Raws li txoj cai dav dav, acetone yog cov khoom lag luam thiab tseem ceeb tshaj plaws los ntawm distillation ntawm thee. Yav dhau los, nws yog tsuas yog siv los ua cov khoom siv raw rau ua cov cellulose acetate, polyester thiab lwm cov polymers. Nyob rau hauv xyoo tsis ntev los no, nrog kev txhim kho kev thev naus laus zis thiab kev hloov ntawm Raw Khoom Siv Khoom Siv, kev siv acetone kuj tau txuas ntxiv mus. Ntxiv rau kev siv cov khoom siv raw rau kev tsim cov khoom polymers, nws kuj tseem siv tau ua qhov kev ua tau zoo ntawm cov kuab tshuaj thiab tu tus neeg saib xyuas.
Ua ntej tshaj plaws, los ntawm cov kev pom ntawm kev tsim khoom, cov khoom siv rau kev ua cov acetone yog thee, roj thiab nkev. Hauv Suav teb, thee yog cov khoom siv tseem ceeb rau kev ua cov acetone. Cov txheej txheem ntau lawm ntawm acetone yog kom distillate thee kom muaj cov cua sov thiab cov kev mob siab, extract thiab ua kom zoo dua cov khoom lag luam tom qab sib tov.
Thib ob, los ntawm kev pom ntawm daim ntawv thov, Acetone yog dav siv nyob rau hauv cov teb ntawm cov tshuaj, duyestuffs, textiles, luam ntawv thiab lwm yam lag luam. Hauv kev kho mob teb, acetone feem ntau yog siv los ua cov kuab tshuaj rau kev rho tawm cov khoom xyaw los ntawm cov nroj tsuag thiab tsiaj txhu. Nyob rau hauv cov dyestuffs thiab textiles, acetone yog siv los ua ib tug neeg tu tus neeg sawv cev kom tshem tawm roj thiab siv quav ciab ntawm cov ntaub. Hauv kev luam ntawv, Acetone yog siv los yaj cov ntawv luam tawm thiab tshem tawm roj thiab siv quav ciab ntawm cov ntawv luam tawm.
Thaum kawg, los ntawm kev pom kev xav ua lag luam xav tau, nrog kev txhim kho ntawm Tuam Tshoj kev lag luam thiab kev hloov ntawm Raw Khoom Siv Khoom Siv, qhov kev thov rau acetone yog tas li nce. Ntawm tam sim no, Tuam Tshoj qhov kev thov rau Acetone qib ua ntej hauv ntiaj teb, muaj npe rau ntau tshaj 50% ntawm tag nrho cov thoob ntiaj teb. Cov laj thawj tseem ceeb yog Tuam Tshoj muaj cov peev nyiaj ntawm cov thee thiab kev thov loj rau kev thauj mus los thiab kev tsim kho.
Txhawm rau suav, acetone yog cov khoom siv tsis tseem ceeb. Hauv Suav teb, vim nws cov kev nplua nuj ntawm cov neeg nplua nuj rau cov neeg polymers hauv ntau thaj teb cov ntaub ntawv tseem ceeb nrog kev tsim lag luam zoo.
