Ke hele nei ka ʻoihana ʻīnika UV i kahi hoʻololi koʻikoʻi i hoʻokele ʻia e ka piʻi ʻana o nā kūlana kaiapuni a me ke olakino. ʻO kahi ʻano nui e noho aliʻi nei ma ka mākeke ʻo ia ka hoʻolaha ʻana o nā ʻano hana "NVP-Free" a me "NVC-Free". Akā no ke aha e neʻe nei nā mea hana ʻīnika mai NVP a me NVC?
Ka Hoʻomaopopo ʻana i ka NVP a me ka NVC
ʻO ka **NVP (N-vinyl-2-pyrrolidone)** he mea hoʻoheheʻe reactive i loaʻa ka naikokene me ke ʻano molekala C₆H₉NO, e hōʻike ana i kahi apo pyrrolidone i loaʻa ka naikokene. Ma muli o kona viscosity haʻahaʻa (e hoʻemi pinepine ana i ka viscosity o ka ʻīnika i 8-15 mPa·s) a me ke kiʻekiʻe o ka reactivity, ua hoʻohana nui ʻia ʻo NVP i nā uhi UV a me nā ʻīnika. Eia nō naʻe, e like me nā Palapala ʻIkepili Palekana (SDS) a BASF, ua hoʻokaʻawale ʻia ʻo NVP ʻo Carc. 2 (H351: i manaʻo ʻia he carcinogen), STOT RE 2 (H373: hōʻino ʻana o nā kino), a me Acute Tox. 4 (acute toxicity). Ua kaupalena loa ka ʻAha Kūkākūkā ʻAmelika o nā Hygienists ʻOihana Aupuni (ACGIH) i ka ʻike hana i kahi palena palena (TLV) o 0.05 ppm wale nō.
Pēlā nō, ua hoʻohana nui ʻia ka **NVC (N-vinyl caprolactam)** i nā ʻīnika UV. Ma kahi o 2024, ua hāʻawi nā lula CLP o ka ʻAhahui ʻEulopa i nā hoʻokaʻawale pōpilikia hou H317 (ʻili sensitization) a me H372 (pōʻino o ke kino) iā NVC. Pono nā ʻano ʻīnika e loaʻa ana he 10 wt% a ʻoi aku paha NVC e hōʻike maopopo i kahi hōʻailona pōpilikia iwi poʻo a me nā iwi keʻa, e hoʻopilikia nui ana i ka hana ʻana, ka lawe ʻana, a me ke komo ʻana i ka mākeke. ʻO nā lama kaulana e like me NUtec lāua ʻo swissQprint i kēia manawa ke hoʻolaha pololei nei i nā "ʻīnika UV ʻole NVC" ma kā lākou pūnaewele a me nā mea hoʻolaha e hoʻokūpaʻa i kā lākou mau hōʻoia aloha kaiapuni.
No ke aha i lilo ai ʻo "NVC-Free" i kumu kūʻai aku?
No nā lama, ʻo ka hoʻohana ʻana i ka "NVC-free" e unuhi ʻia i kekahi mau pono maopopo:
* Hoʻemi ʻia ka hoʻokaʻawale ʻana o ka pōʻino SDS
* Nā palena hoʻohaʻahaʻa no ka lawe ʻana (ʻaʻole i hoʻokaʻawale hou ʻia he mea ʻawahia 6.1)
* ʻOi aku ka maʻalahi o ka hoʻokō ʻana me nā palapala hōʻoia haʻahaʻa-hoʻokuʻu ʻana, he mea pono loa ia ma nā ʻāpana koʻikoʻi e like me nā wahi lapaʻau a me nā wahi hoʻonaʻauao.
I ka pōkole, ʻo ka hoʻopau ʻana i ka NVC e hāʻawi i kahi kiko ʻokoʻa maopopo i ke kūʻai aku ʻana, ka palapala hōʻoia ʻōmaʻomaʻo, a me nā papahana tender.
Ka Nohona Mōʻaukala o NVP a me NVC i nā ʻīnika UV
Mai ka hopena o nā makahiki 1990 a hiki i ka hoʻomaka ʻana o nā makahiki 2010, ʻo NVP a me NVC nā mea hoʻoheheʻe reactive maʻamau i nā ʻōnaehana ʻīnika UV kuʻuna ma muli o ko lākou hōʻemi ʻana i ka viscosity a me ke kiʻekiʻe o ka reactivity. ʻO nā ʻano maʻamau no nā ʻīnika inkjet ʻeleʻele i loaʻa i ka wā ma mua he 15-25 wt% NVP/NVC, ʻoiai ʻo nā ʻaʻahu maopopo flexographic he 5-10 wt%.
Eia nō naʻe, mai ka wā i pāpā ai ka European Printing Ink Association (EuPIA) i ka hoʻohana ʻana i nā monomers carcinogenic a me mutagenic, ua pani koke ʻia nā ʻano hana NVP/NVC kuʻuna e nā koho ʻē aʻe palekana e like me VMOX, IBOA, a me DPGDA. He mea nui e hoʻomaopopo ʻaʻole i hoʻokomo ʻia nā ʻīnika i hoʻokumu ʻia i ka solvent a i ʻole ka wai i ka NVP/NVC; ua loaʻa wale kēia mau vinyl lactams i loaʻa ka nitrogen i nā ʻōnaehana hoʻōla UV/EB.
Nā Hoʻonā UV Haohui no nā Mea Hana ʻInika
Ma ke ʻano he alakaʻi i ka ʻoihana hoʻōla UV, ua hoʻolaʻa ʻia ʻo Haohui New Materials i ka hoʻomohala ʻana i nā ʻōnaehana inika UV a me nā resin palekana a palekana i ke kaiapuni. Kākoʻo kūikawā mākou i nā mea hana inika e hoʻololi ana mai nā inika kuʻuna i nā hoʻonā UV ma o ka hoʻoponopono ʻana i nā pilikia maʻamau ma o ke kākoʻo loea i hoʻopilikino ʻia. Hoʻokomo pū ʻia kā mākou lawelawe i ke alakaʻi koho huahana, ka hoʻonui ʻana i ka hoʻohui ʻana, nā hoʻoponopono kaʻina hana, a me ke aʻo ʻoihana, e hiki ai i kā mākou mea kūʻai aku ke holomua i waena o ka hoʻopaʻa ʻana i nā lula kaiapuni.
No nā kikoʻī loea hou aku a me nā laʻana huahana, e kipa i ka pūnaewele kūhelu o Haohui, a i ʻole e hoʻopili mai me mākou ma LinkedIn a me WeChat.
