Ifotopolymerization ye-UV, ekwabizwa ngokuba kukunyanga ngemitha okanye ukunyangwa kwe-UV, bubuchwephesha obuguqula umdlalo obuguqula iinkqubo zokuvelisa phantse iikota ezintathu zenkulungwane. Le nkqubo isungulayo isebenzisa amandla e-ultraviolet ukuqhuba ukudibanisa ngaphakathi kwezixhobo ezenziwe nge-UV, ezinjengee-inki, iingubo, izinto zokuncamathelisa, kunye ne-extrusions.
Enye yeenzuzo eziphambili zokunyanga kwe-UV kukukwazi ukuvelisa iipropathi zezinto ezinqweneleka kakhulu ezinesantya esiphezulu, ufakelo oluncinci lweenyawo. Oku kuthetha ukuba imathiriyeli inokuguqulwa ukusuka kwimeko emanzi, emanzi ukuya kwimo eqinileyo, imeko eyomileyo phantse ngoko nangoko. Olu tshintsho olukhawulezayo lufezekiswa ngaphandle kwemfuneko yabathwali bamanzi, abasetyenziswa ngokuqhelekileyo kumanzi aqhelekileyo kunye ne-solvent-based formulations.
Ngokungafaniyo neenkqubo zokomisa ngokwesiko, ukunyangwa kwe-UV akusuki nje kube ngumphunga okanye ukomise izinto. Endaweni yoko, ifumana ukusabela kweekhemikhali ezenza amaqhina aqinileyo, ahlala ixesha elide phakathi kweemolekyuli. Oku kubangela ukuba izinto ezomelele ngendlela emangalisayo, ezikwaziyo ukumelana nomonakalo wekhemikhali kunye nemozulu, kwaye zineempawu ezinqwenelekayo zomphezulu ezinje ngokuqina kunye nokumelana nokutyibilika.
Ngokwahlukileyo, amanzi emveli kunye ne-solvent-based formulations ixhomekeke kubathwali be-liquid ukuququzelela ukusetyenziswa kwezixhobo kwiindawo. Xa sele ifakiwe, into ephathwayo kufuneka iguqulwe ibe ngumphunga okanye yomiswe kusetyenziswa ii-oveni ezidla amandla kunye neetonela zokomisa. Le nkqubo inokushiya ngasemva intsalela yezinto eziqinileyo ezithanda ukukrwela, ukonakaliswa, kunye nomonakalo wemichiza.
Ukunyangwa kwe-UV kunika iingenelo ezininzi ezibalulekileyo kwiinkqubo zokomisa ngokwesiko. Ngolunye, iphelisa imfuno yee-ovens ezithatha amandla kunye nokumisa iitonela, ukunciphisa ukusetyenziswa kwamandla kunye nefuthe lokusingqongileyo. Ukongeza, ukunyanga kwe-UV kuphelisa imfuno ye-volatile organic compounds (VOCs) kunye nezingcolisi zomoya ezinobungozi (HAPs), okwenza kube yinto enokusingqongileyo.
Isishwankathelo, ukunyangwa kwe-UV yitekhnoloji esebenza kakuhle kwaye esebenzayo ebonelela ngeenzuzo ezininzi kubavelisi. Ikhono layo lokuvelisa izinto ezisemgangathweni ophezulu ngesantya kunye nokuchaneka kwenza kube yinto efanelekileyo yokukhetha uluhlu olubanzi lwamashishini. Ngokusebenzisa amandla okunyanga kwe-UV, abavelisi banokuvelisa izixhobo ezinokuphuculwa kokusebenza, imbonakalo, kunye nokuqina, ngelixa behlisa ifuthe labo lokusingqongileyo.
