Daim Ntawv Thov Pseudo-boehmite hauv Ntawv Kev Lag Luam?

Pseudo-boehlitetau muab faib ua ob hom txij li thaum nws nkag mus rau lub hnub nyoog digital: resin thiab pigment. Resin suction duab inkjet daim ntawv txoj kev loj hlob tau nkag mus rau lub sijhawm tshiab, xws li cov txheej txheem ntawm tus number case dav xaiv ntawm absorbent o polymer, xws li: gelatin, hydroxyinkjet ntawv muag ntawm thawj lub tuam txhab Kodak, siv nws cov kev tshawb fawb muaj zog thiab kev loj hlob ntawm propyl cellulose. Tom qab tau txais cov kua mem kua rau saum npoo ntawm cov txheej txheej, cov neeg tsim khoom tau tsim cov ntsiab lus siab, siab ntom ntom duab inkjet luam ntawv ntawv. Nws nthuav me ntsis los tsim ib lub network thiab kos rau hauv tus number case drops.

Ink rau pigment inkjet luam ntawv, txawm tias nws yog dej-raws li lossis roj-raws li, hom number case absorbing txheej feem ntau muaj cov xim xim, xws li: amorphous ob viscosity yog me me, zoo heev, inkjet tshuab luam ntawv nozzle los ntawm vein silica, alumina , thiab lwm yam., nyob rau hauv lub txheej los tsim ib tug network ntawm ntau microholes, kev tswj ntawm tus number case droplet txhaj, txhua txhaj tshuaj ntawm number case droplet, nozzle kab noj hniav adsorption ntawm number case printing Cov nyhuv ntawm synfixation.

Hauv alumina, tus number case yog txhaj los ntawm kos, feem ntau muaj Y-AO. Nws yog siv rau 80 mus rau 200 microseconds, yog li cov kev ua ntawm cov xim inkjet yog ze heev rau cov macropore ntawm boehmite. Tab sis y-Al, O tom qab calcination yog siab. Thaum tus number case tuaj txog ntawm daim ntawv luam tawm, xav tau kev tshawb fawb ntxiv txog yuav ua li cas los tsim ib homogeneous txheej ntawm daim ntawv.
