Madhayi anonyungudutsa chinhu chakakosha mumaindasitiri akasiyana-siyana kubva pamapurasitiki nependi kusvika kumavara ehuni neingi dzekudhinda. Madhayi aya anoshanduka-shanduka ane hunhu hwakasiyana-siyana uye mashandisirwo akasiyana-siyana, zvichiita kuti ave akakosha mukugadzira.
Madhayi anonyungudutsa anogona kuiswa mumhando dzakasiyana-siyana, kusanganisira madhayi esimbi akaomarara, madhayi anonyungudutsa mafuta, madhayi enitrocellulose, madhayi epolyester, nezvimwewo. Rudzi rumwe nerumwe rune hunhu hwarwo uye mashandisirwo arwo. Imwe yenzira huru dzekushandisa madhayi anonyungudutsa ndeyemapurasitiki nemaindasitiri ependi. Madhayi aya anogona kunyungudutswa muzvinyungudutsa kuti agadzire mhinduro dzine mavara. Hunhu uhwu hunoita kuti zvive zvakanaka pakupenda zvinhu zvepurasitiki nemapendi. Ingave mavara anopenya ematoyi epurasitiki kana kupenya kwenzvimbo dzakapendwa, madhayi anonyungudutsa anoita basa rakakosha mukuwedzera kutaridzika kwezvigadzirwa izvi.
Mashandisirwo emadhayi e solvent haasi epurasitiki nependi chete; anoshandiswawo zvakanyanya kupenda matanda. Vavezi vematanda vanowanzo shandisa madhayi e solvent kuwedzera ruvara pazvinhu zvakasiyana-siyana zvematanda, zvakaita sefenicha nezvishongo. Madhayi e solvent anopinda mukati mehuni, zvichiita kuti ruvara ruve rwakaenzana uye runogara kwenguva refu. Pamusoro pezvo, hunhu hwayo hwekuoma nekukurumidza hunoita kuti ive yakanaka pakupukuta matanda zvakanaka.
Imwe nzira yakakosha yekushandisa madhayi e solvent ndeyekudhinda inki. Madhayi aya anowanzo shandiswa kugadzira inki yakajeka uye yepamusoro-soro yekudhinda. Kunyungudika kwemadhayi e solvent kunoita kuti zvive nyore kusanganisa ne solvents dzinoenderana, zvichikonzera inki dzekudhinda dzakapararira zvakanaka uye dzinooma nekukurumidza. Izvi zvinoita kuti kudhinda kuve nyore uye kwakanyatsojeka mumaindasitiri akasiyana-siyana akadai sekurongedza, kuburitsa mabhuku uye machira.
Ngationgororei zvinhu zvinoita kuti madhayi e solvent aonekwe. Chinhu chinonyanya kukosha ndechekuti chiedza chayo hachichinji, chinoita kuti mavara arambe akajeka uye asingatsvedzi kunyangwe akavhenekerwa nezuva kana mamwe marudzi emwaranzi yeUV. Izvi zvakakosha pakushandisa zvinoda kuchengetedza ruvara kwenguva refu, zvakaita sepurasitiki yekunze kana nzvimbo dzakapendwa.
Madhayi e solvent haapindi makemikari zvakanyanya, zvichiita kuti akwanise kushandiswa mumaindasitiri anowanzosangana nemakemikari akaomarara, akadai sema coatings emotokari kana emaindasitiri. Anochengetedza ruvara rwakanaka kunyangwe kana akasangana ne solvents, mafuta kana acids, zvichiita kuti agare kwenguva refu uye agare kwenguva refu.
Pamusoro pezvo, madhayi e solvent anoratidza kugadzikana kwakanyanya pakupisa, zvichiita kuti akwanise kushandiswa pakupisa kwakanyanya. Chinhu ichi chinobatsira zvikuru mukugadzira mapurasitiki kana pakupenda zvinhu zvinogona kupiswa.
Mukupedzisa, madhayi e solvent imhando dzakasiyana-siyana dzemavara dzinoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana. Kushandiswa kwawo mumaindasitiri epurasitiki nekupenda kunogona kukonzera zvigadzirwa zvinopenya uye zvinoyevedza. Vavezi vematanda vanobatsirwa nekukwanisa kwavo kupinda mushinda dzematanda, zvichikonzera mavara anogara kwenguva refu. Indasitiri yeinki yekudhinda inovimba nehunhu hwemadhayi e solvent anooma nekukurumidza uye akapararira zvakanaka kuti agadzire inki dzekudhinda dzemhando yepamusoro. Hunhu hwemadhayi e solvent, kusanganisira kukurumidza kwechiedza, kuramba makemikari, uye kugadzikana kwekupisa, zvinobatsira mukushandiswa kwawo kwakakura uye kugara kwenguva refu. Ingave kuwedzera ruvara kumatoyi epurasitiki, kudhaya matanda, kana magadzirirwo akaomarara ekudhinda, madhayi e solvent anoita basa rakakosha mukusimudzira runako nekushanda kwezvigadzirwa zvakawanda.
