Iibhokisi zemibala ezisetyenziselwa ukupakishwa kwemveliso kunye neebhokisi zokupakisha zokupakishwa kwezinto ezahlukeneyo zenziwaibhodi yeendlovu . Emva kokusikwa, ukuprinta kunye nokucutshungulwa okulandelayo, iba yibhokisi yethu yokupakisha imveliso.
Namhlanje, xa ukonwabela izinto eziphathekayo kuxatyiswa, abantu baneemfuno eziphezulu neziphezulu kumgangatho wekhadibhodi yokupakisha. Ibhodi yendlovu (ekwaziwa ngokuba yikhadibhodi emhlophe eqatywe okanyeFBB ) yimathiriyeli yokupakisha yodidi oluphezulu, kwaye inkangeleko yayo entle iye yaba lusukelo lwabantu. Nangona kunjalo, into etyheli yephepha lebhodi emhlophe egqunywe ngexesha lokusetyenziswa ichaphazela kakhulu ukubonakala kwepakethe yangaphandle. I-yellowing yekhadibhodi emhlophe ibhekisela kwinto yokuba ubumhlophe bemveliso buya kuncipha ukuya kwinqanaba elithile emva kwexesha elithile lokugcinwa okanye ukukhanya kwelanga.
Iziphumo zophando zamva nje zibonisa ukuba i-phenomenon ye-yellowing kukuba izinto ezingaphezulu kwebhodi yebhokisi yokugoqa isabela nge-oksijini emoyeni, etshintsha ukwakheka kweekhemikhali zezinto ezingaphezulu, ngaloo ndlela zichaphazela imbonakalo yabantu. Iqondo le-oxidation limisela ubuzaza bobutyheli.
Izinto ezichaphazela ukutyheli kweikhadibhodi emhlophe ikakhulu ibandakanya le miba ilandelayo: isiseko sebhodi emhlophe eqatywe, i-agent emhlophe ye-fluorescent, i-pigment yombala, i-adhesive enamathelayo, njl njl. misela eyona ndibaniselwano ilungileyo yokuncamathelisa, enokunciphisa ngempumelelo into etyheli yephepha lebhodi emhlophe; Izongezo, ezifana ne-nano-silicon-based oxides, iimveliso zeekhemikhali ezifana ne-UV absorbers kunye ne-antioxidants, ziya kunciphisa i-yellowing phenomenon yephepha elimhlophe elimhlophe; ukomeleza ukulawulwa kwemveliso yephepha lebhodi emhlophe kunye nokuthintela yonke imiba yokupakisha kunye neemeko zokugcina nazo ziyindlela efanelekileyo yokusombulula i-yellowing yekhadibhodi emhlophe.
Lawula zonke iinkqubo ezibandakanyekayo, ulungelelanisa kwaye ulungelelanise ukusebenza, kwaye umgangatho wekhadi elimhlophe eligqunyiweyo liya kuba linqanaba lokuqala.
