Iphepha elishisayo yiphepha elisetshenziswa kakhulu elimbozwe ngamakhemikhali ashintsha umbala uma kushisa.Ivamise ukusetshenziselwa amarisidi, amathikithi, amalebula, nezinye izinhlelo zokusebenza ezidinga ukuphrinta ngokushesha ngaphandle kwesidingo sikayinki noma i-toner.Nakuba iphepha elishisayo linikeza ukunethezeka nokusebenza kahle, umthelela walo kwezemvelo uphakamise ukukhathazeka ngenxa yamakhemikhali asetshenziswa ekukhiqizeni kwawo kanye nezinselele ezihambisana nokulahlwa kwawo.
Okunye okukhathaza kakhulu imvelo okuhlotshaniswa nephepha elishisayo ukusetshenziswa kwe-bisphenol A (BPA) ekuhlanganiseni.I-BPA iyikhemikhali exhunywe ezinkingeni zezempilo ezahlukahlukene, futhi ukuba khona kwayo ephepheni elishisayo kuphakamisa ukukhathazeka mayelana nokuchayeka okungaba khona kubantu kanye nemvelo.Uma iphepha elishisayo lisetshenziswa kumarisidi nakweminye imikhiqizo, i-BPA ingadlulisela esikhunjeni ngesikhathi sokuphatha futhi ingcolise imifudlana yokugaya kabusha uma ingaphathwa kahle.
Ngaphandle kwe-BPA, ukukhiqizwa kwephepha elishisayo kuhilela ukusetshenziswa kwamanye amakhemikhali nezinto ezingaba nomthelela omubi emvelweni.Inqubo yokukhiqiza ingaholela ekukhishweni kwezinto eziyingozi emoyeni nasemanzini, okubangela ukungcola kanye nokulimala okungaba khona kuzinhlelo zemvelo.Ukwengeza, kunezinselele ekuphatheni iphepha elishisayo ngenxa yokuba khona kwamakhemikhali ekuhlanganiseni, okwenza kube nzima ukubuyisela kabusha noma ukufaka umquba.
Uma iphepha elishisayo lingalahlwanga ngendlela efanele, lingagcina selisendaweni yokulahla imfucumfucu, lapho amakhemikhali asendaweni enamathelayo angangena enhlabathini nasemanzini, abeke ubungozi emvelweni futhi aphazamise izilwane zasendle nempilo yabantu.Ukwengeza, ukugaywa kabusha kwephepha elishisayo kuba nzima ukuba khona kwe-BPA namanye amakhemikhali, okwenza kube mancane amathuba okuthi ligaywe kabusha kunezinye izinhlobo zephepha.
Ukubhekana nomthelela wemvelo wephepha elishisayo, kunezinyathelo ezimbalwa ongazithatha.Enye indlela yokwenza lokhu ukunciphisa ukusetshenziswa kwephepha elishisayo ngokukhetha amarisidi e-electronic kanye nemibhalo yedijithali noma nini lapho kunokwenzeka.Lokhu kusiza ukunciphisa isidingo sephepha elishisayo futhi kunciphise umthelela wemvelo ohlobene.Ukwengeza, kungenziwa imizamo yokuthuthukisa ezinye izimbotshana zephepha elishisayo ezingenawo amakhemikhali ayingozi, okuzenza ziphephe kokubili ukusetshenziswa komuntu nendawo ezungezile.
Ukwengeza, ukulahlwa okufanele kanye nokugaywa kabusha kwephepha elishisayo kubalulekile ukuze kuncishiswe umthelela wawo endaweni ezungezile.Amabhizinisi nabathengi bangathatha izinyathelo zokuqinisekisa ukuthi iphepha elishisayo lilahlwa ngendlela enciphisa ukulimala okungaba khona emvelweni.Lokhu kungase kuhlanganise ukuhlukanisa iphepha elishisayo kweminye imifudlana yemfucuza kanye nokusebenza ngezindawo zokugaywa kabusha ezinamandla okuphatha iphepha elishisayo kanye namakhemikhali ahlobene nawo.
Kafushane, ngenkathi iphepha elishisayo linikeza ukunethezeka nokusebenza ezinhlotsheni zezinhlelo zokusebenza, umthelela walo endaweni ezungezile awunakushaywa indiva.Ukusetshenziswa kwamakhemikhali afana ne-BPA ekukhiqizweni kwawo kanye nezinselelo ezihambisana nokulahlwa kwawo kuphakamise ukukhathazeka mayelana nokulimala okungenzeka kwawo emvelweni.Umthelela wemvelo wephepha elishisayo ungancishiswa ngokunciphisa ukusetshenziswa kwalo, ukuthuthukisa ezinye izindlela eziphephile, nokusebenzisa izindlela ezifanele zokulahla nokugaywa kabusha, ngaleyo ndlela kube nesandla ezindleleni ezizinzile zokukhiqiza nokusetshenziswa.
