Abashicileli be-Thermal basetyenziswa kakhulu, kodwa ayinguye wonke umntu owaziyo ukuba basebenza njani.Indibaniselwano yeumshicileli we-thermalkunye nephepha le-thermal linokusombulula iimfuno zethu zokushicilela zemihla ngemihla.Ke ingaba umshicileli we-thermal usebenza njani?
Ngokuqhelekileyo, i-semiconductor yokufudumala ifakwe kwintloko yoshicilelo lomshicileli we-thermal.Intloko yoshicilelo iya kutshisa xa isebenza.Emva kokunxibelelana nephepha le-thermal, iphethini inokuprintwa.Iphepha le-thermal ligqunywe ngoluhlu lwefilimu ecacileyo.Iiprinta ezishushuube neenketho.Iphepha le-thermal lifudumala kwindawo ethile, kwaye ngokufudumeza, ukuphendulwa kweekhemikhali kuveliswa kwifilimu ukuvelisa umfanekiso, umgaqo ufana nomatshini wefeksi.Izifudumezi zilawulwa ngengqiqo ngumshicileli ngendlela yamachaphaza angama-square okanye imicu.Xa iqhutywa, umzobo ohambelana nesixhobo sokufudumala senziwa kwiphepha le-thermal.
Iphepha le-Thermal luhlobo olukhethekileyo lwephepha elicwangcisiweyo elicwangcisiweyo elibonakala lifana nephepha elimhlophe eliqhelekileyo.Umphezulu wephepha le-thermal ligudile kwaye lenziwe ngephepha eliqhelekileyo njengesiseko sephepha, kwaye umaleko we-chromophoric ongevani nobushushu ugqunywe kumphezulu wephepha eliqhelekileyo.Ibizwa ngokuba yi-leuco dye), engahlukaniswanga yi-microcapsules, kwaye ukuphendulwa kweekhemikhali kukwimeko "efihlakeleyo".Xa iphepha le-thermal lidibana nentloko yokushicilela eshushu, umqambi wombala kunye nedayi ye-leuco kwindawo apho intloko yokushicilela iprinta i-chemically isabela kwaye iguqule umbala ukwenza imifanekiso kunye neetekisi.
Xa iphepha le-thermal libekwe kwindawo engaphezulu kwe-70 ° C, i-thermal coating iqala ukutshintsha umbala.Isizathu sokutshintsha kombala kwaso siqala ekwenziweni kwayo.Kukho izinto ezimbini eziphambili ze-thermal kwi-thermal paper coating: enye yidayi ye-leuco okanye idayi ye-leuco;omnye ngumphuhlisi wombala.Olu hlobo lwephepha le-thermal lukwabizwa ngokuba yi-two-component chemical type paper recording paper.
Ngokuqhelekileyo zisetyenziswa njengedayi ze-leuco zezi: i-crystal violet lactone (CVL) ye-trityl phthalide system, inkqubo ye-fluoran, i-benzoylmethylene blue engenambala (BLMB) okanye inkqubo ye-spiropyran.Ngokuqhelekileyo zisetyenziswa njengeejenti eziphuhlisa umbala zezi: i-para-hydroxybenzoic acid kunye ne-esters yayo (PHBB, PHB), i-salicylic acid, i-2,4-dihydroxybenzoic acid okanye i-sulfones enamakha kunye nezinye izinto.
Xa iphepha le-thermal lifudunyezwa, idayi ye-leuco kunye nomphuhlisi basabela ngokwekhemikhali ukuvelisa umbala, ngoko xa iphepha le-thermal lisetyenziselwa ukufumana imiqondiso kumatshini wefeksi okanye ukushicilela ngokuthe ngqoumshicileli we-thermal, imizobo kunye nokubhaliweyo kuyavezwa.Ekubeni zininzi iintlobo zedayi zeleuco, umbala wombhalo wesandla obonisiweyo wahlukile, kuquka oblowu, omfusa, omnyama njalo njalo.
