Kodi Printing Inks ndi chiyani?

Monga tonse tikudziwa,inkindi chisakanizo cha yunifolomu ya matupi amitundu (monga pigments, dyes, etc.), zomangira, kudzaza (kudzaza) zipangizo, zipangizo zowonjezera, ndi zina, zomwe zingathe kusindikizidwa ndi zouma pa thupi losindikizidwa.Ndi slurry zomatira ndi mtundu ndi ena otaya digiri.Chifukwa chake, mtundu (hue), thupi (makulidwe, kuyenda ndi zinthu zina za rheological) ndi kuyanika ntchito ndi inki yazinthu zitatu zofunika kwambiri.Zili zamitundumitundu, zakuthupi sizifanana, zina ndi zokhuthala kwambiri, zomata kwambiri, pomwe zina ndizoonda kwambiri.Ena amagwiritsa ntchito mafuta a masamba monga zomangira, ndipo ena amagwiritsidwa ntchito ngati zomangira ndi utomoni ndi zosungunulira kapena madzi.Izi zimachokera ku chinthu chosindikizidwa chomwe ndi gawo lapansi, njira yosindikizira, mtundu wa mbale yosindikizira ndi njira yowumitsa kuti mudziwe.

Ntchito

Inki ndi mtundu wa slurry zomatira ndi ena fluidity, mamasukidwe akayendedwe, zoipa mtengo, thixotropy, fluidity, dryness ndi zina zotero zonse kudziwa ntchito ya inki.

Viscosity

Ndi katundu amene amalepheretsa kutuluka kwa zinthu zamadzimadzi, muyeso wa mgwirizano pakati pa mamolekyu amadzimadzi omwe amalepheretsa kuyenda kwachibale pakati pa mamolekyu ake, ndiko kuti, kukana kwa madzi othamanga.

Mtengo Wokolola

Ndiko kupsinjika kocheperako komwe kumafunikira kutsogolera madzi kuti ayambe kuyenda.

Kuchuluka kwa madzi

Amatanthauza inki mu mphamvu yokoka, idzayenda ngati madzi, ndi inki mamasukidwe akayendedwe, zokolola mtengo ndi thixotropy chisankho, pa nthawi yomweyo kusindikiza inki ndi kutentha nawonso ogwirizana.

Kupanga

Pigment ndi mtundu wolimba wa inki, zinthu zamtundu wa inki, nthawi zambiri sizisungunuka mu pigment yamadzi.Machulukidwe amtundu wa inki, mphamvu ya inki yosindikizira, kuwonekera ndi magwiridwe antchito ena komanso magwiridwe antchito a pigment ali ndi ubale wapamtima.Chomangira ndi chigawo chamadzimadzi cha inki, ndipo pigment ndi chonyamulira.Posindikiza, binder imanyamula tinthu tating'onoting'ono ta pigment, kuchokera ku makina osindikizira a inki theka kupyolera mu chopukusira cha inki, mbale yosindikizira, kuponyera ku gawo lapansi kuti apange filimu ya inki, yokhazikika, yowuma ndi yomatira ku gawo lapansi.Kuwala, kuuma, mphamvu zamakina ndi zina za filimu ya inki zimagwirizana ndi ntchito ya binder.

Pamenepo,inki zosindikiziraangagwiritsidwe ntchito nthawi zambiri.Pakali pano, tiyenera kulabadira kagwiritsidwe ntchito kake.
