Osindikiza otentha amagwiritsidwa ntchito kwambiri, koma si aliyense amene amadziwa momwe amagwirira ntchito.Kuphatikiza kwachosindikizira chotenthandi mapepala otentha amatha kuthetsa zosowa zathu zatsiku ndi tsiku zosindikiza.Ndiye chosindikizira chamafuta chimagwira ntchito bwanji?
Nthawi zambiri, chotenthetsera cha semiconductor chimayikidwa pamutu wosindikiza wa chosindikizira chamafuta.Mutu wosindikizira udzatentha pamene ukugwira ntchito.Pambuyo pokhudzana ndi mapepala otentha, chitsanzo chikhoza kusindikizidwa.Pepala lotentha limakutidwa ndi filimu yowonekera.Makina osindikizira otenthakhalani ndi zosankha.Mapepala otentha amatenthedwa pamalo enaake, ndipo kupyolera mu kutentha, mankhwala amapangidwa mufilimu kuti apange fano, mfundoyi ndi yofanana ndi makina a fax.Zowotchera zimayendetsedwa bwino ndi chosindikizira mu mawonekedwe a madontho apakati kapena mizere.Poyendetsedwa, chithunzi chofanana ndi chotenthetsera chimapangidwa papepala lotentha.
Pepala lotenthedwa ndi pepala lapadera lopangidwa ndi pepala lomwe mawonekedwe ake amafanana ndi pepala loyera wamba.Pamwamba pa pepala lotentha ndi losalala ndipo amapangidwa ndi mapepala wamba ngati maziko a mapepala, ndipo chigawo cha chromophoric chosamva kutentha chimakutidwa pamwamba pa pepala wamba.Imatchedwa leuco dye), yomwe siimasiyanitsidwa ndi ma microcapsules, ndipo zotsatira za mankhwala zimakhala mu "latent" state.Pamene pepala lotentha likumana ndi mutu wosindikizira wotentha, wopanga mtundu ndi utoto wa leuco pamalo omwe mutu wosindikizira umakhudzidwa ndi mankhwala ndikusintha mtundu kuti ukhale zithunzi ndi malemba.
Pamene pepala lotenthetsera liyikidwa pamalo okwera pamwamba pa 70 ° C, kutentha kumayamba kusintha mtundu.Chifukwa cha kusinthika kwake kumayambiranso pakupanga kwake.Pali zigawo ziwiri zazikulu zotenthetsera pamapepala otenthetsera: imodzi ndi utoto wa leuco kapena utoto wa leuco;winayo ndi wopanga mitundu.Mtundu uwu wa pepala matenthedwe amatchedwanso awiri chigawo mankhwala mtundu matenthedwe kujambula pepala.
Nthawi zambiri amagwiritsidwa ntchito ngati utoto wa leuco ndi: crystal violet lactone (CVL) ya trityl phthalide system, fluoran system, colorless benzoylmethylene blue (BLMB) kapena spiropyran system.Zomwe zimagwiritsidwa ntchito ngati mankhwala opangira utoto ndi: para-hydroxybenzoic acid ndi esters (PHBB, PHB), salicylic acid, 2,4-dihydroxybenzoic acid kapena zonunkhira za sulfone ndi zinthu zina.
Pepala lotenthetsera likatenthedwa, utoto wa leuco ndi wopanga zinthuzo zimagwira ntchito ndi mankhwala kuti apange mtundu, kotero pamene pepala lotenthetsera likugwiritsidwa ntchito polandira chizindikiro pa makina a fax kapena kusindikiza mwachindunji ndichosindikizira chotentha, zithunzi ndi zolemba zikuwonetsedwa.Popeza pali mitundu yambiri ya utoto wa leuco, mtundu wa zolembedwa pamanja ndi wosiyana, kuphatikizapo buluu, wofiirira, wakuda ndi zina zotero.
