Cov nplaum polyurethane yog siv dav hauv ntau lub teb vim lawv cov khoom zoo. Rau ntau qhov kev lag luam, nws yog qhov tsis txaus ntseeg qhov yuav tawm ntawm nws. Kuv tsis txhob' t paub yog tias koj tau nkag siab tias kev siv cov nplaum no tuaj yeem ua kua mem ntsej muag rau luam ntawv, yog li nws tuaj yeem txhawb nqa thiab siv hauv kev lag luam luam ntawv. Cia' s kawm txog qhov kev paub no:
Cov dej nyob hauv tus number case yog cov xaiv thawj zaug rau kev luam ntawv rau ib puag ncig. Chav ntsuas kub ua kom sib txuas nrog cov dej ua kua nplaum polyurethane nplaum tuaj yeem siv los ua cov khoom tiv thaiv ib-tivthaiv polyurethane dej-ua kua xim haum rau gravure luam ntawv. Cov dej nyob hauv tus number case muaj lub siab gloss, dej tsis kam, muaj zog adhesion, kho tau dryness, xim ci, cov khaubncaws sab nraud povtseg, tsis muaj tshuaj lom, tsis kub nyhiab, huab cua tsis haum, khov thiab tswj tau yooj yim, Nws muaj ntau yam yoog raws. ntau yam khoom siv substrate.
Lub hauv paus zaj duab xis siv nyob rau hauv kev lag luam xim luam ntawv feem ntau suav nrog polyester zaj duab xis, nylon zaj duab xis, polypropylene zaj duab xis, polyethylene zaj duab xis, thiab lwm yam. Siv vinyl chloride-hydroxyethyl acrylate copolymer muaj cov hydroxyl pawg nyob rau hauv cov txheej txheem molecule kom hnov mob nrog macromolecular diols, cov xov tooj me me molecule saw txuas ntxiv, thiab toluene diisocyanate, ib hom tshiab ntawm polyurethane nplaum tuaj yeem npaj, uas tuaj yeem txhim kho qhov zoo ntawm cov xim luam ntawv inks.
Hauv txoj kev xaus, cov inks ua los ntawm polyurethane cov nplaum tau siv dav hauv luam ntawv thiab ntim, cov khoom lag luam number case, thiab muaj kev nyab xeeb dua thiab huv dua li lwm cov dej ntim. Nrog kev txhim kho ntawm tib neeg' s kev paub txog kev tiv thaiv ib puag ncig, polyurethane yog maj mam raug nce thiab ntau thiab ntau tus neeg tau them ntau dua thiab ntau rau nws. Nws siv tseem tau nthuav dav, thiab nws yuav pom nyob rau ntau daim teb yav tom ntej.
