Kutheni le nto iphepha le-thermal linokushicilela ngaphandle kwe-inki okanye iribhoni? Kungenxa yokuba kukho ukudibana okuncinci kumphezulu wephepha le-thermal, elineekhemikhali ezikhethekileyo ezibizwa ngokuba yiLeuco Dyes. I-leuco dyay ngokwayo ingenabala, kwaye kubushushu begumbi, iphepha elithe tyali alikho lahlukile kwiphepha eliqhelekileyo.
Nje ukuba iqondo lobushushu likhuphuka, i-leuco dyays kunye nezinto ze-acidic zinyibilika zibe yi-falls enye, kwaye iimolekyuli ezinokuhamba ngendlela edibana ngokukhawuleza xa zivela kwiPhepha leNgcaciso yoMgaqo-nkqubo. Kungenxa yeso sizathu iphepha le-thu - kuphela xa iqondo lobushushu lifikelela kwinqanaba elithile kuya kutshintsha umbala.
Ngamanye amagama, xa siprinta liphepha le-thermal, i-inki ayigcinwanga kwiprinta, kodwa igqityiwe ephepheni. Ngephepha le-thermal, ukuba ufuna ukuprinta okubhaliweyo okanye imizobo kumphezulu wayo, ufuna umshicileli okhethekileyo wokusebenzisana, ongumshicileli we-thermal.
Ukuba unethuba lokukhuphela umshicileli we-thermal, uyakufumanisa ukuba ulwakhiwo lwayo lwangaphakathi lulula kakhulu: Akukho nqwelomoya i-inki, kwaye izinto eziphambili yi-roller kunye nentloko yokuprinta.
Iphepha le-thermal elisetyenziselwa ukuprinta iirisithi lihlala lenziwe ukuba liqengqele. Xa i-qubring yamaphepha e-thermal ifakwe kwiprinta, iya kuthunyelwa phambili yi-roller kwaye inxibelelane nentloko yokuprinta.
Zininzi izinto ezincinci ze-semicondcuctor kumphezulu wentloko yokuprinta, enokutshisa iindawo ezithile zephepha ngokwesicatshulwa okanye imizobo esifuna ukuyiprinta.
Okwangoku xa iphepha le-thermal liza kudibana nentloko yokuprinta, iqondo lobushushu eliveliswa yi-DEE libangela idayi yephepha le-shirmal ukuze inyibilikisi, ukuze imigca okanye imizobo ivele kumphezulu wephepha. Iqhutywa yiRoller, irisithi yokuthenga ishicilelwa.
