Thermal printers anoshandiswa zvakanyanya, asi havasi vese vanoziva mashandiro avanoita.Kusanganiswa kwethermal printeruye bepa rinopisa rinogona kugadzirisa zvatinoda zuva nezuva kudhinda.Saka chidhinda chinopisa chinoshanda sei?
Kazhinji, semiconductor heat element inoiswa pamusoro wakadhindwa weprinta yekupisa.Musoro wekudhinda uchapisa kana uchishanda.Mushure mekusangana nepepa rinopisa, muenzaniso unogona kudhindwa.Pepa rinopisa rakafukidzwa nejira refirimu rakajeka.Thermal printersvane zvaungasarudza.Pepa rinopisa rinopisa pane imwe nzvimbo, uye kuburikidza nekupisa, kemikari inogadzirwa inogadzirwa mufirimu kuti ibudise mufananidzo, musimboti wakafanana nemuchina wefax.Iwo maheater anodzorwa zvine mutsindo neprinta muchimiro cheskweya dots kana mitsetse.Kana ichityairwa, graphic inoenderana neinodziya element inogadzirwa pabepa rinopisa.
Thermal bepa imhando yakakosha yemapepa akavharidzirwa ane chimiro chakafanana nebepa jena rakajairika.Kumusoro kwebepa rinopisa kwakatsetseka uye kunogadzirwa nebepa rakajairwa sechigadziko chepepa, uye musara wekupisa unonzwa chromophoric layer wakaputirwa pamusoro pebepa rakajairika.Inonzi leuco dye), iyo isina kuparadzaniswa ne microcapsules, uye kemikari inogadzirisa iri mu "latent" mamiriro.Kana bepa rinopisa richisangana nemusoro unopisa unodhinda, mugadziri weruvara uye dhayi yeleuco panzvimbo iyo inodhinda musoro inodhinda inobata uye inoshandura ruvara kuita mifananidzo nezvinyorwa.
Apo pepa rinopisa rinoiswa munzvimbo inopfuura 70 ° C, iyo inopisa inopisa inotanga kuchinja ruvara.Chikonzero chekuchinja kwayo kunotangawo kubva pakuumbwa kwayo.Pane zvikamu zviviri zvikuru zvinopisa zvinopisa mumapepa ekupisa: imwe inonzi leuco dye kana leuco dye;imwe yacho inogadzira mavara.Iri rudzi rwebepa rinopisa rinodaidzwawo kuti maviri-chikamu chemakemikari mhando thermal rekodha bepa.
Inonyanya kushandiswa sedhayi dzeleuco ndeidzi: crystal violet lactone (CVL) ye trityl phthalide system, fluoran system, isina ruvara benzoylmethylene blue (BLMB) kana spiropyran system.Inowanzo shandiswa seanovandudza mavara ndeaya: para-hydroxybenzoic acid uye esters ayo (PHBB, PHB), salicylic acid, 2,4-dihydroxybenzoic acid kana anonhuwirira sulfone nezvimwe zvinhu.
Kana bepa rinopisa richipisa, dhayi yeleuco uye mugadziri anobata kemikari kuti abudise ruvara, saka kana bepa rinopisa richishandiswa kugamuchira masaini pamushini wefax kana kudhinda zvakananga nethermal printer, mifananidzo uye zvinyorwa zvinoratidzwa.Sezvo kune mhando dzakawanda dzedhayi dzeleuco, ruvara rwerunyoro rwunoratidzwa rwakasiyana, kusanganisira bhuruu, pepuru, dema zvichingodaro.
