Acetonendi mankhwala omwe amagwiritsidwa ntchito kwambiri ndi mitundu yosiyanasiyana ya mafakitale ndi nyumba. Kutha kwake kusungunula zinthu zambiri komanso kuyanjana kwake ndi zinthu zosiyanasiyana kumapangitsa kuti pakhale njira yothetsera ntchito zosiyanasiyana, kuyambira kuchotsa 指甲 mafuta mpaka kuyeretsa magalasi. Komabe, mbiri yake yoyaka moto nthawi zambiri imasiya ogwiritsa ntchito ndi akatswiri achitetezo chimodzimodzi ndi mafunso oyaka. Kodi 100% ya acetone imatha kuyaka? Nkhaniyi ikufotokoza za sayansi kumbuyo kwa funsoli ndikuwunika zoopsa ndi zenizeni zomwe zimagwirizanitsidwa ndi kugwiritsa ntchito acetone yoyera.

Kuti timvetsetse kupsa kwa acetone, choyamba tiyenera kuyang'ana kapangidwe kake ka mankhwala. Acetone ndi ketone ya kaboni itatu yomwe imakhala ndi mpweya ndi kaboni, ziwiri mwazinthu zitatu zofunika pakuyaka (chachitatu kukhala haidrojeni). M'malo mwake, mankhwala a acetone, CH3COCH3, amakhala ndi zomangira ziwiri komanso ziwiri pakati pa maatomu a carbon, zomwe zimapereka mwayi wochitapo kanthu mwachangu zomwe zingayambitse kuyaka.

Komabe, chifukwa chakuti chinthu chili ndi zigawo zoyaka moto sizikutanthauza kuti chidzayaka. Mikhalidwe yoyaka moto imaphatikizansopo ndende komanso kukhalapo kwa gwero loyatsira. Pankhani ya acetone, gawo ili limakhulupirira kuti lili pakati pa 2.2% ndi 10% ndi voliyumu mumlengalenga. Pansi pa ndende iyi, acetone sidzayaka.

Izi zikutifikitsa ku gawo lachiwiri la funso: momwe acetone amayaka. Acetone yoyera, ikayatsidwa ndi gwero loyatsira monga moto kapena lawi lamoto, imayaka ngati kukhazikika kwake kuli mkati mwazomwe zimatha kuyaka. Komabe, kutentha kwa acetone kumakhala kocheperako poyerekeza ndi mafuta ena ambiri, zomwe zimapangitsa kuti zisayatse m'malo otentha kwambiri.

Tsopano tiyeni tilingalire tanthauzo lenileni la chidziwitso ichi. M'malo ambiri am'nyumba ndi m'mafakitale, acetone yoyera sapezeka kawirikawiri m'malo okwera kwambiri kuti azitha kuyaka. Komabe, m'njira zina zamafakitale kapena zosungunulira pomwe kuchuluka kwa acetone kumagwiritsidwa ntchito, kusamala kuyenera kuchitidwa kuti zitsimikizire chitetezo. Ogwira ntchito pamankhwalawa ayenera kukhala ophunzitsidwa bwino za momwe angagwiritsire ntchito mosamala, kuphatikiza kugwiritsa ntchito zida zolimbana ndi malawi komanso kupewa kwambiri zoyatsira.

Pomaliza, 100% acetone imatha kuyaka nthawi zina koma pokhapokha ngati ndende yake ili mkati mwamtundu winawake komanso pamaso pa gwero loyatsira. Kumvetsetsa izi ndikugwiritsa ntchito njira zodzitetezera kungathandize kupewa moto kapena kuphulika kulikonse komwe kumabwera chifukwa chogwiritsa ntchito mankhwala otchukawa.
