Sivame ukukhuluma ngokuphrinta, ngokusebenzisa indlela ethile yokudlulisa uyinki endaweni ethile yephepha, ukuze sifune ukuthola amagama noma ihluzo.
Amakhemikhali akha iphepha awakutholi ukukhanya kwanoma yimuphi umbala kakhulu, ngakho lapho ukukhanya kuvela ebusweni bephepha nasemehlweni ethu, sikubona kumhlophe.
I-pigment noma udayi kuyinki udonsa okunye noma konke ukukhanya okubonakalayo, ukuze kuthi lapho uyinki ufakwa ebusweni bephepha, ingaphezulu lephepha elimhlophe liba nemibala.
Izinhlobo eziyinhloko zamaphrinta esiwasebenzisa ekhaya noma ehhovisi amaphrinta e-inkjet namaphrinta we-laser.
Ngokungafani namaphrinta ka-inkjet, afafaza amaconsi kayinki amancane ephepheni, amaphrinta e-laser adonsela ama-toner esigubhuni esilula futhi awadlulisele ephepheni ngendlela eheha i-electrostatic.
Nokho, irisidi aliphrintwa ngale ndlela.Iphrintwa ohlotsheni olukhethekile lwephepha, olubizwa nge-thermal paper.
Uma kuqhathaniswa nephepha elivamile, iphepha le-thermosensitive linembozo encane ebusweni balo, eliqukethe amakhemikhali athile abizwa ngokuthi odayi be-cryptic.
Udayi oyimpumputhe ngokwawo awunambala, ngakho-ke iphepha elishisayo elisanda kuthengwa libukeka limhlophe njengephepha elivamile.
Nokho, lapho izimo ezifanele zifinyelelwa, zisabela ngamakhemikhali, futhi izinto ezintsha zimunca ukukhanya okubonakalayo, futhi sibona umbala.
Izinto eziningi, njenge-crystalline violet lactone, nakuba ngokwemvelo zingenambala, ziba nsomi lapho kune-asidi.
Okusho ukuthi, uma siphrinta ephepheni le-thermosensitive, inki ayigcinwa kuphrinta, isivele isephepheni.

Isithombe
Umfanekiso 1 I-Crystalline violet lactone izoshintsha isuke ekubeni nsomi ibe nsomi lapho kukhona izinto ezine-asidi, futhi izophinde ingabi nambala futhi uma kukhona izinto ezine-alkaline.

Kodwa odayi be-cryptic njenge-crystallactone, esabela kalula nge-acids, baqinile ekamelweni lokushisa, futhi ama-molecule avaliwe endaweni.
Uma ubhekene ne-asidi nayo eqinile, ningahlala ndawonye isikhathi eside ekamelweni lokushisa, ngisho noma nisondelene.
Ngakho-ke, singathatha laba odayi abamnyama, abaqinile ekamelweni lokushisa, futhi sigaye okuqinile kwenye into ene-asidi ibe yimpushana, siyixube futhi siyigcobe ebusweni bephepha, bese sithola iphepha elishisayo.
Ezingeni lokushisa lasekamelweni, iphepha elishisayo libukeka njengephepha elivamile;
Ngokushesha lapho izinga lokushisa likhuphuka, udayi omnyama kanye ne-asidi kuyancibilika kube uketshezi, futhi ama-molecule ahambayo mahhala ahlangana futhi aphendule ngokushesha, ngakho iphepha elimhlophe libonisa umbala ngokushesha.
Yilapho iphepha le-thermosensitive lithola khona igama -- livele lishise ngokwanele ukushintsha umbala.
Ngephepha elishisayo, uma ufuna ukuphrinta umbhalo noma ihluzo endaweni yayo, udinga futhi iphrinta ekhethekile, okuyiphrinta eshisayo.
Uma kwenzeka udiliza iphrinta eshisayo, uzothola ukuthi ingaphakathi layo lilula kakhulu: ayikho i-cartridge kayinki.Izingxenye eziyinhloko yisigubhu kanye nekhanda lokuphrinta.
Iphepha elishisayo elisetshenziselwa ukuphrinta amarisidi ngokuvamile lenziwa ngemiqulu.
Uma umqulu wephepha elishisayo ufakwa kuphrinta, ishayelwa phambili ngerola bese ihlangana nekhanda lokuphrinta.
Kunezinto eziningi ezincane ze-semiconductor ebusweni bekhanda lokuphrinta ezishisisa izindawo ezithile zephepha ngokwamagama noma ihluzo esifuna ukuziphrinta.
Ngesikhathi sokuxhumana phakathi kwephepha elishisayo nekhanda lokuphrinta, izinga lokushisa eliphezulu elikhiqizwa ikhanda eliphrintayo lenza idayi ne-asidi engaphezulu kwephepha elishisayo incibilike ibe uketshezi futhi isabele ngamakhemikhali, ngaleyo ndlela ingaphezulu lephepha livela izinhlamvu noma ihluzo. .
Idonswe ngerola, irisidi yokuthenga iyaphrintwa.
Isithombe
Umfanekiso 2 Umgomo wokusebenza wephrinta eshisayo: iphepha elishisayo liya phambili liqhutshwa isigubhu.Uma ihlangana nekhanda lokuphrinta, ukushisa okukhiqizwa yikhanda lokuphrinta kuncibilikisa udayi ne-asidi ebusweni bephepha elishisayo, futhi lezi ezimbili zisabela ngamakhemikhali ukuze zikhiqize umbala.

Kungani amabhizinisi esebenzisa amaphepha ashisayo namaphrinta ashisayo ukuze aphrinte amarisidi okuthenga, kunokuphrinta i-laser noma amaphrinta e-inkjet ajwayelekile?
Okokuqala, amaphrinta we-laser noma we-inkjet adinga amadivayisi ayinkimbinkimbi ukuze adlulisele uyinki noma i-toner ukusuka kuphrinta ukuya ephepheni.Womabili amaphrinta makhulu futhi ngokuvamile asebenzisa i-alternate current njengamandla awo.
Amabhizinisi ngokuvamile adinga amaphrinta amancane, ikakhulukazi lapho ethengisa izimpahla ngaphandle noma ngamathuluzi ezokuthutha njengezindiza nezitimela, ukuthwala amaphrinta asindayo ukuze aphrinte amarisidi kumakhasimende ngokusobala akusebenzi.
Okwesibili, iphrinta ye-laser noma ye-inkjet yokushintsha amakhatriji kayinki noma i-toner ngokuvamile idla isikhathi futhi inzima, uma ilibazisa ukuphuma kwekhasimende, nayo engabaza kakhulu ukubona ibhizinisi nabathengi.
Lezi zinkinga zingaxazululwa ngokusebenzisa amaphrinta ashisayo nephepha elishisayo esikhundleni sama-lasers noma amaphrinta we-inkjet.
Ngenxa yokuthi uyinki usuvele ugcinwe ephepheni, amaphrinta ashisayo awadingi izakhiwo eziyinkimbinkimbi ukuze agcine futhi adlulise uyinki futhi angaba mancane kakhulu.
Futhi inamandla ebhethri, okuyenza ifaneleke ukuba amabhizinisi ayiphathe, ikakhulukazi lapho engaphandle noma ezokuthutha, ukuphrinta amarisidi kumakhasimende.
Ngenxa yokwakhiwa kwayo okulula, iphrinta eshisayo nayo kulula ukuyinakekela, futhi abasebenzisi akudingeki bakhathazeke ngokufaka ama-cartridges kayinki.Bangakwazi ukufaka esikhundleni somqulu omusha wephepha elishisayo ngokushesha nje lapho iphepha seliphelile.Lokhu kuqinisekisa ukuthi amakhasimende awalahlekelwa isikhathi esiningi kakhulu.
Ngaphezu kwalokho, isivinini sokuphrinta sephrinta esishisayo, umsindo ophansi, ofaneleka kakhulu ukusetshenziswa enxanxatheleni yezitolo.
Ngenxa yalezi zinzuzo, ukuphrinta okushisayo akuyona nje indlela ekhethwayo yokuphrinta amarisidi okuthenga, kodwa futhi kuvame ukusetshenziselwa ukuphrinta amathikithi, amalebula ngisho namafeksi.
Iphepha le-Thermosensitive nalo linesici esikhulu, okungukuthi ukubhala kudokhumenti ephrintiwe kuzonyamalala ngokuhamba kwesikhathi.
Ukufiphala kwenzeka futhi ngenxa yodayi abahlukile abasetshenziswa ephepheni elishisayo.
Njengoba sishilo ekuqaleni, udayi we-cryptic omboza iphepha elishisayo awunambala ekamelweni lokushisa, futhi uba esinye isakhiwo esinombala ngenxa yokusabela kwamakhemikhali ekushiseni okuphezulu.
Kodwa-ke, isakhiwo esisha asizinzile kangako, futhi ngaphansi kwezimo ezifanele sibuyela emuva esakhiweni saso sangaphambilini esingenambala.
Isibonelo, i-crystalline violet lactone, njengoba sishilo ekuqaleni, iphenduka isakhiwo esinemibala lapho kukhona into ene-asidi, futhi lesi sakhiwo esinombala sibuyela esimweni esingenambala lapho kukhona into ene-alkali.
Ngemva kokugcinwa kwerisidi ephrintiwe, ingase ihlangane nezinhlobonhlobo zamakhemikhali endaweni.Ingase futhi ichayeke elangeni noma emazingeni okushisa aphakeme, okungase kubangele udayi osephepheni elishisayo ubuyele esimweni sawo esingenambala, kushintshe irisidi.
Ukuze kuxazululwe le nkinga, abakhiqizi abaningi bamaphepha ashisayo bengeza ungqimba olwengeziwe lwesivikelo phezu koqweqwe lukadayi ukuze banciphise ukuthintana kukadayi namanye amakhemikhali futhi benze imibhalo enyatheliswe ephepheni elishisayo ihlale isikhathi eside.
Kodwa le ndlela izokwandisa izindleko zephepha elishisayo, ngakho-ke kuzoba namabhizinisi azoqhubeka nokusebenzisa ungqimba oluvikelayo lwephepha elivamile elishisayo.
Uma ukhathazekile ngokuthi irisidi yakho izonyamalala ngokuhamba kwesikhathi, kuhlale kuwumqondo omuhle ukukopisha noma ukuskena irisidi yakho.
Eminyakeni yamuva nje, iphepha le-thermosensitive liye labangela ukukhathazeka phakathi kwabathengi abaningi ngoba liqukethe i-bisphenol A.
I-Bisphenol A iyinto ene-asidi, ngakho-ke isetshenziswa ephepheni le-thermosensitive lapho ihlangana nodayi abamnyama emazingeni okushisa aphezulu ukuze ikhiqize umbala.
Ngaphezu kwalokho, i-bisphenol A isetshenziswa kakhulu njengezinto ezingavuthiwe ukwenza amapulasitiki athile noma okokunamathela.
Ngakho indlela eyinhloko i-BPA engena ngayo emzimbeni yilapho ufaka ukudla kulezi zitsha, amanani amancane e-BPA angena emzimbeni kanye nokudla.
Kodwa eminyakeni yamuva nje, ucwaningo luye lwabonisa ukuthi ukuchayeka kumanothi abhalwe ephepheni elingezwani nokushisa kungase kubangele ukuthi i-BPA ingene emzimbeni.
Olunye ucwaningo lwakamuva, isibonelo, luthole ukuthi amazinga e-BPA emchameni anda ngemva kokuchayeka isikhathi eside ephepheni elingezwani nokushisa.
Ngenxa yokuthi ukwakheka kwamakhemikhali e-bisphenol A kufana ne-estradiol, i-estrogen eyinhloko ekhiqizwa umzimba, kukhona ukukhathazeka ukuthi ingase iphazamise ukukhishwa kwe-endocrine evamile futhi yandise ingozi yezifo eziningi.
Kodwa-ke, kubalulekile ukuveza ukuthi ukugxila kwe-BPA emzimbeni ngokudla kanye nephepha elishisayo liphansi kakhulu, ngakho-ke kunzima ukuqinisekisa imiphumela yezempilo ye-BPA kubantu.
Kodwa-ke, nakuba i-BPA ingavinjelwe okwamanje ekukhiqizeni iphepha elishisayo, abakhiqizi abaningi sebeqalile ukusebenzisa amanye ama-asidi esikhundleni salokho.
Uma ukhathazekile ngenani elincane le-BPA elingena ohlelweni lwakho kusukela ekuthinteni amarisidi, Isinyathelo sokuphepha okungenzeka kakhulu ukugcina amarisidi ewodwa ngokushesha ngangokunokwenzeka ngaphandle kokuwathinta, nokugeza izandla zakho ngemva kokuthinta amarisidi.
Yiqiniso, ukushintsha amarisidi ephepha ufake awe-elekthronikhi kungase kube nempilo futhi kungayingcolisi imvelo.
