Feem ntau peb tham txog kev luam ntawv, yog los ntawm ib txoj hauv kev tshwj xeeb los hloov cov kua mem mus rau ib cheeb tsam ntawm daim ntawv, yog li peb xav tau cov lus lossis cov duab kos.
Cov tshuaj uas ua rau daim ntawv tsis nqus lub teeb ntawm txhua xim ntau, yog li thaum lub teeb ci ntsa iab los ntawm saum npoo ntawm daim ntawv thiab nkag mus rau hauv peb lub qhov muag, peb pom nws dawb.
Cov xim lossis cov xim zas hauv cov kua mem nqus qee lossis tag nrho cov teeb pom kev, yog li thaum cov kua mem siv rau ntawm daim ntawv, qhov chaw ntawm daim ntawv dawb yuav muaj xim.
Cov hom tshuab luam ntawv tseem ceeb uas peb siv hauv tsev lossis hauv chaw ua haujlwm yog cov tshuab luam ntawv inkjet thiab cov tshuab luam ntawv laser.
Tsis zoo li cov tshuab luam ntawv inkjet, uas tsuag cov kua me me rau ntawm daim ntawv, cov tshuab luam ntawv laser nyiam cov toners rau ntawm lub nruas me me thiab xa lawv mus rau ntawm daim ntawv los ntawm kev rub hluav taws xob.
Txawm li cas los xij, daim ntawv txais nyiaj tsis tau luam tawm li no. Nws tau luam tawm rau ntawm ib hom ntawv tshwj xeeb, hu ua ntawv thermal.
Piv nrog rau daim ntawv ib txwm muaj, daim ntawv thermosensitive muaj ib txheej nyias nyias ntawm nws qhov chaw, uas muaj qee cov tshuaj tshwj xeeb hu ua cryptic dyes.
Cov xim zas dig muag nws tus kheej tsis muaj xim, yog li daim ntawv thermal tshiab yuav zoo li dawb li daim ntawv ib txwm muaj.
Txawm li cas los xij, thaum ua tau raws li qhov xwm txheej zoo, lawv ua rau muaj kev sib xyaw ua ke, thiab cov khoom tshiab nqus tau lub teeb pom kev, thiab peb pom xim.
Muaj ntau yam tshuaj, xws li crystalline violet lactone, txawm hais tias tsis muaj xim ntuj, tab sis hloov xim av thaum muaj kua qaub.
Yog li ntawd, thaum peb luam tawm ntawm daim ntawv thermosensitive, cov kua mem tsis khaws cia rau hauv lub tshuab luam ntawv, nws twb nyob ntawm daim ntawv lawm.

Daim duab
Daim Duab 1 Crystalline violet lactone yuav hloov ntawm tsis muaj xim mus rau xim ntshav thaum muaj cov tshuaj acidic, thiab yuav tsis muaj xim dua thaum muaj cov tshuaj alkaline.

Tab sis cov xim cryptic xws li crystallactone, uas yooj yim reacts nrog acids, yog khov kho ntawm chav tsev kub, thiab cov molecules raug xauv rau hauv qhov chaw.
Yog tias koj tab tom cuam tshuam nrog cov kua qaub uas kuj yog cov khoom khov, koj tuaj yeem nyob ua ke ntev heev ntawm chav tsev kub, txawm tias koj nyob ze.
Yog li ntawd, peb tuaj yeem siv cov xim tsaus no, uas khov kho ntawm chav tsev kub, thiab zom cov khoom khov kho ntawm lwm cov tshuaj acidic ua hmoov zoo, sib tov thiab pleev rau ntawm qhov chaw ntawm daim ntawv, thiab peb tau txais daim ntawv thermal.
Thaum sov li chav tsev, daim ntawv thermal zoo li daim ntawv ib txwm;
Thaum qhov kub nce siab, cov xim tsaus nti thiab cov kua qaub yaj ua kua, thiab cov molecule txav mus los dawb sib ntsib thiab teb tam sim ntawd, yog li daim ntawv dawb sai sai qhia xim.
Qhov no yog qhov uas daim ntawv thermosensitive tau nws lub npe - nws tsuas yog kub txaus kom hloov xim.
Nrog daim ntawv thermal, yog tias koj xav luam cov ntawv lossis cov duab kos rau ntawm nws qhov chaw, koj kuj xav tau lub tshuab luam ntawv tshwj xeeb, uas yog lub tshuab luam ntawv thermal.
Yog koj puas tau rhuav lub tshuab luam ntawv thermal, koj yuav pom tias nws sab hauv yooj yim heev: tsis muaj lub thawv number case. 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 los ntawm cov yob.
Thaum muab ib daim ntawv thermal dov rau hauv lub tshuab luam ntawv, nws raug thawb mus tom ntej los ntawm lub roller thiab kov lub taub hau luam ntawv.
Muaj ntau lub ntsiab lus me me ntawm lub taub hau luam ntawv uas ua rau thaj chaw tshwj xeeb ntawm daim ntawv sov raws li cov lus lossis cov duab kos uas peb xav luam tawm.
Thaum lub sijhawm sib cuag ntawm daim ntawv thermal thiab lub taub hau luam ntawv, qhov kub siab uas tsim los ntawm lub taub hau luam ntawv ua rau cov xim thiab cov kua qaub ntawm qhov chaw ntawm daim ntawv thermal yaj ua ke ua kua thiab ua rau muaj kev sib xyaw ua ke, yog li ntawd qhov chaw ntawm daim ntawv tshwm sim cov cim lossis cov duab kos.
Daim ntawv txais nyiaj yuav khoom raug luam tawm los ntawm lub roller.
Daim duab
Daim Duab 2 Lub hauv paus ntsiab lus ua haujlwm ntawm lub tshuab luam ntawv thermal: daim ntawv thermal txav mus tom ntej los ntawm lub nruas. Thaum nws kov lub taub hau luam ntawv, cua sov tsim los ntawm lub taub hau luam ntawv yaj cov xim thiab kua qaub rau ntawm qhov chaw ntawm daim ntawv thermal, thiab ob qho tshuaj lom neeg ua rau muaj xim.

Vim li cas cov lag luam thiaj siv daim ntawv thermal thiab cov tshuab luam ntawv thermal los luam cov ntawv txais nyiaj yuav khoom, es tsis siv cov tshuab luam ntawv laser lossis inkjet uas paub zoo dua?
Ua ntej, cov tshuab luam ntawv laser lossis inkjet xav tau cov khoom siv nyuaj los xa cov kua mem lossis toner los ntawm lub tshuab luam ntawv mus rau daim ntawv. Ob lub tshuab luam ntawv no loj thiab feem ntau siv hluav taws xob hloov pauv ua lawv lub zog.
Cov lag luam feem ntau xav tau cov tshuab luam ntawv me me, tshwj xeeb tshaj yog thaum muag khoom sab nraum zoov lossis ntawm cov cuab yeej thauj mus los xws li dav hlau thiab tsheb ciav hlau, kev nqa cov tshuab luam ntawv hnyav los luam cov ntawv txais nyiaj rau cov neeg siv khoom yeej tsis yooj yim.
Qhov thib ob, lub tshuab luam ntawv laser lossis inkjet los hloov cov cartridges lossis toner feem ntau siv sijhawm thiab ua haujlwm ntau, yog tias nws ncua sijhawm rau cov neeg siv khoom them nqi, uas kuj tsis xav 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 daim ntawv thermal es tsis txhob siv lasers lossis inkjet printers.
Vim tias cov kua mem twb tau khaws cia ua ntej rau ntawm daim ntawv, cov tshuab luam ntawv thermal tsis xav tau cov qauv nyuaj los khaws thiab xa cov kua mem thiab tuaj yeem me heev.
Nws kuj siv roj teeb, ua rau nws zoo tagnrho rau cov lag luam nqa, tshwj xeeb tshaj yog thaum sab nraum zoov lossis thaum thauj mus los, los luam cov ntawv txais nyiaj rau cov neeg siv khoom.
Vim nws yooj yim siv, lub tshuab luam ntawv thermal kuj yooj yim rau kev saib xyuas, thiab cov neeg siv tsis tas yuav txhawj txog kev hloov cov cartridges. Lawv tuaj yeem hloov daim ntawv thermal tshiab sai li sai tau thaum daim ntawv siv tag. Qhov no ua kom cov neeg siv khoom tsis plam sijhawm ntau dhau.
Tsis tas li ntawd, lub tshuab luam ntawv thermal luam ntawv ceev, suab nrov tsawg, zoo heev rau kev siv hauv khw loj.
Vim yog cov txiaj ntsig no, kev luam ntawv thermal tsis yog tsuas yog txoj hauv kev nyiam tshaj plaws ntawm kev luam cov ntawv txais nyiaj yuav khoom xwb, tab sis kuj tseem siv los luam daim pib, daim ntawv lo thiab txawm tias cov faxes.
Daim ntawv thermosensitive kuj muaj qhov tsis zoo loj, uas yog tias cov ntawv sau rau ntawm daim ntawv luam tawm yuav ploj mus raws sijhawm.
Kev ploj zuj zus kuj tshwm sim vim yog cov xim tshwj xeeb siv hauv daim ntawv thermal.
Raws li peb tau hais ua ntej lawm, cov xim cryptic uas npog daim ntawv thermal tsis muaj xim ntawm chav tsev kub, thiab dhau los ua lwm cov qauv nrog xim vim yog cov tshuaj lom neeg ntawm qhov kub siab.
Txawm li cas los xij, cov qauv tshiab tsis ruaj khov, thiab nyob rau hauv cov xwm txheej zoo nws rov qab mus rau nws cov qauv tsis muaj xim yav dhau los.
Piv txwv li, crystalline violet lactone, raws li peb tau hais ua ntej, hloov mus ua cov qauv xim nyob rau hauv qhov muaj cov tshuaj acid, thiab cov qauv xim no hloov rov qab mus rau cov qauv tsis muaj xim nyob rau hauv qhov muaj cov tshuaj alkaline.
Tom qab daim ntawv txais nyiaj uas luam tawm lawm khaws cia, nws yuav kov tau ntau yam tshuaj lom neeg hauv ib puag ncig. Nws kuj tseem yuav raug tshav ntuj lossis kub heev, uas yuav ua rau cov xim ntawm daim ntawv thermal rov qab mus rau nws daim ntawv tsis muaj xim, ua rau daim ntawv txais nyiaj tsis muaj xim.
Yuav kom daws tau qhov teeb meem no, ntau lub tuam txhab tsim ntawv thermal ntxiv ib txheej tiv thaiv ntxiv rau saum txheej xim kom txo qhov kev sib cuag ntawm cov xim nrog lwm cov tshuaj lom neeg thiab ua rau cov ntaub ntawv luam tawm ntawm ntawv thermal kav ntev dua.
Tab sis txoj kev no yuav ua rau tus nqi ntawm daim ntawv thermal nce ntxiv, yog li yuav muaj cov lag luam txuas ntxiv siv tsis muaj txheej tiv thaiv ntawm daim ntawv thermal ib txwm muaj.
Yog koj txhawj tias koj daim ntawv txais nyiaj yuav ploj mus raws sijhawm, nws yog ib lub tswv yim zoo los theej lossis luam theej koj daim ntawv txais nyiaj.
Nyob rau xyoo tas los no, daim ntawv thermosensitive tau ua rau muaj kev txhawj xeeb ntawm ntau tus neeg siv khoom vim nws muaj bisphenol A.
Bisphenol A yog ib yam khoom uas muaj kua qaub, yog li nws siv rau hauv daim ntawv thermosensitive qhov twg nws reacts nrog cov xim tsaus ntawm qhov kub siab kom tsim cov xim.
Ntxiv rau, bisphenol A feem ntau siv los ua cov khoom siv raw los ua qee yam yas lossis txheej.
Yog li ntawd, txoj hauv kev tseem ceeb uas BPA nkag mus rau hauv lub cev yog thaum koj muab zaub mov tso rau hauv cov thawv no, me me ntawm BPA nkag mus rau hauv lub cev nrog rau cov zaub mov.
Tab sis nyob rau xyoo tas los no, kev tshawb fawb tau qhia tias kev raug cov ntawv sau rau ntawm daim ntawv uas rhiab rau cua sov kuj tseem 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 cov qib hauv cov zis nce ntxiv tom qab raug rau daim ntawv kub-rhiab heev ntev.
Vim tias bisphenol A cov qauv tshuaj lom neeg zoo ib yam li estradiol, cov tshuaj estrogen tseem ceeb uas lub cev tsim tawm, muaj kev txhawj xeeb tias nws yuav cuam tshuam rau kev tso pa tawm ntawm endocrine 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 taw qhia tias qhov concentration ntawm BPA hauv lub cev los ntawm cov khoom noj thiab daim ntawv thermal yog qis heev, yog li nws nyuaj rau lees paub cov teebmeem kev noj qab haus huv ntawm BPA rau tib neeg.
Txawm li cas los xij, thaum BPA tsis raug txwv tam sim no hauv kev tsim cov ntawv thermal, ntau lub tuam txhab tsim khoom tau pib siv lwm cov kua qaub hloov chaw.
Yog tias koj txhawj xeeb txog BPA me me nkag mus rau hauv koj lub cev los ntawm kev sib cuag nrog cov ntawv txais nyiaj, ib qho kev ceev faj zoo dua yog khaws cov ntawv txais nyiaj cais tawm sai li sai tau yam tsis txhob kov lawv, thiab ntxuav koj txhais tes tom qab kov cov ntawv txais nyiaj.
Tau kawg, kev hloov daim ntawv txais nyiaj nrog cov ntawv hluav taws xob yuav zoo rau kev noj qab haus huv thiab zoo rau ib puag ncig.
