Eminyakeni yamuva nje, isidingo semikhiqizo enobungani nemvelo kanye nehlala isikhathi eside besilokhu sikhula. Lo mkhuba uholela ekushintsheni okukhulu endleleni izinqubo zokukhiqiza eziqhutshwa ngayo ezimbonini, ikakhulukazi ezindaweni zokunamathela kanye nokunamathela. Ukuthuthukiswa kokunamathela okuhlanganisiwe okungenazincibilikisi sekuyinto ephumelelayo emvelweni, okunikeza enye indlela efanelekile kunezinti ezisekelwe ezincibilikisini zendabuko. Enye yalezi zinto ezintsha ukunamathela okunamathelayo okungenazincibilikisi, okuthola ukunakwa ngenxa yezakhiwo zawo ezinobungani nemvelo kanye nokusebenza okuphezulu.
Izinamathelisi ezisekelwe ku-solventsekuyisikhathi eside iyinto ebalulekile embonini yokukhiqiza ngenxa yokusebenza kwayo kahle ezintweni zokubopha. Kodwa-ke, ukusetshenziswa kwayo kudala izinkinga eziningi zemvelo nezempilo. Amakhemikhali e-organic aguquguqukayo (ama-VOC) akhishwa ngesikhathi sokusetshenziswa nokwelashwa kwezinamathiseli ezisekelwe ku-solvent angabangela ukungcola komoya futhi abeke izingozi empilweni yabasebenzi. Ukuze kuxazululwe lezi zinselele, ukuthuthukiswa kwezinamathiseli ezihlanganisiwe ezingenayo i-solvent kuvula indlela yezindlela ezizinzile nezinobungani nemvelo zezinqubo zokubopha nokulamina.
Izinti zokunamathisela ezingenazincibilikisi ziyisibonelo esivelele senti yokunamathisela engenazincibilikisi eguqule imboni. Lolu hlelo lokunamathisela olusha luqeda isidingo sezincibilikisi, okwenza kube yindlela enobungani nemvelo futhi ephephile. Ngokusebenzisa inhlanganisela yezithako ezisebenzayo, izinti zokunamathisela ezingenazincibilikisi ziyabophana ngokusabela kwamakhemikhali kunokuhwamuka kwesincibilikisi. Lokhu akugcini nje ngokunciphisa ukukhishwa kwama-VOC ayingozi, kodwa futhi kuthuthukisa ukuphepha okuphelele kwenqubo yokuncibilikisa.
Izinzuzo zemvelo zeizinti zokunamathisela ezingenalutho oluyi-solventkwelula ngale kokukhishwa okuncishisiwe kwamakhemikhali e-organic aguquguqukayo. Ukungabi naso isinyibilikisi kusho ukuthi akukho bungozi bokubhajwa kwesinyibilikisi ku-laminate, okuholela kumkhiqizo wokugcina ohlanzekile nohlala isikhathi eside. Ngaphezu kwalokho, ukususa izinyibilikisi kwenza kube lula ukuphinda kusetshenziswe kanye nokulahlwa kwezinto ezilahliwe, okuphinde kube negalelo enqubweni yokukhiqiza eluhlaza.
Ngaphezu kwezinzuzo zazo zemvelo, izinti zokunamathisela ezingelamanzi ezingenayo i-solvent zinikeza izici zokusebenza ezinhle kakhulu. Ngenxa yokuthi azinazo i-solvent, okuqukethwe kwezinto eziqinile kufomula yokunamathisela kuphakeme, okuholela ekubopheni okuqinile nokuhlala isikhathi eside. Le ngcina esebenza kahle iyakwazi ukubopha izinhlobo ezahlukene ze-substrates, okuhlanganisa ifilimu, i-foil kanye nephepha, okwenza kube yisisombululo esiguquguqukayo sezinhlelo ezahlukene zokunamathisela. Ngaphezu kwalokho, izinti zokunamathisela ezingenayo i-solvent zinikeza ukumelana okuhle kakhulu nokushisa namakhemikhali, okuqinisekisa ukuhlala isikhathi eside nokuthembeka kwezinto ezihlanganisiwe.
Ukwamukelwa kwezinamathelisi ezihlanganisiwe ezingenaso isinyibilikisi, njengeizinti zokunamathisela ezingenalutho oluyi-solvent, imelela isinyathelo esibalulekile ekuphishekeleni imikhuba yokukhiqiza esimeme. Njengoba izimboni ziqhubeka nokubeka phambili umthwalo wemfanelo wezemvelo, kulindeleke ukuthi isidingo sezixazululo zokunamathela ezinobungani nemvelo sikhule. Abakhiqizi baphendukela kakhulu ezintanjeni zokunamathela ezingenayo i-solvent ukuze bahlangabezane nezidingo zomthetho, banciphise ukuthinteka kwazo kwezemvelo futhi bakhange abathengi abaqaphela imvelo.
Intuthuko ekunamatheni okuhlanganisiwe okungenazincibilikisi ayigcinanga nje ngokuguqula imboni yokunamathelisa nokubopha, kodwa futhi yabeka indinganiso entsha yokukhiqiza enobungani nemvelo. Ngokwamukela lezi zixazululo zokunamathelisa ezintsha, izinkampani zingalandela imikhuba eqhubekayo ngenkathi zigcina amazinga aphezulu okusebenza kanye nekhwalithi. Ukushintshela ekunamatheni okunamathelisa okungenazincibilikisi kubonisa ushintsho oluhle ekukhiqizeni oluya ekusaseni eliluhlaza nelizinzile.
Ngamafuphi, ukuthuthukiswa nokwamukelwa kwezinti ezihlanganisiwe ezingenayo i-solvent, ikakhulukazi izinti ezihlanganisiwe ezingenayo i-solvent, kubonisa intuthuko enkulu ekuvikelweni kwemvelo embonini yokukhiqiza. Lezi zixazululo ezintsha zokunamathela zinikeza enye indlela eqhubekayo kunezinti ezisekelwe ku-solvent, zixazulula izinkinga zemvelo ngenkathi ziletha amakhono okubopha asebenza kahle kakhulu. Njengoba isidingo semikhiqizo enobungani nemvelo siqhubeka nokukhula, indima yezinti ezihlanganisiwe ezingenayo i-solvent ekukhuthazeni ukuvikelwa kwemvelo kanye nentuthuko eqhubekayo izogqama kakhulu emkhakheni wokukhiqiza.
