Dab tsi yog water-base printing number case:

Dej-puag luam ntawv number case yog ib yam khoom muab tshuaj txhuam uas muaj li ntawm binders, pigments, additives thiab lwm yam.Lub binder muab qhov tsim nyog hloov kev ua tau zoo ntawm tus number case, thiab cov pigment muab tus number case nws cov xim.Cov binder ntawm dej-base number case yog feem ntau muab faib. ua ob hom: hom dej dilution thiab dej dispersion hom.

Muaj ntau ntau hom resins uas tuaj yeem siv rau hauv dej dilution inks, xws li Maleic acid resin, Shellac, Maleic acid resin modified shellac, Urethane, Dej-soluble acrylic resin thiab Dej-raws li amino resin.

Cov dej dispersion binder yog tau los ntawm polymerizing monomers emulsified hauv dej.Nws yog ob-theem system uas cov roj theem yog dispersed nyob rau hauv cov dej theem nyob rau hauv daim ntawv ntawm hais.Txawm hais tias nws tsis tuaj yeem yaj los ntawm dej, tab sis tuaj yeem diluted los ntawm dej.Nws tuaj yeem suav hais tias yog hom roj-hauv-dej emulsion.

Kev sib piv ntawm cov dej-base number case thiab roj-base ink:

Water-base printing number case:

Tus number case muaj cov cwj pwm ruaj khov thiab cov xim ci ntsa iab.Cov dej-piv tus number case yog npaj los ntawm dej-raws li resin, uas tuaj yeem diluted nrog dej, muaj VOC tsawg heev (volatile organic compound) cov ntsiab lus, muaj cov pa phem tsawg, tsis cuam tshuam rau tib neeg. Kev noj qab haus huv, thiab tsis yooj yim rau hlawv.Nws yog ib puag ncig tus phooj ywg number case.Qhov tseem ceeb rau cov dej-puag inks yog adhesion zoo thiab dej tsis kam.Feem ntau siv rau hauv cov khoom noj, tshuaj, dej haus thiab lwm yam lag luam, ntim thiab luam ntawv kev lag luam kuj tau siv dav.

Roj-base luam ntawv number case:

Cov roj hauv paus inks siv cov kuab tshuaj organic (Toluene, Xylene, Muaj cawv, thiab lwm yam) ua cov kuab tshuaj, tab sis qhov tsis haum ntawm cov kuab tshuaj yuav ua rau ib puag ncig.Roj hauv paus number case tuaj yeem luam tawm ntawm qhov nqus thiab tsis nqus dej, thiab xim tsis yooj yim rau ploj tom qab luam ntawv.Roj-puag inks yog tus cwj pwm los ntawm siab viscosity, ceev kom qhuav, dej tsis kam, softness, thiab lub teeb tsis kam.

Tag nrho peb cov yeeb yaj kiab PVC zoo nkauj yog luam tawm nrog dej-puab inks, uas tsis muaj kuab paug rau ib puag ncig thiab tsis muaj mob rau tib neeg lub cev!
