Amaphrinta ashisayo asetshenziswa kakhulu, kodwa akuwona wonke umuntu owaziyo ukuthi asebenza kanjani.Inhlanganisela yeiphrinta ezishisayokanye nephepha elishisayo lingaxazulula izidingo zethu zokunyathelisa zansuku zonke.Ngakho-ke iphrinta eshisayo isebenza kanjani?
Ngokuvamile, isici sokushisa se-semiconductor sifakwa ekhanda lokuphrinta lephrinta eshisayo.Ikhanda lokuphrinta lizoshisa uma lisebenza.Ngemva kokuxhumana nephepha elishisayo, iphethini ingaphrintwa.Iphepha elishisayo limbozwe ungqimba lwefilimu esobala.Amaphrinta ashisayoube nezinketho.Iphepha elishisayo lishiswa endaweni ethile, futhi ngokushisa, ukusabela kwamakhemikhali kukhiqizwa efilimini ukuze kukhiqize isithombe, isimiso sifana nomshini wefeksi.Izifudumezi zilawulwa ngokunengqondo iphrinta ngendlela yamachashazi ayisikwele noma imicu.Uma iqhutshwa, isithombe esihambisana nesici sokushisa sikhiqizwa ephepheni elishisayo.
Iphepha elishisayo liwuhlobo olukhethekile lwephepha elicutshunguliwe elihlanganiswe ukubukeka kwalo kufana nephepha elimhlophe elijwayelekile.Ingaphezulu lephepha elishisayo libushelelezi futhi lenziwe ngephepha elivamile njengesisekelo sephepha, futhi ungqimba lwe-chromophoric oluzwela ukushisa lumbozwe phezu kwephepha elivamile.Ibizwa ngokuthi i-leuco dye), engahlukaniswa ngama-microcapsules, futhi ukusabela kwamakhemikhali kusesimweni "esicashile".Lapho iphepha elishisayo lihlangana nekhanda eliphrintiwe elishisayo, umthuthukisi wombala kanye nodayi we-leuco endaweni lapho ikhanda lokuphrinta eliphrinta khona lisabela ngokwekhemikhali futhi lishintshe umbala ukwenza izithombe nemibhalo.
Lapho iphepha elishisayo libekwe endaweni engaphezu kuka-70 ° C, ukugqoka okushisayo kuqala ukushintsha umbala.Isizathu sokushintsha kombala kwawo naso siqala ekwakhiweni kwawo.Kunezingxenye ezimbili eziyinhloko ezishisayo ekugqokeni kwephepha elishisayo: enye idayi ye-leuco noma idayi ye-leuco;omunye unjiniyela wombala.Lolu hlobo lwephepha elishisayo lubizwa nangokuthi iphepha lokuqopha lezingxenye ezimbili zamakhemikhali.
Okuvame ukusetshenziswa njengodayi be-leuco yilezi: i-crystal violet lactone (CVL) ye-trityl phthalide system, isistimu ye-fluoran, i-benzoylmethylene eluhlaza okwesibhakabhaka engenambala (BLMB) noma uhlelo lwe-spiropyran.Okuvame ukusetshenziswa njengama-ejenti athuthukisa umbala yilezi: i-para-hydroxybenzoic acid nama-esters ayo (PHBB, PHB), i-salicylic acid, i-2,4-dihydroxybenzoic acid noma ama-sulfone anuka kamnandi nezinye izinto.
Lapho iphepha elishisayo lishiswa, udayi we-leuco kanye nonjiniyela basabela ngamakhemikhali ukuze bakhiqize umbala, ngakho-ke lapho iphepha elishisayo lisetshenziselwa ukwamukela amasignali emshinini wefeksi noma ukuphrinta ngokuqondileiphrinta ezishisayo, ihluzo nombhalo kuyavezwa.Njengoba kunezinhlobo eziningi zodayi be-leuco, umbala wombhalo wesandla obonisiwe uhlukile, kuhlanganise noluhlaza okwesibhakabhaka, onsomi, omnyama nokunye.
