Isu tinoona mumugwagwa iwo mavara akapfuma, echokwadi makuru-mafomati ads, ari mafoto muchina kudhinda.Uye maererano nemashandisirwo akasiyana ekushandisa isu tinoshandisa inki haina kufanana, nhasi xiaobian kukupa tsananguro iri nyore yemuchina wepikicha neingi misiyano mishoma:
Muchina wepikicha unonyanya kushandiswa kune ane mafuta inki pigment dilution muoiri, senge mineral oil, mafuta emuriwo, inki pane yekudhinda svikiro nekupinza kwemafuta uye evaporation pigment inonamirwa pakati; Mvura-based inki imvura senzira yekuparadzira, inki pane inodhinda svikiro kuburikidza nekupinzwa uye evaporation yemvura pigment yakanamirwa kune yepakati pemvura.
Photo indasitiri ingi maererano nekushandiswa kusiyanisa, inogona kukamurwa kuva marudzi maviri:Imwe ingi inogadzirwa nemvura, iyo inonyanya kuumbwa nemvura uye zvinonyunguduka mumvura.
Imwe yacho, ingi ine mafuta, insoluble solvent sechinhu chikuru cheiyo yakanyungudika ruvara base.
Zvinoenderana nekunyungudika kwe solvent, inogona zvakare kukamurwa mumhando nhatu:
Chekutanga, dhayi ingi: iri dhayi based inki, akawanda emukati mafoto muchina ari kushandiswa;
Yechipiri, pigment inki: inobva pane pigment inki, inoshandiswa kumashini ekunze ekudhinda.
Yetatu, isina kusimba inki yekunyungudutsa: pakati pezviviri, inoshandiswa kumashini ekunze emifananidzo.
Kunyanya kutarisisa kunofanirwa kubhadharwa kune chokwadi chekuti idzi ingi nhatu hadzigone kushandiswa pamwechete. Mvura-based muchina unogona chete kushandisa mvura-based inki,uye muchina wakavakirwa nemafuta unogona kushandisa inki isina simba yekunyungudutsa uye inki yekunyungudutsa. Sezvo inki cartridge, pombi uye nozzle yemuchina wemvura-wakavakirwa muchina uye mafuta-based muchina zvakasiyana kana muchina waiswa, iyo inki haigone kushandiswa zvisina tsarukano.
Izvo zvinokanganisa kunaka kweinki zvakanyanya zvine zvishanu zvinhu: dispersant, conductivity, PH kukosha, kushushikana kwepasi, viscosity.
1) dispersant:is a surfactant, basa rayo ndere kuvandudza hunhu hweiyo ingi pamusoro, kuwedzera kuwirirana kweinki uye chipanje, mwando. Saka kazhinji kuburikidza nesiponji kuchengetedza, conduction yeinki ine dispersants.
2) Electrical conductivity:kukosha uku kunoshandiswa kuratidza munyu waro.Ingi dzemhando dziri nani hadzifanire kunge dzine munyu unopfuura 0.5% kudzivirira crystallization pamuromo.Ingi yemafuta zvichienderana nekukura kwepigment, sarudza kushandisa iyo nozzle, hombe yekupfapfaidza muchina 15PL, 35PL inoenderana nehukuru hwechikamu kuti uone kurongeka kwemushini weinkjet, izvi zvakakosha.
3) PH kukosha:inoreva mvura PH, iyo yakanyanya acidic mhinduro, iyo yakaderera iyo PH kukosha, pane zvinopesana, iyo yakawanda alkaline mhinduro, yakakwirira iyo PH kukosha.Kuitira kudzivirira inki corrosion nozzle, PH kukosha kunofanira kazhinji kuva pakati pe7-12.
4) kushushikana kwepamusoro:inogona kukanganisa kuumbwa kweingi madonhwe, yakanaka yemhando inki yakaderera viscosity, yakakwira kumusoro tension.
5) viscosity:ndiko kuti, kushorwa kwekuyerera kwemvura, viscosity yeinki yakakura kwazvo, ichaita kuti kudhindwa kweinki kugovera.
kukanganisa;Viscosity idiki kwazvo, inoburitsa inki inoyerera mukudhinda. Ingi pane yakajairika tembiricha yemukamuri, kazhinji inogona kuchengetwa kwemwedzi 3-6, nguva yakarebesa kana kunaya, uye inokanganisa kushandiswa kana plug, inki yekuchengetedza zvinodiwa yakavharwa, kudzivirira zuva rakananga, tembiricha haifanire kunge yakanyanya kana kuderera.
