Peb feem ntau tham txog kev luam ntawv, yog los ntawm ib txoj hauv kev los hloov tus cwj mem mus rau ib cheeb tsam ntawm daim ntawv, yog li peb xav tau cov lus lossis cov duab kos.
Cov tshuaj uas tsim cov ntawv tsis nqus lub teeb ntawm cov xim ntau heev, yog li thaum lub teeb pom kev tawm ntawm daim ntawv thiab rau hauv peb lub qhov muag, peb pom nws dawb.
Cov xim los yog xim nyob rau hauv tus number case absorbs ib co los yog tag nrho cov pom lub teeb, yog li ntawd thaum tus number case yog siv rau ntawm daim ntawv, qhov saum npoo ntawm daim ntawv dawb yuav xim.
Hom tshuab luam ntawv tseem ceeb uas peb siv hauv tsev lossis hauv chaw ua haujlwm yog inkjet printers thiab laser printers.
Tsis zoo li cov tshuab luam ntawv inkjet, uas tshuaj tsuag me me ntawm tus number case rau ntawm daim ntawv, cov tshuab luam ntawv laser nyiam toners rau lub nruas nruas thiab xa mus rau hauv daim ntawv los ntawm electrostatic attraction.
Txawm li cas los xij, daim ntawv txais nyiaj tsis tau luam tawm li no.Nws yog luam tawm ntawm ib hom ntawv tshwj xeeb, hu ua thermal paper.
Piv nrog rau cov ntawv zoo tib yam, cov ntawv thermosensitive muaj cov txheej nyias nyias ntawm nws qhov chaw, uas muaj qee cov tshuaj tshwj xeeb hu ua cryptic dyes.
Lub qhov muag tsis pom nws tus kheej yog xim tsis muaj xim, yog li cov ntawv tshiab tau yuav thermal zoo li dawb li daim ntawv zoo tib yam.
Txawm li cas los xij, thaum cov xwm txheej zoo tau ntsib, lawv hnov mob chemical, thiab cov khoom tshiab absorbs pom lub teeb, thiab peb pom xim.
Ntau yam tshuaj, xws li crystalline violet lactone, txawm tias tsis muaj xim, tig liab doog nyob rau hauv muaj cov kua qaub.
Ntawd yog, thaum peb luam tawm ntawm daim ntawv thermosensitive, tus number case tsis khaws cia rau hauv lub tshuab luam ntawv, nws twb nyob rau ntawm daim ntawv.
Daim duab
Fig. 1 Crystalline violet lactone yuav hloov los ntawm tsis muaj xim mus rau xim liab nyob rau hauv lub xub ntiag ntawm acidic tshuaj, thiab yuav ua tsis muaj xim dua nyob rau hauv lub xub ntiag ntawm alkaline tshuaj.
Tab sis cryptic dyes xws li crystallactone, uas reacts yooj yim nrog acids, yog khoom nyob rau hauv chav tsev kub, thiab cov molecules raug kaw nyob rau hauv qhov chaw.
Yog tias koj tab tom cuam tshuam nrog cov kua qaub uas tseem yog ib qho khoom, koj tuaj yeem nyob ua ke ntev ntawm chav tsev kub, txawm tias koj nyob ze.
Yog li ntawd, peb tuaj yeem siv cov xim tsaus nti, uas yog cov khoom hauv chav sov, thiab zom cov khoom ntawm lwm cov kua qaub rau hauv cov hmoov zoo, sib tov thiab smear rau ntawm daim ntawv, thiab peb tau txais ib daim ntawv thermal.
Nyob rau hauv chav tsev kub, thermal ntawv zoo ib yam li daim ntawv li niaj zaus;
Thaum qhov kub nce siab, cov xim tsaus nti thiab cov kua qaub yaj mus rau hauv cov kua, thiab cov molecules dawb txav sib ntsib thiab hnov mob tam sim ntawd, yog li daim ntawv dawb sai sai pom cov xim.
Qhov no yog qhov uas cov ntawv thermosensitive tau txais nws lub npe - nws tsuas yog kub txaus los hloov xim.
Nrog cov ntawv thermal, yog tias koj xav luam cov ntawv lossis cov duab ntawm nws qhov chaw, koj kuj xav tau lub tshuab luam ntawv tshwj xeeb, uas yog lub tshuab luam ntawv thermal.
Yog tias koj puas tau tawg lub tshuab luam ntawv thermal, koj yuav pom tias nws sab hauv yog yooj yim heev: tsis muaj number case cartridge.Cov khoom tseem ceeb yog lub nruas thiab lub taub hau luam ntawv.
Cov ntawv thermal siv los luam cov ntawv txais nyiaj feem ntau yog ua hauv yob.
Thaum lub yob ntawm thermal ntawv muab tso rau hauv lub tshuab luam ntawv, nws yog tsav los ntawm cov menyuam thiab tuaj rau hauv kev sib cuag nrog lub taub hau luam ntawv.
Muaj ntau lub ntsiab lus me me nyob rau saum npoo ntawm lub taub hau luam ntawv uas ua kom sov ib qho chaw ntawm daim ntawv raws li cov lus lossis cov duab peb xav luam tawm.
Thaum lub sij hawm ntawm kev sib cuag ntawm cov ntawv thermal thiab lub taub hau luam ntawv, qhov kub thiab txias tsim los ntawm lub taub hau luam ntawv ua rau cov xim thiab cov kua qaub nyob rau saum npoo ntawm cov ntawv thermal yaj ua ke rau hauv cov kua thiab ua rau cov tshuaj lom neeg, yog li cov ntawv saum npoo zoo li cov cim lossis cov duab. .
Dripped los ntawm cov menyuam, ib daim ntawv txais yuav luam tawm.
Daim duab
Daim duab 2 Lub hauv paus ntsiab lus ua haujlwm ntawm lub tshuab luam ntawv thermal: cov ntawv thermal txav mus tom ntej uas tau tsav los ntawm lub nruas.Thaum nws los rau hauv kev sib cuag nrog lub taub hau luam ntawv, lub tshav kub tsim los ntawm lub taub hau luam ntawv melts cov xim thiab cov kua qaub rau ntawm daim ntawv thermal, thiab ob qho tib si tshuaj lom neeg los tsim cov xim.
Vim li cas cov lag luam siv cov ntawv thermal thiab cov tshuab luam ntawv thermal los luam cov ntawv txais nyiaj, ntau dua li cov tshuab luam ntawv laser lossis inkjet?
Ua ntej, laser lossis inkjet tshuab luam ntawv xav tau cov cuab yeej siv los hloov cov number case lossis toner los ntawm lub tshuab luam ntawv mus rau daim ntawv.Ob lub tshuab luam ntawv yog loj heev thiab feem ntau yog siv alternating tam sim no raws li lawv lub hwj chim mov.
Cov lag luam feem ntau xav tau cov tshuab luam ntawv me me, tshwj xeeb tshaj yog thaum muag khoom sab nraum zoov lossis hauv cov cuab yeej siv tsheb thauj mus los xws li dav hlau thiab tsheb ciav hlau, nqa cov tshuab luam ntawv hnyav los luam cov ntawv txais nyiaj rau cov neeg siv khoom yog qhov tsis ua tau.
Thib ob, laser lossis inkjet tshuab luam ntawv los hloov cov number case cartridges lossis toner feem ntau siv sijhawm thiab siv zog, yog tias nws ncua sijhawm rau cov neeg siv khoom kuaj xyuas, uas tseem tsis txaus siab pom cov lag luam thiab cov neeg siv khoom.
Cov teeb meem no tuaj yeem daws tau los ntawm kev siv cov tshuab luam ntawv thermal thiab cov ntawv thermal es tsis txhob lasers lossis inkjet printers.
Vim tias tus number case twb tau khaws cia rau hauv daim ntawv, cov tshuab luam ntawv thermal tsis tas yuav tsum muaj cov qauv tsim los khaws thiab hloov tus cwj mem thiab tuaj yeem ua me me.
Nws tseem yog roj teeb-powered, ua rau nws zoo tagnrho rau cov lag luam nqa, tshwj xeeb tshaj yog thaum tawm sab nraum zoov lossis hauv kev thauj mus los, luam cov ntawv txais nyiaj rau cov neeg siv khoom.
Vim nws txoj kev tsim kho yooj yim, lub tshuab luam ntawv thermal kuj tseem yooj yim los tswj, thiab cov neeg siv tsis tas yuav txhawj xeeb txog kev hloov cov number case cartridges.Lawv tuaj yeem hloov pauv cov ntawv tshiab ntawm cov ntawv thermal sai li sai tau thaum daim ntawv siv tas.Qhov no ua kom cov neeg siv khoom tsis poob sijhawm ntau dhau.
Tsis tas li ntawd, lub tshuab luam ntawv thermal luam ntawv ceev, tsis tshua muaj suab nrov, haum rau siv hauv khw khw.
Vim tias cov txiaj ntsig zoo no, thermal luam ntawv tsis yog tsuas yog txoj kev nyiam ntawm kev luam ntawv cov ntawv txais nyiaj, tab sis feem ntau siv los luam daim pib, daim ntawv lo thiab faxes.
Cov ntawv thermosensitive kuj muaj qhov tsis zoo, uas yog qhov kev sau ntawv ntawm cov ntawv luam tawm yuav ploj mus dhau sijhawm.
Fading kuj tshwm sim vim yog cov xim tshwj xeeb uas siv hauv cov ntawv thermal.
Raws li peb tau hais ua ntej, cov cryptic dye npog cov ntawv thermal yog xim tsis muaj xim ntawm chav tsev kub, thiab dhau los ua lwm yam qauv nrog cov xim vim muaj tshuaj lom neeg ntawm qhov kub thiab txias.
Txawm li cas los xij, cov qauv tshiab tsis ruaj khov, thiab raws li txoj cai nws rov qab mus rau nws cov qauv tsis muaj xim dhau los.
Piv txwv li, crystalline violet lactone, raws li peb tau hais ua ntej, hloov mus rau hauv cov xim xim nyob rau hauv lub xub ntiag ntawm cov kua qaub, thiab cov xim no tig rov qab mus rau cov xim tsis muaj xim nyob rau hauv lub xub ntiag ntawm ib qho khoom alkaline.
Tom qab khaws daim ntawv txais nyiaj, nws tuaj yeem ntsib ntau yam tshuaj nyob hauv ib puag ncig.Nws kuj tseem tuaj yeem raug tshav ntuj lossis kub kub, uas yuav ua rau cov dyeing ntawm cov ntawv thermal rov qab mus rau nws daim ntawv tsis muaj xim, discoloring daim ntawv txais nyiaj.
Yuav kom daws tau qhov teeb meem no, ntau cov ntawv thermal manufacturers ntxiv ib txheej ntxiv ntawm kev tiv thaiv nyob rau sab saum toj ntawm cov dye txheej kom txo cov dye kev sib cuag nrog lwm yam tshuaj thiab ua rau cov ntaub ntawv luam tawm ntawm thermal ntawv nyob ntev.
Tab sis txoj kev no yuav nce tus nqi ntawm cov ntawv thermal, yog li yuav muaj kev lag luam txuas ntxiv mus siv tsis muaj kev tiv thaiv txheej ntawm cov ntawv thermal zoo tib yam.
Yog tias koj txhawj xeeb tias koj daim ntawv txais nyiaj yuav ploj mus dhau sijhawm, nws yog ib lub tswv yim zoo los luam lossis luam theej koj daim ntawv txais nyiaj.
Nyob rau hauv xyoo tas los no, cov ntawv thermosensitive tau ua rau muaj kev txhawj xeeb ntawm ntau tus neeg siv khoom vim nws muaj bisphenol A.
Bisphenol A yog cov tshuaj acidic, yog li nws yog siv rau hauv cov ntawv thermosensitive uas nws hnov mob nrog cov xim tsaus nti ntawm qhov kub thiab txias los tsim cov xim.
Tsis tas li ntawd, bisphenol A feem ntau yog siv los ua A raw khoom los ua tej yam yas los yog coatings.
Yog li txoj hauv kev tseem ceeb uas BPA nkag mus rau hauv lub cev yog thaum koj muab cov zaub mov tso rau hauv cov thawv no, cov khoom me me ntawm BPA nkag mus rau hauv lub cev nrog rau cov zaub mov.
Tab sis nyob rau hauv xyoo tas los no, cov kev tshawb fawb pom tau hais tias raug rau cov ntawv luam tawm ntawm daim ntawv kub-sensitive tej zaum yuav ua rau BPA nkag mus rau hauv lub cev.
Ib txoj kev tshawb fawb tsis ntev los no, piv txwv li, pom tias BPA qib hauv cov zis tau nce ntxiv tom qab lub sijhawm ntev ntawm cov ntawv kub-rhiab heev.
Vim hais tias bisphenol A cov qauv tshuaj zoo ib yam li estradiol, lub ntsiab estrogen tsim los ntawm lub cev, muaj kev txhawj xeeb tias nws yuav cuam tshuam rau cov endocrine secretion thiab ua rau muaj kev pheej hmoo ntawm ntau yam kab mob.
Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum tau taw qhia tias qhov ntau ntawm BPA hauv lub cev los ntawm cov khoom noj thiab cov ntawv thermal tsawg heev, yog li nws nyuaj rau kev paub meej txog kev noj qab haus huv ntawm BPA hauv tib neeg.
Txawm li cas los xij, thaum BPA tsis tau txwv tam sim no hauv kev tsim cov ntawv thermal, ntau lub tuam txhab tau pib siv lwm cov kua qaub hloov.
Yog tias koj txhawj xeeb txog Ib qho me me ntawm BPA nkag mus rau koj lub cev los ntawm kev sib cuag nrog cov ntawv txais nyiaj, Kev ceev faj ntau dua yog khaws cov ntawv txais nyiaj nyob rau hauv kev sib cais kom sai li sai tau yam tsis txhob kov lawv, thiab ntxuav koj txhais tes tom qab kov cov ntawv txais nyiaj.
Tau kawg, hloov daim ntawv txais nyiaj nrog cov khoom siv hluav taws xob yuav ua rau muaj kev noj qab haus huv thiab zoo ib puag ncig.
