Offset Tshuab Luam Ntawv Ink

Xim: Qhov no yog cov xim sib xyaw uas txiav txim siab tus kua txob, thiab lwm yam tshuaj pleev xim rau cov pa roj carbon monoxide, thiab lwm yam tshuaj lom neeg pigentures, yog siv rau cov inks xim.

Lub tsheb: Nws yog ib feem ntawm cov kua uas tuav thiab thauj cov pegment hais. Cov tsheb uas muaj xws li cov roj zoo li cov roj suaya lossis roj linseed, thiab cov khoom cua xws li cov khoom siv phenolic xws li Phenolic Resins.

MRIFIERS: Cov no yog ntxiv rau tswj tus mem kua ceev, hnov ​​ntxhiab tsw, tsis kam rau fading, thiab lwm yam khoom. Piv txwv li, kev ua kom qhuav ziab kom qhuav, thiab cov teeb meem tiv thaiv cov teeb meem xws li cov teeb meem tsis tso.

Kev sib faib

Los ntawm luam ntawv Machinery: Nws tuaj yeem muab faib ua cov ntawv tso tawm thiab lub vev xaib offset number case. SHEEDED OFFSKE INSET PERKS NROG RAUSE OFFSET NUM, UV Offset Ink, thiab Offset Ink Rau Cov Ntawv Hluav Taws Xob.
Los ntawm kev ziab txuj ci: nws suav nrog cov hom kev nkag mus ua kom qhuav, xws li lub vev xaib offset inks rau cov ntawv tshaj tawm; Oxidation kom qhuav hom, uas muaj polymers uas oxidize hauv huab cua los ua yeeb yaj kiab polymer; Thiab hom tshuab kom qhuav, qhov twg cov kuab tshuaj hauv cov kua memaporates los ua ib zaj duab xis.

1.Dab tsi yog qhov zoo ntawm number cask offset luam ntawv?

1. Kev dai me
Offset Tshuab Luam Ntawv Ink
Feem ntau yog dries los ntawm oxidation - polymerization. Inks muaj cov binders zoo li alkyd resins hnov ​​nrog oxygen rau saum huab cua. Sij hawm dhau mus, cov tshuaj lom neeg no ua rau cov ntoo khaub lig - txuas, khoom zaj duab xis. Piv txwv li, hauv ib daim ntawv - pub offset xovxwm, daim ntawv sau yog sab laug kom qhuav nyob rau hauv qhib cua, thiab auk maj mam tawv. Cov txheej txheem no tuaj yeem yog qeeb, tab sis nws muab cov advesion zoo thiab kav ntev.

UV - Inks Curable
Qhuav nrawm thaum raug rau ultraviolet (UV) lub teeb. Ib daim duab - tus pib hauv number case pib polymerization cov tshuaj tiv thaiv raws UV irradiation. Qhov no ua rau UV - decable inks zoo tshaj plaws rau kev loj - cov kab ntau lawm ceev, raws li tsis tas yuav tos tus mem kua txiv kom qhuav lawm. Piv txwv li, hauv cov ntawv lo rau load, qhov kev ua nrawm dua yog qhov tseem ceeb, UV - inks capable tuaj yeem kho tau hauv vib nas this.

Dej - raws inks
Qhuav tsuas yog los ntawm evaporation ntawm dej. Raws li cov dej nyob hauv lub number case evaporates rau hauv huab cua, cov pigments thiab binders yog sab laug los ua zaj duab xis qhuav. Lub sijhawm ziab tau cuam tshuam los ntawm cov khoom xws li cov av noo thiab kub. Hauv kev luam tawm ntawm cov ntxeem ntxeem tau zoo li ntawv zoo li ntawv zoo li cov ntawv, dej ntws tau sai sai, tab sis nyob rau hauv siab - cov txheej txheem huab cua ib puag ncig yuav tau qeeb qeeb.

2. Viscosity thiab hloov tshuab
Offset Tshuab Luam Ntawv Ink
Muaj ib qho nruab nrab - hom viscosity siab. Nws hloov pauv ntawm lub tshuab luam ntawv rau cov pam vov ntoo roj hmab thiab tom qab ntawd mus rau hauv substrate. Ink lub piscosity yuav tsum tau ua tib zoo tswj kom ntseeg tau tias hloov chaw kom zoo. Yog tias qhov viscosity dhau lawm, tus cwj mem yuav tsis hloov tusyees, ua rau muaj teeb meem xws li number cask. Yog tias nws qis dhau, dhau mus - inking thiab smudging tuaj yeem tshwm sim. Piv txwv li, hauv cov kab mob ua kom tsis zoo (nplaum) kuj ua lub luag haujlwm ntawm cov txheej txheem hloov ntawm cov khoom sib txawv ntawm cov xovxwm sib txawv.

Flexographic Inks
Muaj tsawg rau nruab nrab viscosity. Lawv pauv los ntawm anilox cov menyuam mus rau substrate. Lub viscosity tsawg tso cai rau tus number case kom ntws tau yooj yim los ntawm kev sau cov cells ntawm anilox cov menyuam. Qhov no tsim nyog rau kev sib xyaw ua ke zoo li cov yeeb yaj kiab yas thiab cov ntawv uas yuav tsum tau ua kom tiv thaiv cov teeb meem xws li tawg thaum lub substrate yog khoov.

Ntsuam Xyuas Luam Ntawv Inks
Yog ntau thicker nyob rau hauv ib txwm piv rau offset inks. Lawv raug yuam dhau ntawm lub ntxaij ntxaij mus rau hauv substrate. Lub siab viscosity ntawm kev tshuaj ntsuam - luam ntawv inks yog qhov tsim nyog los tswj kev ncaj ncees ntawm tus qauv ntawm kev tshuaj ntsuam thaum nws dhau ntawm lub vijtsam. Hom number case no tuaj yeem siv rau ntau hom substrates, los ntawm cov ntawv luam tawm rau iav, thiab tuaj yeem tsim cov ntawv luam tawm ntau dua thiab opaque.

3. Substrate compatibility
Offset Tshuab Luam Ntawv Ink
Adheres zoo rau ntau yam ntawm substrates, suav nrog ntau hom ntawv (coated, uncoated), duab los qhia txog, thiab qee yam plastics. Txawm li cas los xij, rau qee qhov tsis yog - ua ib txwm muaj - rau - luam tawm, tshwj xeeb pretreics, tshwj xeeb pretreitics, tshwj xeeb pretreatics ntawm lub xub ntiag lossis kev tsim tawm ntawm tus mem kua mem yuav tsum tau. Piv txwv li, hauv kev ntim luam ntawv, offset number case tuaj yeem siv rau ob daim ntawv - raws cartons thiab qee yam yas - coated laug cam.

Cov ntawv luam tawm digital (inkjet thiab toner)
Inkjet inks tau tsim los ua haujlwm zoo nrog cov ntawv luam tawm tshwj xeeb thiab hom ntawv. Lawv tau tsim los nqus tau sai sai rau hauv cov ntawv fibers los tiv thaiv cov smudging. Toner, siv nyob rau hauv laser printers, yog cov hmoov uas fuses rau substrate nyob rau hauv tshav kub thiab siab. Cov inks digital yuav muaj kev txwv ntawm ntau yam ntau yam piv rau kev luam tawm cov inks, tshwj xeeb yog los ntawm cov khoom siv ntxhib los yog tsis - nto moo thaj chaw tsis muaj kev kho mob tshwj xeeb.

Rotogravure inks
Feem ntau yog siv rau cov siab - ntim luam tawm ntawm cov kev hloov pauv ntawm cov ntawv yas yas, ntawv ci, thiab qee hom ntawv. Cov inks yuav tsum muaj cov dej ntws zoo los sau cov cawb kab engraved ntawm lub zog ntawm lub tog raj kheej. Lawv tau zoo rau kev txuas ntxiv - yob cov txheej txheem luam ntawv ntawm rotogravure presses.

4. Sau kom zoo thiab thov
Offset Tshuab Luam Ntawv Ink
Muaj peev xwm ua tiav siab - kev daws teeb meem luam tawm, muaj peev xwm ntawm cov ntsiab lus zoo, cov ntawv nyeem ntse, thiab cov xim du. Nws yog dav siv nyob rau hauv cov ntawv thov uas siab - zoo heev yog qhov yuav tsum tau, xws li hauv kev tshaj tawm cov ntawv kos duab, High - kawg cov khoom ntawv, thiab cov khoom ntim khoom. Ob - Kauj Ruam Hloov Cov txheej txheem (phaj rau pam vov) pab kom ua tiav qhov ntau txawm tias cov khoom xa tuaj, ua rau muaj kev sib xws thiab siab - ua tiav.

Ncoo Printing inks
Yog tsim rau kev luam tawm ntawm cov khoom tsis xwm yeem. Lawv muaj lub peev xwm los ua raws li cov duab ntawm cov khoom tau luam tawm. Ncoo luam ntawv Innks feem ntau yog siv rau kev luam tawm ntawm cov khoom zoo li cov khoom lag luam zoo li cov khoom lag luam zoo nkauj, cov khoom siv hluav taws xob me me, thiab qhov chaw tsheb. Cov ntawv luam tsis zoo yuav tsis yog qhov siab - daws teeb meem ua kev luam ntawv offset hauv qee kis, tab sis nws cov kev txawj ntse hauv kev luam tawm ntawm cov tsis yog - tiaj tiaj.
