Kev lag luam UV number case tau dhau los ua qhov kev hloov pauv tseem ceeb uas tau tsav los ntawm kev nce ib puag ncig thiab cov qauv kev noj qab haus huv. Ib qho kev sib tw loj tshaj plaws hauv kev ua lag luam yog kev nce qib ntawm "NVP-Free" thiab "NVC-Free" formulations. Tab sis vim li cas raws nraim cov tuam txhab luam ntawv txav deb ntawm NVP thiab NVC?
To taub NVP thiab NVC
**NVP (N-vinyl-2-pyrrolidone)** yog ib tug nitrogen-muaj reactive diluent nrog cov mis molecular C₆H₉NO, featuring ib tug nitrogen-muaj pyrrolidone nplhaib. Vim nws cov viscosity tsawg (feem ntau txo tus number case viscosity rau 8-15 mPa·s) thiab siab reactivity, NVP tau siv dav hauv UV txheej thiab inks. Txawm li cas los xij, raws li BASF's Safety Data Sheets (SDS), NVP tau muab cais ua Carc. 2 (H351: xav tias carcinogen), STOT RE 2 (H373: lub cev puas tsuaj), thiab mob hnyav. 4 (mob toxicity). Lub Rooj Sab Laj Tebchaws Asmeskas ntawm Tsoom Fwv Kev Ua Haujlwm Saib Xyuas Kev Noj Qab Haus Huv (ACGIH) tau txwv tsis pub ua haujlwm raug txwv rau qhov pib txwv tus nqi (TLV) tsuas yog 0.05 ppm.
Ib yam li ntawd, **NVC (N-vinyl caprolactam)** tau siv dav hauv UV inks. Nyob ib ncig ntawm 2024, European Union cov cai CLP tau muab cov kev faib phom sij tshiab H317 (kev hloov ntawm daim tawv nqaij) thiab H372 (kev puas tsuaj hauv nruab nrog cev) rau NVC. Ink formulations uas muaj 10 wt% lossis ntau dua NVC yuav tsum ua kom pom cov cim pob txha taub hau-thiab-crossbones txaus ntshai, cuam tshuam rau kev tsim khoom, kev thauj mus los, thiab kev lag luam. Cov npe nrov xws li NUtec thiab swissQprint tam sim no qhia meej meej tshaj tawm "NVC-dawb UV inks" ntawm lawv lub vev xaib thiab cov ntaub ntawv tshaj tawm los hais txog lawv cov ntawv pov thawj zoo.
Vim li cas "NVC-dawb" dhau los ua Qhov Muag Khoom?
Rau cov khoom lag luam, siv "NVC-dawb" txhais tau ntau yam txiaj ntsig:
* Txo kev faib cov kev phom sij ntawm SDS
* Kev txwv kev thauj mus los qis dua (tsis raug cais raws li tshuaj lom 6.1)
* Yooj yim ua raws li cov ntawv pov thawj qis qis, tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv cov haujlwm rhiab heev xws li kev kho mob thiab kev kawm ib puag ncig.
Hauv luv luv, tshem tawm NVC muab qhov sib txawv meej meej hauv kev lag luam, ntawv pov thawj ntsuab, thiab kev sib tw ua haujlwm.
Keeb kwm ntawm NVP thiab NVC hauv UV Inks
Los ntawm lig 1990s mus rau thaum ntxov 2010s, NVP thiab NVC yog cov reactive diluents nyob rau hauv cov tsoos UV number case systems vim lawv cov viscosity txo thiab siab reactivity. Cov qauv tsim rau cov xim dub inkjet keeb kwm muaj 15-25 wt% NVP / NVC, thaum flexographic clear coats muaj nyob ib ncig ntawm 5-10 wt%.
Txawm li cas los xij, txij li European Printing Ink Association (EuPIA) txwv tsis pub siv cov carcinogenic thiab mutagenic monomers, cov qauv NVP / NVC tau hloov pauv sai dua los ntawm kev nyab xeeb dua li VMOX, IBOA, thiab DPGDA. Nws yog ib qho tseem ceeb kom nco ntsoov tias cov kuab tshuaj raws li cov kuab tshuaj los yog dej-raws li inks yeej tsis suav nrog NVP / NVC; cov vinyl lactams uas muaj nitrogen no tsuas yog pom nyob rau hauv UV / EB curing systems.
