B-diketone

Feem ntau cov hlau ions ncaj qha tsim kev sib koom ua ke nrog -diones nyob rau hauv qhov tsim nyog. Feem ntau yog yaj hauv cov kuab tshuaj organic. Yog ib yam tseem ceeb ntawm cov tshuaj reagents, yog ntau yam tshuaj (xws li dinitrogen complexes, hlau-organic, thiab lwm yam). Synthetic thiab hlau zaj duab xis deposition precursors yuav siv tau raws li catalysts rau ntau yam tshuaj (xws li butadiene polymerization).
Kuj tseem siv rau kev sib cais tsis tshua muaj ntiaj teb. Qee cov ntaub ntawv siv lead ua kua, qee qhov yog cov khoom siv kho qhov muag tsis zoo, thiab qee qhov -ketone tsawg lub ntiaj teb complexes yog cov khoom siv luminescent, uas yog qhov tseem ceeb hauv kev kawm txog cov khoom siv nrog cov khoom siv kho qhov muag, hluav taws xob thiab hlau nplaum.
Cov nyhuv yog raws li nram no
Siv los ua PVC-pab thermal stabilizer
Raws li kev sib koom ua ke rau calcium / zinc hydroxylate stabilization system, nws yog siv los tsim cov dej ntxhia hauv fwj, roj chim, daim ntawv pob tshab thiab pob tshab zaj duab xis, thiab lwm yam .; PVC thermal stabilizer
Cov khoom no muaj ib qho kev nqus ntawm ultraviolet lub teeb muaj nuj nqi, rau cov khoom muaj peev xwm muab kev ruaj ntseg mus ntev, thiab tsis muaj tshuaj lom tsis muaj stimulation, siv los tiv thaiv cov tawv nqaij los ntawm tshav kub kub tshuaj pleev thaiv hnub, daim tawv nqaij cream.
