Iphepha leThermal liphepha elisetyenziswa kakhulu eliqatywe ngemichiza elitshintsha umbala xa lishushu.Le propati iyingqayizivele yenza ukuba ilungele ukusetyenziswa kwiinkqubo ezahlukeneyo ezibandakanya iirisithi, iilebhile kunye namatikiti.Ukuqonda ukubunjwa kweekhemikhali zephepha le-thermal, kubalulekile ukuhlolisisa izithako eziphambili ezivumela ukuba zenze umsebenzi ojoliswe kuwo.
Icandelo eliphambili leekhemikhali zephepha le-thermal lidayi elinobushushu.Le dayi idla ngokuba yinkomponi engenambala eyenza imichiza xa ishushu, nto leyo ebangela utshintsho olubonakalayo lombala.Ezona dayi zisetyenziswa ngokuqhelekileyo kwiphepha le-thermal yidayi ye-leuco, eyaziwa ngokuba neempawu eziguqukayo zokutshintsha umbala.Xa iphepha lethermal lifudunyezwa, idayi engenambala ifumana inkqubo ebizwa ngokuba yithermochromism, ibangela ukuba itshintshe ingabinambala ibe nemibala.Olu tshintsho lombala yinto eyenza imifanekiso ebonakalayo kunye nesicatshulwa kwiphepha le-thermal.
Ukongeza kwidayi, iphepha le-thermal likwaqulethe iikhemikhali zomphuhlisi.Umphuhlisi udla ngokuba yi-acidic compound engenambala edibana nedayi xa ishushu, ibangela ukuba idayi itshintshe umbala.Umthuthukisi udlala indima ebalulekileyo kwinkqubo yokushicilela i-thermal, ekhuthaza ukuguqulwa kombala wedayi kunye nokuqinisekisa ukuba imifanekiso eprintiweyo kunye nesicatshulwa sicacile kwaye sifundeka.
Ukongezelela, iphepha le-thermal linengubo yokukhusela enceda ukukhusela imifanekiso eprintiweyo kunye nesicatshulwa.Olu tyaba ludla ngokwenziwa ngokudityaniswa kweekhemikhali ezifana ne-wax kunye ne-resins ukunika umaleko okhuselayo kwindawo eprintiweyo.Ukugquma okukhuselekileyo akuncedi nje kuphela ukukhusela iiprints ekutshitshiseni kunye nokucima, kodwa kwandisa ukuqina okupheleleyo kwephepha le-thermal.
Kuyafaneleka ukuba uqaphele ukuba ukubunjwa kweekhemikhali zephepha le-thermal kunokwahluka ngokuxhomekeke kusetyenziso lwayo.Umzekelo, iphepha le-thermal elisetyenziselwa iirisithi linokuba nokwakheka kweekhemikhali ezahlukeneyo kunephepha le-thermal elisetyenziselwa iilebhile okanye amatikiti.Abavelisi banokulungelelanisa ukubunjwa kweekhemikhali zephepha le-thermal ukuhlangabezana neemfuno ezithile, ezifana nokumelana nokucima, ukuxhathisa kwamanzi, okanye ukuhambelana nobugcisa obuhlukeneyo bokushicilela.
Ngelixa iphepha le-thermal libonelela ngeenzuzo ezininzi, kubandakanywa ukuprintwa ngokukhawuleza kunye neendleko zokugcinwa okuphantsi, kufuneka ziphathwe ngononophelo ngenxa yokwakheka kweekhemikhali.Ukuvezwa kweekhemikhali ezithile okanye amaqondo obushushu agqithisileyo kunokuchaphazela ukusebenza kunye nobomi bephepha le-thermal.Ukugcinwa ngokufanelekileyo kunye neendlela zokuphatha kubalulekile ukuqinisekisa ukuba iphepha le-thermal lihlala likwimeko efanelekileyo yokusetyenziswa.
Isishwankathelo, ukuqonda ukubunjwa kweekhemikhali zephepha le-thermal kubalulekile ekuqondeni iimpawu zayo ezizodwa kunye nokusetyenziswa.Ukudityaniswa kwedayi ezishushu, iikhemikhali zomphuhlisi, kunye neengubo ezikhuselayo zenza ukuba iphepha le-thermal linike umgangatho ophezulu, iziphumo zokuprinta ngoko nangoko.Ngokuqonda ngokunzulu ukubunjwa kweekhemikhali zephepha le-thermal, abasebenzisi banokwenza izigqibo ezinolwazi malunga nokusetyenziswa kwayo kunye nokugcinwa kwayo, ekugqibeleni ukwandisa ukusebenza kwayo kwiinkqubo ezahlukeneyo zokuprinta.
