Daim ntawv thov sib txawv
MEK (Methyl Ethyl Ketone):
- Industrial Solvent: Siv dav hauv txheej txheej, inks, adhesives, lubricant dewaxing, thiab photolithography developers nyob rau hauv kev lag luam electronics vim nws muaj zog solvency thiab nruab nrab evaporation tus nqi. cov
- Chemical Intermediate:Methyl ethyl ketone hnyavyog siv nyob rau hauv cov synthesis ntawm cov tshuaj zoo xws li tshuaj thiab tshuaj tsw qab. cov
ACE (Acetone):
- General-lub hom phiaj hnyav: Ib qho ntawm cov kuab tshuaj feem ntau siv los ntxuav, degreasing, pleev xim rau, tshem tawm cov ntsia thawv polish, thiab lwm yam.
- Laboratory:ACE (Acetone)yog nquag siv los ntxuav cov iav thiab cov qauv npaj.
- Cov khoom siv raw: ACE yog siv los tsim cov methyl methacrylate (acrylic iav), bisphenol A, thiab lwm yam.
xaus
MEK muaj zog solvency nrog ceev evaporation zog. Cov ntawv thov suav nrog - acrylic txheej cov kuab tshuaj, tshuaj ntxuav cov kua dej, number case & xim hnyav, thiab yas lacquers. MEK yog tus neeg saib xyuas muaj zog dua li Acetone vim tias nws muaj qhov qis dua evaporation thiab boils ntawm qhov kub siab dua.
