Kwiminyaka elawulwa ngabantu abasebenza ngetekhnoloji yedijithali, uzinzo lwephepha elitshisayo kunokubonakala ngathi yinto engenakuthelekiswa nanto. Nangona kunjalo, ifuthe lendalo esingqongileyo lemveliso yephepha le-Thermal kunye nokusetyenziswa ngumbandela oxhalabisayo, ngakumbi njengoko amashishini kunye nabathengi baqhubeka nokuxhomekeka kolu hlobo lwephepha leerisithi, iileyibhile kunye nezinye iinkqubo.
Iphepha le-thermal lisetyenziswe ngokubanzi kumashishini ahlukeneyo ngenxa yokulula kunye nokusebenza kweendleko. Ihlala isetyenziswa kwiindawo ezithengisa iindawo zokuprinta zokuprinta iirisithi, kwiCawerCare yeZempilo kwileyibhile, kunye nezinto zokuprinta iileyibhile zokuhambisa. Nangona iPhepha leTherithi lisetyenziswe ngokubanzi, ukuzinza kwazo kungena phantsi kokuhlolwa ngenxa yeekhemikhali ezisetyenziswa kwimveliso yayo kunye nemiceli mngeni enxulumene nokurisayikilisha.
Enye yezona zinto zixhalabisayo malunga nokuzinza kwephepha le-thermal kukusetyenziswa kwe-bisphenol a (bPA) kunye ne-bisphenol s (BPS) ekuthweni kwayo. Ezi khemikhali zaziwa ngabantu abangathabathanga uqobo kwaye zidityaniswe neziphumo zempilo ezibi. Ngelixa abanye abavelisi betshintshile ekuveliseni iphepha le-BPAR elebhu, i-BPS, ihlala isetyenziswa njenge-BPA endaweni ye-BPA, ikwaphakamise inkxalabo malunga nefuthe elinokubakho kwimpilo yabantu nakwisingqongileyo.
Ukongeza, ukuphinda usebenzise kwakhona iphepha le-thermal libonisa imiceli mingeni ebalulekileyo ngenxa yobukho beentambo zekhemikhali. Inkqubo yokuphinda isebenze kwakhona yephepha lemveli ayifanelekanga kwiphepha le-thermal kuba ukudibanisa i-thermal ukungcolisa i-pulp ehlaziyiweyo. Ke ngoko, iphepha le-irmal lihlala lithunyelwa kwi-LandFill okanye izityalo zokutshintshwa, kubangela ukungcoliseka kwendalo kunye nokupheliswa kwezixhobo.
Ngenxa yemiceli mngeni, iinzame ziyaqhubeka ukujongana nemicimbi yokuzinzileyo yephepha le-thermal. Abanye abavelisi baphonononge amanye amatyala eenkomo ezingabinazo iikhemikhali eziyingozi, ngaloo ndlela kuncitshiswa ifuthe lendalo esingqongileyo lemveliso yamaphepha. Ukongeza, sisenza inkqubela phambili kwitekhnoloji yokuphinda isebenze ukuqulunqa iindlela zokwahlula iingubo zenziwe ngempumelelo ephepheni, ngaloo ndlela zinika amandla okuphinda-phinda kwephepha lokusingqongileyo.
Ukusuka kwimbono yabathengi, kukho amanyathelo anokuthathwa ukukhuthaza uzinzo kwiphepha le-thermal. Apho kunokwenzeka, ukukhetha iirisithi ze-elektroniki kwiirisithi eziprintiweyo kunokunceda ukunciphisa imfuno yephepha lomtshato. Ukongeza, ukuvumela ukusetyenziswa kwephepha le-BPA-kunye ne-BPS elinokukhuthaza abavelisi ukuba babeka phambili kuphuhliso lweendlela ezikhuselekileyo.
Kwiminyaka yedijithali, apho unxibelelwano lwe-elektroniki kunye namaxwebhu luyeyona nto iqhelekileyo, uzinzo lwephepha le-thermal lubonakala ngathi luphela. Nangona kunjalo, ukuqhubeka kwayo kusetyenziswa kwizicelo ezahlukeneyo kufuna uvavanyo lwempembelelo yendalo. Ngokulungisa imiba enxulumene nemveliso yemichiza kunye nokurisayikilisha imiceli mngeni, iphepha elitshisayo linokwenziwa izinzile, ngokungqinelana neenjongo ezibanzi zoKhuseleko lweNdalo yokhuseleko lwendalo esingqongileyo kunye nokusebenza kakuhle kwezixhobo.
Isishwankathelo, uzinzo lwephepha elitshisayo kwi-Digital Iminyaka yobudala yedijithali ngumbambano onzima ofuna ukusebenzisana phakathi kwabathathi-nxaxheba kwishishini, abaqulunqi bomgaqo-nkqubo kunye nabathengi. Unyawo lwendawo yokusingqongileyo lwephepha elinomngcipheko lunokuncitshiswa ngokukhuthaza ukusetyenziswa kwengubo ekhuselekileyo kwaye utyale imali ngokutsha. Njengoko sisebenza kwikamva elizinzileyo, kubalulekile ukuba siqwalasele ifuthe lezinto ezibonakala ngathi ziyiphepha lomtshato kunye nomsebenzi wokunciphisa ifuthe labo kwindalo esingqongileyo kwindalo esingqongileyo.
