Enkathini ebuswa ubuchwepheshe bedijithali, ukusimama kwephepha elishisayo kungase kubonakale njengesihloko esingabalulekile.Kodwa-ke, umthelela wemvelo wokukhiqizwa nokusetshenziswa kwephepha elishisayo kuyindaba yokukhathazeka, ikakhulukazi njengoba amabhizinisi nabathengi beqhubeka bethembele kulolu hlobo lwephepha ukuze bathole amarisidi, amalebula nezinye izinhlelo zokusebenza.
Iphepha le-thermal lisetshenziswa kakhulu ezimbonini ezahlukahlukene ngenxa yokunethezeka nokusebenza kahle kwezindleko.Ivamise ukusetshenziswa ezindaweni zokuthengisa ukuphrinta amarisidi, ekunakekelweni kwezempilo ukulebula amasampula, kanye nasezintweni zokuphrinta amalebula okuthumela.Nakuba iphepha elishisayo lisetshenziswa kakhulu, ukusimama kwalo sekucutshungulwe ngenxa yamakhemikhali asetshenziswa ekukhiqizeni kwalo kanye nezinselelo ezihambisana nokugaywa kabusha.
Okunye okukhathaza kakhulu mayelana nokusimama kwephepha elishisayo ukusetshenziswa kwe-bisphenol A (BPA) kanye ne-bisphenol S (BPS) ekunambeni kwalo.Lawa makhemikhali abaphazamisi be-endocrine abaziwayo futhi axhunyaniswe nemiphumela emibi yezempilo.Nakuba abanye abakhiqizi sebeshintshele ekukhiqizeni iphepha elishisayo elingenayo i-BPA, i-BPS, evame ukusetshenziswa esikhundleni se-BPA, iphinde yaphakamisa ukukhathazeka ngomthelela wayo ongaba khona empilweni yabantu kanye nemvelo.
Ukwengeza, ukugaywa kabusha kwephepha elishisayo kubangela izinselelo ezinkulu ngenxa yokuba khona kwezingubo zamakhemikhali.Izinqubo zendabuko zokuphinda zigaywe kabusha kwephepha azilifanele iphepha elishisayo ngoba ukunamathela okushisayo kungcolisa i-pulp egaywe kabusha.Ngakho-ke, iphepha elishisayo livame ukuthunyelwa ezindaweni zokulahla imfucumfucu noma ezitshalweni zokushiswa, okubangela ukungcoliswa kwemvelo kanye nokuncipha kwezinsiza.
Uma kubhekwa lezi zinselele, imizamo iyaqhubeka yokubhekana nezinkinga zokusimama kwephepha elishisayo.Abanye abakhiqizi bahlola ezinye izimbotshana ezingenawo amakhemikhali ayingozi, ngaleyo ndlela banciphise umthelela wemvelo wokukhiqizwa kwephepha elishisayo.Ukwengeza, siphishekela inqubekelaphambili kubuchwepheshe bokugaywa kabusha ukuze sithuthukise izindlela zokuhlukanisa ngempumelelo ama-thermal coatings ephepheni, ngaleyo ndlela sivumele ukugaywa kabusha kwephepha elishisayo kanye nokunciphisa indawo yayo yemvelo.
Ngokombono wabathengi, kunezinyathelo ezingathathwa ukuze kuthuthukiswe ukusimama kwephepha elishisayo.Lapho kungenzeka khona, ukukhetha amarisidi e-elekthronikhi ngaphezu kwamarisidi aphrintiwe kungasiza ekunciphiseni isidingo sephepha elishisayo.Ukwengeza, ukukhuthaza ukusetshenziswa kwephepha elishisayo le-BPA- ne-BPS kungakhuthaza abakhiqizi ukuthi babeke phambili ukuthuthukiswa kwezinye izindlela eziphephile.
Esikhathini sedijithali, lapho ukuxhumana nge-elekthronikhi kanye nemibhalo sekuyinto evamile, ukusimama kwephepha elishisayo kubonakala sengathi kuphelile.Kodwa-ke, ukusetshenziswa kwayo okuqhubekayo ezinhlobonhlobo zezinhlelo zokusebenza kudinga ukuhlolisisa umthelela wayo kwezemvelo.Ngokubhekana nezindaba eziphathelene nokumbozwa kwamakhemikhali nezinselele zokuvuselela kabusha, iphepha elishisayo lingenziwa lizinze, ngokuhambisana nemigomo ebanzi yokuvikelwa kwemvelo nokusebenza kahle kwezinsiza.
Kafushane, ukusimama kwephepha elishisayo esikhathini sedijithali kuyindaba eyinkimbinkimbi edinga ukubambisana phakathi kwababambe iqhaza embonini, abenzi bezinqubomgomo kanye nabathengi.Umkhondo wemvelo wephepha elishisayo ungancishiswa ngokuphromotha ukusetshenziswa kwezingubo eziphephile kanye nokutshalwa kwezimali ekugayeni kabusha okuqanjwe kabusha.Njengoba sisebenzela ikusasa elisimeme, kubalulekile ukucabangela umthelela wezinto ezibonakala zivamile njengephepha elishisayo futhi sisebenzele ukunciphisa umthelela wazo endaweni ezungezile.
