Iphepha elishisayo yiphepha elisetshenziswa kakhulu elimbozwe ngamakhemikhali ashintsha umbala uma kushisa.Lesi sakhiwo esiyingqayizivele siyenza ilungele ukusetshenziswa ezinhlelweni ezihlukene ezihlanganisa amarisidi, amalebula namathikithi.Ukuze uqonde ukwakheka kwamakhemikhali ephepha elishisayo, kubalulekile ukuhlola izithako ezibalulekile ezilivumela ukuthi lenze umsebenzi walo ohlosiwe.
Ingxenye yamakhemikhali eyinhloko yephepha elishisayo amadayi angezwani nokushisa.Lo dayi ngokuvamile uyinhlanganisela engenambala ebhekana nokusabela kwamakhemikhali lapho kushisa, okubangela ukushintsha kombala okubonakalayo.Odayi abasetshenziswa kakhulu ephepheni elishisayo odayi be-leuco, abaziwa ngezici zabo ezishintshayo ezishintsha umbala.Lapho iphepha elishisayo lishiselwa, udayi ongenambala ubhekana nenqubo ebizwa ngokuthi i-thermochromism, okuwubangela ukuba ushintshe usuke esimweni esingenambala ube nemibala.Lokhu kushintsha kombala yikho okudala izithombe ezibonakalayo nombhalo ephepheni elishisayo.
Ngaphezu kodayi, iphepha elishisayo liqukethe namakhemikhali onjiniyela.Unjiniyela ngokuvamile uyinhlanganisela ye-asidi engenambala ehambisana nodayi lapho ishiswa, okubangela ukuthi udayi ushintshe umbala.Unjiniyela udlala indima ebalulekile enqubweni yokuphrinta eshisayo, ekhuthaza ukushintsha kombala wedayi nokuqinisekisa ukuthi izithombe eziphrintiwe nombhalo kucacile futhi kuyafundeka.
Ukwengeza, iphepha elishisayo linengubo evikelayo esiza ukuvikela izithombe eziphrintiwe nombhalo.Lokhu kunamathela kuvame ukwenziwa ngenhlanganisela yamakhemikhali afana namawakisi nama-resin ukuze kunikeze ungqimba oluvikelayo endaweni ephrintiwe.Ukugqoka okuvikelayo akusizi nje kuphela ukuvimbela ukuphrinta kusuka ekuthunjweni nasekufiphaleni, kodwa futhi kuthuthukisa ukuqina okuphelele kwephepha elishisayo.
Kuyaphawuleka ukuthi ukwakheka kwamakhemikhali ephepha elishisayo lingahluka kuye ngokuthi lihloselwe ukusetshenziswa.Isibonelo, iphepha elishisayo elisetshenziselwa amarisidi lingase libe nokwakheka kwamakhemikhali okuhlukile kunephepha elishisayo elisetshenziselwa amalebula noma amathikithi.Abakhiqizi bangakwazi ukulungisa ukwakheka kwamakhemikhali ephepha elishisayo ukuze lihlangabezane nezimfuneko ezithile, ezifana nokumelana nokufiphala, ukumelana namanzi, noma ukuhambisana nobuchwepheshe bokuphrinta obuhlukahlukene.
Nakuba iphepha elishisayo linikeza izinzuzo eziningi, kuhlanganise nokunyathelisa okusheshayo kanye nezindleko zokunakekelwa okuphansi, kufanele liphathwe ngokucophelela ngenxa yokwakheka kwamakhemikhali.Ukuchayeka kumakhemikhali athile noma izinga lokushisa elidlulele kungathinta ukusebenza nempilo yephepha elishisayo.Isitoreji esifanele kanye nezindlela zokuphatha zibalulekile ukuze kuqinisekiswe ukuthi iphepha elishisayo lihlala lisesimweni esifanele ukuze lisetshenziswe.
Kafushane, ukuqonda ukwakheka kwamakhemikhali ephepha elishisayo kubalulekile ekuqondeni izakhiwo zalo eziyingqayizivele nezindlela ezisetshenziswayo.Inhlanganisela yodayi abashisayo, amakhemikhali kanjiniyela, nezimbozo ezivikelayo zenza iphepha elishisayo lilethe imiphumela yekhwalithi ephezulu, yokuphrinta esheshayo.Ngokuqonda okujulile kokwakheka kwamakhemikhali ephepha elishisayo, abasebenzisi bangenza izinqumo ezinolwazi mayelana nokusetshenziswa nokugcinwa kwalo, ekugcineni bakhulise ukusebenza kahle kwalo ezinhlelweni ezihlukahlukene zokuphrinta.
