Mubvunzo "Acetone inogona kunyungudutsa plastiki?"ndiyo yakajairika, inowanzonzwika mudzimba, maworkshop, uye nesainzi madenderedzwa.Mhinduro, sezvainozoitika, inonetsa, uye chinyorwa ichi chichanyura mune makemikari misimboti uye maitiro ari pasi peichi chiitiko.

acetoneiri nyore organic compound iyo ndeyemhuri ketone.Iyo ine kemikari formula C3H6O uye inozivikanwa nekugona kwayo kunyungudutsa mamwe marudzi epurasitiki.Plastiki, kune rumwe rutivi, izwi rakafara rinofukidza huwandu hwakawanda hwezvinhu zvakagadzirwa nevanhu.Kugona kweacetone kunyungudutsa plastiki kunoenderana nerudzi rwepurasitiki inobatanidzwa.

Kana acetone ikasangana nemamwe marudzi epurasitiki, kemikari inoitika.Mamorekuru epurasitiki anokwezvwa kune acetone mamorekuru nekuda kwehunhu hwawo hwepolar.Kukwezvwa uku kunoita kuti plastiki inyungudike, zvichikonzera “kunyungudika” kuita.Nekudaro, zvakakosha kuti uzive kuti iyi haisi nzira yekunyungudika chaiyo asi kupindirana kwemakemikari.

Chinhu chakakosha pano ndiyo polarity yemamorekuru anobatanidzwa.Polar mamorekuru, akadai seacetone, ane chikamu chakanaka uye chakashata chechaji yekugovera mukati mechimiro chavo.Izvi zvinovabvumira kudyidzana uye kubatana nezvinhu zvepolar semamwe marudzi epurasitiki.Kuburikidza nekudyidzana uku, chimiro chepurasitiki chemolecular chinokanganiswa, zvichiita kuti iite se "kunyungudika".

Zvino, zvakakosha kusiyanisa pakati pemhando dzakasiyana dzepurasitiki kana uchishandisa acetone sechinhu chinonyungudutsa.Nepo mamwe mapurasitiki akaita sepolyvinyl chloride (PVC) uye polyethylene (PE) ari nyore kubatwa neacetone's polar attraction, mamwe senge polypropylene (PP) uye polyethylene terephthalate (PET) haanyanye kuita.Uyu mutsauko mukuita zvekare unokonzerwa nekusiyana kwemakemikari zvimiro uye polarities yemapurasitiki akasiyana.

kuratidzwa kwenguva refu kwepurasitiki kune acetone kunogona kukonzera kukuvara zvachose kana kushatiswa kwezvinhu.Izvi zvinodaro nekuti kemikari inopindirana pakati peacetone nepurasitiki inogona kushandura chimiro chemolecular chekupedzisira, zvichikonzera shanduko mune zvayo zvemuviri.

Kugona kweacetone "kunyungudusa" epurasitiki imhaka yemakemikari anoita pakati pepolar acetone mamorekuru uye mamwe marudzi epolar plastiki.Kuita uku kunovhiringa chimiro chepurasitiki chemolecular, zvichiita kuti riite serinonyunguduka.Nekudaro, zvakakosha kuti uzive kuti kuratidzwa kwenguva refu kune acetone kunogona kukonzera kukuvara zvachose kana kushatiswa kwezvinhu zvepurasitiki.
