Umbuzo othi "Ingabe i-acetone ingancibilikisa ipulasitiki?"kuyinto evamile, evame ukuzwakala ezindlini, kuma-workshops, kanye nemibuthano yesayensi.Impendulo, njengoba kuvela, iyinkimbinkimbi, futhi lesi sihloko sizocubungula izimiso zamakhemikhali kanye nokusabela okuhambisana nalesi simo.

i-acetoneiyinhlanganisela elula ephilayo engowomndeni we-ketone.Inefomula yamakhemikhali ethi C3H6O futhi yaziwa kakhulu ngekhono layo lokuncibilikisa izinhlobo ezithile zepulasitiki.Ipulasitiki, ngakolunye uhlangothi, yigama elibanzi elihlanganisa izinhlobonhlobo zezinto ezenziwe umuntu.Ikhono le-acetone lokuncibilikisa ipulasitiki lincike ohlotsheni lwepulasitiki oluhilelekile.

Lapho i-acetone ihlangana nezinhlobo ezithile zepulasitiki, ukusabela kwamakhemikhali kwenzeka.Ama-molecule epulasitiki akhangwa ama-acetone ngenxa yesimo sawo se-polar.Lokhu kukhanga kuholela ekutheni ipulasitiki ibe uketshezi, okuholela “ekuncibilikeni” komphumela.Kodwa-ke, kubalulekile ukuqaphela ukuthi lokhu akuyona inqubo yangempela yokuncibilika kodwa ukusebenzisana kwamakhemikhali.

Isici esiyinhloko lapha yi-polarity yama-molecule ahilelekile.Ama-molecule asezindaweni ezishisayo, njenge-acetone, anokusabalalisa kweshaja okuhle ngokwengxenye kanye nokubi ngokwengxenye ngaphakathi kwesakhiwo sawo.Lokhu kuzivumela ukuthi zihlanganyele futhi zihlangane nezinto ezimhlophe njengezinhlobo ezithile zepulasitiki.Ngalokhu kusebenzisana, ukwakheka kwamangqamuzana epulasitiki kuyaphazamiseka, okuholela “ekuncibilikeni” kwawo okusobala.

Manje, kubalulekile ukuhlukanisa phakathi kwezinhlobo ezahlukene zepulasitiki lapho usebenzisa i-acetone njenge-solvent.Nakuba amanye amapulasitiki afana ne-polyvinyl chloride (PVC) kanye ne-polyethylene (PE) esengozini enkulu yokukhangwa i-acetone polar, amanye afana ne-polypropylene (PP) ne-polyethylene terephthalate (PET) awasebenzi kangako.Lo mehluko ekusebenzeni kabusha kungenxa yezakhiwo zamakhemikhali ezihlukene kanye ne-polarity yamapulasitiki ahlukene.

ukuchayeka isikhathi eside kwepulasitiki ku-acetone kungaholela ekulimaleni unomphela noma ukucekelwa phansi kwezinto.Lokhu kungenxa yokuthi ukusabela kwamakhemikhali phakathi kwe-acetone nepulasitiki kungase kuguqule ukwakheka kwamangqamuzana okugcina, okuholela ekushintsheni kwezakhiwo zayo ezibonakalayo.

Ikhono le-acetone "lokuncibilikisa" ipulasitiki liwumphumela wokusabela kwamakhemikhali phakathi kwama-molecule e-acetone esendaweni epholile kanye nezinhlobo ezithile zepulasitiki epholile.Lokhu kusabela kuphazamisa ukwakheka kwamangqamuzana epulasitiki, okuholela ekubonakaleni kwawo uketshezi.Kodwa-ke, kubalulekile ukuqaphela ukuthi ukuchayeka isikhathi eside ku-acetone kungaholela ekulimaleni unomphela noma ukucekelwa phansi kwezinto zepulasitiki.
