Isu tinowanzo kutaura nezve kudhinda, kuburikidza neimwe nzira yekuendesa inki kune imwe nzvimbo yepepa, kuitira kuti isu tide kuwana mazwi kana magirafu.
Makemikari anoumba bepa haatore chiedza cheruvara ripi zvaro zvakanyanya, saka kana chiedza chikabuda pamusoro pepepa uye mumaziso edu, tinozviona sechena.
Iyo pigment kana dhayi muinki inotora chimwe kana chese chechiedza chinooneka, kuitira kuti kana ingi ikaiswa pamusoro pebepa, pamusoro pebepa jena rinova neruvara.
Mhando huru dzemaprinta atinoshandisa kumba kana muhofisi inkjet printer uye laser printers.
Kusiyana nemaprinta einkjet, anopfapfaidza tudonhwe twudiki tweingi pabepa, maprinda emalaser anokwevera matonho kudhiramu rakareruka oaendesa pabepa nenzira yemagetsi.
Zvisinei, risiti haina kudhindwa nenzira iyi. Inodhindwa pamhando yepepa, inonzi thermal paper.
Kana ichienzaniswa nebepa rakajairika, bepa rinopisa rinopisa rine jira rakatetepa pamusoro paro, rine mamwe makemikoro anonzi cryptic dyes.
Dhayi yebofu pachayo haina ruvara, saka bepa richangotengwa rinopisa rinotaridzika sechena semapepa akajairika.
Zvisinei, kana mamiriro ezvinhu akakodzera asangana, anoita nekemikari, uye zvinhu zvitsva zvinotora chiedza chinooneka, uye tinoona ruvara.
Zvinhu zvakawanda, zvakadai secrystalline violet lactone, kunyange zvazvo zvisina ruvara, zvinoshandura ruvara rwepepuru pamberi peasidhi.
Ndiko kuti, kana tikadhinda pabepa re thermosensitive, inki haina kuchengetwa muprinta, yatova papepa.

Mufananidzo
Fig. 1 Crystalline violet lactone inoshanduka kubva pakusava neruvara kuenda kupepuru kana paine zvinhu zvine acidic, uye inozova isina ruvara zvakare kana paine alkaline zvinhu.

Asi cryptic dhayi dzakadai secrystallactone, iyo inopindirana nyore neasidhi, yakasimba pakupisa kwekamuri, uye mamorekuru anovharirwa panzvimbo.
Kana uri kutarisana neasidhi iyo yakasimba zvakare, unogona kugara pamwe chete kwenguva yakareba mukamuri yekushisa, kunyange iwe uri pedyo.
Nokudaro, tinogona kutora dhayi idzi dzakasvibirira, dzakasimba pakupisa kwekamuri, uye kukuya kusimba kwechimwe chinhu chine acidic muupfu hwakatsetseka, kuisanganisa uye kuizora pamusoro pepepa, uye tinowana pepa rinopisa.
Patembiricha yemumba, bepa rinopisa rinotaridzika sebepa renguva dzose;
Panongokwira kutonhora, dhayi yakasviba uye asidhi inonyunguduka ikava mvura, uye mamorekuru anofamba akasununguka anosangana uye anoita pakarepo, saka bepa jena rinokurumidza kuratidza ruvara.
Apa ndipo panowana bepa re thermosensitive zita raro -- rinongopisa chete kuti richinje ruvara.
Nebepa rinopisa, kana iwe uchida kudhinda zvinyorwa kana magirafu pamusoro payo, iwe unodawo yakakosha printa, iyo inodhinda inopisa.
Kana ukambopaza dhinda rinopisa, uchaona kuti mukati maro iri nyore: hapana ingi katuriji. Zvikamu zvikuru idhiramu uye musoro wekudhinda.
Iro bepa rinopisa rinoshandiswa kudhinda risiti rinowanzoitwa mumipumburu.
Kana roll yebepa rinopisa ichiiswa muprinta, inofambiswa mberi neroller uye inosangana nemusoro wekudhinda.
Pane zvakawanda zvidiki semiconductor zvinhu zviri pamusoro pemusoro wekudhinda izvo zvinopisa nzvimbo dzebepa zvinoenderana nemashoko kana magirafu atinoda kudhinda.
Panguva yekubatana pakati pebepa rinopisa uye musoro wekudhinda, tembiricha yakakwira inogadzirwa nemusoro wekudhinda inoita kuti dhayi neasidhi iri pamusoro pebepa rinopisa rinyunguduke pamwechete kuita mvura uye rinoita makemikari, saka iyo yepepa inotaridzika mavara kana magirafu. .
Yakadonha neroller, risiti yekutenga inodhindwa.
Mufananidzo
Mufananidzo 2 Nheyo yekushanda yeprinta yekupisa: bepa rinopisa rinoenda mberi richifambiswa nedhiramu. Kana zvasvika pakusangana nemusoro wekudhinda, kupisa kunoitwa nemusoro weprint inonyungudutsa dhayi uye asidhi pamusoro pepepa rinopisa, uye maviri anoita kemikari kuti abudise ruvara.

Sei mabhizinesi achishandisa bepa rinopisa uye maprinta anopisa kudhinda marisiti ekutenga, pane anojairika laser kana inkjet printer?
Chekutanga, laser kana inkjet printa inoda michina yakaoma kutamisa inki kana toner kubva kuprinta kuenda kune bepa. Ose maprinta ane hombe uye anowanzo shandisa alternating current semagetsi ekupa.
Mabhizinesi anowanzoda maprinta madiki, kunyanya kana achitengesa zvinhu kunze kana pamidziyo yekufambisa yakaita sendege nezvitima, kutakura maprinta anorema kudhinda marisiti evatengi zviri pachena kuti hazvishande.
Chechipiri, laser kana inkjet printer kutsiva inki cartridges kana toner inowanzotora nguva uye ine basa, kana ikanonotsa mutengi kubuda, izvo zvakare zvakanyanya kuzeza kuona bhizinesi nevatengi.
Matambudziko aya anogona kugadziriswa nekushandisa maprinta anopisa uye bepa rinopisa pachinzvimbo chemalaser kana inkjet printer.
Nekuti ingi yakatochengetwa kare pabepa, maprinta anopisa haadi zvimiro zvakaoma kuchengeta uye kutamisa ingi uye anogona kunge ari madiki.
Iyo zvakare ine bhatiri-powered, zvichiita kuti ive yakanaka kuti mabhizinesi atakure, kunyanya kana ari panze kana pazvifambiso, kudhinda marisiti evatengi.
Nekuda kwekuvakwa kwayo kwakapfava, thermal printer zvakare iri nyore kuchengetedza, uye vashandisi havafanirwe kunetseka nezve kutsiva ingi cartridges. Vanogona kungotsiva mupumburu mutsva wepepa rinopisa kana bepa rashandiswa. Izvi zvinoita kuti vatengi vasarasikirwa nenguva yakawandisa.
Mukuwedzera, iyo inopisa printer kudhinda kumhanya, yakaderera ruzha, yakanyatsokodzera kushandiswa muchitoro chekutenga.
Nekuda kweaya mabhenefiti, kudhinda kwemafuta haisi iyo chete nzira yakasarudzika yekudhinda maresiti ekutenga, asi inowanzoshandiswa kudhinda matikiti, mavara uye kunyange fax.
Thermosensitive bepa zvakare rine chikuru drawback, ndiko kuti kunyora pagwaro rakadhindwa kuchapera nekufamba kwenguva.
Kusvava kunoitikawo nekuda kwedhayi dzakasiyana dzinoshandiswa mumapepa anopisa.
Sezvatakambotaura, iyo cryptic dhayi yakavhara bepa rinopisa haina ruvara pakupisa kwekamuri, uye inova chimwe chimiro chine ruvara nekuda kwekuita kwemakemikari pakupisa kwakanyanya.
Zvisinei, chimiro chitsva hachina kugadzikana, uye pasi pemamiriro ezvinhu akakodzera chinodzokera kune chimiro chayo chekare chisina ruvara.
Semuenzaniso, crystalline violet lactone, sezvatakambotaura, inoshanduka kuita chimiro chemavara pamberi pechinhu cheasidhi, uye chimiro chemavara ichi chinodzokera kune chimiro chisina ruvara kana paine chinhu chealkaline.
Mushure mekunge risiti yakadhindwa yachengetwa, inogona kusangana nemhando dzakasiyana dzemakemikari munharaunda. Inogonawo kupiswa nezuva kana kuti tembiricha yakakwira, izvo zvingaita kuti dhayi iri pabepa rinopisa idzokere kuchimiro chayo chisina ruvara, zvichiita kuti risiti yacho ishanduke.
Kugadzirisa dambudziko iri, vagadziri vemapepa akawanda anopisa vanowedzera imwe yekudzivirira pamusoro pedhayi kuti dhayi ibatane nemamwe makemikari uye kuita kuti magwaro akadhindwa pabepa rinopisa agare kwenguva refu.
Asi iyi nzira ichawedzera mutengo webepa rinopisa, saka kuchave nemabhizinesi ekuenderera mberi nekushandisa pasina inodzivirira pepa rakajairwa rinopisa.
Kana uchityira kuti risiti yako ichapera nekufamba kwenguva, ipfungwa yakanaka kukopa kana kuongorora risiti yako.
Mumakore achangopfuura, bepa rethermosensitive rakakonzera kushushikana pakati pevatengi vazhinji nekuti rine bisphenol A.
Bisphenol A chinhu chine acidic, saka chinoshandiswa mubepa rethermosensitive painopindirana nedhayi dzakasviba pakudziya kwepamusoro kuti ibudise ruvara.
Pamusoro pezvo, bisphenol A inonyanya kushandiswa seA raw material kugadzira mamwe mapurasitiki kana machira.
Saka nzira huru iyo BPA inopinda nayo mumuviri ndepaunoisa chikafu mumidziyo iyi, shoma shoma dzeBPA dzinopinda mumuviri pamwe chete nechikafu.
Asi mumakore achangopfuura, zvidzidzo zvakaratidza kuti kuratidzwa kune zvinyorwa zvakadhindwa pabepa rinonzwa kupisa kunogonawo kukonzera BPA kupinda mumuviri.
Imwe ongororo ichangoburwa, semuenzaniso, yakawana kuti BPA mazinga muweti akawedzera mushure mekuratidzwa kwenguva refu kune bepa rinonzwa kupisa.
Nemhaka yekuti bisphenol A's chemical structure yakafanana neestradiol, iyo estrogen huru inogadzirwa nemuviri, pane zvinonetsa kuti inogona kupindira neyakajairwa endocrine secretion uye kuwedzera njodzi yeChiverengero chezvirwere.
Zvisinei, zvakakosha kuratidza kuti kuwedzera kweBPA mumuviri kuburikidza nezvokudya uye mapepa ekupisa kwakaderera zvikuru, saka zvakaoma kusimbisa hutano hwehutano hweBPA muvanhu.
Zvisinei, nepo BPA isati yarambidzwa mukugadzirwa kwepepa rinopisa, vagadziri vakawanda vakatanga kushandisa mamwe maasidhi panzvimbo.
Kana iwe uchinetseka nezveChishoma cheBPA ichipinda muhurongwa hwako kubva pakubata nemarisiti, Imwe nzira yekuzvidzivirira ndeyekuchengetedza marisiti ari ega nekukurumidza pasina kuabata, uye kugeza maoko ako mushure mekubata marisiti.
Chokwadi, kutsiva mapepa emarisiti neamagetsi kungave kune hutano uye kunoenderana nemhoteredzo.
