Ink yog qhov muaj kuab paug loj tshaj plaws ntawm kev lag luam luam ntawv; lub ntiaj teb txhua xyoo tso zis ntawm tus number case tau mus txog 3 lab tons. Txhua xyoo thoob ntiaj teb organic volatile teeb meem (VOC) cov pa phem emissions los ntawm number case tau mus txog ntau pua txhiab tons. Cov organic volatiles tuaj yeem tsim cov tsev cog khoom hnyav dua li cov pa roj carbon dioxide, thiab nyob rau hauv irradiation ntawm lub hnub ci yuav tsim oxides thiab photochemical pa luam yeeb, muaj kuab paug loj ntawm atmospheric ib puag ncig, cuam tshuam rau tib neeg kev noj qab haus huv. Tam sim no, lub ntsiabib puag ncig tiv thaiv number casemuaj cov nram qab no:
1) Cov kua dej ua kua
Cov kua dej ua kua siv dej ntau dua li cov kuab tshuaj organic, uas txo qis VOC emissions thiab tsis cuam tshuam rau tib neeg kev noj qab haus huv. Nws tsis yooj yim rau hlawv, tus number case ruaj khov, ci xim, tsis corrode lub phaj, kev ua haujlwm yooj yim, pheej yig tus nqi, zoo adhesion tom qab luam ntawv, muaj zog dej tsis kam, ceev kom qhuav. Nws yog lub ntiaj teb lees paub ib puag ncig tiv thaiv luam ntawv khoom.
2) UV curable number case
UV number case yog hais txog kev siv lub teeb UV, nrog rau qhov sib txawv wavelengths thiab lub zog nyob rau hauv UV irradiation los ua tus number case zaj duab xis curing. Siv uv spectral zog, tus number case binder nyob rau hauv lub polymerization ntawm monomers rau hauv polymers, Yog li UV number case xim zaj duab xis muaj zoo txhua yam thiab tshuaj zog. Tam sim no UV number case tau dhau los ua cov tshuab luam ntawv paub tab, nws cov pa paug tawm tsawg heev. Ntxiv rau qhov tsis muaj kuab tshuaj, UV number case tsis yooj yim rau paste, ntshiab dot, ci xim, zoo heev tshuaj tiv thaiv, noj, thiab lwm yam zoo.
3) Soy-based number case
Soy-based number case yog ua los ntawm cov kua txiv hmab txiv ntoo uas tau noj tau (lossis lwm cov roj zaub qhuav lossis ib nrab qhuav) sib xyaw nrog cov xim, resins, waxes thiab lwm yam. Cov number case no tsis muaj cov organic tebchaw uas ua rau cov pa phem, tsis muaj ntxhiab, tsis muaj tshuaj lom, nws maj mam hloov cov ntxhia roj number case. Nws cov koob meej thiab kev nce qib yog nrawm heev hauv Tebchaws Europe, Nyiv thiab Tebchaws Meskas.
4) Water-based UV number case
Dej-raws li UV number case yog nyob rau hauv UV number case ntxiv ib tug npaum li cas ntawm cov dej thiab 5%kev tiv thaiv ib puag ncighnyav, ua ke nrog tshwj xeeb dej-raws li resin. Qhov no ua rau tus cwj mem tsis tsuas yog khaws cov txiaj ntsig ntawm UV number case curing ceev, txuag hluav taws xob, hneev taw me me, kev tiv thaiv ib puag ncig, tab sis kuj ua kom tiav cov number case curing, noo noo volatilization, kom cov number case txheej thinning printing yuav tsum. Tus cwj mem no yog ib qho kev tshawb fawb tshiab hauv daim teb ntawm UV number case.
5) Alcohol-soluble number case
Cawv-soluble number case yog raws li ethanol (cawv) ua cov kuab tshuaj tseem ceeb, tsis muaj tshuaj lom, muaj kev nyab xeeb, kev tiv thaiv ib puag ncig, kev noj qab haus huv, yog qhov zoo tshaj plaws hloov cov khoom siv yas yas. Nyob rau hauv South Kauslim, Singapore, cawv soluble number case tau hloov toluene number case. Cov dej cawv-soluble number case feem ntau ua lub luag haujlwm hauvua flexonws tseem yog eco-friendly number case.
