Iphepha le-thermal yinto esetyenziswayo kwimizi-mveliso eyahlukeneyo kubandakanya ukuthengisa, ibhanki kunye nezinto. Idibene nedayi ekhethekileyo etshintsha umbala xa ifudumele, iyenza ilungele iirisithi zokuprinta, iilebheli kunye nezincamathelisi. Nangona kunjalo, iphepha le-thermal alinakuphinda lisebenze ngeendlela zephepha lemveli ngenxa yobukho beekhemikhali kunye nokungcola. Ke ngoko, iinkqubo ezizodwa ziyafuneka ukuba zisingatha ngokufanelekileyo kwaye zisebenzise iphepha eliyiphepha lebhulukhwe kwaye zinciphise ifuthe lendalo kwindalo esingqongileyo. Kweli nqaku, siza kukhangela amanyathelo abandakanyekileyo ekusebenzeni nasekuqhubekeni kwakhona kwiphepha le-thermal.
Inyathelo lokuqala kwinkqubo yokuphinda isebenze iqokelele ukuqokelela iPhepha leTrans. Oku kungenziwa ngeendlela ezahlukeneyo, ezinjengokubeka imigqomo yokuqokelelwa kwiivenkile ezithengisa iivenkile kunye neeofisi, okanye ukusebenza neenkampani zokurisayikilisha ukuqokelela inkunkuma yephepha eliphantsi. Ukwahlula-hlulwa okufanelekileyo kubalulekile ukuqinisekisa ukuba kuphela iphepha le-thermal liqokelelwe kwaye alixubeki nezinye iintlobo zephepha.
Nje ukuba iqokelelwe, iphepha le-irmal lithuthwa kwindawo yokuphinda isebenze apho ihamba khona ngothotho lwamanyathelo okususa i-DYS kunye nezinye izinto ezingcolileyo. Inyathelo lokuqala kwiSigaba seNkqubo ibizwa ngokuba yi-Pung, apho iphepha le-thermal lixutywe namanzi ukuyiqhekeza ibe yintsini nganye. Le nkqubo inceda ukwahlula idayi kwiintsinga zephepha.
Emva kokutsalwa, umxube uhlolwe ukuze ususe amasuntswana aphezulu kunye nongcoliseko. Ulwelo oluphawuliweyo lubekwe phantsi kwenkqubo yefloti, apho iibhubhu zomoya ziziswa ukuze zahlule idayi emanzini. Idayi ilula kwaye inyibilikisa, inyibilika, ngelixa amanzi acocekileyo elahliwe.
Inyathelo elilandelayo kwinkqubo yokuphinda isebenze kufuneka lisuse iichemicals ezikhoyo kwiPhepha leNqaku. Ezi khemikhali zibandakanya i-bisphenol a (bPA), eyenza njengomphuhlisi we-DYE kwiphepha. I-BPA ingumphazamiso owaziwayo e-Endocrine ebeka umngcipheko kwimpilo yabantu kunye nokusingqongileyo. Iintlobo ezahlukeneyo zetekhnoloji, ezinje nge-carbon ye-carbon kunye ne-ion yotshintshiselwano, zinokusetyenziselwa ukususa i-BPA kunye nezinye iikhemikhali ezivela emanzini.
Nje ukuba idayi kunye neekhemikhali zisuswe ngempumelelo emanzini, amanzi acocekileyo anokusetyenziswa okanye akhutshwe emva konyango olufanelekileyo. Iintsinga zePhepha eseleyo ngoku zinokuchithwa njengokuthi zephepha lemveli lezesithili lisebenze kwakhona. Ipulp ihlanjululwe, iconjululwe kwaye ikhokelwe ukuphucula umgangatho wayo ngaphambi kokuba isetyenziselwe ukwenza iimveliso zamaphepha ezintsha.
Kufuneka kuqatshelwe ukuba ukuphinda kusetyenziswe kwakhona iphepha le-thermal yinkqubo entsonkothileyo efuna itekhnoloji kunye nezixhobo. Ke ngoko, kubalulekile ukuba amashishini nabantu abasebenzisa iphepha elitshisayo ukusebenzisana nendawo ekwamkelweyo yokuqinisekiswa kwakhona ukuqinisekisa ukuphatha ngokufanelekileyo kunye nokurisayikilisha kwakhona.
Ukuqukumbela, iphepha le-thermal, nangona isetyenziswe ngokubanzi, inikezela ngemiceli mngeni esebenzayo ngenxa yobukho beekhemikhali kunye nokungcola. Ukulungiswa kunye nokurisayikilisha iphepha le-thermal kubandakanya amanyathelo amaninzi, kubandakanya ukutywina, ukufuduswa, ukususwa kweekhemikhali kunye nonyango lwefayili. Ngokuphunyezwa kweendlela zokuqokelela ezifanelekileyo nokusebenza nabasebenzi kwakhona, sinokunciphisa ngokufanelekileyo ifuthe lokusingqongileyo kwiPhepha leNqakuna kunye nokukhuthaza iindlela zokulawulwa kwenkunkuma.
