Cov teeb meem thiab cov kev daws teeb meem uas yuav tshwm sim thaum luam ntawv lub hnab ntim nrog number case:
1. Tsis zoo adhesion
Ua rau tsis ua hauj lwm:
(1) Qhov saum npoo ntawm lub hnab ntim khoom thiab cov txheej los yog lub ntsej muag ntawm lub hnab ntim khoom yog du heev (tsis kho lossis kho tsis zoo) (2) Lub complex (ie, additive) ntawm tus number case yog xaiv tsis raug lossis ntau npaum li cas tsis txaus.
(3) Lub solubility hydrogen bond quab yuam ntawm tus number case system txawv dhau ntawm lub hnab woven substrate.
Txoj kev daws teeb meem:
(1) Qhov saum npoo ntawm lub hnab woven substrate ncav cuag li 38 dynes.
(2) Ntxiv 5% chlorinated paraffin ua ntej ncab cov xov paj yas.
(3) Kev xaiv tus cwj mem yuav tsum ceev faj heev (zoo tib yam).
(4) Kev siv tus cwj mem yuav tsum tsim nyog, thiab cov txheej txheem number case uas tsis muaj viscosity thiab cov ntsiab lus siab resin yog nyiam.
(5) Ua kom muaj kev luam ntawv siab.
2. Adhesion ntawm cov khoom luam tawm
Ua rau tsis ua hauj lwm:
(1) Lub hnab lo ua ke thaum luam ntawv thiab stacking lossis tom qab rewinding.
(2) Lub tshuab luam ntawv nrawm nrawm dhau thiab rov ua dua yog nruj heev.
(3) Lub kaum sab xis ntawm lub tshuab ziab khaub ncaws tsis raug lossis ua haujlwm tsis zoo tshwm sim.
(4) Tus number case dries qeeb heev.
(5) Lub thawv ntim khoom hnyav dhau.
(6) Qhov kub thiab txias yog siab dhau thiab txias tsis tiav lossis tus number case tsis kub-resistant.
(7) Tus number case yog nyias heev thiab nkag mus rau sab nraum qab ntawm cov ntawv luam.
Txoj kev daws teeb meem:
(1) Kho lub tshuab luam ntawv ceev thiab xyuas lub kaum sab xis ntawm lub tshuab ziab khaub ncaws.
(2) Txhim kho qhov ziab ntawm tus number case (los yog nce tus nqi ntawm 90% ethanol + 10% ethyl ester tov diluent).
(3) Stackless thaum luam ntawv lossis ua kom lub teeb ntim khoom ntim.
(4) Txo qhov kub ntawm lub rhiav lossis warehouse (qhib qhov rais thiab lub qhov rooj kom tso cua convection, thiab lwm yam), thiab hloov lub tshav kub-resistant woven hnab number case.
(5) Ntxiv cov ntawv nyoos los ua kom nws cov viscosity los yog ntxiv cov diluent nrog me me molecular hnyav thiab ceev evaporation (nws raug nquahu kom siv cov diluent tshwj xeeb uas tsim los ntawm lub Hoobkas number case).
3. Cov ntxhiab tsw qab
Ua rau tsis ua haujlwm:
(1) Cov khoom siv ntxhiab tsw hauv tus cwj mem.
(2) Ink deterioration.
Txoj kev daws teeb meem:
(1) Tsis txhob siv cov khoom siv ntxhiab tsw ntau li ntau tau.
(2) Ntxiv flavoring (odor masking agent) thiab tiv thaiv impurities los ntawm nkag mus rau tus number case system.
(3) Ua tib zoo saib xyuas cov solubility ntawm cov kuab tshuaj sib xyaw hauv cov resins thaum lub sij hawm tsim cov number case los yog khaws cov inks nyob rau hauv qhov cua thiab txias warehouses.
4. Kev tsim cov yeeb yaj kiab tsis zoo
Ua rau tsis ua haujlwm:
(1) Lub tshuab luam ntawv ceev tsis sib xws nrog cov tshuab ziab khaub ncaws lossis cov cuab yeej ua kom qhuav.
(2) Kev siv tsis raug ntawm diluent.
(3) Tus number case nws tus kheej tsis qhuav zoo (xws li qeeb lossis nrawm dhau).
Txoj kev daws teeb meem:
(1) Ua kom cov cua tshuab los yog nce (txuas ntxiv) tom qab luam ntawv conveyor siv.
(2) Kho lub tshuab luam ntawv ceev (them lub thickness ntawm tus number case zaj duab xis tom qab luam ntawv).
(3) Hloov cov ntaub ntawv ceev ceev (film-forming) number case.
(4) Hloov tus cwj mem.
(5) Re-dilute los yog ntxiv cov kuab tshuaj nrog tus nqi evaporation ceev.
5. Phaj thaiv
Ua rau tsis ua haujlwm:
(1) Qhov laj thawj tseem ceeb yog tias tus number case ntawm lub phaj luam ntawv yog qhuav, uas ua rau tus number case hloov tsis zoo.
(2) Cov ntaub ntawv yas los yog cov ntaub ntawv sib xyaw ua ke.
(3) Ink crusting.
Txoj kev daws teeb meem:
(1) Kho lub tshuab lub kaum sab xis (tsis txhob tshuab ncaj qha mus rau lub phaj luam ntawv).
(2) Ntxiv nrog rau kev hloov cov substrate, tus cwj mem tus cwj mem yuav tsum tau muab cais tawm ntawm lub hauv paus ntawv, yas los yog zaj duab xis nyob rau sab sauv ntawm lub tshuab luam ntawv.
(3) Hloov nrog tus cwj mem tshiab lossis ntxiv 10% antioxidant rau tus cwj mem.
6. Luam tawm los yog tsiv teb tsaws
Ua rau tsis ua hauj lwm:
(1) Tus number case yog nyias dhau (xws li cov viscosity tsawg dhau).
(2) Cov ntawv lossis yas substrate yog xoob thiab nyias.
(3) Tus number case loj dhau.
(4) Lub siab luam ntawv hnyav dhau.
(5) Cov zaj duab xis yog qeeb heev kom qhuav.
Txoj kev daws teeb meem:
(1) Ntxiv cov kua nplaum los yog cov tuab tuab.
(2) Hloov cov substrate ntom.
(3) Siv tus cwj mem nrog cov khoom kom qhuav zoo lossis ntxiv cov kuab tshuaj uas evaporate sai.
(4) Kho (txo) tus cwj mem muab.
(5) Lub siab luam ntawv yuav tsum yog lub teeb.
7. Xim los ntshav
Ua rau qhov teeb meem:
(1) Xim nkag los ntawm ntug ntawm daim duab luam tawm (feem ntau yog vim siv cov dyes hauv tus number case).
(2) Cov pigments siv tsis zoo sib xws los yog tus number case tau ua rancid thiab deteriorated.
(3) Kev siv cov thinner ntau dhau, tshwj xeeb tshaj yog thaum lub thinner thiab number case tsis zoo solubility.
Txoj kev daws teeb meem:
(1) Ntxiv kub tinting roj los yog coupling tus neeg sawv cev rau tus number case.
(2) Xaiv cov kuab tshuaj (xws li cawv hnyav) hom xim lossis hloov nrog tus cwj mem tshiab.
(3) Siv me ntsis thinner li sai tau, tshwj xeeb tshaj yog cov kuab tshuaj uas muaj miscible nrog tus number case.
8. Zaj duab xis npub
Ua rau qhov teeb meem:
(1) Gloss tsis zoo.
(2) Whitening vim yog nqus dej thaum lub sijhawm tsim cov yeeb yaj kiab.
(3) Rough number case.
(4) Tus number case dries sai heev.
(5) Lub tshuab number case muaj cov resin tsawg dhau los yog tus neeg sawv cev matting tsis raug ntxiv. Thaum lub caij ntuj sov, thaum kub thiab av noo yog siab, tshwj xeeb tshaj yog nyob rau hauv cov ntug hiav txwv dej, tus number case absorbs noo noo los ntawm huab cua thaum lub sij hawm luam ntawv txheej txheem thiab puas oiliness, yog li txo cov gloss.
Txoj kev daws teeb meem:
(1) Ntxiv 3% mus rau 5% cyclohexanone los yog 2% mus rau 4% ether rau tus number case los tiv thaiv kev cuam tshuam ntawm cov dej molecules.
(2) Regrind lossis lim cov number case.
(3) Siv cov kuab tshuaj kom qhuav kom qhuav los ntxiv rau lub tshuab number case.
(4) Ntxiv 5% mus rau 15% resin kua rau hauv tus cwj mem.
(5) Sim tsis txhob ntxiv lossis ntxiv cov tshuaj matting tsawg (xws li siv quav ciab, dawb carbon dub, thiab lwm yam).
(6) Hloov tus cwj mem nrog lub ntsej muag zoo dua lossis siv cov kuab tshuaj tsawg dua.
