Ụlọ ọrụ ink UV na-enwe mgbanwe dị ịrịba ama na-ebute site n'ịkwalite ụkpụrụ gburugburu ebe obibi na ahụike. Otu isi ihe na-eme n'ahịa bụ nkwalite nke usoro "NVP-Free" na "NVC-Free". Mana gịnị kpatara kpọmkwem ndị na-emepụta ink na-apụ na NVP na NVC?
Ịghọta NVP na NVC
**NVP (N-vinyl-2-pyrrolidone)** bụ ihe na-emeghachi omume nitrogen nwere usoro mkpụrụ ndụ C₆H₉NO, na-egosipụta mgbanaka pyrrolidone nwere nitrogen. N'ihi viscosity ya dị ala (na-ebelata viscosity ink na 8-15 mPa·s) yana mmeghachi omume dị elu, NVP ejirila ọtụtụ ihe na mkpuchi UV na ink. Agbanyeghị, dịka BASF's Safety Data Sheets (SDS), NVP bụ nkewa dị ka Carc. 2 (H351: a na-enyo enyo carcinogen), STOT RE 2 (H373: mmebi akụkụ ahụ), na nnukwu Tox. 4 (nnukwu nsi). Nzukọ America nke Gọọmenti Industrial Hygienists (ACGIH) nwere oke oke ọrụ ekpughere ọnụ ahịa oke ọnụ (TLV) nke naanị 0.05 ppm.
N'otu aka ahụ, ** NVC (N-vinyl kaprolactam)** ejirila ya n'ọrụ na ink UV. N'ihe dị ka afọ 2024, ụkpụrụ CLP nke European Union kenyere nhazi ihe egwu ọhụrụ H317 (nhụta anụ ahụ) na H372 (mmebi akụkụ ahụ) na NVC. Usoro ink nwere 10 wt% ma ọ bụ karịa NVC ga-egosipụtarịrị akara egwu okpokoro isi na ọkpụkpụ, na-akpaghasị nrụpụta, njem, na ịnweta ahịa. Ụdị ndị a ma ama dị ka NUtec na swissQprint na-akpọsa n'ụzọ doro anya "ink UV na-enweghị NVC" na webụsaịtị ha na ihe nkwado iji mesie nzere eco-eco-friendly ha.
Kedu ihe kpatara "NVC-free" ji bụrụ ebe a na-ere ere?
Maka ụdịdị, ịnakwere “NVC-free” tụgharịrị gaa na ọtụtụ uru doro anya:
* Mbelata nkewa ihe egwu SDS
* Mgbochi ụgbọ njem dị ala (anaghị ekewa ya dị ka 6.1 na-egbu egbu)
* Nrube isi dị mfe na asambodo dị ala, bara uru na mpaghara ndị nwere mmetụta dị ka gburugburu ahụike na agụmakwụkwọ.
Na nkenke, iwepụ NVC na-enye ihe dị iche iche doro anya na ahịa, akwụkwọ ndụ akwụkwọ ndụ akwụkwọ ndụ, na ọrụ nro.
Ọnụnọ akụkọ ihe mere eme nke NVP na NVC na UV Inks
Site na ngwụcha 1990s ruo mmalite 2010s, NVP na NVC bụ ihe na-emeghachi omume na sistemu ink UV ọdịnala n'ihi mbelata viscosity ha dị mma na mmeghachi omume dị elu. Ụdị usoro maka inkjet ojii nwere akụkọ ihe mere eme nwere 15-25 wt% NVP/NVC, ebe uwe mkpuchi doro anya nwere ihe dịka 5-10 wt.
Otú ọ dị, ebe ọ bụ na European Printing Ink Association (EuPIA) machibidoro iji carcinogenic na mutagenic monomers, usoro NVP/NVC omenala na-eji ihe ndị ọzọ dị nchebe dochie ngwa ngwa dị ka VMOX, IBOA, na DPGDA. Ọ dị mkpa iburu n'obi na inks dabere na ihe mgbaze ma ọ bụ mmiri anaghị etinye NVP/NVC; vinyl lactams ndị a nwere nitrogen bụ naanị n'ime usoro ọgwụgwọ UV/EB.
Ngwọta Haohui UV maka ndị nrụpụta ink
Dịka onye ndu n'ime ụlọ ọrụ ọgwụgwọ UV, Haohui New Materials raara onwe ya nye iji wulite inks UV na resin dị mma, enyi na enyi. Anyị na-akwado kpọmkwem ndị na-emepụta ink na-agbanwe site na ink ọdịnala gaa na ngwọta UV site na ịza ihe mgbu na-emekarị site na nkwado ọrụ aka ahaziri. Ọrụ anyị gụnyere ntụzịaka nhọrọ ngwaahịa, njikarịcha nhazi, nhazi usoro, yana ọzụzụ ọkachamara, na-enyere ndị ahịa anyị aka ime nke ọma n'etiti iwusi ụkpụrụ gburugburu ebe obibi.
