Ishishini le-inki le-UV liphantsi kwenguqu ebalulekileyo eqhutywa kukunyuka kwemigangatho yendalo kunye nempilo. Eyona nto iphambili elawula imarike kukukhuthazwa kokwenziwa kwe-“NVP-Free” kunye “ne-NVC-Free”. Kodwa kutheni abavelisi be-inki besuka kwi-NVP nakwi-NVC?
Ukuqonda i-NVP kunye ne-NVC
**I-NVP (i-N-vinyl-2-pyrrolidone)** yi-nitrogen-equlethe i-diluent esebenzayo kunye ne-molecular formula C₆H₉NO, equkethe i-nitrogen-containing pyrrolidone ring. Ngenxa ye-viscosity ephantsi (ihlala inciphisa i-inki viscosity ukuya kwi-8–15 mPa·s) kunye nokusebenza kwakhona okuphezulu, i-NVP isetyenziswe kakhulu kwiingubo ze-UV kunye neenki. Nangona kunjalo, ngokwe-BASF's Safety Data Sheets (SDS), i-NVP ihlelwa njengeCarc. I-2 (H351: i-carcinogen ekrokrelwayo), i-STOT RE 2 (H373: umonakalo womzimba), kunye ne-Acute Tox. 4 (ityhefu ebukhali). I-American Conference of Governmental Industrial Hygienists (ACGIH) ithintele ngokungqongqo ukuba sesichengeni somsebenzi kwixabiso lomda womda (TLV) we-0.05 ppm kuphela.
Ngokufanayo, **NVC (N-vinyl caprolactam)** isetyenziswe ngokubanzi kwii-inks ze-UV. Malunga ne-2024, imimiselo ye-CLP ye-European Union yabela ukuhlelwa kweengozi ezintsha ze-H317 (i-skin sensitization) kunye ne-H372 (umonakalo wamalungu) kwi-NVC. Imixube ye-inki equlethe i-10 wt% okanye ngaphezulu kwe-NVC kufuneka ibonise ngokucacileyo uphawu lwengozi yokakayi kunye namathambo anqamlezayo, nto leyo eyenza kube nzima kakhulu ukwenziwa, uthutho, kunye nokufikelela kwimarike. Iimpawu ezibalaseleyo ezifana ne-NUtec kunye ne-swissQprint ngoku zibhengeza ngokucacileyo "i-NVC-i-inks ze-UV ezingenayo i-NVC" kwiiwebhusayithi zabo kunye nemathiriyeli yokuthengisa ukugxininisa iziqinisekiso zabo ze-eco-friendly.
Kutheni "i-NVC-Free" ibe yindawo yokuthengisa?
Kwiimpawu, ukwamkela "i-NVC-free" iguqulela kwiinzuzo ezininzi ezicacileyo:
* Ukuhlelwa kweengozi ezicuthiweyo ze-SDS
* Izithintelo zothutho ezisezantsi (azisahlelwa njengetyhefu 6.1)
* Ukuthobela ngokulula iziqinisekiso zokukhutshwa okuphantsi, okuluncedo ngakumbi kumacandelo anovakalelo afana neemeko zonyango kunye nezemfundo.
Ngamafutshane, ukuphelisa i-NVC kunika inqaku elicacileyo lokwahlula kwintengiso, isiqinisekiso esiluhlaza, kunye neeprojekthi zethenda.
Ubukho bembali ye-NVP kunye ne-NVC kwii-Inks ze-UV
Ukusukela ekupheleni koo-1990 ukuya ekuqaleni koo-2010, i-NVP kunye ne-NVC yayizii-diluants ezisebenzayo eziqhelekileyo kwiinkqubo ze-inki ze-UV ngenxa yokunciphisa i-viscosity esebenzayo kunye nokusebenza kwakhona okuphezulu. Ukuqulunqwa okuqhelekileyo kwee-inki ze-inkjet ezimnyama ngokwembali ziqulathe i-15-25 wt% NVP / NVC, ngelixa iingubo ezicacileyo ze-flexographic zine-5-10 wt%.
Nangona kunjalo, ekubeni i-European Printing Ink Association (i-EuPIA) yavala ukusetyenziswa kwe-carcinogenic kunye ne-mutagenic monomers, ukwakheka kwe-NVP yendabuko / i-NVC iguqulwa ngokukhawuleza ngezinye iindlela ezikhuselekileyo ezifana ne-VMOX, i-IBOA, kunye ne-DPGDA. Kubalulekile ukuqaphela ukuba i-solvent-based okanye i-inki esekwe emanzini ayizange ifake i-NVP/NVC; ezi lactam zevinyl ezinenitrogen ziye zafunyanwa kuphela kwiinkqubo zokunyanga iUV/EB.
Izisombululo ze-UV zeHaohui zabavelisi be-Ink
Njengenkokeli kumzi mveliso wokunyanga we-UV, iHaohui New Materials izinikele ekuphuhliseni i-inks ye-UV ekhuselekileyo, eco-friendly eco-friendly e-UV kunye neenkqubo zeresin. Sixhasa ngokukodwa abavelisi be-inki abaguqukayo ukusuka kwiinki zendabuko ukuya kwizisombululo ze-UV ngokujongana neendawo eziqhelekileyo zentlungu ngenkxaso yobugcisa obulungiselelwe. Iinkonzo zethu zibandakanya isikhokelo sokhetho lwemveliso, ukwenziwa ngcono kwemveliso, uhlengahlengiso lwenkqubo, kunye noqeqesho lobuchwephesha, okwenza ukuba abathengi bethu baphumelele phakathi kokuqina kwemithetho yokusingqongileyo.
