Inganda za UV zirimo guhinduka cyane biterwa no kuzamuka kw’ibidukikije n’ubuzima. Imwe mu nzira nyamukuru yiganje ku isoko ni ugutezimbere "NVP-Free" na "NVC-Free". Ariko ni ukubera iki mubyukuri abakora wino bagenda kure ya NVP na NVC?
Gusobanukirwa NVP na NVC
** NVP. Bitewe n'ubukonje buke (akenshi bigabanya ubukonje bwa wino kugera kuri mPa 8-15) hamwe nubushake buke, NVP yakoreshejwe cyane mumyenda ya UV na wino. Nyamara, ukurikije urupapuro rwumutekano rwa BASF (SDS), NVP ishyirwa mubikorwa nka Carc. 2 (H351: ukekwaho kanseri), STOT RE 2 (H373: kwangirika kwingingo), nuburozi bukabije. 4 (uburozi bukabije). Ihuriro ry’Abanyamerika ry’abashoramari bo mu nganda za Leta (ACGIH) ryagabanyije cyane akazi ku gipimo ntarengwa (TLV) cya 0.05 ppm.
Mu buryo nk'ubwo, ** NVC (N-vinyl caprolactam) ** yakoreshejwe cyane muri wino ya UV. Ahagana mu 2024, amabwiriza y’ubumwe bw’ibihugu by’Uburayi yashyizeho ibyiciro bishya bya H317 (sensibilisation y’uruhu) na H372 (kwangiza ingingo) kuri NVC. Inkingi ya wino irimo 10 wt% cyangwa irenga NVC igomba kwerekana cyane ikimenyetso cya gihanga-gihanga-gihanga, bigoye cyane gukora, gutwara, no kubona isoko. Ibirango bizwi nka NUtec na swissQprint ubu byamamaza ku buryo bweruye "inkingi ya UV idafite UV" ku mbuga zabo ndetse n'ibikoresho byamamaza kugira ngo bashimangire ibyangombwa byabo bitangiza ibidukikije.
Kuki "NVC-Yubusa" Ihinduka Igurishwa?
Kubirango, kwemeza "NVC-free" bisobanura inyungu nyinshi zisobanutse:
* Kugabanya ibyiciro bya SDS
* Imbogamizi zo gutwara abantu (ntizishyirwa muburozi 6.1)
* Kubahiriza byoroshye ibyemezo byoherezwa mu kirere, cyane cyane mubyiciro byoroshye nkubuvuzi nuburezi.
Muri make, gukuraho NVC bitanga itandukaniro rigaragara mubucuruzi, ibyemezo byicyatsi, hamwe nimishinga itanga isoko.
Kubaho Amateka ya NVP na NVC muri UV Inks
Kuva mu mpera z'imyaka ya za 90 kugeza mu ntangiriro ya za 2010, NVP na NVC byari ibintu bisanzwe byifashishwa muri sisitemu ya wino gakondo ya UV bitewe no kugabanya ubukonje bwabyo no kongera gukora cyane. Ubwoko busanzwe bwa wino ya wino yumukara mumateka yarimo 15-25 wt% NVP / NVC, mugihe amakoti asobanutse ya flexographic yari afite hafi 5-10 wt%.
Ariko, kubera ko Ishyirahamwe ry’iburayi ryandika (EuPIA) ryabujije ikoreshwa rya kanseri ya kanseri na mutagenic, imiti gakondo ya NVP / NVC isimburwa byihuse n’ubundi buryo butekanye nka VMOX, IBOA, na DPGDA. Ni ngombwa kumenya ko wino-ishingiye kumazi cyangwa wino ishingiye kumazi itigeze ishyiramo NVP / NVC; aya azote arimo vinyl lactam yabonetse gusa muri sisitemu yo gukiza UV / EB.
Haohui UV Ibisubizo kubakora Ink
Nkumuyobozi mubikorwa byo gukiza UV, Haohui Ibikoresho bishya byiyemeje guteza imbere inkingi za UV zifite umutekano, zangiza ibidukikije hamwe na sisitemu ya resin. Dushyigikiye byimazeyo abakora wino bava muri wino gakondo bakajya mubisubizo bya UV dukemura ibibazo byububabare busanzwe binyuze mubufasha bwa tekiniki bwihariye. Serivisi zacu zirimo kuyobora ibicuruzwa, guhitamo uburyo bwiza, guhindura imikorere, hamwe namahugurwa yumwuga, bituma abakiriya bacu batera imbere mugihe hagaragaye amategeko agenga ibidukikije.
Kubindi bisobanuro bya tekiniki hamwe nicyitegererezo cyibicuruzwa, sura urubuga rwemewe rwa Haohui, cyangwa uhuze natwe kuri LinkedIn na WeChat.
