Bizinesi ya inki ya UV ikusintha kwambiri motsogozedwa ndi kukwera kwachilengedwe komanso thanzi. Chimodzi mwazinthu zazikulu pamsika ndikukweza mawu a "NVP-Free" ndi "NVC-Free". Koma nchifukwa chiyani kwenikweni opanga inki akuchoka ku NVP ndi NVC?
Kumvetsetsa NVP ndi NVC
**NVP (N-vinyl-2-pyrrolidone)** ndi nitrogen-container reactive diluent yokhala ndi formula ya molecular C₆H₉NO, yokhala ndi mphete ya pyrrolidone yokhala ndi nayitrogeni. Chifukwa cha kukhuthala kwake kochepa (nthawi zambiri kumachepetsa kukhuthala kwa inki kufika pa 8–15 mPa·s) komanso kuchitanso bwino kwambiri, NVP yakhala ikugwiritsidwa ntchito kwambiri mu zokutira za UV ndi inki. Komabe, malinga ndi BASF's Safety Data Sheets (SDS), NVP imatchedwa Carc. 2 (H351: okayikira carcinogen), STOT RE 2 (H373: kuwonongeka kwa chiwalo), ndi Acute Tox. 4 (chiwopsezo chachikulu). Bungwe la American Conference of Governmental Industrial Hygienists (ACGIH) lachepetsa kwambiri kuwonekera kwa ntchito pamtengo wocheperako (TLV) wa 0.05 ppm chabe.
Mofananamo, **NVC (N-vinyl caprolactam)** yagwiritsidwa ntchito kwambiri mu inki za UV. Cha m'ma 2024, malamulo a European Union a CLP adapereka magulu angozi atsopano a H317 (kulimbikitsa khungu) ndi H372 (kuwonongeka kwa ziwalo) ku NVC. Ma inki okhala ndi 10 wt% kapena kupitilira apo a NVC akuyenera kuwonetsa chizindikiro changozi ya chigaza cha chigaza ndi-crossbones, zomwe zimasokoneza kupanga, mayendedwe, ndi msika. Odziwika bwino monga NUtec ndi swissQprint tsopano akulengeza momveka bwino "ma inki a UV a NVC" pamasamba awo ndi zida zotsatsira kuti atsindike zomwe zimagwirizana ndi chilengedwe.
Chifukwa Chiyani "NVC-Free" Ikukhala Malo Ogulitsa?
Kwa mtundu, kugwiritsa ntchito "NVC-free" kumatanthawuza maubwino angapo:
* Kuchepetsa kwapang'onopang'ono kwa SDS
* Zoletsa zotsika (zosagawikanso ngati zapoizoni 6.1)
* Kutsatira mosavuta ziphaso zotulutsa mpweya wochepa, wopindulitsa makamaka m'magawo ovuta monga azachipatala ndi maphunziro.
Mwachidule, kuchotsa NVC kumapereka kusiyana koonekeratu pazamalonda, certification wobiriwira, ndi ntchito zachifundo.
Kukhalapo Kwakale kwa NVP ndi NVC mu Inks za UV
Kuyambira chakumapeto kwa zaka za m'ma 1990 mpaka koyambirira kwa 2010s, NVP ndi NVC zinali zodziwikiratu zodziwika bwino m'makina a inki amtundu wa UV chifukwa chochepetsa kukhuthala kwawo komanso kuchitanso bwino. Maonekedwe a inki yakuda ya inkjet m'mbiri yakale anali ndi 15-25 wt% NVP / NVC, pamene malaya owoneka bwino anali ndi 5-10 wt%.
Komabe, popeza European Printing Ink Association (EuPIA) idaletsa kugwiritsa ntchito carcinogenic ndi mutagenic monomers, mapangidwe achikhalidwe a NVP/NVC akusinthidwa mwachangu ndi njira zina zotetezeka monga VMOX, IBOA, ndi DPGDA. Ndikofunikira kudziwa kuti inki zosungunulira kapena zamadzi sizinaphatikizepo NVP/NVC; ma vinyl lactam okhala ndi nayitrogeniwa adapezeka m'machiritso a UV/EB okha.
Mayankho a Haohui UV kwa Opanga Ink
Monga mtsogoleri pamakampani opanga machiritso a UV, Haohui New Materials adadzipereka kupanga ma inki otetezeka, ochezeka a UV ndi makina a utomoni. Timathandizira makamaka opanga inki kuti asinthe kuchoka ku inki zachikhalidwe kupita ku njira za UV pothana ndi zowawa zomwe zimafala kudzera muzothandizira zamakono. Ntchito zathu zikuphatikiza chitsogozo chosankha zinthu, kukhathamiritsa kwa kapangidwe, kusintha kachitidwe, ndi maphunziro aukadaulo, kupangitsa makasitomala athu kuchita bwino pomwe akukhwimitsa malamulo a chilengedwe.
Kuti mumve zambiri zaukadaulo ndi zitsanzo zazinthu, pitani patsamba lovomerezeka la Haohui, kapena kulumikizana nafe pa LinkedIn ndi WeChat.
