Chii chinonzi Printing Inks?

Sezvatinoziva tese,inkisanganiswa yunifomu yemitumbi yemavara (yakadai se pigment, dyes, nezvimwewo), mabhandi, kuzadza (kuzadza) zvinhu, zvimwe zvinhu, nezvimwewo, zvinogona kudhindwa nekuomeswa pamutumbi wakadhindwa.Iyo inonamira slurry ine ruvara uye imwe dhigirii yekuyerera.Naizvozvo, ruvara (hue), muviri (ukobvu, kuyerera uye zvimwe rheological properties) uye kuomesa kuita ndiyo ingi yeatatu anonyanya kukosha kuita.Iwo marudzi mazhinji, zvimiro zvemuviri hazvina kufanana, mamwe akakora kwazvo, anonamira zvakanyanya, nepo mamwe ari matete.Mamwe anoshandisa mafuta emuriwo semabhandi, uye mamwe anoshandiswa semabhainda ane resin nezvinonyungudutsa kana mvura.Izvi zvinoenderana nechinhu chakadhindwa chinova substrate, nzira yekudhinda, mhando yepureti yekudhinda uye nzira yekuomesa yekuona.

Function

Inki imhando yekunamira kwetsvina ine kumwe kunyungudika, viscosity, kukosha kwakashata, thixotropy, fluidity, kuoma uye zvichingodaro zvese zvinotarisa kuita kweinki.

Viscosity

Icho chinhu chinodzivirira kuyerera kwechinhu chemvura, chiyero chekudyidzana pakati pemamorekuru emvura anotadzisa kufamba kwehukama pakati pemamorekuru ayo, ndiko kuti, kuramba kwekuyerera kwemvura.

Goho Kukosha

Ndiko kushomeka kwekufamba kushushikana kunodiwa kutungamira mvura kuti itange kuyerera.

Fluidity

Zvinoreva ingi musimba rayo regiravhiti, richayerera semvura, neingi viscosity, goho ukoshi uye thixotropy chisarudzo, panguva imwe chete kudhinda ingi uye tembiricha zvakare zvakabatana.

Composition

Pigment ndiko kuumbwa kwakasimba kweinki, ink color material, inowanzosanyungudika mumvura pigment.Ink color saturation, coloring kudhinda inki simba, pachena uye kumwe kuita uye pigment kuita kune hukama hwepedyo.Iyo binder inhengo yemvura yeinki, uye pigment ndiyo inotakura.Muchiito chekudhinda, binder inotakura pigment particles, kubva pakudhinda inki hafu kuburikidza neinki roller, kudhinda ndiro, inokanda kune substrate kuti iite inki firimu, yakagadziriswa, yakaoma uye yakanamatira kune substrate.Kubwinya, kuoma, simba remagetsi uye zvimwe zvinhu zvemufirimu weinki zvine chokuita nekushanda kwebhainda.

Saizvozvo,ingi dzekudhindainogona kushandiswa kakawanda.Zvichakadaro, tinofanira kungwarira kushandiswa kwayo.
