Chemical solvents ndi zinthu zomwe zimasungunula solute, zomwe zimapangitsa yankho. Amagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana, kuphatikiza mankhwala, utoto, zokutira, ndi zoyeretsera. Kusinthasintha kwa zosungunulira zamankhwala kumawapangitsa kukhala ofunikira m'mafakitale ndi ma labotale.
Imodzi mwa ntchito zoyamba za zosungunulira za mankhwala ndikuthandizira kusintha kwa ma chemical. Mwachitsanzo, m'makampani opanga mankhwala, zosungunulira zimagwiritsidwa ntchito pochotsa zinthu zomwe zimagwira ntchito muzopangira, kuwonetsetsa kuti mankhwala ndi othandiza komanso otetezeka kuti amwe. Zosungunulira zodziwika bwino m'gawoli zimaphatikizapo ethanol, methanol, ndi acetone, aliyense wosankhidwa chifukwa cha kuthekera kwawo kusungunula zinthu zinazake.
M'makampani opanga utoto ndi zokutira, zosungunulira zamankhwala ndizofunikira kuti mukwaniritse zomwe mukufuna komanso kugwiritsa ntchito. Amathandizira kupenta utoto, kupangitsa kuti ikhale yosavuta komanso nthawi yowuma mwachangu. Zosungunulira monga toluene ndi xylene zimagwiritsidwa ntchito mobwerezabwereza, koma ma volatile organic compounds (VOCs) amatha kubweretsa zoopsa zachilengedwe komanso thanzi. Zotsatira zake, pali chizoloŵezi chokulirapo cha chitukuko cha otsika VOC ndi zosungunulira madzi.
Komanso, zosungunulira za mankhwala n'zofunika kwambiri poyeretsa, kumene zimathandiza kusungunula mafuta, mafuta, ndi zinthu zina zowononga. Zosungunulira monga isopropyl mowa ndi ethyl acetate zimapezeka kawirikawiri m'nyumba zotsukira m'nyumba ndi m'mafakitale, zomwe zimapangitsa kuti zikhale zogwira mtima posunga ukhondo ndi ukhondo.
Komabe, kugwiritsa ntchito mankhwala osungunulira mankhwala sikumakhala ndi mavuto. Zosungunulira zachikhalidwe zambiri zimakhala zowopsa, zomwe zimapangitsa kuti azitsatira malamulo okhwima okhudza momwe angagwiritsire ntchito ndi kutaya. Izi zapangitsa ofufuza ndi opanga kufunafuna njira zina zotetezeka, monga zosungunulira zochokera ku bio zochokera kuzinthu zongowonjezedwanso.
Pomaliza, zosungunulira zamankhwala ndizofunikira m'mafakitale osiyanasiyana, zomwe zimathandizira njira zomwe zimachokera ku kupanga mankhwala mpaka kuyeretsa pamwamba. Pamene kufunikira kwa njira zotetezeka komanso zokhazikika kukukulirakulira, tsogolo la zosungunulira zamankhwala liwona zatsopano zomwe zikufuna kuchepetsa kuwononga chilengedwe ndikusunga mphamvu.
