Ink - Cov nplaum sib xyaw ua ke, cov yeeb yaj kiab zoo li no cuam tshuam nrog cov yeeb yaj kiab (motthing, thiab tev muaj zog (delamination los ntawm kev puas tsuaj hauv cov khaubncaws sab nraud povtseg). Qhov no feem ntau tshwm sim thaum cov pos hniav nkag mus los yog yaj cov ntawv luam tawm cov ntawv luam tawm.
1. Cov tshuaj tsis muaj txiaj ntsig ntawm number case (tshwj xeeb rau Esters): Qhov no yog feem ntau ua rau.
Lub ntsiab tivthaiv ntawm cov kua nplaum yog polyurethane Prepolymer, uas nws tus monomerhanate muaj cov pab pawg ua haujlwm (} NCO Seem Polyol Chain Seem Muaj Ester Bond (- coo}}}).
Ntau tus inks, tshwj xeeb yog polyamide - Raws li cov kev siv hluav taws xob lossis tshuaj lom neeg. Thaum tsawg {- viscosity, siab {{}}}}} este} estecentless cov tshuaj nplaum nyob rau hauv cov nplaum tuaj yeem yaj los yog offin binders nyob rau hauv number case. Qhov no ua rau cov pigment paltle rau tsiv teb tsaws chaw thiab disperse, kawg sib xyaw nrog cov nplaum.
Cov Cheeb Tsam nrog cov luam ntawv ntiav ntiav tshwj xeeb tshaj yog siv rau qhov no: cov chaw no muaj cov kua nplaum nyias nyias, ua kom yooj yim rau cov kua nplaum kom nkag rau hauv qab txheej los yog yaj txheej txheej hauv qab.
2. Kev xaiv tsis raug ntawm cov kua nplaum lossis cov yam ntxwv uas tsis zoo:
Cov nplaum tsis tshua muaj kev ua yeeb yam / qeeb kho ceev ceev: yog tias lub kua nplaum ua kom qeeb, cov kua nplaum nyob rau hauv lub cev nqaij daim tawv tom qab winding hauv qab kub thiab siab.
Qes kua nplaum viscosity (tshwj xeeb tshaj yog nyob rau hauv cov viscosity ib puag ncig): qhov muaj zog tshaj plaws thiab permeability, yooj yim rau infiltrate txheej. Kev kub siab ib puag ncig yuav cuam tshuam ntau cov viscosity ntawm cov kua nplaum.
Incomple kua nplaum nrog tus mem kua zog: qee yam ntawm cov kua nplaum tej zaum yuav muaj solubility ntau dua rau qee lub tshuab pa.
3. Tsis raug teeb tsa cov txheej txheem tsis sib haum:
Kev txiav ntau dhau: Ntau cov kua nplaum nce tag nrho cov nyiaj ntawm kev sib cuag nrog cov number case thiab osmotic siab.
Ntau dhau kev nqus hluav taws xob: ntau dhau los yuav txhaj cov kua nplaum rau hauv lub microporous txheej ntawm cov number case txheej, ua rau muaj kev nkag siab rau thiab ua tiav.
Ntau dhau ntawm cov kev ntxhov siab ntau dhau: kev tiv thaiv ntau dhau los yuav ua rau muaj kev sib cuag ntau dhau los, tshwj xeeb yog nyob rau hauv lub kauj, qhov twg qhov teeb meem yog feem ntau yuav tshwm sim nyob rau hauv cov siab kub.
Kev siv lub tshuab qeeb qeeb: Cov kua nplaum nyob qis qis dhau ntawm kev hloov pauv cov menyuam thiab ua ntej tshaj tawm, uas yuav ua rau cov neeg muaj kev sib xyaw ua ntej thiab ua ntej}}} kev tawm tsam, cuam tshuam rau theem thiab permeability. Nyob rau tib lub sijhawm, lub sijhawm raug hluav taws xob ua ntej cua kuj txuas ntxiv.
Ntau dhau los kho qhov kub lossis cua sov: kev kub siab yuav cuam tshuam nrawm ntawm cov kua nplaum rau cov kua nplaum rau cov kua nplaum kom tau ua rau txheej txheej tiv thaiv.
4. Cov khoom siv hauv paus thiab kev luam ntawv:
Tsawg lub zog ntawm cov ntawv luam tawm substrate / nyuaj cwj mem nplaum: yog tias tus cwj mem kua nplaum nws tus kheej tsis zoo rau lub substrate, kua nplaum muaj ntau dua "rub tawm" thiab muab cov number case.
Tsis txaus ua kom qhuav ntawm cov number case / residual Txawm li cas los xij, qhov point no muaj kev cuam tshuam tsawg dua li cov kuab yaj tiag.
Siab porosity ntawm number cas txheej / tsis tshua muaj kev siv lub zog: tus cwj pwm txheej txheej yog xoob lossis ntxeem tau rau cov xaim rau cov kua liab. Lub teeb xim mem kua los yog cov kua mem kua dawb nrog cov neeg tsis muaj zog zais lub zog yuav ua tau.
Siab stiffness substrate (piv txwv li bopp): cov ntaub ntawv uas muaj zog ruaj khov tsis tag tag los ntawm cov yob sib xyaw thiab cov hmoov av loj dua, nce cov kua nplaum ntau dua rau hauv tus mem kua.
5. Ib puag ncig cov ntsiab lus:
Ib puag ncig qhov kub yog qhov siab dhau: Raws li tau hais los saum toj no, nce qhov dej ntws, thiab nrawm dua cov tshuaj lom neeg (suav nrog kev sib cais).
Cov av noo siab: Cov av noo siab yuav cuam tshuam rau kev kho kua nplaum (noj - NCO lub sijhawm thaum cov kua nplaum ua haujlwm.
