Puas yog acetonitrile Acn tshuaj yaj cov yas?
CAS 75-05-8 Acetoniayog nruab nrab kom tsis sib haum nrog ntau yam plastics. Thaum nws tsis yog universal hnyav rau tag nrho cov yas, nws tuaj yeem ua puas lossis yaj qee qhov.
Plastics kom tsis txhob: Acetonitrile Acn yooj yim yaj los yog hnyav heev ua rau polystyrene (PS), poly (methyl methacrylate) (PMMA, los yog acrylic) thiab ntau lwm yam styrene -raws li plastics. Nws kuj cuam tshuam rau qee hom polycarbonate (PC).
Cov khoom siv tau zoo (rau kev siv ib ntus): Polypropylene (PP) thiab siab - ntom polyethylene (HDPE) feem ntau muaj luv luv - lub sij hawm tsis kam. Polytetrafluoroethylene (PTFE los yog Teflon®) yog qhov tseem ceeb inert.
Kev xyaum zoo tshaj plaws: Nco ntsoov xyuas daim ntawv qhia txog tshuaj lom neeg ua ntej siv ACN nrog cov thawv yas, tubing lossis foob. Rau kev sim siv, tus qauv yog iav nrog PTFE seals lossis tshwj xeeb HPLC - qib hnyav fwj.
