Ezweni lokunamathela, ukukhetha izinti ezinamathelayo ezingenazo izinyibilikisi nezisekelwe ku-solvent kungaba nomthelela omkhulu ekusebenzeni, ukuphepha kanye nomphumela wemvelo womkhiqizo wokugcina. Uma kukhulunywa ngezinti ezinamathelayo, ukuqonda umehluko phakathi kwezinketho ezingenazo izinyibilikisi nezisekelwe ku-solvent kubalulekile ekwenzeni isinqumo esinolwazi. Ake sihlole umehluko obalulekile kanye nezinzuzo zezinti ezinamathelayo ezingenazo izinyibilikisi uma kuqhathaniswa nezinye izindlela ezisekelwe ku-solvent.
Izinti ezisekelwe ku-solvent, njengoba igama lisho, ziqukethe ama-volatile organic compounds (ama-VOC) asebenza njengabathwali bezithako zokunamathela. Lawa ma-volatile organic compounds akhishwa emoyeni ngesikhathi sokwakhiwa nokuqiniswa, okubeka izingozi ezingaba khona empilweni nasemvelweni. Ngokuphambene nalokho, izinti ezinamathelayo ezingena-solvent zakhiwe ngaphandle kwama-volatile organic compounds, okwenza kube inketho ephephile nenobungani nemvelo. Lokhu kubaluleke kakhulu ezimbonini ezinemithetho eqinile yokukhishwa kwegesi kanye nokuphepha kwabasebenzi.
Omunye wemehluko omkhulu phakathi kwe-solvent-free kanye ne-izinti zokunamathisela ezisekelwe ku-solventinqubo yabo yokusebenzisa kanye nokulungisa. Izinti ezisekelwe ku-solvent zidinga ukuhwamuka kwe-solvent ukuze kufezwe ukubophana, okungaholela ezikhathini ezinde zokulungisa futhi kungabangela izinkinga zekhwalithi yomoya. Izinti ezingezona izinti ezincibilikisayo, ngakolunye uhlangothi, ziyaphilisa ngezindlela ezifana nomswakama, ukushisa, noma ingcindezi, okuhlinzeka ngokucubungula okusheshayo kanye nesikhathi esincishisiwe sokungasebenzi. Lokhu kungandisa ukusebenza kahle kokukhiqiza futhi konge izindleko kubakhiqizi.
Ngaphezu kwalokho, ukungabikho kwezinyibilikisi ezinamathelayo ze-laminating ezingenayo i-solvent kusiza ekuthuthukiseni ukusebenza kwe-bonding kanye nokuqina. Ngokuhamba kwesikhathi, izinamathelayo ezisekelwe ku-solvent zingancipha futhi zibe buthaka njengoba i-solvent iphela, okungenzeka ukuthi zibeke engcupheni ubuqotho be-laminate. I-glue engenayo i-solvent isebenzisa ifomula engaguquki ukuze inikeze isibopho esizinzile nesihlala isikhathi eside, okuqinisekisa ikhwalithi kanye nobude bemikhiqizo ye-laminate.
Ngokombono wezemvelo, ukushintshela ezintini zokunamathela ezingelapheki kuhambisana nokugcizelela okukhula ekusimeni okuzinzile kanye nemikhuba yokukhiqiza eqaphela imvelo. Izintini zokunamathela ezingenapheki kusiza ukunciphisa umthelela wemvelo wenqubo yokunamathela ngokususa ukukhishwa kwe-VOC kanye nokunciphisa imfucuza eyingozi. Lokhu kubaluleke kakhulu ezimbonini ezifana nokupakisha, lapho izixazululo eziqhubekayo zifunwa khona ukuze kuhlangatshezwane nezidingo zabathengi kanye nezomthetho.
Ngokuphathelene nokuphepha, ukusetshenziswa kwezinamathelisi ezinamathelayo ezingenayo i-solvent kunikeza indawo yokusebenza enempilo kubasebenzi kanye nabasebenzi. Njengoba ukuchayeka entuthwini eyingozi kanye namakhemikhali kuncipha, nengozi yezifo zokuphefumula kanye nokucasuka kwesikhumba iyancipha, okukhuthaza impilo yendawo yokusebenza iyonke. Lokhu kungathuthukisa isimilo, kunciphise ukungabikho emsebenzini futhi kudale isithombe esihle senkampani.
Ngamafuphi, ukushintsha kusuka ekunamatheni okunamathelayo okusekelwe ku-solvent kuya ekunamatheni okungena-solvent kumelela intuthuko ebalulekile kubuchwepheshe bokunamathela, okunikeza izinzuzo eziningi ezindaweni ezahlukene. Izakhiwo zemvelo eziphakeme, ukusebenza okuthuthukisiwe, izikhathi zokuphulukiswa okusheshayo kanye nokuphepha okuthuthukisiwe kwenza ukunamathiswa okungena-solvent kube ukukhetha okuhle kakhulu kwabakhiqizi abafuna ukuthuthukisa izinqubo zabo zokunamathiswa. Njengoba imboni iqhubeka nokubeka phambili ukusimama nokusebenza kahle, ukwamukelwa kokunamathiswa okulinganisa okungena-solvent kulungele ukuba yindinganiso entsha, okuletha ushintsho oluhle emabhizinisini kanye naseplanethi.
