Impamvu irangi rya UV "ridafite NVP" na "ridafite NVC" ririmo guhinduka umurongo ngenderwaho mu nganda nshya

Inganda zikora irangi rya UV ziri mu mpinduka zikomeye ziterwa n’izamuka ry’ibipimo by’ibidukikije n’ubuzima. Imwe mu nzira ikomeye yiganje ku isoko ni uguteza imbere imiterere ya “NVP-Free” na “NVC-Free”. Ariko se kuki abakora irangi barimo kuva kuri NVP na NVC?

Gusobanukirwa NVP na NVC

**NVP (N-vinyl-2-pyrrolidone)** ni umuti ugabanya azote urimo formula ya molekile C₆H₉NO, ifite impeta ya pyrrolidone irimo azote. Bitewe n'uko ifite ubukana buke (akenshi igabanya ubukana bwa wino kugeza kuri 8–15 mPa·s) ndetse n'ubukana bwinshi, NVP yakoreshejwe cyane mu gutwikira no gusiga UV. Ariko, nk'uko BASF's Safety Data Sheets (SDS) ibigaragaza, NVP ishyirwa mu cyiciro cya Carc. 2 (H351: kanseri ikekwaho), STOT RE 2 (H373: kwangirika kw'ingingo), na Acute Tox. 4 (uburozi bukomeye). Inama y'Abanyamerika y'Abakozi ba Leta mu by'Isuku mu Nganda (ACGIH) ifite ubushobozi buke bwo kugera ku gaciro k'umupaka (TLV) ka 0.05 ppm gusa.

Mu buryo nk'ubwo, **NVC (N-vinyl caprolactam)** yakoreshejwe cyane mu irangi rya UV. Ahagana mu 2024, amabwiriza ya CLP y'Umuryango w'Ubumwe bw'u Burayi yahaye NVC ibyiciro bishya bya H317 (kumenya uruhu) na H372 (kwangirika kw'ingingo). Inyito za wino zirimo 10% cyangwa zirenga NVC zigomba kugaragaza neza ikimenyetso cy'ibyago by'umutwe n'amagufwa, bikagira ingaruka mbi ku buryo bukabije ku nganda, ubwikorezi, no kugera ku isoko. Ibigo bizwi nka NUtec na swissQprint ubu byamamaza ku buryo bweruye "inyito za UV zidafite NVC" ku mbuga zabo za interineti n'ibikoresho byo kwamamaza kugira ngo bishimangire ubwiza bwazo bworohereza ibidukikije.

Kuki "Nta NVC-Free" ihinduka ahantu ho kugurisha?

Ku birango, gukoresha "nta NVC" bivuze inyungu nyinshi zigaragara:

* Kugabanya ishyirwa mu byiciro ry'ibyago bya SDS

* Kugabanya amabwiriza yo gutwara ibintu (ntibikiri mu cyiciro cy’uburozi 6.1)

* Kubahiriza byoroshye ibyemezo by’imyuka ihumanya ikirere, cyane cyane mu nzego z’ingenzi nko mu buvuzi no mu burezi.

Muri make, gukuraho NVC bitanga itandukaniro rigaragara mu bijyanye no kwamamaza, gutanga icyemezo cy’ibidukikije, no mu mishinga y’amasoko.

Kuba hariho NVP na NVC mu mateka mu irangi rya UV

Kuva mu mpera za 1990 kugeza mu ntangiriro za 2010, NVP na NVC byari ibintu bisanzwe bigabanya ubushyuhe mu buryo bwa gakondo bwa UV bitewe nuko byagabanyaga ubushyuhe n'ubushobozi bwo gukora cyane. Imiterere isanzwe ya inki z'umukara za kera yari ifite ubushyuhe bwa 15-25% NVP / NVC, mu gihe amakoti asobanutse neza ya flexographic yari afite ubushyuhe bwa 5-10%.

Ariko, kubera ko Ishyirahamwe ry’Uburayi ry’Inyik’Icapiro (EuPIA) ryabujije ikoreshwa rya monomer zitera kanseri na mutagenic, formulaire za NVP/NVC zisanzwe zirimo gusimburwa vuba n’izindi nzira zitekanye nka VMOX, IBOA, na DPGDA. Ni ngombwa kumenya ko wino zishingiye ku binyabutabire cyangwa izishingiye ku mazi zitigeze zishyirwamo NVP/NVC; izi lactam za vinyl zirimo azote zabonetse gusa muri sisitemu zo gukangura UV/EB.

Ibisubizo bya Haohui UV ku bakora wino

Nk’umuyobozi mu nganda zitunganya imirasire ya UV, Haohui New Materials yiyemeje guteza imbere irangi rya UV na sisitemu za resin zitekanye kandi zirinda ibidukikije. Dushyigikira by’umwihariko abakora irangi kuva ku irangi gakondo bakajya ku bisubizo bya UV binyuze mu gukemura ibibazo bisanzwe binyuze mu bufasha bwa tekiniki bwihariye. Serivisi zacu zirimo ubuyobozi bwo guhitamo ibicuruzwa, kunoza ikoreshwa ryabyo, guhindura imikorere, n’amahugurwa y’umwuga, bigatuma abakiriya bacu batera imbere mu gihe hakomeje gukazwa amategeko agenga ibidukikije.

Kugira ngo ubone ibisobanuro birambuye bya tekiniki n'ingero z'ibicuruzwa, sura urubuga rwemewe rwa Haohui, cyangwa uduhamagare kuri LinkedIn na WeChat.
