 78-93-3), tseem hu ua 2-butanone hnyav, yog ib qho nquag siv nruab nrab-boiling ketone hnyav. Nws yog dav siv nyob rau hauv coatings, inks, adhesives, dewaxing agents, thiab electronics tu daim ntaub ntawv, ua methyl ethyl ketone MEK hnyav ib yam khoom tseem ceeb nyob rau hauv ntau yam kev lag luam. Vim nws qhov flammability thiab qee yam kev pheej hmoo rau kev noj qab haus huv, ntau lub lag luam nquag nrhiav MEK cov kuab tshuaj hloov. Kev xaiv cov kev hloov pauv yog nyob ntawm cov ntawv thov tshwj xeeb, xws li lub zog hnyav, tus nqi evaporation, cov khoom siv tau zoo, thiab cov qauv kev nyab xeeb, uas yog cov kev xav tseem ceeb thaum ntsuas kev siv methyl ethyl ketone.
Hauv qab no yog ob peb feem ntau siv hloov pauv rau methyl ethyl ketone (MEK) hauv kev siv:
Acetone (alternative rau MEK hnyav):
Acetone muaj qhov kub qis dua (kwv yees li 56 degree) thiab tus nqi evaporation sai dua, muaj peev xwm ua kom muaj zog. Txawm li cas los xij, nws yog ntau flammable thiab muaj ib tug ntse tsw. Nws yog qhov tsim nyog rau cov ntawv thov kom qhuav sai, xws li qee cov inks thiab cov nplaum, thiab feem ntau txiav txim siab thaum hloov MEK rau kev ntxuav lossis ceev - kho cov qauv.
Ethyl Acetate (MEK hloov rau txheej thiab inks):
Ethyl acetate muaj qhov kub ntawm 77 degree, ze rau ntawm MEK, nrog cov ntxhiab tsw qab thiab zoo solubility rau ntau cov resins. Nws yog feem ntau siv nyob rau hauv cov coatings thiab printing number case industries. Thaum nws cov toxicity qis dua cov tshuaj MEK methyl ethyl ketone, flammability tseem yuav tsum tau ua tib zoo tswj.
Methyl Isobutyl Ketone (MIBK) - qeeb -evaporating MEK lwm txoj:
MIBK muaj qhov kub siab dua (kwv yees li 116 degree) thiab qeeb evaporation. Nws muaj cov solubility zoo rau cov roj thiab cov resins thiab yog dav siv nyob rau hauv daim ntawv thov uas yuav tsum tau tswj kom qhuav, xws li high -coatings kawg thiab dewaxing agents, qhov twg methyl ethyl ketone MEK hnyav yuav evaporate sai heev.
Cyclhexanone (siab- boiling lwm txoj rau MEK):
Cyclohexanone muaj qhov kub ntawm ib ncig ntawm 155 degree, qeeb evaporation, thiab muaj zog solvency. Nws yog tshwj xeeb tshaj yog haum rau siab - cov khoom coatings thiab cov xim muaj xim. Txawm li cas los xij, nws muaj ntxhiab tsw zoo dua thiab tus nqi siab dua piv nrog cov methyl ethyl ketone siv hauv cov qauv tsim.
Vim li cas thiaj xaiv Gneebio ua koj tus neeg muag khoom?
Raws li ib tugTom ntej: methyl ethyl ketone (CAS 78-93-3)Chaw tsim tshuaj paus, Gneebio tsom rau cov khoom sib xws, kev siv tau zoo, thiab kev ntseeg siab ntawm cov khoom siv ntau. Lub tuam txhab ua haujlwm raws li kev tswj hwm nruj kom paub meej tiasmethyl ethyl ketone (MEK) ua tau raws li qhov yuav tsum tau muaj ntawm loj - nplai thiab qhov chaw tsim khoom tas mus li.
Qhov tseem ceeb ntawm kev tsim khoom thiab khoom siv zog muaj xws li:
- Tswj purity qib tsim nyog rau kev lag luam thiab khoom siv
- ruaj khov batch-rau-batch zoo rau ntev- kev yuav khoom
- Muaj peev xwm muab tau los txhawb kev cog lus thiab chaw xaj khoom
- Export -npaj ntim thiab cov ntaub ntawv (COA, SDS, thiab lwm yam)
