I-acetoneyikhompawundi yeekhemikhali esetyenziswa ngokubanzi eneentlobo ngeentlobo zezicelo zamashishini nezasekhaya. Ukukwazi ukunyibilikisa izinto ezininzi kunye nokuhambelana kwayo kunye nezixhobo ezahlukeneyo kwenza kube yisisombululo soluhlu lwemisebenzi, ukusuka ekususeni ioli ye-指甲 ukucoca i-glassware. Nangona kunjalo, iprofayili yayo yokutsha isoloko ishiya abasebenzisi kunye neengcali zokhuseleko ngokufanayo kunye nemibuzo evuthayo. Ngaba i-100% ye-acetone inokutsha? Eli nqaku lihlolisisa isayensi emva kwalo mbuzo kwaye liphonononga ingozi kunye neenyani ezinxulumene nokusetyenziswa kwe-acetone ecocekileyo.

Ukuqonda ukutsha kwe-acetone, kufuneka siqale sihlolisise ubume bayo beekhemikhali. I-acetone yi-3-carbon ketone equlethe zombini i-oksijini kunye nekhabhoni, ezimbini kwizinto ezintathu eziyimfuneko zokutsha (eyesithathu i-hydrogen). Enyanisweni, ifomula yeekhemikhali ze-acetone, i-CH3COCH3, iqulethe zombini iibhondi enye kunye nembini phakathi kwe-athomu ye-carbon, inika ithuba lokuphendula ngokukhululeka okungakhokelela ekutshisweni.

Nangona kunjalo, ngenxa yokuba into iqulethe izinto ezinokutsha ayithethi ukuba iya kutsha. Iimeko zokutsha zikwabandakanya umda wokuxininisa kunye nobukho bomthombo wokutshisa. Kwimeko ye-acetone, lo mqobo ukholelwa ukuba uphakathi kwe-2.2% kunye ne-10% ngomthamo emoyeni. Ngezantsi kolu gxininiso, i-acetone ayiyi kuvutha.

Oku kusizisa kwinxalenye yesibini yombuzo: iimeko apho i-acetone ivutha khona. I-acetone ecocekileyo, xa ibonakaliswe kumthombo wokutshisa njengentlantsi okanye ilangatye, iya kutshisa ukuba ukugxila kwayo kungaphakathi koluhlu lokutsha. Nangona kunjalo, iqondo lokushisa elivuthayo le-acetone liphantsi kakhulu xa lithelekiswa namanye amaninzi amaninzi, okwenza kube lula ukuvutha kwiindawo ezinobushushu obuphezulu.

Ngoku makhe siqwalasele iimpembelelo zelizwe lokwenyani zolu lwazi. Kwiimeko ezininzi zasekhaya kunye nezamashishini, i-acetone ecocekileyo ayifane idibane noxinzelelo oluphezulu ngokwaneleyo ukuba lunokutsha. Nangona kunjalo, kwiinkqubo ezithile zoshishino okanye ukusetyenziswa kwe-solvent apho kusetyenziswe i-acetone ephezulu, amanyathelo ongezelelweyo kufuneka athathwe ukuqinisekisa ukhuseleko. Abasebenzi abaphatha le michiza kufuneka baqeqeshwe kakuhle kwiindlela zokuphatha ngokukhuselekileyo, kubandakanywa nokusetyenziswa kwezixhobo zokulwa nomlilo kunye nokuphepha okungqongqo kwemithombo yokutshisa.

Ukuqukumbela, i-100% ye-acetone inokutsha phantsi kweemeko ezithile kodwa kuphela xa ukugxininiswa kwayo kuphakathi koluhlu oluthile kunye nobukho bomthombo wokutshisa. Ukuqonda ezi meko kunye nokuphumeza amanyathelo okhuseleko afanelekileyo kunokunceda ukuthintela nayiphi na imililo enokubakho okanye uqhushumbo olubangelwa kukusetyenziswa kwale khompawundi yekhemikhali idumileyo.
